Method and system for sharing clipboard by virtual machine between independent networks of network range

Abstract

The invention discloses a method and a system for sharing a clipboard by a virtual machine between independent networks of a network range. The method mainly comprises the steps of synchronous code configuration, clipboard content export and import. The method comprises the following steps: firstly, configuring and storing a synchronous code on a virtual machine, wherein the virtual machines configured with the same synchronous code can share a clipboard; the method comprises the following steps: monitoring a copy event on a virtual machine to mark whether a clipboard has content needing to be sent out or not; when outgoing is needed, outgoing content is sent to a server where the virtual machine is located through serial port equipment on the virtual machine, and the outgoing content is stored in a shared database and / or a shared file system connected with the server; and when the clipboard content is imported, acquiring the synchronous code configured on the virtual machine through the serial port equipment, querying the stored latest clipboard content according to the synchronous code, transmitting the latest clipboard content to the virtual machine through the serial port equipment, and writing the latest clipboard content into the system clipboard. Nodes in a scene can communicate with a network directly, and the application range of a clipboard sharing program is widened.

Description

technical field [0001] The invention relates to a clipboard sharing method and system for virtual machines among independent networks of a network shooting range, and belongs to the field of virtual network platforms and computer software. Background technique [0002] In the network shooting range environment, each user will maintain multiple target machine nodes at the same time. These target machine nodes may be distributed anywhere in the topology of the shooting range scene. The network between target machine nodes may not be able to communicate. The target machines copy text, pictures, files, folders, etc. to each other for security protection or network attack training, so it is necessary to use the clipboard sharing program to complete the operation of copying and pasting between different target machines. [0003] Such as figure 1 As shown, the existing clipboard sharing method is based on the network. The user needs to first install the clipboard sharing program o...

AI Technical Summary

Problems solved by technology

The limitation of the existing clipboard sharing scheme is that the network between different machines needs to be connected, and it is not suitable for sharing the clipboard with the independent network of the network range
