# Fail2Ban configuration file
#
# Author: Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl>
#
# Modified: Alexander Koeppe <format_c@online.de>, Serg G. Brester <serg.brester@sebres.de>
# made config file IPv6 capable
[INCLUDES]
before = iptables-common.conf
[Definition]
# Option: actionstart
# Notes.: command executed once at the start of Fail2Ban.
# Values: CMD
#
# Changing iptables rules requires root privileges. If fail2ban is
# configured to run as root, firewall setup can be performed by
# fail2ban automatically. However, if fail2ban is configured to run as
# a normal user, the configuration must be done by some other means
# (e.g. using static firewall configuration with the
# iptables-persistent package).
#
# Explanation of the rule below:
# Check if any packets coming from an IP on the <iptname>
# list have been seen in the last 3600 seconds. If yes, update the
# timestamp for this IP and drop the packet. If not, let the packet
# through.
#
# Fail2ban inserts blacklisted hosts into the <iptname> list
# and removes them from the list after some time, according to its
# own rules. The 3600 second timeout is independent and acts as a
# safeguard in case the fail2ban process dies unexpectedly. The
# shorter of the two timeouts actually matters.
actionstart = if [ `id -u` -eq 0 ];then <iptables> -I <chain> -m recent --update --seconds 3600 --name <iptname> -j <blocktype>;fi
# Option: actionstop
# Notes.: command executed once at the end of Fail2Ban
# Values: CMD
#
actionstop = echo / > /proc/net/xt_recent/<iptname>
if [ `id -u` -eq 0 ];then <iptables> -D <chain> -m recent --update --seconds 3600 --name <iptname> -j <blocktype>;fi
# Option: actioncheck
# Notes.: command executed once before each actionban command
# Values: CMD
#
actioncheck = test -e /proc/net/xt_recent/<iptname>
# Option: actionban
# Notes.: command executed when banning an IP. Take care that the
# command is executed with Fail2Ban user rights.
# Tags: See jail.conf(5) man page
# Values: CMD
#
actionban = echo +<ip> > /proc/net/xt_recent/<iptname>
# Option: actionunban
# Notes.: command executed when unbanning an IP. Take care that the
# command is executed with Fail2Ban user rights.
# Tags: See jail.conf(5) man page
# Values: CMD
