Intent
Script network configuration so setup is consistent across runs and devices.
When to use
- Network interfaces are inconsistent across hardware.
- Secure remote access is required for data extraction.
- Connection setup must be repeatable and verifiable.
- Operators need clear recovery steps.
Core mechanics
- Bind configuration to stable hardware identifiers.
- Automate setup and teardown with scripts or units.
- Validate connectivity before proceeding.
- Log applied configuration and changes.
Implementation checklist
- Collect stable hardware identifiers or hostnames.
- Define network configuration templates.
- Automate setup and teardown sequences.
- Verify routing, DNS, and connectivity.
- Record applied configuration for audit.
- Provide a rollback or recovery script.
Failure modes and mitigations
- Interface renames -> enforce udev or matching rules.
- Tunnel failures -> retry with backoff and alerts.
- Misrouted traffic -> validate routes and DNS.
- Permission errors -> document sudo requirements.
Observability and validation
- Connection status and uptime checks.
- Tunnel duration and failure counts.
- Network error logs.
- Latency or ping metrics.
Artifacts
- Network configuration files.
- Udev rules or interface bindings.
- Connection log samples.
