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 ------------------------------------------------------------------- On Sun, 14 Oct 2001, Mehta, Phoram Kirtikumar (UMKC-Student) wrote: > 1. how does ifconfig and netstat get teh net statistics, where can i get > the source to that funtion or source file.

Do it in userspace with packet filters. Look at tcpdump for example code. Rasmus ===== Image by FlamingText.com __________________________________________________ Do You Yahoo!?
