Take Control of Screen Sharing in Snow Leopard
Don't buy this ebook! Seriously... you want the Lion edition, even if you are still using Snow Leopard.
This book has been replaced by Take Control of Screen Sharing in Lion. The new edition still has plenty of Snow Leopard details, and it has more current info about Skype, MobileMe, iCloud, and iOS apps.

This book will help you master sharing a remote computer’s screen from Mac OS X 10.6 Snow Leopard (and 10.5 Leopard) and teach you how to get a reliable connection with the greatest versatility. It also explains the use of an iPhone or iPod touch for remote access. It was written by Glenn Fleishman, tech edited by Dan Frakes, edited by Tonya Engst, and published by TidBITS Publishing Inc.
Nearly 20 years ago, working from my desktop computer, I accessed a system that was in a server room but which had no monitor attached. It was magical. I could work with the server just as if I were directly connected with a keyboard and mouse, using its programs and manipulating objects on its desktop—via a 2,400 bps modem!
That sense of wonder still pervades me when I use screen sharing today. Instead of using a 10 Mbps (fast!) local Ethernet network or dial-up software to make the connection, I use broadband feeds over the Internet to reach computers across town or 3,000 miles away.
Screen sharing gives you access to applications and data stored on another computer, even though your keyboard and mouse aren’t connected to that computer. It lets you see a remote computer screen in real time, and it may also allow you to control the remote computer.
Apple extended screen sharing from something you had to install or figure out how to use in Mac OS X 10.4 Tiger and earlier versions of Mac OS X to being part of the system, available on tap, in 10.5 Leopard and 10.6 Snow Leopard.
In Leopard and Snow Leopard, screen sharing comes in several forms, and in this book I explain how to use each of them. In some cases, you must have an account and a password on each machine you want to access remotely. However, one particular method—Screen Sharing over iChat—requires just a buddy who gives you permission, at the time of access, to view or control his or her screen.
I also cover VNC, a technology that’s built into many different programs for many versions of Mac OS X and other platforms, and which is the basis of much of Apple’s screen-sharing functionality. I also explain how to use screen sharing via Skype.
To learn how to set up your Macintosh, iPhone, or iPod touch to view or control the screen of another computer, you’ll benefit from reading Learn the Basics of Screen Sharing carefully, in order to best match your situation to your needs. After that, focus on the material that describes the type—or types—of screen sharing that you want to do. However, if you have specific questions, each section also stands on its own.
I first discuss what you can do and what software you can use. I then explain how to establish your first connection, covering a variety of options. After all that, I provide ideas for handling situations where your Internet connection needs special configuration in order to use screen sharing.
This Snow Leopard edition has several significant changes beyond updating text to reflect new names and updating images to show new interface displays. The major changes are:
Leopard and Snow Leopard: Mac OS X 10.6 Snow Leopard is largely similar to its 10.5 Leopard predecessor, but includes many improved screen sharing-related features. Because Snow Leopard is an inexpensive update and most Leopard users are likely to switch, I’ve reworked this book to indicate which features are new in Snow Leopard and assume that most readers will spend most of their time with Snow Leopard. That said, I indicate wherever possible when features work in both Leopard and Snow Leopard, and provide information about 10.4 Tiger where appropriate, too.

Apple has made a minor revision in the MobileMe preference pane's Back to My Mac tab in Mac OS X 10.6.5. Previously, that tab showed a status dot in red, yellow, or green, along with an explanatory text message, to indicate whether MobileMe was active and communicating correctly with Apple's servers. In this revision, two additional status dots and text messages are added for File Sharing and Screen Sharing. A green dot indicates the service is on; red, off. Putting status about those two items in this tab means you don't have to switch to the Sharing pane to check whether either of those services is active.
