.Sh DESCRIPTION
The
.Nm
command mounts a share from a remote server using SMB/CIFS protocol.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl E Ar cs1 Ns Cm \&: Ns Ar cs2
Specifies local
.Pq Ar cs1
and server's
.Pq Ar cs2
character sets.
.It Fl I Ar host
Do not use NetBIOS name resolver and connect directly to
.Ar host ,
which can be either a valid DNS name or an IP address.
.It Fl L Ar locale
Use
.Ar locale
for lower/upper case conversion routines.
Set the locale for case conversion.
By default,
.Nm
tries to use an environment variable
.Ev LC_*
to determine it.
.It Fl M Ar crights Ns Cm \&: Ns Ar srights
Assign access rights to the newly created connection.
.It Fl N
Do not ask for a password.
At run time,
.Nm
reads the
.Pa ~/.nsmbrc
file for additional configuration parameters and a password.
If no password is found,
.Nm
prompts for it.
.It Fl O Ar cowner Ns Cm \&: Ns Ar cgroup Ns Cm \&/ Ns Ar sowner Ns Cm \&: Ns Ar sgroup
Assign owner/group attributes to the newly created connection.
.It Fl R Ar retrycount
How many retries should be done before the SMB requester decides to drop
the connection.
Default is 4.
.It Fl T Ar timeout
Timeout in seconds for each request.
Default is 15.
.It Fl U Ar username
Username to authenticate with.
.It Fl W Ar workgroup
This option specifies the workgroup to be used in the authentication request.
.It Fl c Ar case
Set a
.Ar case
option which affects name representation.
.Ar case
can be one of the following:
.Bl -tag -width ".Em Value"
.It Em Value
.Em Meaning
.It Cm l
All existing file names are converted to lower case.
Newly created file gets a lower case.
.It Cm u
All existing file names are converted to upper case.
Newly created file gets an upper case.
.El
.It Fl f Ar mode , Fl d Ar 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.
.Pp
Note that these permissions can differ from the rights granted by SMB
server.
.It Fl u Ar uid , Fl g Ar gid
User ID and group ID assigned to files.
The default are owner and group IDs from
the directory where the volume is mounted.
.It Cm \&// Ns Ar user Ns Cm \&@ Ns Ar server Ns Oo Cm \&: Ns Ar port1 Ns Oo Cm \&: Ns Ar port2 Oc Oc Ns Cm \&/ Ns Ar share
The
.Nm
command will use
.Ar server
as the NetBIOS name of remote computer,
.Ar user
as the remote user name and
.Ar share
as the resource name on a remote server.
Optional
.Ar port1
and
.Ar port2
arguments can be used to override default values of port numbers used
by communication protocols.
For SMB over NetBIOS default value for
.Ar port1
are 139, and
.Ar port2
are 137.
.It Ar node
Path to mount point.
.El
.Sh FILES
.Bl -tag -width ".Pa /etc/nsmb.conf" -compact
.It Pa ~/.nsmbrc
Keeps user-specific static parameters for connections and other information.
See
.Pa /usr/share/examples/smbfs/dot.nsmbrc
for details.
.It Pa /etc/nsmb.conf
Keeps system-wide static parameters for connections and other information.
.El
.Sh EXAMPLES
The following example illustrates how to connect to SMB server
.Dq SAMBA
as user
.Dq GUEST ,
and mount shares
.Dq PUBLIC
and
.Dq TMP :
.Bd -literal -offset indent
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
.Ed
.Pp
It is also possible to use
.Xr fstab 5
for smbfs mounts (the example below does not prompt for a password):
.Pp
.Dl "//guest@samba/public    /smb/public     smbfs  rw,noauto,-N 0   0"
