Here I Am

Description

Here I Am is a Phoenix application that monitors devices connecting to your local network and plays a text-to-speech message using espeak when a new device is detected. The application uses arp-scan to identify devices on the network.

Prerequisites

Erlang and Elixir

In this project, these are managed by asdf. You will need to install 'https://github.com/asdf-vm/asdf, ['https://github.com/asdf-vm/asdf-erlang](ASDF Erlang), and ['https://github.com/asdf-vm/asdf-elixir](ASDF Elixir). Be sure to read on what the Erlang / Elixir ASDF prerequisites are before installing the plugins.

Alternatively, you can install erlang/elixir without a version manager but that won't be covered here.

Installing `espeak`

Install espeak on your system:

# On Debian/Ubuntu-based systems
sudo apt-get install espeak

# Fedora/RHEL
sudo dnf install espeak

Installing `arp-scan`

Install arp-scan on your system:

# On Debian/Ubuntu-based systems
sudo apt-get install arp-scan

# Fedora/RHEL
sudo dnf install arp-scan

Configuring `sudo` for `arp-scan`

To allow arp-scan to run without a password, edit the sudoers file:

sudo visudo

Add the following line to allow your user to run arp-scan without a password (replace yourusername with your actual username):

yourusername ALL=(ALL) NOPASSWD: /usr/sbin/arp-scan

Your arp-scan installation may not be in /usr/sbin/arp-scan. Please run whereis arp-scan to find the correct path for the above config.

Setup

To start your Phoenix server:

Run mix setup to install and setup dependencies
Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

Ready to run in production? Please check the deployment guides.
