Hi All, Please help!!! Query #1: *I want to perform RFC compliance testing of FreeRadius client (not server) available with "freeradius" package.* In other words, i want to perform compliance testing on "radclient" and "radeapclient" binaries available with freeradius package. On investigation, i found that the manpage of "radclient" states: radclient is a radius client program. It can send arbitrary radius packets to a radius server, then shows the reply. It can be used to test changes you made in the configuration of the radius server, or it can be used to monitor if a radius server is up. Does it mean that freeradius client is just a dummy client and there is no point in performing compliance testing on it? I tried to run the “radclient” binary. I executed the following command for this *./radclient <server-ip> auth <secret-key>* Once the above command is executed, the control waits for the attributes entry. After the attributes are written, radclient sends radius request packet and receives response from the server and then it exits. To again send any authentication or authorization request, radclient binary needs to be executed again. As per my understanding, the binary should not have exited. As radius client sends the Access-request itself once it receives a request for any service from the user. Also, if the server does not respond, radius client shall send the request to an alternate server. This means that the radius client can handle the user requests at runtime also. So it should not exit. *Please let me know if I need some extra configuration to achieve the above functionality.* Query #2: In RFC 2131, it is mentioned that there are three entities in any freeradius setup: USER, RADIUS CLIENT, RADIUS SERVER. Does freeradius package provide a separate binary/module for USER application? If not, can we consider RADIUS CLIENT as our USER as well? Thanks, Arpit
