Embodiment Construction

[0023] As shown in the figure, the method of the present invention includes the following steps:

[0024] 1. Install VNC Server on the host computer to provide remote desktop services;

[0025] 2. Run the Flash security policy file on the host machine and monitor port 843;

[0026]

[0027] 3. The WEB page requests the address of the VNC server and the port of the VNC desktop from the WEB server; Step 4: After the response, check whether there is a security policy file on port 843 of the server according to the address of the VNC server;

[0028]

[0029]

[0030] 4. Port 843 does not request a policy file or is not allowed to connect, go to step 6, otherwise go to step 7;

[0031] 5. A security error is thrown when the connection is disconnected;

[0032] securityErrorHandler information: [SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error#2048"]

[0033] 6. Send the command to connect to the VNC protocol, and receive t...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a VNC protocol remote desktop method. Background technique [0002] VNC (Virtual Network Computer) is the abbreviation of virtual network computer. 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, high efficiency and practicality, and its performance can be comparable to any remote control software in Windows and MAC. Currently, the HTML5 method is used to access the VNC protocol remote desktop from the WEB page. This mechanism has problems in user experience, and different solutions need to be designed for different browsers to improve user experience, and currently not all browsers support HTML5. Contents of the invention [0003] The technical problem solved by the present invention is ...
