    Default

    gibt es da schon eine Loesung?

    Die anderen Dienste (smtp, imap(s)) zu sichern ist mit fail2ban ja kein Problem. aber so richtig sinnvoll lesbar ist das open-xchange.log.0 ja nicht wirklich. Hat jemand da einen regex fuer? Oder gibt es eine elegante Methode, das anders zu loesen?

    Ich habe erstmal die HTTPS-Connections versucht zu limitieren, aber besonders mit Chrome werden die User damit sehr schnell gesperrt
