Hi,

I have downloaded and installed only the new rpm : kamailio-5.0.0-10.1.x86_64.rpm. Is it enough ?

Then I try to start Kamailio that fails :

[root@vm-vse02-siprouter2 kamailio]# service kamailio start

Starting kamailio (via systemctl): Job for kamailio.service failed. See 'systemctl status kamailio.service' and 'journalctl -xn' for details.

[root@vm-vse02-siprouter2 kamailio]# systemctl status kamailio.service -l

I get also a strange result when I try to start Kamailio using the service Kamailio command, that is nothing happen, the server doesn’t give a status :

[root@vm-vse02-siprouter2 ~]# service kamailio start

Starting kamailio (via systemctl): ^C

I have to send a CTRL C to break the action.

Hello,

apparently the /var/run/kamailio folder was not created by the init.d script for rpm, as it is done in the deb specs. I updated it and triggered a rebuild of rpms, available at:

https://build.opensuse.org/package/show/home:kamailio:v5.0.x-rpms/kamailio50

Try to upgrade and then see if it works.

Later today we will release v5.0.1 and the rpms for it will have the new init.d script.

Cheers,
Daniel

Hi,

I use « service kamailio start », so the init.d script that is the one created at the installation.

Hello,

how do you start Kamailio? Via init.d/systemd script?

Hi,

Well, with one of my colleagues, we did some research and test, but we don’t find where the privilege issue is with the /var/ FS.

If the fifo filename is "/var/run/kamailio/kamailio_rpc_fifo" or "/var/run/kamailio_rpc_fifo", we have this privilege issue.

I thought that the following declaration would prevent this security issue :

modparam("jsonrpcs", "fifo_name", DEFINE_FIFO_NAME)

modparam("jsonrpcs", "fifo_mode", 0755)

modparam("jsonrpcs", "fifo_group", "kamailio")

modparam("jsonrpcs", "fifo_user", "kamailio")

but it is not the case.

For the moment only the fifo filename “/tmp/kamailio_rpc_fifo" is valid for kamailio to start.

Hi,

I continue to investigate on this area.

I’m thinking that there are some security settings on the FS /var/, and I’m looking for if we have the rights to change it (I work for a project and don’t have all the ability to change some settings without agreement).

I’ll update you later tomorrow.

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,

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,

        }

}

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.
