Hpperr/HYDRA- ? reverse-engineered prompt

Build me a simple Python command line tool for authorized network security testing in a lab. I want to be able to run it with sudo, choose a network interface, scan the local network to find devices, and optionally point it at one specific target IP for a controlled test. Keep it straightforward and usable from one main script, with clear command line options for interface, scan mode, and target mode, plus readable output so I can tell what it’s doing.

Please make it feel like a lightweight security framework aimed at mobile or wireless network testing, but don’t overcomplicate it. Add basic validation, safe error messages, and a short README with example commands like scanning on eth0 and targeting a single IP. If something isn’t clear, check current Python docs or common CLI patterns online, and keep the whole thing clearly framed for legal, permission based testing only.
