* CHECK_IPXPING.C
*
* Program: IPX ping plugin for Nagios
* License: GPL
* Copyright (c) 1999 Ethan Galstad (nagios@nagios.org)
*
* Last Modified: 09-24-1999
*
* Command line: CHECK_IPXPING <dest_network> <dest_address> <wrtt> <crtt>
*
* Description:
*
* This plugin will use the /usr/bin/ipxping command to ping the specified host using the
* IPX protocol. Note: Linux users must have IPX support compiled into the kernerl and
* must have IPX configured correctly in order for this plugin to work.
* If the round trip time value is above the <wrtt> level, a STATE_WARNING is
* returned. If it exceeds the <crtt> level, a STATE_CRITICAL is returned.
*
*
*
* IMPORTANT!!
*
* This plugin will only work with the ipxping command that has been ported to Linux.
* The version for Sun takes different command line arguments and differs in its output.
*
