Chapter 22. SSH, FTP, VPN, and Web Sharing

Email and Web surfing may be the most popular Internet activities, but the world's most

gigantic network has many other uses. The general idea is always the same, though:

letting one computer reach out and touch another.

Mac OS X offers a few features that embrace the more literal aspects of that notion. For

example, you can turn your Mac into a Web server—an actual living Web site that

anyone on the Internet can visit. This chapter also explores various advanced methods of

manipulating your own Mac from the road, including remote access technologies like

long-distance file sharing, FTP, SSH, and virtual private networking (VPN).

Note: Most of these technologies 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 anyway. You could

always get online, 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?"

22.1. Web Sharing

Using the Sharing pane of System Preferences, you can turn your Mac into a Web site (or

server), accessible from the Web browsers of people on your office network, the Internet

at large, or both.

This feature assumes, of course, that you've already created some Web pages. For this

purpose, you can use Web design programs (Macromedia Dreamweaver, for example, or

the free Netscape Composer) or save documents out of TextEdit or Word as Web pages.

Or you could let Mac OS X build Web pages for you using iPhoto or Image Capture.

After you provide your friends and co-workers with your Mac's Website address, they

can view your Web pages, graphics, and documents in their own Web browsers. And

whenever you're online, your Web site is also available to any one on the Internet—but

you don't have to pay a penny to a Web-hosting company.
