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.
