    Use ssh to run a "at now" type of job.

    I have a need to terminate a number of AIX 5.1 systems
    from a single script. I can do this using ssh. However,
    if I issue the shutdown command from ssh , it will
    wait for the command to be executed; the shutdown
    command will kill the remote sshd, and my script
    will hang until the socket times out - a long time,
    more than 5 minutes.

    Since the purpose of this is to shut down a number of systems
    quickly in event of a disaster, this is a problem.

    Is there anyway to launch the shutdown command via ssh
    and terminate and go the the next script step. Running
    the command in the background does not help.
