Basic Network Troubleshooting Using Wireshark Training Course

This course is tailored for network engineers and technicians with foundational Wireshark experience who seek to conduct advanced network traffic analysis. Participants will gain the skills necessary to diagnose performance, application, and security issues, including those related to VoIP, DNS, databases, and network attacks, by utilizing command-line tools, advanced filters, and forensic techniques. The training emphasizes practical application through real-world enterprise network scenarios, ensuring that attendees are well-prepared to address complex challenges in their professional environments for government and other public sector roles.

Wireshark is a free, open-source packet analyzer utilized for troubleshooting network issues. Network packet analysis involves examining, in real-time, the raw data transmitted and received over a network interface. This technique is essential for diagnosing network configuration and application problems. In this instructor-led, live training (onsite or remote), participants will learn advanced techniques for troubleshooting the functionality and performance of networks and their applications. Building on the foundational course "Network Troubleshooting with Wireshark," which primarily focuses on common HTTP applications, this training expands to cover a broader range of protocols and connection mediums such as Wi-Fi, HTTPS, SMTP, enterprise applications, and more. By the end of this training, participants will be able to: - Isolate and resolve network security issues using the Wireshark Command Line Interface (CLI). - Troubleshoot applications that use protocols beyond HTTP, including HTTPS, FTP, mail, DNS, and others. - Diagnose network connection problems in enterprise applications such as databases and Remote Procedure Call (RPC) services. - Address connection issues in media applications like Voice over Internet Protocol (VoIP) and streaming services. - Utilize network forensics to trace and detect security vulnerabilities. **Audience** - Network engineers - Network and computer technicians **Format of the Course for Government** - Part lecture, part discussion, with exercises and extensive hands-on practice.

Network packet analysis is a method used to monitor, in real time, the raw data transmitted and received over a network interface. This technique is essential for diagnosing network configuration issues and problems with network applications. Wireshark, a free and open-source packet analyzer, is widely utilized for troubleshooting such network challenges.

In this instructor-led, live training, participants will learn how to use Wireshark to assess the functionality and performance of a network, as well as the performance of various networked applications. Participants will gain an understanding of network troubleshooting principles and practice techniques for capturing and analyzing TCP/IP request and response traffic between different clients and servers.

By the end of this training, participants will be able to:

• Evaluate network functionality and performance in diverse environments under various conditions
• Determine if instances of different server applications are operating within acceptable parameters
• Identify primary sources of network performance issues
• Diagnose and address the most common causes of performance problems in TCP/IP communications

Audience
