mount_smbfs — mount a shared resource from an SMB file server

mount_smbfs [-N] [-o options] [-d mode] [-f mode] [-h] [-s] [-t gmt_token] [-v] //[domain;][user[:password]@]server[/share] path

The mount_smbfs command mounts a share from a remote server using SMB/CIFS protocol.

The options are as follows:

Do not ask for a password. At run time, mount_smbfs reads the ~/Library/Preferences/nsmb.conf file for additional configuration parameters and a password. If no password is found, mount_smbfs prompts for it.
Options passed to mount(2) are specified with the -o option followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings. Additional options supported by the mount_smbfs are as follows:
nobrowse
This option indicates that the mount point should not be visible via the GUI (i.e., appear on the Desktop as a separate volume).
automounted
Set flags on the mountpoint to indicate that the volume has been mounted by the automounter.
nostreams
Don't use NTFS Streams even if they are supported by the server.
soft
Make the mount soft. Fail file system calls after a number of seconds.
nonotification
Turn off using notifications for this volume.
nodatacache
Turn off using file data caching for this volume.
nomdatacache
Turn off using meta data caching for this volume.
sessionencrypt
Force session encryption to be used
shareencrypt
Force share encryption to be used for that share and also for IPC$ traffic
filemode
Specify permissions that should be assigned to files. The value must be specified as an octal number. Default value is taken from mount point.


Note that these permissions can differ from the rights granted by SMB server.

dirmode
Specify permissions that should be assigned to directories. The value must be specified as an octal number. Default value adds execute permission where the file mode gives read permission.


Note that these permissions can differ from the rights granted by SMB server.

snapshot
Do a read only mount using the specific snapshot of the share. A new session is created to allow multiple snapshots of the same share to be mounted. Value must be in GMT format e.g. @GMT-YYYY.MM.DD-HH.MM.SS
nopassprompt
Do not ask for a password. At run time, mount_smbfs reads the ~/Library/Preferences/nsmb.conf file for additional configuration parameters and a password. If no password is found, mount_smbfs prompts for it.
forcenewsession
Force a new session to be created to the server.
mode, -d mode
Specify permissions that should be assigned to files and directories. The values must be specified as octal numbers. Default value for the file mode is taken from mount point, default value for the directory mode adds execute permission where the file mode gives read permission.

Note that these permissions can differ from the rights granted by SMB server.

Prints a help message, much like the SYNOPSIS above.
Force a new session to be created to the server.
gmt_token
Do a read only mount using the specific snapshot of the share. A new session is created to allow multiple snapshots of the same share to be mounted. Value must be in GMT format e.g. @GMT-YYYY.MM.DD-HH.MM.SS
Prints version.
//[domain;][user[:password]@] server[/share]
The mount_smbfs command will use server as the NetBIOS name of remote computer, user as the remote user name and share as the resource name on a remote server. Domain and/or password may be specified here. If user is omitted the logged in user id will be used. Omitting share is an error when mount_smbfs is run from the command line, otherwise a browsing dialogue is presented.
path
Path to mount point.

nsmb.conf
Keeps static parameters for connections and other information. See man nsmb.conf for details.

This example shows the proper url to use to mount the share PUBLIC from the SMB server myserver :

mkdir /smb/public
mount -t smbfs //username:userpass@myserver/PUBLIC /smb/public
This example shows the proper url to use to mount the share PUBLIC from the SMB server myserver as guest: 
mkdir /smb/public
mount -t smbfs //guest:@myserver/PUBLIC /smb/public
Note: You should always use the system mount command and never call mount_smbfs directly.

mount(2), nsmb.conf(5), mount(8), umount(8)
