6	Logging — handlers, rotation
7-8	pytest — unit testing, mocking
9-10	Capstone — Network Config Audit Tool

Capstone — Network Config Audit Tool

Offline and online network configuration audit tool for PS engineers.

Features

• Offline audit against config file snapshots (no device access needed)
• Online audit via live PyEZ polling (concurrent, 7 devices)
• BGP export policy consistency check
• CE interface hygiene check
• Markdown report generation
• FastAPI REST interface
• Git-committed findings for audit trail
• 44 pytest tests

Usage

# Offline audit
python3 -m audit_tool.audit_runner

# API
uvicorn audit_tool.api.main:app --port 8001

Environment variables

cp .env.example .env
# edit .env with your credentials

⚠️ Note on credentials

Weekly exercise scripts (week1_.py through week6_.py) contain hardcoded lab credentials for a private learning environment. Replace with environment variables before use in production. The audit tool (audit_tool/) uses environment variables via config.py.
