    Dear Fellow Managers,

    I have a problem that perhaps you might have already solved and was
    wondering if you would be willing to advise me as to how I should
    proceed. Let me describe the scenario.

    We have two GS160s configured as a cluster with a terminal server
    connected to the console of each of the GS160 systems.

    The situation is as follows. We have technicians and consultants who
    occasionally need to dial into the consoles to carry out troubleshooting
    and repairs for us. However our site rules do not permit me to admit
    them without being able to log all of their activities in some kind of
    tamperproof way. In particular, I need to record the exact commands
    that they enter and, if possible, also record the exact responses they
    get from the machines. I need to make this happen even if they should
    shut down the node, or bring it down to single-user mode or disable
    auditing and syslogd.

    To do this, it seems that I would need to record their keystrokes and
    the characters the computers return in reply to their commands. Now the
    solution I was originally thinking of was to put the modem on a
    minimally configured Alpha and use that to field the dial-in session and
    then redirect it to the console ports of the GS160s while copying the
    keystrokes and storing it on the Alpha system. However, I am not sure
    how to "tap the line" and actually copy the typed characters as well as
    the response characters to a file while allowing those same characters
    to go on to the console ports of the GS160s. So if it can be done, how
    can I do it?

    Now my plan might not even be sound so feel free to suggest a better way
    to log the commands.

    Yours sincerely,
    Robert Honore.
