About this project

A powerful CLI tool designed for diagnosing Wi-Fi, DNS, and TCP performance issues on Linux systems. This tool offers safety-first features, including dry-run simulations and rollback capabilities, alongside comprehensive diagnostics and modular optimization options, making it ideal for developers and system administrators.

A powerful command-line utility designed to diagnose, benchmark, and optimize networking performance on Linux systems. The Network Debug Tool addresses common issues with Wi-Fi, DNS, and TCP configurations while providing safety features for system administrators, developers, and power users who require effective network optimization.

Key Features

Comprehensive Network Diagnosis: Detects issues related to Wi-Fi, DNS, and TCP configurations automatically.
Safety-First Design: Offers dry-run simulations, timestamped backups, and rollback capabilities to ensure safety during optimizations.
Interactive & Automated Modes: Provides options for guided optimizations or fully automated fixes.
Cross-Distribution Compatibility: Supports various Linux distributions, including Ubuntu, Pop!_OS, Arch, Fedora, and Alpine.
Detailed Reporting: Generates professional reports in JSON and Markdown formats, along with before-and-after benchmarking.
Modular Architecture: Features a plugin-based system with six built-in optimization modules to enhance network performance.

Usage Example

Run a comprehensive diagnosis to identify network issues and potential optimizations:

./network_debug.py --diagnose

For frequent users, quick commands are readily available for specific tasks, such as checking system dependencies:

./network_debug.py --check-deps

The tool also enables safe optimizations with a dry-run option before applying any changes:

sudo ./network_debug.py --auto-fix --dry-run
# Apply changes
sudo ./network_debug.py --auto-fix

Optimization Rules

The tool includes six built-in optimization modules that streamline network performance adjustments:

Rule	Category	Description
TCP	System	Optimizes TCP buffer settings and congestion control.
Wi-Fi	Wireless	Manages power settings, band selection, and signal analysis.
DNS	Network	Enhances DNS server performance and caching configurations.
Driver	Hardware	Identifies and resolves common driver-related issues.
Interface	Hardware	Adjusts hardware settings for network interfaces.
VPN	Network	Detects VPN usage and suggests performance enhancements.

Safety Features

The tool prioritizes user safety with:

Root Privilege Enforcement: Ensures that system-level changes are authorized.
Dry-Run Simulations: Allows users to preview changes before implementation.
Rollback Mechanisms: Automatically reverts changes when verification fails, ensuring system integrity.

With this tool, improvements in network performance can be substantial, including reduced latency and increased throughput. For those seeking efficient and reliable network optimization, the Network Debug Tool stands out as an essential resource.
