Configure Wireshark (Optional):
After installing Wireshark, you may want to configure it to run as a non-root user to enhance security. By default, Wireshark requires root privileges to capture network packets. However, running Wireshark as a non-root user is recommended for security reasons. To configure Wireshark to run as a non-root user, follow these steps:

Add your user account to the wireshark group:

Start Wireshark:
Once installed, you can start Wireshark from the terminal by typing wireshark and pressing Enter. Alternatively, you can launch Wireshark from the desktop environment’s application menu.

Capture Network Traffic:
Upon launching Wireshark, you’ll be presented with the main graphical interface. To begin capturing network traffic, select a network interface from the list and click the ‘Start’ button. Wireshark will start capturing packets on the selected interface, allowing you to analyze the network traffic in real-time.

Analyze Network Traffic:
Once Wireshark is capturing packets, you can analyze the network traffic by applying filters, inspecting packet details, and viewing statistics. Wireshark provides a wide range of tools and features for dissecting network protocols and identifying potential issues or security threats.

By following these step-by-step instructions, you can easily install Wireshark on your CentOS 7 system and start analyzing network traffic like a pro.
