Hi Henning,
Usually I connect on a command line like this ;
su- mysql
mysql
use siprouter;
…
If now I use
mysql -u siprouter -p
Enter password:
mysql:siprouter:(none)> use siprouter;
Database changed
So I can connect the local server.
Cordialement.

Hello Patrick,
the mysql module will usually just give you the error message back from the
server/mysql client library.
Can you try to connect with the "mysql" client command on the command line to
connect to the local server, with the same username/password as in your
Kamailio configuration?
