Sure!  You need two things:  (1) a "crossover" ethernet cable, and (2) the
server has to be setup as a router.  I believe that you can setup Linux as a
router, although I'm not sure how.

As for the cable, I'm assuming you're using regular ol' twisted pair (RJ45
connectors, 8 wires).  I think you can buy these cables at any computer
store.  Basically, there are two recieve wires and two transmit wires.  When
you connect to a hub, the hub will conenct the transmit and recieves for
each
port for you.  In a direct connection, you need to make the connection, and
that's what the crossover cable does.

Each RJ-45 has 8 pins/wires.  Basically, NIC cards only uses 4 of the wires,
namely pins 1, 2, 3, and 6.  If you hold the connector with the spring clip
down, pin 1 is on the left.

For a crossover cable, you connect:

Pin 1 --> Pin 3
Pin 2 --> Pin 6
Pin 3 --> Pin 1
Pin 6 --> Pin 2

You can ignore the rest of the pins.

More information then you wanted, right?  ;)
