Currently, I locked myself out of my VPS (Amazon EC2) after configuring ufw firewall. Here are what I've done to disable ufw and take back the control of my VPS.
- Stop your problem instance
- Paste this script in
Instance Settings > View/Change User Data

#!/bin/bash
ufw disable
iptables -L
iptables -F
--//
- Start your instance and now you should be able to SSH.
