Eu gostaria de configurar o bind9 no meu computador local, de modo que as consultas comuns do DNS como com, de, net sejam encaminhadas para o DNS do Google e as outras personalizadas do OpenNic como bbs, dyn, free sejam encaminhadas para um OpenNIC. Servidor DNS.
O dns-server não deve fazer o cache ou baixar todos os arquivos de zona dos servidores OpenNIC-DNS.
Você pode me ajudar?
Aqui está minha configuração que não funciona:
//named.conf:
include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";
.
//named.conf.default-zones
zone "localhost" {
type master;
file "/etc/bind/db.local";
};
zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};
zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};
zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};
.
// named.conf.local:
// replace all '...' with the following:
// type forward;
// forwarders {78.138.98.82; 78.138.97.33;};
// forward only;
zone "dns.opennic.glue" in { ... };
zone "bbs" in { ... };
zone "dyn" in { ... };
zone "free" in { ... };
zone "fur" in { ... };
zone "geek" in { ... };
zone "gopher" in { ... };
zone "indy" in { ... };
zone "ing" in { ... };
zone "micro" in { ... };
zone "neo" in { ... };
zone "null" in { ... };
zone "opennic.glue" in { ... };
zone "oss" in { ... };
zone "oz" in { ... };
zone "parody" in { ... };
zone "pirate" in { ... };
.
// named.conf.options
options {
directory "/var/cache/bind";
forwarders { 8.8.8.8; 8.8.4.4; };
forward only;
dnssec-validation auto;
auth-nxdomain no;
};
