Hello,

I have set up kamailio 3.1.2 on an install of Debian Squeeze, using the default config but with the following defines enabled:

WITH_MYSQL
WITH_AUTH
WITH_USRLOCDB
WITH_NAT

Everything works as expected when starting Kamailio from a terminal, e.g.
service kamailio start

But after a reboot, the service fails to start and all SIP requests are dropped with a ICMP port unreachable error.

The following is an extract of /var/log/syslog when this problem occurs. It looks like Kamailio is failing to access the mysql socket, as the mysql service has not yet started?

the logs shows that the mysql server is started after kamailio. Be sure you set the order at startup to run mysql first, maybe google helps to find the proper way.

Cheers,
Daniel


Both the Kamailio and mysql services start with priority 18 on run levels 2345. I tried adjusting the Kamailio service to priority 19, but the problem still occurs.

I am relatively new to Kamailio and mysql as well as Linux / Debian administration, so I'm not really sure how to solve this problem. Any ideas would be greatly appreciated.

Regards,
Rick Aldred
