(RADIATOR) recommended method to "event notify" radiator to a restart/reread

[Tariq Rashid]

i wonder if any commands can be passed to radiator via a
command/control/management port. similar to the way you can ask some servers
for a status over a port (i think you can ask radiator for a status over a
port connection, or was the freeradius?).

if this is possible then that would be useful as it would indicate whether
the server has sucessfuly restarted - whereas a ssh "kill -HUP" doesn't
indicate the success of the operation.
