The present invention provides a kind of Network Mirror packet snapping method.
In network interface card mirror image packet capturing section method first embodiment of the present invention, referring to Fig. 3, network interface card mirror image packet snapping method includes:
Step S10, configures mapping block, and by being associated with to the progress of packet capturing network interface card and mirror port and the mapping block
Configuration；
Specifically, (meaning of addition is addition mapping block, through software in trawl performance first in trawl performance
Increase mapping block, make it have corresponding function), mapping block will be associated to packet capturing network interface card with mirror port,
By mapping block, mirror port can treat packet capturing network interface card and carry out mirror image.
Step S20 generates the mirror image to packet capturing network interface card by mapping block in mirror port；
Specifically, trawl performance can get the message to packet capturing network interface card first, then will be to packet capturing by mapping block
The message of network interface card maps in mirror port, and then mirror port regenerates the mirror image to packet capturing network interface card.
Step S30 carries out packet capturing to the mirror image in mirror port, obtains the message of mirror port.
Specifically, mirror port is different to packet capturing network interface card, and mirror port is that physical host can be checked directly (i.e. excessively
The port data can be directly acquired) a PCI (Peripheral Component Interconnect, external components are mutual
Even standard) equipment, therefore physical host can carry out packet capturing to mirror port, and the message of mirror port is to pass through mapping
The mirror image message to packet capturing network interface card that module generates, therefore the message for obtaining mirror port can be considered acquisition to packet capturing network interface card
Message.
Mapping block is configured in trawl performance first, and mapping block can reflect the message to packet capturing network interface card
It penetrates, is mapped in mirror port, to generate the mirror image to packet capturing network interface card in mirror port.And to packet capturing network interface card due to not straight
It connects and is connect with physical host, therefore physical host can not directly treat packet capturing network interface card and carry out packet capturing, but physical host can lead to
It crosses the packet catchers such as TcpDump and packet capturing directly is carried out to mirror port, and the message in mirror port is by reflecting to packet capturing network interface card
It penetrates, therefore is identical with the message to packet capturing network interface card, therefore the message for obtaining mirror port can be considered and obtain
To the message of packet capturing network interface card, that is, complete the packet capturing for treating packet capturing network interface card.
It has found broad application in computer technology in virtualization technology at present, such as network interface card passes through SR-IOV
(Single-root I/O virtualization, single I/O virtualization) realizes multiple Microsoft Loopback Adapter (VF, Virtual
Function), each virtual machine (VM, Virtual Machine) distributes a certain number of Microsoft Loopback Adapters according to demand, then each
Microsoft Loopback Adapter be a PCI true (Peripheral Component Interconnect Express, it is quickly outer
If component interconnects), for the equipment through the direct carry of hardware-switch of network interface card itself in virtual machine, virtual machine can check it certainly
The device PCI of body carry, but this physical host can't load this device PCI, therefore physics for cloud platform
Host then cannot achieve in the port packet capturing (schematic diagram of a scenario such as Fig. 4) to the device PCI.
Desired to solve the problems, such as packet capturing of the physical host for network interface card in a virtual machine environment, how first have to solve makes object
Reason host can check (or being attached, refer to that foundation can make physical host complete the incidence relation to network interface card packet capturing) not
Network interface card connected to it, it is however generally that be by increasing external equipment or modifying the setting of outside network device by operator
To reach the purpose.But current method has and increases additional use cost (increasing additional external equipment), right
The drawbacks such as the technical requirements of operator higher (setting for changing outside network device), increase the packet capturing cost of user.
