NSMB.CONF(5) File Formats Manual NSMB.CONF(5)

nsmb.confconfiguration file for server message block (SMB1/CIFS) requests

The nsmb.conf file contains information about the computers, users, and shares or mount points for the SMB network protocol.

The configuration files are loaded in the following order:

  1. ~/.nsmbrc
  2. /etc/nsmb.conf

As a result, /etc/nsmb.conf settings override those in ~/.nsmbrc.

The configuration hierarchy is made up of several sections, each section containing a few or several lines of parameters and their assigned values. Each of these sections must begin with a section name enclosed within square brackets, similar to:

[section_name]

The end of each section is marked by either the start of a new section, or by the abrupt ending of the file, commonly referred to as the EOF. Each section may contain zero or more parameters such as:

[section_name]
key=value

where key represents a parameter name, and value would be the parameter's assigned value.

The SMB library uses the following information for section names:

[default]
[SERVER]
[SERVER:USER]
[SERVER:USER:SHARE]

Possible keywords may include:

Section Comment
A B C D
addr - + - - IP address of SMB server
charsets - + + + local:remote charset pair
nbns + + - - address of NetBIOS name server (WINS)
nbscope + + - - NetBIOS scope
nbtimeout + + - - timeout for NetBIOS name servers
password - - + + plain text or simple encrypted password used to access the given share
retry_count + + - - number of retries before connection is marked as broken
timeout + + - - SMB request timeout
workgroup + + + + workgroup name

/etc/nsmb.conf
The default remote mount-point configuration file.
~/.nsmbrc
The user specific remote mount-point configuration file.

What follows is a sample configuration file which may, or may not match your environment:

# Configuration file for example.com
[default]
workgroup=SALES
# The 'FSERVER' is an NT server.
[FSERVER]
charsets=koi8-r:cp866
addr=fserv.example.com
# User specific data for FSERVER
[FSERVER:MYUSER]
password=$$16144562c293a0314e6e1

All lines which begin with the ‘#’ character are comments and will not be parsed. The “default” section describes the default workgroup or domain, in this case “SALES”. The next section depicted here as “FSERVER”, defines a server section and then assigns it a charset which is only required when Cyrillic characters are not used. The hostname value, “fserv.example.com”, is also assigned in this section. “FSERVER:USER”, defines the user settings and is useful for saving the password used during a specific connection. The password may be plaintext or obfuscated using simple encryption. The simple encrypted password starts with the `$$1' symbols. Warning: the encryption function is very weak and intended only to hide clear text passwords. If the use of simple encryption is desired, the following command may be used on a password:

smbutil crypt

smbutil(1), mount_smbfs(8)
