78 <title>DESCRIPTION</title>
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.
280 <term>-I|--ip-address IP-address</term>
281 <listitem><para><replaceable>IP address</replaceable> is the address of the server to connect to.
282 It should be specified in standard "a.b.c.d" notation. </para>
284 <para>Normally the client would attempt to locate a named
285 SMB/CIFS server by looking it up via the NetBIOS name resolution
286 mechanism described above in the <parameter>name resolve order</parameter>
287 parameter above. Using this parameter will force the client
288 to assume that the server is on the machine with the specified IP
289 address and the NetBIOS name component of the resource being
290 connected to will be ignored. </para>
292 <para>There is no default for this parameter. If not supplied,
293 it will be determined automatically by the client as described
294 above. </para></listitem>
298 <term>-E|--stderr</term>
299 <listitem><para>This parameter causes the client to write messages
300 to the standard error stream (stderr) rather than to the standard
301 output stream. </para>
303 <para>By default, the client writes messages to standard output
304 - typically the user's tty. </para></listitem>
308 <term>-L|--list</term>
309 <listitem><para>This option allows you to look at what services
310 are available on a server. You use it as <command>smbclient -L
311 host</command> and a list should appear. The <parameter>-I
312 </parameter> option may be useful if your NetBIOS names don't
313 match your TCP/IP DNS host names or if you are trying to reach a
314 host on another network. </para></listitem>
318 <term>-b|--send-buffer buffersize</term>
320 When sending or receiving files, smbclient uses an
321 internal buffer sized by the maximum number of allowed requests
322 to the connected server. This command allows this size to be set to any
323 range between 0 (which means use the default server controlled size) bytes
324 and 16776960 (0xFFFF00) bytes. Using the server controlled size is the
325 most efficient as smbclient will pipeline as many simultaneous reads or
326 writes needed to keep the server as busy as possible. Setting this to
327 any other size will slow down the transfer. This can also be set
328 using the <command>iosize</command> command inside smbclient.
333 <term>-B|--browse</term>
334 <listitem><para>Browse SMB servers using DNS.</para>
338 &stdarg.client.debug;
340 &popt.common.credentials;
341 &popt.common.connection;
345 <term>-t|--timeout <timeout-seconds></term>
346 <listitem><para>This allows the user to tune the default
347 timeout used for each SMB request. The default setting is
348 20 seconds. Increase it if requests to the server sometimes
349 time out. This can happen when SMB3 encryption is selected
350 and smbclient is overwhelming the server with requests.
351 This can also be set using the <command>timeout</command>
352 command inside smbclient.
357 <term>-T|--tar tar options</term>
358 <listitem><para>smbclient may be used to create <command>tar(1)
359 </command> compatible backups of all the files on an SMB/CIFS
360 share. The secondary tar flags that can be given to this option
364 <listitem><para><parameter>c</parameter> - Create a tar file on UNIX.
365 Must be followed by the name of a tar file, tape device
366 or "-" for standard output. If using standard output you must
367 turn the log level to its lowest value -d0 to avoid corrupting
368 your tar file. This flag is mutually exclusive with the
369 <parameter>x</parameter> flag. </para></listitem>
371 <listitem><para><parameter>x</parameter> - Extract (restore) a local
372 tar file back to a share. Unless the -D option is given, the tar
373 files will be restored from the top level of the share. Must be
374 followed by the name of the tar file, device or "-" for standard
375 input. Mutually exclusive with the <parameter>c</parameter> flag.
376 Restored files have their creation times (mtime) set to the
377 date saved in the tar file. Directories currently do not get
378 their creation dates restored properly. </para></listitem>
380 <listitem><para><parameter>I</parameter> - Include files and directories.
381 Is the default behavior when filenames are specified above. Causes
382 files to be included in an extract or create (and therefore
383 everything else to be excluded). See example below. Filename globbing
384 works in one of two ways. See <parameter>r</parameter> below. </para></listitem>
386 <listitem><para><parameter>X</parameter> - Exclude files and directories.
