Description

Technical Field

[0001] The present application relates to the technical field of cloud computer services, and more specifically, to a network modification method, system, device, and computer-readable storage medium. Background Art

[0002] Currently, in scenarios such as Internet cafes, the technical solutions of cloud diskless and cloud computers are adopted, that is, there is no physical hard disk as the C drive to act as the boot disk, but a network hard disk is used as the boot disk. The problem brought about by this is that the boot speed of diskless may be slower than that of an SSD disk. In a cloud computer environment, the waiting time for users may even be as long as 40 seconds to more than 90 seconds. This is very poor for the user experience. Therefore, a solution is needed to allow users to quickly connect to the cloud computer and enjoy cloud services as soon as possible.

[0003] Based on this, a pre-boot solution is proposed, that is, when the user has not requested the cloud computer environment, multiple cloud computers are pre-opened and paused at a certain stage. There are no application programs or task business programs at this stage, ensuring the cleanliness of the user environment. When the user issues a resource scheduling request, the network such as the IP, gateway, and subnet mask is modified to achieve network connectivity with the user. At the same time, this computer is designated as the IP corresponding to the specified computer number in the specified Internet cafe. Then, after network connectivity, the resource package corresponding to the user's request is sent, such as: game resource package, office resource package, etc. During this process, there is a problem: when the user has not issued a cloud computer request, only the driver is running during the diskless pause stage, and no application programs are running. Then, when a user's resource scheduling request arrives, in order to achieve network connectivity with the user and divide the resources to the specific computer number of the specific Internet cafe, a function is required - to be able to modify the IP, gateway, and subnet mask during the driver stage. However, currently, the technologies for modifying the IP, gateway, and subnet mask all need to be implemented at the application layer after entering the desktop, and there is no open-source solution that can modify the IP, gateway, and subnet mask when the application layer has not been started during the driver stage.

[0050] Please refer to Figure 1 , Figure 1 It is the first flowchart of a network modification method provided by an embodiment of the present application.

[0051] A network modification method provided by an embodiment of the present application may include the following steps:

[0052] Step S101: Obtain the modified target network information.

[0053] In practical applications, the modified target network information can be obtained first, that is, the network information of the target cloud computer set by the user or the like. The type, content, etc. of the target network information can be determined according to actual needs, and the present application does not make specific limitations here.

[0054] Step S102: At the driver stage of the target cloud computer, open the symbolic connection of the NSI device of the target cloud computer based on ZwCreateFile.

[0055] In practical applications, after obtaining the modified target network information, at the driver stage of the target cloud computer, the symbolic connection of the NSI (Network Service Interface) device of the target cloud computer can be opened based on ZwCreateFile, so as to establish a communication connection with the NSI device of the target cloud computer and prepare for modifying the network information of the target cloud computer based on the target network information.

[0056] Step S103: Construct a target structure based on the target network information according to a preset data structure.

[0057] In practical applications, during the driver stage of the target cloud computer, after opening the symbolic link of the NSI device of the target cloud computer based on ZwCreateFile, a target structure can be constructed based on the target network information according to a preset data structure, so as to encapsulate the target network information with the target structure and prepare for subsequent transmission of the target network information to the target cloud computer.

[0074] It may include: actionType parameter, subType parameter, subTypeDo parameter, actionArgs parameter, actionArgsEx1 parameter; among them, the actionType parameter is used to characterize the type of network information; the subType parameter and subTypeDo parameter are used to characterize the modification type of network information; the actionArgs parameter and actionArgsEx1 parameter are used to point to pointer memory, and the pointer memory is used to save the target network information; correspondingly, in the process of calling the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer, 0x1200013 can be used as the IoControlCode to call the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer.

[0075] It should be noted that in the process of constructing the target structure based on the target network information according to the preset data structure, not all parameters in the data structure will be applied. At this time, the values of the unused parameters can be set to null, etc., to indicate that the corresponding parameters are not transmitted, etc. This application does not make specific limitations here. In addition, after calling the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer, if the target cloud computer returns a corresponding value, and the return value indicates that the target cloud computer responds correctly to the target structure, it can be determined that the network information of the target cloud computer is successfully modified, etc. This application does not make specific limitations here.

[0076] A network modification method provided by the present application obtains the modified target network information; in the driver stage of the target cloud computer, based on ZwCreateFile, it opens the symbolic link of the NSI device of the target cloud computer; according to a preset data structure, it constructs a target structure based on the target network information; calls the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer to modify the network of the target cloud computer based on the target structure. In the present application, in the driver stage of the target cloud computer, the symbolic link of the NSI device of the target cloud computer can be opened based on ZwCreateFile to prepare for modifying the network of the target cloud computer later; and then, according to a preset data structure, a target structure can be constructed based on the target network information, and the ZwDeviceIoControlFile function can be called to transfer the target structure to the target cloud computer to modify the network of the target cloud computer based on the target structure; it realizes modifying the network information of the target cloud computer in the driver stage by means of ZwCreateFile and ZwDeviceIoControlFile. In addition, because the used ZwCreateFile and ZwDeviceIoControlFile are standard functions in the computer, the compatibility of the present application is good and it will not cause abnormalities such as blue screens, ensuring the user experience.

[0077] Please refer to Figure 2 , Figure 2 which is the second flowchart of a network modification method provided by an embodiment of the present application.

