Linux Networking and Troubleshooting (English)
Follow this course and learn how IP networks work, diagnose Linux networking and capture, filter and analyze traffic using capture files and specialized tools.
Time to examine where network traffic wants to go, where it's actually going, or what it's running into.
In this course, we'll discuss how an IP network works, how applications connect, and how to configure and diagnose on Linux. We will tackle connection setup problems hands-on by systematically routing network traffic. You will learn to capture network traffic, filter it and analyze where it comes from and where it goes. You can then store this traffic in a capture file to analyze later with specialized tools. This will give you deeper insight into exactly what is happening in a network data packet and what can go wrong along the way.
This course covers the following topics:
#Network theory: the TCP/IP stack, protocols, and structure
- Linux network configuration
- Tools for testing the network and network services
- Packet capture with tcpdump and analysis with Wireshark
- Firewall
- Logfiles
