Screen sharing lets you control the mouse and keyboard of one computer while you sit at another computer across the room or on the other side of the world. It's great for providing remote tech support, configuring and managing a remote server, and collaborating on documents. In recent versions of Mac OS X, Apple has piled on the options, enabling screen sharing via iChat, through Bonjour, directly by entering an IP address, and via Back to My Mac. Plus, Skype has a screen-sharing feature and various iPhone apps can even enable you to control the screen of a remote Mac.

All these screen-sharing choices bring complexity, and Glenn Fleishman's new Take Control of Screen Sharing in Snow Leopard helps you determine the best screen-sharing option for your needs. You'll learn how to configure the software—and set up your router, if necessary. And, should something not work as expected, the ebook also includes problem-solving advice.

This ebook is also available in a discounted bundle with the just-updated Take Control of Back to My Mac, also by Glenn, which goes beyond the basic coverage of Back to My Mac in Take Control of Screen Sharing in Snow Leopard, providing details about how Back to My Mac works behind the scenes, explaining what to do if you can't get Back to My Mac working, and addressing security concerns related to Back to My Mac. Save $5 with the bundle option in the left margin of the Web page for either book.

(If you already own the Leopard edition of Glenn's "Screen Sharing" ebook, look for an email-based update message or open your existing PDF to page 1 and click Check for Updates to access an upgrade discount. If you own Take Control of Back to My Mac, note that the new version is a free update; to get it, use that book's Check for Updates page.)
