We are on a mostly trusted network with little user access to the
systems. I
just needed a right now solution while I look into useing ssh as a
replacement
for the rcmd rcp stuff.

one question that might be a good one. I have only ever used ssh as a
replacement
for telnet and never really looked into all of its functionality. can
it be a drop in
replacement for the r* commands? if i crated links from rcp -> scp and
rcmd -> ssh
will scripts still run? and how do I go about authintication for
replaceing the .rhosts
files? I guess I will be rtfming on this for a while so don't bother
answering all this
except maybe the drop in replacement stuff.
