Quote:Step Five — Configure SSH

Now that we have our new account, we can secure our server a little bit by modifying its SSH configuration (the program that allows us to log in remotely).
Begin by opening the configuration file with your text editor as root:

Code:

nano /etc/ssh/sshd_config

Change SSH Port (Optional)
The first option that you may want to change is the port that SSH runs on. Find the line that looks like this:

Code:

Port 22

If we change this number to something in between 1025 and 65536, the SSH service on our server will look for connections on a different port. This is sometimes helpful because unauthorized users sometimes try to break into servers by attacking SSH. If you change the location, they will need to complete the extra step of sniffing it out.
