I don't think there's anything difficult about setting up rsh, ssh or
kerberos for anyone who know how to read a manual. A newbie shouldn't be
setting up a cluster in the first place. That's advanced kung-fu best
left to the black belts. Letting a neophyte build and run an HPC cluster
is some kind of oxymoron.

Yes, I know that professors usually tell some green graduate student to
go build a cluster for the dept, but that's a completely different topic
outside the scope of this list...
