DESCRIPTION

       This tool is part of the samba(7) suite.

       smbclient is a client that can 'talk' to an SMB/CIFS server. It offers
       an interface similar to that of the ftp program (see ftp(1)).
       Operations include things like getting files from the server to the
       local machine, putting files from the local machine to the server,
       retrieving directory information from the server and so on.


OPTIONS

       servicename
           servicename is the name of the service you want to use on the
           server. A service name takes the form //server/service where server
           is the NetBIOS name of the SMB/CIFS server offering the desired
           service and service is the name of the service offered. Thus to
           connect to the service "printer" on the SMB/CIFS server
           "smbserver", you would use the servicename //smbserver/printer

           Note that the server name required is NOT necessarily the IP (DNS)
           host name of the server ! The name required is a NetBIOS server
           name, which may or may not be the same as the IP hostname of the
           machine running the server.

           The server name is looked up according to either the -R parameter
           to smbclient or using the name resolve order parameter in the
           smb.conf(5) file, allowing an administrator to change the order and
           methods by which server names are looked up.

       password
           The password required to access the specified service on the
           specified server. If this parameter is supplied, the -N option
           (suppress password prompt) is assumed.

           There is no default password. If no password is supplied on the
           command line (either by using this parameter or adding a password
           to the -U option (see below)) and the -N option is not specified,
           the client will prompt for a password, even if the desired service
           does not require one. (If no password is required, simply press
           ENTER to provide a null password.)

           Note: Some servers (including OS/2 and Windows for Workgroups)
           insist on an uppercase password. Lowercase or mixed case passwords
           may be rejected by these servers.

           Be cautious about including passwords in scripts.

       -R <name resolve order>
           This option is used by the programs in the Samba suite to determine
           what naming services and in what order to resolve host names to IP
           addresses. The option takes a space-separated string of different
           name resolution options.

           The options are :"lmhosts", "host", "wins" and "bcast". They cause
           names to be resolved as follows:

           o   lmhosts: Lookup an IP address in the Samba lmhosts file. If the
               line in lmhosts has no name type attached to the NetBIOS name
               (see the lmhosts(5) for details) then any name type matches for
               lookup.

           o   host: Do a standard host name to IP address resolution, using
               the system /etc/hosts , NIS, or DNS lookups. This method of
               name resolution is operating system dependent, for instance on
               IRIX or Solaris this may be controlled by the
               /etc/nsswitch.conf file). Note that this method is only used if
               the NetBIOS name type being queried is the 0x20 (server) name
               type, otherwise it is ignored.

           o   wins: Query a name with the IP address listed in the wins
               server parameter. If no WINS server has been specified this
               method will be ignored.

           o   bcast: Do a broadcast on each of the known local interfaces
               listed in the interfaces parameter. This is the least reliable
               of the name resolution methods as it depends on the target host
               being on a locally connected subnet.

           If this parameter is not set then the name resolve order defined in
           the smb.conf(5) file parameter (name resolve order) will be used.

           The default order is lmhosts, host, wins, bcast and without this
           parameter or any entry in the name resolve order parameter of the
           smb.conf(5) file the name resolution methods will be attempted in
           this order.

       -M NetBIOS name
           This options allows you to send messages, using the "WinPopup"
           protocol, to another computer. Once a connection is established you
           then type your message, pressing ^D (control-D) to end.

           If the receiving computer is running WinPopup the user will receive
           the message and probably a beep. If they are not running WinPopup
           the message will be lost, and no error message will occur.

           The message is also automatically truncated if the message is over
           1600 bytes, as this is the limit of the protocol.

           One useful trick is to pipe the message through smbclient. For
           example: smbclient -M FRED < mymessage.txt will send the message in
           the file mymessage.txt to the machine FRED.

           You may also find the -U and -I options useful, as they allow you
           to control the FROM and TO parts of the message.

