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.

  1. Stop your problem instance
  2. Paste this script in Instance Settings > View/Change User Data
  1. Start your instance and now you should be able to SSH.
