findmypi

Send the local ip address of your Raspberry Pi via email

Background

When you connect your Raspberry Pi to a network with DHCP, it is sometimes hard to find out the IP of the Pi. Ways to solve this include:

• Connect a screen/keyboard and look up via 'ifconfig'
• Look at the DHCP IP assignment table of the router
• Set a static IP at the Pi
• Tunnel the Pi through another computer
• Try out all possible IPs
• Have the Pi tell you it's IP ...

This script here is the last solution. On boot it will look if the Pi has an IP and send it to you via mail. Boom, you are in!

The repository lives at http://github.com/freenerd/findmypi

Installation

Clone the repository

cd ~
git clone git://github.com/freenerd/findmypi.git
cd findmypi

Copy and change the settings file

cp settings_example.py settings.py
nano settings.py

You can enter your own smtp server. The default is using Gmail.

Please note that your email password will be in the settings in plain text. If your RaspberryPi gets stolen, the attacker might gain access to your whole email account. The safest way is to create a dedicated email account. If you use Gmail, you can also use an 'application specific password'.

Once this is done, check if it works locally:

python findmypi.py

# check your email inbox for the email

You will probably want to have this script be executed on startup

sudo nano /etc/rc.local

# add to the bottom just before 'exit 0'
python /home/pi/findmypi/findmypi.py &

Restart your Pi and wait for the email
