# 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 once at the start of Fail2Ban.# Values: CMD#actionstart = if ! ipset -quiet -name list f2b-<name> >/dev/null;then ipset -quiet -exist create f2b-<name> hash:ip timeout <bantime>;fi# Option: actionstop# Notes.: command executed once at the end of Fail2Ban# Values: CMD#actionstop = ipset flush f2b-<name># Option: actionban# Notes.: command executed when banning an IP.
