Chapter 6 Setting Up the Network and Maintaining Security 83
Avoid using tasks that multicast trac, such as Share Screen and File Copy. File Â
Copy tries to initiate a series of individual copies if there’s a signicant number of
multicast networking errors.
Wireless networks aren’t suited for multicast trac. However the Apple Remote Â
Desktop multi-observe feature is dierent because it doesn’t use multicast trac.
Display shared screens in black and white rather than in color. Â
Congure your AirPort Base Station with a station density of High and increase the Â
multicast rate to 11 Mbps using AirPort Admin Utility. Using the base station density
and multicast rate settings limits the range of each AirPort Base Station network,
requiring client computers to be fewer than 50 meters from a base station.
Getting the Best Performance
To get the best performance when using the Share Screen, Observe, and Control
commands:
Use the fastest network possible. This means favoring Ethernet over AirPort, Â
1000Base-T over 100Base-T, and 100Base-T over 10Base-T.
If you’re using AirPort, adjust the multicast speed higher. Â
Don’t mix network speeds if possible. Â
Reduce the use of animation on remote computers. For example, you can simplify Â
Dock preference settings by turning o animation, automatic hiding and showing,
and magnication eects.
View the client’s screen in a smaller window when using the “t to window” option. Â
View the client’s screen with fewer colors. Â
Use a solid color for the desktop of the screen you’re sharing. Â
Share screens only on local networks. If you share a screen with a computer Â
connected across a router, screen updates happen more slowly.
Set the Control and Observe image quality to the lowest acceptable for the Â
given circumstance.
Maintaining Security
Remote Desktop can be a powerful tool for teaching, demonstrating, and performing
maintenance tasks. For convenience, the administrator name and password used
to access Remote Desktop can be stored in a keychain or can be required to be
typed each time you open the application. However, the administrator name and
password for each client computer are stored in the administrator’s preferences and
are strongly encrypted.
