[ale] Ssh config question

[DJ-Pfulio]

Looks like the ALE mail server is running a day or 2 behind again. ;(

The ~/.ssh/config file is just for remembering stuff - it doesn't actually
change any server-side settings. That is in /etc/ssh/sshd_config - Port.

If you didn't place the public key on the remote machine under each userids
HOME, then it won't work.

Since it is a best practice to refuse remote root connections, I setup
root-equiv accounts with key-only access for backup use.  But when using tar,
that isn't really needed - the archive will have the own/group/permissions
inside already.

Lastly, I'd only use tar for very small directories, not for whole system backups.

Hopefully this all makes sense.
