Memory problems
by Peter Griffin 05 Feb '10

05 Feb '10

Hi, I'm using stunnel 4.22 with OpenSSL 0.9.7m - I am using 4.22 because of the xforwarded-for patch and 4.27 is not supported. I am running stunnel in standalone mode on a P4 3.2Ghz with 1Gb of Ram. When I start haproxy & stunnel after a reboot, free memory starts at about 750Mb then slowly degrades to about 45Mb. After 8 more hours or so of operation our site was completely unbrowsable. I checked our firewall for unusual traffic, and there were none. Running top does not indicate any processes which are consuming all that memory and that is what I find weid. Only a reboot frees up the memory. Should I be running stunnel on more Ram? stunnel -v output: [root@lb1 ~]# stunnel -version stunnel 4.22 on x86_64-unknown-linux-gnu with OpenSSL 0.9.7m 23 Feb 2007 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Global options debug = 5 pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = ALL:!aNULL:!eNULL+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none stunnel.conf: #setuid=stunnel #setgid=proxy #debug = 3 #output = /var/log/stunnel.log socket=l:TCP_NODELAY=1 socket=r:TCP_NODELAY=1 [https] accept=10.0.1.50:443 connect=10.0.1.50:80 TIMEOUTclose=0 xforwardedfor=yes

HTTP Connect proxy patch
by Dmitry Gromov 05 Feb '10

05 Feb '10

Hi! It seems like the latest patch to support HTTP Connect proxy is for 4.05 version. Any one knows if it is compatible with the latest version? If not, is there more recent version of the patch? I also wonder why this never made to the code... Seems like a very useful feature. Thanks, Dmitry -- DG NJ

My current compile-install-configure-run environment is broken with 4.30. Up to 4.29 stunnel is working ok for me. 4.30 compiles, installs but when running it (i simply start /opt/ssl/bin/stunnel) the behaviour is completely different.

Stunnel 4.3 not forwarding to server socket
by Vladimir Stariradev 28 Jan '10

28 Jan '10

Dear Stunnel users, I'm running stunnel on my server which accepts connections from my mobile phone emulator (j2me) like so: midlet app -> port:5555 stunnel -> port:6666 server. My midlet, which can be treated as a java app, uses ssl://127.0.0.1:5555 to connect to stunnel. I can establish a connection between the stunnel and the app because I can get information on the certificate. The problem is that when I send data from the midlet to the server, the server doesn't accept it, nor does it signal that anything has been received even when I have double-checked that the streams are setup. I have pasted my config and log files below. Any suggestions are fully appreciated.

need to restart stunnel if stunnel starts before network?
by Zhang Weiwu 20 Jan '10

20 Jan '10

Hello. One reason to opt for stunnel instead of ssh -L to secure a local non-ssl client is, that if user use stunnel, it can work transparently, start working only when a connection is listened, so user do not have to start ssh-L before using the client and do not have to shut it down after using the client. However these days through the use of NetworkManager, the network interfaces are often not brought up when stunnel started as a system service. Instead, the network interfaces are brought up by users, in case of wifi or wan, after user typed password. I found I have to first start network interfaces, and run /etc/init.d/stunnel restart to prepare to run the insecure client. Is there a way to run in stunnel in such a way it does nothing except listening, and can recover from network restart, which happens from time to time for road warriors like me? Thanks in advance. I didn't find answer on FAQ by the way.

Is PSK supported with openssl-1.0.0-beta3 ?
by anders nilsson 19 Jan '10

19 Jan '10

Hello I am running x64 Linux 2.6.18-92.1.22.el5 and installed OpenSSL 1.0.0-beta3 15 Jul 2009 My stunnel -version is: stunnel 4.15 on x86_64-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 I would like to run the ciphers TLS_PSK_WITH_3DES_EDE_CBC_SHA or TLS_PSK_WITH_AES_128_CBC_SHA and I wonder how I do that. My stunnel.conf contains: ciphers = PSK-AES128-CBC-SHA:PSK-3DES-EDE-CBC-SHA and the error I get is: 2009.11.05 11:32:32 LOG3[29268:47461015826624]: SSL_CTX_set_cipher_list: 1410D0B9: error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match Do I compile in the latest OpenSSL to stunnel? Isnt it a problem that the stunnel.conf does not even have the syntax to read PSK-key parameters since its most often run with RSA keys. _________________________________________________________________ Windows Live: Gör det enklare för dina vänner att se vad du håller på med på Facebook. http://www.microsoft.com/sverige/windows/windowslive/see-it-in-action/socia…

Stunnel and RTMPS
by Nimrod Aviram 11 Jan '10

Hi, I'm currently trying to use rtmps, with Red5 and Stunnel, and it doesn't work with properly signed certificates: When I use a self-signed test certificate, everything works just fine. But when I use a proper certificate (2048 bits from godaddy.com, if that matters), NetConnection.connect just doesn't work - the server doesn't get a connection. https stil works though, and the browser treats the certificate as valid, so it's probably not a problem with the certificate. I saw some earlier posts on this problem, does anyone have a solution? Any comments are welcome... thanks, Nimrod

server refuses connection by STARTTLS
by Tsurutani Naoki 10 Jan '10

10 Jan '10

Hi, I want to connect to SMTP server by STARTTLS, from MUA who does not support STARTTLS. However, I cannot connect to the server with recent stunnel. On Windows XP, my stunnel.conf is the following: client=yes debug=notice output=C:\logs\stunnel.log service=stunnel [smtp_server] accept=127.0.0.1:10025 connect=smtp.example.com:587 protocol=smtp stunnel version 4.27 or 4.29 is started as service, by "C:\Network\stunnel\stunnel.exe" -service -install c:\home\turutani\INI\stunnel.conf I cannot connect with OpenSSL distributed via stunnel. Then I changed the OpenSSL DLL, and found that I can connect with OpenSSL older than 0.9.8i, while that newer than 0.9.8j fails. But it works by adding "sslVersion=all" or "sslVersion=SSLv2" to configuration file. I also ran stunnel on FreeBSD, and found the same result about SSL version. Here is a debug level log, with no "sslVersion=" or "sslVersion=SSLv3": 2010.01.08 09:50:06 LOG7[2372:3760]: RAND_status claims sufficient entropy for the PRNG 2010.01.08 09:50:06 LOG7[2372:3760]:

I finally seem to have stunnel up ,and running with Agent ver 2.0 newsreader. I had to do some more research on this, and thru patience, and many config changes I believe stunnel is now supplying SSL for my agent newsreader. Not an easy task for a total windows dummy like me though. Never have got the Linux thing. I guess it is the having to deal with scripts issue continually that scares the hell out of me!! IF anyone needs the procedure in the future for this let me know and I will send it to them! jb

How to setup forte agent to work with stunnel latest version.
by johnnyb mee 02 Jan '10

02 Jan '10

I have been trying to get stunnel to work with Agent 2.0 newsreader so that I can use SSL from my news server. I have read the faq and gone thru alot of previous posts concerning this and found this one entry suggestion for the stunnel.config file in order to setup SSL to work with Agent which unfortunately has no SSL capabilities at all. It is suggested to use this entry to get both the newserver and client to work thru using stunnel as a proxy server service basically. c:\program files\stunnel -c -d 127.0.0.1:119 -r unlimited.newshosting.com:563 I copied and pasted the entry changing the usenet server to the above, and now I can no longer get stunnel to start at all. I am getting an error message stating I need to check the logfile to determine what is causing the error. The actual logfile error is as follows: 2010.01.02 23:12:59 LOG7[3456:1988]: RAND_status claims sufficient entropy for the PRNG 2010.01.02 23:12:59 LOG7[3456:1988]: PRNG seeded successfully 2010.01.02 23:12:59 LOG7[3456:1988]: Certificate: stunnel.pem 2010.01.02 23:12:59 LOG7[3456:1988]: Certificate loaded 2010.01.02 23:12:59 LOG7[3456:1988]: Key file: stunnel.pem 2010.01.02 23:12:59 LOG7[3456:1988]: Private key loaded 2010.01.02 23:12:59 LOG7[3456:1988]: SSL context initialized for service pop3s 2010.01.02 23:12:59 LOG7[3456:1988]: Certificate: stunnel.pem 2010.01.02 23:12:59 LOG7[3456:1988]: Certificate loaded 2010.01.02 23:12:59 LOG7[3456:1988]: Key file: stunnel.pem 2010.01.02 23:12:59 LOG7[3456:1988]: Private key loaded 2010.01.02 23:12:59 LOG7[3456:1988]: SSL context initialized for service imaps file stunnel.conf line 55: No '=' found 2010.01.02 23:12:59 LOG3[3456:1988]: Server is down As you can ascertain I am no linux expert at all so working with startup scripts such as this is challenging to say the least. Is the entry I pasted into the config file incorrect or not pointing to the right path for the config file directory or what do you think is missing? I am using Windows XP Pro and know that the actual file for the config resides in windows/system32 folder. Any input on this would be very much appreciated and thanks in advance all. jb

Using stunnel instead of SSL API
by Vladimir Stariradev 23 Dec '09

23 Dec '09

Hi Guys, I'm working on a java mobile app (J2ME MIDP 2.0) which connects to a java server, which I created. The java mobile app is an instant messenger. I want to use stunnel to encrypt the communication between the app and the server. At the moment the server runs on my localhost on port 5555 and accepts connections from the mobile device emulator I have running on the same machine. Eventually I want to transfer the mobile app on to my mobile and use it from there. My machine is running the following versions stunnel 4.29 on x86-pc-mingw32-gnu with OpenSSL 0.9.8l on Windows 7 x64. I have not yet configured a pam or config file but I would like to continue listening on port 5555 with my own certificate (but for now any will do). Will the fact that I'm running both my server and device emulator on one machine mean that it'll bypass stunnel and I'll never know if it works or not? Should I have my mobile app use SecureConnection (SSL encrypted) class? In that case, I'd have to make the server listen for SSL connections too. That would defeat the purpose of stunnel. Help on configuration is welcome. Thanks for reading, I'm looking forward to your replies Vladimir

privileges not dropped before libwrap processes are spawned
by Micah Anderson 21 Dec '09

21 Dec '09

Hi, I recently stumbled on http://mirt.net/pipermail/stunnel-users/2008-May/001977.html which is exactly what I am seeing with version 4.27 of stunnel, namely the daemon is not switching to the setuid/setgid specified in the config before it is spawned. This means that I get 6 processes, 5 run as root with only one (albeit the one lisenting on the specified sockets) dropping privs to the specified user. The follow-up response from Mike was: I'll modify stunnel to delay spawning libwrap processes until privileges are dropped. and indeed, I find in the Changelog file for version 4.25 the following Bugfixes: * Bugfixes - Spawning libwrap processes delayed until privileges are dropped. However, it seems that either this fix either didn't make it in, or it somehow managed to creep its way back out because it is happening in 4.27. Thanks, micah

BBwin hanging windows
by Gregory Wege 18 Dec '09

18 Dec '09

Hey Guys, We have the following problem: Bbwin is sending traffic to 2 monitoring servers and is encrypted via stunnel. If one of the monitoring servers goes down, the number of ports being used by bbwin client increases to the point where the box is unusable - no more ports available on the windows box being monitored. If we kill the bbwin process, the problem goes away temporarily - after a short period of time, the problem returns. The problem continues even after the failed hobbit server recovers, and only clears up when we kill the bbwin process. * Windows version Server 2003 * bbwin versions 0.11, 0.12 * stunnel version 4.25 * hobbit server version 4.2.2 Output of the stunnel log shows the following error: 2009.12.16 06:56:19 LOG7[2336:2460]: New thread created 2009.12.16 06:56:19 LOG7[2336:4016]: hobbit_ssl started 2009.12.16 06:56:19 LOG7[2336:4016]: FD 356 in non-blocking mode 2009.12.16 06:56:19 LOG7[2336:4016]: TCP_NODELAY option set on local socket 2009.12.16 06:56:19 LOG5[2336:4016]: hobbit_ssl accepted connection from 127.0.0.1:1725 2009.12.16 06:56:19 LOG7[2336:4016]: FD 396 in non-blocking mode 2009.12.16 06:56:19 LOG6[2336:4016]: connect_blocking: connecting 10.132.55.24:1982 2009.12.16 06:56:19 LOG3[2336:4016]: connect_blocking: connect 10.132.55.24:1982: No buffer space available (WSAENOBUFS) (10055) 2009.12.16 06:56:19 LOG5[2336:4016]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2009.12.16 06:56:19 LOG7[2336:4016]: hobbit_ssl finished (0 left) Can something be added to my stunnel.conf to prevent this from happening? Any help would be greatly appreciated. Thanks.

Tunnel iPhone - Server
by LoLoVioLo 14 Dec '09

14 Dec '09

Hi all, It is my first post. Sorry if common question but didn't find answer in archives or google. The fact is that I am using an iPhone with a data plan that only allow ports 80 and 443 (http and https). My aim is to be able to use all ports (mail, ftp, msn, etc). The idea is to tunnel all TCP connections between my computer here and my server at home. iPhone <----port-443----> Linux Server <----all-ports----> Internet I know there is alternatives for each service (webmail, webmessenger, etc.) but I think that it is technically possible to have something running that allow using of usual software. I also know that this usage is typically VPN but there is no VPN client for iPhone that allow custom ports and not sure my data plan can route GRE protocol. By the way STunnel was ported to the iPhone. There is some hope. I am not sure Stunnel is the best way to do that and not even sure that Stunnel can do it but hope you can advice. Thanks for your help. LoLoVioLo

Question (simple one I think)
by Reinier van der Gugten 09 Dec '09

09 Dec '09

Question: On the server, port 443 is already in use by a different service. However I require STunnel to communicate also on port 443. I thought, that perhaps I can obtain a second IP address and forward that trafic from the router to port 444 (or any other avail port). Then I can let Stunnel listen to port 444 and thus it would work. The firewall has to translate the 444 back to the 443 when transmitting data ofcourse. Is this the right way to go? Or ca I do this using one and the same IP (but then there would be 2 services listning to the same port right)? Thanks. Reinier

So... my question is has anyone else made a similar change to get the code to compile on AIX 5.3? If not, can you please tell me what configuration options you used to make stunnel work. Thanks for any help you can provide. I am at my wits end here and pretty much my capability in compiling code. Thanks in advance, Geoff

Greetings, I've noticed some problems with v4.28 (posted in this group). Is there any compelling reason to upgrade from 4.27 to 4.28? Or, should we wait for the problems in 4.28 to be fixed in a new version and then upgrade? Regards, Jeff

problem with -fd option on Linux
by Sorkin, David 21 Nov '09

21 Nov '09

I'd like to report an interesting problem I found that occurs on Linux but not Solaris when using the -fd 0 option to read the stunnel configuration in from stdin. I am using stunnel to establish client tunnels on the fly for one time use by programs such as rsync. The client config file is generated automatically with some dynamic parameters. After the client tunnel is established a client program connects to the specified port on localhost. This works fine on Solaris but on Linux I found that the client program has to be invoked *twice* before it works. My work around is to write the config to a temp file and starting stunnel with the location of the file as its argument instead of writing to its standard input. I am using tcp wrappers to protect the stunnel servers and to limit the connects to the client to localhost. This isn't an issue for me anymore but it took a bit of troubleshooting to figure out. On Solaris I am running the same version of stunnel, openssl, etc... all compiled very similarly. One difference could be iconv but I don't know enough about it to say.

Hello, I have a problem ... on my network i have more than one proxy server, and y use Stunnel for a remote RDP. if my computer is directly connected to internet there is no problem. If i connect my computer on my domain with my proxies servers i'm not able to connect me on RDP to my remote RDP server. Is it possible to indicate my proxy server to user ?

Error installing Stunnel-4.28

12 Nov '09

I could not get Stunnel-4.27 to work as described in a previous post on Mon Nov 9 17:12:38 CET 2009 to which nobody responded. So I tried installing the latest version, Stunnel-4.28, and received the following error when running the 'make' command... options.c: In function ‘service_options’: options.c:1139: error: ‘SSL_OP_NO_TICKET’ undeclared (first use in this function) options.c:1139: error: (Each undeclared identifier is reported only once options.c:1139: error: for each function it appears in.) options.c: In function ‘parse_ssl_option’: options.c:1709: error: ‘SSL_OP_NO_TICKET’ undeclared (first use in this function) make[1]: *** [options.o] Error 1 make[1]: Leaving directory `/tmp/stunnel-4.28/src' make: *** [all-recursive] Error 1 The output for 'openssl version' is: OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Can anyone help me with either problems please?

