[Ubuntu-BR] Servidor DNS

[TiagoBast]

Ola Pessoal, estou tentando montar um servidor de dns. Estou tendo
dificuldades de configuração de DNS estou encaminhando os arquivos de
configuração para voces darem uma olha.

Arquivo NAMED
include "/etc/bind/named.conf.options";

// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/etc/bind/db.root";
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

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";
};
// zone "com" { type delegation-only; };
zone "meudominio.com" {
        type master;
        file "/etc/bind/db.meudominio";
};

zone "ipreverso.in-addr.arpa" {
        type master;
        file "/etc/bind/db.rev.meudominio";
};
