Virtual Network Computing Access You can use Apple Remote Desktop to access a Virtual Network Computing (VNC) server and view and interact with the server's screen. VNC access is determined by the VNC server software. To access a VNC server, it is only necessary to know the IP address or fully qualified domain name and the password designated in the VNC server software. This password does not necessarily correspond to any other password on the system, and is determined by the VNC configuration. VNC access is similar to Apple Remote Desktop's Control command. It allows you to use your keyboard and mouse to control a VNC server across a network. It doesn't give any other Apple Remote Desktop administrator privileges except those of the currently logged-in user. Non-Apple VNC viewers can control Apple Remote Desktop clients if the client allows it. Allowing a non-Apple VNC viewer access to an Apple Remote Desktop client is less secure than using Apple Remote Desktop to control the client. The VNC protocol implemented in third-party VNC viewers may not encrypt keystrokes sent over the network, so sensitive information can be intercepted. WARNING: Granting VNC access to control a screen is the most powerful feature in Apple Remote Desktop, and can be equivalent to unrestricted access. 74 Chapter 5 Understanding and Controlling Access Privileges

Each of these features can be enabled or disabled independently of each other, or you

can enable all of Remote Desktop’s features for nonadministrator users.

To enable User Mode:

Make sure you are logged in as an administrator user.

Open Remote Desktop.

Choose Remote Desktop > Preferences.

Click the Security button.

Select “Access restricted to the following features” and enable or disable features, as

desired.

Close the Preferences window.

Virtual Network Computing Access

You can use Apple Remote Desktop to access a Virtual Network Computing (VNC)

server and view and interact with the server’s screen. VNC access is determined by the

VNC server software. To access a VNC server, it is only necessary to know the IP address

or fully qualified domain name and the password designated in the VNC server

software.

This password does not necessarily correspond to any other password on the system,

and is determined by the VNC configuration.

VNC access is similar to Apple Remote Desktop’s Control command. It allows you to use

your keyboard and mouse to control a VNC server across a network. It doesn’t give any

other Apple Remote Desktop administrator privileges except those of the currently

logged-in user.

Non-Apple VNC viewers can control Apple Remote Desktop clients if the client allows it.

Allowing a non-Apple VNC viewer access to an Apple Remote Desktop client is less

secure than using Apple Remote Desktop to control the client. The VNC protocol

implemented in third-party VNC viewers may not encrypt keystrokes sent over the

network, so sensitive information can be intercepted.

WARNING:

Granting VNC access to control a screen is the most powerful feature in

Apple Remote Desktop, and can be equivalent to unrestricted access.