Re: [stunnel-users] stunnel-users Digest, Vol 64, Issue 8
by Michael Wilson 12 Nov '09

Thanks Ludholf, Re Q2 - Solved. Re Q1 - Thanks, but I should have been clearer, I wanted an automated solution. My nightly Blat e-mails come from a command line .cmd file. I have recently added a javascript to check if stunnel is active and, if not, start it before my e-mails. Now I would like to create a similar script that, if stunnel is running, stops it after my e-mail. I may just have to use Windows Script Host's Terminate.

Vista questions
by Michael Wilson 11 Nov '09

11 Nov '09

I am running 4.27 on Vista and can successfully start it and use Blat to e-mail via my gmail account using stunnel.

Update docs to remove RLE as compression choice
by Joe Kemp 06 Nov '09

06 Nov '09

I just confirmed that RLE compression is not truly implemented in OpenSSL. It would be helpful to remove it from the stunnel docs so people don't think it's an option to compress data. ZLIB is it. And yes I spent a good bit of time last year with Wireshark to determine RLE vs ZLIB compression ratios in stunnel. Shockingly ZLIB was always better... One other note that may be important for some people is that 0.9.7 openssl is not compatible with 0.9.8 with respect to zlib compression. Joe A.

Is PSK supported with openssl-1.0.0-beta3 ?

Hello I am running x64 Linux 2.6.18-92.1.22.el5 and installed OpenSSL 1.0.0-beta3 15 Jul 2009 My stunnel -version is: stunnel 4.15 on x86_64-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 I would like to run the ciphers TLS_PSK_WITH_3DES_EDE_CBC_SHA or TLS_PSK_WITH_AES_128_CBC_SHA and I wonder how I do that. My stunnel.conf contains: ciphers = PSK-AES128-CBC-SHA:PSK-3DES-EDE-CBC-SHA and the error I get is: 2009.11.05 11:32:32 LOG3[29268:47461015826624]: SSL_CTX_set_cipher_list: 1410D0B9: error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match Do I compile in the latest OpenSSL to stunnel?

Tunneling udp over stunnel
by D-503 03 Nov '09

03 Nov '09

Hi, I'm trying to setup some kind of DNS-encryption with the usage of stunnel: https://www.privacyfoundation.de/wiki/HTTPS-DNS/TLS-DNS . This setup is working but pretty pretty slow. One DNS-request takes really long, about 5-6 seconds! I'm wondering why this happens. On the server is running stunnel 4.22 and on the client stunnel 4.25. The config is as described in the link above. What happens in the logs when I do one dns-request, you can see in the attachments of this mail. Something interesting is, if I do a: dig @localhost google.com it takes 5-6 seconds to finish. But if I execute it, abort it directly and execute it again, I get immediatly an answer! This works reproducably. Have you any idea? Could the error be with open/closed connections or some timeouts in stunnel? greetings D-503

Help with basic stunnel configuration
by Craig Watkinson 30 Oct '09

30 Oct '09

Hello, I have been trying to enable stunnel on a HPUX server, and whilst I thought it was going to be simple, I have not been able to make it work so far. We have a webserver and due to some pages being hardcoded to port 8080 it can't support SSL without a lot of code changes. As a short term workaround I am trying to use stunnel in server mode to provide a HTTPS interface. I expected this to be a very simple matter of accepting connections on port 443 and connecting to port 8080, but it's not working. We're using an old version of stunnel (4.04) however this is the version bundled with the HPUX OS we have. When stunnel is started there are no errors (log file output below) and netstat shows that a process is listening on port 443, however a browser (tried IE6 and Firefox) doesn't display anything. Connecting to port 8080 shows the application as expected. I have run a wireshark trace at the client end, and it seems that the stunnel server is not responding to the initial "Client Hello" message. Only 3 packets are seen: C->S SYN S->C SYN,ACK C->S SSL Client Hello My guess is that the ssl server is not starting up correctly, however everything looks ok in the logfile, although it might not be completing. Nothing is displayed in the log when I try to connect to port 443. Any help would be much appreciated as I am stuck!

Connections begin resetted
by Roman Medina-Heigl Hernandez 26 Oct '09

26 Oct '09

Hello, Till some recent time, I was using "socat" (http://www.dest-unreach.org/socat/) to create a SSL-wrapper (in a way similar to what "stunnel" does). I was using: === socat -ly -d -d openssl-listen:443,bind=X.X.X.X,fork,reuseaddr,cipher=HIGH:3DES:MD5,cert=server-cert.pem,key=server-key.pem,verify=0 tcp4:Y.Y.Y.Y:P === It was working pretty well, without interruptions, although it got some estability problems when passing 1-2 months (server apparently get stuck). So I decided to give a try to "stunnel". I switched to "stunnel" and problems arise... I'm experimenting *very* frequent connection cuts. If I examine daemon.log (I'm using Debian 5), I have: Oct 20 12:06:36 hetzner stunnel: LOG3[3677:3083029392]: SSL_read: 140EC071: error:140EC071:SSL routines:SSL2_READ_INTERNAL:bad mac decode Oct 20 12:06:36 hetzner stunnel: LOG5[3677:3083029392]: Connection reset: 315484 bytes sent to SSL, 50471 bytes sent to socket So it seems stunnel is closing the connection due to a "bad mac decode" error. My environment (client and server) have not changed, I only switched "the transport" (socat -> stunnel). Any idea why is it failing now? Moreover, if I switch back to socat, cuts disappear. Is stunnel buggy? Am I missing some config/tunning at the SSL/socket level? My current config is: roman@hetzner:~$ stunnel4 -sockets Socket option defaults: Option Accept Local Remote OS default SO_DEBUG -- -- -- 0 SO_DONTROUTE -- -- -- 0 SO_KEEPALIVE -- -- -- 0 SO_LINGER -- -- -- 0:0 SO_OOBINLINE -- -- -- 0 SO_RCVBUF -- -- -- 87380 SO_SNDBUF -- -- -- 16384 SO_RCVLOWAT -- -- -- 1 SO_SNDLOWAT -- -- -- 1 SO_RCVTIMEO -- -- -- 0:0 SO_SNDTIMEO -- -- -- 0:0 SO_REUSEADDR 1 -- -- 0 SO_BINDTODEVICE -- -- -- -- IP_TOS -- -- -- 0 IP_TTL -- -- -- 64 TCP_NODELAY -- -- -- 0 root@hetzner:~# stunnel4 -version stunnel 4.22 on i486-pc-linux-gnu with OpenSSL 0.9.8g 19 Oct 2007 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel4.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none My stunnel.conf is very simple. Apart from cert setup, the tunnel is something like: === [tunelserv] accept = X.X.X:X:443 connect = X.X.X.X:P === Any idea? Thank you in advance. Cheers, -Roman

multiple domain certificates
by Andrew Farmer 22 Oct '09

22 Oct '09

Does stunnel support multiple domain certificates? I am trying to get stunnel to work with multiple domains on a machine that can have only one IP address. (It is an amazon EC2 instance - they do not support multiple IPs per instance) It seems to me that the only way to get this to work is with a multiple domain certificate, which I believe is called a "Unified Communications Certificate". Does stunnel support these? Thank you so much, Andrew -- View this message in context: http://www.nabble.com/multiple-domain-certificates-tp25897355p25897355.html Sent from the Stunnel - Users mailing list archive at Nabble.com.

https problems over TLSv1
by Al Gonzalez 19 Oct '09

19 Oct '09

Thank you in advance for any assistance you can provide... I am trying to talk to a UHF radio (from a PC) over a secure channel, but having some difficulties. Please let me provide just a little background so you know why I’m doing what I’m doing. In the existing system, Internet Explorer (IE) is the client that talks to this radio. When the radio boots up, it sends a webpage over Ethernet to IE and (after the user login), a secure link is established, and the radio can be controlled from IE – the various webpages change as the user maneuvers through the various dropdowns, etc. We’ve been asked to automate this interface now for a production environment. The client is going to be replaced with a PC connected to a great deal of test equipment, and the server will now send XML instead of html to the client. The client is being developed in LabVIEW (from National Instruments) – this has made this task even more challenging. As all of this secure stuff is new to me, I spent many hours just trying to understand the problem(s) and the lingo. As LabVIEW has some limitations in this area, I found that Stunnel was my best option. Using TCP/IP and sending http to the radio (shown below), I’ve been able (in a non-secure mode, without Stunnel) to communicate and get the opening screen (html) to be returned to me (the XML server output is currently being developed) and displayed in a LabVIEW window. GET / HTTP/1.1 Host: 10.4.32.1 Connection: Keep-Alive Authorization: Basic YWRtaW46UgEkJHdvtmQx Credentials: admin:Password I downloaded the binary version of Stunnel.exe (version 4.27 with OpenSSL 0.9.8k dated Mar 2009), then modified the LabVIEW code to call (using a command line approach) Stunnel. In this way, I can’t provide any (dash) options, so it’s completely dependent on the stunnel.conf file. After a number of attempts, I was able to get the client to bind to the server (I think), but I see nothing being returned to me (no html). I must use TLSv1, and ciphers = DES-CBC3-SHA. I’ve seen examples on stunnel.org that show a great deal more handshaking information than I’m seeing, so I’m wondering if I’m missing some detail in my conf file. For example, my log file ends like this 2009.10.16 13:18:49 LOG7[4812:4776]: FD 208 in non-blocking mode 2009.10.16 13:18:49 LOG7[4812:4776]: SO_REUSEADDR option set on accept socket 2009.10.16 13:18:49 LOG7[4812:4776]: https bound to 10.4.1.8:443 But the example I mentioned goes on after the “https bound” and adds things like … 2009.08.04 12:15:55 LOG7[16648:22996]: proxy accepted FD=320 from 127.0.0.1:48086 2009.08.04 12:15:55 LOG7[16648:22996]: Creating a new thread 2009.08.04 12:15:55 LOG7[16648:22996]: New thread created 2009.08.04 12:15:55 LOG7[16648:8540]: proxy started 2009.08.04 12:15:55 LOG7[16648:8540]: FD 320 in non-blocking mode 2009.08.04 12:15:55 LOG7[16648:8540]: TCP_NODELAY option set on local socket 2009.08.04 12:15:55 LOG5[16648:8540]: proxy accepted connection from 127.0.0.1:48086 2009.08.04 12:15:55 LOG7[16648:8540]: FD 340 in non-blocking mode 2009.08.04 12:15:55 LOG7[16648:8540]: proxy connecting 89.149.253.125:8080 2009.08.04 12:15:55 LOG7[16648:8540]: connect_wait: waiting 10 seconds 2009.08.04 12:15:56 LOG7[16648:8540]: connect_wait: connected 2009.08.04 12:15:56 LOG5[16648:8540]: proxy connected remote server from 192.168.2.3:48088 2009.08.04 12:15:56 LOG7[16648:8540]: Remote FD=340 initialized 2009.08.04 12:15:56 LOG7[16648:8540]: TCP_NODELAY option set on remote socket 2009.08.04 12:15:56 LOG7[16648:8540]: SSL state (connect): before/connect initialization 2009.08.04 12:15:56 LOG7[16648:8540]: SSL state (connect): SSLv3 write client hello A 2009.08.04 12:15:56 LOG7[16648:8540]: SSL state (connect): SSLv3 read server hello A . . . 2009.08.04 12:15:57 LOG6[16648:8540]: SSL connected: new session negotiated 2009.08.04 12:15:57 LOG6[16648:8540]: Negotiated ciphers: AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 That make’s me think that I’m not quite there yet. I’ve attached my stunnel.conf, my log file, and the http request I’m making (above). I’m hoping you can find some flaws in my conf file that will get me closer. Other than receiving html, I’m not sure how to know that I truly have a secure connection. I’m thinking I should see a little more in my log file, but I’m not sure. The other thing I’m not sure about (as I’ve heard differing thoughts) is whether I have to Encrypt my http commands, or does stunnel take care of that somehow? If I have to encypt, how would I go about doing this? Also, (and I’m getting ahead of myself) do I have to open and close a session every time I want to talk, or do I somehow leave the channel open? I’ve read about Session Resumption, but I’m not sure if that is something I need to setup in the conf file, or if that can even be controlled by Stunnel.

MySQL replication with stunnel, connection closed after some time
by Marcel Kirsch 16 Oct '09

16 Oct '09

Hello, I have a problem regarding stunnel and MySQL replication. I use replication to keep our database synchronous with a second database, which stands in our building. The secure connection via stunnel works and "SHOW SLAVE STATUS;" shows, that the replication is working. Because the master database is rarely used at the moment, sometimes there are no changes (insert, update or delete) made for an hour. Unfortunately it seems that stunnel disconnects the connection between the databases after some time. The client database still thinks that it is connected to the master server, because it still is connected to port 3307 (which is stunnel of course). So now the changes made in the master database are no longer replicated. Is there any way to configure stunnel to keep the connection between the to servers alive even after an hour of zero traffic? I thought that TIMEOUTidle would be the answer to my problem, but it had no effect. I really hope you can help me and thanks for your suggestions in advance. Greetings, Marcel Kirsch This is my current configuration: Client: ; Certificate/key is needed in server mode and optional in client mode cert = /etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem

I think the timeout is caused by the TCP state expired rater than by stunnel. I think enabling TCP keepalives could be an effective workaround: socket = l:SO_KEEPALIVE=1 socket = r:SO_KEEPALIVE=1 The trick is to generate some traffic on an idle connection to convince the network device that this TCP connection is not dead. An alternative solution would be to increase the TCP state timeout on the network device. Best regards, Mike

bind error when specifying hostname

Hi! I'm not sure if this message was sent to the mailing list the first time... I was not subscribed before but I am now. I'm trying to configure stunnel to use a different CERT depending upon the hostname that my server is accessed on. (Same server has multiple hostnames) Is this feature supported? I didn't get very far before running into issues. This configuration works: (so I know nothing else is bound on port 443) [https] accept = 443 ... etc ... This configuration fails: [https] accept = nmw3.com:443 ... etc ... with this error: 2009.10.09 14:49:18 LOG3[31137:3086100144]: Error binding https to 75.101.155.94:443 2009.10.09 14:49:18 LOG3[31137:3086100144]: bind: Cannot assign requested address (99) So I tried a simpler configuration: [https] accept = 127.0.0.1:443 ... etc ... and that fails with this error: 2009.10.09 14:56:28 LOG3[31222:3086722736]: Error binding https to 127.0.0.1:443 2009.10.09 14:56:28 LOG3[31222:3086722736]: bind: Address already in use (98) Appreciate all your help!

Sometime near 2007-11-11 00:15 -0500, Marcio Marchini shouted: > Researching online one can see that WebDAV's spec requires that they > check both src and dest URLs for protocol & port. But with some proxies or > SSL fronts like stunnel, only one of the URLs is rewritten, so one goes as > http and the other as https. Here's one person explaining it, much better > than me: http://svn.haxx.se/users/archive-2006-03/0549.shtml Stunnel doesn't currently have the ability to scan and re-write the plaintext. For HTTP redirects it could possibly be implemented (re-write only the response before ^$, and redirects aren't chunked and don't have content lengths to work with, etc) but you'd still need enough HTTP logic to handle keepalives and such. It's not trivial and not likely. Another option would be to have something already HTTP aware doing the rewriting in between stunnel and subversion. A re-writing proxy. Another option would be to use mod_rewrite in apache to rewrite the urls. But the best way would be to just use SSL inside apache and drop stunnel entirely. -- Brian Hatch The best way to accelerate Systems and a Windows machine is at Security Engineer 9.8 meters per second http://www.ifokr.org/bri/ squared.

Weird verify behaviour using intermediate CAs
by Simon Vallet 05 Oct '09

05 Oct '09

Hi, we're trying to make use of stunnel here for proxy purposes : any certificate-authenticated SSL client connection from the Internet would be forwarded to some internal server. This works fine, but I found some surprising behaviour when verifying client certificates. Consider the following setup, using an intermediate client CA : * RootCA ** UserCA1 *** UserCert1 ** UserCA2 *** UserCert2 To make this work, it seems I only have to include the Root CA certificate in either a CAfile or a directory of trusted certificates. I would have expected to have to include the intermediate CA (which is signing the user certificate), but it seems it is not the case. What worries me is that now *any* end-entity certificate which has been issued by *other* intermediate CAs is accepted as valid, i.e. UserCert2 is accepted as valid, even if I don't include UserCA2 anywhere in the configuration. Is this really the intended behaviour ? If not, what would I be missing ?

