Hi,
I'm new to the list, and I haven't found my question in the mirror, and I
couldn't find what I was looking for in the faq, so I would like to ask a
question.
So my assignment would be the following:
I have two network cards in a machine. So the two network cards are on the
same physical network, and the subnet is the same. Another machine is on
the same physical network, also with two network cards:
__________________________________________________________

10.10.10.1 10.10.10.2 10.10.10.3 10.10.10.4
NodeA NodeB
The route on NodeA goes through 10.10.10.1, to 10.10.10/24. What I would
like to reach is to somehow make packets go through 10.10.10.2 to
10.10.10.3. My guess was to use raw packets, and there is an option that
can tell a mandatory route for a UDP packet, at least that's what I read
in Tanenbaum's Computer Networks. Would that work for this case? So that
the first route would be 10.10.10.2, and the next one is 10.10.10.3. If it
worked, how can I do so? I read all kinds of documents, but nothing
details the TCP protocol at this level.
I don't have any routers, just that single 10Base2 wire, and they have to
be on the same subnet. I can't use ipchains either because it should be a
portable code.
Any doc advice or .c fragment would be highly appreciated.
Thanks in advance, Ferenc
