Principles of VNC remote control

To connect to and control one computer from another:

•  An application called VNC Server must be running on the host computer; that is, on the computer you want to control. To obtain the latest version of VNC Server, download VNC from www.realvnc.com/download/vnc/. Follow the instructions to license it, or consult Licensing VNC Server.

Note: You may be able to control computers running alternatives to VNC Server. For more information, see Connecting to VNC-compatible Server applications.

•  An application called VNC Viewer must be running on the client computer; that is, on the computer you are sitting in front of, and want to exercise control from. The latest version of VNC Viewer is available to download from www.realvnc.com/download/viewer/.

Note: You may be able to control computers using alternatives to VNC Viewer. For more information, see Connecting from alternatives to VNC Viewer.

•  Host and client computers must be connected to the same TCP/IP network. This can be a private network such as a LAN or VPN, or a public network such as the Internet. Note that firewalls and routers must typically be configured before an Internet connection can be established. See Connecting over the Internet for more information.

For information on how to set these applications up, see Getting the computers ready to use.

Consider the following example environment:

A.  Client computer (typically a laptop or desktop) running VNC Viewer.   B.  Client device (handset or tablet) running VNC Viewer for iOS or Android.   C.  Host computer (typically a workstation or server) running VNC Server.   D.  Router exposing a public network address for Internet connections to the host computer.

To start a remote control session, run VNC Viewer and identify VNC Server on the host computer you want to control. Once authenticated, VNC Viewer displays the host computer’s desktop in a new window, and you can take control using the client computer’s keyboard and mouse. You can run applications, change settings, and access data on the host computer exactly as you would be permitted to do were you sitting in front of it. See a picture.

Note: By default, VNC Server permits other users to connect to the host computer at the same time as you. You may be sharing control.

VNC remote access and control software solves different problems for users with different requirements, from the family member troubleshooting computer problems over the Internet to the system administrator configuring devices remotely in an enterprise environment.
