60 Linux Networking commands and scripts

Recently, I wanted to test network throughput via command line with at least 3 tools. For the life of me, I could not remember iperf. Not being able to remember previously used command line tools is frustrating and something we can all relate to. So I created a go-to-list of network tools for myself. Then, I thought, why not turn this list into a blog post? So I spent another hour or two compiling this ongoing list of Linux Networking Commands and Scripts. I look forward mostly to suggestions, because I know there’s always something missing or new scripts out there to try.
