Description

Remote connectivity is a basic and critical tool for just about any modern technology task, and the SSH - and to a much lesser degree, Telnet - protocols can play large parts in connectivity solutions. However, the complexity of network infrastructure means that establishing and maintaining reliable connections can sometimes be challenging. This course, Protocol Deep Dive: SSH and Telnet, will help you overcome those challenges. You'll start with some SSH connectivity troubleshooting and debugging, as well as care and feeding of the Wireshark network monitoring tool. You'll also get to see the Telnet remote communication protocol, when to use it...and when to avoid it. After completing this course, you'll be able to describe the basic design and function of both SSH and Telnet, tackle some common problems, and have experienced some helpful troubleshooting techniques.
