🌐 myLG - Network Diagnostics & Troubleshooting Toolkit

A comprehensive open-source network diagnostic utility that combines multiple network probes into one powerful tool

📋 Overview

myLG is an advanced network diagnostics and troubleshooting toolkit written in Go that consolidates various network monitoring and analysis functions into a single, efficient command-line interface. Designed for network administrators, DevOps engineers, and security professionals, myLG provides real-time insights into network performance, connectivity, and infrastructure health.

✨ Key Features

🔍 Network Diagnostics

• Local ping and real-time traceroute with visual feedback
• HTTP/HTTPS ping (GET, POST, HEAD methods) for web service monitoring
• Packet analyzer for TCP/IP and other network protocols
• Port scanning capabilities for security assessment
• Network LAN Discovery to identify devices on local networks

🌍 Global Network Intelligence

• 200+ countries DNS Lookup information
• Popular looking glasses integration (Telia, Level3, NTT, Cogent, KPN)
• BGP route visualization through major network providers
• RIPE database queries (ASN, IP/CIDR information)
• PeeringDB integration for peering policy and network information

📊 Management & Monitoring

• Quick NMS (Network Management System) with SNMP support
• Internet Speed Test for bandwidth analysis
• Web dashboard for visual monitoring and analytics
• Real-time network statistics and performance metrics

💻 Advanced CLI Features

• Interactive shell with vi and emacs mode support
• CLI auto-complete and command history
• Configurable options for customization
• Direct shell access to all diagnostic commands
• Colorized output for enhanced readability

🚀 Quick Start

Prerequisites

• Go 1.12 or higher
• libpcap-dev (for packet capture functionality)

🏗️ Architecture

myLG is built with a modular architecture consisting of:

• CLI Interface (cli/) - Interactive command-line interface
• Network Probes (icmp/, http/) - Ping, traceroute, HTTP monitoring
• Looking Glasses (lg/) - Integration with major network providers
• Packet Analysis (packet/) - Network packet capture and analysis
• Services (services/) - Web dashboard and HTTP API
• Network Discovery (disc/) - LAN device discovery
• Speed Testing (speedtest/) - Bandwidth measurement
