Description

Configuration change method and device and electronic equipment

Technical Field

The invention relates to the technical field of network security audit, in particular to a configuration change method and device and electronic equipment.

Background

With the rapid development of IT technology, more and more services are loaded on an IT network, the network has larger and larger scale, more and more complex structure and higher and more complex configuration of equipment, and higher requirements are put forward for network administrators. The centralized management platform is centralized with a large number of devices, and the terminal devices need to know the address and other information of the centralized management platform to perform normal communication. The server supports configuration of multilink, and changes information such as an IP address of a platform which is centrally managed. Due to the complexity of the existing network configuration, the terminal device and the server may span different networks, and the server cannot obtain the real IP address of the terminal device or directly issue a configuration change message to the designated device. If the change information can not be notified to the terminal device, the normal service management operation of the whole system can be affected.

The scheme in the prior art is as follows: the management equipment sends a message to each member equipment in the member equipment group, and indicates the member equipment in the member equipment group to reserve basic configuration items when configuration change is carried out by utilizing the configuration file corresponding to the equipment group. When it is monitored that the configuration file corresponding to the member device group conforms to the trigger configuration change, each device member in the device group performs configuration change by using the corresponding configuration file, and updates the other configuration items except the basic configuration item. The basic configuration items comprise working modes, communication protocols used between the management equipment and the member equipment and IP addresses used in communication.

In the prior art, the information change of the management server to the terminal equipment is limited to non-basic information, and the IP address of the server cannot be modified. The existing network server generally supports the configuration of multiple links, and if the IP address of a certain link of the management server is changed, the current scheme cannot realize the change management, so that the management server and the terminal device cannot communicate.

In summary, in the prior art, a method for automatically updating link configuration information by a terminal device when IP addresses of multiple communication links of a server are changed is absent.

Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion. Further, in the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specified.

The overall concept of the embodiment of the invention is as follows: when the multilink configuration information of the server needs to be changed, a broadcast message is sent to the managed equipment to inform the configuration information to be changed, and then at least one of the server IP address, the server monitoring port, the server response port and the pre-shared key of the communication link of the server is automatically changed within preset time.

The application provides a configuration change method which can be applied to an application environment shown in FIG. 1. FIG. 1 is a diagram of an application scenario of a configuration change method in one embodiment; the application environment includes at least one terminal device (3 terminal devices are illustrated in fig. 1 as an example, and the 3 terminal devices are aterminal device 11, aterminal device 12, and aterminal device 13, respectively) and aserver 14. Wherein the terminal device communicates with the server via a network. Specifically, the server sends a broadcast message to the terminal device to notify the changed configuration, wherein the broadcast message is realized based on the message communication framework already supported by the current system. The terminal equipment receives a configuration change instruction sent by the server; the configuration change instruction carries target configuration information corresponding to at least one communication link and is used for indicating the terminal equipment to change the original configuration information of the at least one communication link into the corresponding target configuration information; judging whether the at least one communication link comprises a target communication link, wherein the target communication link is a communication link used by the terminal equipment; and if so, updating the original configuration information of the target communication link into corresponding target configuration information. The terminal device may be, but not limited to, various smart phones, tablet computers, notebook computers, desktop computers, and portable wearable devices, and the server may be implemented by an independent server or a server cluster formed by a plurality of servers.

In one embodiment, as shown in FIG. 2, a configuration change method is provided. In this embodiment, the method is mainly applied to a terminal device for example, and includes the following steps:

s201, receiving a configuration change instruction sent by the server.

The configuration change instruction carries target configuration information corresponding to at least one communication link, and is used for indicating a terminal device using the at least one communication link to change original configuration information of the at least one communication link into corresponding target configuration information.

Illustratively, the terminal device may be a managed device. A server may have multiple IP addresses, each associated with a group of managed devices, each of which establishes a communication link with the server. For example, a first group of terminal devices is managed by a first IP address, and an nth group of terminal devices is managed by an nth IP address.

Specifically, the target configuration information is the configuration information after the modification of the corresponding item of the original configuration information. The managed device receives the configuration change instruction sent by the server.

S202, judging whether the at least one communication link comprises a target communication link. If the at least one communication link includes the target communication link, step S203 is executed.

Wherein the target communication link is a communication link used by the terminal device.

S203, updating the original configuration information of the target communication link into corresponding target configuration information.

As an optional implementation manner of the embodiment of the present invention, the implementation manner of step S203 may include:

and updating at least one of the server IP address, the server monitoring port, the server response port and the pre-shared key of the target communication link according to the target configuration information.

The IP Address is a unified Address format provided by the IP Protocol, and allocates a logical Address to each network and each host on the Internet, so as to shield the difference of physical addresses. For a device on a network, such as a computer or a router, whose IP address is designed based on the network topology, it is easy to change the IP address.

The server monitoring port is used for monitoring the client side by the server, is equivalent to an address, and is a link between the server and the client side. There are many services on a server, and port numbers distinguish different services on the server. After sending the request, the server transmits the request to different ports according to the port number for response.

In this embodiment, the pre-shared key functions as: the identities of the server and the managed device are confirmed.

As an optional implementation manner in this embodiment of the present invention, the configuration change instruction further carries original configuration information of the at least one communication link, and an implementation manner of the step S202 (determining whether the at least one communication link includes a target communication link) may include the following steps a and b:

a. and judging whether the server IP address of the original configuration information of the at least one communication link contains the server IP address of the target communication link.

b. And if so, determining that the target communication link is included in the at least one communication link.

