Quick Start

# Clone and enter
git clone https://github.com/alexladwong/network-analyzer-pro.git
cd network-analyzer-pro

# Create virtual environment and install
python3 -m venv .venv
source .venv/bin/activate
pip install psutil ping3

# Optional: enable advanced features
pip install scapy

# Run
python3 main.py

For full functionality (packet capture, ARP scanning), run with root:

sudo python3 main.py

Architecture
