What is the listen parameter for tls?

IIRC, UDP is mandatory, you should have some workers for it, even you reject the traffic on it.

The default config file has TLS support inside, just enable:

#!define WITH_TLS

and then test with it to see if you can connect. If yes, compare with your config to see what you did wrong.

I swithced again to tcp, and 'kamctl ps' now gives the following:

Process::  ID=10 PID=5923 Type=tcp receiver (generic) child=3
Process::  ID=11 PID=5924 Type=tcp main process

So it seems ok for TCP, right?

The only modification I made while switching from TLS to TCP is to change the listen=... directive (and disabling tls module parameters, of course) in kamailio.cfg file. So I do not make any change on children parameter value while switching to TCP, i.e. I have the following lines in kamailio.cfg

fork=yes
children=4

Any suggestion?

Is this all the output of kamctl ps? Because there is no udp or tcp worker process. If yes, then is something wrong with your config, be sure you set proper children parameter value.

These messages are for tls. When switched to TCP, it works fine. What can be the problem?

Hello,

does registration over UDP work fine? Are these messages for tcp or tls connections?

Can you paste the output of 'kamctl ps'?

Any ideas? It really seems as a bug, as the logs say. But do you have any workaround suggestion?

Hi,
 I installed kamailio 3.2.x a few times before and they were really fine. I decided to install a fresh one and followed the instructions on http://www.kamailio.org/wiki/install/3.3.x/git. However there is a problem: clients cannot register to kamailio. Each registration attempt produces the following error in the syslog:

What could be the problem? Any suggestion?

In case you need, the server is ubuntu server 11.10, and I installed including mysql and tls modules.
