TIMEOUTclose
by Joe Abbey 08 Apr '05

08 Apr '05

Background: I have been having issues getting Entourage to connect with my mail server over POP3S. Entourage will connect, communicate, and then hangs for 60 seconds. According to tcpdumps, Entourage appears to hang until a timeout. Connecting directly to the pop3 daemon, bypassing stunnel, there is no lag. Therefore something appears to be wrond with the stunnel/Entourage interaction. To get Entourage to work with POP3S and have virtually no lag, I've set in my stunnel.conf TIMEOUTclose = 2 for [pop3s]. Question: Is there any reason not to set TIMEOUTclose = 0? Thanks! Joe

Hi, is there a way, under win32, to have stunnel reload its .conf file and certificates without restarting the service ? (A kind of SIGHUP) Thanks, Phil

Hi, is there a way to automagically mutually verify certificates (verify=3) and to check the certificates against a .crl file hosted on a web server ? I want my "VNC over Stunnel" host check if the incoming connexions are authorized or if the certificates have expired / been revoked. Thanks, Phil

stunnel 4.09 problem: Connection rejected: too many clients
by Steven Van Acker 04 Apr '05

04 Apr '05

Hi, after upgrading to stunnel 4.09, we are having 2 problems with it that did not exist in a previous version (our case: stunnel 4.05 without pthreads) ---[ My testsetup is as follows: * stunnel listening on port 4321, connects to localhost port 13 (daytime) * daytime is enabled in inetd * stunnel was compiled without pthreads * ulimit -u = 8192 ---[ problem 1 At first, it works fine. For every incoming connection, the process forks and data is transferred. However, when the connection is closed, the forked process remains hanging for a while (about 1 minute) and then exits. This in itself is not a real problem, except that it generates a lot of processes. (and maybe causes problem 2 ?) ---[ data and logs concerning problem 1 (process hangs for 1 minute): I run the following command: openssl s_client -connect 192.168.2.119:4321 the output follows immediately The logfile (debug = debug) looks like this: 2005.03.31 14:05:05 LOG7[4552:0]: daytime accepted FD=8 from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4552:0]: FD 8 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime started 2005.03.31 14:05:05 LOG5[4553:0]: daytime connected from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): before/accept initialization 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write certificate A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server done A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client key exchange A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write change cipher spec A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: 1 items in the session cache 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects (SSL_connect()) 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 client renegotiatations requested 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects (SSL_accept()) 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 server renegotiatiations requested 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache hits 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache misses 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache timeouts 2005.03.31 14:05:05 LOG6[4553:0]: SSL accepted: new session negotiated 2005.03.31 14:05:05 LOG6[4553:0]: Negotiated ciphers: RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 2005.03.31 14:05:05 LOG7[4553:0]: FD 7 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime connecting 127.0.0.1:13 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: waiting 10 seconds 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: connected 2005.03.31 14:05:05 LOG7[4553:0]: Remote FD=7 initialized 2005.03.31 14:05:05 LOG7[4553:0]: Socket closed on read 2005.03.31 14:05:05 LOG7[4553:0]: SSL write shutdown 2005.03.31 14:05:05 LOG7[4553:0]: SSL alert (write): warning: close notify 2005.03.31 14:05:05 LOG7[4553:0]: SSL_shutdown retrying 2005.03.31 14:05:06 LOG7[4553:0]: SSL alert (read): warning: close notify 2005.03.31 14:05:06 LOG7[4553:0]: SSL closed on SSL_read 2005.03.31 14:05:06 LOG7[4553:0]: Socket write shutdown When I check netstat, the connection from the client to stunnel is in the CLOSE_WAIT state and the connection from stunnel to the daytime server is in TIME_WAIT state then 1 minute later, this follows: 2005.03.31 14:06:06 LOG6[4553:0]: s_poll_wait timeout: connection close 2005.03.31 14:06:06 LOG5[4553:0]: Connection closed: 26 bytes sent to SSL, 0 bytes sent to socket 2005.03.31 14:06:06 LOG7[4553:0]: removing pid file /stunnel.pid 2005.03.31 14:06:06 LOG7[4552:0]: Steven: going into client_status with num_clients = 1 2005.03.31 14:06:06 LOG7[4552:0]: Process 4553 finished with code 0 (0 left) Now, netstat no longer shows the connections in any state. ---[ problem 2 Another problem that was found is that after bombarding stunnel with lots of connections, it stops accepting new connections. This would be normal if all connections remained open, but they are all closed. This is the error: Mar 31 13:53:40 hostname stunnel[13044]: Connection rejected: too many clients (>=4000) netstat only shows +- 500 connections, of which none are aimed at the stunnel process in question (port 4321 in my test setup) there is only 1 stunnel process active aswell. I dug into the problem a bit and it probably has to do with num_clients not being decreased after a process is closed (although I can not find any specifics :/) greets, -- Steven

