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 qualied domain name and the password designated in the VNC
server software.
This password doesn’t necessarily correspond to any other password on the system,
and is determined by the VNC conguration.
VNC access is similar to the Control command in Apple Remote Desktop. It lets you 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 clients allow
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.
To allow VNC access:
1 On the client computer, open System Preferences and click Sharing.
If prompted, enter the user name and password of a user with administrator privileges
on that computer.
2 Select Remote Management in the Sharing pane.
If the client computer is running Mac OS X version 10.4 or earlier, change VNC access
by selecting Apple Remote Desktop in the Sharing pane and clicking Access Privileges.
3 Click Computer Settings.
4 Select “VNC viewers may control screen with password.”
5 Enter a VNC password and click OK.
WARNING: Do not use the same password as any local user or Apple Remote
Desktop login.
