80 <para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
81 <manvolnum>7</manvolnum></citerefentry> suite.</para>
83 <para><command>smbclient</command> is a client that can
84 'talk' to an SMB/CIFS server. It offers an interface
85 similar to that of the ftp program (see <citerefentry><refentrytitle>ftp</refentrytitle>
86 <manvolnum>1</manvolnum></citerefentry>).
87 Operations include things like getting files from the server
88 to the local machine, putting files from the local machine to
89 the server, retrieving directory information from the server
95 <title>OPTIONS</title>
99 <term>servicename</term>
100 <listitem><para>servicename is the name of the service
101 you want to use on the server. A service name takes the form
102 <filename>//server/service</filename> where <parameter>server
103 </parameter> is the NetBIOS name of the SMB/CIFS server
104 offering the desired service and <parameter>service</parameter>
105 is the name of the service offered. Thus to connect to
106 the service "printer" on the SMB/CIFS server "smbserver",
107 you would use the servicename <filename>//smbserver/printer
110 <para>Note that the server name required is NOT necessarily
111 the IP (DNS) host name of the server ! The name required is
112 a NetBIOS server name, which may or may not be the
113 same as the IP hostname of the machine running the server.
116 <para>The server name is looked up according to either
117 the <parameter>-R</parameter> parameter to <command>smbclient</command> or
118 using the name resolve order parameter in
119 the <citerefentry><refentrytitle>smb.conf</refentrytitle>
120 <manvolnum>5</manvolnum></citerefentry> file,
121 allowing an administrator to change the order and methods
122 by which server names are looked up. </para></listitem>
126 <term>password</term>
127 <listitem><para>The password required to access the specified
128 service on the specified server. If this parameter is
129 supplied, the <parameter>-N</parameter> option (suppress
130 password prompt) is assumed. </para>
132 <para>There is no default password. If no password is supplied
133 on the command line (either by using this parameter or adding
134 a password to the <parameter>-U</parameter> option (see
135 below)) and the <parameter>-N</parameter> option is not
136 specified, the client will prompt for a password, even if
137 the desired service does not require one. (If no password is
138 required, simply press ENTER to provide a null password.)
141 <para>Note: Some servers (including OS/2 and Windows for
142 Workgroups) insist on an uppercase password. Lowercase
143 or mixed case passwords may be rejected by these servers.
146 <para>Be cautious about including passwords in scripts.
151 <term>-R|--name-resolve <name resolve order></term>
152 <listitem><para>This option is used by the programs in the Samba
153 suite to determine what naming services and in what order to resolve
154 host names to IP addresses. The option takes a space-separated
155 string of different name resolution options.</para>
157 <para>The options are :"lmhosts", "host", "wins" and "bcast". They
158 cause names to be resolved as follows:</para>
161 <listitem><para><constant>lmhosts</constant>: Lookup an IP
162 address in the Samba lmhosts file. If the line in lmhosts has
163 no name type attached to the NetBIOS name (see
164 the <citerefentry><refentrytitle>lmhosts</refentrytitle>
165 <manvolnum>5</manvolnum></citerefentry> for details) then
166 any name type matches for lookup.</para>
169 <listitem><para><constant>host</constant>: Do a standard host
170 name to IP address resolution, using the system <filename>/etc/hosts
171 </filename>, NIS, or DNS lookups. This method of name resolution
172 is operating system dependent, for instance on IRIX or Solaris this
173 may be controlled by the <filename>/etc/nsswitch.conf</filename>
174 file). Note that this method is only used if the NetBIOS name
