[SR-Users] Perl Code Execution via kamailio.cfg fails

["Nicolas Rüger"]

Hello,

finally found kind of a solution for both of my problems:

1.) 
Printing ERRORs to stderr didn't work as I started Kamailio with "./kamctl start" instead of "./kamailio"...stupid mistake...

BUT 

still don't know why Kamailio isn't writing to "syslogs" when "log_stderror=no" is set in "kamailio.cfg" (using "debian lenny")

and

still don't know why just "xlog()" works, but "log()" doesn't seem to have an effect.

2.)
My Perlscript got executed finally. I used the following command in "kamailio.cfg" in the end.

   perl_exec_simple("myprint");

My script/subroutine "myprint" actually is writing a control string in another file...just for testing...

I finally used an absolute path instead of an relative path in the perlscript for the filehandle. That worked out then. 

BUT

still don't know where Kamailio is trying to open the filehandle when I use a relative path as it's not working then. 

Note: 
When I execute the subroutine from another perlscript it works out perfectly using a relative path for the filehandle.


However....thank you for your help and hints so far!!


Regards,
Nicolas
