Method of VNC (virtual network computer) protocol remote desktop

The invention relates to the technical field of cloud computation, in particular a method of VNC (virtual network computer) protocol remote desktop. The method comprises the following steps: firstly installing a VNC Server on a host computer so as to provide the remote desktop service; and then running a Flash security strategy file on the host computer to monitor 843 port; a WEB page requesting the address of the VNC server and the port of the VNC desktop to a WEB server, and checking whether the server 843 port has the security strategy file according to the VNC server address after the response; if the 843 port does not request the strategy file or is disallowed to connect, disconnecting and throwing the security error; if the 843 port returns the strategy file, sending a command of connecting a VNC protocol, and receiving the protocol data from the VNC server. Through the adoption of the Flash technology, the non-IE kernel and the IE kernel browser can be compatible with each other; the operation experience is improved, and the original dual-mouse disadvantage of the VNC client is solved.
