Doomsday Box

In today's world you can never be too safe with your data. So why not make your own digital safe house for it?

StepOne: Raspbian

Just like you need walls to your safe house you need a operating system to keep everything contained in your virtual safehouse

Grab Raspbian at this link

https://downloads.raspberrypi.org/raspbian_lite_latest

You will also need a program to put the OS on your micro SD card

https://www.balena.io/etcher/

Once you have those things downloaded open your file manager

The Raspbian and extract it, next open up etcher and select the extract Raspbian and flash it to the micro SD

StepTwo: The setup

create a file in your micro SD card called "wpa_supplicant.conf"

inside this file put

ctrl_interface=DIR=/var/run/wpa_supplicant 
GROUP=netdevnetwork={    
ssid="YOUR_SSID"   
psk="YOUR_WIFI_PASSWORD"    
key_mgmt=WPA-PSK}

Next make a file called "ssh" with no extension\

Put the micro SD card in the raspberry pi and power on the pi and wait a few minutes

connect to your pi do a scan of your WiFi, I'm using a app on my phone called "Net Analyzer"

Find the IP of your pi and ssh into "pi@<REPLACE WITH PI's IP>"

ssh pi@192.168.0.59

the password should be "raspberry"

now run the following code

passwd

change your default password for security reasons

sudo passwd

change roots password too

sudo apt-get update && sudo apt-get upgrade

update and configure the PI

StepThree: Soracom

go to soracom.io

• Make a account
• add your sim
• configure payment info

Put the sim card into the modem and plug it into the raspberry pi

Open the SSH tab again and run

sudo apt-get install nmcli

gets the software to make the sim work

sudo curl -O https://soracom-files.s3.amazonaws.com/starterkit/setup.sh

Grabs the configs

sudo chmod +x setup.sh

gives the configs permission to do their thing

sudo ./setup.sh

makes the configs do their thing

congrats you just added your PI to the Soracom network!

StepFour: Amazon web services and VPC connections

this is a rather difficult task I recommend following the tutorial here

StepFive: The box

Secure all the components in the box using hot glue If you are using a solar panel secure it to the top and drill a hole in and run the wire through and make the hole watertight make sure everything is plugged in and working.

StepSix: File transfers

when your box is out in the wild you will need to send files to it so it can protect them

For this we will be using SFTP

I recommend using Win SCP for sending files

https://winscp.net/eng/index.php

open up a SFTP to your AWS EC2 instance you created in step four and send the files you want safe to preferably in /home/<user>/transfer

now ssh into your EC2 instance

ssh -i "xxx-dev01.pem" ec2-user@ec2-52-196-xxx-xxx.ap-northeast-1.compute.amazonaws.com

make sure to replace the info in the command with your info

now open the connection to the PI

sudo sftp pi@<assigned vpc ip for pi>

now you can transfer files to your virtual safe house here is a handy cheat sheet for file transfers in command line SFTP communications

Congratulations you are now the owner of your own virtual safe house!
