Chapter 5 Modem authentication and logging
Introduction
Your Terminal Server provides authentication support to validate users connecting to the
serial port, and can update a host log file on connection states. Authentication and logging is
achieved by using a designated authentication host to validate users and keep connection
information. This unique facility takes the burden away from the unit and more importantly
allows the administrator to configure one host, rather than configuring multiple terminal
servers.
The Host Authentication And Logging menu may be accessed via the administrator from the
access option in the Administration Menu.
Option Description
Authentication When the Terminal Server port has authentication set to
host or both, the user is required to enter a user name
followed by a password when dialed in. The user ID and
password are forwarded to the authentication host for
validation. By setting the authentication hosts network port
to 23 or 513, this allows the user ID to be checked against
the standard Unix login system (see
Tips on page 74 ). This
feature also allows proprietary user validation code to be
written on any TCP/IP platform by choosing another
network port number.
Logging During the Terminal Server start up, a telnet session is
established to the authentication host, with the pre-defined
Log Username and Logger password. Serial events like
users logging in and out are recorded in the defined Log
File.
Note
RADIUS is often associated, but not required, for dial-in services. RADIUS offers three
major functions: authentication, logging and user services. Terminal Server can be
configured to offer all of these features but without using RADIUS. This section explains
how.
