# This is for ipset protocol 6 (and hopefully later) (ipset v6.14).

# Use this setting in jail.conf to modify use this action instead of a
|
|
|
9 |
# default one
|
|
|
10 |
#
|
|
|
11 |
# banaction = shorewall-ipset-proto6
|
|
|
12 |
#
|
|
|
13 |
# This requires the program ipset which is normally in package called ipset.
|
|
|
14 |
#
|
|
|
15 |
# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0
|
|
|
16 |
# kernels, and you need Shorewall >= 4.5.5 to use this action.
|
|
|
17 |
#
|
|
|
18 |
# The default Shorewall configuration is with "BLACKLISTNEWONLY=Yes" (see
|
|
|
19 |
# file /etc/shorewall/shorewall.conf). This means that when Fail2ban adds a
|
|
|
20 |
# new shorewall rule to ban an IP address, that rule will affect only new
|
|
|
21 |
# connections. So if the attacker goes on trying using the same connection
|
|
|
22 |
# he could even log in. In order to get the same behavior of the iptable
|
|
|
23 |
# action (so that the ban is immediate) the /etc/shorewall/shorewall.conf
|
|
|
24 |
# file should me modified with "BLACKLISTNEWONLY=No".
|
|
|
25 |
#
|
|
|
26 |
#
|
|
|
27 |
# Enable shorewall to use a blacklist using iptables creating a file
|
|
|
28 |
# /etc/shorewall/blrules and adding "DROP net:+f2b-ssh all" and
|
|
|
29 |
# similar lines for every jail. To enable restoring you ipset you
|
|
|
30 |
# must set SAVE_IPSETS=Yes in shorewall.conf . You can read more
|
|
|
31 |
# about ipsets handling in Shorewall at http://shorewall.net/ipsets.html
|
|
|
32 |
#
|
|
|
33 |
# To force creation of the ipset in the case that somebody deletes the
|
|
|
34 |
# ipset create a file /etc/shorewall/initdone and add one line for
|
|
|
35 |
# every ipset (this files are in Perl) and add 1 at the end of the file.
|
|
|
36 |
# The example:
|
|
|
37 |
# system("/usr/sbin/ipset -quiet -exist create f2b-ssh hash:ip timeout 600 ");
|
|
|
38 |
# 1;
|
|
|
39 |
#
|
|
|
40 |
# To destroy the ipset in shorewall you must add to the file /etc/shorewall/stopped
|
|
|
41 |
# # One line of every ipset
|
|
|
42 |
# system("/usr/sbin/ipset -quiet destroy f2b-ssh ");
|
|
|
43 |
# 1; # This must go to the end of the file if not shorewall compilation fails
