There is something that can be done to cut down on the flurry of
packets in response to a broadcast.  On all of the 4.2 Unix machines
which are not serving as gateways, turn off IP forwarding in the
kernel.  This will cause them to no longer send ICMP messages or
forward packets that were not specifically addressed to them in the
first place.  Forwarding is controlled by the variable _ipforwarding.
If this is set to zero, these extra packets will not be generated.  On
binary-only systems, you still can turn it off using adb on /vmunix.
