This is an SSH issue, not a Fabric specific one, FYI. If you're asking
about what the SSH best practice is, typically you might set up a
normal user on the remote end who has "sudo" privileges (so they can
do root-y things when necessary) and then connect as that user. Having
the root user turned off for SSH logins is typically a good thing to
have security-wise.

You can also use SSH keys and an agent (on your local workstation) to
get passwordless logins to servers that are configured correctly.
Google around for "ssh key authentication" :) there's a million
tutorials out there.

Hope that helps,
Jeff
