Wireshark Počítačové Kurzy

Transport of baseband audio and video streams across IP networks using multicast signalling protocols is becoming increasingly used in broadcast networks.

This 3 day course/workshop covers the theory and practice of implementing these protocols within IP and Ethernet networks. The practical element of the course will use Cisco L3 switches and the multicast streamers and receivers will use the cross -platform VLC application. It is not necessary to have any expertise in the Cisco command line as the configuration of the devices can be instructor-led if required. However the course is intended to have at least 50% practical content and can be customised or even lengthened (to examine the protocols in more detail) if run as a single company event.

The purpose of the course is to provide the participant with basic knowledge of the Wireshark protocol analyzer. The course focuses on deep understanding of the tool, as the basics for using it for network troubleshooting. The course starts with packet capturing, capture and display filters, statistical features and the basics of the expert system. By the end of the course the participant will be able to perform basic troubleshooting in small to medium size networks. The course is based on theory, class exercise and labs.

This course is a continuation of the "Basic Network Troubleshooting Using Wireshark" course, and comes to provide the participants with advanced capabilities for network troubleshooting. The course provides an in-depth knowledge of network behaviour and problems, along with the capabilities to isolate and solve security and advanced applications problems. The course is based on theory, class exercise and labs.

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

In this instructor-led, live training (onsite or remote), participants will learn advanced techniques for troubleshooting the functionality and performance of a network and its applications. This course is an extension of "Network Troubleshooting with Wireshark", which focuses primarily on common HTTP applications. In this training, we consider 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 solve network security issues using the Wireshark CLI
- Troubleshoot applications that use protocols beyond HTTP, including HTTPS, FTP, mail, DNS, etc.
- Troubleshoot network connection problems in enterprise applications such as databases, RPC, etc.
- Troubleshoot connection problems in media applications such as VoIP and streaming
- Use network forensics to trace and detect security issues
