My home network has gotten... excessive. I need something more than a spreadsheet to keep track of all my wires, routers, switches and devices. Does anyone know of a good network topology software? I'm looking for something that's cheap or free that will scan my network, detect all the devices and routers, and put them on a topology map for me. There are some really nice $1,000's tools that do this, and there's OpenNMS but that seems pretty elaborate for what I need. There's freemium SpiceWorks but I'm worried about privacy (assuming once I install their apps they are allowed to pipe into my home network and do as they please).