175 type being queried is the 0x20 (server) name type, otherwise
176 it is ignored.</para>
179 <listitem><para><constant>wins</constant>: Query a name with
180 the IP address listed in the <parameter>wins server</parameter>
181 parameter. If no WINS server has
182 been specified this method will be ignored.</para>
185 <listitem><para><constant>bcast</constant>: Do a broadcast on
186 each of the known local interfaces listed in the
187 <parameter>interfaces</parameter>
188 parameter. This is the least reliable of the name resolution
189 methods as it depends on the target host being on a locally
190 connected subnet.</para>
194 <para>If this parameter is not set then the name resolve order
195 defined in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
196 <manvolnum>5</manvolnum></citerefentry> file parameter
197 (name resolve order) will be used. </para>
199 <para>The default order is lmhosts, host, wins, bcast and without
200 this parameter or any entry in the <parameter>name resolve order
201 </parameter> parameter of the <citerefentry><refentrytitle>smb.conf</refentrytitle>
202 <manvolnum>5</manvolnum></citerefentry> file the name resolution
203 methods will be attempted in this order. </para></listitem>
208 <term>-M|--message NetBIOS name</term>
209 <listitem><para>This options allows you to send messages, using
210 the "WinPopup" protocol, to another computer. Once a connection is
211 established you then type your message, pressing ^D (control-D) to
214 <para>If the receiving computer is running WinPopup the user will
215 receive the message and probably a beep. If they are not running
216 WinPopup the message will be lost, and no error message will
219 <para>The message is also automatically truncated if the message
220 is over 1600 bytes, as this is the limit of the protocol.
224 One useful trick is to pipe the message through <command>smbclient</command>.
225 For example: smbclient -M FRED < mymessage.txt will send the
226 message in the file <filename>mymessage.txt</filename> to the
230 <para>You may also find the <parameter>-U</parameter> and
231 <parameter>-I</parameter> options useful, as they allow you to
232 control the FROM and TO parts of the message. </para>
234 <para>See the <parameter>message command</parameter> parameter in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
235 <manvolnum>5</manvolnum></citerefentry> for a description of how to handle incoming
236 WinPopup messages in Samba. </para>
238 <para><emphasis>Note</emphasis>: Copy WinPopup into the startup group
239 on your WfWg PCs if you want them to always be able to receive
240 messages. </para></listitem>
244 <term>-p|--port port</term>
245 <listitem><para>This number is the TCP port number that will be used
246 when making connections to the server. The standard (well-known)
247 TCP port number for an SMB/CIFS server is 139, which is the
248 default. </para></listitem>
252 <term>-g|--grepable</term>
253 <listitem><para>This parameter provides combined with
254 <parameter>-L</parameter> easy parseable output that allows processing
255 with utilities such as grep and cut.
260 <term>-m|--max-protocol protocol</term>
261 <listitem><para>This allows the user to select the
262 highest SMB protocol level that smbclient will use to
263 connect to the server. By default this is set to
264 NT1, which is the highest available SMB1 protocol.
265 To connect using SMB2 or SMB3 protocol, use the
266 strings SMB2 or SMB3 respectively. Note that to connect
267 to a Windows 2012 server with encrypted transport selecting
268 a max-protocol of SMB3 is required.
273 <term>-P|--machine-pass</term>
275 Make queries to the external server using the machine account of the local server.
282 <term>-I|--ip-address IP-address</term>
283 <listitem><para><replaceable>IP address</replaceable> is the address of the server to connect to.
284 It should be specified in standard "a.b.c.d" notation. </para>
286 <para>Normally the client would attempt to locate a named
287 SMB/CIFS server by looking it up via the NetBIOS name resolution
288 mechanism described above in the <parameter>name resolve order</parameter>
289 parameter above. Using this parameter will force the client
290 to assume that the server is on the machine with the specified IP
291 address and the NetBIOS name component of the resource being
292 connected to will be ignored. </para>
294 <para>There is no default for this parameter. If not supplied,
295 it will be determined automatically by the client as described
296 above. </para></listitem>
300 <term>-E|--stderr</term>
301 <listitem><para>This parameter causes the client to write messages
302 to the standard error stream (stderr) rather than to the standard
303 output stream. </para>
305 <para>By default, the client writes messages to standard output
306 - typically the user's tty. </para></listitem>
310 <term>-L|--list</term>
311 <listitem><para>This option allows you to look at what services
312 are available on a server. You use it as <command>smbclient -L
313 host</command> and a list should appear. The <parameter>-I
314 </parameter> option may be useful if your NetBIOS names don't
315 match your TCP/IP DNS host names or if you are trying to reach a
316 host on another network. </para></listitem>
320 <term>-b|--send-buffer buffersize</term>
322 When sending or receiving files, smbclient uses an
323 internal buffer sized by the maximum number of allowed requests
324 to the connected server. This command allows this size to be set to any
325 range between 0 (which means use the default server controlled size) bytes
326 and 16776960 (0xFFFF00) bytes. Using the server controlled size is the
327 most efficient as smbclient will pipeline as many simultaneous reads or
328 writes needed to keep the server as busy as possible. Setting this to
329 any other size will slow down the transfer. This can also be set
330 using the <command>iosize</command> command inside smbclient.
335 <term>-e|--encrypt</term>
337 This command line parameter requires the remote
338 server support the UNIX extensions or that the SMB3 protocol has been selected.
339 Requests that the connection be encrypted. Negotiates SMB encryption using either
340 SMB3 or POSIX extensions via GSSAPI. Uses the given credentials for
341 the encryption negotiation (either kerberos or NTLMv1/v2 if given
342 domain/username/password triple. Fails the connection if encryption
343 cannot be negotiated.
347 &stdarg.client.debug;
349 &popt.common.credentials;
350 &popt.common.connection;
353 <term>-t|--timeout <timeout-seconds></term>
354 <listitem><para>This allows the user to tune the default
355 timeout used for each SMB request. The default setting is
356 20 seconds. Increase it if requests to the server sometimes
357 time out. This can happen when SMB3 encryption is selected
358 and smbclient is overwhelming the server with requests.
359 This can also be set using the <command>timeout</command>
360 command inside smbclient.
365 <term>-T|--tar tar options</term>
366 <listitem><para>smbclient may be used to create <command>tar(1)
367 </command> compatible backups of all the files on an SMB/CIFS
368 share. The secondary tar flags that can be given to this option
372 <listitem><para><parameter>c</parameter> - Create a tar file on UNIX.
373 Must be followed by the name of a tar file, tape device
374 or "-" for standard output. If using standard output you must
375 turn the log level to its lowest value -d0 to avoid corrupting
376 your tar file. This flag is mutually exclusive with the
377 <parameter>x</parameter> flag. </para></listitem>
379 <listitem><para><parameter>x</parameter> - Extract (restore) a local
380 tar file back to a share. Unless the -D option is given, the tar
381 files will be restored from the top level of the share. Must be
382 followed by the name of the tar file, device or "-" for standard
383 input. Mutually exclusive with the <parameter>c</parameter> flag.
384 Restored files have their creation times (mtime) set to the
385 date saved in the tar file. Directories currently do not get
386 their creation dates restored properly. </para></listitem>
388 <listitem><para><parameter>I</parameter> - Include files and directories.
389 Is the default behavior when filenames are specified above. Causes
390 files to be included in an extract or create (and therefore
391 everything else to be excluded). See example below. Filename globbing
392 works in one of two ways. See <parameter>r</parameter> below. </para></listitem>
394 <listitem><para><parameter>X</parameter> - Exclude files and directories.
395 Causes files to be excluded from an extract or create. See
396 example below. Filename globbing works in one of two ways now.
397 See <parameter>r</parameter> below. </para></listitem>
399 <listitem><para><parameter>F</parameter> - File containing a list of files and directories.
400 The <parameter>F</parameter> causes the name following the tarfile to
401 create to be read as a filename that contains a list of files and directories to
402 be included in an extract or create (and therefore everything else to be excluded).
