You probably need a cross-over cable.
When connecting to a hub, you normally use a "straight-thru" cable. If you
want to connect two computers directly to each other, you need to use a
"cross-over" cable. This cable reverses the leads and so that the "send"
signal on system A goes to the "receive" on system B (and vice versa). If
you are connecting via network hub, it automatically does this for you.
If you only have two systems that you want to connect, you could make (or
buy) a cross-over cable. For making a cable, I don't remember the exact
pins to connect, but a quick web search for "RJ45 network crossover cable"
should turn up some useful info. If you need to connect more than two
systems, it would be best to use a hub (and then you can use regular
straight-thru cables).
