  1. Bom dia pessoal.
    Há algum tempo atrás tive problemas com a abertura de planilhas de Excel em meu servidor SAMBA. Sempre que o usuário tentava abrir planilha, aparecia uma mensagem informando que o mesmo estava em uso e questionava o usuário se desejava abri-la somente como leitura.
    Nessa época, inseri no meu smb.conf o seguinte parâmetro:

    ##### INÍCIO #####
    oplocks = no
    ##### FIM #####

    De uns dias para cá, esse problema voltou a ocorrer, mesmo com o parâmetro acima, então também inseri a seguinte linha:

    ##### INÍCIO #####
    level2 oplocks = no
    ##### FIM #####

    Porém o problema ainda ocorre.

    Alguém poderia me ajudar?

  2. mas...
    ocorre realmente pq o arquivo esta sendo usado por dois usuarios ao mesmo tempo?

  3. coloca o seu smb.conf aqui que fica melhor para te ajudar....
    já tive esse problema também, mais olhando seu conf te dou a dica....

  4. Segue o meu smb.conf.

    #### INÍCIO ####

    # This is the main Samba configuration file. You should read the
    # smb.conf(5) manual page in order to understand the options listed
    # here. Samba has a huge number of configurable options (perhaps too
    # many!) most of which are not shown in this example
    # Any line which starts with a ; (semi-colon) or a # (hash)
    # is a comment and is ignored. In this example we will use a #
    # for commentry and a ; for parts of the config file that you
    # may wish to enable
    # NOTE: Whenever you modify this file you should run the command "testparm"
    # to check that you have not made any basic syntactic errors.
    #======================= Global Settings =====================================

    # 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

    # It should not be necessary to spell out the print system type unless
    # yours is non-standard. Currently supported print systems include:

    # printing = lprng
    printing = cups

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

    # This parameter will control whether or not Samba should obey PAM's
    # account and session management directives. The default behavior is
    # to use PAM for clear text authentication only and to ignore any
    # account or session management. Note that Samba always ignores PAM
    # for authentication in the case of encrypt passwords = yes

    #### FIM ####

    Acabei de perceber uma coisa... quando executo o comando smbstatus aparecem diversas conexões antigas. Essas conexões vão desde planilhas a arquivos executáveis.
    Existem conexões que estão datadas do começo de nov/08.

  5. então derrube-as!
    comente as linhas:
    read raw = yes
    write raw = yes

    reinicie o serviço...
    e veja se funciona...
