A Media Access Control (Media Access Control, MAC) address is an identifier for identifying a local area network (Local Area Network, LAN) node. MAC address is also known as physical address. For example, the size of the physical address is 48 bits, the first 24 bits are the serial number of the manufacturer, and the last 24 bits are the serial number of the network card.

(2), network card

A network card is a piece of computer hardware designed to allow a computer to communicate over a computer network. Because it has a MAC address, it belongs between the first and second layers of the Open System Interconnection Reference Model (English: Open System Interconnection Reference Model, abbreviated as OSI). It allows users to connect to each other via cable or wirelessly.

(3), main board

Motherboard, also known as Mainboard, System Board, or Motherboard, is one of the most basic and important components of a computer. The motherboard plays a pivotal role in the entire computer system. The quality of motherboard manufacturing determines the stability of the hardware system. The motherboard is the core of the computer hardware system, and it is also the largest printed circuit board in the main box. The main function of the motherboard is to transmit various electronic signals, and some chips are also responsible for preliminary processing of some peripheral data. All components in the host computer are connected through the motherboard, and the control of system memory, storage devices and other input/output (I/O) devices must be completed through the motherboard during normal operation of the computer. Whether the performance of the computer can be fully utilized, whether the hardware functions are sufficient, and how compatible the hardware is, all depend on the design of the motherboard.

(4), computer equipment

Computer equipment in this article refers to equipment including network cards and motherboards, such as servers, computers (desktop computers, notebook computers, etc.), single-chip microcomputers, and other equipment with network access. Wherein, the MAC address of the computer device is the MAC address of the network card.

The above description of technical terms can be applied in the following.

The embodiment of the present application provides a device control method, which can remotely control a computer device to execute a target operation, and the implementation cost is low.

The equipment control method provided by this application is described in detail below:

The device control method in the embodiment of the present application is applied to a control system. The above control system includes a control device and at least one computer device. Hereinafter, the device control method will be described in detail by taking one of the at least one computer device as an example.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a device control method provided in an embodiment of the present application. The above-mentioned device control method includes the following steps:

201. The computer device receives the operation message broadcast by the control device. The operation message includes an operation message header, a target physical address of the target computer device, and target verification information of the target computer device.

For example, the control device is connected to multiple computer devices, and the control device broadcasts operation messages to the multiple computer devices.

Specifically, the operation message is a LAN message, that is, a Layer 2 network protocol message, and the length of the LAN message is not limited. Wherein, the target verification information is the use license authorization information of the target computer device, for example, the target verification information includes the target password.

202. When the operation message meets the preset conditions, the target physical address is the same as the local physical address of the computer device, and the target verification information is consistent with the local verification information of the computer device, the computer device executes the target operation, and the target operation is performed After completion, the computer device determines that the operation result of the operation message is a successful operation. Wherein, the preset condition includes that the number of repetitions of the target physical address in the operation message is greater than or equal to the preset number, and/or, the length of the header of the operation message is greater than or equal to the preset length.

Among them, whether the operation message satisfies the preset conditions, whether the target physical address is the same as the local physical address of the computer device, and whether the target verification information is consistent with the local verification information of the computer device, and there is no special limitation on the judgment order of the above three .

Specifically, by setting the number of repetitions of the target physical address and/or the length of the operation message header to distinguish it from other messages, when the computer device parses the number of repetitions of the physical address contained in the received operation message is greater than or equal to When the preset number of times and/or the length of the operation message header is greater than or equal to the preset length, it is confirmed that the operation message is a message for controlling the target computer device to perform the target operation.

Wherein, the specific value of the preset number of times can be set according to the actual situation, so that the operation message can be distinguished from other messages. For example, the preset times are 5, 10 or 16 and so on. As a further example, the number of repetitions of the target physical address in the operation message is smaller than the number of repetitions of the physical address in the service message.

Similarly, the specific value of the preset length can be set according to the actual situation, so that the operation message can be distinguished from other messages. For example, the preset length is 5 bytes, 6 bytes or 10 bytes, etc. In a further example, the length of the header of the operation message is smaller than the length of the header of the service message.