403 See example below. Filename globbing works in one of two ways.
404 See <parameter>r</parameter> below.
407 <listitem><para><parameter>b</parameter> - Blocksize. Must be followed
408 by a valid (greater than zero) blocksize. Causes tar file to be
409 written out in blocksize*TBLOCK (usually 512 byte) blocks.
412 <listitem><para><parameter>g</parameter> - Incremental. Only back up
413 files that have the archive bit set. Useful only with the
414 <parameter>c</parameter> flag. </para></listitem>
416 <listitem><para><parameter>q</parameter> - Quiet. Keeps tar from printing
417 diagnostics as it works. This is the same as tarmode quiet.
420 <listitem><para><parameter>r</parameter> - Regular expression include
421 or exclude. Uses regular expression matching for
422 excluding or excluding files if compiled with HAVE_REGEX_H.
423 However this mode can be very slow. If not compiled with
424 HAVE_REGEX_H, does a limited wildcard match on '*' and '?'.
427 <listitem><para><parameter>N</parameter> - Newer than. Must be followed
428 by the name of a file whose date is compared against files found
429 on the share during a create. Only files newer than the file
430 specified are backed up to the tar file. Useful only with the
431 <parameter>c</parameter> flag. </para></listitem>
433 <listitem><para><parameter>a</parameter> - Set archive bit. Causes the
434 archive bit to be reset when a file is backed up. Useful with the
435 <parameter>g</parameter> and <parameter>c</parameter> flags.
439 <para><emphasis>Tar Long File Names</emphasis></para>
441 <para><command>smbclient</command>'s tar option now supports long
442 file names both on backup and restore. However, the full path
443 name of the file must be less than 1024 bytes. Also, when
444 a tar archive is created, <command>smbclient</command>'s tar option places all
445 files in the archive with relative names, not absolute names.
448 <para><emphasis>Tar Filenames</emphasis></para>
450 <para>All file names can be given as DOS path names (with '\\'
451 as the component separator) or as UNIX path names (with '/' as
452 the component separator). </para>

495 <listitem><para>Change to initial directory before starting. Probably
496 only of any use with the tar -T option. </para></listitem>
500 <term>-c|--command command string</term>
501 <listitem><para>command string is a semicolon-separated list of
502 commands to be executed instead of prompting from stdin. <parameter>

521 <para>The backslash ("\\") indicates the current working directory
522 on the server, and will change if the current working directory
525 <para>The prompt indicates that the client is ready and waiting to
526 carry out a user command. Each command is a single word, optionally
527 followed by parameters specific to that command. Command and parameters
528 are space-delimited unless these notes specifically
529 state otherwise. All commands are case-insensitive. Parameters to
530 commands may or may not be case sensitive, depending on the command.
533 <para>You can specify file names which have spaces in them by quoting
534 the name with double quotes, for example "a long file name". </para>
536 <para>Parameters shown in square brackets (e.g., "[parameter]") are
537 optional. If not given, the command will use suitable defaults. Parameters
538 shown in angle brackets (e.g., "<parameter>") are required.
542 <para>Note that all commands operating on the server are actually
543 performed by issuing a request to the server. Thus the behavior may
544 vary from server to server, depending on how the server was implemented.
547 <para>The commands available are given here in alphabetical order. </para>
551 <term>? [command]</term>
552 <listitem><para>If <replaceable>command</replaceable> is specified, the ? command will display
553 a brief informative message about the specified command. If no
554 command is specified, a list of available commands will
555 be displayed. </para></listitem>
559 <term>! [shell command]</term>
560 <listitem><para>If <replaceable>shell command</replaceable> is specified, the !
561 command will execute a shell locally and run the specified shell
562 command. If no command is specified, a local shell will be run.
567 <term>allinfo file</term>
568 <listitem><para>The client will request that the server return
569 all known information about a file or directory (including streams).
574 <term>altname file</term>
575 <listitem><para>The client will request that the server return
576 the "alternate" name (the 8.3 name) for a file or directory.
581 <term>archive <number></term>
582 <listitem><para>Sets the archive level when operating on files.
