O que significa “Certifique-se de que o local vem antes de ligar no nsswitch”?

Question

Joining to AD Domain:   *******
With Computer DNS Name: (null)


Error: Required configuration stage not enabled [code 0x0000a606]

The configuration of module 'set computer hostname' is required. Please either allow this configuration stage to be performed automatically (by passing '--enable hostname'), or
manually perform these configuration steps and rerun the domain join:

The following step(s) are required:
    Give the machine a fully-qualified domain name. If performed automatically, the fqdn will be set through /etc/hosts to 'proj.users.campus', but it is possible to use a
    different fqdn and/or set it through dns instead of /etc/hosts. However in all cases, the fqdn must follow standard DNS naming conventions, and have a period in the name.
    The following steps will be used if the fqdn is set automatically:
        * Make sure local comes before bind in nsswitch
        * Add a loopback entry in /etc/hosts and put the fqdn as the primary name

O segundo erro que penso ter abordado. Eu não entendi o primeiro embora.

O que Garante que o local venha antes de ligar em nsswitch significa?

    

Answer 1

What does Make sure local comes before bind in nsswitch mean?

Em /etc/nsswitch.conf na linha "host: .." arquivos antes do dns. Exemplo:

Correct
hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4  

Not correct
hosts:          dns files 

    

Answer 2

Eu acho que significa que no arquivo /etc/nsswitch.conf, a linha que controla as fontes para o DNS deve direcionar as pesquisas de nomes para serem de arquivos locais antes de qualquer outra fonte de nomenclatura como bind

então você deve ter uma linha como esta

hosts:          files dns mdns4_minimal

em vez disso

hosts:          dns files mdns4_minimal
