In order to more clearly and completely describe the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The embodiment of the invention provides a method for realizing serial port redirection to remote equipment.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an implementation system for serial port redirection to a remote device provided by the present invention, where the implementation system for serial port redirection to a remote device includes a control device 100, a serial port redirection client 200, and a remote device 300, and the implementation method for serial port redirection to a remote device provided by the embodiment of the present invention is applied to the serial port redirection client 200, so as to redirect an operation request initiated by the control device 100 for the remote device 300 to the remote device 300, so as to facilitate remote control of the remote device 300 by the control device 100.

Further, referring to fig. 2, fig. 2 is a flow chart of a method for implementing serial port redirection to a remote device, where the method for implementing serial port redirection to a remote device is applied to the serial port redirection client shown in fig. 1, where a redirection service component is disposed in the serial port redirection client, and the method for implementing serial port redirection to a remote device may include the following steps S101 to S104.

S101: and acquiring an operation request for the remote equipment, which is initiated by the control equipment.

This step aims at realizing the acquisition of an operation request, which is an operation request for a remote device initiated by a control device, for realizing remote control of the remote device by the control device based on a serial port redirection client (SOL client described below). The type of the operation request is not unique, and may be, for example, an information read operation request, a data write operation request, etc., which is not limited in the present invention.

S102: device information of the control device is determined according to the operation request.

This step aims at enabling the determination of device information of the control device. It can be understood that the control device for remotely controlling the remote device may not be unique, that is, there may be a plurality of control devices capable of remotely controlling the remote device, so that the device information of the control device may be determined first, so that the subsequent target serial port query is realized according to the device information of the control device, and further, the determination of the redirection serial port corresponding to the control device is realized, thereby realizing the automatic serial port switching function.

In the implementation process, the received operation request can be subjected to data analysis, so that the equipment information of the control equipment initiating the operation request can be obtained. The content included in the device information is not unique, and may include, for example, but not limited to, device type/model information, device ID information, device port information, in-device registered user information, in-device registered password information, and the like.

S103: the equipment information is sent to a redirection service component, so that the redirection service component determines a target serial port corresponding to the control equipment according to the equipment information; the redirection service component records the corresponding relation between the equipment information and the serial ports.

The method aims at realizing the query determination of the target serial port. As described above, the SOL client is configured to deploy a redirection service component, where the redirection service component is configured to record correspondence between device information of various control devices and a redirection serial port, so that after obtaining the device information of the control device, the SOL client may send the device information to the redirection service component, and the redirection service component performs serial port query according to the correspondence, and determines a redirection serial port corresponding to the device information, that is, the target serial port corresponding to the determined control device, thereby implementing automatic switching of the redirection serial port.

In a possible implementation manner, the sending the device information to the redirection service component, so that the redirection service component determines, according to the device information, a target serial port corresponding to the control device, may include: and sending the equipment information to the redirection service component so that the redirection service component can check the equipment information by using the record information, and determining a target serial port corresponding to the control equipment according to the equipment information after the equipment information passes the check.

The embodiment of the invention provides a method for realizing redirection serial port inquiry based on a redirection service component. In the implementation process, in order to ensure the validity of the control equipment and further ensure the safety of the remote equipment, after receiving the equipment information of the control equipment, the redirection service component can firstly check the equipment information of the control equipment before carrying out target serial port inquiry on the equipment information, and the check process can be implemented based on the pre-placed record information.

Specifically, in the SOL client research and development process, record information of various control devices can be pre-placed in the redirection service component for storage, the record information essentially refers to standard device information of the corresponding control devices, then the redirection service component can verify the device information by using the record information after obtaining the device information of the control devices, if the device information hits the record information, the control device can be determined to be legal, namely, the verification of the device information is determined to pass, and at the moment, the subsequent redirection serial port inquiry operation can be continuously executed; otherwise, if the device information does not hit the record information, it can be determined that the control device is an illegal device, that is, it is determined that the verification of the device information is not passed, and at this time, the subsequent redirection serial port query operation is not continuously executed.

Therefore, the technical scheme realizes the validity check of the corresponding control equipment by checking the equipment information, can effectively ensure the validity of the control equipment, and further ensures the safety of the remote equipment.

S104: and redirecting the operation request to the remote equipment by utilizing the data transmission channel corresponding to the target serial port.

This step is intended to enable remote redirection of the operation request. After the target serial port corresponding to the control device is determined, the control device can be directly switched to the target serial port, so that the operation request is redirected to the remote device by utilizing the data transmission channel corresponding to the target serial port, and the remote control of the remote device by the control device based on the redirection of the operation request of the control device to the remote device by the SOL client is realized.

