Install Fail2ban with Ban Action on Ubuntu

Category: VPS Setup

Customize Fail2ban ban actions on Ubuntu—install with

apt install fail2ban

then edit /etc/fail2ban/jail local with

nano /etc/fail2ban/jail.local

[sshd]\nenabled = true\nport = 22\nfilter = sshd\nlogpath = /var/log/auth.log\nmaxretry = 5\naction = iptables[name=SSH, port=ssh, protocol=tcp]\nbantime = 3600

Restart with

systemctl restart fail2ban

open SSH with

ufw allow 22

Test with failed logins—check

iptables -L -n

for \"DROP\" rules and

fail2ban-client status sshd

for bans On Hetzner this uses iptables directly—ensure MySQL and phpMyAdmin uptime with precise SSH protection for 1 hour (3600s)