           See the message command parameter in the smb.conf(5) for a
           description of how to handle incoming WinPopup messages in Samba.

           Note: Copy WinPopup into the startup group on your WfWg PCs if you
           want them to always be able to receive messages.

       -p port
           This number is the TCP port number that will be used when making
           connections to the server. The standard (well-known) TCP port
           number for an SMB/CIFS server is 139, which is the default.

       -P
           Make queries to the external server using the machine account of
           the local server.

       -h|--help
           Print a summary of command line options.

       -I IP-address
           IP address is the address of the server to connect to. It should be
           specified in standard "a.b.c.d" notation.

           Normally the client would attempt to locate a named SMB/CIFS server
           by looking it up via the NetBIOS name resolution mechanism
           described above in the name resolve order parameter above. Using
           this parameter will force the client to assume that the server is
           on the machine with the specified IP address and the NetBIOS name
           component of the resource being connected to will be ignored.

           There is no default for this parameter. If not supplied, it will be
           determined automatically by the client as described above.

       -E
           This parameter causes the client to write messages to the standard
           error stream (stderr) rather than to the standard output stream.

           By default, the client writes messages to standard output -
           typically the user's tty.

       -L
           This option allows you to look at what services are available on a
           server. You use it as smbclient -L host and a list should appear.
           The -I option may be useful if your NetBIOS names don't match your
           TCP/IP DNS host names or if you are trying to reach a host on
           another network.

       -t terminal code
           This option tells smbclient how to interpret filenames coming from
           the remote server. Usually Asian language multibyte UNIX
           implementations use different character sets than SMB/CIFS servers
           (EUC instead of
            SJIS for example). Setting this parameter will let smbclient
           convert between the UNIX filenames and the SMB filenames correctly.
           This option has not been seriously tested and may have some
           problems.

           The terminal codes include CWsjis, CWeuc, CWjis7, CWjis8, CWjunet,
           CWhex, CWcap. This is not a complete list, check the Samba source
           code for the complete list.

       -b buffersize
           This option changes the transmit/send buffer size when getting or
           putting a file from/to the server. The default is 65520 bytes.
           Setting this value smaller (to 1200 bytes) has been observed to
           speed up file transfers to and from a Win9x server.

       -e
           This command line parameter requires the remote server support the
           UNIX extensions. Request that the connection be encrypted. This is
           new for Samba 3.2 and will only work with Samba 3.2 or above
           servers. Negotiates SMB encryption using GSSAPI. Uses the given
           credentials for the encryption negotiaion (either kerberos or
           NTLMv1/v2 if given domain/username/password triple. Fails the
           connection if encryption cannot be negotiated.

       -d|--debuglevel=level
           level is an integer from 0 to 10. The default value if this
           parameter is not specified is 1.

           The higher this value, the more detail will be logged to the log
           files about the activities of the server. At level 0, only critical
           errors and serious warnings will be logged. Level 1 is a reasonable
           level for day-to-day running - it generates a small amount of
           information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and
           should only be used when investigating a problem. Levels above 3
           are designed for use only by developers and generate HUGE amounts
           of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log
           level parameter in the smb.conf file.

       -V
           Prints the program version number.

       -s <configuration file>
           The file specified contains the configuration details required by
           the server. The information in this file includes server-specific
           information such as what printcap file to use, as well as
           descriptions of all the services that the server is to provide. See
           smb.conf for more information. The default configuration file name
           is determined at compile time.

       -l|--log-basename=logdirectory
           Base directory name for log/debug files. The extension ".progname"
           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
           file is never removed by the client.

       -N
           If specified, this parameter suppresses the normal password prompt
           from the client to the user. This is useful when accessing a
           service that does not require a password.

           Unless a password is specified on the command line or this
           parameter is specified, the client will request a password.

           If a password is specified on the command line and this option is
           also defined the password on the command line will be silently
           ingnored and no password will be used.

       -k
           Try to authenticate with kerberos. Only useful in an Active
           Directory environment.

