Hi,
I am trying to understand the implementation of linux 2.4 and linux
2.6's networking (IPV4) . Can anyone give me some idea/pointers about
some of the good resources/whitepapers available in the market to
understand the same. If there is any document that mention the changes
between the implementation of networking in 2.4 & 2.6
I am also trying to write a simple program(preferably a userspace
application) which captures all the incoming and outgoing packets of a
particular machine (preferably at PREROUTING stage), then according to
the SRC/DST addresses, changes the IP address of some of the packets
and then reinject it back into the local IP stack. I am able to do
that in 2.4 kernel by using libipq and ip_tables but that prog is not
running in 2.6 kernel. (It hits at ip_route_BUG). Any idea or code
snippet will be really appreciated.

You may also see the information on the linux-net wiki:
http://linux-net.osdl.org/index.php/Main_Page.
Also, read some threads on netdev list. It has a lot of information
there too.
