Is setting up automatic login for each ssh-connected machine required?  
User 'root' is usually not allowed to log into another machine using ssh. In 
this case, what do people usually do to run fab files?
Thanks again.

Fabric is simply an SSH wrapper, so it requires absolutely nothing on
the *server* end save for SSH itself. (Contrast this to tools like
execnet which *do* require Python on the server end.) You can install
Fabric on a single workstation and write/run Fab scripts targeting any
number of servers; that's the common use case at any rate.

If I've misunderstood your question, let me know.
