Getting it all to work can be a bit tricky, but it is definitely worthwhile. The easiest way is just to hook them both up to your router, then the setup is pretty much automatic. If you have to use a crossover, or a hub, but no router, then yes you have to set everything manually on each machine. There are plenty of guides around the net for that so I won't duplicate it here. But, in the end, it is a less work just to go buy what you need to hook them all up to your router.