Advanced Config Question-
by Dave Fazio 30 Sep '09

30 Sep '09

Group, Need help confirming Stunnel can be configured the following way: I have a server that has 5 local IPs, mapping to 5 public IPs on the outside. For example purposes, my local IPs are "A", "B", "C", "D", and "E"... If I connect to a stunnel port configured to "C", will Stunnel route the request outbound on "C" or will it use "A" outbound? The way I have it configured, it's using "A" apparently, no matter what local stunnel IP I bind my connection to. And help will be greatly appreciated. - Dave Windows Server 2003 64-bit Stunnel as a Service Example Config: [Connection-A] accept = 10.5.12.57:9000 connect = outbound.example.server:145 TIMEOUTidle = 4 [Connection-B] accept = 10.5.12.58:9005 connect = outbound.example.server:145 TIMEOUTidle = 4

Can stunnel be used for a local smtp server, that does not support upstream SMTP AUTH, to connect to an smtp server that requires it? Thanks, John -- John Conover, conover(a)rahul.net, http://www.johncon.com/

Problems implementing certificate
by Marcelo Iturbe 15 Sep '09

15 Sep '09

Hello, I am using Stunnel 4.27 binary version on Windows 2003 server. In the stunnel.pam file I did the following: In the -----BEGIN RSA PRIVATE KEY----- section, I placed the same text that appeared in the -----BEGIN NEW CERTIFICATE REQUEST----- when I purchased the certificate In the -----BEGIN CERTIFICATE----- section I placed what verisign returned to me. When I try to load Stunnel I get the following error messages: : RAND_status claims sufficient entropy for the PRNG : PRNG seeded successfully : SSL context initialized for service gmail-pop3s : Certificate: stunnel.pem : Error reading certificate file: stunnel.pem : error stack: 140DC009 : error:140DC009:SSL routines:SSL_CTX_use_certificate_chain_file:PEM lib : error stack: 906700D : error:0906700D:PEM routines:PEM_ASN1_read_bio:ASN1 lib : error stack: D08303A : error:0D08303A:asn1 encoding routines:ASN1_TEMPLATE_NOEXP_D2I:nested asn1 error : error stack: D07803A : error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1 error : SSL_CTX_use_certificate_chain_file: D0680A8: error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag : Server is down Any thoughts as to where I went wrong?

You can modify your stunnel.conf, there are lots of examples on the web to do that. Please don't use self-signed certs, you will have no end of issues, and there is NO reason to. StartCom offers free certificates, is in most browsers now, and will be included in IE by the end of September. http://blog.startcom.org/?p=205 So why would you create the headaches of using self-signed certs?

Hi Sorry for my question because it is too elementary but I need some help. I want to use stunnel for one of our projects on an HP Itanium server that have HP UX 11i v3 This is result for #uname –a command : HP-UX xxxxx B.11.31 U ia64 2210092972 unlimited-user license I want to start stunnel as client . I found an stunnel in ‘/opt/hpws/apache’ folder. 1- May I use this stunnel for my project? 2- If it is possible how I can start it ? I added one line to /etc/services and tried to start : stunnel –d …. (according to a document) .But it seems that this version don’t support this option. Best Regards, Mostafa

Maximum number of services
by Malenfant, Andre 04 Sep '09

04 Sep '09

Hi, we have ran into a problem and we have identified that we have reached the limit of 64 services in stunnel. I have seen some info on the net for a possibility or increasing that limit to 256 using the poll() method. There is a patch available for that but for an older version of stunnel. Is there a configuration that I can do to enable that on version 4.20? If not, what are my other options? Set-up a second stunnel? Thanks André

Maybe it doesn't correctly determine it's own location in relation to the working directory. You might try to specify stunnel.conf on the command line, e.g. MyProcID = Shell("stunnel\stunnel stunnel\stunnel.conf") or MyProcID = Shell("stunnel\stunnel .\stunnel.conf") or something along those lines.

Random Client Ports
by Matt Keoppel 01 Sep '09

01 Sep '09

We are currently trying to add Stunnel to our application. Each time one of our clients try to connect to the server it seems to make its call from a random port. We have set up the server config file to be: [OurApp] accept = 15366 connect = 15365 The config file on our client is set up as: client = yes [OurApp] accept = 1308 connect = [serverIp]:15366 The problem that we are having is that the source port on our client changes every time we try to send data from our client to our server. So one time we send data the port will be 1308 and the next time will be 1309. We also tried to set up multiple configurations that were configure to accept on many ports and all connecting to [serverIP]:15366. Is there any way to get Stunnel working with our dynamic client port? Thanks, MK

Help compiling - rpath issues
by Jay Martel 18 Aug '09

18 Aug '09

Hello, I am trying to avoid LD_LIBRARY_PATH and thus want to compile in the run time library path. I have tried various options to configure, hacking the LDFLAGS and CC lines in the Makefile, changing libtool varialbes, etc. but my resulting binary never has the library path inside. Things I have tried: LDFLAGS=-R/app/versions/local/3/lib LDFLAGS=-L/app/versions/local/3/lib LDFLAGS=-Wl,--rpath -Wl,/app/versions/local/3/lib libtool variables that seem related but I cannot figure out: hardcode_minus_L=yes hardcode_libdir_flag_spec="\${wl}--rpath \${wl}\$libdir" I am using stunnel-4.27 and the configure and libtool it contains. Here is the output of gcc -v: Reading specs from /app/versions/local/3/lib/gcc/i386-pc-solaris2.10/3.4.5/specs Configured with: /opt/autobuild/workdir/gcc-3.4.5/configure --prefix=/app/versions/devtools/3 --with-gnu-ld --with-ld=/app/versions/devtools/3/bin/ld --with-gnu-as --with-as=/app/versions/devtools/3/bin/as --libdir=/app/versions/local/3/lib --with-local-prefix=/app/versions/local/3 --with-gxx-include-dir=/app/versions/local/3/include/c++ --enable-languages=c,c++,objc Thread model: posix gcc version 3.4.5 I am having the same issue with Solaris 10 on i86pc and sparc architectures. Here is the last bit of my make output: /bin/bash ../libtool --tag=CC --mode=link gcc -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/app/versions/local/3/include -o stunnel file.o client.o log.o options.o protocol.o network.o resolver.o ssl.o ctx.o verify.o sthreads.o stunnel.o pty.o libwrap.o -lz -ldl -lsocket -lnsl -lpthread -L/app/versions/local/3/lib -lssl -lcrypto gcc -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/app/versions/local/3/include -o stunnel file.o client.o log.o options.o protocol.o network.o resolver.o ssl.o ctx.o verify.o sthreads.o stunnel.o pty.o libwrap.o -lz -ldl -lsocket -lnsl -lpthread -L/app/versions/local/3/lib -lssl -lcrypto The libtool line should show my rpath setting, I think. How do I get libtool to honor the rpath settings? Should I be asking the libtool maintainers? I check the resulting binary using "strings stunnel | grep app" and my library directory never shows up. Many thanks in advance. -Jay Martel _________________________________________________________________ Windows Live: Make it easier for your friends to see what you’re up to on Facebook. http://windowslive.com/Campaign/SocialNetworking?ocid=PID23285::T:WLMTAGL:O…

Thanks for the suggestion, I was able to make the necessary changes and pass the configure and make process. Unfortunately, after uploading and running the app, the app will not run: # ls -al /tmp -rwxrwxrwx 1 root root 2434012 Aug 12 01:44 stunnel -rw-r--r-- 1 root root 1148 Aug 12 01:37 stunnel.conf -rw-r--r-- 1 root root 1977 Aug 12 01:44 stunnel.pem drwxr-xr-x 1 root root 0 Dec 31 1969 var # cd /tmp # ./stunnel -sh: ./stunnel: not found The file is obviously there, with execute permissions. What is failing?? Thank you > checking for "/dev/ptmx"... configure: error: cannot check for file > existence when cross compiling. > > Give me your suggestions. Check that /dev/ptmx exists on your router; it does on my Buffalo router with Tomato. If it does, then hack the configure script to force the test to return true. A search in the script for ptmx should take you right to the test. Good luck, Andrew. -- Be Yourself @ mail.com! Choose From 200+ Email Addresses Get a Free Account at www.mail.com!

Stunnel configure error
by hdf sdesdh 11 Aug '09

11 Aug '09

I have been receiving errors when configuring Stunnel, which I intend to cross compile for use with my Linksys WRT54GL router (Tomato firmware). When passing ./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp the configure process stops with an error. Here is the complete output. ./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp configure: WARNING: If you wanted to set the --build type, don't use --host.

stunnel, haproxy and ssl cert
by Maxim 04 Aug '09

04 Aug '09

Hello dear community. I faced some troubles for iphone: I moved separate server from hardware to AWS Cloud with SSL certificate from Register.com. It moved well, and phone application continue work with new server without any problems. Then I installed LoadBalancer (HAProxy and Stunnel) for it and moved certificate with key from configs of Apache to config of stunnel. In PC browser it continue works well, and shows me blue field near the URL as trusted. But on iPhone browser it shows just "Untrusted server certificate". Is there any difference for ssl certificate for stunnel and Apache? I understand that there is very specific question, but would you have any ideas about it? *Config of stunnel:* cert = /usr/local/etc/stunnel/stunnel.pem chroot = /usr/local/var/lib/stunnel/ setuid = nobody setgid = nobody pid = /stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 7 output = stunnel.log [https] accept = 443 connect = 80 xforwardedfor=yes TIMEOUTclose = 0 *Patch for stunnel* http://haproxy.1wt.eu/download/patches/stunnel-4.22-xforwarded-for.diff need to make work "xforwardedfor=yes" *# stunnel -version* stunnel 4.22 on i686-pc-linux-gnu with OpenSSL 0.9.8b 04 May 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none * # uname -a* Linux domU-12-31-38-00-35-07 2.6.18-xenU-ec2-v1.0 #2 SMP Tue Feb 19 10:51:53 EST 2008 i686 athlon i386 GNU/Linux * # openssl version* OpenSSL 0.9.8b 04 May 2006 *And logs from stunnel when iphone tryed to conenct* 2009.08.04 08:20:16 LOG7[31023:3081598672]: https accepted FD=15 from 24.5.77.143:58019 2009.08.04 08:20:16 LOG7[31023:3081550736]: https started 2009.08.04 08:20:16 LOG7[31023:3081550736]: FD 15 in non-blocking mode 2009.08.04 08:20:16 LOG7[31023:3081550736]: TCP_NODELAY option set on local socket 2009.08.04 08:20:16 LOG7[31023:3081550736]: Waiting for a libwrap process 2009.08.04 08:20:16 LOG7[31023:3081550736]: Acquired libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: Releasing libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: Released libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: https permitted by libwrap from 24.5.77.143:58019 2009.08.04 08:20:16 LOG5[31023:3081550736]: https accepted connection from 24.5.77.143:58019 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): before/accept initialization 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 read client hello A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write server hello A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write certificate A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write server done A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 flush data 2009.08.04 08:20:16 LOG3[31023:3081550736]: SSL_accept: Peer suddenly disconnected 2009.08.04 08:20:16 LOG5[31023:3081550736]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2009.08.04 08:20:16 LOG7[31023:3081550736]: https finished (0 left) Thank you in advance, Max

[patch] Redirect to a fake destination if client's certificate couldn't be verified
by Jeremie Le Hen 29 Jul '09

29 Jul '09

Hi list, I've written a patch to bring in the following directives: - evilconnect - evilexec/evilexecargs The idea is when stunnel works in server mode and is asked to verify the client's certificate, it normally shuts the connection down when the latter is invalid. With these options, when the certificate can't be verified, stunnel redirects the "evil" connection to another destination. What is the purpose of this new feature ? For instance, if your company does not allow SSH connections out, you may use the following configuation: % connect = yourdomain.com:22 % evilconnect = www.yourdomain.com:80 So you will access your SSH server with your valid user certificate. On the other hand, if an over-zealous sneaky admin looks at the proxy logs and tries to connect to your stunnel, it will be redirected to an uninteresting website ;). Here is the documentation: % evilconnect = [host:]port % connect to a remote host:port when the client's certificate cannot % be verified % % This is only meaningful in server mode when connect and verify are % used. Otherwise it has the same properties as the connect option. % % evilexec = executable_path (Unix only) % execute local inetd-type program when the client's certificate can- % not be verified % % This is only meaningful in server mode when exec and verify are % used. Otherwise it has the same properties as the exec option. % % execargs = $0 $1 $2 ... (Unix only) % arguments for evilexec including program name ($0) % % Quoting is currently not supported. Arguments are separated with % arbitrary number of whitespaces. I'd like to thank Mathieu CHOUQUET-STRINGER who actually had this very good idea and implemented a proof of concept code with GnuTLS. Also, thank to Vin0x64 <vincent vin0x64 fr> who tested this patch and verified that it works. Looking forward for your remarks... thanks! Best regards, -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >

Stunnel listen on different ports
by Noel Sanchez 21 Jul '09

21 Jul '09

I have had a working stunnel conf for much time, very happy with it. [stunnel] accept = 0.0.0.0:30000 connect = 192.168.27.102:8000 I have stunnel listening on port 30000 and then sending to 192.168.27.102 on port 8000. Works good. I now want to add more listening ports to stunnel, like so: [stunnel] accept = 0.0.0.0:30000 connect = 192.168.27.102:8000 accept = 0.0.0.0:30006 connect = 192.168.27.102:8006 When I do this, stunnel only binds to 30006, per my log file: stunnel bound to 0.0.0.0:30006 And when I do a netstat -vatn: tcp 0 0 0.0.0.0:30006 0.0.0.0:* LISTEN It is not listening on port 30000 anymore. I'd like to accepts connections on many different ports, then send accordingly. Can I do this? Why does stunnel only listen to one port when I add more accept lines in its config? Noel

Re: [stunnel-users] using webdav: YES IT WORKS WITH NET USE

Well after some more tests I achieve net use to work: UseBasicAuth is VITAL on the xp client (reboot) Accordingly configure apache with basic plain text auth stunnel routing localhost:80 to remote:443 (as you did) to pass your credentials use EXACTLY this command line : net use y: \\localhost\davfolder (with no extra \) YOURPASSWORD /USER:YOURUSERNAME (this in the only way to have hhtp credentials sent to the server). tested on client: xpsp2 + kb892211 + kb911927 (IMPORTANT ALSO, needs reboot) + stunnel 427 and server apache 2.2.6/Mandriva 2008. kb907306 replaces 892211, but I have not tested with it (I think it should work). If you cannot achieve it to work please let me know the exact error message you receive from windows. Again your problem is only related to windows issue, not stunnel.

