Wipe SD Cards

Wipe SD cards and install raspbian

Mount SD Cards

Mount the SD cards as a local filesystem on a Linux box

Now, if you want to modify the file /foo/bar, you can edit the file on the SD card at /media/ubuntu/rootfs/foo/bar

=Enable SSH

Touch a file named ssh in the boot sector of the SD card to enable the service to start on boot:

touch /media/ubuntu/boot/ssh

Wifi

Set up wpa supplicant config file for your local wifi network

https://charlesreid1.com/wiki/Ubuntu/Bespin#Configure_WPA_Supplicant

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="YOURWIFINETWORK"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk="YOURWIFIPASSWORD"
}

Network Interfaces

Next set up the WPA supplicant service to automatically start for our wifi device

Update the contents of your network interfaces file to look like this:

/etc/network/interfaces

source-directory /etc/network/interfaces.d

allow-hotplug lo
iface lo inet loopback

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

Reboot

Next time you reboot you should see your wifi card light blinking. Try running an nmap scan for port 22 before and after the pi is plugged in:

nmap -p22 192.168.0.0/24 > nmap-before

# plug in the pi, wait a few minutes

nmap -p22 192.168.0.0/24 > nmap-after

assuming your home wifi is 192.168.0.0/24.