       -A|--authentication-file=filename
           This option allows you to specify a file from which to read the
           username and password used in the connection. The format of the
           file is

               username = <value>
               password = <value>
               domain   = <value>

           Make certain that the permissions on the file restrict access from
           unwanted users.

       -U|--user=username[%password]
           Sets the SMB username or username and password.

           If %password is not specified, the user will be prompted. The
           client will first check the USER environment variable, then the
           LOGNAME variable and if either exists, the string is uppercased. If
           these environmental variables are not found, the username GUEST is
           used.

           A third option is to use a credentials file which contains the
           plaintext of the username and password. This option is mainly
           provided for scripts where the admin does not wish to pass the
           credentials on the command line or via environment variables. If
           this method is used, make certain that the permissions on the file
           restrict access from unwanted users. See the -A for more details.

           Be cautious about including passwords in scripts. Also, on many
           systems the command line of a running process may be seen via the
           ps command. To be safe always allow rpcclient to prompt for a
           password and type it in directly.

       -n <primary NetBIOS name>
           This option allows you to override the NetBIOS name that Samba uses
           for itself. This is identical to setting the netbios name parameter
           in the smb.conf file. However, a command line setting will take
           precedence over settings in smb.conf.

       -i <scope>
           This specifies a NetBIOS scope that nmblookup will use to
           communicate with when generating NetBIOS names. For details on the
           use of NetBIOS scopes, see rfc1001.txt and rfc1002.txt. NetBIOS
           scopes are very rarely used, only set this parameter if you are the
           system administrator in charge of all the NetBIOS systems you
           communicate with.

       -W|--workgroup=domain
           Set the SMB domain of the username. This overrides the default
           domain which is the domain defined in smb.conf. If the domain
           specified is the same as the servers NetBIOS name, it causes the
           client to log on using the servers local SAM (as opposed to the
           Domain SAM).

       -O socket options
           TCP socket options to set on the client socket. See the socket
           options parameter in the smb.conf manual page for the list of valid
           options.

       -T tar options
           smbclient may be used to create tar(1) compatible backups of all
           the files on an SMB/CIFS share. The secondary tar flags that can be
           given to this option are :

           o   c - Create a tar file on UNIX. Must be followed by the name of
               a tar file, tape device or "-" for standard output. If using
               standard output you must turn the log level to its lowest value
               -d0 to avoid corrupting your tar file. This flag is mutually
               exclusive with the x flag.

           o   x - Extract (restore) a local tar file back to a share. Unless
               the -D option is given, the tar files will be restored from the
               top level of the share. Must be followed by the name of the tar
               file, device or "-" for standard input. Mutually exclusive with
               the c flag. Restored files have their creation times (mtime)
               set to the date saved in the tar file. Directories currently do
               not get their creation dates restored properly.

           o   I - Include files and directories. Is the default behavior when
               filenames are specified above. Causes files to be included in
               an extract or create (and therefore everything else to be
               excluded). See example below. Filename globbing works in one of
               two ways. See r below.

           o   X - Exclude files and directories. Causes files to be excluded
               from an extract or create. See example below. Filename globbing
               works in one of two ways now. See r below.

           o   F - File containing a list of files and directories. The F
               causes the name following the tarfile to create to be read as a
               filename that contains a list of files and directories to be
               included in an extract or create (and therefore everything else
               to be excluded). See example below. Filename globbing works in
               one of two ways. See r below.

           o   b - Blocksize. Must be followed by a valid (greater than zero)
               blocksize. Causes tar file to be written out in
               blocksize*TBLOCK (usually 512 byte) blocks.

           o   g - Incremental. Only back up files that have the archive bit
               set. Useful only with the c flag.

           o   q - Quiet. Keeps tar from printing diagnostics as it works.
               This is the same as tarmode quiet.

           o   r - Regular expression include or exclude. Uses regular
               expression matching for excluding or excluding files if
               compiled with HAVE_REGEX_H. However this mode can be very slow.
               If not compiled with HAVE_REGEX_H, does a limited wildcard
               match on '*' and '?'.

           o   N - Newer than. Must be followed by the name of a file whose
               date is compared against files found on the share during a
               create. Only files newer than the file specified are backed up
               to the tar file. Useful only with the c flag.

           o   a - Set archive bit. Causes the archive bit to be reset when a
               file is backed up. Useful with the g and c flags.

