Hello Kirti, rather than doing it in kernel space why don't u do in userspace. There's a lot of tools and libraries available! Take for example tcpdump, ethereal, dniff and others as tools, libpcap (*nix packet capturing library) or wincap (windows packet capturing library) and many more. The kernel also provides a lot of other features via the socket call to do these stuff. Could u please detail out what exactly do u want to do and your major reason of getting inside the kernel ?
hope this helps.. mal -------------------------------------------------------------------

Do it in userspace with packet filters. Look at tcpdump for example code. Rasmus
