Python-Based IoT Gateway for Linux
Budget: $30 – $250 USD
Abstract
Python-Based Internet Connection Bridging for Linux
This project presents the development of a Python application designed to establish a seamless bridge between primary Ethernet or Wi-Fi and secondary cellular modem connections on Debian, Ubuntu, and Raspbian Linux systems. By dynamically managing network interfaces and routing tables, the application aims to provide uninterrupted internet connectivity by automatically switching between the primary and secondary connections based on predefined criteria. The project leverages Python's versatility and cross-platform compatibility to offer a flexible and efficient solution for users.
Statement of Work (SOW)
Project Title: Python-Based Internet Connection Bridging for Linux
1. Project Overview
The objective of this project is to develop a Python-based application for Debian, Ubuntu, and Raspbian Linux systems that seamlessly bridges primary Ethernet or Wi-Fi and secondary cellular modem connections. The application will prioritize the primary connection while maintaining an active secondary connection as a backup. Upon detection of primary connection failure, the application will automatically switch to the cellular connection and revert back to the primary connection once it is restored. Additionally, the application will include a self-starting mechanism and a web interface for configuration management.
2. Deliverables
• Python application: A fully functional Python script capable of bridging Ethernet/Wi-Fi and cellular connections on Debian, Ubuntu, and Raspbian Linux systems.
• Configuration management: A web-based interface for modifying and persisting configuration settings such as cellular APN, connection priorities, and failover criteria.
• Documentation: Comprehensive user documentation, including installation, configuration, and troubleshooting guides.
3. Project Scope
• Network interface management: Dynamically configure and manage network interfaces for both primary and secondary connections.
• Routing table manipulation: Modify routing tables to direct traffic appropriately based on connection status.
• Connection monitoring: Continuously monitor the status of both primary and secondary connections.
• Failover mechanism: Automatically switch between connections based on predefined criteria (e.g., ping loss, connection speed).
• Self-starting capability: Ensure the application starts automatically upon system boot.
• Web interface: Develop a user-friendly web interface for configuration management.
• Error handling: Implement robust error handling and logging mechanisms.
4. Project Timeline
• A detailed project timeline will be established upon project initiation, taking into account project complexity, resource availability, and client requirements.
5. Project Roles and Responsibilities
• Development Team: Responsible for the design, development, testing, and documentation of the Python application and web interface.
• Client: Responsible for providing system access, testing the application, and providing feedback.
6. Acceptance Criteria
The project will be considered complete and accepted upon successful completion of the following:
• The Python application functions as specified, seamlessly bridging primary and secondary connections.
• The web interface allows for efficient configuration management.
• Comprehensive documentation is provided.
• The application has been thoroughly tested and meets client acceptance criteria.
7. Project Management
• Project management will follow an Agile methodology to ensure flexibility and responsiveness to changes.
• Regular progress reports and status updates will be provided to the client.
Note: This SOW provides a general outline and may require further refinement based on specific project requirements and constraints.
