Stunnel compilation issue on Mac OS X 10.5 powerpc
by Cedric Lor 28 Nov '11

28 Nov '11

Hi, I've been trying to compile stunner (4.47) on a power pc Mac OS X Leopard (OS X 10.5) platform after a manual update to openssl v.1.0.0.e ggc is version 4.0.1. I run into an error according to which there would be undefined symbols in stunnel-ctx.o (see make output below). I can't figure out to which feature stunner-ctx.o is related, whether I need this feature and how to disable it in ./configure if I don't need it. Please note that I managed to install stunner 4.46 via fink on the same machine (such fink install of stunnel required installing a specific instance of openssl (v.1.0.0.0.e) within fink). Would anyone be able to identify from the make output below whether the issue comes from stunnel or from my openssl manual install? Many thanks.

stunnel & HAProxy : patch still required ?
by Thomas Manson 24 Nov '11

24 Nov '11

Hi, I'm willing to use this kind of configuration : https client -->stunnel --> haproxy --> 2 web servers in http (or more) I've understand that haproxy can't handle the ssl part, that's why stunnel is needed. I've read that a Patch is required for stunnel to work with haproxy in this kind of confirmation "I run stunnel 4.32 with patch from http://haproxy.1wt.eu/download/patches/ on port 443 and forward it to port 81 on the same machine which is bound to haproxy." Can anyone tell me if this patch is now included in stunnel, in particular, does Ubuntu 11.10 include it ? I really would rather stay with package provided by ubuntu in order to have easy upgrade/security fix. I've experiences the work overload of manually compiling everything in Apache for instance ;) Any advices on this kind of setup ? documentation pointers? best practices ?

The concept is that having non-SSL aware daemons running on your system you can easily setup them to communicate with clients over secure SSL channel. stunnel can be used to add SSL functionality to commonly used inetd daemons like POP-2, POP-3 and IMAP servers without any changes in the programs' code.

Patch: Include source IP in connection failure log lines
by Alex Gottschalk 23 Nov '11

23 Nov '11

I'm setting up an internet-facing server that will be running a service wrapped with stunnel. Given that, it made sense to me to use fail2ban to block repeat connection attempts from clients who don't have the right certificate (the system is using client-certificate authentication). Unfortunately, stunnel4 doesn't put the client source IP in connection failure log lines, so I made this quick patch to enable that. ---cut here---- --- src/client.c.orig 2011-10-05 16:47:48.000000000 -0700 +++ src/client.c 2011-10-05 16:50:37.000000000 -0700 @@ -358,10 +358,13 @@ continue; } } - if(c->opt->option.client) + if(c->opt->option.client) { sslerror("SSL_connect"); - else - sslerror("SSL_accept"); + } else { + char buf[255]; + sprintf(buf, "SSL_accept from %s ", c->accepted_address); + sslerror(buf); + } longjmp(c->err, 1); } if(SSL_session_reused(c->ssl)) { ----cut here----

Getting Stunnel to work
by Brian Miller 21 Nov '11

21 Nov '11

Hello, I recently moved my Homeseer software from web server 08 to server 08. I had stunnel working on there properly to send out e mails using a hotmail account. I downloaded the new verison of Stunnel and tried to use the same config but Stunnel was crashing. Both versions web server 08 and server 08 are 64bit. Below is the original stunnel config file that I used on web server 08, this is cashing stunnel to crash when I run it. Using the default settings works, but I need to edit the config. I'm not to smart in the whole stunnel / Homeseer side of things. I was told by the Homeseer community that I need this to use my hotmail e mail to send e mails. ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment cert = stunnel.pem ;key = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log ; Use it for client mode client = yes ; Service-level configuration [pop3s] accept = 110 connect = pop3.live.com:995 [imaps] accept = 993 connect = 143 [ssmtp] accept = 25 connect = smtp.live.com:587 protocol = smtp ;[https] ;accept = 443 ;connect = 80 ;TIMEOUTclose = 0 ; vim:ft=dosini

stunnel 4.47 released
by Michal Trojnara 20 Nov '11

20 Nov '11

Dear Users, I have released version 4.47 of stunnel. This version includes a number of important bugfixes. The ChangeLog entry: Version 4.47, 2011.11.21, urgency: MEDIUM: * Internal improvements - CVE-2010-3864 workaround improved to check runtime version of OpenSSL rather than compiled version, and to allow OpenSSL 0.x.x >= 0.9.8p. - Encoding of man page sources changed to UTF-8. * Bugfixes - Handling of socket/SSL close in transfer() function was fixed. - Logging was modified to save and restore system error codes. - Option "service" was restricted to Unix, as since stunnel 4.42 it wasn't doing anything useful on Windows platform.

expired certificate problem
by Rolf Ruediger 18 Nov '11

18 Nov '11

Hello there! Some time ago I used stunnel to send the output of a homebrew logging script to a remote server. For a few weeks now, the sever has an expired certificate, so I get an error while connecting to it. The stunnel.log looks like that: 2011.11.18 12:23:36 LOG5[753:3078719168]: stunnel 4.29 on i486-pc-linux-gnu with OpenSSL 0.9.8o 01 Jun 2010 2011.11.18 12:23:36 LOG5[753:3078719168]: Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP 2011.11.18 12:23:36 LOG5[753:3078719168]: 500 clients allowed 2011.11.18 12:24:00 LOG5[759:3078716272]: https accepted connection from 127.0.0.1:40691 2011.11.18 12:24:00 LOG5[759:3078716272]: connect_blocking: connected example.com:443 2011.11.18 12:24:00 LOG5[759:3078716272]: https connected remote server from my_outside_ip:38486 2011.11.18 12:24:00 LOG3[759:3078716272]: SSL_connect: 14094415: error:14094415:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate expired 2011.11.18 12:24:00 LOG5[759:3078716272]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket This happens, when connecting manually with "nc -v 127.0.0.1 1234" to make a http-get request. To also provide the config file of my linux client: ; Sample stunnel configuration file by Michal Trojnara 2002-2009 ; Some options used here may not be adequate for your particular configuration ; Please make sure you understand them (especially the effect of the chroot jail) ; Certificate/key is needed in server mode and optional in client mode cert = /etc/ssl/certs/https.pem ;key = /etc/ssl/certs/stunnel.pem ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = SSLv3 ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/lib/stunnel4/ setuid = stunnel4 setgid = stunnel4 ; PID is created inside the chroot jail pid = /stunnel4.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = zlib ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ; CApath is located inside chroot jail ;CApath = /certs ; It's often easier to use CAfile ;CAfile = /etc/stunnel/certs.pem ; Don't forget to c_rehash CRLpath ; CRLpath is located inside chroot jail ;CRLpath = /crls ; Alternatively you can use CRLfile ;CRLfile = /etc/stunnel/crls.pem ; Some debugging stuff useful for troubleshooting ;debug = 7 output = /var/log/stunnel4/stunnel.log ; Use it for client mode client = yes ; Service-level configuration [https] accept = 127.0.0.1:1234 connect = example.com:443 TIMEOUTclose = 0 ;[pop3s] ;accept = 995 ;connect = 110 ;[imaps] ;accept = 993 ;connect = 143 [ssmtp] accept = 465 connect = 25 ;[https] ;accept = 443 ;connect = 80 ;TIMEOUTclose = 0 ; vim:ft=dosini So, the server is not under my control, where I am logging to. Is there a problem I don't see? I thought, that when I connect to localhost, the data should be forwarded to the https-server. Thanks in advance. -Rolf
