        <title>SYNOPSIS</title>

        <para>The <filename>smb.conf</filename> file is a configuration 
        file for the Samba suite. <filename>smb.conf</filename> contains 
        runtime configuration information for the Samba programs. The
        <filename>smb.conf</filename> file is designed to be configured and 
        administered by the <ulink url="swat.8.html"><command>swat(8)</command>
        </ulink> program. The complete description of the file format and 
        possible parameters held within are here for reference purposes.</para>
</refsect1>

<refsect1>
        <title id="FILEFORMATSECT">FILE FORMAT</title>

        <para>The file consists of sections and parameters. A section 
        begins with the name of the section in square brackets and continues 
        until the next section begins. Sections contain parameters of the 
        form</para>

        <para><replaceable>name</replaceable> = <replaceable>value
        </replaceable></para>

        <para>The file is line-based - that is, each newline-terminated 
        line represents either a comment, a section name or a parameter.</para>

        <para>Section and parameter names are not case sensitive.</para>

        <para>Only the first equals sign in a parameter is significant. 
        Whitespace before or after the first equals sign is discarded. 
        Leading, trailing and internal whitespace in section and parameter 
        names is irrelevant. Leading and trailing whitespace in a parameter 
        value is discarded. Internal whitespace within a parameter value 
        is retained verbatim.</para>

        <para>Any line beginning with a semicolon (';') or a hash ('#') 
        character is ignored, as are lines containing only whitespace.</para>

        <para>Any line ending in a '\' is continued
        on the next line in the customary UNIX fashion.</para>

        <para>The values following the equals sign in parameters are all 
        either a string (no quotes needed) or a boolean, which may be given 
        as yes/no, 0/1 or true/false. Case is not significant in boolean 
        values, but is preserved in string values. Some items such as 
        create modes are numeric.</para>

        <title>SECTION DESCRIPTIONS</title>

        <para>Each section in the configuration file (except for the
        [global] section) describes a shared resource (known
        as a "share"). The section name is the name of the 
        shared resource and the parameters within the section define 
        the shares attributes.</para>

        <para>There are three special sections, [global],
        [homes] and [printers], which are
        described under <emphasis>special sections</emphasis>. The
        following notes apply to ordinary section descriptions.</para>

        <para>A share consists of a directory to which access is being 
        given plus a description of the access rights which are granted 
        to the user of the service. Some housekeeping options are 
        also specifiable.</para>
        
        <para>Sections are either file share services (used by the 
        client as an extension of their native file systems) or 
        printable services (used by the client to access print services 
        on the host running the server).</para>
        
        <para>Sections may be designated <emphasis>guest</emphasis> services, 
        in which case no password is required to access them. A specified 
        UNIX <emphasis>guest account</emphasis> is used to define access
        privileges in this case.</para>

        <para>Sections other than guest services will require a password 
        to access them. The client provides the username. As older clients 
        only provide passwords and not usernames, you may specify a list 
        of usernames to check against the password using the "user=" 
        option in the share definition. For modern clients such as 
        Windows 95/98/ME/NT/2000, this should not be necessary.</para>

        <para>Note that the access rights granted by the server are 
        masked by the access rights granted to the specified or guest 
        UNIX user by the host system. The server does not grant more
        access than the host system grants.</para>
        
        <para>The following sample section defines a file space share. 
        The user has write access to the path <filename>/home/bar</filename>. 
        The share is accessed via the share name "foo":</para>

        <screen>
        <computeroutput>
        [foo]
                path = /home/bar
                writeable = true
        </computeroutput>
        </screen>

        <para>The following sample section defines a printable share. 
        The share is readonly, but printable. That is, the only write 
        access permitted is via calls to open, write to and close a 
        spool file. The <emphasis>guest ok</emphasis> parameter means 
        access will be permitted as the default guest user (specified 
        elsewhere):</para>

        <screen>
        <computeroutput>
        [aprinter]
                path = /usr/spool/public
                writeable = false
                printable = true
                guest ok = true
        </computeroutput>
        </screen>
</refsect1>

        <title>SPECIAL SECTIONS</title>
        
        <refsect2>
                <title>The [global] section</title>
                
                <para>parameters in this section apply to the server 
                as a whole, or are defaults for sections which do not 
                specifically define certain items. See the notes 
                under PARAMETERS for more information.</para>
        </refsect2>
        
        <refsect2>
                <title id="HOMESECT">The [homes] section</title>
                
                <para>If a section called homes is included in the 
                configuration file, services connecting clients to their 
                home directories can be created on the fly by the server.</para>

                <para>When the connection request is made, the existing 
                sections are scanned. If a match is found, it is used. If no 
                match is found, the requested section name is treated as a 
                user name and looked up in the local password file. If the 
                name exists and the correct password has been given, a share is 
                created by cloning the [homes] section.</para>
                
                <para>Some modifications are then made to the newly 
                created share:</para>
                
                <itemizedlist>
                <listitem><para>The share name is changed from homes to 
                the located username.</para></listitem>

                <listitem><para>If no path was given, the path is set to
                the user's home directory.</para></listitem>
                </itemizedlist>

                <para>If you decide to use a <emphasis>path=</emphasis> line 
                in your [homes] section then you may find it useful 
                to use the %S macro. For example :</para>

