Hi All, I'm really struggling to make stunnel working for more than a few hours. (and the client is yelling hard...) (I solved some other issue : logging per website and making more than one stunnel works) To put it in a nutshell : - stunnel is running and working correctly (I can reach the website in https correctly) - after some hours I get the following situation : - stunnel is still running on linux - trying to connect to a website result in the connection taking very long time and then fails : "*The connection to * extranet.serviceplus-hse.com <http://extranet.website.com>* was interrupted. Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.*" (Chrome) Same symptoms on IE9, Firefox & Lynx (on the server that runs stunnel) (see logs below) - The following logs are the last one seen in the log file : - 2012.04.03 23:33:28 LOG5[24792:140152610346752]: Service extranet.serviceplus-hse.com connected remote server from 127.0.0.1:36256 - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Remote FD=1 initialized - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Option TCP_NODELAY set on remote socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Socket closed on read - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Sending SSL write shutdown - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: SSL alert (write): warning: close notify - 2012.04.03 23:33:41 LOG6[24792:140152610346752]: SSL_shutdown successfully sent close_notify - 2012.04.03 23:33:41 LOG3[24792:140152610346752]: transfer: s_poll_wait: TIMEOUTclose exceeded: closing - 2012.04.03 23:33:41 LOG5[24792:140152610346752]: Connection closed: 186584 bytes sent to SSL, 3275 bytes sent to socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Service extranet.serviceplus-hse.com finished (0 left) - 2012.04.04 06:25:04 LOG7[24792:140152610629408]: *Dispatching signals from the signal pipe * stopping the firewall & fail2ban do not change anything.

Ubuntu version of stunnel : multiple process shown by a ps -edf, compiled from sources : one process

Hi, To get around a bug of stunnel present in the package of Ubuntu 11.10 (that has been corrected in v4.38), I've compiled from sources (v4.53).

Transparent STunnel & HAProxy on Centos6.2
by Scott McKeown 07 Apr '12

07 Apr '12

Hi All, I've been playing with this for a little while now and before the all in front of me and my head meet I was wondering if someone else could shed some light on this for me please. First off let me give you a over view of the network setup: My Virtual Machine has two interfaces eth0 has two addresses 192.168.82.9/18and 192.168.82.10/18. 192.168.82.9 is going to be for the management of the server and 192.168.82.10 is what the website will respond too. eth1 has a network of its own 10.0.0.0/24 and I have two Debian Apache web servers that are connected to this network 10.0.0.10 and 10.0.0.20. If this was a real world setup I might have put the management address (192.168.82.9) on a different port but I didn't think of that at the time of setting this up but I may do that later. Second what have I done! Well this is a brand new install of Centos6.2 minimal fully patched and both HAProxy and STunnel downloaded and installed. I'm using the devel version of HAProxy but thats a different story and version 4.53 of STunnel. Now the problem. Both seem to work perfectly as-long as I don't want to know who is accessing my site which make it next to useless. However, I can get HAProxy to report the IP Address of the visitor as long as you visit the HTTP page on port 80 as per my configuration file. I can also get STunnel to work with HAProxy but as soon as I enable 'protocol = proxy' the HTTPS side breaks and all I get in my browser is '400 Bad Request Your browser sent an invalid request'. I've played with everything I can thing of and I still cant get a Transparent STunnel>HAProxy solution working correctly.

MySQL through stunnel - fails after many days
by Whit Blauvelt 04 Apr '12

04 Apr '12

Hi, I have a Nagios plugin using an stunnel connection to a MySQL server across the LAN for frequent queries, where each one opens a fresh connection. Checking ulimit on both ends shows "unlimited" (I've found old discussions about that being a possible factor). There's nothing I've found in the logs to show where it's going wrong. It's just that after days of running fine, suddenly the queries start failing to connect through. Restarting stunnel on both ends immediately resolves the problem. I suppose I can just restart stunnel on both ends once a day from cron and be okay. But I'd rather find a real fix, if anyone recognizes what this would be and can point me to one. Thanks, Whit

by Jeff Salisbury 03 Apr '12

Greetings, we recently updated Stunnel to version 4.53 and we've discovered that Stunnel no longer runs on our Windows 2000 workstation. Here is the message in the Stunnel log: No limit detected for the number of clients stunnel 4.53 on x86-pc-mingw32-gnu platform Compiled/running with OpenSSL 0.9.8s-fips 4 Jan 2012 Threading:WIN32 SSL:+ENGINE+OCSP+FIPS Auth:none Sockets:SELECT+IPv4 Reading configuration from file C:\bin\Stunnel\stunnel.conf FIPS_mode_set: 2D06C071: error:2D06C071:FIPS routines:FIPS_mode_set:unsupported platform Server is down Please help! Is there a configuration change or addition we can make in our Stunnel.conf file that will allow us to run v4.53 on our Windows 2000 machine? Regards, Jeff

set proxy for stunnel client
by Ebrahim Khalilzadeh 02 Apr '12

02 Apr '12

Dear Users, Hi In our network users connect to internet using http proxy. I have a configuration file like this: [proxy] accept:4444 connect:remote_ip:remote_port connecting to remote ip needs http proxy. I tested some configurations like this: [proxy] protocol = connect protocolHost = proxy_ip:proxy_port accept:4444 connect:remote_ip:remote_port or [proxy] protocol = proxy protocolHost = proxy_ip:proxy_port accept:4444 connect:remote_ip:remote_port But now no success!!! How can i set stunnel to use proxy? Regards, Ebrahim khalilzadeh --

Stunnel running for a few minutes and then stop and can't handle multiple domains
by Thomas Manson 01 Apr '12

01 Apr '12

Hi, I've setup a stunnel install to handle several website SSL part of the HTTP (then redirected to HAProxy LoadBalancer). I can successfully start one site, but if I add another website (so another stunnel conf file in /etc/stunnel) then the first is said to be already running while it's not and the second starts for real. thomas@ns0:/var/log/stunnel4$ sudo service stunnel4 start Starting SSL tunnels: [Started: /etc/stunnel/base.conf] [Started: /etc/stunnel/extranet.onesite.com.conf] *[Already running: /etc/stunnel/mansonthomas.com.conf] stunnel.* (mansonthomas.com was my first try before implementing a client website) Also, in /var/log/stunnel.log I've only the logs for base.conf, not for the two other one. What should I do to have the logs? I've tryed to add debug=7 at the beginning of the two conf file, but nothing. After some times, the extranet site https stops working... I was off in holidays for the last two weeks, so I didn't have the time to really dig into this... what would be the first steps to debug this issues ?
