I run a small LAN in my home. It has a desktop running Windows XP, a laptop running Vista Home Premium, a "netbook" running Linux (Ubuntu Intrepid Ibex) and my iPod Touch running s/w 3.0. The whole thing is networked wirelessly via a Netgear router which aslo acts as a DHCP server. I have allocated hostnames to each machine. The three computers can refer to each other by hostname as well as by IP address. The iTouch doesn't understand the names. Why not? How do I make it play ball?
