In my kamailio configuration, I already have "#!define WITH_TLS". And some
more about my configuration:
listen=tls:XX.XX.XXX.XX:5061
#!ifdef WITH_TLS
enable_tls=yes
#!endif
#!ifdef WITH_TLS
loadmodule "tls.so"
#!endif
#!ifdef WITH_TLS
# ----- tls params -----
modparam("tls", "config",
"/usr/local/kamailio-3.3/etc/kamailio/tls.cfg")
#!endif
And my tls.cfg is,
[server:default]
method = SSLv23
verify_certificate = no
require_certificate = no
private_key = /usr/local/kamailio-3.3/etc/kamailio/kamailio.key
certificate = /usr/local/kamailio-3.3/etc/kamailio/kamailio.pem
[client:default]
verify_certificate = yes
require_certificate = yes
I have just installed kamailio 3.2.4 on some other server to see whether
the problem is with my configuration/my system or with kamailio release. I
again installed Ubuntu, and I installed the requested packages via apt-get,
as I had done on problematic system. I used exactly the same configuration
file, except changing the domain/ip values. And it worked. Then I used the
same configuration file on some other versions of Ubuntu server, and it
worked again. So, it really seems as a bug in kamailio.
It seems the worker children cannot be forked for some reason at startup,
so I enabled WITH_DEBUG directive and restarted the kamailio. The output is
attached to this mail. I hope it helps.
Best,

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.
Cheers,
Daniel

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

Process:: ID=3 PID=5916 Type=MI FIFO

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'?
Cheers,
Daniel
