Chapter 6: Setting Up VNC Server
Stopping VNC Server
VNC Server runs until it is stopped.
To explicitly stop VNC Server:
• In all modes and under all platforms except Virtual Mode on UNIX/Linux, select Stop VNC Server from
the VNC Server shortcut menu. More on this menu. Administrative privileges are required to perform this
operation.
Note: Under Windows, VNC Server in Service Mode will not automatically restart if you do so and then
reboot the host computer.
• To stop VNC Server in Virtual Mode, run the command vncserver -kill :x, where x is the X Server
session number. For more information, see page 75.
Note that VNC Server automatically stops:
• In Service Mode (Windows and Mac OS X) and in Virtual Mode (UNIX/Linux), when the host computer is
powered down.
• In User Mode (all platforms), when the host computer starting it logs off or the host computer is powered
down.
VNC Server can also stop under the following circumstances:
• Under Windows, VNC Server in User Mode stops automatically when the last user disconnects if the
When last VNC Viewer disconnects option is changed to Logoff user. For more information, see
Protecting the host computer on page 119.
• A connected user can explicitly stop VNC Server if they know the credentials of an administrative user.
• A connected user can log off and/or power down the host computer.
To see how to start VNC Server again, read Starting VNC Server on page 73.
