Description

There are what feels like a near infinite number of moving parts in a data network, which means that when things go wrong, they often have cascading consequences that can prevent users from accessing the resources required to do their jobs. In this course, Network Troubleshooting and Tools, you will learn techniques and tools for troubleshooting broken network components. First, you will learn how to use command line utilities like ipconfig, ping, nslookup, Nmap, and netstat. Next, you will learn how to use Wireshark to capture and examine an unencrypted website. Finally, you will learn to use iperf to measure the bandwidth of an internal network and use Nmap to run a port scan on a remote server. By the end of this course, you will know-how to troubleshoot and track down network problems, which are critical skills you must have as an engineer.

Course Overview
Hi everyone. My name is Ross Bagurdes, and welcome to my course, Network Troubleshooting and Tools. I am a network engineer with more than 20 years' experience building enterprise networks and teaching people about them. In the simplest sense, data networking hardware breaks unpredictably often in a way that cascades into much larger issues. Knowing the techniques and tools needed to troubleshoot a network are remarkably important during these outages. In this course, we will look at techniques and tools used to troubleshoot networks, including the command line utilities like ipconfig, ping, and nslookup. We'll look at the Wireshark protocol analyzer. We'll also use NMAP to scan remote servers, as well as learn how to check for common service related issues. By the end of the course, you'll know how to identify a speed and duplex mismatch issue from a bad switchport or bent pins problem on a switch. You'll also be able to use ipconfig and ping to verify that your default-gateway is online. This course builds upon the content in network security fundamentals, and upon completion, you will have the vocabulary, protocol understanding, and troubleshooting tools to be an entry-level network technician. From here, you can move onto more advanced topics in networking like the Cisco Certified Network Associate certification learning path or CCNA learning path. I hope you'll join me on this journey to learn network troubleshooting with the Network Troubleshooting and Tools course, here at Pluralsight.
