nsmb.conf

Configuration hierarchy is made up of sections, parameters and values.

• Sections begin with a section name enclosed within square brackets:
  [section_name]

  Section names:

  • [default] ^†
  • [SERVER]
  • [SERVER:User]
  • [SERVER:User:share]
  may contain key = value lines.

  Keyword	Section
  	d S U s
  addr	- S - -	IP address of the SMB server
  dos charsets	d - - -	DOS charset
  nbns	d S - -	address of NetBIOS name server (WINS)
  nbscope	d S - -	NetBIOS scope
  nbtimeout	d S - -	timeout for NetBIOS name servers
  port445 [no_netbios]	d S - -	SMB TCP/UDP ports
  minauth=a	d S - -	minimum authentication level allowed
  streams [=yes]	d S - -	use NTFS Streams
  soft [=yes]	d S - -	Make the mount soft. Fail file system calls after n seconds.
  notify_off [=yes]	d S - -	Turn off notifications
  domain	d S U s	domain name to use when logging into the server.
  mc_prefer_wired[=yes]		Some Wi-Fi advertise faster speeds than wired .
  dir_cache_off[=yes]
  mc_on[=no		disable multichannel

  Minimum authentication levels

  kerberos	Other authications are not attempted.
  ntlmv2	Kerberos authentication if a Kerberos token can be obtained, otherwise NTLMv2 authentication . if the server doesn't support encrypted passwords, the authentication fails.
  ntlm	Kerberos authentication … NTLMv2 authentication and, if that fails, NTLMv1 authentication , with null in the LM hash. if the server doesn't support encrypted passwords, the authentication fails.
  lm	Lan Manager Kerberos authentication … including the LM hash; if the server doesn't support encrypted passwords, the authentication fails.
  none	as with lm Kerberos authentication … if the server doesn't support encrypted passwords, plain-text passwords are used.
  ntlmv2_off	Kerberos authentication … otherwise NTLMv1 authentication including the LM hash; If the server doesn't support encrypted passwords, plain-text passwords are used.

  "NetBIOS" as used below means "NetBIOS over TCP/IP."

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

  no_netbios	445	connect via port 445.
  netbios_only	NetBIOS	Do not attempt to connect via port 445.
  normal	445 or NetBIOS	(default) connect via port 445. If unsuccessful use NetBIOS.

  FILES

  /etc/nsmb.conf global configuration file. not present on OSX 10.9.5 as of 11/26/14
  ~/Library/Preferences/nsmb.conf The user's configuration file, conflicts are superceeded by the global file.

  EXAMPLES

  # Configuration file for example.com
             [default]
             minauth=ntlmv2
             streams=yes
             soft=yes
             notify_off=yes
             domain=DOMAIN
             [WIN98]
             addr=windows98.apple.com 

  The default section specifies that only Kerberos and NTLMv2 authentication should be attempted;
  Meaning that 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.

  Possibel global defaults

  #defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE
  #defaults write com.apple.desktopservices UseBareEnumeration -bool TRUE

  Packet Signing

  Turn off packet signing for SMB 2 and SMB 3 connections if:
  • Performance decreases when you connect to a third-party server.
  • You can't connect to a server that doesn't support packet signing.
  • You can't connect a third-party device to your macOS SMB server.
  /etc/nsmb.conf
[default]
signing_required=no Turn off packet signing on a macOS computer that hosts SMB shares: sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server SigningRequired -bool FALSE

  smbutil

  interface to the SMB requester

  smbutil [-hv] command [-options] [args]

  Controls SMB requester and issues commands.

  -h	outputs: usage: smbutil [-hv] subcommand [args] where subcommands are: help display help on specified subcommand lookup resolve NetBIOS name to IP address status resolve IP address or DNS name to NetBIOS names view list resources on specified host dfs list DFS referrals identity identity of the user as known by the specified host
  Commands :
  lookup [-w host] name	Resolve name to an IP address. The NetBIOS name server can be specified with -w host . Example: smbutil lookup kitchen Got response from 192.168.1.6 IP address of kitchen: 192.168.1.6 smbutil lookup sligiga # it's sleeping smbutil: unable to resolve sligiga: No route to host > echo $? 68
  smbutil status [-ae]server	Resolve server (IP address or DNS name) to NetBIOS workgroup and system name. -a all. -e names will be percent escaped Example: smbutil status kitchen Workgroup: RWSW Server: KITCHEN smbutil status -a smacpro Using IP address of smacpro: 192.168.1.3 NetBIOS Name Number Type Description SMACPRO 0x00 UNIQUE [Workstation Service] SMACPRO 0x20 UNIQUE [File/Print Server Service] WORKGROUP 0x00 GROUP [Domain Name]
  view //[domain;][user[password]@] server	List resources available on the specified server for the user user. example: smbutil view //kitchen Share Type Comment ------------------------------------------ IPC$ Pipe Remote IPC C$ Disk Default share Generic Text Only Printer Generic / Text Only HDimages Disk print$ Disk Printer Drivers DATA Disk BACKUP Disk DATA000 Disk APPS Disk ipx1600k Printer Canon pixma 1600 SYS Disk 15 shares listed from 15 available