           Tar Long File Names

           smbclient's tar option now supports long file names both on backup
           and restore. However, the full path name of the file must be less
           than 1024 bytes. Also, when a tar archive is created, smbclient's
           tar option places all files in the archive with relative names, not
           absolute names.

           Tar Filenames

           All file names can be given as DOS path names (with '\\' as the
           component separator) or as UNIX path names (with '/' as the
           component separator).

           Examples

           Restore from tar file backup.tar into myshare on mypc (no password
           on share).

           smbclient //mypc/yshare "" -N -Tx backup.tar

           Restore everything except users/docs

           smbclient //mypc/myshare "" -N -TXx backup.tar users/docs

           Create a tar file of the files beneath
            users/docs.

           smbclient //mypc/myshare "" -N -Tc backup.tar users/docs

           Create the same tar file as above, but now use a DOS path name.

           smbclient //mypc/myshare "" -N -tc backup.tar users\edocs

           Create a tar file of the files listed in the file tarlist.

           smbclient //mypc/myshare "" -N -TcF backup.tar tarlist

           Create a tar file of all the files and directories in the share.

           smbclient //mypc/myshare "" -N -Tc backup.tar *

       -D initial directory
           Change to initial directory before starting. Probably only of any
           use with the tar -T option.

       -c command string
           command string is a semicolon-separated list of commands to be
           executed instead of prompting from stdin.
            -N is implied by -c.

           This is particularly useful in scripts and for printing stdin to
           the server, e.g.  -c 'print -'.


OPERATIONS

       Once the client is running, the user is presented with a prompt :

       smb:\>

       The backslash ("\\") indicates the current working directory on the
       server, and will change if the current working directory is changed.

       The prompt indicates that the client is ready and waiting to carry out
       a user command. Each command is a single word, optionally followed by
       parameters specific to that command. Command and parameters are
       space-delimited unless these notes specifically state otherwise. All
       commands are case-insensitive. Parameters to commands may or may not be
       case sensitive, depending on the command.

       You can specify file names which have spaces in them by quoting the
       name with double quotes, for example "a long file name".

       Parameters shown in square brackets (e.g., "[parameter]") are optional.
       If not given, the command will use suitable defaults. Parameters shown
       in angle brackets (e.g., "<parameter>") are required.

       Note that all commands operating on the server are actually performed
       by issuing a request to the server. Thus the behavior may vary from
       server to server, depending on how the server was implemented.

       The commands available are given here in alphabetical order.

       ? [command]
           If command is specified, the ? command will display a brief
           informative message about the specified command. If no command is
           specified, a list of available commands will be displayed.

       ! [shell command]
           If shell command is specified, the ! command will execute a shell
           locally and run the specified shell command. If no command is
           specified, a local shell will be run.

       allinfo file
           The client will request that the server return all known
           information about a file or directory (including streams).

       altname file
           The client will request that the server return the "alternate" name
           (the 8.3 name) for a file or directory.

       archive <number>
           Sets the archive level when operating on files. 0 means ignore the
           archive bit, 1 means only operate on files with this bit set, 2
           means only operate on files with this bit set and reset it after
           operation, 3 means operate on all files and reset it after
           operation. The default is 0.

       blocksize <number>
           Sets the blocksize parameter for a tar operation. The default is
           20. Causes tar file to be written out in blocksize*TBLOCK (normally
           512 byte) units.

