A kind of inspection method of IP address is proposed in the embodiment of the present application, the method can apply to include client kimonos
In the system of business device, BMC is included on the server.Wherein, BMC upon actuation, can be by static mode or dynamical fashion
IP address is obtained, for the mode that BMC obtains IP address is not limited.And, user can be logged in by the management mouth of BMC
The administration interface of BMC, so as to being managed to server and monitoring.In order to log in the administration interface of BMC, user needs to know
The IP address of BMC.
It is shown in Figure 1, it is the flow chart of the inspection method of the IP address proposed in the embodiment of the present application, client can be with
The IP address of BMC is got, and user can check the IP address of BMC by the client.Wherein, the method can apply to
Client, and the method may comprise steps of：
Step 101, obtains the corresponding marks of BMC.Wherein, the mark specifically can be including but not limited to：The MAC ground of BMC
Location, and/or, the title of server.Certainly, the mark can also be that other can uniquely represent the mark of the BMC, and such as assets are compiled
Number etc., this mark is not limited.
In one example, one can be on the server labeled, the label writes the corresponding marks of BMC exactly.User can
To obtain the corresponding marks of BMC from the label, and the corresponding marks of BMC are input on the client, so that client gets
The corresponding marks of BMC.Certainly, above-mentioned simply client gets an example of the corresponding marks of BMC, and client can also lead to
Cross alternate manner and get the corresponding marks of BMC, the acquisition modes identified to this in the embodiment of the present application are not limited.
Step 102, generation includes the ICMP request messages of the corresponding marks of the BMC.Wherein, the mesh of the ICMP request messages
MAC Address be broadcast MAC address, purpose IP address are the network segment broadcast addresses belonging to BMC, and source MAC is client
MAC Address, source IP address is the IP address of client.
In one example, before ICMP request messages are generated, client can first obtain the network segment ground belonging to BMC
Location.In order to be managed to BMC, client is usually located at the same network segment with BMC, when client and BMC are located at same net
Duan Shi, client can be by the network segment address belonging to itself, the network segment address being defined as belonging to BMC.For example, when mask is 24
When, then the network segment address belonging to BMC a example can be 192.168.0.0/24.And, client can be by network segment address
192.168.0.0/24 being converted to corresponding network segment broadcast address 192.168.0.255, specific transfer process is repeated no more.
In one example, the ICMP request messages for generating for client, the target MAC (Media Access Control) address of the ICMP request messages
Can be FFFF-FFFF-FFFF (broadcast MAC address), purpose IP address can be the 192.168.0.255 (network segments belonging to BMC
Broadcast address), source MAC can be the MAC Address 00-01-6C-06-A6-29 of client, and source IP address can be client
IP address 192.168.0.2 at end.
In one example, user passes through mono- IP address 192.168.0.255 of ping on the client, and client can
To generate above-mentioned ICMP request messages.And, in ping IP address 192.168.0.255, can be in the IP address
192.168.0.255 the corresponding marks of input BMC after, so, client is when above-mentioned ICMP request messages are generated, it is possible to
The corresponding marks of BMC are added in ICMP request messages.Wherein, ICMP request messages can include IP heads point and data field
Part, above-mentioned purpose MAC Address, purpose IP address, source MAC and source IP address are respectively positioned on the IP heads of ICMP request messages
Point, and the corresponding marks of BMC may be located at the data field part of ICMP request messages.
Step 103, with broadcast mode ICMP request messages are sent.
In one example, because the target MAC (Media Access Control) address of ICMP request messages is broadcast MAC address, purpose IP address are
Network segment broadcast address belonging to BMC, therefore, each equipment in the affiliated network segments of BMC can receive the ICMP request messages, i.e.,
BMC can receive the ICMP request messages.
In one example, BMC is after the ICMP request messages are received, if the ICMP request messages carry this BMC's
Mark, then to client the first message of transmission, first message carries the IP address and MAC Address of this BMC to BMC.If the ICMP
Request message does not carry the mark (as do not carried mark or carrying the mark of miscellaneous equipment) of this BMC, then BMC is abandoned and is somebody's turn to do
ICMP request messages.
Specifically, BMC first checks in ICMP request messages whether carry this BMC's after ICMP request messages are received
Mark.If do not carried, the ICMP request messages are abandoned.If carried, check that what is carried identifies whether as this BMC's
Mark.If it is not, then abandoning the ICMP request messages.If it is, returning the IP address and MAC Address for carrying this BMC
First message.Wherein, first message can be including but not limited to：ARP request message；Or, ICMP response messages.
In one example, in order to avoid network problem causes client to be not received by the first message, then BMC can send out
Send predetermined number (such as 5) individual first message, to enable the client to receive the first message.
In one example, in order that the IP address and MAC Address of this BMC is arrived in client study, BMC to client sends
The first message source IP address be this BMC IP address 192.168.0.3, source MAC is the MAC Address 00- of this BMC
01-65-09-A6-38.Additionally, IP address 192.168.0.2 of the purpose IP address of the first message for client, purpose MAC ground
Location is FFFF-FFFF-FFFF.
In one example, the ICMP request messages for sending for client, only BMC can return the first message, and its
Its equipment will not return the first message, but directly abandon ICMP request messages.Therefore, the ICMP for sending for client please
Message is sought, substantial amounts of message impact is not resulted in.
Step 104, receives the first message that BMC sends, and first message includes the IP address and MAC Address of BMC.
Step 105, parses the IP address and MAC Address of BMC from first message, and the IP is recorded in ARP table
Address and the corresponding relation of the MAC Address.