Hi! Im tying to access an internal Win2003 terminal server from my Linux box (internet). As i understand it stunnel should do the work. I have read some documents but im not sure... This is my setup. Linuxbox ----> Linuxbox ssh server | Firewall | Terminal server i wish to access. Can this be done or do i have to open a port in the fw to access the TS directly? Should stunnel.conf look like this on my linuxbox (client) cert = /usr/local/etc/stunnel/mail.pem client = yes On the TS? [TS] accept = 3000 connect = 3389 Should it have cert = ? Or could i on my linux ssh server have a config looking like this: [TS-remote] accept = 3000 connect = <internal-ip>:3389 Should it have cert = ? A novice man sends his best regards and thanks! /Kaz -- Mvh / Regards Mattias Olsson - aka - KaZaMaNIaC

Does stunnel work on Windows 2000 & SIMP(Secure Instant Messaging) ??
by DK 01 Apr '05

01 Apr '05

Hi Group, I have a windows 2000 box & want to communicate securely with someone else via SIMP(Secure Instant Messaging Protocol - http://www.winfosec.com/simp.php) I know that SIMP Instant Messaging is a "Direct Connection" & does NOT go through an intermediary server & that its encrypted, but being the security nut I am, I want to know if "stunnel" handles the SIMP protocols ? ... as I can't find anywhere what the SIMP protocols are ... because as I have read in the stunnel FAQ, stunnel does not handle UDP.

Hi Mike, Thank you for your precious help. I am using stunnel as SSL client. The SSL server runs in a router. As you suggested me, I have done these changes: at first I have modified the stunnel.conf with options = SSL_OP_TLS_BLOCK_PADDING_BUG stunnel.conf ============================== client = yes debug=7 options = SSL_OP_TLS_BLOCK_PADDING_BUG [telnet] accept = 23 connect = 10.36.3.144:4433 ============================= but I have got this error ======================================= file stunnel.conf line 5: Illegal SSL option 2005.03.31 13:26:48 LOG3[3396:3716]: Server is down ======================================= After I have changed the stunnel.conf in this way: stunnel.conf ============================== client = yes debug=7 ciphers = RC4-MD5 [telnet] accept = 23 connect = 10.36.3.144:4433 ============================== The problem I had is now solved. But my question is: how can I know more about this protocol incompatibility? Is there an accurate documentation about that and also about stunnel configuration? Sorry but sometimes it's difficult for me to find (in the FAQ or other sessions) the informations that I need. Thanks&Regards Maddalena

The IDEA algorithm is patented, but I don't think Mike included that in his builds. You can configure Stunnel to only use specific ciphers, in which case you wouldn't be using it regardless. Does that make it legal? Consult a lawyer. Software patents suck. I'd download the openssl.exe and the libs and run 'openssl.exe ciphers -v' and see exactly which ciphers it includes and avoid any from which your legal team suggess you run away. -- Brian Hatch If we aren't supposed Systems and to eat animals, why Security Engineer are they made of meat? http://www.ifokr.org/bri/ Every message PGP signed

Stunnel 4.09 released
by Michal Trojnara 26 Mar '05

26 Mar '05

New stunnel 4.09 can be found on my FTP site: ftp://stunnel.mirt.net/stunnel/ Here is the ChangeLog entry: * DLLs for OpenSSL 0.9.7f. * Bugfixes - Compilation problem with undeclarated socklen_t fixed. - TIMEOUTclose is not used when there is any data in the buffers. - Stunnel no longer relies on close_notify with SSL 2.0 connections, since SSL 2.0 protocol does not have any alerts defined. - Closing SSL socket when there is some data in SSL output buffer is detected and reported as an error. - Install/chmod race condition when installing default certificate fixed. - Stunnel no longer installs signal_handler on ignored signals.