       cancel jobid0 [jobid1] ... [jobidN]
           The client will request that the server cancel the printjobs
           identified by the given numeric print job ids.

       case_sensitive
           Toggles the setting of the flag in SMB packets that tells the
           server to treat filenames as case sensitive. Set to OFF by default
           (tells file server to treat filenames as case insensitive). Only
           currently affects Samba 3.0.5 and above file servers with the case
           sensitive parameter set to auto in the smb.conf.

       cd <directory name>
           If "directory name" is specified, the current working directory on
           the server will be changed to the directory specified. This
           operation will fail if for any reason the specified directory is
           inaccessible.

           If no directory name is specified, the current working directory on
           the server will be reported.

       chmod file mode in octal
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server change the UNIX permissions to the given
           octal mode, in standard UNIX format.

       chown file uid gid
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server change the UNIX user and group ownership
           to the given decimal values. Note there is currently no way to
           remotely look up the UNIX uid and gid values for a given name. This
           may be addressed in future versions of the CIFS UNIX extensions.

       close <fileid>
           Closes a file explicitly opened by the open command. Used for
           internal Samba testing purposes.

       del <mask>
           The client will request that the server attempt to delete all files
           matching mask from the current working directory on the server.

       dir <mask>
           A list of the files matching mask in the current working directory
           on the server will be retrieved from the server and displayed.

       du <filename>
           Does a directory listing and then prints out the current disk
           useage and free space on a share.

       echo <number> <data>
           Does an SMBecho request to ping the server. Used for internal Samba
           testing purposes.

       exit
           Terminate the connection with the server and exit from the program.

       get <remote file name> [local file name]
           Copy the file called remote file name from the server to the
           machine running the client. If specified, name the local copy local
           file name. Note that all transfers in smbclient are binary. See
           also the lowercase command.

       getfacl <filename>
           Requires the server support the UNIX extensions. Requests and
           prints the POSIX ACL on a file.

       hardlink <src> <dest<
           Creates a hardlink on the server using Windows CIFS semantics. the
           POSIX ACL on a file.

       help [command]
           See the ? command above.

       history
           Displays the command history.

       iosize <bytes>
           When sending or receiving files, smbclient uses an internal memory
           buffer by default of size 64512 bytes. This command allows this
           size to be set to any range between 16384 (0x4000) bytes and
           16776960 (0xFFFF00) bytes. Larger sizes may mean more efficient
           data transfer as smbclient will try and use the most efficient read
           and write calls for the connected server.

       lcd [directory name]
           If directory name is specified, the current working directory on
           the local machine will be changed to the directory specified. This
           operation will fail if for any reason the specified directory is
           inaccessible.

           If no directory name is specified, the name of the current working
           directory on the local machine will be reported.

       link target linkname
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server create a hard link between the linkname
           and target files. The linkname file must not exist.

       listconnect
           Show the current connections held for DFS purposes.

       lock <filenum> <r|w> <hex-start> <hex-len>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Tries to set a
           POSIX fcntl lock of the given type on the given range. Used for
           internal Samba testing purposes.

       logon <username> <password>
           Establishes a new vuid for this session by logging on again.
           Replaces the current vuid. Prints out the new vuid. Used for
           internal Samba testing purposes.

       lowercase
           Toggle lowercasing of filenames for the get and mget commands.

           When lowercasing is toggled ON, local filenames are converted to
           lowercase when using the get and mget commands. This is often
           useful when copying (say) MSDOS files from a server, because
           lowercase filenames are the norm on UNIX systems.

       ls <mask>
           See the dir command above.

       mask <mask>
           This command allows the user to set up a mask which will be used
           during recursive operation of the mget and mput commands.

           The masks specified to the mget and mput commands act as filters
           for directories rather than files when recursion is toggled ON.

