RE: Stunnel Forks Out of Control
by Duncan Brown 24 Feb '07

24 Feb '07

Hi all, Ok, I've gone through my last log file for when this issue happens. There's "1130 finished (2 left)" (where 1030 is the port we're listening on) at 10:22am, for example. Then, the next "1130 finished" doesn't happen for about another 20 minutes (which is weird), and then says, "1131 finished (124 left)". It's at this point that a lot of "connection reset by peer"'s happen and "0 bytes sent to SSL" also happen. It looks as though there are a bunch of connections being accepted but not handled. Can anyone assist? The debug level 7 log file is available if necessary. Thanks again, guys. Cheers, Duncan

Hi all, As an update, it looks like I'm using Stunnel 4.15. I thought it said 4.20, unless I managed to compile an older version. Regardless, I think the problem is happening in both versions. It looks as though it can't catch up on processing cached requests or something. Does that help at all? Cheers, Duncan

Stunnel Forks Out of Control
by Duncan Brown 21 Feb '07

21 Feb '07

Hi all, I apologize if this issue appears in the archives but I've scoured them and can't find any similar instances (if this problem does occur in the archives then if someone could point it out to me I'd be grateful as well). So, here goes: I'm running Stunnel on Debian Linux. I run it in daemon mode and have the .conf file set to listen on a specific port and redirect to another port. Listening on the connecting end of Stunnel is another daemon I've created that listens on the same port for TCP traffic as part of a client-server application I have (a new process is forked for each connection). On the client end is a .NET application that communicates with the server via TCP with Stunnel installed. In my code, I've made sure that whenever a client-server session is finished, the server closes the socket, whether or not there was an error. Now, everything seems to work flawlessly for a period of time (this period of time is variable, from anywhere between 1 day to 1 month). Then, all of a sudden, Stunnel "explodes"; for example, while there might be one or two forks of my own daemon, there might be 128 instances of Stunnel, all of which are in a sleeping state (that is, if I run ps -aux, their "STAT" attribute is "S"), whereas before it exploded it was pretty much a 1:1 relationship. When it "explodes", I have to kill Stunnel and restart it, which is a pain in the rear-end given what I'm trying to do. Why is it doing this? How do I stop it from happening? I apologize again if this has already been brought up somewhere else, but I've been unable to find any references to any similar problems. If it's a "newbie" mistake or something I'll gladly accept it and learn from it. Please find below the information requested for a problem for the mailing list: - I'm using v4.20 - No parameters are used from the command-line when starting Stunnel; it just uses the standard .conf file which I've edited. - Output of "uname -a" : "Linux buffed 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux" - I'm using libc v6 - Output of "gcc -v" : Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.5/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --enable-__cxa_atexit --with-system-zlib --enable-nls --without-included-gettext --enable-clocale=gnu --enable-debug --enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc i486-linux Thread model: posix gcc version 3.3.5 (Debian 1:3.3.5-13) - I'm using OpenSSL v0.9.7e (25 Oct 2004) Thanks in advance for any help.

Stunnel proxy aware
by Kennet Svanberg 21 Feb '07

Hi, I'm quite happy with stunnel-4.05 but don't know how to add any of the proxy patches to make my own windows binaries. I also saw that others have wondered http://linode.mirt.net/pipermail/stunnel-users/2006-December/001404.html

Stunnel on AIX 5.3 and AIX 5.2 - Solution
by Trevor Maistry 21 Feb '07

21 Feb '07

Hi, I downloaded stunnel version 4.05, changed the configuration file to use "cc" instead of "gcc" and compiled on AIX 5300-04 and AIX 5200-03. Compilations worked fine. However, you must compile on the machine you want to use it on. Otherwise you will have problems. Copy the "stunnel", "stunnel.pem" and sample "stunnel.conf-sample.in" files into /usr/local/bin. Rename the "stunnel.conf-sample.in" to " "stunnel.conf". Change the "stunnel.conf" accordingly and start "stunnel" like so "./stunnel stunnel.conf". Hope this helps.

slow transfer of smtp
by jason kawaja 15 Feb '07

greetings. clients connects normally when not using ssl (stunnel). when using ssl the connection on the client end appears to take about a minute but does eventually work (mail is sent through encrypted). shown below is the log with debug=7 and a space between the area where a "pause" seems to be, ideas on what could be occurring during this time to induce the "pause"? client = machine
