LoRa Network Server

Project aimed at creating an open-source server capable of processing LoRaWAN and LoRa@FIIT messages. This repository provides a Docker Compose configuration for running a PostgreSQL database, pgAdmin, and a custom server application in isolated containers. It's a convenient way to set up a development or testing environment with these services.

Note: This repository contains a LoRa Network Server with a primary focus on the LoRa@FIIT link-layer protocol.

Prerequisites

Before you begin, make sure you have the following tools and dependencies installed on your system:

• Docker
• Docker Compose

Getting Started

1. Clone this repository to your local machine:

   git clone https://github.com/loraalex/LoNES.git

2. Navigate to the project directory:

   cd LoNES

3. Generate a TLS Certificate (before creating the .env file):

   • Replace ${domain} with your domain name.

   • Run the following commands in a terminal:

     # Install Certbot (Let's Encrypt client) if not already installed
     sudo apt-get update
     sudo apt-get install certbot
     
     # Obtain a TLS certificate (replace placeholders with your actual domain and email)
     sudo certbot certonly --standalone -d ${domain} --non-interactive --agree-tos --email [email protected]

   • The certificate and private key will be saved to /etc/letsencrypt/live/${domain}/.

4. Export the Certificate to a Java Key Store.

   • You can use the import-keystore.sh script located in bin directory
   • You have to edit values inside the script first.
   • Use LONES_KEYSTORE_PASSWORD as a destination password.
   • Use LONES_KEYSTORE as a name of the exported Java Key Store.

   chmod +x ./bin/import-keystore.sh
   ./bin/import-keystore.sh

5. Create a .env file in the project directory with the following environment variables (example values provided):

   DB_NAME=lones
   DB_USER=lones
   DB_PASSWORD=(Choose a strong, complex password)
   DB_PORT=5432
   DB_HOST=postgres
   DB_DRIVER=org.postgresql.Driver
   DB_PROTOCOL=jdbc:postgresql
   
   PGADMIN_EMAIL=[email protected]
   PGADMIN_PASSWORD=(Choose a strong, complex password)
   PGADMIN_PORT=5050
   
   LONES_PORT=8002
   LONES_KEYSTORE=lones.jks
   LONES_KEYSTORE_PASSWORD=(Choose a strong, complex password)
   LONES_PRESHARED_KEY=(e.g. 33 Bytes long key)
   
   LONES_LOGFILE=logs.log

6. Run the install.sh script for the initial setup:

   chmod +x install.sh
   ./install.sh

   • The install.sh script will execute Docker Compose and initialize the database for the first time.

7. Start the services using Docker Compose (for any subsequent builds):

   docker-compose up -d

The services will be running in the background, and you can access them as needed.

Additional Information

• The .env file should be configured with the necessary environment variables for your services. Ensure that you choose strong, complex passwords for database access, pgAdmin, and the keystore.

• The LONES_PRESHARED_KEY should be generated securely and should be of a specific length. Describe the length and generation process according to your security requirements.
