Embodiment Construction

[0029] In order to make the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Please refer to figure 1 , the virtual machine online screen recording system in the cloud computing environment based on VNC proxy includes three parts, namely the VNC client (vncapplet client) implemented by java applet that can be embedded in the browser, VNC remote access and screen recording proxy server (VNC proxy server) and a VNC server installed on a virtual machine.

[0031] The VNC client of the Java applet is mainly used to display the desktop of the virtual machine. It implements the VNC-based RFB remote access protocol, which can capture the user's input of mouse and keyboard messages to the virtual machine, and display the updated data of the virtual machine desktop on the on the applet client (vnc applet client).

[0032] The VNC proxy server is mainly used to receive the virtual machine remote...

Abstract

The invention discloses a virtual machine online screen record method in cloud computing environment based on VNC agent and a virtual machine online screen record system thereof. The online screen record system comprises a VNC client side, a VNC proxy server and a VNC server which is installed on a virtual machine. The virtual machine is accessed by a browser client side. The VNC proxy server receives a virtual machine access request from a browser. The VNC proxy server initializes virtual machine access information and forwards authentication information brought by the client side to the VNC server. The VNC server performs security authentication of the access. Meanwhile, the VNC proxy server starts a screen record thread to perform screen recording of the interface of the virtual machine and generates a screen record file to be saved in the VNC proxy server. With application of the method and the system, operation of auditing and evidence collecting users on the virtual machine can be further standardized, and a virtualized application or system online screen record function based on cloud computing can be realized.

Description

technical field [0001] The invention relates to an online monitoring and screen recording technology for remote access of a virtual machine, in particular to a method and system for online access and screen recording of a virtual machine based on a cloud computing environment. Background technique [0002] With the rapid development of Internet technology and cloud computing, the use of virtual machines is becoming more and more common, but the development of technology has also brought more and more security issues. In order to further standardize the audit and evidence collection of users' operations on virtual machines, A virtualized application or system based on cloud computing needs to provide an online screen recording function. For example, in the network attack and defense drill platform, in order to be able to monitor all the operations of the user during the drill, it is necessary to record and replay the whole drill in real time. But there is no need to record a...
