How to set up a Raspberry Pi
Raw
headless-rpi.md

Install Rasbian

Most of the time I use a headless Raspberry Pi which I want to access via ssh. These are the steps to do that.

  1. Download Rasbian
  2. Install the downloaded file on a SD card
  • Find the disk number of the SD card with diskutil list
  • Unmount the disk with diskutil unmountDisk /dev/disk<number>
  • Copy data on the SD card with sudo dd bs=1m if=<img-file> of=/dev/rdisk<number> conv=sync
  1. Configure ssh and WiFi settings as described on stackoverflow
  • Enable ssh by creating an empty file at /Volumes/boot/ssh
  • Configure WiFi by providing a file at /Volumes/boot/wpa_supplicant.conf with the following content
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
ssid="<ssid>"
psk="<pwd>"
}
  1. Check if the Raspberry Pi is connected to the WiFi with ping raspberrypi.local
  2. ssh onto it with ssh pi@rasbperrypi.local (password is raspberry)

If WiFi is not needed at all, you can disable it with iwconfig wlan0 txpower off. Use on to turn it on again.
