Q:

Reload Freeradius clients without restart the service

Is there a way to reload the Freeradius clients configuration without restarting the service? I'm using: 
Ubuntu Server 12
Freeradius 2.1.10
MySQL v5.5.20 (I'm storing the clients in the "nas" table)

A:

Sending a SIGHUP to the process will reload the configuration.
The Ubuntu init script seems to take care of this for you - try service freeradius reload.
