DavidsonRafaelK/evillimiter ? reverse-engineered prompt

Build me a Linux command line tool that can scan my local network, list the devices it finds, and let me slow down or block specific devices without needing admin access on the target machine.

It should work from a normal terminal, auto detect the network interface, gateway, and subnet when possible, and also let me pass them in manually if needed. I want commands to scan the network, show hosts with IDs, limit bandwidth by device, block traffic, and optionally add delays or packet loss for testing. It should support watching selected hosts so it can keep enforcing the limit if they reconnect.

Please include a simple config file so I can save defaults like interface, scan range, and log file, plus a way to run it without colors. Also make sure it can flush any network rules it adds, and show clear errors if required system tools are missing. If you need to, look up current docs online for Linux networking commands and Python packaging.
