A fast, modular, and ethical local network reconnaissance tool built with Scapy, socket programming, and Nmap. Designed for penetration testing labs, CTF challenges, and authorized network assessments.

• Lightning-fast ARP host discovery using Scapy (Ethernet-layer scanning)
• Custom TCP connect scan on common ports
• Accurate service & version detection with Nmap (-sV)
• Automatic Nmap installation if missing (Linux/macOS support)
• Beautiful terminal UI powered by Rich (tables, panels, colors)
• Multi-format reports: JSON and CSV export
• Ethical usage banner and timestamp

git clone https://github.com/Sudo0xSajal/eth0Scanner.git
cd eth0Scanner
pip install -r requirements.txt

Run the scanner with Python 3:

python3 scanner.py

• Display an ethical usage banner.

• Prompt you to enter the target network (e.g., 192.168.1.0/24 or 172.31.0.0/24).

• Automatically discover live hosts, scan common ports, enumerate services, and generate reports.

• Reports will be saved as scan_report.json and scan_report.csv in the current directory.

python3 scanner.py
Enter Target Network (e.g., 192.168.1.0/24): 172.31.0.0/24
