💖 NAME 💖

radtest — send packets to a RADIUS server, show reply

✨ SYNOPSIS ✨

[-x ] [-4 ] [-6 ] user password radius-server nas-port-number secret
[ppphint] [nasname]

bestie, that is the whole shape of the command — copy it exactly if you are following along. 🫶

🦋 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. no cap, that is the whole vibe: quick little test, real RADIUS replies. 💖

🎀 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 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 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.
