Username and Password in Stunnel
by Jim Murphy 07 Mar '12

07 Mar '12

I have a program that only allows me to enter a From email address and a mail server IP in its setup. Is there any way that I could enter a username and a password in stunnel.conf and let Stunnel send this information out to Office 365 or Gmail for delivery? Thanks! Jim

Hello Michal, 2012/3/5 Michal Trojnara <Michal.Trojnara(a)mirt.net> > I fixed it: > ftp://ftp.stunnel.org/stunnel/**beta/stunnel-4.53b10.tar.gz<ftp://ftp.stunnel.org/stunnel/beta/stunnel-4.53b10.tar.gz> > Please give it a try and let me know whether it works for you. I tried the beta and the error is definitely gone. However I will stick with 4.45 for now as my next deployment is already prepared. Thanks a lot for your assistance!

Couple of issues with 4.45
by Philippe A. 07 Mar '12

07 Mar '12

Hello, I have encountered a couple of issues with stunnel 4.45 on RHEL 5.5. I tried configuring stunnel to log messages in /var/log/messages and later found that messages were logged both in that file AND /var/log/messages. In stunnel.conf, I had specified: debug=local6.info In syslog.conf: local6.* /var/log/stunnel.log I could achieve what I wanted only with the combination of the following two options: syslog=no output=/usr/local/app/stunnel/var/stunnel.log Is this expected? The second issue I have noticed is that stunnel seems to have a bit of trouble handling the hup signal. If you start stunnel specifying a relative path to the config, sending hup will cause stunnel to log and error but it won't exit. 2012.03.01 16:31:29 LOG5[19000:0]: Reading configuration from file etc/server.conf 2012.03.01 16:31:29 LOG3[19000:0]: etc/server.conf: No such file or directory (2) 2012.03.01 16:31:29 LOG3[19000:0]: Cannot read configuration 2012.03.01 16:31:29 LOG3[19000:0]: Failed to reload the configuration file If you specify an absolute path, no error will be reported but stunnel will exit anyway.

No sub folders, calendar or contacts
by Jonathan Harrison 05 Mar '12

05 Mar '12

Dear sirs I am using Ubuntu 11.10 64-bit, Outlook 2007 and 4 x gmail accounts (1 x personal (gmail.com) and 3 x business (baroni-limited.com, hosted by gmail). I have set up Stunnel, I belive the latest version and created a SSL license as instructed. The Stunnel Telnets OK and I can send and recieve eMails (I do send directly via my ISP rather than use Stunnel) without any problem. Where I seem to be having problems is that: I have no sub folders to each account. None are appearing. I have no calendars - I have followed the instructions but they fail to load. I have no contacts. Message from Outlook: Sync error > > Task 'Synchronizing subscribed folders for Baroni.' reported error > (0x800CCC0E) : 'Outlook cannot synchronize subscribed folders for Baroni. > Error: Cannot connect to the server. If you continue to receive this > message, contact your server administrator or Internet service provider > (ISP).' > > Task 'Internet Calendar Subscriptions' reported error (0x8004010F) : 'The > operation failed. An object cannot be found.' > Config attached - I hope. It is most likely I have missed something or done something wrong. I have not found anything to help me on the web or archives, could you please advise. If you feel you need a copy of the the logs, please advise and I shall happily provide what I can. I am assuming I have just missed something. -- Regards Jonathan

Stunnel in Client / Server configuration
by Michael Curran 04 Mar '12

04 Mar '12

Hello, I have 2 servers in different locations across the country. I am using them as a paired tunnel that both act as server and client Server A has this configuration (cert definitions left out on purpose, but exist and are valid) ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = all ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/lib/stunnel4 setuid = stunnel4 setgid = stunnel4 ; PID is created inside chroot jail pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = rle TIMEOUTclose=0 ; 128-bit or highter only ciphers = HIGH:MEDIUM ; Workaround for Eudora bug options = DONT_INSERT_EMPTY_FRAGMENTS options = NO_SSLv2 ; Some debugging stuff useful for troubleshooting debug = local7.info ;warning [Tunnel from Server B] accept = 1.2.3.4:443 connect = 127.0.0.1:8082 [Tunnel to Server B] accept = 5.6.7.8:3132 connect = 9.10.11.12:4000 client = yes Server B (cert definitions left out on purpose, but exist and are valid) ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = all ; Some security enhancements for UNIX systems - comment them out on Win32 chroot = /var/lib/stunnel4 setuid = stunnel4 setgid = stunnel4 ; PID is created inside chroot jail pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = rle TIMEOUTclose=0 ; 128-bit or highter only ciphers = HIGH:MEDIUM ; Workaround for Eudora bug options = DONT_INSERT_EMPTY_FRAGMENTS options = NO_SSLv2 ; Some debugging stuff useful for troubleshooting debug = local7.debug ;warning [Tunnel to Server A] accept = 10.1.2.3:9443 connect = 1.2.3.4:443 client = yes [Tunnel from Server A] accept = 9.10.11.12:4000 connect = 10.4.5.6:3132 Communication through Server A (client) to Server B (server) works as expected Communication through Server B (client) back to Server A (server) recieves this error curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (this is all the further it gets, the client says hello and the server responds with this) If I skip the local stunnel config and pass the traffic publicly through to Server A (running in client mode), from Server B, I get the expected http response I setup to test the tunnel. Im just assuming that if I am passing from Stunnel from one system to stunnel on another, one of them should be client and the other should be server. This works well on our old configurations and as far as I can see from a stunnel and network route perspective all rules are identical. Why would it work from Server B to Server A on the response if I go directly to Server A, but fail locally? The configuration looks correct, what else could I check?

Multiple Config Files
by Scott McKeown 02 Mar '12

02 Mar '12

Hi All, I'm new to the STunnel system but I'm loving what I have seen so far. However, I was wondering if its possible to have a setup something along the lines of the following: general.cfg - containing my general server system details http.cfg - containing the details of my HTTP server pop3.cfg - containing the details of my pop3 server etc. etc. but linking them all from one file so that if I want to remove the pop3 service I can just remove the pop3.cfg file and one line from the base file. I hope that someone understands what I'm getting at but if you need any more info please just let me know. Yours, Scott

linux default installation
by John A. Wallace 29 Feb '12

29 Feb '12

Hello. I am comparing a default installation of "stunnel.conf" in Linux with that in Windows, and I found some differences that I have a couple questions about. The Windows installation installed in client mode by default, but the one for Linux in server mode. I made a backup copy of the default files for both. For now I want to run stunnel in Linux in client mode, so I am making some changes to it. The installed default for these six parameters are as follows: Client=no Chroot=/var/lib/stunnel/ Setuid=stunnel Setgid=nogroup Pid=/var/run/stunnel.pid Cert=/etc/stunnel/stunnel.pem Is it correct to change these settings for testing in client mode so that they match the current Windows' client mode configuration, like so: Client=yes #Chroot=/var/lib/stunnel/ #Setuid=stunnel #Setgid=nogroup #Pid=/var/run/stunnel.pid #Cert=/etc/stunnel/stunnel.pem

stunnel log delayed
by John A. Wallace 29 Feb '12

29 Feb '12

Hello, I am running stunnel on Linux in client mode, and I have the following setting in "stunnel.conf": output=stunnel.log The log does not get written to periodically while the program is running but is delayed until after I have closed the program. It would be helpful to be able to look at it from time to time, especially while troubleshooting. Any way "to push" the data down into the file sooner? Thanks. John