Common Name checking
by Mark Bolton 15 Jul '09

15 Jul '09

Hi, I believe this has been discussed before on the list but I wanted to get a better understanding and confirm the current situation. Is it still correct that when using verify=2, the peer's hostname is not checked (via a name service lookup) to match the Common Name in the presented certificate? With the main reason being that you cannot necessarily trust the name service? I am asking because we have a closed network in which we do trust our dns servers, and Common Name checking would be advantageous to us given the following scenario: We have is that a single (central) host that connects to multiple 'client' hosts via stunnel. The central host presents a certificate signed by our own CA. Each client has a copy of our CA's certificate and has verify=2. So when the central server connects, the client checks that the certificate presented has really been signed by our own CA. So using this mechanism, only servers (i.e. the central server) with a signed certificate are allowed to connect. All good so far, however the problem is if the signed certificate is copied (stolen) to another server. This 'other' server can connect to all the clients also. With Common Name checking, the clients could as well as checking the signature, check the presenting host has the same hostname as in the certificate. Is there anyway we can use stunnel to help us guard against this 'stolen cert' situation or if not what else could we do? Thanks, Mark

[patch] add new option send_client_info
by Henrik Riomar 13 Jul '09

13 Jul '09

Hi, The attached patch adds a new option that allows stunnel to pass on some client information to for instance a web service that uses stunnel for it's encryption. The first line of data contains the client info and if the new option is not enabled the patch does nothing. Regards, Henrik Riomar P.S. public domain.

stunnel throttling and statistics
by Laurens Van Houtven 10 Jul '09

10 Jul '09

Hi! I'm using stunnel to secure an AMQP message broker (RabbitMQ, specifically) using pre-shared certificates. This means that my backends never get to see the SSL certificate that the client used to connect -- unfortunately, it's that very backend that's the first who can decide if a message is malicious or not. In order to sort-of fix this problem, I'm using UUIDs so that the keyspace is so absurdly huge that the odds that someone will guess a key are second to none. Still, if someone is misbehaving (trying a large number of bogus keys) it would be nice to know who it is so I could stop wasting CPU time and bandwidth on them. So, I was wondering if anyone has used stunnel (vanilla or modified) to keep statistical data about who connects (which certificates). Additionally, does anyone know of a decent way to throttle per-certificate (or limit the amount of tunnels that can be opened per certificate). If all else fails I could just do normal throttling on a per-IP basis, which should get me roughly the same thing. The reason I want this is because I want to prevent users from even *trying* a large number of such keys (even though it's statistically unlikely that they'll get one) since it still takes me CPU time to process that junk. Thanks in advance Laurens

However, on modern operating systems, fork()ing is not as expensive as it looks like. In most cases, the text segment is shared between the two processes and the pages on data/BSS segments are not copied until changed ('copy-on-write').

stunnel - connection issue with larger number of connections
by Franjo Stipanovic 26 Jun '09

26 Jun '09

Hello, have anyone experienced a issue with stunnel when there's a larger number of concurrent connections (>50)? I've got my application service and stress tester for it. I've placed stunnel in front of application service because I allow clients only to connect to application service using SSL. When stress tester communicates directly with application service with 100 concurrent connections (threads) there's no issue, but when I connect over SSL (thru stunnel) more than 50% of connections fails with error : connection refused :( Seems like there's a limit in windows server for number of threads per process since stunnel does one thread per connection, right? Any idea on how can I test this further? stunnel information: stunnel 4.22 on x86-pc-mingw32-gnu with OpenSSL 0.9.8g 19 Oct 2007 Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 Global options debug = 5 RNDbytes = 64 RNDoverwrite = yes service = stunnel taskbar = yes Service-level options cert = stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none Socket option defaults: Option Accept Local Remote OS default SO_DEBUG -- -- -- 0 SO_DONTROUTE -- -- -- 0 SO_KEEPALIVE -- -- -- 0 SO_LINGER -- -- -- 0:0 SO_OOBINLINE -- -- -- 0 SO_RCVBUF -- -- -- 8192 SO_SNDBUF -- -- -- 8192 SO_RCVLOWAT -- -- -- -- SO_SNDLOWAT -- -- -- -- SO_RCVTIMEO -- -- -- 0:0 SO_SNDTIMEO -- -- -- 0:0 SO_REUSEADDR 1 -- -- 0 IP_TOS -- -- -- 0 IP_TTL -- -- -- 32 TCP_NODELAY -- -- -- 0 Software configuration: Windows Server 2003 R2 - Enterprise x64 Edition Hardware configuration: Intel Core 2 Duo 1 GB RAM Kind regards, fritz

For reducing the number of processes, you might also try to configure stunnel with --disable-libwrap. If you run stunnel from within a CGI, you will be accepting connections from localhost only anyway.

Ah, o.k. you want to use stunnel from inside a CGI. You could have the CGI dynamically write the stunnel configuration file then. Maybe you should specify 'foreground = yes' in order to avoid detaching to the background and to get stunnel's log messages written to the web server log. This depends on the CGI, of course.

Dynamic hosts
by Terry Riegel 22 Jun '09

22 Jun '09

Hello, I have just set up stunnel to allow unsecured client pop3 connections to my secured pop3 server chroot = /stunnel/ pid = /stunnel.pid setuid = www setgid = www client = yes foreground=yes [995] accept = localhost:10110 connect = mail.clearimageonline.com:995 And it works as expected. Is there a way to set it up so it can dynamically connect to any server. Something like... connect = *:995 I was able to start a new instance of stunnel with a separate config file but this seems inefficient as it starts up 6 processes each time. What I would like to do is dynamically add/subtract servers that it can connect to. My goal here is to build a webmail client that can use stunnel to do the secure connections to either POP or IMAP servers. My client software uses unsecured sockets. Any help would be greatly appreciated. Terry Riegel

Hi, I forgot a few things in my last msg, that were implied but not explicitly stated. 1.) I downloaded and installed stunnel-4.27. 2.) Im not running darwin ports. 3.) When I installed I entered the commands on the command line without ever touching xCode. 4.) I am running MAC OS 10.5.7. I will have to do a later install on MAC OS 10.4.11. 5.)

4.26 works OK, 4.27 will not POP email
by Jeff Salisbury 14 Jun '09

14 Jun '09

Greetings, We have been using Stunnel 4.26 to facilitate the sending and receiving of email with an email client that is not SSL enabled. Version 4.26 has been working great. However, when we upgrade to 4.27, we are unable to POP email (we can send email). We did not change our Stunnel.conf file. Can anyone advise us what we need to do to get 4.27 working? I've included our Stunnel.conf file contents, and the Stunnel log output below.

Hello Carter, thank you very much for your help and nice examples. I will try it in my local network. Have a good day. Mia ---- Pôvodná správa ---- Od koho: Carter Browne <cbrowne(a)cbcs-usa.com> Komu: aaa aaa <miamia(a)inMail.sk> Dátum: 8. 6. 2009 17:52:00 Predmet: Re: [stunnel-users] 1 server and more desktops Mia, I work in both Windows and Linux, so I use a Windows approach - copying files where in Linux a link would be more appropriate. Assume server.pem is the server full server certificate including the private key and client1.pem is a full client certificate including the key. The first step is to make a copy of the server certificate and delete the lines starting with -----BEGIN RSA PRIVATE KEY------ down through the blank line after -----END RSA PRIVATE KEY----- Initial I call this server-pub.pem The command: openssl x509 -in server-pub.pem -subject_hash -noout will print out the hash for the server key (as 8 hexadecimal digits), for example abcef012 Then I rename server-pub.pem to abcdef012.0 I repeat the same process for each client key, so that client1.pem in this example would have a public key named 987654fe.0 (assuming that the hash of 987654fe). In the client1 configuration: cert = client1.pem key = client1.pem verify = 3 cafile = abcdef012.0 In the server configuration cert = server1.pem key = server1.pem verify = 3 capath = capath In the capath directory is 987654fe.0 ... Plus the hashes of the other clients. In Windows, the capath is under the stunnel directory. The client certificates can also be concatenated in a single file. If you use a directory, it is not necessary to restart stunnel if you add a new client. If you use a concatenated file, you do have to restart stunnel if you add a client. There are some notes in the documentation about the structure of a concatenated file. I hope this helps.

Stunnel client hangs in background mode when smartcard is used
by John Abloyer 08 Jun '09

08 Jun '09

Hi! I have a problem when running ssh over stunnel in background mode ('foreground' out-commented in config file). In foreground mode, everything works fine. I'm using a modified OpenSSL, adding an engine that is dedicated to communicate with a smartcard reader. The scenario is: - Starting stunnel on server, extract from config file: [ssh] accept = myserver:122 connect = 22 - Starting stunnel on client, extract from config file: engine = myengine engineNum = 1 client = yes [ssh] accept = 22 connect = myserver:122 I come to here, than it hangs: ... 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server certificate A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server certificate request A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server done A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 write client certificate A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 write client key exchange A - - - - - - - But when I run in foreground mode, it all works fine and stunnel continues and I get the ssh login prompt. I'm running RHEL 5.2, OpenSSL 0.9.8*, stunnel 4.27 Any help would be appreciated Rgds JA

hello Christophe, thanks for your answer. Sorry for any misunderstanding. Well, I just wanted to ask if it is able to set stunnel for working with more certificates? So it means that I don't want to have secured tunnel between remote and local computer only but also between one remote and many local computers with more certificates? Every local computer should have own certificate.

stunnel through httpd
by Chatty 07 Jun '09

07 Jun '09

Hello, I've got the crazy idea to run stunnel behind an existing, SSL-enabled, basic-auth-using httpd. Configuration would be as follows: 1. put some stunnel.cgi into /usr/www/cgi-bin which would call stunnel binary 2. start stunnel client with -r https://login:[email protected]/cgi-bin/stunnel.cgi Advantages (assumed you're behind a proxy which allows only 443 as outgoing port): a. You can still access other WebIFs on that server. b. You don't have to administer another web server including authentication, certificates and so on. May be stunnel is not the best tool for the above scenario (I reckon stunnel is currently unable to fulfill this)... I hope someone can shed some light on this. Cheers, Chatty.

1 server and more desktops
by aaa aaa 07 Jun '09

07 Jun '09

Hello, I have one server and 3 desktops (PC1,PC2,PC3). I need to do this: every pc should communicate with server with his own certificate and server should sends anwser back to the computer encrypted for this one pc only.

Hello guys, I would like to secure my OpenBSD/FreeBSD for communication over stunnel only. How should I configure BSD and stunnel when I want allow comminucation with one server only (data from pc encrypted with server's public certificate and allow data from this server to my pc encrypted with pc's public key) and drop all other communication (all other ports and certificates)? thank you, mia ---------- Sutaz s InPage o ceny za viac ako 2000 Euro.

Re: [stunnel-users] Stunnel for secure email connections
by Lee 25 May '09

25 May '09

Thanks again, Guy, I appreciate your efforts there. So I don't have to do anything regarding certificates or digital signatures, or anything along those lines? I just install OpenSSL and Stunnel, configure stunnel.conf, tweak Thunderbird's accounts settings and Avast's ports, and go with it? Guy wrote: > So what you have to do to proxy the connections through Avast! I don't > know, you'll need to show. > Do you *really* need to scan your outbound connections? > This whole thing is more of a challenge / experiment than anything else. Certainly, scanning my SMTP connection(s) is far from important. Off this specific Stunnel issue but related:- For the last day or so, I've gone back to my 'old' setup of TB + Popfile + Avast, and I've noticed that emails from my 'secure' POP connections are actually being scanned by Avast. They probably have been for some time and I didn't notice, but only recently have I turned on the 'adding of notes' in Avast's email scanner which adds an email footer along the lines of 'Avast found this message to be clean'. I assume this scanning of 'secure' emails is a convenient byproduct somehow or other of routing the secure connections through Popfile. For reference, Popfile is listening on its default port of 110, and the Avast email scanner currently also only has port 110 in its POP redirected ports settings. Thunderbird has the host for those accounts as 127.0.0.1, also on port 110, and the username is in the form of: pop_server:username:ssl which Popfile requires. The :ssl is required by Popfile to handle secure connections. I do notice that non-secure connections' emails end up with the scanning footer being added twice, suggesting Avast is double scanning them. Secure connections' emails only get the one footer added. So all told, all incoming email seems to be scanned by Avast, albeit some of it twice. > Your stunnel configuration file has 2 [popmail] service names, that > will be confusing. And why do you have a [popmail] and [pop3_sky] > connecting to the same MTA? > That is because I don't know what I'm doing :) I originally built stunnel.conf without catering for Popfile, then I wanted to introduce Popfile into the equation, so I found the below advice page regarding Popfile and Stunnel :- http://getpopfile.org/docs/howtos:stunnel It appears I wrongly guessed how to interpret that advice on what to add to stunnel.conf I have since had some clarification on this from a query I raised on this at the Popfile forums:- http://getpopfile.org/discussion/1/188 > Did you enable debugging within stunnel? > > Global options: > > debug = debug > output = stunnel.log > Yes, I did try that, and dabbled a little with the packet sniffers. However I didn't find it any easier to pinpoint what was actually going on regarding the prescence or otherwise of a secure connection. ie I don't know what I'm looking at/for. At the moment, my only method of 'testing' what is 'probably' going on, is to open or close parts of my local chain, and thereby build an apparent picture of what is happening. My original doubts of 'am I actually achieving a secure connection using Stunnel and my local chain' are not grounded in anything; I am/was just wanting to somehow avoid just assuming I had set everything up properly.

Hello Guy and thanks for your reply. Guy wrote: > So you have... > Client (MUA) <=> Avast and/or Popfile <=> Stunnel <=> Server (MTA) > > > Yes, that's right. I've looked at the mail headers more, and tried some of the packet sniffing/log methods, but I'm not really having any more success in understanding / pinpointing a secure connection. I think I'm not going to be able to grasp the issues here, so maybe it is simpler if I could simply state what I have done, to check that it should be correct; I installed both OpenSLL and Stunnel. I haven't changed anything from the OpenSLL install. In stunnel.conf, I currently have the file shown at the bottom of this email. I have changed settings in Thunderbird's mail accounts (hosts and ports) and in Avast Anti-Virus email scanner. (its redirected ports settings) Adding Popfile (a local mail 'tagging' proxy) back into the equation has required some further tweaks to Thunderbird's ports and server usernames syntax. As I said earlier, all seems to be working, in that my 'chain' appears to be having an effect. However should I be considering anything else to make this process meaningful, such as certificates or security issues? My only motive for using Stunnel and OpenSSL is to allow Avast email scanner to scan _all_ emails, including those it normally cannot scan due to their servers requiring me to use a secure connection. So, if I am doing this 'new' process wrongly or opening up security issues due to not understanding it, I would be better off reverting to how it was previously, seeing as the mail servers I use state they do virus scanning anyway. Thanks again, Lee UK my current stunnel.conf :- client=yes service=popmail [popmail] accept = 127.0.0.1:210 connect = pop.mail.yahoo.co.uk:995 [popmail] accept = 127.0.0.1:310 connect = pop.tools.sky.com:995 [pop3_sky] accept = 127.0.0.1:1109 connect = pop.tools.sky.com:995 [pop3_yahoo] accept = 127.0.0.1:1108 connect = pop.mail.yahoo.co.uk:995 [smtp_sky] accept=127.0.0.1:259 connect=smtp.tools.sky.com:465 [smtp_yahoo] accept=127.0.0.1:258 connect=smtp.mail.yahoo.co.uk:465 [imap_sky] accept=127.0.0.1:1439 connect=imap.tools.sky.com:993 -------------------------------------------------------------------------- --- avast!

Stunnel for secure email connections; email headers ?
by Lee 23 May '09

23 May '09

Hello, I have been dabbling with Stunnel in order to do the following: Connect with remote POP3, IMAP and SMTP servers using a secure connection; Path those connections on my Windows XP desktop pc through Avast Anti-Virus and/or Popfile to Mozilla Thunderbird. After much fiddling and grinding of my rusty mental muscles, I appear to have everything working and pathing properly. However I am not confident and some amount of luck has been involved in settling on the apparently correct pathing, ports settings and stunnel.conf So, my question here is; Can I look for anything in the email headers to verify that I am actually achieving a locally made secure connection using Stunnel? Or, if necessary, can I force something into the headers to show this? As I imply, results/clues suggest all is in place correctly, but part of me doesn't really believe I have actually done it. :) Thanks very much, Lee UK --- avast! Antivirus: Outbound message clean.

