    6 #  This script verifies that "something" is listening on the port named   #
    7 #   If this doesnt work for your OS, please submit a patch                #

    9 # Usage:  port.monitor portnum [specific IP addr]                         #

   11 # The default is to look for a 'globally bound port'                      #
   12 # If your process binds to a specific IP address. you MUST specify that   #
   13 # IP address, or this script will not detect it                           #

   15 #  Standard UNIX status: returns 0 on good, non-0 on bad.                 #
