Munin contributed plugins

#!/bin/sh

#

# Wildcard-plugin to monitor IP addresses through iptables. To monitor an

# IP, link fwbuilder_<ipaddress> to this file. E.g.

#

#    ln -s /usr/share/node/node/plugins-auto/fwbuilder_ /etc/munin/node.d/fwbuilder_192.168.0.1

#

# ...will monitor the IP 192.168.0.1.

#

# Aditionally, you need Accountingrules in fwbuilder

#	fwbuilder creates Chains in INPUT-, OUTPUT- and FORWARD-Chain

#	with Rules that "RETURN"

#	You will have to specify rule options with name "ACCOUNTING" for the 

#	rules to use, otherwise no rules will be found.

#	try "fwbuilder_ suggest" to see if all is ok. 

#    

#

# Furthermore, this plugin needs to be run as root for iptables to work

#

# This plugin is based on the if_ plugin.
