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.

There is a lot here to look over. I will have to check into this more when I have time. I used to do this a lot. Loved working with commands and scripts and trying different things out.
Great list. I’ve used smokeping in my early years with Linux to monitor my wan interface. It was great but I recently moved to uptimeKuma to monitor my internet and other docker apps.
I also used snort via pfsense but man, things were always being blocked, so I only placed it in monitoring mode
