Disabling root login via SSH (CentOS)

This specifically applies to Centos 5.x

# <span style="text-decoration: underline;">vi /etc/ssh/sshd_config</span>

Preferably do this on a second login if you have to do this on a remote system... and keep the one of them open! All you have to do is locate the line "PermitRootLogin yes" and change it to:

PermitRootLogin no

Then restart SSH:

# <span style="text-decoration: underline;">/etc/init.d/sshd restart</span>
