Hello,
as recently as last week, someone encountered an file access problem
while installing Siremis, which is using also some temporary files in
/var/, even it was granting provileges via chown and chmod. All went
fine after disabling selinux. It was on a centos.
I am not saying it is the same, but it could, so try without centos to
see if the issue persists.
Cheers,
Daniel

Hi,
This is the RHEL 7.1 distro, and there is use of selinux, apparmor or
other tools.
Are you meaning that the /var/run/ folder would be secured more than
other folders?

Hello,
kamailio should attempt to create the /var/run/kamailio folder if the
application is run with enough privileges. However, some operating
systems add more constraints on top of the execution user.
What is your OS distro? Do you have selinux, apparmor or other similar
tools enabled?
Cheers,
Daniel

If I replace the values in the 2 files as appropriate :
In the ‘kamctlrc” toRPCFIFOPATH="/tmp/kamailio_rpc_fifo"
In the ‘kamailio.cfg” to!!define DEFINE_FIFO_NAME
"/tmp/kamailio_rpc_fifo"
Then kamailo starts :

root 1251 1165 0 17:37 pts/0 00:00:00 grep --color=auto kam
and I can get result from kamctl/kamcmd commands :
[root@vm-vse02-siprouter1 ~]# kamctl dispatcher dump
which: no gdb in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/)

}
}]
}
}]
},
"id": 1301
}
[root@vm-vse02-siprouter1 ~]# kamcmd dispatcher.list
{
NRSETS: 1

TARGETS: {
DEST: {
URI:

FLAGS: AP
PRIORITY: 0
}
}
}
}
}
Now, if I change the fifo patch and name to
“/var/run/kamailio/kamailio_rpc_fifo’ and apply the following
rights on /var/run/ to:
chmod 755 kamalio/
chown + kamailio:kamailio kamailio/
then kamailio starts.
Is there a reason for these results ?
Thanks in advance for your answer.
Cordialement
