    Padrão Erro estranho no samba, ninguem acessa nada!

    Opa, blz?
    O samba aqui onde eu trabalho funcionava perfeitamente...
    De repente começou a dar acesso negado para todos os usuarios em todos os arquivos.
    Se eu logo pelo linux tenho acesso normalmente (leitura e escrita, execucao nao posso testar).
    O estranho é o seguinte, mesmo as permissoes dos usuarios setadas corretamente, eles nao conseguem ler nenhum arquivo.
    Se eu logado no linux, pego o arquivo edito ele no vi e salvo ele, os usuarios conseguem ser ele, mas nao conseguem executá-lo

    Em anexo segue o nosso smb.conf
    Código :
    # workgroup = NT-Domain-Name or Workgroup-Name
       workgroup = BIFERCO
    # server string is the equivalent of the NT Description field
       server string = Samba Server %v
    # This option is important for security. It allows you to restrict
    # connections to machines which are on your local network. The
    # following example restricts access to two C class networks and
    # the "loopback" interface. For more examples of the syntax see
    # the smb.conf man page
    ;   hosts allow = 192.168.1. 192.168.2. 127.

    # than setting them up individually then you'll need this

    # yours is non-standard. Currently supported print systems include:

    # Uncomment this if you want a guest account, you must add this to /etc/passwd

    # that connects

    # enabled, then PAM will be used for password changes when requested

    Como está a permissão de grupo desses diretórios dentro do Linux?

    Qual o grupo dos usuários?

    o Estranho foi que depois de backupear, testar mcher e fuçar... Ele voltou a funcionar do nada..

    Até agora eu não sei explicar isto pro meu patrão..

    O que e isso? Bug do samba, erro de hardware ?
