The parameter "-w" forces iptables to wait for a lock before printing data. The parameter requires iptables 1.6 (released 2015). See https://github.com/munin-monitoring/munin/issues/586

# iptables Accounting Tool
|
|
#
|
|
# What it does:
|
|
# It accounts data based on the counters of iptables
|
|
#
|
|
# How it works:
|
|
# You have to create a rule like this:
|
|
# iptables -I INPUT -m comment --comment "ACC-Name" ...
|
|
# iptables -I OUTPUT -m comment --comment "ACC-Name" ...
|
|
#
|
|
# You can create custom rules which matches any package which should
|
|
# be accounted. But the comment *must* begin with "ACC-" and a rule
|
|
# should be created for input and output for measuring the direction.
|
|
#
|
|
# Please specify no target on this rule, so it just counts the data.
|
|
#
|
|
# Some Examples:
|
|
# iptables -I INPUT -p udp -d 12.34.56.78 --dport 8767 -m comment --comment "ACC-teamspeak"
|
|
# iptables -I OUTPUT -p udp -s 12.34.56.78 --sport 8767 -m comment --comment "ACC-teamspeak"
|
|
# iptables -I INPUT -p tcp -d 12.34.56.78 --dport 25 -m comment --comment "ACC-mailserver"
|
|
# iptables -I OUTPUT -p tcp -s 12.34.56.78 --sport 25 -m comment --comment "ACC-mailserver"
|
|
#
|
|
# This plugin needs to be run as root for iptables to work!
