Wenn er den Port 12134 seinem SSHd selbst zugewiesen hat, dann nicht, andernfalls ja.

Nein, und wenn dann hätte ich es sofort abgeschaltet. Ich habe jetzt einfach mal den Port verändert weil es mich immer nervte. Ich darf es nur nicht mehr vergessen, das ich den Port verändert habe. Das ist mir schon mal passiert, und weil ich nicht mehr drauf kam, warum ich nicht mehr mit Putty Connecten konnte, habe ich mein System neu installiert. Und dann fand ich ein Dokument das ich selbst anlegte als Notiz. der Ärger war ziemlich groß! :D

Naja, fail2ban kann ja schon etwas einschränken und die Brute Force Attacken reduzieren.
Ich halte es nicht für die Beste Lösung aber dafür ist es i.O.

Wir sieben dann die IP Ranges auf Port 22 aus, auf denen Misst rein kommt. Ein seperates System gilt als Sprunghost, falls man sich doch mal aussperrt haben wir Zugriff darüber. Unsere LANs / WANs kennen wir ja auch.
Ich verstehe es, es ist leider lästig, aber es muss sein.