387 Causes files to be excluded from an extract or create. See
388 example below. Filename globbing works in one of two ways now.
389 See <parameter>r</parameter> below. </para></listitem>
391 <listitem><para><parameter>F</parameter> - File containing a list of files and directories.
392 The <parameter>F</parameter> causes the name following the tarfile to
393 create to be read as a filename that contains a list of files and directories to
394 be included in an extract or create (and therefore everything else to be excluded).
395 See example below. Filename globbing works in one of two ways.
396 See <parameter>r</parameter> below.
399 <listitem><para><parameter>b</parameter> - Blocksize. Must be followed
400 by a valid (greater than zero) blocksize. Causes tar file to be
401 written out in blocksize*TBLOCK (usually 512 byte) blocks.
404 <listitem><para><parameter>g</parameter> - Incremental. Only back up
405 files that have the archive bit set. Useful only with the
406 <parameter>c</parameter> flag. </para></listitem>
408 <listitem><para><parameter>q</parameter> - Quiet. Keeps tar from printing
409 diagnostics as it works. This is the same as tarmode quiet.
412 <listitem><para><parameter>r</parameter> - Regular expression include
413 or exclude. Uses regular expression matching for
414 excluding or excluding files if compiled with HAVE_REGEX_H.
415 However this mode can be very slow. If not compiled with
416 HAVE_REGEX_H, does a limited wildcard match on '*' and '?'.
419 <listitem><para><parameter>N</parameter> - Newer than. Must be followed
420 by the name of a file whose date is compared against files found
421 on the share during a create. Only files newer than the file
422 specified are backed up to the tar file. Useful only with the
423 <parameter>c</parameter> flag. </para></listitem>
425 <listitem><para><parameter>a</parameter> - Set archive bit. Causes the
426 archive bit to be reset when a file is backed up. Useful with the
427 <parameter>g</parameter> and <parameter>c</parameter> flags.
431 <para><emphasis>Tar Long File Names</emphasis></para>
433 <para><command>smbclient</command>'s tar option now supports long
434 file names both on backup and restore. However, the full path
435 name of the file must be less than 1024 bytes. Also, when
436 a tar archive is created, <command>smbclient</command>'s tar option places all
437 files in the archive with relative names, not absolute names.
440 <para><emphasis>Tar Filenames</emphasis></para>
442 <para>All file names can be given as DOS path names (with '\\'
443 as the component separator) or as UNIX path names (with '/' as
444 the component separator). </para>

487 <listitem><para>Change to initial directory before starting. Probably
488 only of any use with the tar -T option. </para></listitem>
492 <term>-c|--command command string</term>
493 <listitem><para>command string is a semicolon-separated list of
494 commands to be executed instead of prompting from stdin. <parameter>
495 -N</parameter> is implied by <parameter>-c</parameter>.</para>
497 <para>This is particularly useful in scripts and for printing stdin
498 to the server, e.g. <command>-c 'print -'</command>. </para></listitem>
506 <title>OPERATIONS</title>
508 <para>Once the client is running, the user is presented with

513 <para>The backslash ("\\") indicates the current working directory
514 on the server, and will change if the current working directory
517 <para>The prompt indicates that the client is ready and waiting to
518 carry out a user command. Each command is a single word, optionally
519 followed by parameters specific to that command. Command and parameters
520 are space-delimited unless these notes specifically
521 state otherwise. All commands are case-insensitive. Parameters to
522 commands may or may not be case sensitive, depending on the command.
525 <para>You can specify file names which have spaces in them by quoting
526 the name with double quotes, for example "a long file name". </para>
528 <para>Parameters shown in square brackets (e.g., "[parameter]") are
529 optional. If not given, the command will use suitable defaults. Parameters
530 shown in angle brackets (e.g., "<parameter>") are required.
534 <para>Note that all commands operating on the server are actually
535 performed by issuing a request to the server. Thus the behavior may
536 vary from server to server, depending on how the server was implemented.