Multiple SSL Versions
by Jeremy 21 May '09

21 May '09

Hi, Is there any way to make the sslVersion version take multiple options? I would like to restrict things to TLSv1 or SSLv3 but it seems only one option can be specified. I tried specifying this in the cipher section instead of ALL but couldn't seem to get it to work. Also here is something a little weird I've noticed, if anyone else has ran into it before and knows what's going on. With sites set to use TLSv1, sometimes while testing a HTTPS site using Firefox SSL (when both SSLv3 and TLSv1 is enabled in Firefox) sometimes the site won't come up. It feels like Firefox is using a weird SSL version to do the SSL certificate verification but once you trust the certificate it uses the right settings. I've set sslVersion = all, and trusted the SSL certificate in Firefox, then set sslVersion = TLSv1 again and I can get to the site ok at that point. Kind of weird. I'm probably just going to have to leave sslVersion = all, but Nessus and other security scans really like things locked down to just TLSv1 or SSLv3. stunnel: LOG5[17972:3086609296]: https-site01 accepted connection from 1.2.3.4:50878 stunnel: LOG3[17972:3086609296]: SSL_accept: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number stunnel: LOG5[17972:3086609296]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket

Preventing "choose a digital certificate" pop-up in IE
by Wallace Winfrey 08 May '09

08 May '09

Hello I have browsed the archives but have not found the answer to this question... I have stunnel set up to handle https connections. It sits on a CentOS server alongside HAProxy and works fine with every browser except for Internet Explorer. When I connect with Internet Explorer, I get a blank "Please choose a digital certificate" pop-up. I am pretty sure I have a configuration issue. Here's what I have: socket=l:TCP_NODELAY=1 socket=r:TCP_NODELAY=1 options = NO_SSLv2 ciphers=ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM output = /var/log/stunnel.log [my.host.name] accept=my.external.IP:443 connect=127.0.0.1:8101 xforwardedfor=yes CAfile=/etc/stunnel/GlobalSign.pem cert=/etc/stunnel/my.host.name.pem verify=1 How do we turn off the request for the client certificate in IE? Here are my details....thanks in advance. w * stunnel-4.15-2.el5.1 * I am running it standalone: /usr/sbin/stunnel /etc/stunnel/stunnel.conf * /usr/sbin/stunnel -version stunnel 4.15 on i686-pc-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 Auth:LIBWRAP Global options debug = 5 pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none * uname -a: Linux my.host.name 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux * glibc version is 2.5-34 * gcc is not installed, using CentOS RPM * OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

patch: TCP keep-alive socket options
by Ludolf Holzheid 08 May '09

08 May '09

Dear list, the attached patch allows for tweaking the TCP keep-alive socket options on Linux 2.4 and later. Thanks to the groundwork laid by Michal, this got fairly trivial. We use this to keep NAT table entries alive for connections that are expected to have idle periods longer than the NAT time-outs of the routers in involved.

Odd termination of stunnel process...
by Robert Nickel 07 May '09

07 May '09

We've been happily using stunnel for quite some time now and have run into a strange problem. At seemingly random intervals, stunnel just freaks out an dies. I don't know if it's getting overwhelmed or what but I'm not seeing anything in the logs for stunnel or any other process. Any help is appreciated. Stunnel is being used to wrap a service that was written without use of the ssl libraries directly and connects to two remote web servers (that happen to be running on the same host, separate ports). Config information: OS: CentOS 5.1 OpenSSL: 0.9.8b stunnel -version: stunnel 4.15 on i686-redhat-linux-gnu with OpenSSL 0.9.8b 04 May 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH key = /etc/stunnel/stunnel.pem session = 300 seconds TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none Config file contents:

[PATCH] Fix undefined aliasing in libwrap.c
by Miloslav Trmac 02 May '09

02 May '09

Hello, The attached patch changes the code not to access a part of a char[...] array using an int *, which is undefined in ISO C. Using memcpy() is safe. I would have posted it on in the BTS, but it doesn't allow me even to log in... Thank you, Mirek

I was trying to get stunnel working with anonymous ciphers (SSL_DH_anon_WITH_RC4_MD5_128, etc.) from a java based client and found that s_server succeeded while stunnel failed with the "no shared ciphers" message because it has routines to initialize a temporary DH key in the absence of a certificate. Here's a sloppy patch that just borrows those routines from the s_server source code. This is against an older version of stunnel (RHEL4u7 based system), but the latest version also fails without similar patching.

aNULL ciphers
by Brian P Hinz 20 Apr '09

20 Apr '09

Hi, Does stunnel support the use of the aNULL cipher suites? I can't seem to make it work, stunnel just fails with a "no shared ciphers" message. I don't think that the problem is with openssl or the client, since when I test it with s_server the handshake completes. Thanks, -brian

Issue resolving path to .conf using DFS and changing from "by name" to "by IP address"
by Peterson, Stephen 17 Apr '09

17 Apr '09

We use stunnel 4.20 and encountered a problem today and hope someone may be able to provide some insight to a solution. Our client machines are all Windows XP machines with stunnel started as a service. Those installs of stunnel have the path to the .conf as part of the path to the executable. The path to the .conf uses a DFS share. Our network administrator changed our DFS share from "by name" to "by IP address" and then the client services could not resolve the location of the .conf file when the services started on the next start up of client machines. Has anyone encountered this before and what did you do to fix it? Thanks for any assistance. Stephen

error during multithreaded operation
by Dale Kingsbury 13 Apr '09

13 Apr '09

OS: Windows 2003 SP2 SDK: 2003 R2 SDK We have a multithreaded application that uses a REST-style interface to an SSL-enabled UNIX box that only uses AES. I tried using WinHTTP, but unfortunately, AES is broken in the 2003 version of WinHTTP (confirmed by M$). SO, I hook up stunnel, which works fine when I only start one thread, but if I use more than 1 thread, I get the following error in the stunnel.log. Note that the error is on thread 7140, and the connection is immediately closed. I have retry logic that re-starts failed threads, and the restarted thread works the second time. (of course, the first has finished, so it is essentially running by itself.) The other item of interest is that each thread is sending about 500,000 bytes of data in chunks of 16,000 bytes, and my trace shows that it usually fails after having written more than 100,000 bytes successfully. Any suggestions or help would be greatly appreciated... 2009.04.10 13:17:01 LOG7[3016:7040]: SSL state (connect): SSLv3 flush data 2009.04.10 13:17:01 LOG7[3016:7140]: SSL alert (write): fatal: decrypt error <<<<< ----- NOTE FAILS HERE ON thread 7140 2009.04.10 13:17:01 LOG7[3016:7040]: SSL state (connect): SSLv3 read finished A 2009.04.10 13:17:01 LOG7[3016:7040]: 0 items in the session cache 2009.04.10 13:17:01 LOG7[3016:7040]: 20 client connects (SSL_connect()) 2009.04.10 13:17:01 LOG7[3016:7040]: 19 client connects that finished 2009.04.10 13:17:01 LOG7[3016:7040]: 0 client renegotiations requested 2009.04.10 13:17:01 LOG7[3016:7040]: 0 server connects (SSL_accept()) 2009.04.10 13:17:01 LOG7[3016:7040]: 0 server connects that finished 2009.04.10 13:17:01 LOG7[3016:7040]: 0 server renegotiations requested 2009.04.10 13:17:01 LOG7[3016:7040]: 0 session cache hits 2009.04.10 13:17:01 LOG7[3016:7040]: 0 session cache misses 2009.04.10 13:17:01 LOG7[3016:7040]: 0 session cache timeouts 2009.04.10 13:17:01 LOG6[3016:7040]: SSL connected: new session negotiated 2009.04.10 13:17:01 LOG6[3016:7040]: Negotiated ciphers: AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 2009.04.10 13:17:01 LOG3[3016:7140]: SSL_connect: 1408C095: error:1408C095:SSL routines:SSL3_GET_FINISHED:digest check failed 2009.04.10 13:17:01 LOG5[3016:7140]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2009.04.10 13:17:01 LOG7[3016:7140]: bycast-write-1 finished (1 left) Configuratation file: ;Stunnel configuration for Acuo. ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ; Use it for client mode client=yes verify=0 ; Service-level configuration [bycast-read-1] accept = 18080 connect = 10.220.8.100:8080 ;ciphers=AES128-SHA:AES256-SHA TIMEOUTclose = 0 sslVersion = TLSv1 Dale Kingsbury Founder - Lead Software Engineer Phone: 651-744-9225 << NOTE new number Fax: 651-730-4231 Cel: 651-592-5204 email: dale(a)acuotech.com <mailto:[email protected]> RSNA Booth #4980

With OpenSSL so widely used it is constantly being evaluated for vulnerabilities. When they're found, it is patched quickly but dependent applications are sometimes slow to incorporate patched versions. Thanks again for your excellent help. ./Cal

OpenSSL Vulnerabilities
by Cal Webster 07 Apr '09

07 Apr '09

Will there be a security update of stunnel to address vulnerabilities outlined in CVE-2009-0590, CVE-2009-0591, and CVE-2009-0789? Alternatively, will stunnel use updated OpenSSL libraries on the host? It appears that this is true on Fedora RPM packages. For Example: ldd stunnel: ------------ libssl.so.7 => /lib64/libssl.so.7 (0x0000000006a3c000) libcrypto.so.7 => /lib64/libcrypto.so.7 (0x0000000007954000) ------------ rpm -q --requires stunnel ----------------------------------------- ... libcrypto.so.7 ... libssl.so.7 ... ----------------------------------------- rpm -ql openssl | egrep 'libcrypto.so.7|libssl.so.7' ----------------------------------------- /lib/libcrypto.so.7 /lib/libssl.so.7 ----------------------------------------- However, I don't know how to determine whether the same dependency works with Win32 dll's. For example, could we install "Win32 OpenSSL v0.9.8k Light" from the below link to resolve the vulnerabilities? http://www.slproweb.com/download/Win32OpenSSL_Light-0_9_8k.exe The description says that it "Installs the most commonly used essentials of Win32 OpenSSL v0.9.8k" but it doesn't say exactly what. Thanks for any insights or suggestions. Cal Webster

It's not really a bug. It's rather an inherent property of chrooted environments. They often require some files and/or devices to work properly. Pozdrowienia z Polski, Mike

Updating OpenSSL used by stunnel
by Peter Droop 06 Apr '09

06 Apr '09

Hi, I am running stunnel 4.25 with openssl 0.9.8h on Windows 2003 Server. There are some security updates out for openssl, that are not available on stunnel.org. Can I update openssl by just replacing libeay32.dll and libssl32.dll in the stunnel installation directory? I downloaded the dlls from http://www.slproweb.com/products/Win32OpenSSL.html. Thanks, Peter

GPL patches
by Michal Trojnara 01 Apr '09

01 Apr '09

Dear Users, I've just uploaded some patches sent to stunnel-users list over the years to ftp://stunnel.mirt.net/stunnel/contrib/. Please remember my policy is *not* to include any GPL code into the official stunnel distribution. If you're brave you're free to apply the patches yourself, or even create a fork of stunnel with some additional functionality. Just be aware there were already some security vulnerabilities (including remote code execution) discovered in the 3rd party stunnel patches. For this reason I also don't recommend stunnel package/port maintainers to include any 3rd party code with stunnel. Best regards, Mike

Can't get NTLM authentication to work with proxy connect.

Hi there, My stunnel client is on an Active Directory-authenticated XP workstation, which needs to connect via a web proxy that authenticates using NTLM. I populated my login details in protocolUsername and protocolPassword, but the connection just dies when it reaches the proxy server.

Is there any specific format that I need to use when using the protocol* settings for NTLM? Thanks and regards.

stunnel 4.26 MS SQL connetion - works on Vista, not on XP
by zervakos 25 Mar '09

25 Mar '09

Greetings, I was wondering if anyone's come across anything like this. I want to encrypt connections for MS SQL Server 2008 Express from a Windows XP client to a Windows 2003 Server. Following these instructions: http://www.securityfocus.com/infocus/1677 I was able to configure encrypted connections by pointing SQL Server Management Studio to 127.0.0.1 on _either_ XP or Vista and then that gets tunneled over to the Windows 2003 Server running SQL Server 2008 Express. I can browse the database tables, etc. Now the problem. I have users that make use of a thin client that connects directly to the SQL Server. It has one config file that I've pointed to 127.0.0.1. When I run this thin client on Vista, it works great, however, when running it on XP, stunnel tries to connect, but then gives up after several attempts. Here's what I see in the server log before connecting: 2009.03.23 12:26:59 LOG7[284564:274684]: RAND_status claims sufficient entropy for the PRNG 2009.03.23 12:26:59 LOG7[284564:274684]: PRNG seeded

Re: [stunnel-users] Using stunnel in a box having http client and http server.
by Joe Lau 23 Mar '09

So, my understanding is that I will need one stunnel for each remote web server that my http client is going to connnect to. For example if my http client want to connect to 3 remote web servers. I will need to setup the folllowing stunnels: Remote https Web Server #1 <------------- Stunnel #1 <---------- http client (http://localhost:81) (port 81) Remote https Web Server #1 <------------- Stunnel #2 <---------- http client (http://localhost:82) (port 82) Remote https Web Server #1 <------------- Stunnel #3 <---------- http client (http://localhost:83) (port 83) But I will need only one stunnel for my http server as follow: Remote https client #1 ------------+-----> Stunnel --------------- http server | (port 443) (port 80) Remote https client #2 ------------+ | ..... | | Remote https client #N-------------+ Is the following config file correct for my http server stunnel? client=no accept=443 connect=localhost:80 Thank you! -Joe -----Original Message----- From: Christophe Nanteuil [mailto:[email protected]] Sent: Monday, March 23, 2009 3:19 AM To: Joe Lau Cc: stunnel-users(a)mirt.net Subject: Re: [stunnel-users] Using stunnel in a box having http client and http server. 2009/3/20 Joe Lau <Jlau(a)extremenetworks.com>: > > Hello, Hello, > I am new to this list. > > I am planning to use stunnel on my box which has a http client and http server running on it. > I will need two stunnel instances, one for the http client and one for the http server respectively.

Hello, I am new to this list. I am planning to use stunnel on my box which has a http client and http server running on it. I will need two stunnel instances, one for the http client and one for the http server respectively. For my http client, my stunnel config file looks like this: client=yes accept=80 connect=remote_web_server:443 For my http server, my stunnel config file looks like this: client=no accept=443 The problem I am facing is now I have two programs (i.e. 1) stunnel for http client and 2) http server) listening to the same port 80. How do I resolve this conflict? Thank you very much for the help.

Is this possible? Stunnel FIPS mode with rdesktop to secured Microsoft terminal server
by David W Blaine 16 Mar '09

16 Mar '09

Hi list, I was wondering if this solution is possible? Linux Linux Windows Server 2003 rdesktop ----> Stunnel client ------> Terminal Server no enc FIPS mode FIPS mode I know there is doco's about how to setup a Stunnel using client and server setups on either side but Windows admins here are unlikely to install Stunnel on their side. They have enabled FIPS mode on their Windows servers and disconnected all the Linux/UNIX admins from their Terminal Server. So I was wondering if I could get away with a client only solution? Dave

persistent SSL connection
by Dorai Ashok 16 Mar '09

16 Mar '09

Hi all, I was able to setup stunnel between two hosts successfully but the only problem I am facing is that, the SSL connection between the two hosts is not persistent. For every connection I make to the stunnel client, a new SSL connection is established by the stunnel client to the stunnel server. Is there a configuration variable in stunnel which can make the SSL connection between stunnel client and server persistent ? Thanks, -Dorai.

Unless, of course, you are trying to communicate with a third-party product that speaks SSL - if either the client or the server is not under your control, there's no way to make them use multiplexed SSH connections instead of SSL :) But if it's just stunnel on both sides, then yes, SSH tunneling may be a better choice for multiplexing, although it has its own problems - most often related to connection keepalive, especially if there is some kind of firewalling gateway on the path.

Re: [stunnel-users] Configuring stunnel to use p12 and p7b in client mode
by Eduard Witteveen 14 Mar '09

14 Mar '09

Pierre and List, Thanks for the answer. Maybe i wasn't clear enough in my question: 1 - I have a p12 and p7b file, which work in firefox and iexplore. 2 - I want to setup a tunnel, so the encryption is done by stunnel and not by the browser(so i can 'talk' normal http for soap) Removing the password sounds like a good idea, so i started with this. However, somehow my openssl doesnt know the command pkey.

Can stunnel do this?
by Miguel Beccari 13 Mar '09

13 Mar '09

I tried this configuration: client = yes debug = debug cert =/Users/etc/stunnel/stunnel.pem [imaps] accept = localhost:143 delay = yes connect = remote:993 and it worked! But if I change "accept = localhost:143" to "accept = localhost:993" it does not work. I need a imaps proxy. Logs does not say anything interesting (SSL accepted: new session negotiated) Thank you all, Miguel

Newbie Question - Moving stunnel to another machine
by Dave Nasralla 13 Mar '09

13 Mar '09

Hi, I'm pretty new to the unix command line and stunnel. I am running Mac OS 10.5 with the latest version of stunnel. I was able to get stunnel up and running on my computer and it is working fine ( - I installed X-Cold, used Darwinports, got it compiled and configured, and launching at bootup). My question is: If I have an identical Machine (same hardware and OS), is there an easy way to move stunnel over to it? I copied the stunnel executable and the configuration file over to the new machine. I ran it from the terminal command line. % /Applications/stunnel /Applications/stunnel.conf The original location on my machine was (/opt/local/bin/stunnel /opt/ local/etc/stunnel/stunnel.conf) No errors (got the prompt back). But no services start on the configured ports. Am I missing support files? Or am I being dumb to think you can simply copy the program over. I was hoping to not have to jump through the same hoops to get it up and running. Any direction would be appreciated. Thanks, dave naz PS It is a simple configuration to help non SSL Mail clients connect to GMail - no certs involved.

