Chapter 18.
If your UNIX system is in an office with an Ethernet LAN or you have a home network with a router, you can usually put your system on the net with little effort. When most UNIX software is first installed, it asks whether you have a LAN connection. Make sure a network cable is plugged from your computer to the LAN hub or router and tell the installation software that yes, there’s a LAN. (Um, well, yeah, that’s kind of obvious.) If it asks whether you want to get your network address automatically, dynamically, or using DHCP, three increasingly geeky ways of saying the same thing, also say yes. Barring bad luck, your computer automatically connects to the local network each time it starts up.
