DHCP Client Simulator (Raw Sockets, No Scapy)

This project simulates multiple DHCP clients in parallel using raw sockets, without relying on Scapy or external libraries. It performs the full DHCP handshake (DISCOVER → OFFER → REQUEST → ACK) and gracefully releases leases on exit.

---

✨ Features

• ⚙️ Configurable number of clients and concurrency
• 🚀 Pure Python, no third-party dependencies
• 🔁 Full DHCP exchange per client
• 📉 Summary statistics after run
• 🧹 Sends DHCPRELEASE on Ctrl+C or normal exit
• ✅ Works well on Linux or macOS with elevated privileges

---

📦 Requirements

• Python 3.7+
• Root privileges (to bind to privileged ports and send broadcasts)
• Linux or macOS (tested on both)

---

🛠️ Usage

# Standalone usage
sudo python3 client/dhcp_simulator.py

# Or with Docker
docker-compose up

# ==== CONFIG ====
# Edit client/dhcp_simulator.py to configure:
TOTAL_CLIENTS = 50         # Number of DHCP clients to simulate
MAX_CONCURRENT = 10        # Maximum concurrent clients
LEASE_DURATION = 30        # Hold leases for N seconds before releasing
INTERFACE = 'eth0'         # Interface (eth0 in Docker, may be different on host)
