How to change the SSH port

Question

How do you change the SSH port?

Answer

1. Configure any firewalls that may restrict traffic to the server to allow traffic for the new SSH port.
2. Access the server's command line as the 'root' user via Terminal in WHM or a remote console.
3. Open /etc/ssh/sshd_config in your preferred text editor.

4. Locate the "Port" line.

   Note: If the line does not exist, it must be added. 
   If the line is commented out (# at start of line), it must be uncommented.

5. Set the "Port" value to the desired port number:

   CONFIG_TEXT: Port $portnumber

   Note: "$portnumber" must be replaced with the desired port number.

6. Restart the SSH service:

   # /scripts/restartsrv_sshd
