Which gets into the issue of defining your requirements. This message defines your requirements a bit better than "how do I send RADIUS packets" > So if I could run 10 copies of radclient in one process (each in a > different thread for example), I can write code to co-ordinate what each > thread should do for each test case. The server comes with a RADIUS API. You can use the API to create an application that sends and receives RADIUS packets. > Some of them receive RADIUS packets and send responses (acting as > servers).

No. But the "radiusd" server can. > Hope this illustrates the functionality I mentioned as desired in my > original email. > In BOTH cases, the AAA server is expected to forward RADIUS requests to > a different network element and it behooves a test application to see > both ends. What you're describing is a RADIUS simulator for a specific test environment. That doesn't exist. It is a *very* custom piece of software. FreeRADIUS can do a lot of this, but you will still need to write all of the custom rules for processing, timing, etc. > In Case 1, the AAA server proxies the Disconnect Request to a different > network element based on the location of the subscriber.
