How to Watch a Client Computer From a Server

The Virtual Network Computing (VNC) protocol is a graphical sharing desktop system that uses the RFB protocol in order to control another computer remotely. Because the VNC is platform-independent, a viewer on one operating system can connect to a VNC server on any other operating system in addition to the same server. Also, multiple clients can connect to a VNC server simultaneously. This technology is popular for remote technical support operations that access files on work, home and off-site client computers. VNC was developed at the Olivetti Research Laboratory in Cambridge, United Kingdom. The source code and derivatives are open source under the GNU General Public License.

Instructions

1. Step 1

   Determine which variant of VNC to use. Some are optimized for Microsoft Windows, or offer file transfer, which is not a part of VNC proper. Most can be compatible without added features, while others can be based upon VNC code, yet not be compatible with the standard VNC application.

2. Step 2

   Obtain VNC protocol software that will allow for the control of the computer from any server location. To install the VNC server, use a solution such as TightVNC for Windows systems. TightVNC allows for file transfers for slow connections and high compression levels. Download TightVNC to run on the home server or computer. After starting the server, set an incoming connection password. For Mac systems, try the OSXvnc free VNC server. Download the software, install it and set up a server password. Put a VNC viewer on a USB memory stick so that you don't have to download and install it on every computer you may want to connect to the main computer or server. Alternatively, you can use the LogMeIn web-based application instead of TightVNC.

3. Step 3

   Visit WhatIsMyIP from the home or main server computer to determine its IP address and write down the IP address password if connected directly to the Internet.

4. Step 4

   Download and install TightVNC on the remote VNC client. Start the viewer rather than the server. On Macs, download free Chicken of the VNC Mac viewer for connection to the home or main server PC. Enter the IP address and password for connection.

5. Step 5

   Open a port on the router's firewall and forward requests to the main computer or server, if it is behind a network firewall. Alternatively, you may enter the main computer or server's domain name.
