How to change default SSH port?

Everyone knows 22 is the default SSH port. So it’s always good to change this default port and set it to something unguessable. Please follow the below steps.

Here we are going to change the port to 4242. Edit the main SSH configuration file.

vi /etc/ssh/sshd_config

You can find the below line.

#Port 22

Change it as below.

Port 4242

Restart SSH to update the changes.

/etc/init.d/sshd restart

That’s it!! You have changed the SSH port to 4242. :)

To login as “sshusr” from a remote Linux machine you can run the below command.

ssh [email protected]/Hostname -p 4242
