Example radius client program
radtest [-d<called_id>] [-f] [-g<calling_id>] [-h] [-i<id>] [-p<port>] [-s<secret>] [-t<type>] [-v] [-x[<level>]] -u <username> <password>
radtest sends a RADIUS packet to a server running on the same host as radtest, and prints out the attributes returned.
-h
Show summary of options.
-u <username> <password>
Specifies username and password (notice that this takes two arguments).
-d <called_id>
Sets Called Station Id.
-f
Send framed dialin hint. (-t overrides this.)
-g <calling_id>
Sets Calling Station Id.
-i <id>
Use id as the packet identifier.
-p <port>
Use port as the port to connect to (defaults to definition in /etc/services, or 1645).
-s <secret>
Specifies the RADIUS shared secret (defaults to "localkey").
-t <type>
Send type as the service type (overrides -f). This is a number.
-v
Prints out the version.
-x [ <level> ]
Sets the "verbose level" to level or without an argument, increments it. (Not used.)
It doesn't support accounting packets. It always fills in the NAS-IP-Address as 127.0.0.1 and the NAS-Port as 1. Passwords longer than 16 characters are not supported. It looks for its dictionary in the same directory its run from.