In one possible implementation manner, the redirecting the operation request to the remote device by using the data transmission channel corresponding to the target serial port may include the following steps:

judging whether the operation request meets the operation authority;

If not, rejecting the operation request.

The embodiment of the invention provides a method for redirecting an operation request to remote equipment based on a data transmission channel corresponding to a target serial port. It will be appreciated that, for a remote device, different types of control devices may have different operation rights, for example, the remote device may only open read-only rights for one control device and open read-write rights for another control device, so, to avoid unnecessary transmission resource occupation, the remote device may be subjected to rights judgment before redirecting an operation request to the remote device, and only when the rights requirement is met, the operation of redirecting the operation request to the remote device by using the data transmission channel corresponding to the target serial port may be allowed, otherwise, the operation request is refused, i.e. the execution of the subsequent operation is refused.

Specifically, in the process of developing the SOL client, various control devices can be put in advance in the redirection service component to save the operation authority of the remote device, so that the redirection service component can query the operation authority corresponding to the device information and output the operation authority to the SOL client after obtaining the device information of the control device. Further, before redirecting the operation request to the remote device, the SOL client may first determine whether the operation request meets the operation permission, if so, the SOL client may continue to perform the operation of redirecting the operation request to the remote device by using the data transmission channel corresponding to the target serial port, otherwise, the SOL client does not perform the redirection sending on the operation request.

Therefore, before the operation request is redirected to the remote equipment, authority judgment is carried out, the redirection operation of the operation request can be allowed to be executed only when the authority requirement is met, otherwise, the execution is refused, and therefore the operation request redirected to the remote equipment can be effectively guaranteed to be the operation request with legal authority, the operation request which does not have legal authority is prevented from being redirected to the remote equipment, and further unnecessary transmission resource occupation is effectively avoided.

Furthermore, based on the above operation flow, the embodiment of the present invention provides an implementation manner of automatically switching the redirection serial port as follows:

1. and (3) deploying a SOL Server (redirection service component) in the BMC of the SOL client, and configuring the SOL Server, wherein the configuration content mainly comprises record information of each control device, corresponding redirection serial port information, operation authority and the like, and the record information comprises device parameters, device ports, user names, user passwords and the like.

2. When the SOL client is connected to the SOL Server of the BMC, the SOL client provides corresponding user credentials (namely the equipment information) through an authentication mechanism, the SOL Server verifies and matches the user credentials after receiving the user credentials, and if the SOL Server verifies and matches, the user is granted corresponding operation rights. After authorization, the SOL Server can perform corresponding operation according to the operation request and the authority, namely, automatic switching of the SOL data transmission channel corresponding to the redirection serial port is realized.

It can be appreciated that by the above manner, when the matched record information is identified, the automatic switching function can be realized on the SOL data transmission channel without manual operation of a user. Therefore, the operation flow of the user is effectively simplified, and the use convenience of the user is improved; moreover, as the workload of manual intervention of a user is reduced, the possibility of errors can be reduced, so that the reliability and the stability of the system are improved; meanwhile, the user can be more focused on own work, the work efficiency is improved, and the work experience is improved.

In summary, the implementation method for redirecting the serial port to the remote device provided by the embodiment of the invention realizes remote control of the remote device by the control device based on the serial port redirecting client (SOL client), wherein a redirecting service component is deployed in the SOL client and is used for recording the corresponding relation between the device information of various control devices and the redirecting serial port, so that the SOL client can determine the device information of the control device according to the received operation request of the control device for the remote device, and then query a target serial port corresponding to the device information, namely the redirecting serial port corresponding to the control device by utilizing the self redirecting service component, thereby being capable of directly switching to the target serial port, and redirecting the operation request to the remote device by utilizing the data transmission channel corresponding to the target serial port, thereby realizing remote control of the remote device by the control device. Therefore, the technical scheme can realize automatic switching of the redirection serial port in the remote control process based on the SOL function, so that a user can directly realize serial port connection between the local device and the remote device through remote operation without actual physical contact, the usability and convenience of the SOL device are greatly improved, the operation flow is effectively simplified, and the working efficiency is further improved. In addition, based on the implementation mode, development of various switching instructions is not needed in the research and development stage, so that the research and development period is effectively shortened, and the development cost is reduced.

Based on the above embodiments:

in an embodiment of the present invention, before the obtaining the operation request for the remote device initiated by the control device, the method may further include the following steps:

It will be appreciated that the size of the working parameters supportable by each control device may be different from the size of the working parameters supportable by the SOL client, however, if the working parameters of the SOL client and the control device cannot be kept consistent, the problem that the serial port redirection cannot work normally will be caused, for example, if the size of the working parameters supported by the SOL client is far beyond the maximum working parameters supported by a certain control device, the signal noise in the serial port output will be seriously increased, so that the problem of data transmission errors or loss will be caused. Therefore, the embodiment of the invention provides a scheme for realizing the consistency of the working parameters between the SOL client and the control equipment so as to effectively ensure that the serial port redirection can work normally.