583 0 means ignore the archive bit, 1 means only operate on files with this bit set,
584 2 means only operate on files with this bit set and reset it after operation,
585 3 means operate on all files and reset it after operation. The default is 0.
591 <listitem><para>Toggle the state of the "backup intent" flag
592 sent to the server on directory listings and file opens. If
593 the "backup intent" flag is true, the server will try and
594 bypass some file system checks if the user has been granted
595 SE_BACKUP or SE_RESTORE privileges. This state is useful when
596 performing a backup or restore operation.
601 <term>blocksize <number></term>
602 <listitem><para>Sets the blocksize parameter for a tar operation. The default is 20.
603 Causes tar file to be written out in blocksize*TBLOCK (normally 512 byte) units.
608 <term>cancel jobid0 [jobid1] ... [jobidN]</term>
609 <listitem><para>The client will request that the server cancel
610 the printjobs identified by the given numeric print job ids.

616 <listitem><para>Toggles the setting of the flag in SMB packets that
617 tells the server to treat filenames as case sensitive. Set to OFF by
618 default (tells file server to treat filenames as case insensitive). Only
619 currently affects Samba 3.0.5 and above file servers with the case sensitive

636 <term>chmod file mode in octal</term>
637 <listitem><para>This command depends on the server supporting the CIFS
638 UNIX extensions and will fail if the server does not. The client requests that the server
639 change the UNIX permissions to the given octal mode, in standard UNIX format.
644 <term>chown file uid gid</term>
645 <listitem><para>This command depends on the server supporting the CIFS

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

1134 <title>NOTES</title>
1136 <para>Some servers are fussy about the case of supplied usernames,
1137 passwords, share names (AKA service names) and machine names.
1138 If you fail to connect try giving all parameters in uppercase.
1141 <para>It is often necessary to use the -n option when connecting
1142 to some types of servers. For example OS/2 LanManager insists
1143 on a valid NetBIOS name being used, so you need to supply a valid
1144 name that would be known to the server.</para>
1146 <para>smbclient supports long file names where the server
1147 supports the LANMAN2 protocol or above. </para>
1151 <title>ENVIRONMENT VARIABLES</title>
1153 <para>The variable <envar>USER</envar> may contain the
1154 username of the person using the client. This information is
1155 used only if the protocol level is high enough to support
1156 session-level passwords.</para>
1159 <para>The variable <envar>PASSWD</envar> may contain
1160 the password of the person using the client. This information is
1161 used only if the protocol level is high enough to support
1162 session-level passwords. </para>
1164 <para>The variable <envar>LIBSMB_PROG</envar> may contain
1165 the path, executed with system(), which the client should connect
1166 to instead of connecting to a server. This functionality is primarily
1167 intended as a development aid, and works best when using a LMHOSTS
1173 <title>INSTALLATION</title>
1175 <para>The location of the client program is a matter for
1176 individual system administrators. The following are thus
1177 suggestions only. </para>
1179 <para>It is recommended that the smbclient software be installed
1180 in the <filename>/usr/local/samba/bin/</filename> or <filename>
1181 /usr/samba/bin/</filename> directory, this directory readable
1182 by all, writeable only by root. The client program itself should
1183 be executable by all. The client should <emphasis>NOT</emphasis> be
1184 setuid or setgid! </para>
1186 <para>The client log files should be put in a directory readable
1187 and writeable only by the user. </para>
1189 <para>To test the client, you will need to know the name of a
1190 running SMB/CIFS server. It is possible to run <citerefentry><refentrytitle>smbd</refentrytitle>
1191 <manvolnum>8</manvolnum></citerefentry> as an ordinary user - running that server as a daemon
1192 on a user-accessible port (typically any port number over 1024)
1193 would provide a suitable test server. </para>
1198 <title>DIAGNOSTICS</title>
1200 <para>Most diagnostics issued by the client are logged in a
