78
79 <para><command>smbclient</command> is a client that can
80 'talk' to an SMB/CIFS server. It offers an interface
81 similar to that of the ftp program (see <citerefentry><refentrytitle>ftp</refentrytitle>
82 <manvolnum>1</manvolnum></citerefentry>).
83 Operations include things like getting files from the server
84 to the local machine, putting files from the local machine to
85 the server, retrieving directory information from the server
86 and so on. </para>

96 <listitem><para>servicename is the name of the service
97 you want to use on the server. A service name takes the form
98 <filename>//server/service</filename> where <parameter>server
99 </parameter> is the NetBIOS name of the SMB/CIFS server
100 offering the desired service and <parameter>service</parameter>
101 is the name of the service offered. Thus to connect to
102 the service "printer" on the SMB/CIFS server "smbserver",
103 you would use the servicename <filename>//smbserver/printer
104 </filename></para>
105
106 <para>Note that the server name required is NOT necessarily
107 the IP (DNS) host name of the server ! The name required is
108 a NetBIOS server name, which may or may not be the
109 same as the IP hostname of the machine running the server.
110 </para>
111
112 <para>The server name is looked up according to either
113 the <parameter>-R</parameter> parameter to <command>smbclient</command> or
114 using the name resolve order parameter in
115 the <citerefentry><refentrytitle>smb.conf</refentrytitle>

133 the desired service does not require one. (If no password is
134 required, simply press ENTER to provide a null password.)
135 </para>
136
137 <para>Note: Some servers (including OS/2 and Windows for
138 Workgroups) insist on an uppercase password. Lowercase

147 <term>-R &lt;name resolve order&gt;</term>
148 <listitem><para>This option is used by the programs in the Samba
149 suite to determine what naming services and in what order to resolve
150 host names to IP addresses. The option takes a space-separated
151 string of different name resolution options.</para>
152
153 <para>The options are :"lmhosts", "host", "wins" and "bcast". They
154 cause names to be resolved as follows:</para>
155
156 <itemizedlist>
157 <listitem><para><constant>lmhosts</constant>: Lookup an IP
158 address in the Samba lmhosts file. If the line in lmhosts has
159 no name type attached to the NetBIOS name (see
160 the <citerefentry><refentrytitle>lmhosts</refentrytitle>
161 <manvolnum>5</manvolnum></citerefentry> for details) then
162 any name type matches for lookup.</para>
163 </listitem>
164
165 <listitem><para><constant>host</constant>: Do a standard host
166 name to IP address resolution, using the system <filename>/etc/hosts
167 </filename>, NIS, or DNS lookups. This method of name resolution
168 is operating system dependent, for instance on IRIX or Solaris this
169 may be controlled by the <filename>/etc/nsswitch.conf</filename>
170 file). Note that this method is only used if the NetBIOS name
171 type being queried is the 0x20 (server) name type, otherwise
172 it is ignored.</para>
173 </listitem>
174
175 <listitem><para><constant>wins</constant>: Query a name with
176 the IP address listed in the <parameter>wins server</parameter>
177 parameter. If no WINS server has
178 been specified this method will be ignored.</para>
179 </listitem>
180
181 <listitem><para><constant>bcast</constant>: Do a broadcast on
182 each of the known local interfaces listed in the
183 <parameter>interfaces</parameter>
184 parameter. This is the least reliable of the name resolution
185 methods as it depends on the target host being on a locally
186 connected subnet.</para>
187 </listitem>
188 </itemizedlist>
189
190 <para>If this parameter is not set then the name resolve order
191 defined in the <citerefentry><refentrytitle>smb.conf</refentrytitle>
192 <manvolnum>5</manvolnum></citerefentry> file parameter
193 (name resolve order) will be used. </para>
194
195 <para>The default order is lmhosts, host, wins, bcast and without

206 the "WinPopup" protocol, to another computer. Once a connection is
207 established you then type your message, pressing ^D (control-D) to
208 end. </para>
209
210 <para>If the receiving computer is running WinPopup the user will
211 receive the message and probably a beep. If they are not running
212 WinPopup the message will be lost, and no error message will
213 occur. </para>
214
215 <para>The message is also automatically truncated if the message
216 is over 1600 bytes, as this is the limit of the protocol.
217 </para>
218
219 <para>
220 One useful trick is to pipe the message through <command>smbclient</command>.
221 For example: smbclient -M FRED &lt; mymessage.txt will send the
222 message in the file <filename>mymessage.txt</filename> to the
223 machine FRED.
224 </para>
225
226 <para>You may also find the <parameter>-U</parameter> and
227 <parameter>-I</parameter> options useful, as they allow you to
228 control the FROM and TO parts of the message. </para>

230 <para>See the <parameter>message command</parameter> parameter in the <citerefentry><refentrytitle>smb.conf</refentrytitle>

350
351 <itemizedlist>
352 <listitem><para><parameter>c</parameter> - Create a tar file on UNIX.
353 Must be followed by the name of a tar file, tape device
354 or "-" for standard output. If using standard output you must
355 turn the log level to its lowest value -d0 to avoid corrupting
356 your tar file. This flag is mutually exclusive with the
357 <parameter>x</parameter> flag. </para></listitem>
358
359 <listitem><para><parameter>x</parameter> - Extract (restore) a local
360 tar file back to a share. Unless the -D option is given, the tar
361 files will be restored from the top level of the share. Must be
362 followed by the name of the tar file, device or "-" for standard
363 input. Mutually exclusive with the <parameter>c</parameter> flag.
364 Restored files have their creation times (mtime) set to the
365 date saved in the tar file. Directories currently do not get
366 their creation dates restored properly. </para></listitem>
367
368 <listitem><para><parameter>I</parameter> - Include files and directories.
369 Is the default behavior when filenames are specified above. Causes
370 files to be included in an extract or create (and therefore
371 everything else to be excluded). See example below. Filename globbing
372 works in one of two ways. See <parameter>r</parameter> below. </para></listitem>
373
374 <listitem><para><parameter>X</parameter> - Exclude files and directories.
375 Causes files to be excluded from an extract or create. See

