Use rsa/dsa keys and disable password auth in sshd_config.

You can generally do port upgrades via ssh without issue. Obviously you
have to be careful when performing major updates like `make world` where
it's usually recommended that you drop to single-user mode before
installing world. Some folks claim they do the whole make world dance by
remote and just don't reboot or drop to single-user mode. Personally,
I'd never do this on a production box but I recall some good discussion
on this list a few months ago about this very topic. Check the archives
if you're interested.
