usbarmory-setup

I order my usbarmory device from crowdsupply to Europe, and after more than one month and paying customs duties, the Armory finally arrived :-)

My purpose is to use the Armory a my password manager with KeePass, and also INTERLOCK (file encryption front end).

1. Preparing your own microSD card

• 1. check microSD-compatibility
• 2. choose one of the available images for usbarmory.
• 3. burn the image into microSD card

I choose a Samsung microSD and a pre-compiled release of Debian stretch image available here.

2. Connect to usbarmory

Option 1 - serial

The usbarmory serial port can be connected to via a USB to TTL cable; the breakout header can connect as described in gpio page.

I solder a header in usbarmory and use pins 1,5,6 to connect 'usb to ttl' adapter with silicon CP210x chipset and specific drivers. To connect in macOS use the next command:

screen /dev/tty.SLAB_USBtoUART 115200

Option 2 - ssh connection

In this image usbarmory-debian-base_image usbarmory cames with predefined ipv4 address 10.0.0.1, so set you ip address to 10.0.0.2 and connect to your usbarmory.

Now you can log in with

ssh 10.0.0.1 -l usbarmory

3. Prepare KeePass

Setup is done with Ansible

• setup ssh
• install keepass2, etckeeper and common utilities

4. INTERLOCK

work in progress

Notes

WE need the RNDIS/Ethernet Gadget interface in the macOS Network Preferences.

To share macOS internet access with the usbarmory device, you can:

option 1

sudo ./scripts/connection_share.sh

option 2

• set usbamory ip to 192.168.2.X/24 and gateway 192.168.2.1
• in macOS set ip address of RNDIS/Ethernet Gadget interface to 192.168.2.1
• finally set Enable Internet Sharing to ON in System Preferences
