# Patched version of ip_ plugin to support IPv6 and ip6tables.
# Most of plugin done by munin core developers. Modified for IPv6 support
# by Lasse Karstensen <lasse.karstensen@gmail.com> February 2009.
#
# Wildcard-plugin to monitor IP addresses through ip6tables. To monitor an
# IP, link ip6_<ipaddress> to this file with : replaced with _. E.g.
#
# ln -s /usr/share/node/node/plugins-auto/ip6_ /etc/munin/plugins/ip_2001_db8_1__100
#
# ...will monitor the IP 2001:db8:1::10.
#
# Additionally, you need these ip6tables rules as the first rules (they don't do anything, just make packet counts)
#
# ip6tables -A INPUT -d 2001:db8:1::10
# ip6tables -A OUTPUT -s 2001:db8:1::10
#
# Furthermore, this plugin needs to be run as root for ip6tables to work.
#
#
# Magic markers (optional - used by munin-config and some installation
# scripts):
#%# family=auto
#%# capabilities=autoconf suggest
IP=`basename $0 | sed 's/^ip6_//g' | tr '_' ':' `
