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.
