Quick setup

Set manual ip to usb0: 10.0.0.2, no routing, no DNS, via NotworkManager or:

/sbin/ip link set usb0 up
/sbin/ip addr add 10.0.0.2/24 dev usb0

Give connectivity to USB armory

/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.1/32 -o wlan0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

Connect

ssh usbarmory@10.0.0.1 # pwd usbarmory

Or via ShellInABox: https://10.0.0.1:4200/

Quick setup time (in case ntpdate couldn't catch up at boot)

ssh usbarmory sudo date --set $(date +@%s)

Free the LED

ssh usbarmory@10.0.0.1 sudo sed -i '/^ledtrig_heartbeat/d' /etc/modules

Quick backup of the most important things (~9Mb)

ssh -n usbarmory@10.0.0.1 'sudo tar -cpf - /etc /root /home /var' |gzip > backup-$(date "+%Y%m%d-%H%M%S").tgz
