This is the official github repository for the NAV Coin Stake Box. This repository is the source code behind the raspberry pi image which runs the navcoin daemon and a PHP based web wallet.

You can download the raspberry pi image from our website

http://www.navcoin.org/downloads

Below are some basic security configurations which you might want to implement when setting up your NavPi. The NavPi will work immediately if you simply burn the img to the SD card, plug it into your network and turn it on.

• Format the SD card choosing FAT (MSDOS) format and GUID Partition Map Schema.
• Download and install Etcher: https://etcher.io
• Follow Etchers instructions on how to burn the Nav Pi img to the SD Card.

These should be straight forward, just follow the official documentation:

https://www.raspberrypi.org/documentation/installation/installing-images

Because we ship the image with some default settings, we do recommend taking the following precautions.

SSH is disabled for security purposes, so any configuration you want to do must be done directly on the device.

• Write img to SD Card.
• Insert SD Cart into Raspberry Pi.
• Plug in Screen, Keyboard & Mouse.
• Power on Raspberry Pi.

It is recommended to use Ethernet as WiFi can be very slow to sync, but if you must use WiFi you can set it up via the graphical user interface on the device.

• Boot to the Raspberry Pi GUI Operating System.
• Right click on the network icon in the top right task bar.
• Add your WiFi configuration.

• Boot to the Raspberry Pi GUI Operating System.
• Open Terminal.
• In terminal type sudo leafpad /etc/apache2/sites-available/navpi.conf and press enter.
• Add a # symbol to the beginning of the line Require all granted making it #Require all granted.
• Remove the # symbol from the beginning of the line #Require ip XXX.XXX.XXX.XXX and replace XXX.XXX.XXX.XXX with the IP Address of the device you wish to access the web interface of the NavPi from (eg. 192.168.1.10).
• Save and close the file.
• In terminal type sudo service apache2 reload and press enter.

• Boot to the Raspberry Pi GUI Operating System.
• Open Terminal.
• In terminal type passwd and press enter.
• Enter navpi101 as the current password.
• Enter your new password.
• Confirm your new password.
• Write down your new password.

• Boot to the Raspberry Pi GUI Operating System.
• Open Terminal.
• In terminal type ifconfig and press enter.
• Find your inet addr (eg. 192.168.1.99).
• Using the computer on your network which you've granted IP access to, open your web browser (Firefox, Chrome, Internet Explorer, Safari).
• In the address bar of your internet browser type in the inet address discovered by ifconfig on the raspberry pi.
• Log into the NavPi Web Interface using the default password nav.

• Log into the Web Interface of the NavPi.
• Click on the Control menu item
• In the Server section, click the Change UI Password button.
• Type in your new password.
• Confirm your new password.
• Write down your new password.

• Log into the Web Interface of the NavPi.
• Click on the Control menu item.
• In the Security section, type your desired password into the text field next to the Encrypt Wallet button.
• Press enter, or click the Encrypt Wallet button.
• Write down your new password.

You can back up your wallet using the GUI but the file will be written to the folder /home/pi/Desktop/backup which can be found on the default users desktop.

You will need to plug in a screen, keyboard and mouse, then save the generated wallet.dat file to a USB thumb drive.

Or you can back up the wallet.dat file manually:

• Boot to the Raspberry Pi GUI Operating System.
• Open Terminal.
• In terminal type sudo cp /home/pi/.navcoin4/wallet.dat /home/pi/Desktop/wallet.dat and press enter.
• Type in the default sudo password navpi101 or your own password if you have changed it.
• You should now see wallet.dat appear on the desktop.
• Save this file to another location like a USB drive.
• Make multiple backups to protect against data corruption.

• Create a .dmg of the whole SD Card using disk utility.
• Convert the dmg to an img from terminal: hdiutil convert foo.dmg -format UDTO -o bar.img

This .img file can now be burned to a new SD Card using Etcher.
