Tool for source routing

[Franklin DeMatto <franklin () qDefense com>]

Can anyone suggest a good tool to perform ip addr spoofing via source routing?

That is, it should replace the source addr with a spoofed one, and add the 
real one as a source route.  It must also forward the recieved packets, 
since their dest addr will be the spoofed one.

It should ideally be able to sit in between other apps, both ones that use 
connect() and ones that use raw sockets, and modify the IP packets to 
source route.  This would allow use of preexisting tools without 
rewrite/recompilation.

BTW, I'm mainly interested in using it on Linux 2.2 systems.  If this can 
be done with ipchains, could someone suggest how?
