# Fail2Ban configuration file
#
# Author: Daniel Black
#
# This is for ipset protocol 4 (ipset v4.2). If you have a later version
# of ipset try to use the iptables-ipset-proto6.conf as it does some things
# nicer.
#
# 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.
#
# If you are running on an older kernel you make need to patch in external
# modules. Debian squeeze can do this with:
# apt-get install xtables-addons-source
# module-assistant auto-install xtables-addons
#
# Debian wheezy and above uses protocol 6
