How to set up a linux machine with multiple NICs as a hub/swich?

Hi,

How can I setup a linux machine with 2 or more network cards as a
network switch?

Thanks,
Asfand Yar

Allow me to elaborate on what I'm trying to do:


---------------------------------
| pc1 |

| "virtual" device |
| eth2 ^ |
| | |

| bridged |
| | | |
| NIC <-| --> NIC |
| eth1 eth0 |

| pc2 | -------

As you can see, what I'm really trying to do is to setup my box with 2
NICS to act as a switch between 2 other PCs and myself: i.e. to do the
job of a switch as well its own job.

Before you tell me to go buy a real switch, I know its possible (I'm
doing this more as a scientific exercise than anything else.)

Ideas?

Thanks,
Asfand Yar
