What is fail2ban?
fail2ban is a security tool for Linux servers that helps prevent brute-force attacks. It works by monitoring log files for suspicious activity (like repeated failed login attempts) and temporarily banning the offending IPs via iptables, firewalld, or similar mechanisms.
Why use fail2ban?
– Automatic protection against common attack patterns
– Highly customizable filters and actions
– Lightweight and easy to integrate into existing systems
Why this script?
I found myself constantly forgetting the exact commands for managing jails, viewing logs, or unbanning IPs. Rather than memorizing everything or digging through man pages, I wrote a small helper script to streamline the process.
It wraps common fail2ban-client operations into a set of clear, quick commands.
