Logging
A log file can be updated on the authentication host to record when an IOLAN+ 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 IOLAN+ completes a time stamp every 5 minutes to
record that an IOLAN+ is still active. This allows an administrator to gain an accurate record
of events.
See User authentication/logging on page 72 (via the Access section of the Administration
Menu).
When the IOLAN+ is powered up a Telnet connection is established to the authentication
host with the Logger user name. The IOLAN+ records users logging in and out of the log file
access.log. The logger only connects at IOLAN+ start-up time and the connection stays open
until the unit is reset. The IOLAN+ 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 IOLAN+2, six for an IOLAN+4, ten for an IOLAN+8,
eighteen for an IOLAN+16). If the host authentication succeeds, but logger fails to log
events, then the port connection is dropped.
