I'm trying to configure openSIPS and RTPEngine on a Debian 8.10 server but when I set WSS in opensips.cfg and restart it I get this error with any port I tried:

ERROR:core:tcp_init_listener: bind(b, 0x7fe77b0c0e5c, 16) on 192.168.0.143:555 : Permission denied
ERROR:core:trans_init_all_listeners: failed to init listener [192.168.0.143], proto wss

In /etc/default/opensips I set USER / GROUP to root and when I restarted openssips I had root privilages in an SSH terminal, but the same happens if I log into the server directly.

In the openSISP Documentation it is stated that you need super user privilages because the port 443 needs it. But I don't see how I can get higher access then root and also any other port I tried isn't privilaged so it should work, but it doesn't.

What could be the problem? How can I solve this?

  • Did you double-check your `systemd` settings? Just list the package contents and locate the file. I often find it that it overrides what I place within `/etc/default/opensips`. – Liviu Chircu Mar 03 '18 at 12:51

    Thanks. I checked and in the opensips.service file for the user/group opensips was defined so the service ignored my settings in the default file – Laci K Mar 08 '18 at 00:27

  • Great answer, I also changed my user and group to root. Run the command ``sudo systemctl daemon-reload`` before starting opensips. – Emmanuel Aliji May 13 '23 at 22:54
