How to change ssh port on my Shell?

For security reasons it is recommended to change the default SSH port 22.

To do so, open /etc/ssh/sshd_config configuration file with any text editor:

sudo vi /etc/ssh/sshd_config

You should see the following:

Change port 22 to any number above 1024 and save configuration file:

- Click Esc

- Type :wq

- Click Enter

Add your new port into firewall rules:

sudo ufw allow *port number*

Now you are able to ssh into your Shell using a non-default port.
