Configuration issue - unknown client

[Dan O'Reilly]

This is my first stab at Freeradius.  I have the server installed on 
Sabayon Linux, and the radtest script runs fine.  I've done basically no 
configuration to it, because I'm not sure what to configure.

I'm writing a client on another system (it's VMS if that's germane).  I 
format & send a request packet to the server system, and get (running 
radiusd -X):

rad_recv: Access-Request packet from host 192.168.0.11:1812, id=67, length=47
Ignoring request from unknown client 192.168.0.11:1812

I'm sure I don't have the server configured properly.  So, what am I missing?

Thanks!
