This will make things work, but it is a security hole big enough to fly a
747 through, just in case you care.
Eh? Why? rsh is supposed to be suid-root on any Unix just so it can bind
to a port lower than 1024 and so be "trust-worthy" (well, you can argue with
that :) by other UNIX systems. That's the way it is installed on all our
workstations (Suns, Indigo's, DrekStations etc...).
