by Jeff Salisbury 03 Apr '12

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

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

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 ?
