pi-ip

What Is This?

pi-ip is a global node module for installing on your Raspberry Pi, so that when it starts up it will report it's IP address in a cloud hosted Firebase database of your choosing.

Additionally, this module supports being installed on multiple Raspberry Pi's, all with differently configured names. All of the Pi IP addresses will be available in the same Firebase database.

Setup

Install & Configure pi-ip

1. Login to your raspberry pi

2. Install pi-ip: npm install -g pi-ip

3. Configure pi-ip: pi-ip config

4. Test it out: pi-ip

   You should see something like the following

   Network Interfaces:
   { lo: 
      [ { address: '127.0.0.1',
          netmask: '255.0.0.0',
          family: 'IPv4',
          mac: '00:00:00:00:00:00',
          internal: true } ],
     eth0: 
      [ { address: '192.168.1.124',
          netmask: '255.255.255.0',
          family: 'IPv4',
          mac: 'b8:27:eb:2f:a2:19',
          internal: false } ] }
   IP eth0: 192.168.1.124
   IP wlan0: disconnected

Setup to Run on Startup

1. Create an init.d run script /etc/init.d/pi-ip.sh with the following contents:

   #!/bin/bash
   export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/node/bin"
   pi-ip

2. Make sure the pi-ip.sh script is executable: sudo chmod ugoa+rx /etc/init.d/pi-ip.sh

3. Set the script to run on startup: sudo update-rc.d pi-ip.sh defaults

4. Reboot your pi: sudo reboot

5. Watch your Firebase database for updates! The database will have a node named Pi, with a node for each Pi within it. The JSON would look something like this:

   {
     "Pi" : {
       "my-pi" : {
         "eth0" : "192.168.1.124",
         "utc" : "2015-05-11 07:21:45",
         "wlan0" : "192.168.1.126"
       }
     }
   }

Future

Wireless Network Configuration stored in Firebase, and setup on the PI upon bootup using a wired connection, then auto reboot.
