      I also used to be plagued by numerous messages about hosts all
      over our network being shut down.  These messages actually come
      to you courtesy of an RPC program called "rwall" (remote "wall"),
      which "shutdown" calls to send messages to remote hosts which it
      thinks might be interested.

      One easy way to avoid getting any such messages is to disable the
      rwall daemon that runs on your workstation (rwalld).  You can do
      this by commenting out its entry in your /etc/inetd.conf file and
      then reinitializing inetd by sending it a SIGHUP signal.

      A less extreme approach might be to have your rwall daemon run as
      something other than root (the userid for running an inetd service
      is specified in inetd.conf), so that you can selectively disable
      its messages with "mesg n" (I haven't tried this approach, so I'm
      not 100% sure that it works).

      Cheers..Y
