Comments on How to install Fail2Ban on CentOS 7
Most Linux servers offer an SSH login via Port 22 for remote administration purposes. This port is a well-known port, therefore, it is often attacked by brute force attacks. Fail2ban is a software that scans log files for brute force login attempts in real-time and bans the attackers with firewalld or iptables. This tutorial shows the installation and configuration of Fail2Ban with firewalld on CentOS 7.

No mention of why the action line in the sshd jail is commented out. As long as it is commented, the whole rule is useless.

Hey great article. So many articles had "unban" in the command and not "unbanip" which gave me some grief for 10 mins until I came across your article. Thanks.
