[CentOS] 'root' ssh login

[Benjamin Smith]

I changed the port from 22 to a random high port (> 1024) and disabled root 
login with passwords in /etc/ssh/sshd_config: 

PermitRootLogin without-password 

Since doing these, I've had zero problems with dictionary attacks and the 
like. 

I've had a page bookmarked since forever ago, that explains keys:
