Quick headless setup for the Raspberry PI

Setup a headless image before you dd it on your SD card. Only needed step is to enable ssh, the rest is convenience, if you must use wifi for example. Works for pi zero, pi3, pi2... Perform as root.

Enable SSH

Add a file named ssh in the boot partition of the image :

mount -o loop,offset=$((8192 * 512)) /storage/2017-01-11-raspbian-jessie-lite.img /media/ Mount boot partition from image

echo > /media/ssh Enable ssh

Remove automatic resize/filling of the sd card on 1st boot

Useful if you want to setup a multi boot.

nano /media/cmdline.txt Assuming image is still mounted from previous step

Remove the stuff after quiet and it looks like that :

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet

umount /media/

Extend size of the partition

Add 1go of space to your image, you can repeat command to add more or edit count= :

dd if=/dev/zero bs=1M count=1024 > /storage/2017-01-11-raspbian-jessie-lite.img

Run parted parted /storage/2017-01-11-raspbian-jessie-lite.img

Then type resizepart 2 Enter 100% Enter quit Enter

Check with fdisk -lu /storage/2017-01-11-raspbian-jessie-lite.img

Change keyboard layout

mount -o loop,offset=$((137216 * 512)) /storage/2017-01-11-raspbian-jessie-lite.img /media/

nano /media/etc/default/keyboard

Edit XKBLAYOUT="gb" to XKBLAYOUT="fr" or anything else

Change default password

makepasswd --clearfrom=- --crypt-md5 << YOURPASSWD Encrypt your password

nano /media/etc/shadow

Remove this line pi:$6$k0vFWRoG$bEBdFcFBWw2fLEA.5LsVKOtLWdWSkZMnEikqOG4jHCneRrWEBnEt6.ROe60ggdA7DbdU.l2ZO35WFvi3q6Ays/:17130:0:99999:7:::

Replace with pi:YOURMD5PASSWD:17130:0:99999:7:::

Enable wireless connectivity

Particularly useful on the rpi0, since it has no rj45.

nano /media/etc/network/interfaces Then replace :

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

With

auto wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

nano /media/etc/wpa_supplicant/wpa_supplicant.conf Then add :

For WEP

network={
ssid="NAMEOFYOURAP"
wep_key0=PASSPHRASE
key_mgmt=NONE
wep_tx_keyidx=0
priority=2
}

For WPA

network={
ssid="NAMEOFYOURAP"
psk="PASSPHRASE"
priority=1
}

For open network

network={
ssid="NAMEOFYOURAP"
key_mgmt=NONE
priority=0
}

You can add as much as you want and sort them with priority=
