Re: rsh as root
You could try the C3 tools, written by the nice folks at Oak Ridge
National Lab (http://www.csm.ornl.gov/torc/C3/). I have used these
before, as they come with the OSCAR cluster software, and they're very
nice.
Or or perhaps you could simply rely on ssh keys and homegrown scripts. I
haven't used rsh on any of my clusters, I/we use ssh, so we do things thru
ssh keys.
