    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
               The options are :"lmhosts", "host", "wins" and "bcast". They cause
               names to be resolved as follows:
    
               ?   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.
    
               ?   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.
    
               ?   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.
    
               ?   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|--message 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.
    
    
           -m|--max-protocol protocol
               This parameter sets the maximum protocol version announced by the
               client.
    
           -P|--machine-pass
               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
               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|--stderr
               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|--list
               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.
    
           -b|--send-buffer 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|--encrypt
               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 negotiation (either kerberos or
               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|--version
               Prints the program version number.
    
           -s|--configfile <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|--no-pass
               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|--kerberos
               Try to authenticate with kerberos. Only useful in an Active
               Directory environment.
    
           -C|--use-ccache
               Try to use the credentials cached by winbind.
    
           -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
               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|--netbiosname <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 <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 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 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 :
    
               ?   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.
    
               ?   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
                   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.
    
               ?   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.
    
               ?   g - Incremental. Only back up files that have the archive bit
                   set. Useful only with the c flag.
    
               ?   q - Quiet. Keeps tar from printing diagnostics as it works.
                   This is the same as tarmode quiet.
    
               ?   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 '?'.
    
               ?   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.
    
               ?   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/myshare "" -N -Tx backup.tar
    
           Restore everything except users/docs
    
           Create a tar file of all the files and directories in the share.
    
           smbclient //mypc/myshare "" -N -Tc backup.tar *
    
           -D|--directory initial directory
               Change to initial directory before starting. Probably only of any
               use with the tar -T option.
    
           -c|--command 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
               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
               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.
    
           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.
    
           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
    
           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.
    
           readlink symlinkname
               This command depends on the server supporting the CIFS UNIX
               extensions and will fail if the server does not. Print the value of
               the symlink "symlinkname".
    
           rd <directory name>
               using the mask command will be ignored.
    
           rename <old filename> <new filename>
               Rename files in the current working directory on the server from
               old filename to new filename.
    
           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.
    
               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.
    
    
    

    VERSION

           This man page is correct for version 3.2 of the Samba suite.
    
    
    

    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.
