Kali Linux is not one of the officially supported distros by the ZeroTier installer script, so if you just try to use it you will get an error message along the lines of:

Kali Linux is based on Debian testing, so we can just “trick” the ZeroTier install script into thinking it’s Debian and it installs just fine:

On occasion you need to listen for incoming connections and interact with the data being sent by the client. Most simple way might be with netcat (12345 is the port number to listen to):

(-l for listen, -v for verbose, this will let you know once…

I like seeing CPU load on my boxes, so pretty much all of them have some sort of CPU load gadget enabled on startup. I noticed every time I have to configure this on a Kali box I’m struggling to remember the package names for what I have to install, so having done it today I decided to do a write this so I don’t have to struggle next time.

It’s fairly simple, really:

  • Install gnome-shell-extension-system-monitor package (doesn’t require addition of PPA compared to indicator-multiload):
  • Open Tweaks (either find it in the menu under Applications -> Usual Applications -> System tools -> Preferences, or press the Windows key and type tweaks to search for it).
  • Select Extensions, enable System-monitor, click on the gear and set your preferences.
  • Enjoy.
