Wireshark is a capture software that can capture data packets on the network in real time and present them in an easy-to-understand format. This allows network engineers to gain insight into the details of network traffic, including packet size, source address, destination address, transport protocol, and data content. This is critical for diagnosing network problems, optimizing network performance, and ensuring network security. Next, let the editor of Huajun explain to you how to capture packets with wireshark and how to capture packets with wireshark!
first step
When Wireshark is first opened, it displays a list of all network interfaces available on the computer (e.g. Ethernet, WLAN, etc.). Next select the WLAN2 interface. Please choose the correct interface according to your actual situation.
Step 2
Once you select an interface, Wireshark will automatically start capturing packets on that interface. You will see the captured packets displayed in a list in Wireshark's main window.
Step 3
Packet capture results are usually displayed in three sections:
At the top is a list of all captured packets.
In the middle is the detailed information of the selected data packet, including protocol layer, source address, destination address, etc.
At the bottom is the actual machine code of the packet (in hexadecimal representation).
Step 4
At the top of Wireshark, there is a search bar where you can enter a specific protocol or content to filter packets. In your example, "http" was entered to limit the kinds of packets captured.
Step 5
After setting up filters, you can refresh a website or perform the web activity you want to monitor. Wireshark will only capture packets that meet the filter criteria.
Step 6
After you capture the packets, you can analyze them carefully to understand the details of your network traffic. You can use various tools and functions provided by Wireshark to analyze packets in depth, such as protocol analyzer, traffic graph, etc.
Step 7
When you finish capturing packets, you can click the red stop button on the Wireshark interface to stop capturing.
The above is how to capture packets with wireshark and the method of capturing packets with wireshark compiled by Huajun editor for you. I hope it can help you!
