Restricting functionality for connected users

By default, any number of users can connect to an instance of VNC Server running on a host computer. Each user can:

•  Control the host computer using their client computer’s keyboard and mouse, for example running applications, changing settings, and accessing data (according to their privileges on the host computer).

•  Copy and paste text between applications running on the client and host computers.

In addition, for connections to VNC Server (Enterprise) and VNC Server (Personal), users can:

•  Print host computer files to a printer attached to the client computer.

•  Exchange files with the host computer.

•  Chat with other VNC Viewer users connected to the same host computer, or with a host computer user.

You can restrict access to RealVNC™ remote control features for all connected users, if necessary, by configuring options on the Inputs tab of the VNC Server - Options dialog. More on this dialog.

Note: In some circumstances, you can restrict access to features for particular users by revoking VNC permissions. See Restricting features for particular connected users for more information.

Making VNC Server ‘view only’

You can quickly prevent all interchange with all client computers, making the host computer ‘view only’. This might be useful in an educational environment, for example, when multiple users are connected but must not interact. To do this, select Disabled (view-only mode) from the Inputs dropdown.

Disabling the keyboards of client computers

You can disable the keyboards of all client computers. To do this, turn off Enable keyboard input.

Disabling the mice of client computers

You can disable the mice of all client computers. To do this, turn off Enable mouse input.

Preventing printing

For VNC Server (Enterprise) and VNC Server (Personal), you can prevent all connected users printing host computer files to local printers. To do this, turn off Allow VNC Viewers to share printers. Note this option is on the Printing tab. For more information about this feature, see Printing host computer files to a local printer.

Under UNIX/Linux, if you have root privileges on the host computer, you can disable printing system-wide. To do this, run the command vncinitconfig -disable-print in a Terminal window, and press the ENTER key. The Printing tab is disabled. To reverse this, run the command vncinitconfig -enable-print.

Under Windows, if you have sufficient privileges on the host computer, you can disable printing system-wide by re-installing VNC Server without the VNC Printer Driver component. To do this, turn off VNC Printer Driver at the appropriate step in the Installation Wizard. For more information on installation, visit www.realvnc.com/products/vnc/documentation/5.0/installing-removing/windows. The Printing tab is disabled.

Preventing file transfer

For VNC Server (Enterprise) and VNC Server (Personal), you can prevent all connected users exchanging files with the host computer. To do this, turn off Share files with VNC Viewers. For more information about this feature, see Transfering files between client and host computers.

Preventing copy and paste text

You can prevent all connected users copying and pasting text between applications running on the client and host computers. To do this, turn off Share clipboard with VNC Viewers. For more information about this feature, see Copying and pasting text between client and host computers

Note: Under Windows, note that files can be copied and pasted by connected users to client computers also running Windows. To prevent this, turn off Share files with VNC Viewers.

Preventing chat

For VNC Server (Enterprise) and VNC Server (Personal), you can prevent connected users communicating securely using chat. To do this, turn off Enable chat. For more information about this feature, see Communicating securely using chat.
