# Fail2Ban configuration file

# 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
