radtest - send packets to a RADIUS server, show reply
radtest [−d raddb_directory] [−P tcp/udp] [−t pap/chap/mschap/eap-md5] [−x ] [−4 ] [−6 ] user password radius-server nas-port-number secret [ppphint] [nasname]
radtest is a frontend to radclient(1). It generates a list of attribute/value pairs based on the command line arguments, and feeds these into radclient. It’s a fast and convenient way to test a radius server.
−d raddb_directory
The directory that contains the RADIUS dictionary files. Defaults to /etc/raddb.
−P proto
Use proto transport protocol ("tcp" or "udp"). Only available if FreeRADIUS is compiled with TCP transport support.
−t pap/chap/mschap/eap-md5
Choose the authentication method to use. e.g. "-t pap", "-t chap", "-t mschap", or "-t eap-md5",. Defaults to "pap". Using EAP-MD5 requires that the "radeapclient" program is installed.
−x |
Enables debugging output for the RADIUS client. |
|||
−4 |
Use NAS-IP-Address for the NAS address (default) |
|||
−6 |
Use NAS-IPv6-Address for the NAS address (default) |
|||
user |
Username to send. |
password
Password of the user.
radius-server
Hostname or IP address of the radius server. Optionally, you may specify a port by appending :port
nas-port-number
The value of the NAS-Port attribute. Is an integer between 0 and 2ˆ31, and it really doesn’t matter what you put here. 10 will do fine.
secret |
The shared secret for this client. |
ppphint
If you put an integer > 0 here, radtest (or actually radclient) will add the attribute Framed-Protocol = PPP to the request packet.
nasname
If present, this will be resolved to an IP address and added to the request packet as the NAS-IP-Address attribute. If you don’t specify it, the local hostname of the system will be used.
