	<title>DESCRIPTION</title>

	<para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
	<manvolnum>7</manvolnum></citerefentry> suite.</para>

	<para><command>smbclient</command> is a client that can
	'talk' to an SMB/CIFS server. It offers an interface
	similar to that of the ftp program (see <citerefentry><refentrytitle>ftp</refentrytitle>
	<manvolnum>1</manvolnum></citerefentry>).
	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. </para>
</refsect1>


<refsect1>
	<title>OPTIONS</title>

	<variablelist>
		<varlistentry>
		<term>servicename</term>
		<listitem><para>servicename is the name of the service
		you want to use on the server. A service name takes the form
		<filename>//server/service</filename> where <parameter>server
		</parameter> is the NetBIOS name of the SMB/CIFS server
		offering the desired service and <parameter>service</parameter>
		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 <filename>//smbserver/printer
		</filename></para>

		<para>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.
		</para>

		<para>The server name is looked up according to either
		the <parameter>-R|--name-resolve</parameter> parameter to <command>smbclient</command> or
		using the name resolve order parameter in
		the <citerefentry><refentrytitle>smb.conf</refentrytitle>
		<manvolnum>5</manvolnum></citerefentry> file,
		allowing an administrator to change the order and methods
		by which server names are looked up. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>password</term>
		<listitem><para>The password required to access the specified
		service on the specified server. If this parameter is
		supplied, the <parameter>-N</parameter> option (suppress
		password prompt) is assumed. </para>

		<para>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 <parameter>-U</parameter> option (see
		below)) and the <parameter>-N</parameter> 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.)
		</para>

		<para>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.
		</para>

		<para>Be cautious about including passwords in scripts.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-M|--message NetBIOS name</term>
		<listitem><para>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. </para>

		<para>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. </para>

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

		<para>
		One useful trick is to pipe the message through <command>smbclient</command>.
		For example: smbclient -M FRED &lt; mymessage.txt will send the
		message in the file <filename>mymessage.txt</filename> to the
		machine FRED.
		</para>

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

		<para>See the <parameter>message command</parameter> parameter in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
		<manvolnum>5</manvolnum></citerefentry> for a description of how to handle incoming
		WinPopup messages in Samba. </para>

		<para><emphasis>Note</emphasis>: Copy WinPopup into the startup group
		on your WfWg PCs if you want them to always be able to receive
		messages. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-p|--port port</term>
		<listitem><para>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. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-g|--grepable</term>
		<listitem><para>This parameter provides combined with
		<parameter>-L</parameter> easy parseable output	that allows processing
		with utilities such as grep and cut.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-m|--max-protocol protocol</term>
		<listitem><para>This allows the user to select the
		highest SMB protocol level that smbclient will use to
		connect to the server. By default this is set to
		highest available SMB3 protocol version.
		To connect using SMB2 or SMB1 protocol, use the
		strings SMB2 or NT1 respectively. Note that to connect
		to a Windows 2012 server with encrypted transport selecting
		a max-protocol of SMB3 is required.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-P|--machine-pass</term>
		<listitem><para>
		Make queries to the external server using the machine account of the local server.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-I|--ip-address IP-address</term>
		<listitem><para><replaceable>IP address</replaceable> is the address of the server to connect to.
		It should be specified in standard "a.b.c.d" notation. </para>

		<para>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 <parameter>name resolve order</parameter>
		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. </para>

		<para>There is no default for this parameter. If not supplied,
		it will be determined automatically by the client as described
		above. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-E|--stderr</term>
		<listitem><para>This parameter causes the client to write messages
		to the standard error stream (stderr) rather than to the standard
		output stream. </para>

		<para>By default, the client writes messages to standard output
		- typically the user's tty. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-L|--list</term>
		<listitem><para>This option allows you to look at what services
		are available on a server. You use it as <command>smbclient -L
		host</command> and a list should appear.  The <parameter>-I
		</parameter> 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. </para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-b|--send-buffer buffersize</term>
		<listitem><para>
		When sending or receiving files, smbclient uses an
		internal buffer sized by the maximum number of allowed requests
		to the connected server. This command allows this size to be set to any
		range between 0 (which means use the default server controlled size) bytes
		and 16776960 (0xFFFF00) bytes. Using the server controlled size is the
		most efficient as smbclient will pipeline as many simultaneous reads or
		writes needed to keep the server as busy as possible. Setting this to
		any other size will slow down the transfer. This can also be set
		using the <command>iosize</command> command inside smbclient.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-B|--browse</term>
		<listitem><para>Browse SMB servers using DNS.</para>
		</listitem>
		</varlistentry>

