Answer Posted / achal ubbott
Raw sockets are useful when you want to inject or capture
almost anything(without IP or TCP/UDP headers and the CRC)
on to the ethernet. They operate in Data Link Layer of
TCP/IP model.
Unix/Linux have been supporting them since ages. But
Windows have recentlly stopped their support, because of
security hazards. On windows OS you would have to use
Winpcap network driver library to play with these
sockets.It bypasses the OS's network stack.
