-# Fail2Ban configuration file
-#
-# Author: Andrew St. Jean
-#
-# Use nsupdate to perform dynamic DNS updates on a BIND zone file.
-# One may want to do this to update a local RBL with banned IP addresses.
-#
-# Options
-#
-# domain DNS domain that will appear in nsupdate add and delete
-# commands.
-#
-# ttl The time to live (TTL) in seconds of the TXT resource
-# record.
-#
-# rdata Data portion of the TXT resource record.
-#
-# nsupdatecmd Full path to the nsupdate command.
-#
-# keyfile Full path to TSIG key file used for authentication between
-# nsupdate and BIND.
-#
-# Create an nsupdate.local to set at least the <domain> and <keyfile>
-# options as they don't have default values.
-#
-# The ban and unban commands assume nsupdate will authenticate to the BIND
-# server using a TSIG key. The full path to the key file must be specified
-# in the <keyfile> parameter. Use this command to generate your TSIG key.
-#
-# dnssec-keygen -a HMAC-MD5 -b 256 -n HOST <key_name>
-#
-# Replace <key_name> with some meaningful name.
-#
-# This command will generate two files. Specify the .private file in the
-# <keyfile> option. Note that the .key file must also be present in the same
-# directory for nsupdate to use the key.
-#
-# Don't forget to add the key and appropriate allow-update or update-policy
-# option to your named.conf file.