In the implementation process, the SOL client can determine the current working parameter of the SOL client, and then send the current working parameter to the control equipment, so that the control equipment can adjust the working parameter of the SOL client according to the current working parameter, and the purpose that the working parameter of the control equipment is matched with the working parameter of the SOL client is achieved. The sending the current working parameter to the control device, so that the control device adjusts the working parameter according to the current working parameter, may include: and the current working parameters are sent to the control equipment through the baseboard management controller, so that the control equipment adjusts the working parameters according to the current working parameters, and the baseboard management controller is deployed at the serial port redirection client.

That is, the SOL client can directly utilize the self-deployed BMC to perform data interaction with the control device, so as to realize the transmission of the working parameters.

In one possible implementation, the above-mentioned operating parameter may specifically be the baud rate.

In one embodiment of the present invention, the implementation method for redirecting the serial port to the remote device may further include the following steps:

receiving a working parameter acquisition request sent by remote equipment;

It will be appreciated that the size of the supportable working parameters of the remote device may be different from that of the SOL client, however, if the working parameters of the SOL client and the remote device cannot be kept consistent, for example, the BMC baud rate of the SOL client is not matched with the BIOS (Basic Input/Output System) baud rate of the remote device, the problem of displaying messy codes will be caused, and the problem of the serial port redirection cannot work normally also exists. Therefore, the embodiment of the invention provides a scheme for realizing the consistency of the working parameters between the SOL client and the remote equipment so as to effectively ensure that the serial port redirection can work normally.

In the implementation process, the remote equipment can actively initiate a working parameter acquisition request to the SOL client, so that the SOL client can respond to the working parameter acquisition request and send the current working parameter of the remote equipment to the remote equipment, so that the remote equipment can adjust the working parameter of the remote equipment according to the current working parameter, and the aim of matching the working parameter of the remote equipment with the working parameter of the SOL client is fulfilled.

The receiving the operation parameter obtaining request sent by the remote device may include: receiving an intelligent platform management interface command (IPMI command) sent by remote equipment; and analyzing and obtaining a working parameter acquisition request according to the intelligent platform management interface command.

The sending the current working parameter to the remote device according to the working parameter obtaining request, so that the remote device adjusts the working parameter according to the current working parameter, may include: and sending the current working parameters to the remote equipment according to the working parameter acquisition request, so that the remote equipment updates the working parameters to the current working parameters by executing the intelligent platform management interface command.

That is, the SOL client may utilize the IPMI command to perform data interaction with the remote device, so as to implement sending and adjusting of the working parameters.

acquiring preset working parameters;

and sending the preset working parameters to the baseboard management controller so that the baseboard management controller can set the preset working parameters as current working parameters, and the baseboard management controller is deployed at the serial port redirection client.

In the embodiment of the invention, the setting or updating of the working parameters in the SOL client can be further realized. Specifically, the method is used for directly inputting preset working parameters, namely the preset working parameters, into the SOL client, so that after the SOL client acquires the preset working parameters, the SOL client can send the preset working parameters to the self BMC, and the BMC sets the preset working parameters as current working parameters.

Furthermore, based on the above embodiments, taking the operating parameter as the baud rate as an example, the embodiments of the present invention provide the following implementation manners of setting and matching the baud rate to be effective immediately:

1. the user sets a new baud rate (preset working parameters) at the SOL client;

2. the SOL client sends the new baud rate information to the BMC itself;

3. after receiving the new baud rate information, the BMC stores the new baud rate information in a corresponding configuration file;

4. The BMC immediately updates the current baud rate setting according to the new baud rate configuration file;

5. after the updating is finished, the BMC sends new baud rate information to the control equipment through the SOL data transmission channel;

6. the control equipment immediately adjusts the baud rate of the serial port communication according to the new baud rate information after receiving the information;

7. the remote device BIOS obtains the current baud rate of the BMC through the IPMI command and compares the current baud rate with the baud rate preset by the BIOS;

8. and comparing the two baud rates, if the two baud rates are the same, continuing the flow, otherwise, changing the baud rate of the BMC SOL baud rate through the IPMI instruction, so that the BMC SOL baud rate can take effect immediately.

It will be appreciated that after the user sets a new baud rate at the SOL client, the BMC will immediately validate the baud rate according to the new setting without performing other operations or restarting the system. The real-time updating method can rapidly and conveniently switch the baud rate of the SOL data transmission channel, and provides more flexible and efficient serial communication experience. Meanwhile, due to the fact that the data transmission channel is updated immediately, a user can communicate and operate at a new baud rate immediately, and working efficiency is improved.

