If you are hosting your ssh server to public, please remember to disable the root access. This is important! A lots of “hacker”s are running brute force tools trying to scan the open ssh port and brute force to get root access. If your root password somehow easy to guess, or you are not lucky enough, your server will be “hack” and become a phishes machine.
How to disable the root access?
Edit /etc/ssh/sshd_config, search for PermitRootLogin and change the yes to no. Then restart ssh server
sudo /etc/init.d/ssh restartDon’t take the risk to enable root access, unless you are sure what are you doing. If you need root access, consider to use sudo.
