RazzMaster

Find and set up new Raspberry Pis on your network.

RazzMaster can do the following tasks:

  • scan the local network for probable Raspberry Pis
  • blink the LED on the Pi
  • report hardware and software version of the Pi
  • install packages through apt-get and node
  • setup wifi

Installation

npm install -g razzmaster
razzmaster version

Scan for Raspberry Pis on your network

razzmaster scan

This will scan for probable Raspberry Pis on your network using MAC addresses for common Raspberry Pi ethernet and wifi dongles. It will print a list of every MAC address it finds and whether it is likely to be a Raspberry Pi or not. Sometimes it may not find the Pi right away. If you don't see it, just run the scan again a few more times.

Blink your Raspberry Pi

Just to make sure you are really connecting to the pi you think you are, make the green LED blink like this:

razzmaster blink --host 192.168.1.23 --username pi --password raspberry

Press ctrl-C to stop it.

Note that if you do not specify a username and password Razzmaster will use the default Raspbian ones of pi/raspberry. If you haven't changed the settings then you can leave these options off like this:

razzmaster blink --host 192.168.1.23

Get Info

To get the hardware and software versions of your Raspberry Pi

razzmaster info --host 192.168.1.18

This will print the model and OS info. On my Raspberry Pi 2 running Raspbian Jesse I get:

Raspberry Pi 2 Model B Rev 1.1
PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
NAME="Raspbian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Linux raspberrypi 4.1.7-v7+ #817 SMP PREEMPT Sat Sep 19 15:32:00 BST 2015 armv7l GNU/Linux 

Configure the Raspberry Pi:

razzmaster install --config config.json --host 192.168.1.23 --username pi --password foo

This command will ssh into the Raspberry Pi with the host ip address, username, and password supplied. It will use config.json to decide what to install.

Your config.json file will look like this:

{
    "packages":[
        "git",
        "curl",
        "bluez",
        "bluez-hcidump",
        "nodejs"
    ],
    "git":[
        "https://github.com/joshmarinacci/amx.git"
    ]
}

The packages array is a list of Debian packages to install. The nodejs package is treated special. It will install from nodesource.org instead of the regular repos.

The git array is a list of git repos to fetch.

Setup Wifi

Add a 'wifi' section like this:

{
   "wifi": {
       "ssid":"myrouter",
       "password":"mypassword"
   }
}

Todo

  • -- done -- set the wifi info
  • set the hostname
  • change the default users password
  • configure node for proper npm -g support
  • set extra/custom services to start on demand
  • set x in kiosk mode with chromium
  • disable starting x

A full headless install

Yes, it is possible to start with a blank RaspberryPi and get it running on the network with your desired configuration without using a directly connected screen. You'll have to flash a Raspbian image directly to the flashcard first, since NOOBS requires a screen to use, but then you can do the rest with RazzMaster.

first, download the raspbian image via torrent or direct download. this is a giant zip file which regular MacOSX unzip can't handle. If you unzip it from the command line you'll get an error about

need PK compat. v4.5 (can do v2.1)

So install p7zip via brew and unzip with that.

brew install p7zip
7za x your_raspian_image_file.img

Then write the image to your SD card as described in the standard docs here

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

now put the SD card in your Pi and boot it. Since it doesn't have any wifi access yet, you'll need to boot it with wired ethernet connected to your other computer or a router. Make sure the ethernet port is live before you boot the Pi. ex: if you are plugging the pi directly into a port on your Mac then you'll need to turn on internet sharing so that the Pi can get an IP address when it boots.

let it boot for about 3 minutes (pi2) since it's going to load a full desktop environment. then run node find.
