Here’s a README draft for your project ferris-tapper:

ferris-tapper

This is a Rust-based network tap tool designed to set up a bridge between two networks, allowing traffic monitoring and analysis. This tool enables users to capture and inspect data flowing through network interfaces, making it ideal for tasks like reverse engineering, debugging, and network analysis.

Features

• Bridge Configuration: Easily set up a bridge between two network interfaces for packet capture and traffic monitoring.
• Traffic Mirroring: Mirror network traffic between interfaces for real-time analysis.
• Qdisc Management: Configure queuing disciplines (qdisc) to manage network traffic and prioritize flows.
  • IPv6: Disable IPv6 on interfaces to focus on IPv4 traffic analysis and prevent IPv6-related issues.
  • Promiscuous: Enable promiscuous mode on network interfaces to capture all traffic, not just traffic directed to the host, so the hosts can communicate with each other.
• Status: Query the current status of network interfaces, including IPv6 settings, promiscuous mode, and qdisc statistics.

Use Cases

• Network Monitoring: Capture and analyze network traffic passing through the configured bridge.
• Reverse Engineering: Inspect network protocols and interactions for reverse engineering purposes on devices or applications.
• Penetration Testing: Use the tool in penetration testing scenarios to monitor and manipulate traffic.
• Debugging: Identify and troubleshoot network issues by capturing packet-level information.

Installation

Ensure you system is a Linux based, this project is designed for Linux systems, leveraging the rtnetlink and sysctl utilities for network configuration.

cargo install ferris-tapper

Usage

Once installed, you can use ferris-tapper to set up, manage, and monitor network configurations.

Note: Is recommended to run the tool with sudo or as root to ensure the necessary permissions for network configuration.

Starting TAP Network Configuration

sudo ferris-tapper start eth0 eth1

This command sets up a bridge between eth0 and eth1, enabling packet capture and analysis.

Stopping TAP Network Configuration

sudo ferris-tapper stop eth0 eth1

Now, this command stops the bridge configuration between eth0 and eth1, reverting the changes made by the tool.

Querying Network Status/Configuration

sudo ferris-tapper status eth0 eth1

This command returns the current network configuration status, including IPv6 settings, qdisc information, and promiscuous mode status for each interface.
