In case that it is about a HTTP farm you should have a “pound” process running that should open a control socket defined in the directive “Control” of the farm configuration file “/usr/local/relianoid/config/FARM-NAME_proxy.cfg”. Then, you could execute the ctl command over such socket defined in the farm configuration.
root@noid-ce:~# /usr/local/relianoid/app/pound/sbin/poundctl -c /tmp/<FARM_NAME>_proxy.socket
If the socket is defined but doesn’t exist then that could be the status problem faced. Restarting the farm should regenerate the socket file.
Cheers.
