Raw Sockets

Raw Sockets let you program at just above the network (IP) layer You could program at the IP level using the IP API but you can’t get at ICMP Raw Sockets expose ICMP you get a Raw Packet and populate the entire packet yourself for high level protocols like TCP and UDP you lose all of the functionality implemented in those layers choosing to use a Raw Socket must be weighed carefully Raw Sockets can be dangerous Raw Sockets can be against the law http://www.kumite.com/rsnbrgr/rob/grcspoof/cnn/ ...