           The mask specified with the mask command is necessary to filter
           files within those directories. For example, if the mask specified
           in an mget command is "source*" and the mask specified with the
           mask command is "*.c" and recursion is toggled ON, the mget command
           will retrieve all files matching "*.c" in all directories below and
           including all directories matching "source*" in the current working
           directory.

           Note that the value for mask defaults to blank (equivalent to "*")
           and remains so until the mask command is used to change it. It
           retains the most recently specified value indefinitely. To avoid
           unexpected results it would be wise to change the value of mask
           back to "*" after using the mget or mput commands.

       md <directory name>
           See the mkdir command.

       mget <mask>
           Copy all files matching mask from the server to the machine running
           the client.

           Note that mask is interpreted differently during recursive
           operation and non-recursive operation - refer to the recurse and
           mask commands for more information. Note that all transfers in
           smbclient are binary. See also the lowercase command.

       mkdir <directory name>
           Create a new directory on the server (user access privileges
           permitting) with the specified name.

       more <file name>
           Fetch a remote file and view it with the contents of your PAGER
           environment variable.

       mput <mask>
           Copy all files matching mask in the current working directory on
           the local machine to the current working directory on the server.

           Note that mask is interpreted differently during recursive
           operation and non-recursive operation - refer to the recurse and
           mask commands for more information. Note that all transfers in
           smbclient are binary.

       posix
           Query the remote server to see if it supports the CIFS UNIX
           extensions and prints out the list of capabilities supported. If
           so, turn on POSIX pathname processing and large file read/writes
           (if available),.

       posix_encrypt <domain> <username> <password>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Attempt to
           negotiate SMB encryption on this connection. If smbclient connected
           with kerberos credentials (-k) the arguments to this command are
           ignored and the kerberos credentials are used to negotiate GSSAPI
           signing and sealing instead. See also the -e option to smbclient to
           force encryption on initial connection. This command is new with
           Samba 3.2.

       posix_open <filename> <octal mode>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Opens a remote
           file using the CIFS UNIX extensions and prints a fileid. Used for
           internal Samba testing purposes.

       posix_mkdir <directoryname> <octal mode>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Creates a remote
           directory using the CIFS UNIX extensions with the given mode.

       posix_rmdir <directoryname>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Deletes a remote
           directory using the CIFS UNIX extensions.

       posix_unlink <filename>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Deletes a remote
           file using the CIFS UNIX extensions.

       print <file name>
           Print the specified file from the local machine through a printable
           service on the server.

       prompt
           Toggle prompting for filenames during operation of the mget and
           mput commands.

           When toggled ON, the user will be prompted to confirm the transfer
           of each file during these commands. When toggled OFF, all specified
           files will be transferred without prompting.

       put <local file name> [remote file name]
           Copy the file called local file name from the machine running the
           client to the server. If specified, name the remote copy remote
           file name. Note that all transfers in smbclient are binary. See
           also the lowercase command.

       queue
           Displays the print queue, showing the job id, name, size and
           current status.

       quit
           See the exit command.

       rd <directory name>
           See the rmdir command.

       recurse
           Toggle directory recursion for the commands mget and mput.

           When toggled ON, these commands will process all directories in the
           source directory (i.e., the directory they are copying from ) and
           will recurse into any that match the mask specified to the command.
           Only files that match the mask specified using the mask command
           will be retrieved. See also the mask command.

           When recursion is toggled OFF, only files from the current working
           directory on the source machine that match the mask specified to
           the mget or mput commands will be copied, and any mask specified
           using the mask command will be ignored.

       rm <mask>
           Remove all files matching mask from the current working directory
           on the server.

       rmdir <directory name>
           Remove the specified directory (user access privileges permitting)
           from the server.

       setmode <filename> <perm=[+|\-]rsha>
           A version of the DOS attrib command to set file permissions. For
           example:

           setmode myfile +r

           would make myfile read only.

       showconnect
           Show the currently active connection held for DFS purposes.

