Configure Fail2ban
Fail2ban configuration files reside in
/etc/fail2ban. The default configuration file is called jail.conf, which should never be edited by hand because future updates will rewrite this file. Instead, create a new configuration file called jail.local. Any values here will override the default values.Change working directory to fail2ban and open the default config jail.conf
[root@localhost ~]# cd /etc/fail2ban/
[root@localhost fail2ban]# ls
action.d filter.d paths-common.conf paths-freebsd.conf
fail2ban.conf jail.conf paths-debian.conf paths-opensuse.conf
fail2ban.d jail.d paths-fedora.conf paths-osx.conf
[root@localhost fail2ban]#
[root@localhost fail2ban]# vi jail.conf
[root@localhost fail2ban]#
Change directory to jail.d and create config file
[root@localhost fail2ban]# cd jail.d/
[root@localhost jail.d]# ls
00-firewalld.conf
[root@localhost jail.d]# vi sshd.local
[root@localhost jail.d]#
Example of configuration
Start the fail2ban service and check the service status
[root@localhost jail.d]# cat sshd.local
[sshd]
# To use more aggressive sshd filter (inclusive sshd-ddos failregex):
#filter = sshd-aggressive
port = 2222
logpath = %(sshd_log)s
backend = %(sshd_backend)s
enabled = true
# bantime in seconds
bantime = 86400
