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

Power up the Pi

Next time you boot up the Pi you should see your wifi card light blinking.

Try running an nmap scan for port 22 before and after the pi is plugged in, from another computer on the same network:

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.
