Vence a resolução do nome do host nss não está funcionando

Question

Estou tentando obter a resolução de nomes de vitórias. Eu pensei ter entendido o passo necessário, mas não consigo fazer funcionar.

A caixa está executando o SLES 12 SP1.

Isso é o que eu fiz:

• Adicionado um servidor de vitórias a /etc/samba/smb.conf :

  [global]
      wins server = 10.3.4.60
  

• Ativado e iniciado winbind.service :

  # systemctl status winbind.service 
  winbind.service - Samba Winbind Daemon
     Loaded: loaded (/usr/lib/systemd/system/winbind.service; enabled)
     Active: active (running) since Tue 2016-05-31 13:25:35 SAST; 1h 27min ago
   Main PID: 32111 (winbindd)
     Status: "winbindd: ready to serve connections..."
     CGroup: /system.slice/winbind.service
             ├─32111 /usr/sbin/winbindd -D
             └─32112 /usr/sbin/winbindd -D

• Adicionado o wins service ao banco de dados nsswitch hosts :

  # grep hosts /etc/nsswitch.conf 
  hosts:      files dns wins
  

Se eu chamar getent e especificar o wins service, funcionará:

# getent -s wins hosts VT53TESTSQL01
10.6.27.20      VT53TESTSQL01

Mas chamar getent com o conjunto de serviços padrão não funciona:

# getent hosts VT53TESTSQL01
<nothing returned>

Não tenho ideia do que senti falta. Alguma dica sobre como fazer isso funcionar?

Você já tentou reinicializar?

de man nsswitch.conf :

Within each process that uses nsswitch.conf, the entire file is read only once. If the file is later changed, the process will continue using the old configuration.
