Ah, no. Where can you log in as root from? If it's anywhere outside the
intranet, bad, bad, bad. Thre's been reports that the serious encryption
keys can be cracked in a very short time, thanks to an account on Amazon's
cloud. Here at work, you can only log in as root *from* *the* *console*;
anything else, it's either via ssh keys, or as yourself, then sudo (or
sudo -s).

When I have more than one machine at home, I *only* allow ssh from the
internal net, and *never* from outside.
