[resolvido] bind dns nao resolve

[fabiopratta]

Seguinte galera bom dia a todos configurei meu bind para resolver o dns de meu site mais ele não resolve por dns so por ip alguem sabe como fazer ele reconher tipo

dominio.com.br ---> dns1.dominio.com.br --> dns2.dominio.com.br

desde ja agradeço

[renato-barbosa]

Pelo que entendi, voce precisa usar cname.

Veja se é algo do tipo: http://www.vivaolinux.com.br/etc/acme.com.dns-dias_pcf

Basta configurar os endereços e depois os cnames.

Espero ter ajudado.

renato obrigado pela resposta mais num manjo muito de dns tipo eu configurei a bind aqui tal no registro.br ele responde pelo dominio.com.br mais por ip... e num sei se assim funcionaria .. obrigado novamente

Você precisa resolver esse erro... provavelmente vc separou o nome do arquivo em duas linhas, no arquivo de configuração?

Seguinte galera bom dia a todos configurei meu bind para resolver o dns de meu site mais ele não resolve por dns so por ip alguem sabe como fazer ele reconher tipo

dominio.com.br ---> dns1.dominio.com.br --> dns2.dominio.com.br

desde ja agradeço

Só por curiosidade... vc já registrou esse domínio?

[fabiopratta]

ja registrei so nao acertei o pagamento ainda mais vou fazer isso pq num posso deixar as config certas sem registro???

[zekkerj]

Pode e deve, pois o registro só é efetivado quando os servidores primário e secundário estiverem funcionando. Mas só vai começar a resolver fora de sua rede local quando o registro for efetivado.

intao eu registrei lah agora porem ele pede 2 serves de dns coloquei como primario ns1.emarketingperaltas.com.br e meu ip e como segundario ns2.emarketingperaltas.com.br com o msm ip, pois nao tenho 2 ips aqui com server dns so esse linux msm, mais deu erro tem como diblar isso no registro.br?

obrigado

[fabiopratta]

ha so mais uma coisa o erro que da no registro.br é hostname duplicado....

[zekkerj]

Não pode ser o mesmo ip pra primário e secundário. A idéia é que os servidores primário e secundário funcionam em regime de redundância, quando o primário não está disponível o secundário assume. Se os dois são a mesma máquina, vc não vai ter redundância.

Vc até pode colocar os dois na mesma máquina na hora do registro, mas nesse caso a máquina tem que responder em 2 ips diferentes (como o colega Master_ fez neste tópico).

Vc também pode entrar em contato com o seu provedor e pedir a ele para hospedar seu DNS secundário. Obviamente isso terá um custo que vcs terão que negociar.

[fabiopratta]

intao eu teria que colocar outra placa de rede no meu server e configurar esse outro ip é isso???

[zekkerj]

Não precisa colocar outra placa de rede, vc pode configurar um ip secundário na mesma placa. Mas veja que esse IP precisa ser conectável, ou seja, se vc tem uma faixa de IPs válidos, tem que usar um IP livre dessa mesma faixa. Se só tem um IP, deve requisitar mais um ao seu provedor.
