The client fexsrv does not start at all with stunnel 5.x, whereas with stunnel 4.27 everything works fine. > It is impossible to say anything without analysis of the executed fexsrv > program. The problem cannot be in fexsrv, because it works with stunnel 4.27 -- 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:<f0622f17-fd11-bdb8-4a82-9665463c0d64(a)olszowka.net>

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
