Re: FreeRadius logging lots of duplicates?

Mon, 07 Mar 2005 08:11:34 -0800

I've done a tcpdump while it's logging all the duplcates and all I see is one way communication. The NAS box will send 10 sessions or so to the accounting port to log but the radius never sends anything back. Why would that be?

All the traffic is one way. Would something be preventing the radius from sending the received? Something in the configuration?

I do believe that the NAS needs the return packet. 


When the NAS sends a packet to the server, the server should respond with an
accounting ack packet back to the NAS. Check that the server indeed sends an
ack packet and that the NAS receives the ack packet.

Also, on the NAS you should be able to configure how many times the NAS has
to retry to send the packet and at which interval.
The settings you should choose depend greatly on the connection between your
NAS and your server.
