Basic Network Troubleshooting Using Wireshark Training Course

This course is tailored for network engineers and technicians possessing foundational Wireshark proficiency who seek to execute advanced network traffic analysis. Participants will acquire skills to diagnose performance, application, and security challenges—including VoIP, DNS, database systems, and network attacks—by leveraging command-line tools, advanced filtering techniques, and forensic methodologies. The training emphasizes practical application through real-world enterprise network scenarios, suitable for government infrastructure management.

Wireshark serves as a free, open-source packet analyzer utilized for the systematic troubleshooting of network operational issues. Network packet analysis is a critical technique employed to observe, in real time, the raw data transmitted and received via network interfaces. This capability is essential for diagnosing network configuration variances and application-level performance anomalies for government operations.

This instructor-led live training, available in both onsite and remote formats, equips participants with advanced methodologies for troubleshooting the functionality and performance of network infrastructure and associated applications. This course extends the curriculum of “Network Troubleshooting with Wireshark,” which primarily addresses common HTTP applications. The current session expands to encompass protocols and connection mediums such as Wi-Fi, HTTPS, SMTP, and various enterprise-grade applications.

Upon completion of this training, participants will be prepared to:

• Isolate and resolve network security vulnerabilities using the Wireshark command-line interface for government environments
• Troubleshoot applications utilizing protocols beyond HTTP, including HTTPS, FTP, mail services, and DNS
• Diagnose network connection impediments in enterprise applications such as databases and RPC services
• Resolve connectivity issues in media-intensive applications, including VoIP and streaming services
• Apply network forensics techniques to trace and detect potential security incidents

Target Audience

• Network engineers
• Network and computer technicians

Course Structure

• Combination of instructional lectures, collaborative discussions, and intensive hands-on practice exercises

Network packet analysis is a methodological approach for observing, in real time, the raw data transmitted and received via network interfaces. This technique is critical for diagnosing configuration errors and application-level anomalies. Wireshark serves as a free, open-source analytical tool widely utilized for resolving such network challenges.

In this instructor-led, live training module, personnel will acquire the skills necessary to employ Wireshark for diagnosing both the structural integrity and performance metrics of networked applications. The curriculum covers fundamental principles of network diagnostics and provides practical techniques for capturing and evaluating TCP/IP request and response traffic between clients and server infrastructure.

Upon completion of this training, participants will be proficient in:

• Evaluating network functionality and performance across diverse operational environments
• Assessing the adequacy of server application performance
• Isolating primary contributors to network degradation
• Diagnosing and resolving prevalent performance impediments within TCP/IP communications

Target Audience

• Network engineers
• Network and computer technicians

Instructional Format

• Combination of lectures, discussions, and extensive hands-on practical exercises

Administrative Note

• Contact the administration to arrange customized training modules for this course for government entities.

This hands-on course provides a practical introduction to packet network analysis and troubleshooting for government using Wireshark. Participants learn how to capture, filter, and analyze network traffic across all layers of the ISO/OSI model and the TCP/IP protocol suite to identify communication issues, performance bottlenecks, and protocol-level anomalies. Through practical exercises based on real network traces, the course develops essential troubleshooting skills for modern IP networks.