Configuring stunnel to use p12 and p7b in client mode
by Eduard Witteveen 10 Mar '09

10 Mar '09

Hello, I'm trying to get stunnel running on my local system, so it will connect to the remote a host, which requires authentication with this p12 file(with password). I also have the chain of trust which is in the p7b file. The reason why i want to do this, is that the remote host exposes a soap interface by https, and i think it would be a good idea to tunnel the communications with stunnel, so a transparant configuration can be used. Also, this would mean there is no configuration needed for the browser anymore, since it can connect to the localhost instead of to the remoteserver. I've tested the p12(certificate PKCS12?) and (trust chain PKCS7?) files with internet explorer and firefox. They work(i can browse the remotehost), but i still have to enter the password. I've converted the p12 and p7b files into dem files with the following commands: > openssl pkcs12 -in certificate.p12 -out certificate.pem > Enter Import Password: > MAC verified OKK > Enter PEM pass phrase: > Verifying - Enter PEM pass phrase firefox: store as PEM with chain chain.p7b --> chain.pem Config: > key=certificate.pem > CAfile=chain.pem > client=yes > debug=7 > output=stunnel.log > verify=1 > [http] > accept=80 > connect=www.remoteserver.com:443 > TIMEOUTclose=0 Command: > sudo /usr/bin/stunnel4 stunnel.conf Error: > 009.03.11 00:58:10 LOG5[30424:3082909360]: Threading:PTHREAD > SSL:ENGINE > Sockets:POLL,IPv6 Auth:LIBWRAP > 2009.03.11 00:58:10 LOG6[30424:3082909360]: file ulimit = 1024 (can be > changed with 'ulimit -n') > 2009.03.11 00:58:10 LOG6[30424:3082909360]: poll() used - no > FD_SETSIZE > limit for file descriptors > 2009.03.11 00:58:10 LOG5[30424:3082909360]: 500 clients allowed > 2009.03.11 00:58:10 LOG7[30424:3082909360]: FD 10 in non-blocking mode > 2009.03.11 00:58:10 LOG7[30424:3082909360]: FD 11 in non-blocking mode > 2009.03.11 00:58:10 LOG7[30424:3082909360]: FD 12 in non-blocking mode > 2009.03.11 00:58:10 LOG7[30424:3082909360]: SO_REUSEADDR option set on > accept socket > 2009.03.11 00:58:10 LOG7[30424:3082909360]: http bound to 0.0.0.0:80 > 2009.03.11 00:58:10 LOG7[30430:3082909360]: Created pid file > /var/run/stunnel4.pid > > 2009.03.11 00:58:20 LOG7[30430:3082909360]: http accepted FD=13 from > 127.0.0.1:59793 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: http started > 2009.03.11 00:58:20 LOG7[30430:3082738576]: FD 13 in non-blocking mode > 2009.03.11 00:58:20 LOG7[30430:3082738576]: Waiting for a libwrap > process > 2009.03.11 00:58:20 LOG7[30430:3082738576]: Acquired libwrap process > #0 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: Releasing libwrap process > #0 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: Released libwrap process > #0 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: http permitted by libwrap > from > 127.0.0.1:59793 > 2009.03.11 00:58:20 LOG5[30430:3082738576]: http accepted connection > from > 127.0.0.1:59793 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: FD 14 in non-blocking mode > 2009.03.11 00:58:20 LOG7[30430:3082738576]: http connecting > ${REMOTESERVER_IP}:443 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: connect_wait: waiting 10 > seconds > 2009.03.11 00:58:20 LOG7[30430:3082738576]: connect_wait: connected > 2009.03.11 00:58:20 LOG5[30430:3082738576]: http connected remote > server > from 10.0.2.15:38710 > 2009.03.11 00:58:20 LOG7[30430:3082738576]: Remote FD=14 initialized > 2009.03.11 00:58:20 LOG7[30430:3082738576]: SSL state (connect): > before/connect initialization > 2009.03.11 00:58:20 LOG7[30430:3082738576]: SSL state (connect): SSLv3 > write > client hello A > 2009.03.11 00:58:20 LOG7[30430:3082738576]: SSL state (connect): SSLv3 > read > server hello A > 2009.03.11 00:58:20 LOG4[30430:3082738576]: VERIFY ERROR: depth=0, > error=unable to get local issuer certificate: ${UNIQUE NAME} > 2009.03.11 00:58:20 LOG7[30430:3082738576]: SSL alert (write): fatal: > bad > certificate > 2009.03.11 00:58:20 LOG3[30430:3082738576]: SSL_connect: 14090086: > error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate > verify > failed > 2009.03.11 00:58:20 LOG5[30430:3082738576]: Connection reset: 0 bytes > sent > to SSL, 0 bytes sent to socket > 2009.03.11 00:58:20 LOG7[30430:3082738576]: http finished (0 left) (${UNIQUE NAME} / ${REMOTESERVER_IP} were replaced) Tested by connecting the browser to http://127.0.0.1:80/ How can i get stunnel to redirect http://127.0.0.1:80/ to http://remoteserver:443/ and use the certificate and chain to validate the connection?

Stunnel 4.26 compile issue against openssl 0.9.8j + openssl-fips-1.2
by David W Blaine 10 Mar '09

10 Mar '09

Hi all, When I compile against OpenSSL 0.9.8j + OpenSSL-FIPS-1.2 module on Centos 4.7, I get an error in client.c: client.o(.text+0x1dd): In function `init_ssl': /tmp/stunnel-4.27/src/client.c:333: undefined reference to `FIPS_set_prng_key' collect2: ld returned 1 exit status make[1]: *** [stunnel] Error 1 make[1]: Leaving directory `/tmp/stunnel-4.27/src' make: *** [all-recursive] Error 1 It seems this call is related to a bug in OpenSSL-FIPS-1.1.1 module according to the comments. Checking the references in the includes for both OpenSSL 0.9.8j and OpenSSL-FIPS-1.2, I found that the call should be "fips_set_prng_key" with 3 arguments (the above requires only 2). So based on the comments, I removed it and I was able to successfully compile and install. Not sure if that is the right thing to do??? Dave

email through clients where no port number defined - like Outlook Express
by Richard Brust 06 Mar '09

06 Mar '09

A few days ago, sent an email in regards to a CRM program attempting to access GMail where no port number definitions are possible. That email (or part of it) is below, but after a bit more diag, I found that the email client was communicating with stunnel, but was not getting past that to GMail (or stunnel was not getting to GMail, not sure how to tell). I also realized that the settings of this application are similar to Outlook Express - email server defined, but no ability to specify port number. Does anyone have stunnel working with Outlook Express? I have a feeling the stunnel settings for that would be similar to what I need. Thanks, and the original email is below I am attempting to send/receive to GMail through a CRM program (contains email client) called ACT! (http://www.act.com) ACT! only allows server addresses in the program configuration, NOT port numbers. (e.g. smtp.gmail.com or 127.0.0.1 - nothing else) I have configured stunnel 4.26 as such: ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [pop] accept = localhost:110 connect = pop.gmail.com:995 [smtp] accept = localhost:25 connect = smtp.gmail.com:465 and in ACT as such: SMTP as localhost POP as localhost (also have tried 127.0.0.1, but with no difference).

Stunnel for tunneling all traffic (vpn)
by BS TLC 06 Mar '09

06 Mar '09

Is it possible to create 2 virtual interfaces, for tunnelling all traffic (vpn)? With ssh program it's quite simple: with the -w option 2 new (tunnel) interfaces are created (for example tun0 and tun1), and it's possible to create a vpn for all type of traffic.

stunnel with libwrap does not disconnect from terminal
by Lars Kruse 02 Mar '09

02 Mar '09

Hi, starting with v4.21, stunnel does not disconnect from the terminal anymore. This can cause problems, if the caller does not redirect stdout/stderr to /dev/null. This did not happen with v4.20. The problem disappears, when I use he "--disable-libwrap" configure switch when compiling stunnel. I am running debian testing on i386 with the stunnel4 package 4.22-2. How to reproduce: 1) stunnel config file: setuid = lars pid = /tmp/stunnel.pid [server] connect = 8080 accept = 443 cert = /some/file 2) command line: cat stunnel.conf | stunnel4 -fd 0 3) process list: erker:~/ttt/stunnel/testing/stunnel-4.26# ps -ef| grep stun lars 29599 1 0 13:47 pts/1 00:00:00 src/stunnel -fd 0 lars 29600 1 0 13:47 pts/1 00:00:00 src/stunnel -fd 0 lars 29601 1 0 13:47 pts/1 00:00:00 src/stunnel -fd 0 lars 29602 1 0 13:47 pts/1 00:00:00 src/stunnel -fd 0 lars 29603 1 0 13:47 pts/1 00:00:00 src/stunnel -fd 0 lars 29604 1 0 13:47 ? 00:00:00 src/stunnel -fd 0 4) FDs of spawned processes: erker:~/ttt/stunnel/testing/stunnel-4.26# ls -l /proc/29599/fd lrwx------ 1 root root 64 Jan 10 13:50 1 -> /dev/pts/1 lrwx------ 1 root root 64 Jan 10 13:47 2 -> /dev/pts/1 lrwx------ 1 root root 64 Jan 10 13:50 3 -> socket:[903037] Is this the expected behaviour? I use stunnel in one of my projects (http://cryptonas.org) and it started to hang with v4.22. After redirecting stdout/stderr to /dev/null, the program works again. I assume, that stunnel should take care for stdout/stderr on its own, when started in daemon mode, right? thanks for your great work! Lars

No Tray Icon in XP SP3
by Zepp 01 Mar '09

01 Mar '09

Hi all: I am running Stunnel 4.26 in Windows XP SP3. The issue I'm having is that the tray icon is missing when I install and run Stunnel as a service. the program works fine, and it shows up on the process list okay, but no tray icon appears at all. I scanned the help file and saw an option called taskbar which is supposed to be toggled on by default. I added it to the conf file anyway, and it didn't make any difference. The only way I've been able to get the icon to show is to start Stunnel by adding a shortcut to the Startup folder. Is there an option I'm missing? Thanks much! Zepp

Stunnel error
by Reinier van der Gugten 23 Feb '09

23 Feb '09

Hi, I use the STunnel tool to connect to my Ms-SQL database. And so far this works nice. However at one organization I have the following problem: << connect_wait: s_poll_wait timeout>> And the connection fails. Here is the log file and config file. Can you give me any hints how to check where it goes wrong? Thanks.

stunnel hanging (libwrap)
by Ulrich Wisser 11 Feb '09

11 Feb '09

Hi, on my current project I have a strange error. Stunnel will work for months and suddenly stop accepting connections. At other times it will fail after a couple of hours. It doesn't crash. Connections are still accepted, but no SSL negotiation does take place. Please find a log below. It seems to be some problem with libwrap. As you can see in the logs the last usage of libwrap doesn't release libwrap properly. "Released libwrap process" log statement is missing. And after that just everything hangs waiting for libwrap. But why is this happening? Our host.allow and host.deny files are empty. libwrap is supposed to allow everything. Any suggestions are welcome!

stunnel client connecting to host with dynamic dns service
by Adamson H 09 Feb '09

09 Feb '09

Hi, stunnel 4.26 solves a number of issues running on FreeBSD. However, a stunnel client still has a problem reconnecting to a host with dynamic DNS service after the host IP has changed. Stunnel client seems unaware of the host update, pointing the dynamic DNS name to the old outdated IP. In order to get reconnected to the host, I have to create a cron script to detect the IP change and restart stunnel on the stunnel client. My client conf file has the following: [1873] accept = 1873 connect = hostname.dynaip.org:1873 The ip of hostname.dynaip.org changes at a random interval. Please help. Adamosn H

Your understanding is not correct, but similar functionality was re-implemented from scratch. You may consider Reading The Fine Manual at: http://stunnel.mirt.net/static/stunnel.html The relevant part is: protocol = proto application protocol to negotiate SSL currently supported: cifs, connect, imap, nntp, pop3, smtp protocolAuthentication = auth_type authentication type for protocol negotiations currently supported: basic, NTLM Currently authentication type only applies to 'connect' protocol. default: basic protocolHost = host:port destination address for protocol negotiations protocolPassword = password password for protocol negotiations protocolUsername = username username for protocol negotiations Best regards, Mike

Hi, I use Stunnel for some of my customers. However I tried it myself (after a while, and after a reinstall of windows) and I get this error. Can anyone tell me how to get it to work again? I get the same error when I run it as administrator, or when I change the port from 443 to 4430. 2009.02.04 13:54:04 LOG7[2828:5668]: Snagged 64 random bytes from C:/.rnd 2009.02.04 13:54:04 LOG7[2828:5668]: Wrote 1024 new random bytes to C:/.rnd 2009.02.04 13:54:04 LOG7[2828:5668]: RAND_status claims sufficient entropy for the PRNG 2009.02.04 13:54:04 LOG7[2828:5668]: PRNG seeded successfully 2009.02.04 13:54:04 LOG7[2828:5668]: Certificate: stunnel.pem 2009.02.04 13:54:04 LOG7[2828:5668]: Certificate loaded 2009.02.04 13:54:04 LOG7[2828:5668]: Key file: stunnel.pem 2009.02.04 13:54:04 LOG7[2828:5668]: Private key loaded 2009.02.04 13:54:04 LOG7[2828:5668]: SSL context initialized for service SQLServer 2009.02.04 13:54:04 LOG5[2828:5668]: stunnel 4.26 on x86-pc-mingw32-gnu with OpenSSL 0.9.8i 15 Sep 2008 2009.02.04 13:54:04 LOG5[2828:5668]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2009.02.04 13:54:04 LOG5[2828:5672]: No limit detected for the number of clients 2009.02.04 13:54:04 LOG7[2828:5672]: FD 224 in non-blocking mode 2009.02.04 13:54:04 LOG7[2828:5672]: SO_REUSEADDR option set on accept socket 2009.02.04 13:54:04 LOG3[2828:5672]: Error binding SQLServer to 127.0.0.1:31433 2009.02.04 13:54:04 LOG3[2828:5672]: bind: Permission denied (WSAEACCES) (10013) 2009.02.04 13:54:04 LOG3[2828:5672]: Server is down My stunnel.conf looks like this (actual IP address has been modified): ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting debug = 7 ;output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [SQLServer] accept = 127.0.0.1:31433 connect = 85.15.135.121:443 ; In case of a proxy server, use: ;connect = 10.3.2.50:8080 ;protocol = connect ;protocolHost = 85.15.135.121:443

crl next update field functionality seems incorrect
by Steve Hoffman 04 Feb '09

04 Feb '09

Regarding this piece of code in verify.c: if(X509_cmp_current_time(next_update)<0) { s_log(LOG_WARNING, "Found CRL is expired - " "revoking all certificates until you get updated CRL"); X509_STORE_CTX_set_error(callback_ctx, X509_V_ERR_CRL_HAS_EXPIRED); X509_OBJECT_free_contents(&obj); return 0; /* reject connection */ } I don't believe this is correct functionality. The "next update" field is not an expiration of the CRL, but more of an indicator that you, as the holder of the CRL, should obtain a new one. Snippet from this link: http://www.netscape.ca/browser/netscape8/help/en/ssl_help.html#next_update About the "Next Update" Date The browser uses the CRLs it has available to check the validity of certificates issued by the corresponding CAs. If a certificate is listed as revoked, the browser won't accept it as evidence of identity. A CA typically publishes an updated CRL at regular intervals. Every CRL includes a date, specified in the Next Update field, by which the CA will publish the next update of that CRL. In general, if the date in the Next Update field is earlier than the current date, you should obtain the most recent version of the CRL. To view CRL information and set up automatic CRL updating, see Viewing and Managing CRLs. CAs are required to produce a new CRL by the Next Update date. However, the absence of the most recent CRL does not by itself invalidate a certificate. For this reason, if the most recent CRL is not available, a certificate may be validated even though the most recent CRL shows it as expired. Automatic CRL updating can help to avoid this situation. I'd like to suggest removing this check. Thanks, Steve

