Get the image

Get the latest image and save it to disk:

# Desktop version
wget -O ~/raspbian.zip https://downloads.raspberrypi.org/raspbian_latest

# Lite version
wget -O ~/raspbian_lite.zip https://downloads.raspberrypi.org/raspbian_lite_latest

Burn the image

Unzip the image:

unzip ~/raspbian*.zip

Burn the image to disk:

sudo dd bs=1m if=~/path_of_your_image.img of=/dev/rdiskn conv=sync

Mount the image and enable ssh and wifi configuration to be used from /boot

Mount the disk and navigate to the mounted /boot partition:

cd /Volumes/boot

Enable ssh on boot:

touch ssh

Enable wifi:

export SSID="somewifi"
export WIFIPASS="assword"

cat <<EOF >> wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
    ssid="$SSID"
    psk="$WIFIPASS"
}
EOF

Unmount the image

Unmount SD Card:

sudo umount -f /Volumes/boot

OR on mac:

diskutil unmount /Volumes/boot/

Now shove the sdcard up the back of the raspberry pi, attach power and wait for the pi to connect to wifi and make and ssh connection to raspberrypi.local:

ssh [email protected] -o PreferredAuthentications=password

Install when ssh access

User configuration

Create the user we'll use for SSH access:

sudo su 
adduser flip
echo 'flip ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers.d/010_pi-nopasswd

Configure ssh access

mkdir /home/flip/.ssh

cat <<EOF  >> /home/flip/.ssh/authorized_keys
