Troubleshooting faulty network connectivity, part 2: Essential network commands

In my previous article describing the troubleshooting steps for faulty TCP/IP connections, I mentioned several commands such as ping, traceroute, and ipconfig that could assist you in pinpointing problematic network components. These commands and several others like them are commonly referred to as TCP/IP utilities because they are tools that let you perform diagnostics and queries on the network which you are examining.

To compliment Part 1 of this two-part series, Part 2 is a reference list of the TCP/IP utilities which will describe the intended uses and options for each. These tools natively run in command line interface (CLI) environments (or in Linux and Unix, “shell prompts”), but as several entries in this blog show, there are a great many graphical utilities available that let you use the TCP/IP utilities (and view their output) in graphical format. In this article, however, I will stick with the default CLI usage and functionality.

Remember: the best way to learn and understand these tools is to practice with them. Also bear in mind that knowledge of these commands is often essential during ethical hacking efforts and for networking certification exams.