		<varlistentry>
		<term>-t|--timeout &lt;timeout-seconds&gt;</term>
		<listitem><para>This allows the user to tune the default
		timeout used for each SMB request. The default setting is
		20 seconds. Increase it if requests to the server sometimes
		time out. This can happen when SMB3 encryption is selected
		and smbclient is overwhelming the server with requests.
		This can also be set using the <command>timeout</command>
		command inside smbclient.
		</para></listitem>
		</varlistentry>

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

		<itemizedlist>
			<listitem><para><parameter>c</parameter> - Create a tar
			backup archive on the local system.	 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
			<parameter>x</parameter> flag. </para></listitem>

			<listitem><para><parameter>n</parameter> - In
			combination with the <parameter>c</parameter>
			flag, do not actually create the archive,
			instead perform a dry run that attempts
			everything that involved in creation other than
			writing the file.</para></listitem>

			<listitem><para><parameter>x</parameter> - 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 <parameter>c</parameter> 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. </para></listitem>

			<listitem><para><parameter>I</parameter> - 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 <parameter>r</parameter> below. </para></listitem>

			<listitem><para><parameter>X</parameter> - 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.
			See <parameter>r</parameter> below. </para></listitem>

			<listitem><para><parameter>F</parameter> - File containing a list of files and directories.
			The <parameter>F</parameter> 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 <parameter>r</parameter> below.
			</para></listitem>

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

			<listitem><para><parameter>g</parameter> - Incremental. Only back up
			files that have the archive bit set. Useful only with the
			<parameter>c</parameter> flag. </para></listitem>

			<listitem><para><parameter>v</parameter> - Verbose. Makes tar
			print out the files being processed. By default tar is not verbose.
			This is the same as tarmode verbose.
			</para></listitem>

			<listitem><para><parameter>r</parameter> - Use wildcard
			matching to include or exclude. Deprecated.
			</para></listitem>

			<listitem><para><parameter>N</parameter> - 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
			<parameter>c</parameter> flag. </para></listitem>

			<listitem><para><parameter>a</parameter> - Set archive bit. Causes the
			archive bit to be reset when a file is backed up. Useful with the
			<parameter>g</parameter> and <parameter>c</parameter> flags.
			</para></listitem>

		</itemizedlist>

		<para><emphasis>Tar Long File Names</emphasis></para>

		<para><command>smbclient</command>'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, <command>smbclient</command>'s tar option places all
		files in the archive with relative names, not absolute names.
		</para>

		<para><emphasis>Tar Filenames</emphasis></para>

		<para>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). </para>

		<para><emphasis>Examples</emphasis></para>

		<para>Restore from tar file <filename>backup.tar</filename> into myshare on mypc
		(no password on share). </para>

		<para><command>smbclient //mypc/myshare "" -N -Tx backup.tar

	<title>OPERATIONS</title>

	<para>Once the client is running, the user is presented with
	a prompt : </para>

	<para><prompt>smb:\&gt; </prompt></para>

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

	<para>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.
	</para>

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

	<para>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., "&lt;parameter&gt;") are required.
	</para>


	<para>Note that all commands operating on the server are actually
	performed by issuing a request to the server. Thus the behavior may

		<term>iosize &lt;bytes&gt;</term>
		<listitem><para>
		When sending or receiving files, smbclient uses an
		internal buffer sized by the maximum number of allowed requests
		to the connected server. This command allows this size to be set to any
		range between 0 (which means use the default server controlled size) bytes
		and 16776960 (0xFFFF00) bytes. Using the server controlled size is the
		most efficient as smbclient will pipeline as many simultaneous reads or
		writes needed to keep the server as busy as possible. Setting this to
		any other size will slow down the transfer.

	<title>INSTALLATION</title>

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

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

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

	<para>To test the client, you will need to know the name of a
	running SMB/CIFS server. It is possible to run <citerefentry><refentrytitle>smbd</refentrytitle>
	<manvolnum>8</manvolnum></citerefentry> 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. </para>
</refsect1>


<refsect1>
	<title>DIAGNOSTICS</title>

	<para>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. </para>

	<para>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. </para>
