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 
           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.

        g
           This parameter provides combined with  L easy parseable output that
           allows processing with utilities such as grep and cut.

        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
           smb.conf.5.html
