mount_smbfs – mount a shared resource from an SMB file server



mount_smbfs [-E cs1 amp;:cs2] [-I host] [-L locale] [-M crights amp;:srights] [-N] [-O cowner amp;:cgroup amp;/sowner amp;:sgroup] [-R retrycount] [-T timeout] [-U username] [-W workgroup] [-c case] [-d mode] [-f mode] [-g gid] [-n opt] [-u uid] amp;//useramp;@ server[amp;: port1 [amp;: port2]]amp;/ sharenode


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

The options are as follows:
-E cs1 amp;:cs2
  Specifies local (cs1) and server's (cs2) character sets.
-I host
  Do not use NetBIOS name resolver and connect directly to host, which can be either a valid DNS name or an IP address.
-L locale
  Use locale for lower/upper case conversion routines. Set the locale for case conversion. By default, mount_smbfs tries to use an environment variable LC_* to determine it.
-M crights amp;:srights
  Assign access rights to the newly created connection.
  Do not ask for a password. At run time, mount_smbfs reads the ~/.nsmbrc file for additional configuration parameters and a password. If no password is found, mount_smbfs prompts for it.
-O cowner amp;:cgroup amp;/sowner amp;:sgroup
  Assign owner/group attributes to the newly created connection.
-R retrycount
  How many retries should be done before the SMB requester decides to drop the connection. Default is 4.
-T timeout
  Timeout in seconds for each request. Default is 15.
-U username
  Username to authenticate with.
-W workgroup
  This option specifies the workgroup to be used in the authentication request.
-c case
  Set a case option which affects name representation. case can be one of the following:
Value Meaning
l All existing file names are converted to lower case. Newly created file gets a lower case.
u All existing file names are converted to upper case. Newly created file gets an upper case.
-f 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.

-u uid , -g gid
  User ID and group ID assigned to files. The default are owner and group IDs from the directory where the volume is mounted.
amp;//user amp;@server[ amp;:port1[ amp;:port2 ]] amp;/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. Optional port1 and port2 arguments can be used to override default values of port numbers used by communication protocols. For SMB over NetBIOS default value for port1 are 139, and port2 are 137.
node Path to mount point.


~/.nsmbrc Keeps user-specific static parameters for connections and other information. See /usr/share/examples/smbfs/dot.nsmbrc for details.
  Keeps system-wide static parameters for connections and other information.


The following example illustrates how to connect to SMB server "SAMBA" as user "GUEST", and mount shares "PUBLIC" and "TMP":
mount_smbfs -I samba.mydomain.com //guest@samba/public /smb/public
mount_smbfs -I -E koi8-r:cp866 //guest@samba/tmp /smb/tmp

It is also possible to use fstab(5) for smbfs mounts (the example below does not prompt for a password):

    //guest@samba/public /smb/public smbfs rw,noauto,-N 0 0


smbutil(1), nsmb.conf(5)

mount_smbfs offers support for SMB/CIFS/SMB1. It does not support newer versions of the protocol like SMB2 and SMB3. SMB2 and SMB3 are supported by software available in the ports(7) collection.

The list of supported SMB servers includes:
Windows 95/98/ME/2000/NT4.0 (SPs 4, 5, 6)
IBM LanManager


SMB/CIFS protocol and SMB/CIFS file system implementation first appeared in FreeBSD 4.5 .
