Secure Your SSH Access

To restrict and secure SSH access, bind sshd to a single IP that is different than the main IP to the server, and on a different port than port 22.

SSH into server and login as root.

At command prompt type: pico /etc/ssh/sshd_config

Scroll down to the section of the file that looks like this:

#Port 22
#Protocol 2, 1
#ListenAddress 0.0.0.0
#ListenAddress ::
