s103, the adjusted target packet is transmitted to the target equipment through the universal channel and the USB male port of the RTOS equipment, so that the packet analysis software of the target equipment receives the adjusted target packet and then performs data analysis on the adjusted target packet.
The packet grabbing method of the embodiment is applied to an RTOS device end, and the specific structure of the RTOS device end is shown in fig. 2. The RTOS device side includes a processor 201, a memory 202 connected to the processor 201, a WiFi (WIreless Fidelity ) driver 203, a USB (Universal Serial Bus ) male port 204, and a WiFi6 network card 205 connected to the WiFi driver 203. The memory 202 is used for storing a related program of the steps of the packet capturing method of the present embodiment, and the processor 201 is used for executing the related program stored in the memory 202. The WiFi driver 203 is configured to drive the WiFi6 network card 205, support the WiFi6 network card 205 to enter the promiscuous listening mode, and support the control/inquiry command of the general channel and the private channel established by the processor 201. The USB male port 204 is configured to perform communication connection with a USB female port of the target device, so that USB interface communication is performed between the RTOS device and the target device.
The following describes in detail the specific implementation steps of the RTOS-based packet capturing method provided in this embodiment with reference to fig. 1 and 2:
before executing step S101, after the RTOS device side starts, it needs to identify whether a connection is established with the target device side. If a USB interface connection request sent by the target equipment end is received, controlling the RTOS equipment end to establish connection with the target equipment end, and identifying that the RTOS equipment end is in a connection state established with the target equipment end. The process of establishing connection between the RTOS equipment end and the target equipment end is that the USB male port of the RTOS equipment end is in physical matching connection with the USB female port of the target equipment end, and then the USB male port 204 and the USB female port are controlled to be in communication connection through a USB driver of the RTOS equipment end. Here, the RTOS equipment end establishes connection with the target equipment end through the USB interface, so that the RTOS equipment end is plug and play, the use is convenient, the response speed is high, and the RTOS equipment end can be powered through the USB interface, namely, the RTOS equipment end has a power supply function.
If the USB interface connection request sent by the target equipment end is not received, the RTOS equipment end is controlled to be in an offline state, and the offline state is a state that the RTOS equipment end and the target equipment end are not connected. It should be noted that the target device includes, but is not limited to, a personal computer and a tablet computer.
After determining that the RTOS device is in the connection state, step S101 is executed, where the RTOS device is in the connection state established with the target device, and a target packet is obtained, where the target packet is a WiFi6 protocol packet, and an operating system of the target device includes a Windows operating system.
Specifically, in the case that it is determined that the RTOS device side is in the connected state, as shown in fig. 3, under the action of the WiFi driver 203, the WiFi6 network card 205 of the RTOS device side acquires the target packet, that is, the WiFi6 network card 205 captures the packet of the 802.11AX protocol in the air in the hybrid interception mode. An operating system is arranged in the target equipment end, and the operating system comprises but is not limited to a Windows operating system or an IOS operating system.
Next, step 102 is executed to perform header adjustment processing on the target packet, so as to obtain an adjusted target packet.
Specifically, the specified header information is added to the target packet to obtain the adjusted target packet, and the specified header information is the header information identified by the packet analysis software. For example, the packet analysis software is wirereshark or tcpdump, and the packet analysis software can identify the target packet through the radio head information, then the radio head information is added to the target packet, so as to obtain an adjusted target packet, and the adjusted target packet is the target packet added with the radio head information. The radio header information includes information such as signal strength, frequency information, noise strength, channel and time stamp. The head adjusting processing enables the target packet to be smoothly transmitted to the packet analysis software of the target equipment end, bypasses the limit of an operating system of the target equipment end, improves the packet grabbing and transmitting efficiency, and has the advantages of convenience in use, convenience in packet processing and the like.
Then, step 103 is executed, and the adjusted target packet is transmitted to the target device through the universal channel and the USB port 204 of the RTOS device, so that the packet analysis software of the target device performs data analysis on the adjusted target packet after receiving the adjusted target packet.
Specifically, after the adjusted target packet is obtained, as shown in fig. 3, the adjusted target packet is transmitted to the target device through a universal channel established by the RTOS device and communicating with the target device and a USB serial port between the RTOS device and the target device under the action of the WiFi6 driver and the driving of the USB port 204.
