# Fail2Ban configuration file
#
# Author: Edgar Hoch, Cyril Jaquier
# Author: Edgar Hoch
# Copied from iptables-new.conf and modified for use with firewalld by Edgar Hoch.
# It uses "firewall-cmd" instead of "iptables".
# firewall-cmd is based on the command of version firewalld-0.3.4-1.fc19 .
# iptables-new.conf copied from iptables.conf and modified by Yaroslav Halchenko
# to fullfill the needs of bugreporter dbts#350746.
#
# $Revision$
#
# firewall-cmd is based on the command of version firewalld-0.3.4-1.fc19.

# The following is a workaround using a loop to implement the --flush-chain command.
