1. Intercepting IP packets without kernel intervention

Hi,

I am trying to intercept IP packets
and dispatches them myself. I don't
want the kernel to do processing on the
packets that I have captured.

By using raw sockets or by accessing the link
layer, I can intercept an IP packet, but how
do I block the kernel from processing it ?

Is it possible to do it from a user level
program, or do I have to write a kernel module ?
Whatever the case maybe, could somebody please
provide me with some pointers, where I can find code
and examples ?

I am using FreeBSD 2.2.8 and Linux (RedHat 5.1).

thanx in advance,
-- Areef.
