Raspberry Pi

• Initial user: pi, password: raspberry
• Enable ssh on boot: create file named 'ssh' on boot partition
• First Raspberry Pi, MAC=b8:27:eb:f5:5e:0b
• Second: MAC=b8:27:eb:79:41:20 (hostname: tvu-s003)

To enable ssh login:

DISC=/dev/sdb
mkdir mnt1
mount ${DISC}1 mnt1
touch mnt1/ssh

To enable wireless via wpa_supplicnt.conf:

DISC=/dev/sdb
mkdir mnt2
mount ${DISC}2  mnt2 #mount /dev/sdb2 mnt2
cd mnt2
cat > ./etc/wpa_supplicant/wpa_supplicant.conf <<EOF
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
	ssid="SSID"
	psk="PASSWD"
}

To enable wlan0, as mentioned here in a comment:

DISC=/dev/sdb
mkdir mnt2
mount ${DISC}2  mnt2 #mount /dev/sdb2 mnt2
cd mnt2

cat > etc/network/interfaces <<EOF
auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wpa-ssid "SSID"
wpa-psk "PASSWORD"

# Include files from /etc/network/interfaces.d:
