Secure Shell (SSH) allows HostPapa VPS users to log in and manage their server using a command-line application, such as Terminal on Mac OS and Linux, or a third-party application like PuTTY on Windows. SSH communications typically operate over port 22, but if you wish to tighten security, you could change the SSH port to an alternative. Use the following steps to change the SSH port for a Linux server.
Log in to your VPS server using SSH, using Terminal or an alternative SSH command-line app. You should log in with the root administrator.
Once logged in, run the following command:
The SSH configuration file will open. Locate the following line:
# Port 22
Type i to enter the vi text editor’s Insert mode. Delete the “#” and change the port number to an alternative. Press Escape to return to vi’s Command mode.
Type “: x” (without the space) to save the file and quit the vi text editor.
Now run the following command to restart the SSH service on your server with the new port number.
service sshd restart
