Modem Authentication & Logging 5
The 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.
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 section 5.4
Tips for Windows
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. The Terminal
Server can be configured to offer all of these features but
without using RADIUS. This section explains how.
