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. | |sgi-dogfight 5130/udp # dogfight demo | |WARNING some machines can not handle large numbers of udp |broadcast packets. If you have machines from other vendors |on your network, running dog on your network may bring them |to a halt. VAXes are known to have this problem. Gateways will not transmit udp broadcast packets so you can isolate your other machines by using a gateway. Rob Mace Silicon Graphics
