VPS Guide: Your Go-To for VPS, Ubuntu & Command Line Success

Set Up UFW Rate Limiting on Ubuntu

Category: VPS Setup

Limit SSH connection attempts with UFW on Ubuntu—install with

apt install ufw

then add a rate-limiting rule:

ufw limit ssh

(or ufw limit 2222/tcp for a custom port) This allows 6 connections per 30 seconds per IP blocking excess attempts—enable with

ufw enable

Check with

ufw status

expecting \"22/tcp LIMIT Anywhere\" Pair with Fail2ban for bans—test by running multiple

ssh user@ip

attempts from another machine; expect blocks after 6 On Vultr this protects MySQL and phpMyAdmin from brute-force maintaining uptime—view logs with

cat /var/log/ufw.log | grep LIMIT

for blocked IPs
