udp packets
 

Uhm. Was wondering, how do you make and send an arbitrary udp packet? To make it simple(r), say I want to send a blank udp packet to 127.0.0.1. How would I accomplish this? Would I just open up a raw socket and send some quirky binary code?

Use socket() to create a SOCK_DGRAM socket, then use sendto() to send a packet... I think it will accept a 0 length buffer, but if not just send a single character.
