Installation and Use of VNC

1. Introduction to VNC

 VNC is short for a virtual network computer. It is a remote control tool that remotely connects to Linux and UNIX in windows. VNC is a free open-source software based on UNIX and Linux operating systems, with powerful remote control capabilities.

VNC consists of two parts: the client application (vncviewer) and the server application (vncserver ). The basic operating principle of VNC is similar to some remote control software in windows. VNC server applications are highly adaptable in UNIX and Linux, and the graphic user interface is very friendly. It looks similar to the software interface in windows. On any Linux platform computer that has installed the client application (vncviewer), it is very convenient to connect to the computer that has installed the server application (vncserver.

In addition, the server (vncserver) also has a built-in Java Web interface, so that the user's operations on other computers can be displayed through Netscape, this operation process and display method are more intuitive and convenient.

 

2. Install VNC

Before installation, check whether the disc is connected.
