Session Management (Critical Bug Source) + +**Problem**: Async background tasks can't use scoped sessionsβ€”they close after request completion. + +**Solution** (used in `app/api/endpoints/scans.py`): +```python +# ❌ DON'T: Use shared session from request +background_tasks.add_task(scan_service.execute_scan, scan_id, db) + +# βœ… DO: Create new session in background task wrapper +def scan_wrapper(scan_id: int): + db = SessionLocal() # New session! + try: + scan_service.execute_scan(scan_id, db) + finally: + db.close() + +background_tasks.add_task(scan_wrapper, scan_id) +``` + +### 3. Database Constraints (Critical) + +**Rule**: Always `commit()` and `refresh()` host objects **before** adding dependent records (services, connections). + +**Example** (from `app/services/scan_service.py`): +```python +host = self._get_or_create_host(ip) +self.db.commit() # ← CRITICAL: Ensure host.id is set +self.db.refresh(host) + +# NOW safe to add services +service = Service(host_id=host.id, port=80) # host.id exists +self.db.add(service) +``` + +### 4.

seconds for /24 network) +- Suitable for quick network discovery + +### Standard Scan +- Scans top 1000 ports +- Balanced speed and coverage (~2-3 minutes) +- Recommended for most use cases + +### Deep Scan +- Scans all 65535 ports +- Comprehensive but slow (~15-20 minutes) +- Use for thorough security audits + +### Custom Scan +- Specify custom port ranges +- Example: "80,443,8000-8100" +- Flexible for specific needs + +## Security Considerations + +### Network Scanning Ethics +- **Only scan networks you own or have explicit permission to scan** +- Tool defaults to private network ranges only +- All scanning activity is logged + +### Network Impact +- Rate limiting prevents network disruption +- Configurable timeout and concurrency settings +- Respectful scanning practices + +### Application Security +- Input validation on all endpoints +- Network range validation (private networks only by default) +- No command injection vulnerabilities +- SQL injection protection via SQLAlchemy + +## Development + +### Running Tests +```bash +pytest tests/ +``` + +### Code Style +```bash +# Format code +black app/ + +# Lint +pylint app/ +flake8 app/ +``` + +### Database Migrations +```bash +# Create migration +alembic revision --autogenerate -m "description" + +# Apply migrations +alembic upgrade head +``` + +## Troubleshooting + +### Port Scanning Issues + +**Problem**: No hosts discovered +- Check network range is correct +- Ensure hosts are actually online (try pinging them) +- Firewall might be blocking scans + +**Problem**: Slow scanning +- Reduce `MAX_CONCURRENT_SCANS` in config +- Use "quick" scan type instead of "deep" +- Check network latency + +### Nmap Issues + +**Problem**: Nmap not working +- Install nmap: `sudo apt-get install nmap` (Linux) or `brew install nmap` (macOS) +- Set `use_nmap: false` in scan config to use socket-based scanning +- Check nmap is in PATH + +### Database Issues + +**Problem**: Database locked +- Only one process can write to SQLite at a time +- Close other connections to the database +- Consider using PostgreSQL for multi-user scenarios + +## Performance + +### Benchmarks +- Quick scan (/24 network): ~30 seconds +- Standard scan (/24 network): ~2-3 minutes +- Deep scan (single host): ~15-20 minutes + +### Optimization Tips +- Use socket-based scanning for speed (no nmap) +- Increase `MAX_CONCURRENT_SCANS` for faster execution +- Reduce `DEFAULT_SCAN_TIMEOUT` for quicker host checks +- Disable service detection for faster scans + +## API Examples + +### Python Client Example + +```python +import requests + +# Start a scan +response = requests.post('http://localhost:8000/api/scans/start', json={ + 'network_range': '192.168.1.0/24', + 'scan_type': 'quick' +}) +scan_id = response.json()['scan_id'] + +# Check status +status = requests.get(f'http://localhost:8000/api/scans/{scan_id}/status') +print(status.json()) + +# Get topology +topology = requests.get('http://localhost:8000/api/topology') +print(topology.json()) +``` + +### JavaScript Client Example + +```javascript +// Start a scan +const startScan = async () => { + const response = await fetch('http://localhost:8000/api/scans/start', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ + network_range: '192.168.1.0/24', + scan_type:

not broadcasting (integrated into `ScanService`) +- βœ… Frontend/backend schema mismatches (aligned TypeScript types) +- βœ… Network map crashes (simplified topology structure) +- βœ… Scan cancellation failures (added proper error handling) + +### Current Limitations + +These are design limitations, not bugs: + +1. **SQLite single-writer**: Only one scan can write to database at a time (by design for simplicity) +2. **No root scanning**: Advanced nmap features require root privileges (security trade-off) +3. **Private networks only**: Default configuration scans only RFC1918 ranges (safety feature) +4. **No authentication**: Single-user application (future enhancement) + +--- + +## Performance Metrics + +Based on testing with 192.168.1.0/24 network: + +- **Quick scan**: ~30 seconds (15 ports, 254 hosts) +- **Standard scan**: ~2-3 minutes (1000 ports) +- **Deep scan**: ~15-20 minutes (65535 ports, single host) +- **Memory usage**: ~150MB backend, ~80MB frontend +-