The problem is that while I can download messages, I am unable to send e-mail because the "peer disconnects", and the log file carries the following messages: 2005.03.24 10:18:00 LOG5[2960:232]: smtp connected from 127.0.0.1:2194 2005.03.24 10:18:00 LOG5[2960:2428]: smtp connected from 127.0.0.1:2197 2005.03.24 10:18:01 LOG3[2960:232]: SSL_connect: Peer suddenly disconnected 2005.03.24 10:18:01 LOG3[2960:2428]: SSL_connect: Peer suddenly disconnected 2005.03.24 10:18:09 LOG3[2960:2084]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2005.03.24 10:18:09 LOG3[2960:3384]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number I have been able to run "openssl version" with the result: "OpenSSL 0.9.7e 25 Oct 2004" but I am unable to obtain the other outputs specified under the instructions for the "Stunnel-Users Mailing List". I have tried replacing libssl32.dll and libay32.dll with versions more recently downloaded (but with the same origination dates) and no improvement. So I am sending this message from another system running Win98 and stunnel-4.05, also using Netscape 4.6, which seems to work o.k. Please tell me how to get the right version number to work with stunnel-4.08, and WinXP. Additionally, it would be nice to know how to obtain the outputs suggested in the instructions for Stunnel-Users Mailing List.

Problems using STunnel with a non-default port - Please Help
by Chetan Rao 22 Mar '05

22 Mar '05

I have a personal webserver running on Win2K Pro SP4 that listens on port 17875. This server is accessible through my NAT and software firewall (ZoneAlarm Pro). I then installed STunnel with the following conf: [https] accept=4430 connect=17875 TIMEOUTclose=0 Now, when I access https://<server>:4430, I get a HTTP 400 (Bad Request) error message, with both Internet Explorer 6 and FireFox 1.01. However, if I change the accept port from 4430 to 443 (and make the appropriate changes on the NAT for port forwarding), and use https://<server>, it works. I don't want to use the standard port.

Certificate chain not used for server?
by Ed Kapitein 21 Mar '05

21 Mar '05

Hi all, I have a working setup of stunnel listening on port 443 and connect to the server on the same host on port 80. It is done via xinetd. Alltough everything is working just fine, clients on webbrowsers get the "you have choosen not to trust this CA" error when connecting to this server. In apache the certificate chain (bundle.ca) is used and clients connecting to the apache server wont get this error. Is there a way to make stunnel behave like apache, so the clients don't have to manually install the CA certificates? (the certificate is a vallid certificate obtained from globaslsign.be) i do have the CAfile in my options file, but this does not help. All help is greatly appreciated! Kind regards, @

Creating a man in middle attack for legit purposes.
by Todd Troutman 16 Mar '05

16 Mar '05

So I don't normally start off on a list by immediately asking a question but I've got a weird one here that's a critical thing tonight, plus, this might just be entertaining! Problem : MacOS Panther has horrible performance problems with large https web apps. So I setup Stunnel to take port 80 and run it through the web app on 443. Provides http from an https server. On a MacOS client machine I set /etc/hosts to say that system.netsuite.com, the web app, is 192.168.0.4, a handy FreeBSD 5.3 box running stunnel 4.05 It works. Sort of. Problems - the web app keeps rewriting the url from http to https, anytime I click on anything, hmmm.. so I can't make stunnel answer on 443 because then I'm back to square one. Also, I can't login, the web app is giving me a login page as http, but I get a session timeout,please login again, just repeats, unsure if something in the stunnel config should be done to fix that. Other than that, this is working. Config is currently this. client=yes accept=80 connect=system.netsuite.com:443 Anyway, so is this maybe one of the stranger uses of stunnel, possibly a wrong headed and broken way of using it, but oh well. There goes my plea for some ideas on this one, Thanks, Todd

Hi, someone could help me? I am using stunnel (4.07) as ssl client to do telnet to my router with ssl server (openssl 0.9.7d).