Illustratively, the configuration change instruction further carries original configuration information of the at least one communication link, where the original configuration information includes a server IP address. The server IP address can be used as an identification method, and since the terminal device stores original configuration information, if the server IP address of the original configuration information of at least one communication link contains the server IP address of the target communication link, it can be determined that the target communication link is contained in the at least one communication link.

In one embodiment, the configuration change instruction further carries identification information of the at least one communication link;

the determining whether the at least one communication link includes a target communication link includes:

judging whether the identification information of the at least one communication link contains the identification information of the target communication link;

and if so, determining that the target communication link is included in the at least one communication link.

Illustratively, the identification information may be a number of the communication link. In this embodiment, the number of the communication link is used as an identification method, which is similar to the step of using the IP address of the server as an identification method, but is only used as an optional implementation manner, and the specific form or content of the identifier is not specifically limited.

As an optional implementation manner of the embodiment of the present invention, as shown in fig. 3, after the original configuration information of the target communication link is updated to the corresponding target configuration information, the method further includes step S204, periodically sending a connection request to the server with a preset time period as a period until the communication link is successfully established with the server.

Specifically, in order to verify that the original configuration information of the managed device is successfully changed into the target configuration information, the managed device sends a connection request to the server, and if the connection is successful within a preset time length, the configuration information is changed; and if the connection fails, re-sending the request to the server at preset time intervals.

The configuration change method provided by the embodiment of the invention is applied to the terminal equipment, firstly, a configuration change instruction which is sent by a server and carries target configuration information corresponding to at least one communication link is received, then, whether the at least one communication link comprises the target communication link used by the terminal equipment is judged, and if yes, the original configuration information of the target communication link is updated to the corresponding target configuration information. The configuration change instruction carries the target configuration information corresponding to the at least one communication link, and the configuration change instruction is used for indicating the terminal equipment to change the original configuration information of the at least one communication link into the corresponding target configuration information, so that when the multilink configuration of the server is changed, each terminal equipment can automatically update the link configuration information used by each terminal equipment, the effect of automatic re-online of each terminal equipment is achieved, and the problem of low change efficiency caused by manual configuration update on a plurality of terminal equipment is solved.

In one embodiment, as shown in FIG. 4, a configuration change method is provided. In this embodiment, the method is mainly applied to a server for example, and includes the following steps:

s401, a configuration change instruction is generated.

The configuration change instruction carries target configuration information corresponding to at least one communication link, and is used for indicating a terminal device using the at least one communication link to change original configuration information of the at least one communication link into corresponding target configuration information.

Illustratively, a manager configures and modifies communication information of each link of a server on a web page of the server, which is called server message ServerConnectInfo for short, and the information comprises an IP address of the server, a monitoring port of the server, a response port of the server and a pre-shared key; the manager can modify the communication information of multiple groups of links at the same time. Specifically, the configuration change instruction may be generated according to the communication information of at least one group of links modified by the administrator.

S402, sending the configuration change instruction to each terminal device so as to change the original configuration information of the at least one communication link into corresponding target configuration information by using the terminal device of the at least one communication link.

As an optional implementation manner of the embodiment of the present invention, an implementation manner of step S402 (sending the configuration change instruction to each terminal device) may include:

and sending the configuration change instruction to each terminal device in a broadcasting mode.

Specifically, broadcast refers to a transmission mode in which the destination address is all devices in the network when packets are transmitted in the computer network. In fact, all devices referred to herein are also limited in scope, referred to as "broadcast domains".

For example, the server information change notification broadcast message may define the following, ServerConnectInfoUpdate _ Notify:

{<ServerConnectInfo_01_Old，ServerConnectInfo_01_New>

<ServerConnectInfo_02_Old，ServerConnectInfo_02_New>，

<ServerConnectInfo_03_Old，ServerConnectInfo_03_New>，

...}

the ServerConnectInfo _01_ Old is the original configuration information of the server link 1, and the ServerConnectInfo _01_ New is the configuration information after the server link 1 is changed.

Other groups are as follows: the meaning of < ServerConnectInfo _02_ Old, ServerConnectInfo _02_ New > data is the same as described above.

As an optional implementation manner of the embodiment of the present invention, as shown in fig. 5, after step S402 (sending the configuration change instruction to each terminal device), the method further includes step S403, in a first preset time period, if a communication link is not successfully established with the terminal device using the at least one communication link, sending the configuration change instruction to each terminal device again.

Specifically, the implementation manner that, within the first preset time period, if the communication link is not successfully established with the terminal device using the at least one communication link, the configuration change instruction is re-sent to each terminal device may be understood as a timeout mechanism, for example, a sends a request, then waits for a response of B, and starts timeout, and if the response is successfully received within the timeout time, waits for the end and ends the timing. If the response is not received within the time-out time, the end of the communication is waited, and meanwhile, the communication fails. In this embodiment, the configuration change instruction may be sent to each terminal device again.

The configuration changing method provided by the embodiment of the invention is applied to a server, firstly, the server generates a configuration changing instruction, and then, the configuration changing instruction is sent to each terminal device, so that the managed device of at least one communication link is used for changing the original configuration information of at least one communication link into the corresponding target configuration information. Furthermore, when the configuration of a plurality of communication links of the server is changed, each terminal device can automatically update the link configuration information used by each terminal device, so that the effect of automatic re-online of each terminal device is achieved, and the problem of low change efficiency caused by manual configuration updating on a plurality of terminal devices is solved.
