Ben's notes

Note: this is an unencrypted install!

• Download the latest image
• Verify the download:

  $ sha256sum kali-2017.01-usbarmory.img.xz 
  2b2b1d42c255fbb34e6ea24d35dc33639f6b52f05d9378a3e3ccaea793d824ee  kali-2017.01-usbarmory.img.xz

• Write the image to the SDcard:

  # lsblk      # /dev/sdc is my SDcard device
  # xzcat kali-2017.01-usbarmory.img.xz | dd of=/dev/sdc bs=1M status=progress
  

• 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:

  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

• Log in with user root/toor:

  ssh root@10.0.0.1

• Configure forwarding:

  echo "net.ipv4.conf.eno1.forwarding = 1" >> /etc/sysctl.d/50-forwarding.conf
  sysctl -p

• 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.

  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

• Mount the SDcard and add the following modules to /etc/modules:

  ledtrig_heartbeat  # comment this line if you don't want that intense blinking LED.
  ci_hdrc_imx
  #g_mass_storage
  g_ether

• Connect the SCcard to the host machine.
• Modify partition:

  # parted /dev/mmcblk0
  print
  
  rm 1
  mkpart primary ext2 5243kB 100%
  
  print
  quit

• Reboot:

  reboot

• Login and resize filesystem:

  resize2fs /dev/mmcblk0p1
