udp packet storms

[newsham () zang kcc hawaii edu (Tim Newsham)]

There's at least one way to make a UDP packet storm.  Not
very hard to do:

   src address = 255.255.255.255 port 7
   dst address = <some host> port 7

the port will be echoed by the inetd (echo port) back to the
sender (255.255.255.255 port 7).  Each machine with an inetd
that has echo enabled will echo the packet back to the first
machine.  Broadcast addresses need not be used:

  src address = <some host> port 7
  dst address = <some other host> port 7

I imagine the same can be done with talkd packets.  UDP source
addresses are easy to forge.
