OpenSER starting problem

Hi, I want ask you for help. I am new in work with OpenSER and I have this problem.
When I try start my SER "/sbin/openserctl start" i have this erorr "ERROR: PID file /var/run/openser.pid does not exist -- OpenSer start faild".
Thank you vary much for help.

This is my openser.cfg:

does the user you are trying to run openser under have sufficient access to var/run to create the file? do those directories exist? ahve you tried starting openser just using the binary and not the ctl script?

I would guess that you have an error in your openser.cfg file. I have the same problem now and when I return to a previous working version of the openser configuration file it starts fine.

It would be nice to have a tool to check for errors in the openser.cfg. Anyone who knows if this exists and where to find it? Or other tips on this matter?

Oh, and by the way, I did not take a look at your cfg file. I just wanted to share my personal experience on this.

Ok, stupid of me. In the /var/log/messages file the errors are logged of course, with line number etc.

openser: CRITICAL:core:yyerror: parse error in config file, line 386, column 1-10: syntax error

openser -c -f <your openser.cfg>

this runs your config through the parser to check syntax and a few other things.

Thanks! This works a bit easier.
