<Stunnel> multiple connection
by aliquippa1 23 May '06

23 May '06

Hello I have problem with stunnel. I want to use feature which I'm not sure if is available. I want to accept connection from a host and then connect to a few hosts. I want to have something like this: accept = xxx.xxx.xxx.xxx:xxxx connect = yyy.yyy.yyy.yyy:yyyy connect = zzz.zzz.zzz.zzz:zzzz connect = vvv.vvv.vvv.vvv:vvv Now I want to get such situation: 1.accept connection from xxx. 2.try to connect to yyy. 3 if it doesn't work try to connect to zzz. 4 if it doesn't work try to connect to vvv. I wonder if it's possible, because if I use stunnel and connect from xxx it connects me only to the first host and when I connect from xxx again it connects me to the second host and after the third trial from xxx it connects me to vvv. Thanx Agnes

stunnel-4.15 segfaulting and looping under FreeBSD-CURRENT
by Michael Weiser 17 May '06

17 May '06

Hi, I've run into the problem mentioned in: > Scott Tuc Ellentuch at T-B-O-H ml at t-b-o-h.net > Fri Apr 21 23:45:11 CEST 2006 > Hi, > I just did a portupgrade in FreeBSD from 4.14 to 4.15, and now it > seems to be looping the command that I asked it, instead of just doing > it once. Has there been an option added I need to tell it to just do > once? > Thanks, Tuc I'm running stunnel in client mode. It execs uucico which receives and sends uucp jobs via stdin/stdout. The first call to uucico actually succeeds. It seems like stunnel is segfaulting and then re-exec-ing when it would normally quit. A core file is created in the current directory. But stunnel never quits and indefinitely continues to re-exec itself. Has there been any progress in solving this problem? -- Thanks, Michael

If you go to the directory " /stunnel2/sbin " without quotes, do you see 2 files named stunnel and stunnel3? If you see these files, you can execute the stunnel file with something like ./stunnel --help To display the options available to you for the daemon to run.

Thanks a lot! Craig. I use your method: ./configure --prefix=/stunnel2 It seems that installation is successful. It successfully generate a directory ./stunnel2, in which there are six subdirectories: etc lib man sbin share var But when I run stunnel command in the teminal window. It does not take it as a command. Is it supposed to run stunnel command after the installation or not? Is there anything missing in the Mac machine before it can run stunnel?

Hi, I want to install Stunnel 4.15 into MAC OS X machine. Somehow I do not have the right to make any directory in /usr so I can not install Stunnel in /usr/local. How do I install Stunnel into different directory? Thanks Peng

SSL2Proxy
by Steve Cohen 12 May '06

12 May '06

Hello all, I'm tyring to get around content based(notHostBased) int*rn*t cen$0ring. (don't want this page to be indexed with that keyword, so please don't wite it in your response). This is what I need to do: Set Browser on client machine to use <proxyX:port>, but I want content to be encrypted. The proxy is trusted(ownedByMe), everything else in between is not, after the proxy everything is trusted. So this would be the setup: SetupA: ClientBroswer <> STunnelOnRemoteServer <> LocalProxyServerOnSameServer(Squid) <> RestOfTheInternet And NOT this: SetupB: Browser<>LocalSTunnel<>RemoteSTunnel<>Proxy<>RestOfTheInternet Because I don't want any special kind of configuration on the client's local machine except for setting the proxy.(I am currently doing this via ssh tunneling) -I have squid running on remote server listening on 3128 and it works -I have stunnel running on remote server listening on 8686 and forwarding to localhost:3128, -I have Firefox set to use <myServer:8686> as proxy But when trying to use it, Firefox says connection reset.... Please tell me why this is happening and what I need to do. Feel free to make any suggestions you want, I won't be annoyed if you tell me something I already know. Thanks.

Hi all, Hi all stunnel users. I want to debug and fix some TLS bugs with stunnel. I loaded stunnel 4.14 sources but i failed to compile it with visual studio 6, under windows 2000 environment. 1. Does anybody has the dsp file to be used under VC6++ for proper stunnel compilation ??? 2. Do I need any other libraries beside openssl to link ? I will appreciate any help Regards Erez __________________________________________________________________________________________ This electronic message contains information from Verint Systems, which may be privileged and confidential.
