I have a linux box setup with 2 3com ethernet 905 cards. One of the cards
(eth0) is connected to my local net and functioning correctly, I would
like to attach another machine to the other card via a crossover cable,
and use that card as a hub/switch (so I can connect to the network with
the other machine as tho it were connected to a hub/switch along side of
eth0) Basically I'm trying to use bridging to emulate/create substitute as
a hub or switch. I have both interfaces functioning (they work if i
ifconfig eth1 to 10.0.0.1, set the machine on the other end to
10.0.0.2, setup ipmasq etc, setup the default route and eth0 to a
registered ip on our LAN and I can masqerade out) however I would like
to make the other machine appear to be a real IP address on the LAN. What
is the best way to do this, be it bridging/switching in the linux box, or
some sort of ip translation?

Sorry if this is foggy, but I'm not sure what I should be doing to
accomplish what I'm trying to do :P I've tried setting up bridging
(compiled bridging into the kernel, downloaded what appears to be a very
old copy of brcfg-0.1 and:
# ifconfig eth0 some.registered.ip.address up promisc
# ifconfig eth1 up promisc
# ./brcfg -ena
Doesnt seem to work. Whether thats because I'm misusing bridging for
something its not supposed to do, the bridging tool I have is
old/incorrect, or I'm plainly an idiot I'm not sure :-)