Radius over Stunnel??
by Frazer, Andrew non Unisys 08 Mar '05

08 Mar '05

Hello all.. I would like to pass radius over stunnel, but I'm not sure if this will work... I have a lot of 'client's that are using RADIUS for authentication, but i want to pass the data over the internet, and radius is relatively insecure. My client machines also run a web server, which stunnel sits in front of, to provide ssl encrypted web services. My radius servers can easily run stunnel, without any issue. Could someone suggest a configuration for this??

syslog question
by Brian T 04 Mar '05

04 Mar '05

If debug=4 ( or not 0 ) and output= is commented in an stunnel config, it looks like in server mode, messages goto syslog. But in client mode, nothing goes to syslog. Is this the way it's supposed to be? -Brian

Re: [stunnel-users] long delay to close the ssl session ?
by ikeda＠areabe 04 Mar '05

04 Mar '05

If TIMEOUTclose value is positive, stunnel does not transmit TCP FIN, even though application sends TCP FIN, until timeout time expires I don't know why stunnel designer chose it, maybe because of the performance, or some others. Some of the browsers do not start to display the page until receiving the entire packet. And one of the trigger for the browser to detect to receive the whole is TCP FIN. From that things, such kind of the problem of yours occurs. regards taka On Fri, 4 Mar 2005 10:39:47 -0800 (PST), gary ng <garyng2000(a)yahoo.com> wrote: > Thanks, that did the trick.

long delay to close the ssl session ?
by gary ng 04 Mar '05

04 Mar '05

Hi, I am using stunnel to wrap SSL around SWAT. Everything works fine except that it takes a very long delay for the browser to see that the page has already been transmitted completely(in other words, the other end has closed). I observed this behaviour with both 3.x and 4.x stunnel. Looking through the log, I see that it takes exactly one minute from the start of the session till the session is closed, seems to be some parameter within stunnel to hold the session. I tried both inetd as well as stand alone stunnel mode and both behave the same as well. Is this an issue with SWAT or stunnel ? If I just use plain SWAT through inetd, I don't see this behaviour. thanks for any help in advance. gary __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Anyone here managed to build stunnel for Irix? it seems socklen_t is undefined as a type on this OS (and also older versions of solaris). I have found a possible solution here: http://sprg.ssl.berkeley.edu/~fastops/ITOS/portable/socklen$_t.html but I need to know what type this identifier is supposed to be. any help?

Naive question: will stunnel connect dynamically?
by Duncan Murdoch 02 Mar '05

02 Mar '05

I currently use openssh to open a tunnel between my laptop and my POP3 server, but the tunnel keeps locking up. (I think it's a server problem, or an intermittent line problem, because it happens with both openssh and Putty.) What I'd like is a program that would open the tunnel only as needed, so I can get the mail, and let the tunnel close. Can stunnel do this? More generally, is there a quick summary somewhere on the relative benefits of stunnel's use of SSL versus an SSH approach? Duncan Murdoch

Windows XP Pro as a client of Remote Dekstop via stunnel
by Jacek Baszkiewicz 02 Mar '05

02 Mar '05

Hi! I'm currently working (without success) on such problem: I have to connect via Stunnel to Windows Server Remote Desktop from workstation with Windows XP Proffesional. When I refer to the local port handled by stunnel, Windows doesn't let me go go further, because it thinks that I'm trying to use local Remote Dekstop and prints: "You are already connected to this machine" (there can be only one connection through RD) . Is there any workaround for this problem, namely, to use secure connection via Stunnel to Remote Dekstop on XP Pro client? This is my config: client=yes cert = stunnel.pem [ts] accept=localhost:3389 connect=remote_ip:443

I'm running the stunnel as root, and netstat seems to show that it's bound to port 110, but doesn't seem to indicate any outbound connection from stunnel to our pop host after I invoke movemail. I have no idea if versions before 4.06 work; I haven't tried. Sure, this is an old OS, but zillions of other things, including the entire GNU toolchain, seem to work on it, so stunnel should, too. Builds for all three versions I've tried may be found in at the following URLs. Note that 4.07 and 4.08 fail on different files, but in essentially the same way. http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.06.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.07.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.08.build I've done some websearching, and I've searched the stunnel archives at mirt.net, but haven't found anything relevant. Any clues? Thanks...

