Gitin
IT inventory: keep track of devices, networks and cables in a database
Have an independent desktop app for your Linux laptop, to manually keep track of assets in your IT environment, keep inventory of occupied IP addresses, devices, NIC's, networks. Cables that run from one point to another (connected to NIC's in devices) and as such cross certain rooms (or not), unused cables (available or lost?)
Keep everything in a MySQL compatible database, so that you have full access to your data in any case.
GitinCLI (Gambas interpreted) for cases where no full desktop...
