How to change the default port 22 to improve security
Changing the default SSH port (22) reduces random Brute Force attacks on your server.
Heads up
Important: Ensure you allow the new port in the Firewall before closing the current session, otherwise you may lose access to the server.
- 1Step 1
Connect to Server
Connect to your server via SSH using the current port (default 22).
- 2Step 2
Edit Config File
Open SSH config file: `nano /etc/ssh/sshd_config`. Find the line `#Port 22`, remove # and change the number to your new port (e.g., 2222).
- 3Step 3
Save and Restart
Press Ctrl+X, then Y, then Enter to save. Restart SSH service: `systemctl restart sshd`. Make sure to open the new port in your firewall before exiting!