       stat file
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests the UNIX basic info level and prints out the same info
           that the Linux stat command would about the file. This includes the
           size, blocks used on disk, file type, permissions, inode number,
           number of links and finally the three timestamps (access, modify
           and change). If the file is a special file (symlink, character or
           block device, fifo or socket) then extra information may also be
           printed.

       symlink target linkname
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server create a symbolic hard link between the
           target and linkname files. The linkname file must not exist. Note
           that the server will not create a link to any path that lies
           outside the currently connected share. This is enforced by the
           Samba server.

       tar <c|x>[IXbgNa]
           Performs a tar operation - see the -T command line option above.
           Behavior may be affected by the tarmode command (see below). Using
           g (incremental) and N (newer) will affect tarmode settings. Note
           that using the "-" option with tar x may not work - use the command
           line option instead.

       blocksize <blocksize>
           Blocksize. Must be followed by a valid (greater than zero)
           blocksize. Causes tar file to be written out in blocksize*TBLOCK
           (usually 512 byte) blocks.

       tarmode <full|inc|reset|noreset>
           Changes tar's behavior with regard to archive bits. In full mode,
           tar will back up everything regardless of the archive bit setting
           (this is the default mode). In incremental mode, tar will only back
           up files with the archive bit set. In reset mode, tar will reset
           the archive bit on all files it backs up (implies read/write
           share).

       unlock <filenum> <hex-start> <hex-len>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Tries to unlock a
           POSIX fcntl lock on the given range. Used for internal Samba
           testing purposes.

       volume
           Prints the current volume name of the share.

       vuid <number>
           Changes the currently used vuid in the protocol to the given
           arbitrary number. Without an argument prints out the current vuid
           being used. Used for internal Samba testing purposes.


NOTES

       Some servers are fussy about the case of supplied usernames, passwords,
       share names (AKA service names) and machine names. If you fail to
       connect try giving all parameters in uppercase.

       It is often necessary to use the -n option when connecting to some
       types of servers. For example OS/2 LanManager insists on a valid
       NetBIOS name being used, so you need to supply a valid name that would
       be known to the server.

       smbclient supports long file names where the server supports the
       LANMAN2 protocol or above.


ENVIRONMENT VARIABLES

       The variable USER may contain the username of the person using the
       client. This information is used only if the protocol level is high
       enough to support session-level passwords.

       The variable PASSWD may contain the password of the person using the
       client. This information is used only if the protocol level is high
       enough to support session-level passwords.

       The variable LIBSMB_PROG may contain the path, executed with system(),
       which the client should connect to instead of connecting to a server.
       This functionality is primarily intended as a development aid, and
       works best when using a LMHOSTS file


INSTALLATION

       The location of the client program is a matter for individual system
       administrators. The following are thus suggestions only.

       It is recommended that the smbclient software be installed in the
       /usr/local/samba/bin/ or
        /usr/samba/bin/ directory, this directory readable by all, writeable
       only by root. The client program itself should be executable by all.
       The client should NOT be setuid or setgid!

       The client log files should be put in a directory readable and
       writeable only by the user.

       To test the client, you will need to know the name of a running
       SMB/CIFS server. It is possible to run smbd(8) as an ordinary user -
       running that server as a daemon on a user-accessible port (typically
       any port number over 1024) would provide a suitable test server.


DIAGNOSTICS

       Most diagnostics issued by the client are logged in a specified log
       file. The log file name is specified at compile time, but may be
       overridden on the command line.

       The number and nature of diagnostics available depends on the debug
       level used by the client. If you have problems, set the debug level to
       3 and peruse the log files.

AUTHOR

       The original Samba software and related utilities were created by
       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The original Samba man pages were written by Karl Auer. The man page
       sources were converted to YODL format (another excellent piece of Open
       Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and
       updated for the Samba 2.0 release by Jeremy Allison. The conversion to
       DocBook for Samba 2.2 was done by Gerald Carter. The conversion to
       DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
