Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for checking an IP address.
Background
The BMC (Baseboard Management Controller) is an out-of-band Management system of the server, and may manage and monitor the server based on an IPMI (Intelligent Platform Management Interface) protocol. Moreover, the user can log in a management interface of the BMC through a management interface of the BMC, so that the server is managed and monitored. The premise of logging in the BMC management interface by the user is as follows: the BMC has acquired the IP address and the user knows the IP address of the BMC.
Currently, the modes for BMC to obtain an IP address include statically configuring an IP address and dynamically applying for an IP address. Statically configuring the IP address means: the user directly configures the IP address for the BMC, and the method has the advantages of simple configuration and disadvantages that: the statically configured IP address and the user network may not be in one network segment, and the statically configured IP address may have IP address conflicts. The dynamic application of the IP address means: the BMC requests an IP address from a DHCP (Dynamic Host Configuration Protocol) server, allocates the IP address to the BMC by the DHCP server, and notifies the BMC of the IP address allocated to the BMC.
Whether the IP address is statically configured or dynamically applied, the user may not know the IP address of the BMC, so that the user cannot log in the management interface of the BMC through the management port of the BMC.
For example, after configuring the IP address for the BMC, the user may forget the IP address, or other users may not know the IP address configured for the BMC by the user. After the DHCP server allocates the IP address to the BMC, the user cannot know the IP address allocated to the BMC by the DHCP server.

The embodiment of the application provides a method for viewing an IP address, which can be applied to a system comprising a client and a server, wherein the server comprises a BMC. After the BMC is started, the IP address can be acquired in a static mode or a dynamic mode, and the mode for acquiring the IP address by the BMC is not limited. Moreover, the user can log in a management interface of the BMC through a management interface of the BMC, so that the server is managed and monitored. In order to log in the management interface of the BMC, the user needs to know the IP address of the BMC.
Referring to fig. 1, which is a flowchart of the IP address viewing method provided in this embodiment of the application, a client may obtain an IP address of a BMC, and a user may view the IP address of the BMC through the client. The method can be applied to a client, and the method can comprise the following steps:
step 101, acquiring an identifier corresponding to BMC. The identifier may specifically include, but is not limited to: the MAC address of the BMC, and/or the name of the server. Of course, the identifier may also be other identifiers capable of uniquely representing the BMC, such as an asset number, and the like, and the identifier is not limited thereto.
In one example, a tag may be attached to the server, and the tag may indicate the corresponding identifier of the BMC. The user can obtain the identifier corresponding to the BMC from the tag, and input the identifier corresponding to the BMC into the client, so that the client can obtain the identifier corresponding to the BMC. Of course, the above is only one example that the client acquires the identifier corresponding to the BMC, and the client may also acquire the identifier corresponding to the BMC in other manners, and the acquisition manner of the identifier is not limited in this embodiment.
Step 102, generating an ICMP request message including an identifier corresponding to the BMC. The destination MAC address of the ICMP request message is a broadcast MAC address, the destination IP address is a network segment broadcast address to which the BMC belongs, the source MAC address is an MAC address of the client, and the source IP address is an IP address of the client.
In one example, before generating the ICMP request message, the client may first obtain the network segment address to which the BMC belongs. In order to manage the BMC, the client and the BMC are usually located in the same network segment, and when the client and the BMC are located in the same network segment, the client may determine the network segment address to which the client belongs as the network segment address to which the BMC belongs. For example, when the mask is 24 bits, then an example of a network segment address to which the BMC belongs may be 192.168.0.0/24. Moreover, the client can convert the network segment address 192.168.0.0/24 into the corresponding network segment broadcast address 192.168.0.255, and the detailed conversion process is not repeated.
In one example, for an ICMP request message generated by a client, a destination MAC address of the ICMP request message may be FFFF-FFFF (broadcast MAC address), a destination IP address may be 192.168.0.255 (network segment broadcast address to which BMC belongs), a source MAC address may be a MAC address 00-01-6C-06-a6-29 of the client, and a source IP address may be an IP address 192.168.0.2 of the client.
In one example, the client may generate the ICMP request message described above by the user pinging 192.168.0.255 an IP address on the client. In addition, when the IP address 192.168.0.255 is ping, the identifier corresponding to the BMC may be input after the IP address 192.168.0.255, so that the client may add the identifier corresponding to the BMC to the ICMP request message when generating the ICMP request message. The destination MAC address, the destination IP address, the source MAC address, and the source IP address are all located in the IP header portion of the ICMP request message, and the identifier corresponding to the BMC may be located in the data field portion of the ICMP request message.
