NAME

mount_smbfs —

mount a shared resource from an SMB file server

SYNOPSIS

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

DESCRIPTION

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

The options are as follows:

-E cs1: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:srights

Assign access rights to the newly created connection.

-N

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:cgroup/sowner: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.

//user@server[:port1[:port2]]/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.

FILES

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

EXAMPLES

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 192.168.20.3 -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

STANDARDS

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:

Samba
Windows 95/98/ME/2000/NT4.0 (SPs 4, 5, 6)
IBM LanManager
NetApp

HISTORY

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