[0078] A network modification method provided by an embodiment of the present application may include the following steps:

[0081] Step S203: According to a preset data structure, construct a first target structure based on the network information; among them, the value of the actionType parameter in the first target structure is a preset value used to represent the IP; the values of the subType parameter and the subTypeDo parameter are preset values used to represent the operation of issuing the target IP and the target subnet mask; the pointer memory pointed to by the actionArgs parameter is used to store the target IP address; the pointer memory pointed to by the actionArgsEx1 parameter is used to store the target subnet mask information.

[0082] In practical applications, the target network information may include the target IP address and the target subnet mask information. At this time, in the process of constructing the target structure based on the target network information according to the preset data structure, the first target structure can be constructed based on the network information according to the preset data structure. Among them, the value of the actionType parameter in the first target structure is the preset value used to represent the IP, such as 0xA; the values of the subType parameter and the subTypeDo parameter are the preset values used to represent the operation of sending down the target IP and the target subnet mask, such as the subType parameter is set to 0x1 and the subTypeDo parameter is set to 2; the pointer memory pointed to by the actionArgs parameter is used to store the target IP address; the pointer memory pointed to by the actionArgsEx1 parameter is used to store the target subnet mask information.

[0083] Step S204: Call the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer to modify the network of the target cloud computer based on the target structure.

[0084] In a specific application scenario, in order to ensure that the target IP address and the target subnet mask information can be successfully set and to ensure compatibility, before constructing the first target structure based on the target network information according to the preset data structure, the original IP address of the target cloud computer can also be activated, that is, the first original structure needs to be constructed based on the original IP address according to the preset data structure. Among them, the value of the actionType parameter in the first original structure is the preset value used to represent the IP, such as set to 0xA; the values of the subType parameter and the subTypeDo parameter are the preset values used to represent the operation of sending down the original IP, such as the subType parameter is set to 0x3 and the subTypeDo parameter is set to 1; the pointer memory pointed to by the actionArgs parameter is used to store the original IP address; call the ZwDeviceIoControlFile function to transfer the first original structure to the target cloud computer to activate the original IP address of the target cloud computer.

[0085] In a specific application scenario, in order to avoid conflicts between the original IP address and the target IP address, after activating the original IP address of the target cloud computer and before constructing the first target structure based on the preset data structure for the target network information, it is also necessary to release the original IP address of the target cloud computer, that is, the original IP address of the target cloud computer can be obtained; based on the original IP address, a second original structure is constructed according to the preset data structure; among them, the value of the actionType parameter in the second original structure is a preset value used to represent the IP, for example, set to 0xA; the values of the subType parameter and the subTypeDo parameter are preset values used to represent the operation of releasing the original IP, for example, the subType parameter is set to 0x3 and the subTypeDo parameter is set to 0; the pointer memory pointed to by the actionArgs parameter is used to store the original IP address; and the ZwDeviceIoControlFile function is called to transmit the second original structure to the target cloud computer to release the original IP address of the target cloud computer.

[0086] Please refer to Figure 3 , Figure 3 which is the third flowchart of a network modification method provided by an embodiment of the present application.

[0089] Step S302: In the driver stage of the target cloud computer, open the symbolic link of the NSI device of the target cloud computer based on ZwCreateFile.

[0090] Step S303: Based on the network information, construct a second target structure according to the preset data structure; among them, the value of the actionType parameter in the second target structure is a preset value used to represent the gateway; the values of the subType parameter and the subTypeDo parameter are preset values used to represent the operation of issuing the target gateway; the pointer memory pointed to by the actionArgs parameter is used to store the target gateway information.

[0091] In practical applications, the target network information may include target gateway information; correspondingly, in the process of constructing a target structure based on the target network information according to a preset data structure, a second target structure may be constructed based on the network information according to the preset data structure; wherein, the value of the actionType parameter in the second target structure is a preset value used to represent a gateway, such as set to 0x10; the values of the subType parameter and the subTypeDo parameter are preset values used to represent the operation of sending down the target gateway, such as the subType parameter is set to 0x3 and the subTypeDo parameter is set to 0; the pointer memory pointed to by the actionArgs parameter is used to store the target gateway information. In addition, the actionArgsEx1 parameter can also be used to store the corresponding information of the target gateway information, such as the storage location of the target gateway information in the memory, that is, the memory of 32 bytes of 0xFF can be pointed to the actionArgsEx1 parameter, etc.

[0092] Step S304: Call the ZwDeviceIoControlFile function to transfer the target structure to the target cloud computer to modify the network of the target cloud computer based on the target structure.

[0093] In a specific application scenario, in order to ensure the compatibility and security of the target gateway information, before constructing the second target structure based on the target network information according to the preset data structure, it is also necessary to release the original gateway of the target cloud computer, that is, it is necessary to obtain the original gateway of the target cloud computer; construct a third original structure based on the original IP address according to the preset data structure; wherein, the value of the actionType parameter in the third original structure is a preset value used to represent a gateway, such as set to 0x10; the values of the subType parameter and the subTypeDo parameter are preset values used to represent the operation of releasing the original gateway, such as the subType parameter is 0x3 for us and the subTypeDo parameter is set to 1; the pointer memory pointed to by the actionArgs parameter is used to store the original gateway; finally, call the ZwDeviceIoControlFile function to transfer the third original structure to the target cloud computer to release the original gateway of the target cloud computer.
