+# 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