In an embodiment of the present invention, after redirecting the operation request to the remote device by using the data transmission channel corresponding to the target serial port, the method may further include the following steps:

the request response is fed back to the control device.

Based on the above embodiments:

in one embodiment of the invention, a serial port component and a processing component are deployed in a remote device;

the receiving the operation request sent by the serial port redirection client may include: receiving an operation request sent by a serial port redirection client by using a serial port component;

the processing the operation request to obtain the request response may include: processing the operation request by using a processing component to obtain a request response;

the feeding back the request response to the serial port redirecting client may include: and feeding back the request response to the serial port redirection client by using the serial port component.

It will be appreciated that the conventional SOL transfer process is completed by relying on ASCII (American Standard Code for Information Interchange, american standard information interchange code) chips in the remote device, meaning that SOL functionality cannot be used if the remote device does not have an integrated ASCII chip. Thus, this may limit the compatibility of some devices and may require additional hardware support to implement SOL functionality.

Therefore, in order to solve the above technical problems, the embodiment of the present invention implements functional simulation of an ASCII chip by deploying corresponding functional components in a remote device. Specifically, a serial port component and a processing component are deployed in the remote controlled remote device, wherein the serial port component is used for realizing a transmission function, including receiving an operation request and sending a request response, and the processing component is used for realizing a processing function, namely processing the operation request.

In the implementation process, the remote equipment can receive an operation request sent by the SOL client through the serial port component in a redirection way, and the operation request is an operation request of the control equipment to the remote equipment; then, the processing component is utilized to process the request according to the type of the operation request, such as a reading operation, a storing operation, a setting operation, a query operation and the like, so as to obtain a corresponding request response; and finally, feeding back the request response to the control equipment through the SOL client by utilizing the serial port component.

Therefore, the function simulation of the ASCII chip can be realized through the cooperative work of the multifunctional components, and the efficient and reliable data transmission is further realized.

It will be appreciated that different devices may support different data formats, and in order to ensure normal processing of an operation request in the remote device, a conversion module may be further deployed in the remote device, so as to implement a data format conversion function.

Therefore, after the operation request is received based on the serial port component, before the operation request is processed based on the processing component, the conversion component can be utilized to convert the operation request into a preset format, and the preset format is a data format which can be supported by the remote equipment, and then the converted operation request is sent to the processing module for subsequent processing. Correspondingly, in the request response process, after the request response is obtained based on the processing component, before the request response is fed back to the SOL client based on the serial port module, the format of the request response can be converted by the conversion component, and the request response is converted into the initial format of the operation request, and of course, the initial format is a data format supportable by the SOL client, and then the converted request response is sent to the serial port module for request response feedback.

The converting, by the converting component, the data format of the operation request into a preset format, obtaining a converted operation request, and sending the converted operation request to the processing component may include: judging whether the data format of the operation request is a preset format or not through a conversion component; if yes, sending an operation request to a processing component; if not, converting the data format of the operation request into a preset format, obtaining a converted operation request, and sending the converted operation request to the processing component.

As described above, different devices may support different data formats, so the data format of the operation request may be a preset format or may not be a preset format, so the data format may be determined first, if the data format meets the preset format, the data format conversion operation is not required to be executed, and the operation request is directly sent to the processing component; otherwise, if the data format of the operation request is the preset format, the data format conversion operation is executed again, so that the converted operation request is sent to the processing component.

In one embodiment of the invention, a storage component is also disposed in the remote device; the implementation method for redirecting the serial port to the remote equipment can further comprise the following steps:

Recording processing information corresponding to the operation request and the request response;

It may be understood that during the processing of the operation request, temporary storage and buffering of relevant data may be involved, so that a storage component may be disposed in the remote device, so as to implement storage of the operation request and the request response and relevant information of the operation request and the request response (i.e. the above processing information), where the processing information refers to various data information generated during the processing and the transmission of the operation request and the request response, and specifically may be recorded in real time through a serial port component, a processing component, and a conversion component, and forwarded to the storage component for storage.

3. Serial port assembly:

the serial port component receives data from the control equipment, and temporarily stores the data in the transmission shift register through the transmission data register, and waits for the transmitter to send out a signal; the transmitter is controlled by the transmitter clock module and transmits a corresponding signal to the transmission shift register after the timing sequence is completed, so that the transmission shift register transmits data to the conversion component after receiving the signal. In addition, the conversion component converts the data and then sends the converted data to the receiving shift register for the storage component to read.

4. And a conversion component:

when power is on, the conversion component firstly initializes communication parameters, pins, priority and the like and waits for receiving data. When the data is sent, whether the data format is a preset format is judged, if not, the data is standardized according to the preset format, otherwise, the data is sequentially stored in a receiving array and packaged.
