NAME
nsmbrc - configuration file for Solaris SMB client requests
SYNOPSIS
$HOME/.nsmbrc
DESCRIPTION
Global behavior of the Solaris SMB client is defined by pro-
perty values that are stored in the Service ManagementFacility (SMF). The .nsmbrc file can be used to customize
the behavior of the Solaris SMB client on a per-user basis.
Settings in the $HOME/.nsmbrc file are used unless they have
security implications.An authorized user can use the sharectl command to set glo-
bal values for these properties in SMF. See sharectl(1M). A regular user can change the global values when granted the"SMBFS Management" rights profile in the /user_attr file.
See user_attr(4) and rbac(5).
The SMBFS library first reads from SMF and then the$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 shareSunOS 5.11 Last change: 19 Mar 2010 1

section.The section name appears in the .nsmbrc file as
[server-name]. server-name must use uppercase char-
acters 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 user-
name 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 SMB 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. domainSpecifies the Windows domain name to use when authenti-
cating 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. IfSunOS 5.11 Last change: 19 Mar 2010 2

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. nbnsSpecifies 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 pro-
perty 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 pro-
perty 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.SunOS 5.11 Last change: 19 Mar 2010 3

signing Specifies whether communications are digitally signed by SMB security signatures for the Solaris SMB client. Thisproperty can only be set in the default and server sec-
tions. 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 SMB 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 SMB server and a client has signing required, the client cannot connect to that server. timeout Specifies the SMB 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 sec-
tions and settings:SunOS 5.11 Last change: 19 Mar 2010 4

o The default section describes the default domain, which is called MYDOMAIN, and sets a default user of MYUSER. These default settings are inherited byother sections unless property values are overrid-
den. 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 theex.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

Example 3 Using the sharectl Command to Show Current Set-
tings 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
