Mit allowguest=no und/oder iptables,fail2ban etc

 

[MET]

Diese Art von Müll erhalte ich seit allowguest=no gesetzt wurde; vorher war es anderer Müll. Ja, iptables, fail2ban etc ... hatte mich sehr lange damit abgequält bis ich dann endlich einmal herausfand, dass das 'root' auf dem gemieteten vServer nicht ein vollwertiges ist ... habe die Zugänge dann anders abgesichert. Anscheinend ist es eine Frage entweder den vServer zu wechseln oder den Müll zu akzeptieren.

Dann würde ich aufhören den default context zu nutzen.
Sobald man im Internet ist hat man solche Requests immer.
