1. Sollte man solche kontinuierlichen Angriffsversuche irgendwo
melden?
Du kannst eine Mail mit Auszügen aus Deinen Logfiles an die
abuse-Adresse senden. Erwähne dabei, welche Zeitzone Dein Server für die
fail2ban erzeugt (auf Wunsch) übrigens entsprechende Mails, die man mehr
oder weniger 1:1 an die Abuse-Adresse für die IP senden kann:

Die Zeitzone und ein kurzes Anschreiben und fertig. Weiterer Vorteil,
die IP darf erstmal nicht weiter mit dem Server sprechen und man kann
entspannt auf eine Rückmeldung warten.
Schö!