539 <para>The commands available are given here in alphabetical order. </para>
543 <term>? [command]</term>
544 <listitem><para>If <replaceable>command</replaceable> is specified, the ? command will display
545 a brief informative message about the specified command. If no
546 command is specified, a list of available commands will
547 be displayed. </para></listitem>
551 <term>! [shell command]</term>
552 <listitem><para>If <replaceable>shell command</replaceable> is specified, the !
553 command will execute a shell locally and run the specified shell
554 command. If no command is specified, a local shell will be run.
559 <term>allinfo file</term>
560 <listitem><para>The client will request that the server return
561 all known information about a file or directory (including streams).
566 <term>altname file</term>
567 <listitem><para>The client will request that the server return
568 the "alternate" name (the 8.3 name) for a file or directory.
573 <term>archive <number></term>
574 <listitem><para>Sets the archive level when operating on files.
575 0 means ignore the archive bit, 1 means only operate on files with this bit set,
576 2 means only operate on files with this bit set and reset it after operation,
577 3 means operate on all files and reset it after operation. The default is 0.
583 <listitem><para>Toggle the state of the "backup intent" flag
584 sent to the server on directory listings and file opens. If
585 the "backup intent" flag is true, the server will try and
586 bypass some file system checks if the user has been granted
587 SE_BACKUP or SE_RESTORE privileges. This state is useful when
588 performing a backup or restore operation.
593 <term>blocksize <number></term>
594 <listitem><para>Sets the blocksize parameter for a tar operation. The default is 20.
595 Causes tar file to be written out in blocksize*TBLOCK (normally 512 byte) units.

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

1126 <title>NOTES</title>
1128 <para>Some servers are fussy about the case of supplied usernames,
1129 passwords, share names (AKA service names) and machine names.
1130 If you fail to connect try giving all parameters in uppercase.
1133 <para>It is often necessary to use the -n option when connecting
1134 to some types of servers. For example OS/2 LanManager insists
1135 on a valid NetBIOS name being used, so you need to supply a valid
1136 name that would be known to the server.</para>
1138 <para>smbclient supports long file names where the server
1139 supports the LANMAN2 protocol or above. </para>
1143 <title>ENVIRONMENT VARIABLES</title>
1145 <para>The variable <envar>USER</envar> may contain the
1146 username of the person using the client. This information is
1147 used only if the protocol level is high enough to support
1148 session-level passwords.</para>
1151 <para>The variable <envar>PASSWD</envar> may contain
1152 the password of the person using the client. This information is
1153 used only if the protocol level is high enough to support
1154 session-level passwords. </para>
1156 <para>The variable <envar>LIBSMB_PROG</envar> may contain
1157 the path, executed with system(), which the client should connect
1158 to instead of connecting to a server. This functionality is primarily
1159 intended as a development aid, and works best when using a LMHOSTS
1165 <title>INSTALLATION</title>
1167 <para>The location of the client program is a matter for
1168 individual system administrators. The following are thus
1169 suggestions only. </para>
1171 <para>It is recommended that the smbclient software be installed
1172 in the <filename>/usr/local/samba/bin/</filename> or <filename>
1173 /usr/samba/bin/</filename> directory, this directory readable
1174 by all, writeable only by root. The client program itself should
1175 be executable by all. The client should <emphasis>NOT</emphasis> be
1176 setuid or setgid! </para>
1178 <para>The client log files should be put in a directory readable
1179 and writeable only by the user. </para>
1181 <para>To test the client, you will need to know the name of a
1182 running SMB/CIFS server. It is possible to run <citerefentry><refentrytitle>smbd</refentrytitle>
1183 <manvolnum>8</manvolnum></citerefentry> as an ordinary user - running that server as a daemon
1184 on a user-accessible port (typically any port number over 1024)
1185 would provide a suitable test server. </para>
1190 <title>DIAGNOSTICS</title>
1192 <para>Most diagnostics issued by the client are logged in a
1193 specified log file. The log file name is specified at compile time,
1194 but may be overridden on the command line. </para>
1196 <para>The number and nature of diagnostics available depends
1197 on the debug level used by the client. If you have problems,
