Wait a minute, fwknopd is cool and all, it’s still proprietary.

Why hasn’t anyone implemented port knocking with something as simple and ubiquitous as SSH public key authentication (or even password if desired) for port knocking? It could even fire-off RPC signals to other servers from a single bastion..

@kayos@twtxt.net What about port-knocking solutions? 🤔

@kayos@twtxt.net Actually this is a brilliant idea! 👌 I’ve written a few custom SSH daemons before 😅 What’s another more specific one fit-for-purpose 🤣 I might write one! Any special requirements you have? 🤔
