@gemlog I'm still freaking out seeing it today. Especially when this happens to some machine you've set up years ago and now has life of its own. You realize it was going on for days and you're like: "Why the hell didn't fail2ban kick in?!" 😱
And fail2ban didn't kick in of course because it's so old that it doesn't even know what IPv6 is and it never occurred to you this could ever happen.
Yeah, this is what log monitoring is for 🤭