Thus port message to packet capturing network interface card is mapped to by the present invention then by increasing mapping block in trawl performance
In mirror port (mirror port is the network interface card port that physical host can directly carry out packet capturing), then there is mirror image in mirror port
The message to packet capturing network interface card.Physical host then can obtain the report of mirror port by carrying out packet capturing to mirror port at this time
Text, since the message of mirror port is to wait for packet capturing network interface card by mirror image and obtain, the message of mirror port with to packet capturing network interface card
Message be identical, therefore physical host is by carrying out packet capturing and report of the indirect gain to packet capturing network interface card to mirror port
Text, therefore be equivalent to by adding mapping block in trawl performance, so that physical host and to be established between packet capturing network interface card
Indirect connection relationship, to realize the packet capturing (usage scenario schematic diagram such as Fig. 5 of the present invention) for treating packet capturing network interface card.
Packet capturing is one of most common technology in current network communication technology, and packet capturing is to send and receive network transmission
The operations such as data packet intercepted and captured, retransmitted, edited, unloading are commonly used to check network security or carry out interception prison to data
Control.It is further after acquisition data packet by the data packet mutually transmitted between packet capturing acquisition network especially in network safety filed
The content of data packet is analyzed, judge data packet whether include menace network safety content.In addition to this, in software
In exploitation also software test can be carried out by packet capturing.After finding the problem, data flow, the log etc. of mistake are obtained by packet capturing
Data, tester can be by reappearing mistake, the modes orientation problem such as data intercept.
In practice, the application scenarios of packet capturing also have various different situations, and the following are several typical application scenarios
Be briefly described and process: Fig. 6 is described at the same physical host HOST, virtual machine VM2 pass through Microsoft Loopback Adapter VF2 (mirror
As port) grab the scene of the message of the port Microsoft Loopback Adapter VF1 (to packet capturing network interface card) in virtual machine VM1.Fig. 7 is then in Fig. 6
In connection relationship under scene, in virtual machine VM1 Microsoft Loopback Adapter VF1 (to packet capturing network interface card) with it is virtual under the same physical host
The packet capturing interactive process of machine VM2 (mirror port)；Fig. 8 describe physical host HOST by with remove the Microsoft Loopback Adapter VF2 connecting
(mirror port) grabs the scene of Microsoft Loopback Adapter VF1 (to packet capturing network interface card) message in virtual machine VM1 by mirror port.Fig. 9 description
In the connection relationship under Fig. 8 scene, the Microsoft Loopback Adapter VF2 (mirror port) in physical host HOST grabs virtual machine VM1
In Microsoft Loopback Adapter VF1 (to packet capturing network interface card) packet capturing interactive process；Figure 10 describes physical host HOST and virtual machine VM2,
By OVS bridge mirror image and Microsoft Loopback Adapter VF2 (mirror port), mirror image grabs the Microsoft Loopback Adapter VF1 in virtual machine VM1 (to packet capturing net
Card) message scene.Figure 11 is described in the connection relationship under Figure 10 scene, in physical host HOST and virtual machine VM2
Friendship of the Microsoft Loopback Adapter VF2 (mirror port) to Microsoft Loopback Adapter VF1 (to packet capturing network interface card) mirror image packet capturing in another virtual machine VM1
Mutual process.
The present invention will need the Network card setup of packet capturing into trawl performance by the way that mapping block is arranged in trawl performance,
And image feature is completed by trawl performance, and host then can be by dedicated packet catcher (TcpDump etc.) to mirror port
Message is grabbed, and the packet capturing of itself Microsoft Loopback Adapter is asked to solve the virtual machine of SR-IOV network interface card in a virtual machine environment
Topic.By the invention it is possible in the case where not increasing additional external equipment and not changing external setting configuration
Complete the packet capturing for Microsoft Loopback Adapters all in virtual machine port.And it is low using difficulty, it is easy to use, and by network interface card
The fault location of network data exception is realized in mirror image packet capturing, and to important operations such as the traffic monitorings of network.
Further, step S10 will be carried out and the associated configuration of the mapping block to packet capturing network interface card and mirror port
Step includes:
Step S11, selectes mirror port, and the mirror port is the port that physical host can directly carry out packet capturing.
Specifically, in order to be got by mirror port to the message in packet capturing network interface card port, mirror port needs
It can be loaded by physical host, i.e., physical host can carry out packet capturing to mirror port.
