Re: Securing zone transfer and DDNS

Show key headers only | View raw

Thanks everybody for the answers.
I have one more question - how can I block every update for every zone in options section using update-policy?

logging { ... };

options {
        directory "/var/named";
        dnssec-enable yes;
        recursion yes;
        allow-recursion { 127.0.0.1; };
        allow-transfer { none; };
        allow-update { none; }; <<<<<<<<<<<<<<<<
};

key "rndc-key" { ... };

controls {
        inet 127.0.0.1 port 953
                allow { 127.0.0.1; } keys { "rndc-key"; };
};

key "transfer-key" { ... };

key "ddns-key" { ... };

zone "." IN {
        type hint;
        file "named.ca";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
};

zone "my.zone" IN {
        type master;
        file "my.zone";
        allow-transfer { key transfer-key; };
        update-policy {
                grant ddns-key zonesub ANY;
        };
};

Pozdrawiam,