Exemplarily, the local verification information of the computer device includes a local password, and the local password may be a password set by the user of the computer device (when the password verification is passed, the user can use the computer device), or the local password is an omnipotent password, That is, the use password applicable to at least one computer device in the control system.

203. The computer device sends the operation result of the operation message to the control device.

Correspondingly, the control device receives the operation result of the operation message from the computer device.

Specifically, the manner in which the computer device sends the operation result of the operation message to the control device may be to send a result message to the control device, and the specific structure and message length of the result message are not particularly limited. Exemplarily, the information contained in the result message includes the operation result of the operation message, for example, "1" indicates that the operation is successful, and "0" indicates that the operation fails. Exemplarily, the information included in the result message further includes at least one of the following: local physical address information of the computer device, or result message indication information, and the like. For example, the indication information of the result message is "AAAA" of 2 bytes or "BBBBBBBB" of 4 bytes. Among them, A and B are hexadecimal numbers.

In the embodiment of the present application, the control device can remotely control the computer device to perform the target operation through the operation message (understood as a local area network data packet), and does not depend on whether the computer device is installed with a remote access control system (such as a BMC system), and the realization cost Low.

As a possible implementation manner, the above operation message further includes operation instruction information, and the operation instruction information is used to instruct the target computer device to perform the target operation; at this time, the preset condition is that the operation message includes the operation instruction information.

Exemplarily, when the target operation is a power-off operation, the operation indication information is "DDDD" of 2 bytes. In another example, when the target operation is a restart operation, the operation indication information is "CCCC" of 2 bytes. Among them, C and D are hexadecimal numbers.

In the embodiment of the present application, when the operation message includes the above operation indication information, it can be determined that the operation message is used to control the target computer device to perform the target operation. Of course, when the operation message includes the operation message header, target physical address, target verification information and operation instruction information, the preset condition can still be that the number of repetitions of the target physical address in the operation message is greater than or equal to the preset number of times, and/or Or, the length of the operation header is greater than or equal to the preset length.

As a possible implementation manner, the foregoing target operation includes powering off, restarting, or powering on after waiting for a first time after powering off.

Wherein, power off refers to safe power off, and safe power off can be understood as computer equipment controlling the internal parts of the equipment to stop working according to a certain power off order to realize shutdown, or computer equipment performs data synchronization before power off to avoid computer equipment failure. The system data is corrupted, resulting in a failure when the power is turned on again. The above-mentioned power-off sequence can be determined according to the actual situation of the computer equipment.

Reboot means power on immediately after power off. The target operation can also be to wait for a period of time after power off and then power on, such as waiting for the first time before powering on, the specific value of the first time can be set according to the actual situation.

As a possible implementation manner, the target verification information further includes at least one of the following: a target user name of the target computer device, and a physical address of the control device. Correspondingly, the local verification information further includes at least one of the following: a local user name of the computer device, and a physical address of the control device.

Specifically, verifying the user name can assist in verifying the authenticity of the controlling device. When the target user name is the same as the local user name of the computer device, it indicates that the control device broadcasting the operation message is a trusted device. Likewise, verifying the physical address of the control device can confirm whether the operation message is broadcast by the control device. The computer device can obtain the physical address of the control device in advance, for example, the control device broadcasts its physical address to the computer device in advance or the user deposits it in advance. When the computer device determines that the physical address of the control device carried in the operation message is consistent with the physical address of the control device stored locally, it may determine that the operation message is broadcast by the control device.

As a possible implementation manner, the above device control method further includes:

When the target physical address in the operation message is different from the local physical address of the computer device, it can be determined that the operation message is not used to control the computer device, and the computer device can discard the operation message and not process the message.

Exemplarily, in order to save the data processing capacity of the computer equipment, it may first determine whether the target physical address is the same as the local physical address, then determine whether the target verification information is the same as the local verification information, and finally, determine whether the operation message satisfies the preset condition . In this way, when the physical address of the target or the verification information of the target fails to pass the verification, the subsequent judgment process can be stopped, saving the amount of data processing.

As a possible implementation manner, the above device control method further includes:

When the target physical address in the operation message is the same as the local physical address of the computer device, and the target verification information is inconsistent with the local verification information, the computer device sends a feedback message to the control device, and the feedback message is used to indicate the target verification information and the local verification information. The information is inconsistent, so that the control device knows that the target verification information is incorrect, and the control device can modify the target verification information and re-broadcast the operation message.

