Connecting to Your Macs
Email and Web surfing may be the most popular Internet activities, but the world's most gigantic network can also help you stay in touch with your Macs back home when you're on the road. Mac OS X offers a few tools for manipulating your Macs, including remote access technologies like long-distance file sharing and SSH (a geeks-only program that you'll learn more about in a moment).
Note
These techniques are designed for full-time Internet connections (cable modem or DSL, for example). If you have a dial-up modem, these features work only when you're actually online. Still, they may occasionally be useful even when you're not. You could always call up a friend and say, "Check out my Web site right now—here's the current IP address" or call someone back home to say, "I have to grab a file off my hard drive. Could you make the Mac on my desk go online?"
