Speedtest for Hackers

If you want to do an ongoing speedtest with graphs for up- and download, forget about the web-based tools like speedtest.net and fast.com – 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 lafo@dublin.zhaw.ch "cat /dev/urandom" > /dev/null


cat /dev/urandom| ssh lafo@dublin.zhaw.ch "cat > /dev/null"

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

0verkill (howto enjoy work properly – the geeky way)

If you ever lacked an idea on how to spend your time at work properly, here’s a fun thing to try: 0verkill – a multiplayer 2D ASCII art shooter.Hell yeah, an ASCII art shooter, you heard right! To hell with those flashy commercials claiming to be proper games!

If you’re on a Debian box (as you should), you can install it from the commandline
$ aptitude install overkill

If you’re less lucky, you can also go to the author’s homepage, download and build it yourself. The package will feature the game itself, a dedicated server and a level-editor. Plenty of room for a great many gaming sessions!

1. There were more players, but I didn’t managage to get my glorifying screenshot soon enough.
2. Beware of server lag. I played it in a screen session on a Linux VPS. I got a load average of up to 19.48, 7.16, 3.00
