Common Errors & Solutions

pip install fails

Use a virtual environment: python3 -m venv venv && source venv/bin/activate

Too many requests / banned by sources

Increase delays in config/setting.py or use fewer sources

# Full scan python3 oneforall.py --target example.com run # Quick scan (fewer sources) python3 oneforall.py --target example.com --fmt json run # Output to specific directory python3 oneforall.py --target example.com --path ./results run