stunnel logging problem
by Brian T 28 Feb '05

28 Feb '05

Hi, I work for a company which has a custom embedded Linux platform, and have been working with stunnel for some time but have never seen this problem. I have seen it with stunnel 4.04 and 4.07, which is compiled on a Redhat 7.2ish platform, but newer SSL libraries. (below my sig is the stunnel info). Basically I use a config file, but when debug= and output= is commented out, stunnel seems to cause a problem which resets the embedded unit. If I uncomment them both and use output=/var/log/stunnel.log ( or /dev/null ) everything works fine. Not sure where to look for the problem that is causing this since I can't even get a core dump. I looged in s_log() but nothing stuck out as being wrong. Thanks for any help you can lend, -Brian [root@JBMgateway-v63 /]# stunnel -version stunnel 4.07 on i486-pc-linux-gnu PTHREAD+POLL+IPv4+LIBWRAP with OpenSSL 0.9.7d 17 Mar 2004 Global options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /etc/stunnel/stunnel.pem pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds [root@JBMgateway-v63 /]# uname -a Linux JBMgateway-v63 2.4.20 #1729 Wed Jan 26 17:38:15 CST 2005 i486 unknown [root@JBMgateway-v63 /]# ls -al /lib/libssl.so.* -rwxr-xr-x 1 root root 210452 Jan 26 18:47 /lib/libssl.so.0.9.7 lrwxrwxrwx 1 root root 20 Jan 26 18:47 /lib/libssl.so.2 -> /lib/libssl.so.0.9.7 [root@JBMgateway-v63 /]# cat /etc/stunnel/stunnel.conf # Some debugging stuff debug = 6 output = /var/log/stunnel.log #output = /dev/null foreground = yes # Use it for client mode client = yes [SampleGroup] accept = 443 connect = x.x.x.x:6660

openssl - generating stunnel.pem - stunnel.cnf
by k-i-r＠web.de 24 Feb '05

24 Feb '05

Using Stunnel under Windows I want to create a certificate (stunnel.pem) with Openssl. According to FAQ the syntax for creating a certificate with Openssl is openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem I use openssl for windows (as part of apache-windows-http-server) . Where do I get the file stunnel.cnf ? Or is this file not necessary for creating a certificate ? Thanks for help, k.

Stunnel and configuration
by Bohdan Linda 22 Feb '05

22 Feb '05

Hi all, I have configured stunnel to do the client authetication, but I have some question. I have used following config: cert = /etc/certificates/server.pem - file with signed server cert and key (passwordless) chroot = /var/run/stunnel/ CAfile = /etc/certificates/certs -file where first item is my CA certificate followed by list of all client certificates sgined by my CA. setuid = nobody setgid = nogroup pid = /stunnel.pid verify = 3 This setup is working, but this seems to me very "unlogical". If I create for me "more logic" setup: cert = /etc/certificates/server.pem chroot = /var/run/stunnel/ CAfile = /etc/certificates/CA/cacert.pem - only certificate of my CA CRLfile = /etc/certificates/crls - only certificates signed by my CA I get the following error: 2005.02.22 15:15:10 LOG5[22418:81926]: VERIFY OK: depth=1, /C= ..... 2005.02.22 15:15:10 LOG4[22418:81926]: VERIFY ERROR ONLY MY: no cert for /C= The question is ... why? Why CAfile has to contain all client certificates, when clients certs are not CA? Why I cannot have separate file for CA and separate file for certificates that I want accept? If I do the similar setup in mod_ssl, the configuration works as expected. Anyway, I'am newbie to deploy stunnel, thus I would like to ask you for giving me you opinion of this configuration, caveats and possible enhancements. Thanks for any comments, Bohdan Linda

Hi, I am working in a project, whereas the EMS application need to be secured while communicating with NE. To make it secure, we have decided to go with stunnel and openSSL. I have following questions while using stunnel in my application: 1. I read that stunnel limits the number of clients to be connected to 125. Can I increase this number. If so, by increasing this number, what is the implication in performance of stuunel. 2. Since my EMS is capable of managing more than 1000 NEs, I would want to have multiple stunnel client running on the same workstation. Is this possible to have multiple stuunel process running on the same server. if so, how should my stunnle.conf file look like. I appreciate greatly, If I could get the answers for the above queries. Thanks and Regards, Dinesh Wipro Technologies. Bangalore.

Multiple listeners with just one instance of Stunnel?
by Michael Zarlenga 15 Feb '05

It doesn't seem possible to start 1 instance of Stunnel for multiple accept ports. Judging by the format of the Stunnel configuration file, it seems that I need to 1 instance of Stunnel for each port that accepts connections from the outside world. Is this true?