Fwd: Stunnel & Zimbra
by Allen 02 Feb '09

02 Feb '09

Hi folks, I'm reposting this from my email address on file, because it was initially rejected (I think because I sent it from my main business address, which is not the address I have listed with this group. My apologies. ------------ I've been using stunnel with Zimbra, on OS X Sever since last year and it's been working well (SSL tunnels should be seen and not heard ;-). I upgraded Zimbra yesterday to a new version, that apparently was supposed to fix its instability running on the OS X platform. However, the upgrade wound up breaking the mail server's ability to send email. From Zimbra's web client, it appears like mail is getting sent (there's a little green sent mail box that pops up right after you click on the send button). Mail never arrives at the client end. I can still receive mail into the Zimbra account when I send to it from my business or personal email account. I provisoned and reloaded posffix, etc., and still can't receive mail on the other end. No stunnel settings have changed since before the upgrade. Here are the stunnel-related file outputs: ----------------------------------------------------------------- root# cat /opt/local/etc/stunnel/stunnel.conf client = yes foreground = no [smtps] accept = 5000 connect = server_name.x.y.com:465 (server name changed to protect the innocent ;-) ----------------------------------------------------------------- cat /opt/zimbra/conf/relay_password server_name.domain.com [email protected]:fakepassword --------------------------------------------- With the real usernames, password, domains, etc., those two (above) stunnel files worked perfectly well with stunnel, and sending mail was not a problem. That was --until I upgraded Zimbra. I realize that this is a stunnel forum and the Zimbra-related forum deals with all their issues. However, I'm wondering if somebody out there in stunnel land might have a light bulb going off regarding this issue. Perhaps there's something that I'm overlooking? Thanks! Allen

Identification Propagation patch using stunnel client certificates
by Christophe Nanteuil 02 Feb '09

02 Feb '09

Hello, NB : this patch is provided as alpha version : it handles only 1 request at a time for each administrative and ident servers. Why to use this patch ? This patch can be useful when : - you provide access to Internet via your stunnel server and when your legislation enforces you to keep logs of who connected where and when. In this case, you will have Squid logs filled with identification of stunnel clients in a very simple way : nothing to ask to the client as it uses automatically its certificate to fill in the identity fields. - you want to implement several profile access for your clients accessing your web proxy/server : as the proxy will ask ident request to stunnel, you can create filter groups to allow / denied access (with redirection to a page that you can customize) depending on stunnel answer : see filtergroups option of DansGuardian or acl options in squid. Patch to version : 4.26 Type : new feature Description : Identification Propagation using stunnel client certificates The patch proposes to extend the identification propagation provided by the directive 'EXEC=' to directive 'CONNECT=' when using client certificates. With EXEC directive, Subject name and Issuer Name of clients are put in environment variables, which allows the program to determine identity of the stunnel client. This patch adds an ident server functionality to stunnel, compliant with RFC 1413, to allow propagation of identification to remote hosts specified by the service directive 'CONNECT='. Additionnaly, this patch provides an admnistrative server "bound" to the Ident server : on the administrative socket (default port 127.0.0.1:790), you can request number of users currently connected and list them. How to use this patch ? You just have to add a 'identServer=yes' directive to services that you want to propagate identification. For example, you can use this patch when connecting to a DansGuardian web proxy (installed on proxy.example.com) with the option authplugin = '/etc/dansguardian/ authplugins/ident.conf' enabled in the configuration file (or when connecting to a Squid web proxy compiled with --enable-ident-lookups option), and the following stunnel configuration file (located in /etc/ssl/stunnel/stunnel-ident.conf) : ... [WEB] accept=8080 connect=proxy.example.com:8080 identServer=yes ... Stunnel will create a listening socket on 0.0.0.0:113 and answer requests initiated by DansGuardian. -- Christophe Nanteuil

Feature request: set environment variable for inetd-type program
by Michael Renner 27 Jan '09

27 Jan '09

Moin, I am not a programmer, I am a writer and user, so I have to ask kindly for a additional stunnel feature I need the ability to push some information from the stunnel client side to the server side. To be more concrete: a self written script that is called by stunnels 'exec' statement need some settings, e.g. username and password. My idea is to configure this in the client side stunnel.conf and pass this as a environment variable to this script. There is no chance to pack these stings in a client certificate, because everybody who is able to handle snoop/tcpdump will be able to read this. I imagine a configuration like this: client stunnel.conf [foo] accept = 127.0.0.1:1234 connect = 192.0.20.0:443 env = "SUSER=renner" env = "SPASS=geheim" server stunnel.conf [foo] accept = 192.0.20.0:443 exec = /opt/foo/script.sh env = yes My question to the developers: do you think this is a helpful feature, also for others? Greetings -- |Michael Renner E-mail: michael.renner(a)gmx.de | |D-81541 Munich Germany ICQ: #112280325 | |Germany Don't drink as root! ESC:wq

Use stunnel through firewall for home Web server?
by Bill Eldridge 25 Jan '09

25 Jan '09

I was interested in whether there's a simple way to have stunnel redirect traffic from a public Web browser/port to my home Web browser behind my DSL firewall (no ports opened/forwarded for incoming connections on the router, only outgoing-initiated) I scanned old posts but didn't find anything that quite fit - references are usually for people who want to get out from behind a firewall, not publish sites publicly from behind (i.e. externally initiated clicks)

Hi everyone I try to compile stunnel, but it fails. Actually, it tells me about a parse error inside signal.h, and i think it's a falsePositive.

0x09 bytes in stunnel-4.26/src/Makefile.am
by Andrew Schulman 14 Jan '09

14 Jan '09

For some strange reason, there are five hex 09 bytes in stunnel-4.26/src/Makefile.am. This broke my Cygwin build: I remove the Windows-only stuff from this file for Cygwin, and diff captured the 0x09 characters that got removed, but then when I later tried to apply the patch, patch choked on them. It seems that each of these bytes should really be 0x0A. Strange. Andrew.

One problem I have found in doing this is that if socketpair(2) is used to create the file descriptor that will be connected to stunnel's stdio, then stunnel's libwrap checking is activated because it detects it to be a socket. Using socketpair is a nice way to turn a TCP client into one that connects via a two-way pipe with stunnel (because the client app doesn't have to special case the two file descriptors for stunnel's stdin and stdout when reading and writing.) Since a user (i.e. not a sysadmin) has no control over the libwrap settings in /etc, stunnel's libwrap check will always fail when used this way. In my opinion, stunnel should allow disabling of libwrap (and syslog too) via the config file (i.e. not just compile time options). This makes the "one connection" client usage you describe work better. Karl

Re: [stunnel-users] How do I do a one-time client connection?
by D. Richard Hipp 13 Jan '09

13 Jan '09

Perhaps I spoke too soon about having solved my own problem. Suppose I have a configuration file (test.conf) like this: client=yes connect=www.fossil-scm.org:443 Then if I run: stunnel test.conf And I type "GET / HTTP/1.0" on standard input, the webpage comes back on standard output. So far so good. But if I do: stunnel test.conf <test.in >test.out Where file test.in contains the "GET / HTTP/1.0" test, I get nothing back! I also tried this: cat test.in | stunnel test.conf And various combinations of this: openssl s_client -connect www.fossil-scm.org:443 <test.in In every case, when I type the GET line on standard input it works. When I redirect from a file it does not. Any hints on the cause of the very unexpected and very mysterious behavior? D. Richard Hipp drh(a)hwaci.com

How do I do a one-time client connection?
by D. Richard Hipp 13 Jan '09

13 Jan '09

I'd like to invoke stunnel to handle a single SSL client-side connection (talking to an SSL server) with the assurance that the stunnel quit will automatically quit after that one connection closes. I did not see any options to support this. Did I overlook something, or is stunnel just not able to do this? D. Richard Hipp drh(a)hwaci.com

public domain [PATCH] to stunnel 4.27b1 for Windows CE / Windows Mobile compilation and unicode bug fixes
by Pierre DELAAGE 10 Jan '09

10 Jan '09

Dear Sir, Please find enclosed a patch in "diff -cr orig work" format, applying to stunnel4.27b1 as found here ftp://stunnel.mirt.net/stunnel/. This patch maily addresses compilation and unicode issues for Windows CE targets. I use MS EVC 4sp2 compiler with WCE 420 SDK, on a vista host platform. Once debugged the code works fine on WM5 and WM6 HTC smartphones. It needs a windows CE openssl lib (I logged a patch to openssl snap 20090102 because it has some compilation issues on windows CE platform). * For the sake of completeness openssl 098i and 098j (latest) must be ALSO patched to compile for wince, with this patch I submitted to openssl team : http://marc.info/?l=openssl-dev&m=123099015013538&w=2 The present stunnel patch addresses the following issues : 1/ COMPILATION FAILURE : on common.h "EINVAL redefinition" : in fact the compile options WX (see evc.mak) does not tolerate any warning : to avoid a warning on EINVAL redef, we must protect this undef by ifdef. Note that there is still a problem : if the symbol is NOT defined at all, it will NEVER be defined by that revised code : this is because the compiler always generate an error if it sees something like : #ifdef EINVAL #undef EINVAL #define EINVAL WSAEINVAL #else #define EINVAL WSAEINVAL #endif because it seems to not like two defines even separated by a else. Just putting the #define outside of a block dealing with undef, does not solve the compilation issue. 2/ COMPILATION FAILURE : related to wcecompat/setjmp.h SOLUTION : in evc.mak, needed /D ARM to compile with wcecompat/setjmp.h. This symbol is not documented in MSDN but clearly present is header files. Moreover It is consistent with other processor symbols described in the sdk. 3/ COMPILATION FAILURE : related to gui.c pb with undeclared hmainmenu identifier, because "endif use_win32" misplaced. 3/ RC COMPILATION FAILURE : related to resources.rc CAUSE : "VERSION" unknown SOLUTION : /dversion in rflags in evc.mak 4/ LINK ERROR : fatal error LNK1181: cannot open input file 'libeay32.lib' cause : bad path name in evc.mak for openssl lib. since openssl >> 098a (eg 098h) "out32dll" folder is named "out32dll_targetCPU". 5/ LINK ERROR on gui.obj : error LNK2001: unresolved external symbol _beginthread _$(TARGETCPU) Cause : in sthreads.c, misplaced "#endif os2" Note : corrected various erroneous comments on #if endif in sthreads.c ************* OPERATIONAL ERRORS (at run-time) using stunnel to enable certificate based authentication for POPS/SMPTPS between a smartphone and a linux server, I faced this problems : When first trying to authenticate a dlgbox is displayed on the smartphone to input the password of the private key protecting the client certificate: 6/ RUN-TIME ERROR : "squares" displayed instead of chars in "password input dialog box" titlebar Well, this is only a cosmetic issue, but this is still an issue. Cause : this is a typical unicode issue in gui.c pass_proc/wm_initdialog : the sendmessage to display the title uses a concatenation of two strings : a constant extracted from the resource file, and converted to wchar by TEXT macro in unicode context, and a key file name given by ui_data->section->key. The problem is that the file name is always of type 8bit char, leading to concatenation "scrambling" when concatenated with a unicode string. SOLUTION : it seems not possible to change the type of ui_data->section->key to tchar/wchar because it is used in various ansi code. So the simplest way to correct this pb is just to make a local conversion from ansi to tchar in gui.c/pass_proc/initdialog 7/ RUN-TIME ERROR : It is impossible to validate a password on a private key protecting a certificate: The password is ALWAYS rejected (after many tests with 3 retries). Cause : the password is input as unicode (because the message EM_GETLINE on the control IDE_PASSEDIT is unicode ready) but stored and managed as an ansi string so the password can never be validated. NOTE : contrary to the documentation of windows CE sdk, the EM_GETLINE msg IS REALLY unicode ready. Indeed this is also the case in classic win32 sdk for PC platform (described in the msdn library). SOLUTION : the input password must be converted to ansi before being validated vs openssl 2009.01.05 13:00:01 LOG3[4849170:5712826]: Wrong pass phrase: retrying 2009.01.05 13:00:05 LOG3[4849170:5712826]: error stack: 140B3009 : error:140B3009:SSL routines:SSL_CTX_use_RSAPrivateKey_file:PEM lib 2009.01.05 13:00:05 LOG3[4849170:5712826]: error stack: 906A065 : error:0906A065:PEM routines:PEM_do_header:bad decrypt 2009.01.05 13:00:05 LOG3[4849170:5712826]: SSL_CTX_use_RSAPrivateKey_file: 6065064: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt 2009.01.05 13:00:05 LOG3[4849170:5712826]: Server is down I hope you will find this patch useful. Thank you for your excellent work, Yours sincerely and happy new year, Pierre Delaage Note : I use stunnel to establish a simple "vpn" between smartphones and a corporate linux server mainly for HTTPS/POPS/SMTPS support. Stunnel is very relevant in that matter, over solutions based on SSH (although we use also ssh), from a communication cost point of view : ssh establishes permanent socket between client and server, so that the communication is charged by the mobile network provider : and these charges are very expensive. On the contrary stunnel only establishes ssl sockets on demand so that financial charges are limited to strict necessary. Please note that stunnel brings "client based certificate authentication" to POP/SMTP mobile mail user agents which only supports SSL with server authentication, but NO client authentication, such as mobile outlook.Here again stunnel is very relevant. Note 2 : the unicode bug fixes should benefit also to the win32 stunnel version for PC. Note 3 : this mail has also been sent to webmaster(a)stunnel.org, but with no response at all.

However: it should appear > harmless to others, just like a webserver. > Behind this should work a proxy server (squid).

Squid documentation will tell you what is the need for the home-made authentification program. I think it's easier with DansGuardian proxy : - In stunnel config file : select pertinent fields of the certiificate : only Issuer_CN -> identFields=32 - in /etc/dansguardian/dansguardian.conf, create 2 groups : filtergroups = 2 filtergroupslist = '/etc/dansguardian/lists/filtergroupslist' - create filter groups in /etc/dansguardian/lists/filtergroupslist. (All not matching users will go in group 1) : put a line like "your issuer CN equals 2" - in /etc/dansguardian/dansguardianf1.conf, put "groupmode=0" , ie banned - in /etc/dansguardian/dansguardianf2.conf, put "groupmode=2" , ie non filtered Note that the authentification of the users is done by stunnel. Stunnel forwards the identification to the proxy which does not need to authenticate since it was done by stunnel. If the ident provided by my patch is not convenient, you can modify it to match your needs. Hope this helps -- Christophe Nanteuil

Hi, [...] > But this setup is senseless, since the DN is readable with a network sniffer. > It does not appear harmless any longer after a closer look into the network > traffic. But it have to. > Now, I need an other idea to implement such s service. One easy solution that comes to mind is to deploy an outer SSL tunnel for privacy and then set up an inner SSL tunnel for traffic separation. However, I think this would require stunnel on the client side as well, at least for legitimate users. Cheers, Toby. -- begin LOVE-LETTER-FOR-YOU.txt.vbs I am a signature virus.

Stunnel (v4.26) Running, Working, but Sometimes Aborting
by Jeff Salisbury 08 Jan '09

08 Jan '09

Greetings, We are new to stunnel. We've installed Stunnel v4.26 on a handful of Windows XP machines, and we can send and receive emails through the Stunnel configuration. These XP machines reboot automatically every night. Many mornings, when the user sits down and tries to initially send email, the email hangs and Stunnel aborts (or has already aborted). If the user runs stunnel again, our sending and receiving of email is restored and stunnel seems rock-solid for the rest of the day. Has anybody else had stability problems with Stunnel v4.26? Any suggestions? FYI, relevant configuration information is shown below: Best regards, Jeff ================================== 1) Instead of installing stunnel on each machine, we have copied the following files into a network folder available to everyone in our office: Q:\bin\stunnel\stunnel.exe Q:\bin\stunnel\Q:\ibeay32.dll Q:\bin\stunnel\libssl32.dll Q:\bin\stunnel\stunnel.conf 2) Everyone has a shortcut installed in their "Startup" folder to run Q:\bin\stunnel\stunnel.exe. 3) Here is our stunnel.conf file: # GLOBAL OPTIONS client = yes output = C:\Documents and Settings\All Users\Application Data\stunnel-log.txt debug = 0 taskbar = yes # SERVICE-LEVEL OPTIONS [pop3] accept=995 connect=mail.ourpop.com:995 [smtp] accept=465 connect=mail.oursmtp.com:465

Distinguished Name (DN) is a cleartext network communication?
by Michael Renner 07 Jan '09

07 Jan '09

Moin, I am confused. Trying to use the DN as a kind of password replacement I saw that the DN goes unencrypted through the network, while the traffic itself is encrypted of cause. Analysing the network packages with wireshark I get this: 100104083828Z0..1.0...U....DE1.0...U....Germany1.0 ..U....Munich1.0...U. ..vbox4php1.0...U....stunnel1.0...U....mars.mtr.mynet1$0"..*.H.. .....michael.renner(a)gmx.de0.."0 This is, more or less, the content of the DN. Is there a chance to encrypt this? My setup should work, no matter if a client certificate exists or not (also independent of the DN's content) . But the appliation behind stunnel (started by stunnel using the 'exec' statement) may behave dependent on the DN! Any chance?

