radtest: send packets to a RADIUS server, show reply

NAME

radtest - send packets to a RADIUS server, show reply

SYNOPSIS

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]

DESCRIPTION

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.

OPTIONS

-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 authentiction 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 2^31, 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.
