dog and arena currently use udp broadcast to communicate.  Some machines can
not handle large numbers of udpbroadcast packets.  To do a udp broadcast
there must be a line in the file /etc/services.  By default this line
is commented out.  If you try to run dog without this line it prints
the following message.
|To run dog over the network you must have the following line
|in your /etc/services file.

Gateways will not transmit udp broadcast packets so you can isolate your
other machines by using a gateway.
