In the Control/Observe pane, you can set:
• Whether control of the mouse and keyboard is shared with the client computer
when the client is controlled
• Whether a remote screen is shown at its actual size in a window or if it shrinks to fit
the window
• Whether remote screens are shown in color or black and white
• How many computers can be observed on one page
• Image quality for observing multiple screens
In the Data Collection pane, you can set:
• Where the saved data for reports resides
• Whether other ARD administrators can access your local report database
In the Restricted Access pane, you can set:
• Which features of Remote Desktop are available to non-administrator users
See “Limiting Features in the Administrator Application” on page 51.
Setting Up the Network
Your network configuration determines Apple Remote Desktop’s performance and
usability. AirPort and AirPort Extreme networks offer slower performance than almost
any Ethernet network. Therefore, file copying, client monitoring, and reporting will be
slower over AirPort and AirPort Extreme connections. Network routers and firewalls also
shape, direct, or block network traffic; these things can have an effect on ARD’s
reliability and efficiency. Here are a few guidelines to keep in mind when setting up
ARD on your network:
• The more AirPort clients are connected to a base station, the lower the bandwidth
for each computer. AirPort Base Stations are not considered “switched networks.”
• Bonjour does not extend beyond the local subnet. Bonjour names do not resolve
across routers like domain names do.
• Networks with switches have fewer collisions and packet errors than networks with
hubs. This means greater reliability and speed.
• If network traffic will pass through firewalls, make sure you have a large Maximum
Transmission Unit (MTU) setting (1200 or greater). Too small an MTU setting can result
in black screens when sharing or sending screens.
• If you are going across a wide-area network (WAN), or metropolitan area network
(MAN), make sure that the defrag bit is turned off in your router so packets don't get
chunked up. This can result in black screens when sharing or sending screens.
• NAT (Network Address Translation) networks (such as those that use the Mac OS X
“Internet Sharing” feature) can pose configuration and access difficulties.
