Fail2ban turns that noise into action: it watches your log files, spots the pattern of repeated failures from a single IP, and tells the firewall to ban that address for a while. It is the automated bouncer for your VPS, and on Ubuntu 22.04 it takes about ten minutes to set up properly. This guide installs it, configures a tuned SSH jail, and verifies that bans actually fire.</p>
