=====Kali on USB Armory=====

{{::usbarmory.jpg?direct&600|}}

**Note:** this is an unencrypted install!
====Install Kali on the SDcard====
  * Download the [[https://www.offensive-security.com/kali-linux-arm-images/|latest image]]
  * Verify the download:<code>$ sha256sum kali-2017.01-usbarmory.img.xz 
2b2b1d42c255fbb34e6ea24d35dc33639f6b52f05d9378a3e3ccaea793d824ee  kali-2017.01-usbarmory.img.xz</code>
  * Write the image to the SDcard:<code># lsblk      # /dev/sdc is my SDcard device
# xzcat kali-2017.01-usbarmory.img.xz | dd of=/dev/sdc bs=1M status=progress

</code>
  * Plug in the device. When the USB Armory has booted up, you should have a new USB network interface on your host machine, for example ''enp0s20f0u1i1''.
  * Configure the USB network interface:<code>
nmcli con mod 'Wired connection 1' connection.id usbarmory
nmcli con mod usbarmory ipv4.addresses 10.0.0.2/24
nmcli con mod usbarmory ipv4.method manual
nmcli con up usbarmory</code>
  * Log in with user root/toor:<code>ssh root@10.0.0.1</code>

====Forward traffic from USB Armory====
  * Configure forwarding:<code>
echo "net.ipv4.conf.eno1.forwarding = 1" >> /etc/sysctl.d/50-forwarding.conf
sysctl -p</code>
  * Add direct rules to firewalld. The ''%%--%%permanent'' option to keep these rules across restarts. Interface ''eno1'' is the interface connected to the rest of the network.<code>
firewall-cmd --permanent --direct --add-rule ipv4 nat POSTROUTING 0 -o eno1 -j MASQUERADE
firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i enp0s20f0u1 -o eno1 -j ACCEPT
firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD 0 -i eno1 -o enp0s20f0u1 -m state --state RELATED,ESTABLISHED -j ACCEPT
firewall-cmd --reload
</code>

====Fix: does not boot after apt-get update====
  * Mount the SDcard and add the following modules to ''/etc/modules'':<code>ledtrig_heartbeat  # comment this line if you don't want that intense blinking LED.
ci_hdrc_imx
#g_mass_storage
g_ether
</code>
====Expand root filesystem====
  * Connect the SCcard to the host machine.
  * Modify partition:<code># parted /dev/mmcblk0
print

rm 1
mkpart primary ext2 5243kB 100%

print
quit</code>
  * Reboot:<code>reboot</code>
  * Login and resize filesystem:<code>resize2fs /dev/mmcblk0p1</code>
