Stunnel writing strange timestamps into my logs
by Van 10 Aug '07

10 Aug '07

I was looking through /var/log/messages for another reason and I notice this (representitive log snippet below) It's 10:50 am and while automount is writing messages that jibe with the correct time (see line 5 for example. This part of my log is from about 90 min ago), stunnel seems to be 4 hours ahead, labelling things as happening at about 1pm while everything else is happening about 9am. Where is stunnel getting it's time from? And why a separate source? How can I correct this? - Van Aug 10 13:13:01 <myserver> stunnel: LOG5[29760:3086109600]: pop3s connected remote server from 127.0.0.1:54923 Aug 10 13:13:03 <myserver> stunnel: LOG5[29760:3086109600]: Connection closed: 211 bytes sent to SSL, 56 bytes sent to socket Aug 10 13:13:34 <myserver> stunnel: LOG5[29760:3086109600]: imaps accepted connection from XX.XX.61.109:1409 Aug 10 13:13:34 <myserver> stunnel: LOG5[29760:3086109600]: imaps connected remote server from 127.0.0.1:54927 Aug 10 09:14:13 <myserver> automount[30173]: >> mount: mount to NFS server 'mgm' failed: System Error: Connection timed out.

Tunneling though an Http proxy
by Honka 10 Aug '07

10 Aug '07

Hi there, i'm trying to set up stunnel on my laptop which I use at work, and i'm trying to tunnel to my home pc for remote desktop. The only open ports on the work network are 8080, 80 and 443. So I have setup the tunnel to port 8080 onto my home pc and had it working across the network at home. (via internal and external ip's) however it isn't working here. I am assuming because we have an http proxy which requires authentication. So i'm wondering, how can I make stunnel use and authenticate with this proxy so that it will work? Cheers Honka

Stunnel message about SSL_shutdown/SSL_get_error
by Lachance, Mario 03 Aug '07

03 Aug '07

Hi, I have been using openssl_0.9.7g and stunnel_4.10 on Solaris 9 without problem for 2 years in a production environment. I want to upgrade to openssl_0.9.8e and stunnel_4.20 on solaris 10. I have done some test on a development system and I have seen a new message in stunnel log file. Old message with openssl_0.9.7g and stunnel_4.10 on Solaris 9 was : Aug 3 14:51:58 solario stunnel[345]: [ID 702911 local6.notice] Too many retries on SSL shutdown New message with openssl_0.9.8e and stunnel_4.20 on solaris 10 is : Aug 3 14:42:30 daprxuu stunnel: [ID 821868 local6.error] LOG3[20957:4]: SSL_shutdown/SSL_get_error returned 6 I don't know if this new message has replaced the old one I was getting. Can someone tell me what is behind this message "_shutdown/SSL_get_error returned 6"? Please note that I am able to transfer message with both system (stunnel 4.10 and stunnel 4.20) from a windows client without any apparent problem.

stunnel hanging during negotation with an smtp server
by Jason J. Corso 31 Jul '07

