Virtual Network Computing (VNC) Access
You can use Apple Remote Desktop to access a 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 with any other password on the system,
and is determined by the VNC configuration.
VNC access is similar to ARD’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 ARD
administrator privileges except those of the currently logged in user.
Non-Apple VNC viewers can control ARD clients if the client allows it. Allowing a non-
Apple VNC viewer access to an ARD client is less secure than using ARD to control the
client. The VNC protocol does not encrypt keystrokes sent over the network, so
sensitive information can be intercepted over the network.
To allow VNC access:
1 On the client computer, open System Preferences and click Sharing.
On Mac OS X 10.2 clients, select the Remote Desktop pane and skip to step 4.
If necessary, enter the user name and password of a user with administrator privileges
on that computer.
2 Select Apple Remote Desktop in the Sharing Methods pane.
3 Click Access Privileges.
4 Select “VNC viewers may control screen with the password.”
5 Enter a VNC password.
Warning: Granting VNC access to control a screen is the most powerful feature in
ARD, and can be equivalent to unrestricted access.
Warning: Do not use the same password as any local user or ARD login.
