How to use captures to troubleshoot both common and complex problems, such as TCP retransmissions and Black Hole routersĪdditionally, you will receive access to all of the example traces used in the course, so that you can follow along as the instructor walks you through his techniques. How to use RFCs to understand the function of the protocols you are examining
How to filter captures using both individual and combined filtering, to arrive at the exact information you needĪdvanced techniques like comparison captures and ring buffering to diagnose complex corner cases How to take the best possible captures, maximizing signal and reducing noise How to install Wireshark to both take and view captures Throughout this course, you will open the same captures as the instructor, and use the same techniques he uses to see the same results he gets. Real problems are examined from real network captures, and the techniques used to diagnose these problems are laid bare. Instead, the key skills are trained, with a focus on making sure you understand why this skill is useful, and how the skill is used. No time is wasted on options or features that are not heavily used. This course is specifically designed to walk you through the mindset and methodology an expert uses to diagnose problems with Wireshark. But when you get done with those courses, you still find yourself wondering “How do I actually use this stuff to resolve problems?”
Most courses approach this problem with more overload diving into each menu item and option with detailed explanations. Many engineers, even ones with significant experience, feel powerless and lost when confronted with the sea of data that a network capture can provide. Protocol analysis is a complicated, and often intimidating, subject.
