To capture and analyze network traffic using Wireshark, you can follow these steps: 1. Start Wireshark: Open the Wireshark application on your computer. 2. Select the network interface: In the main Wireshark window, you will see a list of available network interfaces. Choose the interface through which you want to capture the network traffic. For example, if you are connected to the internet via Wi-Fi, select the Wi-Fi interface. 3. Start capturing packets: Click on the "Capture" menu and then select "Start" or click on the "shark fin" icon. Wireshark will start capturing packets from the selected interface. 4. Analyze captured packets: Once you have captured enough packets, you can stop the capture by clicking on the "Capture" menu and selecting "Stop" or by clicking on the "shark fin" icon again. The captured packets will be displayed in the main Wireshark window. 5. Analyze packet content: You can analyze the content of each packet by selecting it in the packet list. The details of the selected packet will be displayed in the packet details pane below. Wireshark provides various information about each packet, such as source and destination IP addresses, protocols used, packet length, and more. 6. Use packet filters: Wireshark allows you to apply filters to the captured packets to focus on specific types of traffic or specific network conversations. You can use filters to search for specific protocols, IP addresses, ports, or any other criteria. 7. Interpret packet colors: Wireshark uses colors to indicate the type of packet and whether it has been performed correctly. For example, green packets indicate successful transmissions, while red packets indicate errors or dropped packets. Remember that capturing network traffic with Wireshark may require administrative privileges on your computer, and it's important to use it responsibly and in compliance with applicable laws and regulations.
