Modem Authentication & Logging
Modem Authentication & Logging 5
IOLAN+ 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 IOLAN+ 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 ® systems). 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 IOLAN+ 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. IOLAN+ can be
configured to offer all of these features but without using
RADIUS. This section explains how.
The Host Authentication And Logging menu may be accessed
via the administrator from the access option in the
Administration Menu.
