KevinCrrl/evillimiter-ng ? reverse-engineered prompt

Build me a Linux command line tool in Python for my own local network that can find devices on the network, show them in a simple interactive shell, and let me monitor, analyze, and control their bandwidth. I want to be able to start it by picking a network interface, run a scan for hosts, list what it found, then limit or fully block upload or download speeds for one device or multiple devices, and later free them again.

Please also include helpful commands for adding a host manually, watching selected devices, checking current watch status, importing and exporting scan results to a JSON file, and piping in one off command sequences from the shell. It should work on Linux with Python 3, focus on IPv4 local networks, and have sensible auto detection for gateway, netmask, and interface when possible. Make the terminal experience clear and easy to use, with built in help and a legal warning that this is only for networks I own or am authorized to test. Look up current docs online if you need to.
