# Fail2Ban configuration file

#

# Author: Eduardo Diaz

#

# This is for ipset protocol 6 (and hopefully later) (ipset v6.14).

# for shorewall

#

# Use this setting in jail.conf to modify use this action instead of a

# default one

#

# banaction   = shorewall-ipset-proto6

#

# This requires the program ipset which is normally in package called ipset.

#

# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0

# kernels, and you need Shorewall >= 4.5.5 to use this action.

#

# The default Shorewall configuration is with "BLACKLISTNEWONLY=Yes" (see

# file /etc/shorewall/shorewall.conf). This means that when Fail2ban adds a

# new shorewall rule to ban an IP address, that rule will affect only new

# connections. So if the attacker goes on trying using the same connection

# he could even log in. In order to get the same behavior of the iptable

# action (so that the ban is immediate) the /etc/shorewall/shorewall.conf

# file should me modified with "BLACKLISTNEWONLY=No".

#

#

# Enable shorewall to use a blacklist using iptables creating a file

# /etc/shorewall/blrules and adding "DROP net:+f2b-ssh all" and

# similar lines for every jail.  To enable restoring you ipset you

# must set SAVE_IPSETS=Yes in shorewall.conf .  You can read more

# about ipsets handling in Shorewall at http://shorewall.net/ipsets.html

#

# To force creation of the ipset in the case that somebody deletes the

# ipset create a file /etc/shorewall/initdone and add one line for

# every ipset (this files are in Perl) and add 1 at the end of the file.

# The example:

# system("/usr/sbin/ipset -quiet -exist create f2b-ssh hash:ip timeout 600 ");

# 1;

#

# To destroy the ipset in shorewall you must add to the file /etc/shorewall/stopped

# # One line of every ipset

# system("/usr/sbin/ipset -quiet destroy f2b-ssh ");

# 1; # This must go to the end of the file if not shorewall compilation fails

#

[Definition]

# Option:  actionstart

# Notes.:  command executed on demand at the first ban (or at the start of Fail2Ban if actionstart_on_demand is set to false).

# Values:  CMD

# Option:  actionstop

# Notes.:  command executed at the stop of jail (or at the end of Fail2Ban)

# Values:  CMD

#

actionstop = ipset flush f2b-<name>

# Option:  actionban

# Notes.:  command executed when banning an IP. Take care that the

#          command is executed with Fail2Ban user rights.

# Values:  CMD

# Option:  actionunban

# Notes.:  command executed when unbanning an IP. Take care that the

#          command is executed with Fail2Ban user rights.

# Values:  CMD