31 Jul '07

Please help: I'm trying to use stunnel to connect to a secure SMTP server -- I'm using MS Entourage 2004 on an Intel 10.4 Mac. Entourage cannot connect directly to the SMTP server over SSL because it no longer supports NTLM version 1 authentication, which the SMTP server uses. I believe stunnel can be used to workaround this problem (if I'm wrong, please say so), i.e., Entourage can connect locally to stunnel which will then connect to the remote server over SSL properly. I built and installed stunnel version 4.04-12 via Fink (compiled from source via Fink) and OpenSSL 0.9.7i-4 also via Fink. I have the following configuration file: ------ # Comment it out on Win32 cert = /sw/etc/stunnel/stunnel.pem chroot = /sw/var/run/stunnel/ # PID is created inside chroot jail pid = /stunnel.pid setuid = nobody setgid = nogroup # Some debugging stuff debug = 7 output = /dev/stdout foreground = yes [ssmtp] accept = 127.0.0.1:25 connect = xxxxxx:465 protocol = smtp ------- However, when I try to send a mail, it appears to hang while negotiating with the remote server. Here is the output: 2007.07.31 15:41:19 LOG5[5511:2684407808]: stunnel 4.04 on i386-apple-darwin8.10.1 PTHREAD+LIBWRAP with OpenSSL 0.9.7i 14 Oct 2005 2007.07.31 15:41:19 LOG7[5511:2684407808]: Snagged 64 random bytes from xxx/.rnd 2007.07.31 15:41:19 LOG7[5511:2684407808]: Wrote 1024 new random bytes to xxx/.rnd 2007.07.31 15:41:19 LOG7[5511:2684407808]: RAND_status claims sufficient entropy for the PRNG 2007.07.31 15:41:19 LOG6[5511:2684407808]: PRNG seeded successfully 2007.07.31 15:41:19 LOG7[5511:2684407808]: Certificate: /sw/etc/stunnel/stunnel.pem 2007.07.31 15:41:19 LOG7[5511:2684407808]: Key file: /sw/etc/stunnel/stunnel.pem 2007.07.31 15:41:19 LOG5[5511:2684407808]: FD_SETSIZE=1024, file ulimit=256 -> 125 clients allowed 2007.07.31 15:41:19 LOG7[5511:2684407808]: FD 6 in non-blocking mode 2007.07.31 15:41:19 LOG7[5511:2684407808]: SO_REUSEADDR option set on accept socket 2007.07.31 15:41:19 LOG7[5511:2684407808]: ssmtp bound to 127.0.0.1:25 2007.07.31 15:41:19 LOG7[5511:2684407808]: FD 7 in non-blocking mode 2007.07.31 15:41:19 LOG7[5511:2684407808]: FD 8 in non-blocking mode 2007.07.31 15:41:19 LOG7[5511:2684407808]: Created pid file /stunnel.pid 2007.07.31 15:41:25 LOG7[5511:2684407808]: ssmtp accepted FD=9 from 127.0.0.1:50091 2007.07.31 15:41:25 LOG7[5511:2684407808]: FD 9 in non-blocking mode 2007.07.31 15:41:25 LOG7[5511:25183744]: ssmtp started 2007.07.31 15:41:25 LOG5[5511:25183744]: ssmtp connected from 127.0.0.1:50091 2007.07.31 15:41:25 LOG7[5511:25183744]: FD 10 in non-blocking mode 2007.07.31 15:41:25 LOG7[5511:25183744]: ssmtp connecting xxx.xxx.xxx.xxx:465 2007.07.31 15:41:25 LOG7[5511:25183744]: remote connect #1: EINPROGRESS: retrying 2007.07.31 15:41:25 LOG7[5511:25183744]: waitforsocket: FD=10, DIR=write 2007.07.31 15:41:25 LOG7[5511:25183744]: waitforsocket: ok 2007.07.31 15:41:25 LOG7[5511:25183744]: Remote FD=10 initialized 2007.07.31 15:41:25 LOG7[5511:25183744]: Negotiations for smtp(server side) started 2007.07.31 15:41:25 LOG7[5511:25183744]: RFC 2487 detected 2007.07.31 15:41:25 LOG7[5511:25183744]: waitforsocket: FD=10, DIR=read ********* HANGS HERE *********** ...and I have to kill it.

Stunnel on Freebsd not running
by The Volo 30 Jul '07

30 Jul '07

i recently installed the latest stable version 4.20 on a shell running freebsd, i dont have root i had to install it on my account. Compile was successfull, i renamed the default stunnel.conf.. and edited it, i am running stunnel as a client and added this line at the end of stunnel.conf: [eggdrop] accept = 127.0.0.1:12345 connect = irc.efnet.net:6667 when i run stunnel it doesnt do nothing besides sending me to a new bash command line.. [volo@partyline (~/)]$ /home/volo/stunnel/sbin/stunnel /home/volo/stunnel/etc/stunnel/stunnel.conf [volo@partyline (~/)]$ I type ps -x to see if stunnel is running but i dont see it on the list and no pid file exist either. Any ideas on how i can fix this ? i dont see what i am doing wrong trying to run stunnel.. Trying to run stunnel to connect to irc and my eggdrop to connect to stunnel access ip:port thanks
