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

20 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 03 Jan '10

03 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 24 Dec '09

24 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

Hi, there is a build problem with 4.28 on a SLES 9. May be similar to the no_ticket problem. Here is the interesting part of build log: options.c: In function `parse_ssl_option': options.c:1714: error: `SSL_OP_NO_QUERY_MTU' undeclared (first use in this function) options.c:1714: error: (Each undeclared identifier is reported only once options.c:1714: error: for each function it appears in.) options.c:1715: error: `SSL_OP_COOKIE_EXCHANGE' undeclared (first use in this function) options.c:1724: error: `SSL_OP_SINGLE_ECDH_USE' undeclared (first use in this function) make[1]: *** [options.o] Error 1 make[1]: Leaving directory `/usr/src/packages/BUILD/stunnel-4.28/src' any hints? -- Mit freundlichen Gruessen, Andreas Vetter Informations- und Kommunikationstechnik Fakultaet fuer Physik und Astronomie Universitaet Wuerzburg

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 ?

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

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. However, I have two questions: Q1: I would like to close down stunnel after sending my e-mails. How can I do that on Vista? Q2: Why do I get the following when I enter "stunnel -help" at the command line A window with the heading "Stunnel 4.27 on Win32 (not configured)" that says: Stunnel server is down due to an error. You will need to exit and correct the problem Click OK to see the error log window The error log is: Global options compression = zlib|rle compression type debug = [facility].level (e.g. daemon.info) EGD = path to Entropy Gathering Daemon socket engine = auto|engine_id engineCtrl = cmd[:arg] output = file to append log messages RNDbytes = bytes to read from random seed files RNDfile = path to file with random seed data RNDoverwrite = yes|no overwrite seed datafiles with new random data service = service name socket = a|l|r:option=value[:value] set an option on accept/local/remote socket taskbar = yes|no enable the taskbar icon Service-level options accept = [host:]port accept connections on specified host:port CApath = CA certificate directory for 'verify' option CAfile = CA certificate file for 'verify' option cert = certificate chain ciphers = list of permitted SSL ciphers client = yes|no client mode (remote service uses SSL) connect = [host:]port connect remote host:port CRLpath = CRL directory CRLfile = CRL file delay = yes|no delay DNS lookup for 'connect' option engineNum = number of engine to read the key from failover = rr|prio chose failover strategy ident = username for IDENT (RFC 1413) checking key = certificate private key local = IP address to be used as source for remote connections ocsp = OCSP server URL OCSPflag = OCSP server flags options = SSL option set an SSL option protocol = protocol to negotiate before SSL initialization currently supported: cifs, connect, nntp, pop3, smtp protocolAuthentication = authentication type for protocol negotiations protocolHost = host:port for protocol negotiations protocolPassword = password for protocol negotiations protocolUsername = username for protocol negotiations session = session cache timeout (in seconds) stack = thread stack size (in bytes) sslVersion = all|SSLv2|SSLv3|TLSv1 SSL method TIMEOUTbusy = seconds to wait for expected data TIMEOUTclose = seconds to wait for close_notify (set to 0 for buggy MSIE) TIMEOUTconnect = seconds to connect remote host TIMEOUTidle = seconds to keep an idle connection verify = level of peer certificate verification level 1 - verify peer certificate if present level 2 - require valid peer certificate always level 3 - verify peer with locally installed certificate 2009.11.11 13:03:36 LOG3[5440:5128]: Server is down

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 ?
by anders nilsson 05 Nov '09

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…

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 23 Oct '09

23 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 20 Oct '09

20 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!

Re: [stunnel-users] rewrite Destination: when rewriting Host:
by Brian Hatch 07 Oct '09

07 Oct '09

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 01 Oct '09

01 Oct '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

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 02 Sep '09

02 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 12 Aug '09

12 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 14 Jul '09

14 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 23 Jun '09

23 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 22 May '09

22 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 08 May '09

08 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.
