/**

 * Plugin: UPNP router

 * Author: Sebastian S. (scitor@@el337.de)

 * Version: 0.1 (TESTING)

 *

 * Munin (http://munin.projects.linpro.no/) plugin for monitoring traffic on UPNP enabled routers.

 *

 * Requirements:

 ***************

 * - PHP (translate it for performance gain)

 * - upnpc (MiniUPnP client: http://miniupnp.tuxfamily.org/)

 *

 * Usage:

 ********

 * Copy to upnp_router_ your munin plugins directory (/usr/share/munin/plugins) and execute:

 *

 * $ munin-node-configure --shell

 *

 * Don't forget to enable UPNP on your router, the script should find any connections automatically.

 * Change the path of your upnpc binary if you didn't make install it.

 *

 ********************

 * TESTING VERSION! *

 ********************

 * Please Note: This version was only tested on one single router so far.

 * I tried to make the router detection pretty general, but you never know.

 * If you have a router with enabled upnp not beeing detected by this script

 * feel free to send me an email with your output of:

 *

 * $ upnpc -s

 *

 * command.

 *

 * Changelog:

 ************

 * version 0.1 - 26 Aug, 2009
