Introduction

It's kind of a pain to find your Raspberry Pi's ip address when you connect it to a new network. I created this tool to quickly find my raspberry pi.

This is version 2. Version 1 is written in Perl, and everything is in clear text. This time, I decided to learn AES encryption.

Description

You need Python on your machine and on the Pi.

There are two programs needed.

rasPyFinderd: A little daemon that runs on the Pi.
rasPyFinder: A Program that runs in a linux shell (might work on windows too... untested).

First, pifinder broadcasts an encrypted message on the network. Upon reveiving that message, the daemon responds with it's hostname and ip addresses.

To install the daemon on the Pi (Requires root access or sudo):

Navigate to the directory where you want to put the script (ex: cd /usr/local/bin)
git clone https://github.com/michaudm/rasPyFinder.git
cd rasPyFinder
Edit rasPyFinderd.service with your favorite editor (vi, nano, ...)
Change ExecStart= to add the path to your rasPyFinder (ex: ExecStart=/usr/local/bin)
Save your file (nano-> Ctrl+X, vi-> :wq)
sudo cp rasPyFinder.service /etc/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable rasPyFinder.service
The daemon should start automatically after the next reboot.

If you want to start it immediatly: sudo service rasPyFinder start

Run with ./rasPyFinder in a linux shell

All Comments in the scripts are in french... sorry.