Step 103, sending ICMP request message in broadcast mode.
In one example, since the destination MAC address of the ICMP request message is a broadcast MAC address and the destination IP address is a network segment broadcast address to which the BMC belongs, each device in the network segment to which the BMC belongs may receive the ICMP request message, that is, the BMC may receive the ICMP request message.
In one example, after receiving the ICMP request message, if the ICMP request message carries an identifier of the BMC, the BMC sends a first message to the client, where the first message carries an IP address and an MAC address of the BMC. If the ICMP request message does not carry the identifier of the BMC (if the ICMP request message does not carry the identifier or carries the identifier of another device), the BMC discards the ICMP request message.
Specifically, after receiving the ICMP request message, the BMC first checks whether the ICMP request message carries the identifier of the BMC. If not, the ICMP request message is discarded. If the BMC is carried, whether the carried identifier is the identifier of the BMC is checked. If not, the ICMP request message is discarded. If yes, returning a first message carrying the IP address and the MAC address of the BMC. The first message may include, but is not limited to: ARP request message; or an ICMP response message.
In one example, in order to avoid the network problem that the client does not receive the first packet, the BMC may send a preset number (e.g., 5) of first packets, so that the client can receive the first packet.
In one example, in order to enable the client to learn the IP address and the MAC address of the BMC, the source IP address of the first message sent by the BMC to the client is 192.168.0.3 of the BMC, and the source MAC address is 00-01-65-09-a6-38 of the BMC. In addition, the destination IP address of the first message is the IP address 192.168.0.2 of the client, and the destination MAC address is FFFF-FFFF-FFFF.
In one example, for the ICMP request message sent by the client, only the BMC returns the first message, and none of the other devices returns the first message, but directly discards the ICMP request message. Therefore, a large amount of message impact cannot be caused aiming at the ICMP request message sent by the client.
Step 104, receiving a first message sent by the BMC, wherein the first message comprises an IP address and an MAC address of the BMC.
And 105, analyzing the IP address and the MAC address of the BMC from the first message, and recording the corresponding relation between the IP address and the MAC address in an ARP table.
In one example, the first message may be received by the client because the destination MAC address of the first message is FFFF-FFFF. Moreover, the client may also learn the source IP address 192.168.0.3 (i.e., the IP address of the BMC) and the source MAC address 00-01-65-09-a6-38 (i.e., the MAC address of the BMC) of the first packet, and record the corresponding relationship between the IP address 192.168.0.3 and the MAC address 00-01-65-09-a6-38 in a local ARP table. Furthermore, because the corresponding relationship between the IP address 192.168.0.3 of the BMC and the MAC address 00-01-65-09-A6-38 of the BMC is recorded in the ARP table of the client, the user can inquire the IP address 192.168.0.3 of the BMC from the ARP table.
In the above process, it has been described that the user may obtain the identifier corresponding to the BMC, and if the identifier includes the MAC address 00-01-65-09-a6-38 of the BMC, the user may query the ARP table of the client using the MAC address 00-01-65-09-a6-38 of the BMC, so as to obtain the IP address 192.168.0.3 of the BMC. If the identifier does not include the MAC address 00-01-65-09-A6-38 of the BMC, the corresponding relationship between the MAC address of the BMC and the identifier of the BMC can be configured on the client, so that after the user acquires the identifier corresponding to the BMC, the user can obtain the MAC address 00-01-65-09-A6-38 of the BMC corresponding to the identifier of the BMC, and then the user can query the ARP table of the client through the MAC address 00-01-65-09-A6-38 of the BMC, so that the IP address 192.168.0.3 of the BMC can be obtained.
In one example, the following may occur: no IP address is statically configured on the BMC and the DHCP server does not dynamically assign an IP address to the BMC either, resulting in no IP address being available to the BMC. For such a situation, in this embodiment of the application, the client may also allocate an IP address to the BMC, and the ICMP request message sent by the client may also carry the IP address.
Thus, after receiving the ICMP request message from the client, the BMC may directly discard the ICMP request message if the ICMP request message does not carry the identifier of the BMC. If the ICMP request message carries the identifier of the BMC and an IP address, the BMC may process the first message before sending the first message to the client in one of the following two ways:
in the first mode, the BMC firstly judges whether the BMC has an IP address. If yes, the IP address carried by the ICMP request message is discarded. If not, judging whether the IP address carried by the ICMP request message is an available IP address. And if the IP address is the available IP address, setting the IP address carried by the ICMP request message as the IP address of the BMC. And if the IP address is not the available IP address, discarding the IP address carried by the ICMP request message.
