5.3.1 What is VNC?
Posted by Evita Lin on 18 February 2017 04:48 PM

Virtual Network Computing (VNC) is a remotely control system that uses the Remote Frame Buffer protocol (RFB) to another computer.

It is an open source software developed by Cambridge University AT&T lab.


Browser with Java-enabled can use, do not need to install the VNC Viewer.

Log in to the host computer, the other user can still be used normally without log out.

VNC can not transfer any file.

Because VNC transfer "graphics" over the network, it takes more bandwidth.

Switching input method is more inconvenient; mainly involves the rapid key combination of transmission problems.


If VNC can not be connected, please check:


  • Does Java7 be installed ?
  • Does the host Turn off its firewall ?
  • Make sure that VNC SERVER has turned on.


Get into the Control Panel interface and click on the VNC function, it will show the screen.

Control Panel: http: //

Win7 or Win10 is recommended to choose "HTML5 VNC Client SSL"

And remember to allow bouncing windows. (IE / Firefox / Chrome)


The "Java VNC Client" requires Java version 7 or under version 7.

Please adjust the security to the intermediate level.

Java version 8 will be blocked due to the security problem.

Chrome does not support Java.
