I will not update this blog anymore, but I did continue writing on two other pages.

As a Zen monk, I continue to write on and as a programmer I will post on

Thank you for coming here and may you have a good time.

Speedtest for Hackers

August 7th, 2016 — 08:20 am

If you want to do an ongoing speedtest with graphs for up- and download, forget about the web-based tools like and – those are nice if you are on mobile. Yet, when you are on a *nix machine, there’s better tooling in your Shell.

Speedtest Download

First, fire up a Terminal and start `nload` to view network traffic. If you are on macOS, you can also use the graphical tool ‘activity monitor`.

Then, in a second Terminal, start a permanent upload or download with the following commands:


ssh "cat /dev/urandom" > /dev/null


cat /dev/urandom| ssh "cat > /dev/null"

Note that depending on your `ssh` configuration, you might need to disable compression on the client or server side.
