The Internet is fast becoming a lifeline for most of us. It seems we can't get by a day without it. I know I could not write the book without it. Sometimes I wonder how we ever managed without the Internet. You'll no doubt want to connect your Red Hat Linux system (and perhaps your own LAN) to the Internet. In this chapter, I show you how to connect to the Internet in several different ways-depending on whether you have DSL, a cable modem, or a dial-up network connection.
Two of the options for connecting to the Internet-DSL and cable modem-involve connecting a special modem to an Ethernet card on your Red Hat Linux system. In these cases, you have to set up Ethernet networking on your Red Hat Linux system. This chapter shows you how to set up a DSL and a cable modem connection. I also describe dial-up networking, which involves dialing up an Internet service provider (ISP) from your Red Hat Linux system.
As you read this chapter, consult Chapter 6 for discussions of networking, TCP/IP, and the Internet, as well as for terms such as Request for Comments (RFC).
