[OpenSIPS-Users] calling external command with sudo

[Dragomir Haralambiev]

Hello everyone,

I am trying to execute 'iptables' from opensips in the script, which works
if opensips runs as root. However if opensips is configured to run as
non-privileged user, in order to control iptables, I have to call iptables
via sudo. Command works on the command prompt when executed manually under
the user opensips run as, but does not seem to execute if run by opensips
itself.

This is how I try to call it:

exec_msg("/usr/bin/sudo /sbin/iptables -A INPUT -s $si -p udp -j DROP");

log file says command is executed, but the firewall rules do not get
updated.

Any idea why?
