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

NAME
     nsmb.conf -- configuration file for SMB requests

DESCRIPTION
     The nsmb.conf file contains information about the computers and shares or mount points for the SMB net-work network
     work protocol.

     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:

     A)      [default]
     B)      [SERVER]
     C)      [SERVER:SHARE]

     Possible keywords may include:

     Keyword             Section    Default    Comment
                         A B C      Values
     addr                - + -                 DNS name or IP address of server
     nbtimeout           + + -      1s         Timeout for resolving a NetBIOS name
     minauth             + + -      NTLM       Minimum authentication level allowed
     port445             + + -      normal     How to use SMB TCP/UDP ports
     streams             + + +      yes        Use NTFS Streams if server supported
     soft                + + +                 Make the mount soft
     notify_off          + + +      no         Turn off using notifications
     kloglevel           + - -      0          Turn on smb kernel logging
     smb_neg             + - -      normal     How to negotiate SMB 2.x
     signing_required    + - -      false      Turn off smb client signing

     The minimum authentication level can be one of:

     kerberos  Kerberos - NTLMv2, NTLM, LM, and plain-text password authentication are not attempted.

     ntlmv2    NTLMv2 - Kerberos authentication is attempted if a Kerberos token can be obtained, otherwise
               NTLMv2 authentication is attempted; if the server doesn't support encrypted passwords, the
               authentication fails.

     ntlm      NTLM - Kerberos authentication is attempted if a Kerberos token can be obtained, otherwise
               NTLMv2 authentication is attempted and, if that fails, NTLMv1 authentication is attempted,
               with zeroes in the LM hash; if the server doesn't support encrypted passwords, the authenti-cation authentication
               cation fails.

     lm        LM - Kerberos authentication is attempted if a Kerberos token can be obtained, otherwise
               NTLMv2 authentication is attempted and, if that fails, NTLMv1 authentication is attempted,
               including the LM hash; if the server doesn't support encrypted passwords, the authentication
               fails.

     none      none - The same as lm except that, if the server doesn't support encrypted passwords, plain-text plaintext
               text passwords are used. Required for servers that don't support extended security.

     (Note: "NetBIOS" as used below means "NetBIOS over TCP/IP.")

     "How to use SMB TCP/UDP ports" can be one of:

     normal        Attempt to connect via port 445. If that is unsuccessful, try to connect via NetBIOS.

     netbios_only  Do not attempt to connect via port 445.

     no_netbios    Attempt to connect via port 445. If that is unsuccessful, do not try to connect via Net-BIOS. NetBIOS.
                   BIOS.

     "How to negotiate SMB 2.x" can be one of:

     normal     Negotiate with SMB 1.x and attempt to negotiate to SMB 2.x.

     smb1_only  Negotiate with only SMB 1.x.

     smb2_only  Negotiate with only SMB 2.x. This also will set no_netbios.

FILES
     /etc/nsmb.conf  The global configuration file.

     ~/Library/Preferences/nsmb.conf
                     The user's configuration file, conflicts will be overwritten by the global file.

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

           # Configuration file for example.com
           [default]
           minauth=ntlmv2
           streams=yes
           soft=yes
           notify_off=yes
           [WINXP]
           addr=windowsXP.apple.com

     All lines which begin with the `#' character are comments and will not be parsed.  The ``default'' sec-tion section
     tion specifies that only Kerberos and NTLMv2 authentication should be attempted; NTLM authentication
     should not be attempted if NTLMv2 authentication fails, and plain-text authentication should not be
     attempted if the server doesn't support encrypted passwords.
