interfaces could be connected to another computer or even an entirely different network. By<br />

enabling Internet sharing, you’re able to let the computers on one network interface connect to<br />

the Internet on another.<br />

For example, a typical setup might have the Internet coming into your home via a cable or<br />

DSL modem, which, in turn, is connected to an AirPort base station. All the computers in your<br />

home would then be connected to the AirPort base station, sharing its Internet connection.<br />

With Internet sharing, you could instead plug one computer directly into the modem via<br />

Ethernet and then use that machine’s AirPort card to create an ad hoc network that other computers<br />

could use to share the Internet connection, eliminating the need for the AirPort base<br />

station altogether.<br />

This kind of setup is particularly convenient when you are away from home. If your hotel<br />

room has an Internet connection via Ethernet, several people can share that connection without<br />

having to pack an AirPort base station or other network hardware.<br />

Bluetooth Sharing<br />

Although it’s usually associated with headsets and other simple gadgets, Bluetooth is a general<br />

short-range wireless standard that can connect two machines with file systems, such as two computers,<br />

or a computer and a phone. To move files around over a Bluetooth connection, you’ll<br />

need to enable Bluetooth sharing, though connecting a Bluetooth device will usually activate<br />

Bluetooth sharing for you.<br />

Summary<br />

CHAPTER 21 WORKING WITH REMOTE SERVERS AND NETWORKS 381<br />

When it comes to connecting to remote machines, you have a lot of options. Networking is built<br />

into the Finder, and .<strong>Mac</strong> takes this even further, integrating the entire web publishing experience<br />

into the <strong>Mac</strong>’s legendary interface. Third-party applications expand this integration by offering<br />

direct connections to the Internet, either through .<strong>Mac</strong> or by directly incorporating Internet technology<br />

such as FTP and Secure Shell.<br />

Networking is no longer a one-way street with clients and servers having immutable, predefined<br />

roles. Any <strong>Mac</strong> has the pedigree of a server built right into System Preferences, whether it’s<br />

to simply share a file, to allow remote access to the machine, or to take on a more permanent<br />

role.<br />

In the next chapter, we’ll explore a particularly common sharing scenario: setting up a web<br />

server on your <strong>Mac</strong>. Whether creating an intranet, building a test platform for development, or<br />

hosting a web site from your home or office, you’ll see that serving web pages on <strong>Mac</strong> <strong>OS</strong> X is<br />

easy to do but endlessly configurable.