After setting mapping block in trawl performance, need to select a network interface card port as mirror port, and
Mirror port is and physical host to be made to obtain the message in the mirror image by packet capturing to store the mirror image to packet capturing network interface card,
Therefore mirror port is that mirror port can be loaded by physical host from the place different to packet capturing network interface card and (is to packet capturing network interface card
What physical host can not load, therefore physical host can not treat packet capturing network interface card and directly carry out packet capturing), so that physical host can
Packet capturing directly is carried out to mirror port, obtains the message in mirror port.Made by selecting the port that physical host can load
For mirror port, physical host is enabled directly to carry out packet capturing to mirror port, to quickly obtain in mirror port
Message.
Further, step S20, the step of generating the mirror image to packet capturing network interface card in mirror port by mapping block, wrap
It includes:
Step S21 obtains the message to packet capturing network interface card, message is mapped to mirror port by mapping block.
Specifically, when treating packet capturing network interface card progress mirror image by mapping block, mapped port can be got to packet capturing first
The data that network interface card sends and receives, the data that then will acquire are sent in mirror port, and are generated in mirror port
Mirror image to packet capturing network interface card.Treat mapping block to packet capturing network interface card carry out mirror image, be substantially exactly treat packet capturing network interface card receive with
The data of transmission are replicated, and the data of duplication are sent to mirror port so that the data in mirror port with to
Packet capturing network interface card it is identical.
By mapping block, can will be received to packet capturing network interface card and be sent to mirror port with the data sent, with generate to
The mirror image of packet capturing network interface card.Mirror port after completing mirror image, physical host can be got by packet capturing in mirror port to
The mirror image of packet capturing network interface card, so that physical host realizes the packet capturing for treating packet capturing network interface card.
Further, such as Fig. 3, step S30, packet capturing is carried out to the mirror image in mirror port, obtains the message of mirror port
The step of include:
Step S31 grabs mirror port by default packet catcher based on physical host after receiving packet capturing instruction
Packet.
Specifically, mirror port is completed after treating the mirror image of packet capturing net A Kui, in the packet capturing for receiving physical host transmission
When instruction, physical host then passes through packet catcher and grabs to the mirror image message in mirror port, to obtain the report of needs
Text.
After setting the mirror image message for needing the network interface card of packet capturing in mirror port, physical host can then need packet capturing
When by trawl performance obtain target network interface card mirror image message.By packet catcher, (such as TcpDump etc. is grabbed physical host
Job contract tool) crawl mirror port message.
There is register inside SR-IOV network interface card itself, the mirror image of source purpose can be set, but since what is do not driven connects
Mouth and realization, therefore physical host can not arbitrarily carry out the packet capturing to network interface card, and the present invention in trawl performance by establishing
Mapping block, and the bridge between physical host and the target network interface card for needing packet capturing is established by mapping block.Therefore it solves
The problem of physical host directly can not be checked to the Microsoft Loopback Adapter of carry on a virtual machine and (carry out the operation such as packet capturing), physics
Host is by checking trawl performance, and trawl performance completes the mirror image packet capturing to network interface card by mapping block, to realize
Mirror image packet capturing to network interface card.
Further, such as Fig. 3, step S31, packet capturing is carried out to mirror port by presetting packet catcher based on physical host
Include: after step
Step S32 records packet capturing duration, and is compared with default packet capturing duration, according to packet capturing duration and default packet capturing
The comparison result of duration controls whether to stop packet capturing.
Specifically, when starting packet capturing, the packet capturing time started is recorded, during packet capturing carries out, current time, which subtracts, is grabbed
Packet the time started packet capturing duration can be obtained, packet capturing duration and default packet capturing duration are compared, come determine whether to continue into
Row packet capturing, so as to accurately control the data volume of this packet capturing.
