Look at this page http://www.stunnel.org/faq/stunnel.html#configuration_file In service level options section, under the explanation of "CRLpath" it is said that all files in it should be of the form XXXXXXXX.0. But my stunnnel setup worked only when i names as XXXXXXXX.r0 instead of XXXXXXXX.0. -- Sandeep Kumar http://students.iiit.ac.in/~sandeep_kr

Thanks for reply. Yesterday, I have tried to compile stunnel with Sun Studio. It got problem linking with libwrap, so I turned off libwrap support. And it compile (without knowing there is a libwrap patch) and there is only one single running stunnel process. Regards Patrick

Hi I use this to compile stunnel: The gcc and openssl is from Solaris SFW. # export CC=/usr/sfw/bin/gcc # ./configure --with-threads=pthread --with-ssl=/usr/sfw --localstatedir=/var After installing and starting stunnel, I found there are mutiple stunnel processes. There is a PID file which store one of the stunnel process. I have tried to kill that PID, stunnel is bring down. But there other stunnel processes running. Any ideas? Regards Patrick

Config Sanity Check
by Caplan, Michael 19 Jul '08

19 Jul '08

Hi There, I am working through an issue with a script that builds a socket connection to stunnel. Stunnel is being used to relay to an Apache web server. I'm building a localhost TCP connection on port 54322, and writing my HTTP data. When reading data back from the socket connection in my script I'm sometimes getting nothing, and other times getting the proper result. I can confirm that the web server is always receiving the request and returning a proper response. Wireshark shows SSL data being transmitted and received, so stunnel is doing its thing. However, the response does not seem to be relayed to my script on the other side of stunnel *sometimes*. My hunch is that I am doing something wrong with my script, but I am hoping that an stunnel guru can rule out any oddities with my stunnel setup. My config is below as well as the output of my log file. Any thoughts? Thanks!

Difference between verify level 2 and 3
by Sandeep Kumar 16 Jul '08

16 Jul '08

Hi, I searched a lot on google, in the archives, and in the FAQ page, but could not find the differences between verify levels 2 and 3, other than the one line explanation given on the FAQ/man page. Specifically, I want to ask: 1. Is verify level 3 same as 2, but asks for client certificates as well? (Seems unlikely but still..) 2. Since verify level 2 also demands CApath/CAfile to be present, then it also is ultimately verifying against locally installed certs, which is supposed to be level 3's behaviour? Thanks & regards, Sandeep Kumar http://web.iiit.ac.in/~sandeep_kr

SSL with SMTP problem - sTunnel 4.25 Windows
by dscycler 14 Jul '08

14 Jul '08

I am using sTunnel 4.25 for Windows to send and receive e-mail from a GoldMine client. sTunnel has worked well over the years but am having an issue with a particular mail host, Live Office. They have implemented SMTP SSL on port 25. The debug log is as follows: 2008.07.14 13:45:11 LOG7[2136:5356]: smtp accepted FD=224 from 127.0.0.1:1907 2008.07.14 13:45:11 LOG7[2136:5356]: Creating a new thread 2008.07.14 13:45:11 LOG7[2136:5356]: New thread created 2008.07.14 13:45:11 LOG7[2136:4944]: smtp started 2008.07.14 13:45:11 LOG7[2136:4944]: FD 224 in non-blocking mode 2008.07.14 13:45:11 LOG5[2136:4944]: smtp accepted connection from 127.0.0.1:1907 2008.07.14 13:45:11 LOG7[2136:4944]: FD 232 in non-blocking mode 2008.07.14 13:45:11 LOG7[2136:4944]: smtp connecting 64.70.94.196:25 2008.07.14 13:45:11 LOG7[2136:4944]: connect_wait: waiting 10 seconds 2008.07.14 13:45:11 LOG7[2136:4944]: connect_wait: connected 2008.07.14 13:45:11 LOG5[2136:4944]: smtp connected remote server from 127.0.0.1:1908 2008.07.14 13:45:11 LOG7[2136:4944]: Remote FD=232 initialized 2008.07.14 13:45:11 LOG7[2136:4944]: SSL state (connect): before/connect initialization 2008.07.14 13:45:11 LOG7[2136:4944]: SSL state (connect): SSLv3 write client hello A 2008.07.14 13:45:11 LOG7[2136:4944]: SSL alert (write): fatal: handshake failure 2008.07.14 13:45:11 LOG3[2136:4944]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2008.07.14 13:45:11 LOG5[2136:4944]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2008.07.14 13:45:11 LOG7[2136:4944]: smtp finished (0 left) I am looking for help to troubleshoot the connection problem. Is this an sTunnel issue or a mail server issue? Are there conf file settings to address the issue? Thanks, DavidS

Thank you for reply. I tryied it but it doesn't work because my client run some separated subprocesses and are them that contact the server so, if an extern process try to connect to 127.0.0.1:<the_found_port> while one of that subprocess has finished and the next is not yet started, it will be able to do it and also my subprocess will be pending (i tryed it). Hope i was able to explain the situation. Any suggestion?
