Prepare Raspberry for Remote Maintenance

Context

When Rapid.Space provider needs to do some maintenance on the server and they want the help of Rapid.Space people, it is better to have a Raspberry Pi device where Rapid.Space team can always connect to. This raspberry pi will connect to the internet using the hotspot of mobile phone. Rapid.Space team will connect to this raspberry pi using re6st.

How to setup the raspberry pi

download Debian 10 based raspbian image : https://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2019-09-30/2019-09-26-raspbian-buster-lite.zip
extract the archive with 7z e 2019-09-26-raspbian-buster-lite.zip
flash it on sdcard with sudo bash -c 'pv < 2019-09-26-raspbian-buster-lite.img > /dev/mmcblk1' (if you don't have pv, you can run sudo bash -c 'cat 2019-09-26-raspbian-buster-lite.img > /dev/mmcblk1') WARNING make sure to write in the correct disk
insert it in Raspberry Pi 3 model B and boot (default user is "pi" and password is "raspberry")
use raspi-config (see https://www.raspberrypi.org/documentation/configuration/raspi-config.md) to change keyboard in French (or in other language of your keyboard) and locale to en-US.utf8 and password of "pi" user to "nexedi"
edit /etc/network/interfaces to have the following content (this will configure IP on the ethernet and wifi):

auto eth0
iface eth0 inet static
address 192.168.46.2
netmask 24

# setup of Wifi connection, make sure to use the parameter from your phone
auto wlan0
iface wlan0 inet dhcp
wpa-ssid yourwifiname
wpa-psk yourpassword

install Freefib re6st (run the comands as root)

wget https://deploy.erp5.net/gnet/re6st # in China, you can use "wget https://deploy.erp5.cn/gnet/re6st"

# make sure to have requested a token (see vifib-HowTo.Request.Freefib.Re6st.Token)
FORCE=yes bash re6st

# you will need to insert your token and chose if you want router advertisement

install openssh-server

sudo apt install openssh-server

sudo systemctl start ssh

sudo systemctl enable ssh

setup the Rapid.Space team ssh key in pi account (run the command below as pi user)

cat >> ~/.ssh/authorized_keys << EOF

give the IPv6 to the Rapid.Space team (run "ip -6 address" command and give the output to Rapid.Space team) so they can test if they can access

Optional: use this raspberry Pi to install the OCP machine's OS

You can now follow rapidspace-HowTo.Partner.Server.OS.Installation if you want to use this Raspberry device to install the OS on your OCP machines.
