Actually - someone told me to Flame DEC because of a bug in Ultrix 4.0
that is fixed in Ultrix 4.1.

I don't quite agree. Anyone can unplug a machine that isn't in a locked room.
And it's easier to change an IP address that it is to decode a
password from several packets flying across a net. As long as the
ethernet addess isn't cached it would be easier to crack rshd than rexecd.
(Most people turn off their Mac's at night.) Also - the Mac's can
select IP numbers dynamically. If this is done, rshd won't work.

I will agree that Apple should support both protocols, like White
Pine's X server for the Mac.
