Ola Renato,

FIz as alterações que vc pediu. O /etc/bind/named.conf.default-zones, não existia no meu diretório, então copiei o named.conf para dentro dele. Fiz as alterações nos db.dnsdebian, db.dnsdebian.reverse.

Executei o /etc/init.d/bind9 restart, olha o resultado:

Stopping domain name service...: bind9rndc: connect failed: 127.0.0.1#953: connection refused
.
Starting domain name service...: bind9 failed!

Fui verificar o log:

Ola Renato,

Neste ponto eu eliminei a linha que vc sugeriu e "restartei" o processo

Observei que ele estava com problemas também no named.conf.default-zones, então comentei a linha também.

Ele está mandando uma mensagem de erro na linha 17 do db.dnsdebian, tentei comentar, tirar algumas "coisas" como o 1 no final do arquivo, mas ai o erro vai "subindo" !!!!

É amigo viver é muito fácil, se comparado com a instalação do BIND9 !!!!!!!!!!

Kra, o q tá acontecendo é q vc não retirou aquele named.conf q a gente havia feito anteriormente. O esquema era vc t feito backup dele e substituído pelo q t passei. Ah! Vou colocar aki o named.conf.options q ficou faltando, dae vai dar tudo certo. Segue abaixo:

named.conf.options

options {
directory "/var/cache/bind";

// 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. See http://www.kb.cert.org/vuls/id/800113

// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.

// forwarders {
// 0.0.0.0;
// };

auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};

Ola,

Fiz as alterações, renomiei os arquivos e gerei apartir dos arqivos que vc enviou no site, só fui copiando e colando, e tenho as seguintes mensagens do sistema:

tail -f /var/log/syslog

named-checkconf -z
/etc/bind/named.conf:13: missing ';' before end of file

Quando recebi essa mensagem fui dar uma olhada no named.conf:

cat 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";

E agora ???

Essa msg:

Na linha 13 do arquivo named.conf tá faltando um ponto-e-vírgula, só isso. Conserte e faça d novo.

As mensagens de erro com o mail, pode ser porque não configurei esse serviço no Linux ?

Quando executo o nslookup no XPvirtual, ele mostra para mim "os servidores padrão não estão disponíveis. Servidor: unknowm. Address: 172.16.0.27, nome=dnsdebian."

Quando executo o dig no linux:
dig dnsdebian

Ainda não consigo pingar pelo nome. Mas vc acha que isso pode ser um problema, numa rede pequena ? Não seria bom para a segurança, assim alguém mal intensionado não localizaria as estações tão fácil ?

É ae q tá, pra pingar vc deve fazer assim:

# ping ns1.dnsdebian

Assim vc consegue pingar, ok? Se vc colocar só o nome não pinga msm.
