How do I disable root ssh login?

Before you do this make sure you have created another user in the wheel group.

To add a user to the wheel group, run the following commands from the root shell:

# adduser testuser     (adds the user)
# passwd myuser    (sets the new user's password)
# usermod -G wheel testuser    (adds the new user to the wheel group)
To disable root login through ssh, edit the following file:

 
# /etc/ssh/sshd_config
browse to the following line:


PermitRootLogin yes
and change to:


PermitRootLogin no
Save the file and restart ssh.


# /etc/init.d/ssh restart
If you are ssh'd into the server with root when this is done, your connection will fail on the restart of ssh.