Stunnel New User
by David Aitchison 07 Jan '09

07 Jan '09

Hello, I have a potential use for Stunnel on a project I am working on. Excuse the perhaps very silly questions, this is all new to me. I have read through the manual, and understand that Stunnel can either be run from the command line ad-hoc or as an application using the stunnel.conf configuration file. If I have Stunnel running on the server, does this mean that all mails that leave that server will be SSL encrypted? I have a requirement to send mails out over SSL, but my application doesn't support that, it does support sending out over standard SMTP port 25, but I need it to use port 465? Thanks in advance, David Aitchison

hiding a proxy that appear like a web server?
by Michael Renner 03 Jan '09

03 Jan '09

Moin, I want to use stunnel (in conjunction with prtunnel) to reach my own proxy server out of a restricted network. The normal stunnel connection works so far without a problem. But I am looking for a possibility that this connection (reaching the endpoint of stunnel with my proxy server behind) appears like a normal webserver (maybe with just one simple index.html) to others. Any ideas? Thanks -- |Michael Renner E-mail: michael.renner(a)gmx.de | |D-81541 Munich Germany ICQ: #112280325 | |Germany Don't drink as root! ESC:wq

Problem with the client certificate
by Michael Renner 27 Dec '08

27 Dec '08

Moin, it seems that I understood something wrong with stunnel client certificates. First of all: until now I run stunnel 4.18 and stunnel 4.21 with debian and kubuntu without client certificates (with success). I use it to reach a proprietary application through an untrusted network. Now, I want the clients to authenticate against the server. Therefor, as a quick and dirty test, I used the same stunnel.pem file at the server and at the client side. The configuration at the server side (where the application is waiting for connections, in this example it is just a script) looks like this: cert = /etc/stunnel/stunnel.pem #chroot = /var/run/stunnel/ pid = /tmp/stunnel.pid setuid = nobody setgid = nogroup output = /var/log/stunnel4.log exec = /root/stest.sh verify = 1 [BreakOut] accept = 192.168.0.1:443 Here is the configuration at the client side, where a browser establish a connection cert = /etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem sslVersion = SSLv3 chroot = /var/lib/stunnel4/ setuid = stunnel4 setgid = stunnel4 pid = /stunnel4.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 verify = 0 debug = 7 output = /var/log/stunnel4/stunnel.log client = yes [BreakOut] accept = 127.0.0.1:8080 connect = 192.168.0.1:443 First of all: is it right to set 'verify = 1' at the server side, and 'verify = 0' at the client side? It seems right to me, because the client should authenticate, but not the other way. Anyhow: As soon as a connection is opened using this configuration it will terminate at the same second. renner@mars:~$ telnet localhost 8080 Trying 127.0.0.1... Connected to localhost.

Windows binary kits on 64 bit 2003 server or 2008 server
by Rich Jordan 24 Dec '08

24 Dec '08

Sorry to sully the list with wintel questions, but I haven't been able to locate an answer, and without systems available to test the obvious method of finding out is not available. We're running Stunnel V4.26 on a windows 2003 32-bit server, communicating with several better platforms running Stunnel V4.20 and newer, no issues. One interested customer is running windows 2003 server, 64-bit, and plans on moving to win2008 server 64 bit in the not too distant future. I do not have access to either OS/system and they're reluctant to install without knowing ahead of time what might happen. I'm hoping someone has tried the current STunnel binary kit on either or both of those systems. Will the kit run on 64-bit windows 2003, and is it usable on windows 2008? If not is this a situation where a build from source on either/both of those windows systems will produce working code? I've also found a number of hits for reputed OpenSSL ports for 64 bit windows. Any particular ones known to be good? Thanks for any info. Rich Illuc ivi, illud feci

Log rotation patch
by Christophe Nanteuil 17 Dec '08

17 Dec '08

Hello, NB : I propose this patch in alpha version. It has been tested only on a Linux Mandriva. (in the alpha version, it's recommended to use it on logs you might loose). Why to use this patch ? One reason I have to restart periodically stunnel is to do log rotation. This patch allows log rotation while running stunnel by implementing it directly inside. Therefore, the established connections are not closed by log rotation. Patch to version : 4.26 (should work on earlier versions). Type : new feature Description : Log rotation inside stunnel How to use this patch ? 3 new options are added in config file (see manual) maxLogSize : maximum size of log file (output option in config file). If logs have to be added, a log rotation is initiated. maxLogFiles : how many log files you want to keep. Default 7. useLogCompression : specify if rotated log files kept must be compressed or not. (requires zlib to be set). Just recompile stunnel after applying patch in stunnel directory: patch -p1 < /path/to/stunnel-logrot-0.10a.patch Test results are welcomed. Regards -- Christophe Nanteuil

Not sure if ranting will get you the kind of answer that you look for but it was certainly entertaining for me. Anyway... I agree, some times things can be a little frustraiting but I guess that depends on how much time on how much work you want to put into it. Sorry to hear you feel stupid. Everyone has to start from 0 at shome point and it takes time to get a good handle to how things work. The question is... do you really want to know how things work or just want them to work without having to do much? A google search of "SSL Explained" http://wildbill.nulldevice.net/presentations/sslpreso/ I liked slide 11/35 nice little diagram of SSL handshake wich helps to visualize in very general terms how an SSL connection works. The rest of the slides are good too check them out! In your particular case that forced you to change from plain-text to SSL connections to your mail server. You had a couple of options. - First and most obvious is to use SSL support build into your mail client (Thunderbird, Outlook,etc) most if not all modern mail clients support SSL natively. No need for stunnel there. - If your mail client does not support SSL then stunnel is the way to go. But your issue is on how stunnel is being used. As client. When you are a client... you always want to verify your server. You want to make sure you are connected to the right server. You want to use verify=2 in stunnel.conf How do we verify that the server I just connected is in fact the right server? That is the Certificate Authority's job. We ultimately have to trust the CA they issued the certificate for the server owner. They signed the certificate with their key. and we use the CA's certificate to verify that signature. Here is the catch... operating systems, and some programs are shipped with a prebuild collection of CA certificates. Unfortunatelly stunnel does not. However, most CAs let you download their certificates for your own use. In your particular case, looks like the server you are connecting to uses a certificate issued by Equifax Secure Certificate Authority Here they have the download page for the CA Certificates. http://www.geotrust.com/resources/root-certificates/ You pointed out that they refuse connections if the client presents a certificate. Yes, that is somehow a common practice. Mutual authentication (both server and client send certificates to each other and verify them) is impractical in some cases.

Extending stunnels connect functionality
by bernhard.czech＠nobiscum.de 24 Nov '08

24 Nov '08

Hi all, we are looking for somebody to extend stunnel's multiple connect functionality a bit as of: - adding the ability to send a configurable string to each "connect" and compare the answer against an configured expectation string - the expectation should also be able to be interpreted as an regular expression. - the testing interval should be configurable - an alternative port should be configurable - it should be possible to call a script instead of doing a connection with the connect string provided as a parameter. - a way of monitoring might all paths might be good (i.e. writing a status file on regular basis) These things are pretty much the same things that LVS ( http://www.linuxvirtualserver.org/) provides. But we would like to reduce the complexity in our environment a bit. If somebody is interested to implement this feel free to contact me. If possible with an amount of expected reward.

Tunnel traffic from a network interface

Hi! Is it possible to capture traffic from one network interface on one computer, tunnel it to a second computer by stunnel and then send it through a network interface on that computer? This without changing any data on the network traffic (MAC adresses, IP etc). Thanks for any answers! greetings, Kjetil

Amount of FD's per connection
by Koornstra, Reinoud 21 Nov '08

21 Nov '08

Hi, I am using stunnel compiled to use threads. I read in the faq that a connection may use 1 to 4 fd's per connection. Normally this is only one, how can I influence this, I mean making sure there is one fd per connection? I also wish to limit the amount of max connections at the same time. Perhaps the most easy way is limit the amount of fd's per process with ulimit. However, depending on how many fd's are needed per connection it is difficult to set right now. Kind Regards, Reinoud.

Proxy support in configuration file?

Is there proxy support for Stunnel, and if so, how do I specify the proxy server in the configuration file? If it is not supported, can you give me a price estimate on what it would cost to add it? Greetings, Reinier. E.g. I want to connect to an external location at: Myserver.com:443 The proxy is at: CustomerProxy:8080 And my application runs at the customer talking to: localhost:1433 The proxy does not require authentication. Looking at the docuemtation you linked me I found this example: CONNECT server.example.com:80 HTTP/1.1 Host: server.example.com:80 Proxy-Authorization: basic aGVsbG86d29ybGQ= Using my addresses, where goes what?

stunnel and expiring CRLs
by Jason Haar 19 Nov '08

19 Nov '08

Hi there Is stunnel capable of re-reading updated CRLs on the fly? Without needing to be restarted? I have tried both CRLfile and CRLpath (with the hashes) with no luck. It appear stunnel only reads them on startup and never refers to them again? There also seems to be no option to send a HUP or the like to force a re-read - only a full restart will make stunnel re-read the CRLs. i.e. our system works after a fresh restart until the original CRL expires, and then stunnel starts rejecting new connections with "Found CRL is expired - revoking all certificates until you get updated CRL" - even though there have been several CRL file (and hash) updates in between. Restarting stunnel makes it start working again. I've googled around and see several other people have asked similar questions over the years, and there are references by Michal Trojnara that it should work? This is stunnel-4.14-2 under CentOS5 with openssl-0.9.8b-8.3.el5_0.2. No chroot jail Thanks! -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.

With stunnel 4.26 (or ealier), in order to verify revocation of clients' certificates, I use this configuration file : -------------------8<------------------ CAfile=/etc/ssl/stunnel/ca_certs.pem CRLfile=/etc/ssl/stunnel/crl.pem cert=/etc/ssl/stunnel/server.pem key=/etc/ssl/stunnel/server.key sslVersion=TLSv1 verify=2 [WEB] accept=8080 connect=127.0.0.1:3128 ------------------->8------------------ 1/ If there is no CRLfile when stunnel starts, stunnel dies and logs show "Failed to load /etc/ssl/stunnel/crl.pem revocation lookup file" -> ok. 2/ If the CRLfile is correct, stunnel starts. When the CRL expires, stunnel rejects any new connection. Logs then show : " Found CRL is expired - revoking all certificates until you get updated CRL" -> ok 3/ If the CRLfile is not a valid CRL, stunnel starts and ignores the CRLfile. Then, for any new connection, logs show "CRL: verification passed". -> NOT ok, IMO. examples of wrong CRLs : a CRL issued by an unknown CA or a certificate in the PEM format. This can happen when the CRL expires (soon) and the administrator puts a "new one" but misfits files. He then restarts stunnel, which works. This behaviour can be annoying because the logs of CRL are now in level 6 (INFO) and not any more in level 5 (NOTICE). My configuration was in debug=5 and logs showed only "CRL: verification passed", I could not determine what CRL was really used. I propose the attached patch to modify behaviour in case 3/, ie if no CRL corresponding to the issuer of each certificate of the chain is found : - reject connection if CRLdir or CRLfile was specified in the config file - accept connection but warn in logs if the use of CRL was not explicitly set in the config file. NB : the source code of function "crl_check" shows "/* based on BSD-style licensed code of mod_ssl */". I looked into the code of "mod_ssl-2.8.31-1.3.41" (file pkg.sslmod/ssl_engine_kernel.c, line 1601-1769) and there is actually the same behaviour. -- Christophe Nanteuil

Spawning a shell
by Tobias Dussa 29 Oct '08

29 Oct '08

Hi everybody, maybe I'm missing something real obvious here, but I can't figure out what's going wrong. I'm trying to make stunnel spawn a regular shell when it gets a connect. As far as I understand, the pty option should allocate a virtual tty, so I ought to be able to just exec() a shell. However, this won't work; apparently some more magic is required. I do get the basic interactive functionality to work (i. e., I can enter, say, ls and get back a directory listing), but the terminal won't work properly: Unwanted echoes (stty -echo doesn't help). Furthermore, for some reason stderr is not connected to the new pty but sticks to stunnel's original pty. I have tried spawning a shell directly from stunnel (with exec), spawning a script which redirects stdin/-out/-err to the proper pty, then execs a shell, spawning a script which execs login, spawning a script which execs getty. (The latter being closest to what I want, but not good enough.) I'm running out of ideas. Anyone ever did this? Any comments? (Incidentally, if anyone has a better idea how to create the possibility to log in with an X.509 certificate without using stunnel, I'm all ears.) I'm running stunnel4 on Debian etch: --- stunnel 4.18 on i486-pc-linux-gnu with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/run/stunnel4.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH key = /etc/stunnel/stunnel.pem session = 300 seconds sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none --- Cheers, Toby. -- The nine most terrifying words in the English language are: I'm from the government and I'm here to help. ---Ronald Reagan

Thanks for solving my problem!
by editor 20 Oct '08

Hi: Thanks! I commented out the "Verify" option within the configuration file and restarted the application. I can use it POP3S & HTTPS with the Nokia & Sony-Ericsson mobiles fine now as well as Thunderbird. I will check with Outlook next. Window's mobile is complaining it can not create a SSL session however. I think it has to do with the public certificate I use in the mail host. Godaddy uses this two part public certificate and the Network Solutions is a single file. I am hoping in a new release of Stunnel, it can support a two part public certificate. Thanks again!!!

Version 4.26 and using to secure IMAPS & POP3
by Editor (Kevin) 19 Oct '08

19 Oct '08

Hi: I upgraded to the current 4.26 as I was having an issue with 4.15. The idea is to secure IMAP traffic as well as inbound SMTP. The email client is the latest Thunderbird and seems to be very stable. The mail Host is a Sun E-250 with current patches for Solaris 9. Note: I am using a public certificate and as it from "godaddy.com", it is this unusual two part certificate. This may be where the problem is as I had to combine the two public certificate files together (maybe the next version of STUNNEL could do this automatically so the risk of errors is reduced!). However, using STUNNEL, I am having an issue connecting as I get a strange error message and the connection dies.

Assume currently I retrieve my emails from my mailbox unencrypted with the following info: pop3.mydomain.com port=110 Now I want to switch to an encrypted POP3 mail connection. with the following information pop3.mydomain.com port=777 Can I simply write now in the conf file: [myownsetup] accept = 127.0.0.1:110 connect = pop3.mydomain.com:777 Is this sufficient?

Question (new user!) how to get it to work? - SQL
by Reinier van der Gugten 10 Oct '08

10 Oct '08

Hi, I read most of the messages and tutorials, but still I do not seem to get it to work. I want to achieve the following: Client side: VB application communicating to a SQL server over port 1433. Server side: Lisning on port 1433 that is lisned to by SQL 2005. However this is not allowed evrywhere, so stunnel comes into play. Client side: VB application communicating to localhost on port 1433 Stunnel installed lisning on port 1433 and passing it on to port 80 (Note for later: I would like to use SSL, so it will pass through routers, But for the test it will suffice to keep it unencrypted. Also the server is still local and could be reached directly. But it should work fine for testing.) Server: Stunnel installed as service lisning on port 80 and transmitting it to port 1433 (later to be moved to 443, as I also run a HTTP server) The config file looks like this: ------------------------------------------------- Client: ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [SQLServer] accept = 127.0.0.1:1433 connect = 10.12.18.10:80 ------------------------------------------------- Server: ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log ; Use it for client mode ;client = yes ; Service-level configuration [SQL] accept = 80 connect = localhost:1433 ------------------------------------------------- As you can see, I tried to keep as close to the example file as I could. Looking forward to getting this to work and then to including ssl... Kind regards, Reinier.
