≤GB≥Remote Authentication Dial-in User Service (RADIUS)≤P≥
The protocol used by remote access servers to authenticate dial-in users, as defined in ≤U2≥RFC 2138≤P0≥. This probe tests a Radius server by sending an Access-Request packet to authenticate a specific user name and password. Before you can use this probe with a particular Radius server, you must add the InterMapper computer's IP address to the Radius server and choose a "shared secret" for it. The "shared secret" is used by the Radius protocol to encrypt passwords in Radius requests. A Radius server will not answer access-requests from a client it doesn't recognize.
The officially assigned port number for RADIUS is 1812. However, some RADIUS servers use port number 1645 for historical reasons.
≤i≥Shared Secret≤p≥ is InterMapper's unique password into the RADIUS server. The same value needs to be configured into the Radius server as well, as it is used for authentication.
≤i≥User Name≤p≥ is the user you are trying to authenticate.
≤i≥Password≤p≥ is the user's password. This password is encrypted using the shared secret; it is not sent in the clear.
