🌸 NAME 🌸

pknlusr — userspace monitor for successful xt_pknock matches 💖

Okay so this is pknlusr(8) from the xtables-addons crew, and she is literally here to watch your port-knocking wins. No cap. ✨

✨ Synopsis ✨

pknlusr [group-id]

That's it, bestie. Optional [group-id] goes in, notifications come out. 🦋

💅 Description 💅

So xt_pknock is an xtables match extension that implements the whole port knocking thing. It can be configured to send information about each successful match through a netlink socket to userspace. And pknluser — yes, that's literally how the page spells it right there — listens for those notifications. 👀

By default, pknlusr listens for messages sent to netlink multicast group 1. If you want a different group, another group ID may be passed as a command-line argument. Slay. ✨

Real talk: default is group 1, and your custom group ID goes in as the argument. That's the vibe described here. 💅
