Ich habe einen CentOS 6-Server, der sich in den letzten Wochen schlecht verhalten hat. Ich habe versucht, das Netzwerk zu verfolgen, Einstellungen anzupassen und viele kluge Leute dazu befragt (weitere Informationen finden Sie in dieser Frage:Etwas schließt Verbindungen in meinen CentOS-VMs – wie kann ich das Problem am besten beheben?)
Das Problem ist in den letzten 3-4 Tagen nicht aufgetreten, daher war ich der Annahme nahe, dass einige der Anpassungen einen Unterschied bewirkt hatten. Aber jetzt ist es innerhalb einer Stunde zweimal passiert. Ich habe angefangen, in den Protokollen nachzuschauen. Und bin dabei über Folgendes gestolpert /var/log/nginx/access.log:

... und viele mehr!
Dies ist ungefähr beide Male passiert, als ich das Problem gesehen habe. Weiß jemand, ob das in Ordnung ist – oder, wenn nicht, was der beste Weg ist, es zu blockieren?
Danke!

Ich habe es wie vorgeschlagen gemeldet – und dann diese IP-Adresse in meinem Nginx blockiert.
Also habe ich heute noch einmal nachgeschaut – und jetzt habe ich eine Menge ähnlicher Anfragen – nur von einer anderen IP.
