We bought this board with a [grant from EthKipu](https://collective.flashbots.net/t/funding-a-rebel-node-in-the-south-a-journal/3071#of-june-2023-8). ![IMG_20250314_182701](https://collective.flashbots.net/uploads/default/original/2X/f/f58a5e4f2707fee800a79f1a422219780344dc9a.jpeg) ![IMG_20250314_182725](https://collective.flashbots.net/uploads/default/original/2X/2/26068e926098eacbc000e0738acd170d6af59b72.jpeg) > **[Radxa ROCK 5B](https://radxa.com/products/rock5/5b/)** > > 8K Single Board Computer with Quad Display ---

> Tested on march 14th, 2025 # Installation Download the Radxa OS image: ```auto wget https://github.com/radxa-build/rock-5b/releases/download/rsdk-b5/rock-5b_bookworm_kde_b5.output.img.xz ``` Get an sdcard, an adapter, and connect it to the machine. Copy the image to the sdcard: ```auto $ unxz rock-5b_bookworm_kde_b5.output.img.xz $ sudo dd if=rock-5b_bookworm_kde_b5.output.img of= bs=16M status=progress oflag=sync ``` Move the sdcard to the board. Connect it to the power and to an HDMI monitor. Login with user `radxa` and password `radxa`. Open a terminal. Enable ssh: ```auto sudo systemctl enable --now ssh ``` Now I can move it to the rack and login with ssh. Login with user `rock` and password `rock`. Rename the radxa user: ```auto $ sudo usermod --login agami radxa $ exit ``` Login with user `agami`, password `radxa`. Change the password: ```auto $ passwd ``` Delete the `rock` user: ```auto $ sudo deluser --remove-home rock ``` Install software for administration: ```auto $ sudo apt update $ sudo apt install emacs-nox byobu ``` Enable ssh public key authentication: ```auto $ mkdir --mode 700 ~/.ssh ``` Add my user public key to `~/.ssh/authorized_keys`. Adjust the permission of this file. ```auto $ chmod 600 .ssh/authorized_keys ``` Disable ssh password autentication: Edit the file `/etc/ssh/sshd_config`, uncommenting and setting: ```auto PasswordAuthentication no ``` ```auto $ sudo systemctl reload sshd ``` Change the hostname: ```auto $ sudo hostnamectl set-hostname tabechaka-06 ``` Also edit the file `/etc/hosts` to replace `raspberrypi` with `tabechaka-06`. Reboot: ```auto $ sudo systemctl reboot ``` ---
