No. It does not start at all, so it does not terminate. fexsrv logs everything and when running with stunnel 5.x the log file is empty. But meanwhile I found the error: stunnel 5.x needs the a full path for the exec statement: exec = /usr/bin/perl For stunnel 4.x it was sufficent to use: exec = perl -- Ullrich Horlacher Server und Virtualisierung Rechenzentrum TIK Universitaet Stuttgart E-Mail: horlacher(a)tik.uni-stuttgart.de Allmandring 30a Tel: ++49-711-68565868 70569 Stuttgart (Germany) WWW: http://www.tik.uni-stuttgart.de/ REF:<45835cd9-b239-d80c-38a0-3f978132e40e(a)stunnel.org>

Upgrade from 5.03 to 5.35
by Hon Quach 07 Sep '16

07 Sep '16

Hi, When I perform the upgrade the stunnel service won't start, it tries to load the pem files but it is failing. I noticed when I install stunnel on my test system, the conf file is different from the version 5.03. I'm looking for documentation a on how to perform a clean upgrade but I'm having difficulty finding that information. Thanks! Sent from my iPhone
