Jeg vil gerne konfigurere en simpel bindingsserver, der er i stand til at fungere som en simpel videresender til OpenDNS servere.

Jeg vil ikke have min binding, men jeg kan spørge rodserverne, jeg vil have, at al trafik kun går til OpenDNS og måske fungerer som “cache” for det.

Hvordan dette kan opnås? Skal jeg deaktivere tipene til rodserverne på en eller anden måde? Er dette den korrekte procedure?

Mit gæt er at kommentere den zone “.”, Der serveres af rodserverne på named.conf.default-zones fil. Jeg læste dog, at de ikke-forespørgende rodservere også kan opnås ved at deaktivere rekursion, men deaktivering af rekursion ser ud til at føre til, at serveren ikke også kan udnytte videresenderne .. hvor min conf er forkert?

Conf er følgende:

named.conf

// This is the primary configuration file for the BIND DNS server named. // // Please read /usr/share/doc/bind9/README.Debian.gz for information on the // structure of BIND configuration files in Debian, *BEFORE* you customize // this configuration file. // // If you are just adding zones, please do that in /etc/bind/named.conf.local include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones"; 

named.conf.options

acl "trusted" { 127.0.0.1/8; 10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16; ::1; }; options { directory "/var/cache/bind"; # bind cache directory recursion no; # enables resursive queries allow-query { trusted; } ; allow-recursion { "none"; }; additional-from-cache no; allow-transfer { none; }; # disable zone transfers by default // If there is a firewall between you and nameservers you want // to talk to, you may need to fix the firewall to allow multiple // ports to talk.