The specific structure of the feedback message is not particularly limited, as long as the control device can know that the target verification information is incorrect. Exemplarily, the feedback message may be "EEEEEEEEEEEEEEEE" of 8 bytes.

As a possible implementation manner, before the computer device receives the operation message broadcast by the control device, the device control method further includes:

The computer device receives the physical address request broadcast by the control device.

Accordingly, the control device broadcasts a physical address request.

Specifically, the foregoing physical address request may be a request based on various network protocols, such as Address Resolution Protocol (Address Resolution Protocol, ARP), Simple Network Management Protocol (Simple Network Management Protocol, SNMP), and the like.

ARP is a transmission control protocol (Transmission Control Protocol/Internet Protocol, TCP/IP) that obtains a physical address based on an IP address. Wherein, when the host sends information, it broadcasts the ARP request containing the target IP address to all hosts on the local area network, and receives the return message, so as to determine the physical address corresponding to the target IP address.

SNMP is a set of network management protocols defined by the Internet Engineering Task Force (IETF). Using SNMP, a management workstation (ie, the control device in this embodiment of the application) can remotely manage all network devices that support this protocol (ie, the computer equipment in this embodiment of the application).

The computer device sends the local physical address to the control device in response to the physical address request.

Correspondingly, the control device receives the local physical address sent by the computer device in response to the physical address request.

In the embodiment of the present application, before the control device remotely operates the computer device, it needs to obtain the local physical address of the computer device through a physical address request. When the computer device needs to be operated, the local physical address of the computer device is used as the target physical address.

As a possible implementation, for local verification information (such as local password and local user name), it can be collected and entered into the control device in advance, so that the control device according to the collected local verification information and the local physical address of the computer device, The computer device can be remotely operated as required, specifically, when the computer device needs to be operated, the local verification information of the computer device is used as the target verification information.

As a possible implementation manner, refer to FIG. 3 , which is a schematic structural diagram of an operation message provided in an embodiment of the present application. In this embodiment, the length of the operation message is 108 bytes as an example, and the target operation is power-off operation, the target verification information is the password set by the user, the preset number of times is 16, and the preset length is 6 bytes. Specifically, the structure of the operation message starts with a 6-byte operation message header (such as FF FF FF FF FF FF FE), followed by the 48-bit (6-byte) MAC address of the target computer device repeated 16 times, The last is a 6-byte password, a total of 108 bytes.

As a possible implementation manner, refer to FIG. 4 , which is a schematic structural diagram of a result message provided in an embodiment of the present application. In this embodiment, the length of the result message is 108 bytes as an example, and the target operation is a power-off operation. The message structure starts with a 6-byte result message header (such as FF FF FF FF FF FF FD); followed by a 48-bit MAC address repeated 16 times; followed by a 1-byte operation result, for example, You can use 1 to indicate power-off success, and 0 to indicate power-off failure; the last 5 bytes are reserved bytes for subsequent use for other purposes. Among them, the structure of the result message is consistent with that of the operation message, which is for the convenience of software development and operation and maintenance. As a result, the MAC address in the message does not need to be repeated 16 times, and only one MAC address is used as the identification of the computer device.

Furthermore, the target operation takes the power-down operation as an example. First, the control device obtains the MAC addresses of all servers in the LAN by broadcasting ARP packets, and stores the passwords of each server in the control device in advance. Then, when it is necessary to remotely power off the server, the operation message is broadcast again, and the operation message carries the MAC address of the server that you want to control the power off. You can also broadcast the operation message multiple times to realize batch Power off all servers in the control lab.

Taking the power off of the control server 3 as an example, the control device assembles a message containing the MAC address and password information of the server 3 and sends it over the LAN. When the server 3 receives the operation packet containing the local MAC address, the operation packet satisfies the preset conditions, and the password verification passes, the power-off process is performed. The server 3 is waiting for the completion of the power-off process, and sends the power-off operation result including the local MAC address to the control device. The control device receives and records the result of the power-off operation, and the control process ends.
