OSI-first network device diagnosis with vendor commands.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Network Troubleshooting Network device diagnosis using the OSI layer principle. This skill is a **guided diagnostic procedure**, not an output parser: identify the device/platform, gather targeted read-only evidence, and adapt commands to the actual OS/version. Examples are starting points; verify syntax before use. ## When to Use - A device in the `ntn` inventory is unreachable, slow, or behaving oddly. - A user reports "no internet", "can't ping", "link down", "duplex errors". - You need to read the real state before deciding on a configuration change. - You need to distinguish: device down vs path down vs your own SSH session dying. Not for: changing configuration (that is the `network-change-management` skill), adding/removing devices (that is the `ntnroute` skill), or plain Linux servers. ## Core Principles 1. **OSI layers, don't skip.** L1 → L2 → L3 → L4 → L7. Prove the lower layer is healthy before moving up. Exception: a specific symptom (DNS timeout) may go straight to the relevant layer. 2. **Read-only first.** All diagnostic commands are read-only. No `configure`, `set`, or `remove` during diagnosis. Changes = the `network-change-management` skill. …

How to install
mdr add dandi41/ntnroute/network-troubleshooting@sha256:15b1a626d631179bThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
