The dog program on our Irises uses xns instead of tcp/ip.  If
xns is not installed you will get the Ethernet init failed message.
A tcp/ip version has been around for about 2 years now
(thanks Andy and others...), but I don't know if sgi
has it or ships it for 3000s.  The Personal Iris that is here on
demo has dog, and I believe that it uses tcp/ip.

One problem with the tcp/ip version of dog is that it
sends broadcast messages all over the ether.  This can
cause severe problems to remote machines, in particular,
vaxen.  I think I saw this documented in the 4D20 documentation
somewhere.  Anyway, I fixed our 3000 version so it only sends to machines
that it knows about.
