RM> Thanx, RM> <mike You don't need a hub or a switch if you have a crossover cable. What Alfred was talking about was that hubs only work in half duplex while switches can (and usually do) work in full duplex. If you have neither, then don't worry about it. With full duplex there is less of a chance for collisions. That is why busier networks use swithes.
