Hi all,

I've to build a protocol RSVP-like.

When I send a packet from application A to application C, through host
(router) running application B, B have to see the packet and to modify
it.
I know it's possible with Raw Socket. But I'm not able to do it.

How do I say to IP that B has to receive the packet with another
destination address?

Are there tutorials around the net about Raw Sockets?

Thanks,
Marcello.

Check out IP spoofing and other DOS attacks...that should have the code to
re-construct a packet with a false return address..
