smbclient(1) - ftp-like client to access SMB/CIFS resources on servers
-R|--name-resolve <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.
-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.
-p|--port 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|--grepable
    This parameter provides combined with -L easy parseable output that allows processing with utilities
    such as grep and cut.
-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
    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# 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
-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|--netbiosname <primary NetBIOS name>
    This option allows you to override the NetBIOS name that Samba uses for itself. This is identical to
    setting the smb.conf.5.html# 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 :
-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.
