Hi Carsten,
I would expect that if it didn't have children, it wouldn't report that it's listening.
However, you have asked the right question...
On my command line, I was using the -D flag to prevent daemon mode. When I configure to ONLY listen for tcp, I get:
Listening on tcp: 192.168.44.66:55060 Aliases: <snip>
WARNING: no fork mode and no udp listen address found
With that clue, I tried it without the -D flag, configured for both tcp and udp... now it is verifiably listening for tcp!
So, it turns out that with -D, the report that it is listening is inaccurate.
Thanks for your suggestion!
Dave.

"WARNING: no fork mode"
So you'll probably don't have any children for TCP...
Kind regards, Carsten

netstat is a bit tricky. Luckily it's now obsoleted by ss
Try
netstat -a -n | grep 5060
Also check if your kamialio.cfg file has "disable_tcp=yes" Comment it out if it does.
P.S. I only asked about whether it was still running because it can easily die on startup if the scripts detect some error like the control files still exists. I just checked now on my system which I installed using 'official' RPMs for Centos 6. The 'service kamailio restart' command appears to work but fails quietly for the following reason
Apr 12 14:55:40 sentinel /usr/sbin/kamailio[7501]: ERROR: ctl [ctl.c:379]: ERROR: ctl: could not delete unix socket /tmp/kamailio_ctl: Operation not permitted (1)

Hi Jeremy,
Thanks for the suggestion, I'm hoping I haven't overlooked something quite that obvious!
The last debug output I see on startup is:
Listening on udp: 192.168.44.66:55060 tcp: 192.168.44.66:55060 Aliases: <snip>

netstat shows listening for UDP on 55060, but nothing on TCP:
$ netstat -l | grep 5060 udp 0 0 192.168.44.66:55060 *:*
ps shows four kamailio processes running, all of which end when I Ctrl-C.
Cheers, Dave.

Have you checked to make sure it's still running?

Hello All,
New to Kamailio, I'm running 4.0 on Ubuntu 12.04 (precise).
Running from the command line with a minimal config, it tells me that it is listening on port 5060 for both TCP and UDP. I see the same behaviour with the default cfg.
However, netstat does not list anything listening on TCP port 5060 and an attempted connection is rejected consistent with there being no open socket.
Any suggestions on where I need to be looking to fix this?