377 See <parameter>r</parameter> below. </para></listitem>
378
379 <listitem><para><parameter>F</parameter> - File containing a list of files and directories.
380 The <parameter>F</parameter> causes the name following the tarfile to
381 create to be read as a filename that contains a list of files and directories to
382 be included in an extract or create (and therefore everything else to be excluded).
383 See example below. Filename globbing works in one of two ways.
384 See <parameter>r</parameter> below.
385 </para></listitem>
386
387 <listitem><para><parameter>b</parameter> - Blocksize. Must be followed
388 by a valid (greater than zero) blocksize. Causes tar file to be
389 written out in blocksize*TBLOCK (usually 512 byte) blocks.
390 </para></listitem>
391
392 <listitem><para><parameter>g</parameter> - Incremental. Only back up
393 files that have the archive bit set. Useful only with the
394 <parameter>c</parameter> flag. </para></listitem>
395
396 <listitem><para><parameter>q</parameter> - Quiet. Keeps tar from printing
397 diagnostics as it works. This is the same as tarmode quiet.
398 </para></listitem>
399
400 <listitem><para><parameter>r</parameter> - Regular expression include
401 or exclude. Uses regular expression matching for
402 excluding or excluding files if compiled with HAVE_REGEX_H.
403 However this mode can be very slow. If not compiled with
404 HAVE_REGEX_H, does a limited wildcard match on '*' and '?'.
405 </para></listitem>
406
407 <listitem><para><parameter>N</parameter> - Newer than. Must be followed
408 by the name of a file whose date is compared against files found
409 on the share during a create. Only files newer than the file
410 specified are backed up to the tar file. Useful only with the
411 <parameter>c</parameter> flag. </para></listitem>
412
413 <listitem><para><parameter>a</parameter> - Set archive bit. Causes the
414 archive bit to be reset when a file is backed up. Useful with the

419 <para><emphasis>Tar Long File Names</emphasis></para>
420
421 <para><command>smbclient</command>'s tar option now supports long
422 file names both on backup and restore. However, the full path
423 name of the file must be less than 1024 bytes. Also, when

1052
1053 <para>Some servers are fussy about the case of supplied usernames,
1054 passwords, share names (AKA service names) and machine names.
1055 If you fail to connect try giving all parameters in uppercase.
1056 </para>
1057
1058 <para>It is often necessary to use the -n option when connecting
1059 to some types of servers. For example OS/2 LanManager insists
1060 on a valid NetBIOS name being used, so you need to supply a valid
1061 name that would be known to the server.</para>
1062
1063 <para>smbclient supports long file names where the server
1064 supports the LANMAN2 protocol or above. </para>

1068 <title>ENVIRONMENT VARIABLES</title>
1069
1070 <para>The variable <envar>USER</envar> may contain the
1071 username of the person using the client. This information is
1072 used only if the protocol level is high enough to support
1073 session-level passwords.</para>
1074
1075
1076 <para>The variable <envar>PASSWD</envar> may contain
1077 the password of the person using the client. This information is
1078 used only if the protocol level is high enough to support
1079 session-level passwords. </para>
1080
1081 <para>The variable <envar>LIBSMB_PROG</envar> may contain
1082 the path, executed with system(), which the client should connect
1083 to instead of connecting to a server. This functionality is primarily
1084 intended as a development aid, and works best when using a LMHOSTS
1085 file</para>

1090 <title>INSTALLATION</title>
1091
1092 <para>The location of the client program is a matter for
1093 individual system administrators. The following are thus
1094 suggestions only. </para>
1095
1096 <para>It is recommended that the smbclient software be installed
1097 in the <filename>/usr/local/samba/bin/</filename> or <filename>
1098 /usr/samba/bin/</filename> directory, this directory readable
1099 by all, writeable only by root. The client program itself should
1100 be executable by all. The client should <emphasis>NOT</emphasis> be
1101 setuid or setgid! </para>
1102
1103 <para>The client log files should be put in a directory readable
1104 and writeable only by the user. </para>
1105
1106 <para>To test the client, you will need to know the name of a
1107 running SMB/CIFS server. It is possible to run <citerefentry><refentrytitle>smbd</refentrytitle>
1108 <manvolnum>8</manvolnum></citerefentry> as an ordinary user - running that server as a daemon
1109 on a user-accessible port (typically any port number over 1024)
1110 would provide a suitable test server. </para>

1115 <title>DIAGNOSTICS</title>
1116
1117 <para>Most diagnostics issued by the client are logged in a
1118 specified log file. The log file name is specified at compile time,
1119 but may be overridden on the command line. </para>
1120
1121 <para>The number and nature of diagnostics available depends
1122 on the debug level used by the client. If you have problems,
1123 set the debug level to 3 and peruse the log files. </para>

1136
1137 <para>The original Samba software and related utilities
1138 were created by Andrew Tridgell. Samba is now developed
1139 by the Samba Team as an Open Source project similar
1140 to the way the Linux kernel is developed.</para>
1141
1142 <para>The original Samba man pages were written by Karl Auer.
1143 The man page sources were converted to YODL format (another
1144 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
1145 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
1146 release by Jeremy Allison. The conversion to DocBook for
1147 Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0
1148 was done by Alexander Bokovoy.</para>