In one example, because the target MAC (Media Access Control) address of first message is FFFF-FFFF-FFFF, therefore, client
First message can be received.And, client can also learn the source IP address 192.168.0.3 of first message (i.e.
The IP address of BMC) and source MAC 00-01-65-09-A6-38 (i.e. the MAC Address of BMC), and remember in local ARP table
Record the corresponding relation of IP address 192.168.0.3 and MAC Address 00-01-65-09-A6-38.Further, due to client
The corresponding of IP address 192.168.0.3 of BMC and the MAC Address 00-01-65-09-A6-38 of BMC is have recorded in the ARP table at end
Relation, therefore, user can inquire IP address 192.168.0.3 of BMC from the ARP table.
Make referrals in above process, user can get the corresponding marks of BMC, if the mark includes BMC's
MAC Address 00-01-65-09-A6-38, then user can be using the MAC Address 00-01-65-09-A6-38 of BMC inquiry clients
The ARP table at end, such that it is able to obtain IP address 192.168.0.3 of BMC.If the mark is not including the MAC Address 00-01- of BMC
65-09-A6-38, then can also on the client configure the corresponding relation of the MAC Address of BMC and the mark of BMC, so, user
After getting the corresponding marks of BMC, the MAC Address 00-01-65-09-A6-38 of the corresponding BMC of mark of BMC can be obtained, so
Afterwards by the ARP table of the MAC Address 00-01-65-09-A6-38 inquiring client terminals of BMC, such that it is able to obtain the IP address of BMC
192.168.0.3。
In one example, it is possible that following situation：No static configuration IP address on BMC, and DHCP service
Device is also not BMC dynamic IP address allocations, does not have available IP address so as to cause BMC.For such case, the application reality
In applying example, client can also distribute an IP address for BMC, and in the ICMP request messages that client sends, can be with
Carry the IP address.
So, BMC is being received after the ICMP request messages of client, if the ICMP request messages do not carry this
The mark of BMC, then can directly abandon the ICMP request messages.If ICMP request messages carry the mark of this BMC and one
IP address, then BMC to client send the first message before, can be in a kind of mode using the following two kinds mode at
Reason：
Mode one, BMC first judges whether this BMC has IP address.If it is, abandoning the IP ground that ICMP request messages are carried
Location.If it is not, then judging whether the IP address that ICMP request messages are carried is available IP address.If IP address can be used, then
The IP address that ICMP request messages are carried is set to into the IP address of this BMC.If not available IP address, then abandoning ICMP please
The IP address for asking message to carry.
Whether mode two, no matter this BMC have had IP address, and BMC can directly judge what ICMP request messages were carried
Whether IP address is available IP address.If IP address can be used, then BMC can set the IP address that ICMP request messages are carried
The IP address for being set to this BMC (if this BMC has had IP address, has been replaced using the IP address of ICMP request messages carrying
The IP address that this BMC is being currently used).If not available IP address, then the IP address that ICMP request messages are carried is abandoned.
In one example, a toggle switch can be configured on BMC, if the toggle switch is to open, BMC is adopted
Mode one is processed, if the toggle switch is to close, BMC employing modes two are processed.Or, if the toggle switch
To open, then BMC employing modes two are processed, if the toggle switch is to close, BMC employing modes one are processed.
For mode one and mode two, IP address is carried in ICMP request messages.In one example, please in ICMP
Asking can first carry the mark of BMC in message, then carry the IP address for BMC distribution.In another example, please in ICMP
The IP address that can first carry in message as BMC distribution is sought, the mark of BMC is then carried.Wherein, in the mark and the IP address
Between, one or several spcial characters can also be added, so that BMC distinguishes the mark and the IP ground based on these spcial characters
Location.
For the process of " BMC judges whether the IP address that ICMP request messages are carried is available IP address ", BMC can send out
Gratuitous ARP packet is sent, the purpose IP address of the gratuitous ARP packet are the IP address that ICMP request messages are carried.If the IP address
Used, then will be sent arp response message using the equipment of the IP address, represented that the equipment is currently in use this IP ground
Location.Based on this, if BMC receives arp response message in Preset Time, it is determined that the IP address is not available address.Such as
Fruit BMC does not receive arp response message in Preset Time, it is determined that the IP address is available address.
Based on above-mentioned technical proposal, in the embodiment of the present application, client can by BMC send ICMP request messages,
Triggering BMC sends the first message of the MAC Address and IP address for carrying itself (such as ARP request message or ICMP response reports
Text etc.), and the corresponding relation of the IP address and MAC Address carried in the first message is recorded in the local ARP table of client.This
Sample, user just can check the IP address of BMC from the ARP table of client, and solving user cannot know the IP address of BMC
The IP address of the BMC recorded in problem, and ARP table is the newest IP address of BMC, is not in mistake.
It is shown in Figure 2, it is the flow chart of the inspection method of the IP address proposed in the embodiment of the present application, the method can be with
The BMC of server is applied to, and the method may comprise steps of：
Step 201, receives the ICMP request messages from client.
Step 202, judges whether the ICMP request messages carry the mark of this BMC.
If it is, execution step 203；If it is not, then execution step 204.
Step 203, the first message for carrying the IP address with MAC Address of this BMC is sent to client, so that client exists
The corresponding relation of the IP address and the MAC Address is recorded in ARP table.
Step 204, abandons the ICMP request messages.
In one example, the mark is specially：MAC Address, and/or, the title of server；ICMP request messages
Target MAC (Media Access Control) address is broadcast MAC address, and purpose IP address are the network segment broadcast addresses belonging to BMC, and source MAC is client
MAC Address, source IP address is the IP address of client；First message is specially：ARP request message；Or, ICMP response reports
Text.
