How to Change Your SSH Port

Changing the default SSH port from 22 to a custom port can help reduce automated login attempts. This article explains how to change it on a Linux server.

Important Note

Changing the SSH port is not a replacement for strong authentication. Always use strong passwords or SSH keys, and consider a firewall.

Changing the Port

  1. Log into your server via SSH.
  2. Open the SSH configuration file: 
    sudo nano /etc/ssh/sshd_config
  3. Find the line #Port 22 and change it to your desired port, for example: 
    Port 2222
  4. Save the file and exit.
  5. Restart the SSH service: 
    sudo systemctl restart sshd
  6. Update your firewall to allow the new port.

Connecting to the New Port

ssh -p 2222 username@your-server-ip
