Raspberry Pi setup

Guide to setup a Raspberry PI device.

Prepare the SD card

• Flash a SD card with RPi OS: src

diskutil

• Install macports
• Add the credentials to the boot image, src
• old: src, notes, WPA, wifi pass

touch /Volumes/bootfs/ssh
# Setup username and password (just openssl on Linux)
brew install openssl
/opt/homebrew/opt/openssl/bin/openssl passwd -6 | sed -e 's/^/USERNAME:/;' > /Volumes/bootfs/openconf
# Hash your WiFi password
# sudo apt -y install wpa_passphrase
sudo port install wpa_passphrase
wpa_passphrase "cool-house5" # then enter password
# Fill in the password hash
vim /Volumes/bootfs/wpa_supplicant.conf


# TODO: replace with custom.toml

• Add WPA2/3 support: ref
  • vim /Volumes/bootfs/cmdline.txt
  • Append brcmfmac.feature_disable=0x82000
• Kernel configs
  • vim /Volumes/bootfs/config.txt
• Eject SD card and plug into Pi
• Power on Pi (LED status codes)

Configure the OS

• Log in

ssh-keygen -R raspberrypi.local
ssh pi@raspberrypi.local
ip addr

• Basic Debian Linux setup
• Disable GUI, autologin (src), expand fs

sudo raspi-config
sudo reboot

# on Mac
ssh-keygen -R raspberrypi.local
ssh jdoe@SUBDOMAIN.janedoe.com

Networking

• Record the MAC address, ip addr
• In pfSense, create a static DHCP lease

• Go to Services >> DHCP Server >> LAN >> DHCP Static Mappings

• Add a DNS record

• Update unbound.conf
• Go to Services >> DNS Resolver >> Custom options, paste in config
