In this video, we’ll explore Wireshark, a powerful network protocol analyzer for capturing and inspecting network traffic in real time. Wireshark is crucial for network troubleshooting, analysis, and security auditing. We’ll begin by covering the basics, including how to install and navigate the software.Next, we’ll dive into hands-on exercises. We’ll analyze HTTP traffic to understand how web browsers interact with servers, diagnose network issues using ICMP packets from ping and traceroute commands, and explore DNS queries to see how domain names are resolved into IP addresses.By the end of this tutorial, you’ll know how to capture, filter, and analyze network traffic, providing you with valuable insights into network behavior and performance.

-- Frequently Asked Questions
✅ Question 1 How can I filter specific types of traffic in Wireshark?
Answer: To filter specific types of traffic in Wireshark, you can use display filters. For example, to view only HTTP traffic, type `http` in the Display Filter box and press Enter. For DNS traffic, use `dns`. You can also combine filters; for instance, `http && ip.addr == 192.168.1.1` will show only HTTP traffic related to a specific IP address. Filters help you focus on relevant data and make analyzing large captures more manageable.
✅ Question 2 What are some common issues I might encounter when using Wireshark?
Answer: Common issues with Wireshark include:
- Missing Packets: This can occur due to high network traffic or insufficient capture buffer size. Ensure your capture settings are optimized and consider increasing buffer size.
- Permissions Issues: On some systems, capturing packets requires administrative or root privileges. Ensure Wireshark has the necessary permissions.
- Large Capture Files: Large files can be difficult to handle. Use capture filters to limit the amount of data collected and manage file size effectively.
