Connect

Via Ethernet

To setup an connection to the rae via Ethernet give your interface the right IP. It has to be 10.10.0.10. For Linux based Systems it is:

sudo ifconfig IF 10.10.0.10 netmask 255.255.255.0

IF is for example eth0. After setting the correct IP Adress you can connect via SSH. The Standard-user is romzn and the password is raeisgreat. Rae hosts an little DNS Server which enables you to reach the System via rae.local.

ssh [e-mail]

Via Wifi

The rae opens an access point with the name "rae" with the password "raeisawesome". After successfully connected to the hotspot you can connect via ssh in the same manner like before:

ssh [e-mail]

Via VSCODE SSH Extension

Install the following extension and setup an ssh connection with the rae.local domain and the user romzn https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh

Enable Internet through Host Computer

To route the Internet from your Host to the rae several steps are necessary. The following internet configuration is for the Ubuntu linux distribution:

First of all you have to activate Port forwarding on your Host and not on the RAE

sudo sysctl -w net.ipv4.ip_forward=1

after that you have to set some entries into your iptables to forward the packages correctly

sudo iptables -t nat -A POSTROUTING -s 10.7.0.1/24 -j MASQUERADE
sudo iptables -t nat -A POSTROUTING -s 10.10.0.1/24 -j MASQUERADE

To save them permanently onto your file System do:

sudo apt install iptables-persistent
sudo iptables-save  > /etc/iptables/rules.v4

Now you can test with ping www.google.de if the connections works.

Add a new user

Add a new user and add them to the groups dialout and tty

sudo adduser otto
sudo usermod -a -G tty otto
sudo usermod -a -G dialout otto

Activate the access point in ac-mode

The prebuilt image already covers the configuration If you want to checkout how its done look here
