 *   Notes:  
 *   On some systems dropping root capability allows the process to be  
 *   dumped, traced or debugged.  
 *   If someone traces this program, they get control of a raw socket.  
 *   Linux handles this safely, but beware when porting this program.  
 *   An alternative to needing 'root' is using a UDP broadcast socket, however  
 *   doing so only works with adapters configured for unicast+broadcast Rx  
 *   filter.  That configuration consumes more power.
