Hello,<br>
<br>
this is likely to be the issue with the default path to ctl socket
set in the packaging.<br>
<br>
Edit your config file, look for the lines:<br>
<br>
# ----- mi_fifo params -----<br>
#modparam("mi_fifo", "fifo_name", "/var/run/kamailio/kamailio_fifo")<br>
<br>
# ----- ctl params -----<br>
#modparam("ctl", "binrpc", "unix:/var/run/kamailio/kamailio_ctl")<br>
<br>
and uncomment the two lines with modparam.<br>
<br>
Cheers,<br>
Daniel<br>

<div dir="ltr">Hey guys,<br>
<br>
I've been pulling out my hair for a few days trying to get SCTP
with Kamailio working in CentOS 7... with no luck at all.<br>
<br>
When attempting to start Kamailio via the <em>'kamctl start' </em>command
I get the following error:<br>
INFO: Starting Kamailio :<br>
<font face="Courier New,sans-serif" size="2" style="font-size: 10pt;">ERROR: PID file /var/run/kamailio.pid does not
exist -- Kamailio start failed</font><br>
<br>
When attempting to start Kamailio via the <em>'systemctl start
kamailio' </em>command, I get the following:<br>
<font face="Courier New,sans-serif" size="2" style="font-size: 10pt;">Job for kamailio.service failed. See
'systemctl status kamailio.service' and 'journalctl -xn' for
details.</font><br>
<br>
When checking the 'systemctl status kamailio -l' command, I get
the following:<br>

So I started to think there was an issue with the SCTP config or
whether SCTP was enabled in CentOS. However, everything looks
fine:<br>
<font face="Courier New,sans-serif" size="2"># cat /proc/modules<br>
sctp 217455 2 - Live 0xffffffffa03ed000<br>
</font><br>

<font face="Courier New,sans-serif" size="2"># more

</font><br>
<font face="Courier New,sans-serif" size="2"># checksctp<br>
SCTP supported</font><br>
<br>
SCTP modules installed properly:<br>
<font face="Courier New,sans-serif" size="2" style="font-size: 10pt;">Package lksctp-tools-devel-1.0.13-3.el7.x86_64
already installed and latest version<br>

and latest version<br>
Package lksctp-tools-1.0.13-3.el7.x86_64 already installed and
latest version</font><br>
<br>
Running the ' sctp_test' command between two servers, SCTP is
working fine... I can capture SCTP packets between the servers.<br>
<br>
I've left the Kamailio.cfg file as is... with the only
modification being made to enable the SCTP module to start:<br>
<font face="Courier New,sans-serif" size="2" style="font-size: 10pt;">enable_sctp = 1</font><br>
<br>
Checking 'kamailio -v' USE_SCTP is enabled:<br>
<font face="Courier New,sans-serif" size="2" style="font-size: 10pt;"># kamailio -v<br>

<br>
I've tried installing Kamailio with the precompiled rpms for
CentOS 7, and I also followed some guides on installing in via
GIT & compiling it myself... however the issue still
remains.<br>
<br>
Any help would be greatly appreciated as I've completely run out
of ideas, and there isn't much info on the web about Kamailio
& SCTP.<br>
<br>
Thanks,<br>
Rob<br>
