\u00a0<\/h1>\n

In diesem Tutorial zeigen wir Ihnen, wie Sie eine IP-Adresse in Fail2ban auf Ihrem Debian Linux VPS-Server<\/a> whitelisten k\u00f6nnen. Durch das Whitelisting einer IP-Adresse stellen Sie sicher, dass diese Adresse niemals von Fail2ban blockiert wird, selbst wenn sie die definierten Filterregeln ausl\u00f6st. Dies ist n\u00fctzlich, um legitime Benutzer oder Dienste vor versehentlichen Blockierungen zu sch\u00fctzen.<\/p>\n

Schritt 1: Fail2ban Konfigurationsdatei bearbeiten<\/h2>\n
    \n
  1. \n

    \u00d6ffnen Sie die Fail2ban Konfigurationsdatei jail.local<\/code> mit einem Texteditor (wenn Sie diese Datei noch nicht erstellt haben, kopieren Sie zuerst die Datei jail.conf<\/code>):<\/p>\n

    sudo cp \/etc\/fail2ban\/jail.conf \/etc\/fail2ban\/jail.local\r\nsudo nano \/etc\/fail2ban\/jail.local<\/code><\/pre>\n<\/li>\n
  2. \n
    Suchen Sie den Abschnitt [DEFAULT]<\/code> und f\u00fcgen Sie die IP-Adresse, die Sie whitelisten m\u00f6chten, zur ignoreip<\/code>-Option hinzu. Sie k\u00f6nnen mehrere IP-Adressen durch Leerzeichen trennen oder CIDR-Notation verwenden:<\/p>\n
    [DEFAULT]\r\nignoreip = 127.0.0.1\/8 ::1 192.168.1.0\/24 ihre_ip_adresse<\/code><\/pre>\n
    Ersetzen Sie ihre_ip_adresse<\/code> durch die tats\u00e4chliche IP-Adresse, die Sie whitelisten m\u00f6chten.<\/p>\n<\/li>\n
  3. \n
    Speichern und schlie\u00dfen Sie die Datei.<\/p>\n<\/li>\n<\/ol>\n
    Schritt 2: Fail2ban neu starten<\/h2>\n
    Starten Sie den Fail2ban-Dienst neu, um die \u00c4nderungen zu \u00fcbernehmen:<\/p>\n
    sudo systemctl restart fail2ban<\/code><\/pre>\n
    Schritt 3: Whitelisting \u00fcberpr\u00fcfen (optional)<\/h2>\n
    Sie k\u00f6nnen \u00fcberpr\u00fcfen, ob die IP-Adresse erfolgreich gewhitelistet wurde, indem Sie den Status eines bestimmten Jails abfragen. Ersetzen Sie [jail-name]<\/code> durch den Namen des Jails, f\u00fcr das Sie das Whitelisting \u00fcberpr\u00fcfen m\u00f6chten (z.B. sshd<\/code>):<\/p>\n
    sudo fail2ban-client status [jail-name]<\/code><\/pre>\n
    Die Ausgabe sollte die gewhitelisteten IP-Adressen im Abschnitt “ignorierte IP-Adressen” anzeigen.<\/p>\n
    Abschluss<\/h2>\n
    Sie haben nun gelernt, wie Sie eine IP-Adresse in Fail2ban auf Ihrem Debian Linux Server whitelisten k\u00f6nnen. Dies ist ein wichtiger Schritt, um sicherzustellen, dass legitime Benutzer oder Dienste nicht versehentlich blockiert werden, w\u00e4hrend Sie Ihren Server vor Brute-Force-Angriffen sch\u00fctzen.<\/p>\n