Under the action of a USB driver of the target equipment end, the target equipment end performs data exchange with the RTOS equipment end, and the control target equipment end receives the adjusted target packet sent by the RTOS equipment end. After receiving the adjusted target packet, the target device transmits the adjusted target packet to packet analysis software installed at the target device under the driving of a network device driver of the target device. The network device driver is a network device driver of an operating system of the target device, for example, the operating system of the target device is a Windows operating system, and the network device driver is a Windows network device driver. After receiving the adjusted target packet, the packet analysis software performs decompression analysis and analysis processing on the adjusted target packet, so that network performance is diagnosed, debugged and monitored rapidly and efficiently.
The principle of the packet grabbing method in this embodiment is that the target device side is usually installed with a Windows operating system, and the Windows operating system only supports related development interfaces for providing the 802.11 BGN protocol, but does not have related development interfaces for the 802.11AX protocol, so that the 802.11AX packet cannot be input into the packet analysis software of the Windows operating system.

Therefore, the target equipment end is not required to be provided with the double systems, time consumption caused by system switching is avoided, data cannot be transmitted due to inconsistency of the double-system file systems, and the situation that the U disk is required to be used for data transmission is avoided.
In the offline state of the RTOS device, as shown in fig. 3, the target packet is acquired through the WiFi6 network card 205 of the RTOS device. And performing head adjustment processing on the target packet to obtain an adjusted target packet, wherein the head adjustment processing process is consistent with the head adjustment processing process under the condition that the RTOS equipment end is determined to be in a connection state. And then, transmitting the adjusted target packet to the network disk through a private channel of the RTOS equipment end so as to enable the network disk to store the target packet. The network disk comprises a NAS network disk.
In addition, for the operation steps executed by the RTOS device end in the offline state, the operation steps of the RTOS device end in the offline state need to be configured in advance by the designated device end, so that the RTOS device end can execute the operation steps in the offline state after being configured. The configuration process specifically includes that firstly, connection is established between an RTOS device end and a designated device end through an mDNS (multicast DNS) protocol. The designated equipment end comprises a personal computer or a tablet personal computer. The designated device side is the device side with application software for configuring the RTOS device side to operate in an offline state. The specific process of establishing connection between the RTOS equipment end and the designated equipment end is that, as shown in fig. 3, the RTOS equipment end is searched and connected with the RTOS equipment end based on the mDNS protocol through a controller and a Windows network interface of the designated equipment end.
And under the condition that the RTOS equipment end establishes connection with the appointed equipment end through the appointed network interface of the appointed equipment end, the RTOS equipment end acquires the configuration information of the network disk sent by the appointed equipment end. The configuration information comprises network addresses of network disks, data compression configuration information and packet grabbing configuration information. The data compression configuration information is related information for judging whether the adjusted target packet needs to be compressed or not, and if the adjusted target packet is compressed and retransmitted, the transmission quantity of data can be reduced, and the space of the NAS network disk can be saved. The packet capturing configuration information is 802.11 packet capturing configuration information, and the packet capturing configuration information is used for configuring the RTOS equipment end to only acquire the related information of the target packet, so that other packets which do not meet the conditions can be filtered out. The packet-grabbing configuration information includes, but is not limited to: channel configuration information, MAC address filtering rules, packet type, protocol type, and port information.
According to the method for grabbing the package, the function of grabbing the package under the WiFi6 protocol is supported in an offline state, so that the package grabbing efficiency is improved, the operating system of the personal computer is not required to be additionally processed, the use is convenient, the power consumption is reduced, and the cost is reduced. The RTOS equipment end supports USB power supply, and the requirements of additional power supply are not needed, so that the RTOS equipment end has the advantages of reducing power consumption, production cost, hardware cost and the like no matter in an offline state or a connection state. The RTOS equipment end supports offline packet capturing data, and sends the data to the network disk for network attached storage in an offline state, and also supports the offline packet capturing data. The packet grabbing method or the RTOS equipment end supports 802.11 n mode and the mcs 0-mcs 9 rate of WiFi. n is any version of the 802.11 mode.
It should be noted that, the general channel is a channel for processing an instruction of the operating system of the target device side, and the private channel is a channel for processing a private instruction of the RTOS device side. For example, if the adjusted target packet needs to be sent to the target device, the adjusted target packet may include a Windows standard command. And the adjusted target packet is sent to the target equipment end through a universal channel by analyzing the Windows standard instruction in the header information of the adjusted target packet.
