Detailed Description

In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

Fig. 1 shows a flow chart of a BMC IP obtaining method according to a first embodiment of the present disclosure, as shown in fig. 1, where the method mainly includes:

step S101, under the condition that the baseboard management controller BMC is connected with the current network segment, the communication test is carried out on the IP address of the Internet protocol in the current network segment, a first test result is obtained, and the IP address which indicates successful communication in the first test result is determined as a first address pool.

In this embodiment, first, a connectivity test is performed on an internet protocol (IP, internet Protocol) address in a current network segment under the condition that a baseboard management controller BMC can work normally and is connected with the current network segment, so as to obtain a first test result, and an IP address indicating successful connectivity in the first test result is determined as a first address pool, where if the BMC is connected with a network cable, the BMC is considered to be connected with the current network segment. Specifically, the plurality of IP addresses in the current network segment include the target IP address of the BMC, and since the BMC is connected to the current network segment, the target IP address is capable of being connected when the connectivity test is performed, and the IP address indicating successful connectivity in the plurality of first test results is determined as the first address pool, and the first address pool naturally includes the target IP address of the BMC.

In an implementation manner, an IP address in a current network segment may be subjected to a connectivity test by an nbtsacn command or a ping command, where, when the nbtsacn command performs the connectivity test, a NetBIOS (basic input output system on network) status query is sent to each IP address in the current network segment, and for each IP address responding to the NetBIOS status query, the nbtsacn command lists the corresponding IP address, netBIOS computer name, login user name, MAC address, and so on; when the ping command carries out the connection test, a test data packet is sent to each IP address in the current network segment, response data of the IP address for the test data packet is received, and the response time is counted, so that whether the IP addresses are connected or not is tested.

And step S102, under the condition that the BMC is disconnected from the current network segment, carrying out a connection test on the IP address in the current network segment to obtain a second test result, and determining the IP address which represents successful connection in the second test result as a second address pool.

In this embodiment, a connection test is further required to be performed on the IP address in the current network segment under the condition that the BMC is disconnected from the current network segment, so as to obtain a second test result, and an IP address that indicates that the connection is successful in the second test result is determined as a second address pool, where if the BMC is disconnected from the network cable, the BMC is considered to be disconnected from the current network segment. Specifically, although the plurality of IP addresses in the current network segment include the target IP address of the BMC, the BMC is disconnected from the current network segment, so that the target IP address cannot be connected when the connectivity test is performed, and if the IP address indicating successful connectivity in the plurality of second test results is determined as the second address pool, the second address pool does not include the target IP address of the BMC. Preferably, in step S102, the IP address in the current network segment may also be subjected to the connectivity test by an nbtsacn command or a ping command.

Step S104, determining the target IP address of the BMC according to the target address pool.

In this embodiment, since the first address pool definitely includes the target IP address of the BMC and the second address pool definitely does not include the target IP address of the BMC, the difference between the first address pool and the second address pool is compared, and different IP addresses in the first address pool and the second address pool are determined as the target address pool, so that the target address pool definitely includes the target IP address of the BMC, and the target IP address of the BMC can be determined according to the target address pool.

In one embodiment, if there is only one IP address in the target address pool, the IP address may be determined to be the target IP address of the BMC; if there are multiple IP addresses in the target address pool, for each IP address in the target address pool, respectively performing a connectivity test on the IP address when the BMC is connected to the current network segment and when the BMC is disconnected from the current network segment, and if the IP address is successful in connectivity when the BMC is connected to the current network segment and fails in connectivity when the BMC is disconnected from the current network segment, determining the IP address as the target IP address of the BMC.

In the first embodiment of the present disclosure, the target IP address of the BMC is included in the first address pool obtained when the BMC is connected to the current network segment, the target IP address of the BMC is not included in the second address pool obtained when the BMC is disconnected from the current network segment, and the different IP addresses in the first address pool and the second address pool are used as the target address pools, that is, the target IP address of the BMC is included in the target address pools, so that the target IP address of the BMC can be finally determined according to the target address pools, thereby, when the target IP address of the BMC is obtained, no preparation of a serial port line of the BMC is required, and no opening of the chassis is required to check the MAC address on the motherboard and log in the DHCP server

In the second embodiment of the present disclosure, step S103 mainly includes:

generating a first file according to a first IP address in a first address pool; generating a second file according to a second IP address in the second address pool; and performing difference comparison on the first file and the second file according to the file comparison command to obtain a target address pool.

In this embodiment, when the difference comparison is performed between the first address pool and the second address pool, first, a first file including all the first IP addresses may be generated according to the first IP addresses in the first address pool, then, according to the second IP addresses in the second address pool, a second file including all the second IP addresses may be generated, finally, according to a file comparison command, the difference comparison is performed between the first file and the second file, and a target address pool is formed by different IP addresses in the first address pool and the second address pool.

In an embodiment, all the first IP addresses in the first address pool may be written into the file to obtain a first file, and the second IP addresses in the second address pool may be written into the file to obtain a second file.

In one embodiment, the file comparison command may be a vimdiff command or a grep command, where the vimdiff command may compare and highlight the differential portion of the first file and the second file; the grep command may compare the string data in the first file and the second file, and print out the strings having differences in the first file and the second file.

In the second embodiment of the disclosure, a first file is generated by a first IP address in a first address pool, a second file is generated by a second IP address in a second address pool, and the first file and the second file are subjected to difference comparison according to a file comparison command to obtain a target address pool, so that the efficiency of difference comparison of the first address pool and the second address pool can be improved.

In this embodiment, since there is only one target IP address of the BMC, in an ideal state, there should be only one IP address in the target address pool, but there may also be some interference factors when the BMC is connected to the current network segment, for example, when the BMC is connected to the current network segment, other devices are also connected to the current network segment, and when the BMC is disconnected from the current network segment, the other devices are just disconnected from the current network segment, so that when the IP address in the current network segment is connected to the test, the other devices may affect the number of IP addresses in the target address pool.

In this embodiment, in order to ensure that the number of IP addresses in the target address pool meets a preset threshold, firstly, performing difference comparison on the first address pool and the second address pool to obtain an initial address pool, then judging whether the number of IP addresses in the initial address pool meets the preset threshold, obtaining a judgment result, and if yes, determining the initial address pool as the target address pool; if the judgment result is negative, carrying out connection test on the IP address in the current network segment again under the condition that the BMC is disconnected from the current network segment to obtain a third test result, determining the IP address which is indicated to be successfully connected in the third test result as a third address pool, equivalently adjusting the IP address in the second address pool to obtain a third address pool, carrying out difference comparison on the first address pool and the third address pool until the judgment result is positive, and determining the corresponding initial address pool as a target address pool when the judgment result is positive. Specifically, the preset threshold may be set according to the actual situation, for example, the preset threshold may be 1 to 3.

In a third embodiment of the present disclosure, performing difference comparison on the first address pool and the second address pool to obtain an initial address pool, and judging whether the number of IP addresses in the initial address pool meets a preset threshold value, to obtain a judgment result, if so, determining the initial address pool as a target address pool; if the judgment result is negative, carrying out communication test on the IP address in the current network segment under the condition that the BMC is disconnected from the current network segment again to obtain a third test result, determining the IP address which is indicated to be successfully communicated in the third test result as a third address pool, and carrying out difference comparison on the first address pool and the third address pool until the judgment result is positive. Therefore, interference factors can be eliminated, the number of the IP addresses in the target address pool can meet a preset threshold, and the target IP address of the BMC can be conveniently and subsequently determined according to the target address pool.
