Web site hosting - CHAPTER 8 GETTING EVERYTHING UP AND RUNNING
CHAPTER 8 GETTING EVERYTHING UP AND RUNNING 81 Note To configure most hardware devices, you ll be asked for your password, because configuring hardware requires superuser privileges. Getting Online Getting online is vital in our modern Internet age, and Ubuntu caters to all the standard ways of doing so. Linux was built from the ground up to be an online operating system and is based on Unix, which pioneered the concept of networking computers together to share data back in the 1970s. However, none of this is to say that getting online with Ubuntu is difficult! In fact, it s very easy. Regardless of whether you use a modem, standard Ethernet card, or wireless card, the same program is used to configure your network settings under Ubuntu. Support for many makes and models of equipment is built in, so in most cases, all you need to do is enter a few configuration details. Note Linux actually runs around 60% of the computers that make the Internet work! Whenever you visit a web site, there s a strong chance that it s run using Linux. As your Linux skills increase, you ll eventually get to a stage where you, too, can run your own Internet servers. It sounds difficult, but can be quite easy. Using an Ethernet Card Ethernet is one of the oldest and most established network technologies. When we talk of Ethernet, we refer to wired networks all the computers on the network are connected by cabling to a central hub or router. (The other form of networking technology, which works without wires, is covered in the next section.) You might go online via an Ethernet card in a variety of situations. If you have DSL or cable broadband service at your home or workplace, for example, you might use a DSL router. Your computer will then connect to this router via Ethernet, and all you need to worry about on your PC is getting your Ethernet card up and running. Note Using a DSL or cable modem router is the preferred way of going online via broadband. However, some people use USB-based DSL modems, which connect to and are operated by their PC. These are covered in the Using a USB-Based DSL Modem section later in this chapter. If you re running Ubuntu on a PC in an office environment, it s likely that you will connect to the local area network using an Ethernet card. This lets your computer communicate with other computers, as well as with printers. In some offices in which an Internet connection is provided, this connection will allow you to go online.
