    NAME

    nsmbrc - configuration file for Solaris CIFS client requests
     
    

    SYNOPSIS

    $HOME/.nsmbrc
    

     

    DESCRIPTION

    Global behavior of the Solaris CIFS client is defined by property values that are stored in the Service Management Facility (SMF). The .nsmbrc file can be used to customize the behavior of the Solaris CIFS client on a per-user basis. Settings in the $HOME/.nsmbrc file are used unless they have security implications.

    An authorized user can use the sharectl command to set global values for these properties in SMF. See sharectl(1M).

    A regular user can change the global values when granted the "SMBFS Management" rights profile in the /user_attr file. See user_attr(4) and rbac(5).

    The SMBFS library first reads from SMF and then the $HOME/.nsmbrc file when determining which policy to apply to a particular server, user, or share. $HOME/.nsmbrc entries take precedence with the exception of the minauth property value. For minauth, the strongest authentication level specified is used. Sections are applied so that more specific sections override less specific sections. Not all keywords are valid in all sections.

    The configuration file is comprised of these four section types. Each section can include zero or more properties and associated values. The sections also have a hierarchical relationship with each other, as shown by the order of the following list:

    o Default section. Specifies the default property values to be used by all other sections unless specifically overridden.

    The section name appears in the .nsmbrc file as [default].

    o Server section. Specifies the property values to be used by sections that are related to the named server. These property values can be specifically overridden by a related user section or share section.

    The section name appears in the .nsmbrc file as [server-name]. server-name must use uppercase characters to match.

    o User section. Specifies the property values to be used by sections that are related to the named server and user. These property values can be specifically overridden by a related share section.

    The section name appears in the .nsmbrc as [server-name:username]. Both server-name and username must use uppercase characters to match.

    o Share section. Specifies the property values to be used by sections that are related to the named server, user, and share.

    The section name appears in the .nsmbrc as [server-name:username:share-name]. Both server-name and username must use uppercase characters to match.

    The end of each section is marked either by the start of a new section or by an end of file (EOF).

    The following list describes the properties and states in which sections they can be set:

    addr

    Specifies the DNS name or IP address of the CIFS server. This property can only be set in a server section. If this property is specified, it must specify a value as there is no default.

    domain

    Specifies the Windows domain name to use when authenticating with a server. The default value is WORKGROUP. This property can only be set in the default and server sections.

    minauth

    Is the minimum authentication level required, which can be one of kerberos, ntlmv2, ntlm, lm, or none. If minauth is set globally and in a user's .nsmbrc file, the stronger authentication setting are used whether set by the user or globally. This property can only be set in the default and server sections. The default value is ntlm.

    nbns

    Specifies the DNS name or IP address of the NetBIOS/WINS name server. This property can only be set by an administrator by using the sharectl command. This property can only be set in the default section. The default value is empty, nbns="".

    nbns_broadcast

    Specifies whether to perform NetBIOS/WINS broadcast lookups. Broadcast lookups are less secure than unicast lookups. To prevent broadcast lookups, set the value to no. This property has no effect if the nbns_enable property is set to no or false. This property can only be set by an administrator by using the sharectl command. This property can only be set in the default section. Valid values are yes, true, no, and false. The default value is yes.

    nbns_enable

    Specifies whether to perform NetBIOS/WINS name lookups. To force all lookups to be done through the name service switch (see nsswitch.conf(4)), set the value to no. This property can only be set by an administrator by using the sharectl command. This property can only be set in the default section. Valid values are yes, true, no, and false. The default value is yes.

    password

    Specifies the password to use when authenticating a server. The password property value is used as long as the .nsmbrc file can only be read and written by the owner. This property can be set in the default, server, user, and share sections.

    If you assign the hashed password from the smbutil crypt command to the password property, be sure to escape the special characters in the password.

    signing

    Specifies whether communications are digitally signed by SMB security signatures for the Solaris CIFS client. This property can only be set in the default and server sections. Valid values are disabled, enabled, and required. The default value is disabled.

    When set to disabled, the client permits the use of SMB security signatures only if the server requires signing. In such an instance, the Solaris CIFS client ignores local property values.

    When set to enabled, the client permits, but does not require, the use of SMB security signatures.

    When set to required, the client requires the use of SMB security signatures. So, if SMB security signatures are disabled on a CIFS server and a client has signing required, the client cannot connect to that server.

    timeout

    Specifies the CIFS request timeout. By default, the timeout is 15 seconds. This property can only be set in the default, server, and share sections.

    user

    Specifies the user name to use when authenticating a server. The default value is the Solaris account name of the user performing the authentication. This property can only be set in the default and server sections.

    workgroup

    Is supported for compatibility purposes and is a synonym for the domain property. Use the domain property instead.

     

    EXAMPLES

    The examples in this section show how to use the .nsmbrc file and the smbutil command to configure the ex.com environment.

    The ex.com environment is described by means of these sections and settings:

    o The default section describes the default domain, which is called MYDOMAIN, and sets a default user of MYUSER. These default settings are inherited by other sections unless property values are overridden.
    o FSERVER is a server section that defines a server called fserv.ex.com. It is part of the SALES domain.
    o RSERVER is a server section that defines a server called rserv.ex.com that belongs to a new domain called REMGROUP.

    Example 1 Using the $HOME/.nsmbrc Configuration File

    The following example shows how a user can configure the ex.com environment by creating the .nsmbrc file.

    All lines that begin with the # character are comments and are not parsed.

    # Configuration file for ex.com
    # Specify the Windows account name to use everywhere.
    [default]
    domain=MYDOMAIN
    user=MYUSER
    
    # The 'FSERVER' is server in our domain.
    [FSERVER]
    addr=fserv.ex.com
    
    # The 'RSERVER' is a server in another domain.
    [RSERVER]
    domain=REMGROUP
    addr=rserv.ex.com
    

    Example 2 Using the sharectl Command

    The following example shows how an authorized user can use sharectl commands to configure global settings for the ex.com environment in SMF.

    # sharectl set -p section=default -p domain=MYDOMAIN \
    -p user=MYUSER smbfs
    # sharectl set -p section=FSERVER -p addr=fserv.ex.com smbfs
    # sharectl set -p section=RSERVER -p domain=REMGROUP \
    -p addr=rserv.ex.com smbfs
    

    Example 3 Using the sharectl Command to Show Current Settings

    The following example shows how an authorized user can use the sharectl get command to view the global settings for smbfs in SMF. The values shown are those set by the previous example.

    # sharectl get smbfs
    [default]
     domain=MYDOMAIN
     user=MYUSER
    [FSERVER]
     addr=fserv.ex.com
    [RSERVER]
     domain=REMGROUP
     addr=rserv.ex.com
