Logging
A log file can be updated on the authentication host to record when a Terminal Server is
powered up, rebooted, and users and ports are connected and disconnected. This
information is of particular importance to administrators who need to record users logging in
and out. In addition, when the logger is enabled the Terminal Server completes a time stamp
every 5 minutes to record that the Terminal Server is still active. This allows an administrator
to gain an accurate record of events.
See User authentication/logging on page 68 (via the Access section of the Administration
Menu).
When the Terminal Server is powered up a Telnet connection is established to the
authentication host with the Logger user name. The Terminal Server records users logging in
and out of the log file access.log. The logger only connects at Terminal Server start-up time
and the connection stays open until the unit is reset. The Terminal Server checks the log TCP
connection every 60 seconds. The logger may be restarted via the kill command by adding
two to the number of ports on your server (for example, use four for an Terminal Server2, six
for an Terminal Server4, ten for an Terminal Server8, eighteen for an Terminal Server16). If
the host authentication succeeds, but logger fails to log events, then the port connection is
dropped.
