  12  *
  13  * Description:
  14  *
  15  * This plugin will use the /usr/bin/ipxping command to ping the specified host using the
  16  * IPX protocol.  Note: Linux users must have IPX support compiled into the kernerl and
  17  * must have IPX configured correctly in order for this plugin to work.
  18  * If the round trip time value is above the <wrtt> level, a STATE_WARNING is
  19  * returned.  If it exceeds the <crtt> level, a STATE_CRITICAL is returned.
  20  *
  21  *
  22  *
  23  * IMPORTANT!!
  24  *
  25  * This plugin will only work with the ipxping command that has been ported to Linux.
  26  * The version for Sun takes different command line arguments and differs in its output.