Packet capturing be exactly the data packet for sending and receiving network transmission intercepted and captured, retransmitted, being edited, the operation such as unloading, because
The target of this packet capturing is data, and with the increase of packet capturing duration, the data volume of packet capturing can also increase therewith.And the increasing of data volume
Add meeting so that the occupied resource of the message of crawl increases, and excessively huge data are also unfavorable for subsequent interpretation.Therefore
The data grabbed are controlled in suitable size, can either disposably get enough data volumes in this way, and will not be because of
The problems such as excessively huge caused occupancy resource of data is excessive, and reading speed is slow.It, then can be with and by the control to packet capturing duration
Achieve the purpose that the amount of control crawl data then shows to have grabbed foot when packet capturing duration reaches preset packet capturing duration
The message of enough evidences needs to stop packet capturing at this time, in order to avoid the message data of crawl is excessively huge, degree storage and reading are caused not
Just.
Further, step S32 controls whether to stop packet capturing according to the comparison result of packet capturing duration and default packet capturing duration
The step of after include:
Step S33, when packet capturing duration is less than default packet capturing duration, then persistently packet capturing；
Step S34 then stops packet capturing when packet capturing duration is greater than or equal to default packet capturing duration.
Specifically, packet capturing duration determines the total amount of data of this packet capturing, preset duration be according to packet capturing demand with it is soft or hard
Part conditional decision, after setting preset duration, controlled whether according to the relationship of the packet capturing duration of record and preset duration
Stop packet capturing.
The data volume that packet capturing obtains increases with the increase of packet capturing duration, and needs to grab the how many data in port then root
It is adjusted according to different situations.If the data volume of crawl is very little, then the purpose of carrying out data monitoring or network security
It is that may lead to not obtain accurate information due to data deficiencies.If the data volume of crawl is too many, then may lead
Storage or transmission inconvenience is caused even to fail, and excessive data can only make efficiency of the user when analyzing become
It is low, and precision of analysis can not be obviously improved.After default packet capturing duration thus is set according to specific demand, grab
Packet capturing duration is compared Bao Shihui with default packet capturing duration, is determined by comparison result and continues packet capturing or stopping packet capturing,
So as to be accurately controlled the data volume of port crawl.
Further, then stop packet capturing when packet capturing duration is greater than or equal to default packet capturing duration such as Fig. 3, step S34
The step of after include:
The message that the packet capturing obtains is stored in default local path by step S341 after stopping packet capturing.
After packet capturing, the port data (i.e. the message of packet capturing acquisition) that will acquire is locally stored, stores path
For preset local path.
After packet capturing, the message of acquisition needs the local path of a specified storage, so that message is locally stored
In.It is locally stored to enable a technician to preferably locally using the message of crawl, specifying a locally-stored road
Diameter be it is necessary, technical staff can then get locally-stored message according to specified path when needed, to realize
The work such as the analysis to local data.
Further, step S34, when packet capturing duration is greater than or equal to default packet capturing duration, then the step of stopping packet capturing
Further include:
Step S342 sends preset far-end address by network for the message that the packet capturing obtains after stopping packet capturing.
Specifically, other than the message of crawl is stored in specified local path, can also be arranged the message of crawl
It is sent to far-end address, to realize the long-range monitoring and analysis to network data of technical staff.
In network monitoring or network safety filed, it is however generally that a small amount of manager device can be set for entire net
Equipment in network is monitored and manages.And technical staff can unify to carry out all devices in network by manager device
Management, but manager device needs to get the packet capturing data of other equipment in network, and in order to obtain administrator
The device port data for needing to be monitored into whole network are then needed through the port progress packet capturing to equipment, and
The port data that will acquire after packet capturing is sent to far-end address (the far-end address i.e. computer address of administrator), to realize
The computer operations such as long-range monitoring.Network interface card mirror image packet snapping method of the present invention in addition to can by packet capturing data storage in local other than,
The address that packet capturing data are sent to distal end by network can also be set, in this way, which technical staff can then pass through management
