Radclient
From FreeRADIUS Wiki
radclient is a radius client program included as part of FreeRADIUS. 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.
radclient reads radius attribute/value pairs from it standard input, or from a file specified on the command line. It then encodes these attribute/value pairs using the dictionary, and sends them to the remote server.
The User-Password and CHAP-Password attributes are automatically encrypted before the packet is sent to the server.
