Dawgs,

I received the following error when starting debug mode or issuing "freeradius reload" and catching the error in radius.log:

Tue Mar 24 16:16:05 2009 : Error: Failed binding to socket: Address already in use
Tue Mar 24 16:16:05 2009 : Error: /etc/raddb/radiusd.conf[240]: Error binding to port for 0.0.0.0 port 1812

I disabled IPv6 and verified if there is another service running on this port...

udp        0      0 0.0.0.0:631             0.0.0.0:*                           2663/cupsd

According to the outputs above there is just one service running on this port...

I don't know what else I can do. I saw all topics related to my problem but no one gave me a solution.
