Observe. Explain.
Change. Check.

LinkMethod is a network engineering and documentation project focused on how connections behave in practice.

Start with the whole request

Follow the path from the device to the application. A healthy interface, an open port and a useful response are distinct observations. Keep their meaning precise.

Preserve the evidence

Record versions, conditions and the previous configuration. Useful documentation makes the result repeatable and gives future work a reliable starting point.

Keep the next step proportionate

Choose a change that addresses the measured problem. Validate it, observe a fresh connection, and leave a clear account of what has and has not been verified.
