Sekundärer Nameserver Arbeiten auf dem sekundären Nameserver

Hauptkonfigurations Datei

• Transfer wird eigentlich nicht benötigt.
• Bei offiziellen Nameservern die Denic Server eintragen zur zum Bootstrap
• Zum Testen schalte ich den Zonentransfer von primären oft frei.
• vi /etc/bind/named.conf.options

options {
        directory "/var/cache/bind";
        allow-transfer     { 192.168.34.1; 192.168.34.2 ; 127.0.0.1 ;};
        allow-query        { 0.0.0.0/0 ;};
        allow-recursion    { 192.168.34.0/24 ; 127.0.0.1 ;};
        dnssec-validation no;
        listen-on-v6 { no; };
};

Die Zonen Dateien

• Der Typ ist "slave"
• Der Masterserver wir als IP angegeben

• vi /etc/bind/named.conf.local

zone "vulkan.int" {
    type slave;
    masters { 192.168.34.1; };
    file "vulkan.int";
};

zone "34.168.192.in-addr.arpa" {
    type slave;
    masters { 192.168.34.1; };
    file "34.168.192.in-addr.arpa";
};