And in the second mode, no matter whether the BMC has the IP address, the BMC can directly judge whether the IP address carried by the ICMP request message is the available IP address. If the IP address is available, the BMC may set the IP address carried in the ICMP request message as the IP address of the BMC (if the BMC already has an IP address, the IP address carried in the ICMP request message is used to replace the IP address currently used by the BMC). And if the IP address is not the available IP address, discarding the IP address carried by the ICMP request message.
In one example, a dial switch may be configured on the BMC, and if the dial switch is on, the BMC performs processing in the first mode, and if the dial switch is off, the BMC performs processing in the second mode. Or if the dial switch is on, the BMC adopts the mode two to process, and if the dial switch is off, the BMC adopts the mode one to process.
For the first and second modes, the IP address is carried in the ICMP request message. In one example, the ICMP request message may carry the identifier of the BMC first, and then carry the IP address allocated to the BMC. In another example, the ICMP request message may carry an IP address allocated for the BMC first, and then carry the identifier of the BMC. One or more special characters can be added between the identifier and the IP address, so that the BMC can distinguish the identifier from the IP address based on the special characters.
Aiming at the process that the BMC judges whether the IP address carried by the ICMP request message is an available IP address, the BMC can send a free ARP message, and the target IP address of the free ARP message is the IP address carried by the ICMP request message. If the IP address is already used, the device using the IP address sends an ARP response message to indicate that the device is using the IP address. Based on this, if the BMC receives the ARP response message within the preset time, the IP address is determined not to be the available address. And if the BMC does not receive the ARP response message within the preset time, determining that the IP address is an available address.
Based on the above technical solution, in this embodiment of the application, the client may trigger the BMC to send a first message (such as an ARP request message or an ICMP response message) carrying its own MAC address and IP address by sending an ICMP request message to the BMC, and record a corresponding relationship between the IP address and the MAC address carried in the first message in a local ARP table of the client. Therefore, the user can check the IP address of the BMC from the ARP table of the client, the problem that the user cannot know the IP address of the BMC is solved, and the IP address of the BMC recorded in the ARP table is the latest IP address of the BMC, so that errors cannot occur.
Referring to fig. 2, a flowchart of a method for viewing an IP address provided in an embodiment of the present application is shown, where the method may be applied to a BMC of a server, and the method may include the following steps:
step 201, receiving an ICMP request message from a client.
Step 202, judging whether the ICMP request message carries the identifier of the BMC.
If yes, go to step 203; if not, step 204 is performed.
Step 203, sending a first message carrying the IP address and the MAC address of the BMC to the client, so that the client records the corresponding relationship between the IP address and the MAC address in the ARP table.
Step 204, discarding the ICMP request message.
In one example, the identifier is specifically: MAC address, and/or, name of server; the destination MAC address of the ICMP request message is a broadcast MAC address, the destination IP address is a network segment broadcast address to which the BMC belongs, the source MAC address is an MAC address of the client, and the source IP address is an IP address of the client; the first message specifically includes: ARP request message; or an ICMP response message.
In one example, if the ICMP request message carries an identifier of the BMC and an IP address, before sending the first message carrying the IP address and the MAC address of the BMC to the client:
whether the BMC has an IP address can also be judged; if yes, the IP address carried by the ICMP request message is discarded; if not, judging whether the IP address carried by the ICMP request message is an available IP address; if yes, the IP address carried by the ICMP request message is set as the IP address of the BMC. Or,
directly judging whether the IP address carried by the ICMP request message is an available IP address; if yes, the IP address carried by the ICMP request message is set as the IP address of the BMC.
Based on the above technical solution, in this embodiment of the application, the client may trigger the BMC to send a first message (such as an ARP request message or an ICMP response message) carrying its own MAC address and IP address by sending an ICMP request message to the BMC, and record a corresponding relationship between the IP address and the MAC address carried in the first message in a local ARP table of the client. Therefore, the user can check the IP address of the BMC from the ARP table of the client, the problem that the user cannot know the IP address of the BMC is solved, and the IP address of the BMC recorded in the ARP table is the latest IP address of the BMC, so that errors cannot occur.
Based on the same application concept as the method, the embodiment of the application also provides a viewing device of the IP address, and the viewing device of the IP address is applied to the client. The IP address viewing device may be implemented by software, or may be implemented by hardware, or a combination of hardware and software.
