TCP is a core protocol driving business applications, but is often a blind spot in IT organizations. A thorough understanding of TCP can speed up network and application troubleshooting, empowering engineers to quickly resolve problems.
"The network is slow!" "The application is broken!" "We are being hacked!" Sound familiar? In this course, Foundational TCP Analysis with Wireshark, you will gain the ability to troubleshoot and resolve network problems by harnessing the power of TCP. First, you will learn how TCP connections are established and maintained. Next, you will discover how data is retransmitted during data loss. Finally, you will explore how to quickly find, interpret, and resolve TCP problems using the Wireshark protocol analyzer. When you are finished with this course, you will have the skills and knowledge of the TCP protocol and Wireshark needed to hunt down network problems and resolve them for good.

Course Overview [Autogenerated] Hi, everyone. My name is Chris Greer, and welcome to my course foundational TCP analysis with wire shark. I'm a network analyst, and I've been capturing an interpreting problems with TCP and wire shark for over 15 years. My passion is resolving problems with packets and helping others to learn the art of packet analysis to the TCP Protocol is responsible for supporting and delivering the services and applications that Docker our businesses. But in most IDE organizations, TCP is a bit of a blind spot. Network engineers often get blamed. For Sloan is application disconnects and low throughput when the real underlying culprit can be found with a solid understanding of TCP, I want to show you the fundamentals of this massively important protocol, which will help you to gain comfort, capturing and interpreting it with wire shark. This will help you to be a faster troubleshooter because you'll have the skills with TCP and wire shark to isolate and resolve the root cause of slow performance and other pesky network problems. Some of the major topics that will cover with hands on exercises include mastering the TCP handshake understanding sequence and acknowledgement numbers. What to do about re transmissions and duplicate Acknowledgments and how to interpret TCP window problems. By the end of this course, you will be comfortable with filtering on TCP connections, interpreting TCP errors and identifying the TCP header values, which will lead you to a root cause before beginning the course. You should be familiar with basic networking fundamentals and have a functional understanding of wire shark. I hope you'll join me on this journey to learn how to dig into packets with the course.
