Extended knowledge
VNC (Virtual Network Console) is the abbreviation of virtual network console. It is an excellent remote control tool software developed by the famous AT&T European Research Laboratory. VNC is a free open source software based on UNIX and Linux operating systems. It has powerful remote control capabilities, is efficient and practical, and its performance is comparable to any remote control software in Windows and MAC. In Linux, VNC includes the following four commands: vncserver, vncviewer, vncpasswd, and vncconnect. In most cases users only need two of these commands: vncserver and vncviewer.
VNC is basically composed of two parts: one is the client application (vncviewer); the other is the server-side application (vncserver). The basic operating principle of VNC is very similar to some remote control software under Windows. The server-side application of VNC is highly adaptable in UNIX and Linux operating systems, and the graphical user interface is very friendly and looks very similar to the software interface under Windows. Any Linux platform computer with the client application (vncviewer) installed can easily connect to a computer with the server application (vncserver) installed. In addition, the server side (vncserver) also has a built-in Java Web interface, so that users' operations on other computers through the server side can be displayed through Netscape. This operation process and display method are more intuitive and convenient.
