Install a cube

FIXME In 2019 it's outdated !

This procedure explains how to setup an Internet Cube and configure it for Neutrinet. It is based on this document:

Generate the VPN certificates

To use our VPN, you need to follow this registration process to generate the private key and obtain a personnal VPN certificate. There it also a python script. (Both can be touchy)

If, for some reason, you're re-installing a cube and you want to re-use a certificate, you can find them on a running (or dead) cube as user.crt, user.key, ca-server.crt and credentials in /etc/openvpn/keys.


This is the strict minimum you need:

  • a computer (preferably running a Linux/Unix/BSD system) to perform the install
  • a A20-OLinuXino-LIME board
  • a microSD card where the Cube operating system (Yunohost/Debian) will be stored
  • a MOD-WIFI-R5370-ANT WiFi Antenna
  • a 5V DC power adapter
  • a Neutrinet VPN account (Note : for the moment (until correction), the FQDN of the confirmation link ( need to be replace by

You can find details about the components and buy them here


You'll also need:

  • An Internet connection to download the Yunohost image.
  • An ethernet cable to connect the Cube to your home router (e.g: your Proximus BBox)

Install Yunohost on the SD Card

In order to install the latest version of Yunohost on the SD card, we'll use a simple script that does the hard work for you.

Download the script

Open a terminal, then:

$ mkdir ~/internet-cube-install
$ cd ~/internet-cube-install
$ wget
$ chmod 0755

Run the script

First remove the SD card from your computer if present.

In your terminal, run (add the -2 argument if you use a Lime2 and not a Lime1 and -e if you wan a fully encrypted file system) :

$ ./ [-e] [-2]

And follow the on screen instructions. It will: - detect your SD card - download the latest Yunohost image - verify its integrity - install the image on your SD card (all data on the SD card will be lost)

Remove the SD card from your computer when it's done.

Start your Cube

Prepare it

  • Make sure the Cube is not connected to a power source (e.g: the power cable should be unplugged)
  • Insert the WiFi antenna into the USB port of the Cube's board
  • Insert the SD card into your Cube
  • Connect your Cube to an ethernet cable that is connected to your home router (e.g: your Proximus BBox)
  • Make sure your computer is connected (via WiFi or ethernet) to your home router too (you will connect to your Cube via the local network)

Boot it

  • Connect the power cable to the Cube to start it
  • Wait a couple of minutes to let the Cube start and connect to the network

Find it on the network

In order to connect to your Cube, you need to find its IP address on your local network.

In your terminal, run:

$ ./ -l

The output should look like this:

Internet Cubes found on the network:

  1. YunoHost Admin:
     SSH Access:        ssh root@
     HyperCube Debug:

In this example, the IP address of your Cube on the local network is:

If the script cannot find your cube, try again a couple of minutes later.

Connect to your Cube via SSH

To connect to your Cube as root, in your terminal, run:

$ ssh root@

(Please replace with the IP address of your Cube found in the previous step) The root password of your Cube is: olinux

You'll be asked to change it. Please choose a strong password and do not loose it.

Configure your Cube for use with Neutrinet

Now that you're connected to your Cube via SSH, you will download the configuration script and run it:

root@olinux:~# wget
root@olinux:~# chmod 0755
root@olinux:~# ./

And follow the on screen instructions. Important: at some point during the installation, the script will prompt your for an “Administration password”. This password is: neutrinet

It will: - ask you for:

  1. a Main domain name. If you choose, you'll access your cube via
  2. a Username, used to connect to the user interface and access your apps
  3. your Firstname/Lastname, used to send emails
  4. an Email. It must contain the domain previously entered as second part, e.g:
  5. VPN client certificate. This is the content of the client.crt file you download.
  6. VPN client key. This is the content of the client.key file you download.
  7. CA server certificate. This is the content of the ca.crt file you download.
  8. VPN username/password. Can be found in the auth file you downloaded.
  9. IPv6 delegated prefix. If you don't have one, leave it blank (only necessary if you want to use IPv6)
  10. WiFi AP SSID. This is the name of the WiFi network created by your Cube, as it will appear in the available WiFi list of your computer.
  11. The Administration password. This password is: neutrinet

- update the system - finish the Yunohost configuration - install the following Yunohost apps:

  1. vpnclient: to connect to the Neutrinet VPN
  2. hotspot: to create a WiFi network
  3. doctorcube: to help fix the Cube in some situations
  4. neutrinet_ynh: to help fix the outdated certificate issue

Change all passwords

Those passwords have been set to 'neutrinet' (without quotes) during the install process.
