Network packet analysis is a technique used to view, in real time, the raw data sent and received over a network interface. This is useful for troubleshooting network configuration and network application problems. Wireshark is a free open source packet analyzer used for troubleshooting such network issues.
In this instructor-led, live training, participants will learn how to use Wireshark to troubleshoot the functionality of a network as well as the performance of differente networked applications. Participants will learn network troubleshooting principles and practice techniques for capturing and analyzing TCP/IP request and response traffic between different clients and the servers.
By the end of this training, participants will be able to:
Analyze network functionality and performance in various environments under different conditions
Determine whether instances of different server applications are performing acceptably
Identify the primary sources of network performance problems
Identify and troubleshoot the most common causes of performance problems in TCP/IP communications
Audience
Network engineers
Network and computer technicians
Format of the Course
Part lecture, part discussion, exercises and heavy hands-on practice
