Network Scanner - Help
======================

Available Scripts:
-----------------

1. network_scanner.py
   Basic network scanner that discovers devices and gathers info
   Usage: ./network_scanner.py [-c config.json] [-o output.json] [-v]

2. pfsense_scanner.py
   Specialized scanner for pfSense firewalls
   Usage: ./pfsense_scanner.py <ip> [-u user] [-k keyfile] [-o output.json]

3. integrated_scanner.py
   Complete scanner with pfSense integration
   Usage: ./integrated_scanner.py [-c config.json] [-o output.json] [-v] [--generate-svg]

4. svg_generator.py
   Generate SVG diagram from scan results
   Usage: ./svg_generator.py <input.json> [-o output.svg]

Configuration:
-------------
Edit config.json to customize:
- SSH credentials
- Network ranges to scan
- Special device definitions
- Scan timeouts

Examples:
--------
# Quick scan of current network
./network_scanner.py -v

# Full scan with diagram
./integrated_scanner.py --generate-svg

# Scan pfSense
./pfsense_scanner.py 192.168.1.1 -u root -k ~/.ssh/id_rsa

# Generate diagram from existing scan
./svg_generator.py network_scan.json -o my_network.svg