                <para><userinput>path=/data/pchome/%S</userinput></para>

                <para>would be useful if you have different home directories 
                for your PCs than for UNIX access.</para>

                <para>This is a fast and simple way to give a large number 
                of clients access to their home directories with a minimum 
                of fuss.</para>

                <para>A similar process occurs if the requested section 
                name is "homes", except that the share name is not 
                changed to that of the requesting user. This method of using 
                the [homes] section works well if different users share 
                a client PC.</para>
                
                <para>The [homes] section can specify all the parameters 
                a normal service section can specify, though some make more sense 
                than others. The following is a typical and suitable [homes]
                section:</para>

                <screen>
                <computeroutput>
                [homes]
                        writeable = yes
                </computeroutput>
                </screen>
        
                <para>An important point is that if guest access is specified 
                in the [homes] section, all home directories will be 
                visible to all clients <emphasis>without a password</emphasis>. 
                In the very unlikely event that this is actually desirable, it 
                would be wise to also specify <emphasis>read only
                access</emphasis>.</para>

                <para>Note that the <emphasis>browseable</emphasis> flag for 
                auto home directories will be inherited from the global browseable 
                flag, not the [homes] browseable flag. This is useful as 
                it means setting browseable=no in the [homes] section 
                will hide the [homes] share but make any auto home 
                directories visible.</para>
        </refsect2>
        
        <refsect2>
                <title id="PRINTERSSECT">The [printers] section</title>
                
                <para>This section works like [homes], 
                but for printers.</para>

                <para>If a [printers] section occurs in the 
                configuration file, users are able to connect to any printer 
                specified in the local host's printcap file.</para>

                <para>When a connection request is made, the existing sections 
                are scanned. If a match is found, it is used. If no match is found, 
                but a [homes] section exists, it is used as described
                above. Otherwise, the requested section name is treated as a 
                printer name and the appropriate printcap file is scanned to see 
                if the requested section name is a valid printer share name. If 
                a match is found, a new printer share is created by cloning 
                the [printers] section.</para>

                <para>A few modifications are then made to the newly created 
                share:</para>

                <itemizedlist>
                <listitem><para>The share name is set to the located printer 
                name</para></listitem>

                <listitem><para>If no printer name was given, the printer name 
                is set to the located printer name</para></listitem>

                <listitem><para>If the share does not permit guest access and 
                no username was given, the username is set to the located 
                printer name.</para></listitem>
                </itemizedlist>

                <para>Note that the [printers] service MUST be 
                printable - if you specify otherwise, the server will refuse 
                to load the configuration file.</para>
                
                <para>Typically the path specified would be that of a 
                world-writeable spool directory with the sticky bit set on 
                it. A typical [printers] entry would look like 
                this:</para>

                <screen><computeroutput>
                [printers]
                        path = /usr/spool/public
                        guest ok = yes
                        printable = yes 
                </computeroutput></screen>

                <para>All aliases given for a printer in the printcap file 
                are legitimate printer names as far as the server is concerned. 
                If your printing subsystem doesn't work like that, you will have 
                to set up a pseudo-printcap. This is a file consisting of one or 
                more lines like this:</para>

                <screen>
                <computeroutput>
                alias|alias|alias|alias...    
                </computeroutput>
                </screen>

                <para>Each alias should be an acceptable printer name for 
                your printing subsystem. In the [global] section, specify 
                the new file as your printcap.  The server will then only recognize 
                names found in your pseudo-printcap, which of course can contain 
                whatever aliases you like. The same technique could be used 
                simply to limit access to a subset of your local printers.</para>

                <para>An alias, by the way, is defined as any component of the 
                first entry of a printcap record. Records are separated by newlines,
                components (if there are more than one) are separated by vertical 
                bar symbols ('|').</para>
                
                <para>NOTE: On SYSV systems which use lpstat to determine what 
                printers are defined on the system you may be able to use
                "printcap name = lpstat" to automatically obtain a list 
                of printers. See the "printcap name" option 
                for more details.</para>
        </refsect2>
</refsect1>

<refsect1>
        <title>PARAMETERS</title>

        <para>parameters define the specific attributes of sections.</para>

        <para>Some parameters are specific to the [global] section
        (e.g., <emphasis>security</emphasis>).  Some parameters are usable 
        in all sections (e.g., <emphasis>create mode</emphasis>). All others 
        are permissible only in normal sections. For the purposes of the 
        following descriptions the [homes] and [printers]
        sections will be considered normal.  The letter <emphasis>G</emphasis> 
        in parentheses indicates that a parameter is specific to the
        [global] section. The letter <emphasis>S</emphasis>
        indicates that a parameter can be specified in a service specific
        section. Note that all <emphasis>S</emphasis> parameters can also be specified in 
        the [global] section - in which case they will define
        the default behavior for all services.</para>

        <para>parameters are arranged here in alphabetical order - this may 
        not create best bedfellows, but at least you can find them! Where 
        there are synonyms, the preferred synonym is described, others refer 
        to the preferred synonym.</para>
</refsect1>

<refsect1>
        <title>VARIABLE SUBSTITUTIONS</title>

        <para>Many of the strings that are settable in the config file 
        can take substitutions. For example the option "path =
        /tmp/%u" would be interpreted as "path = 
        /tmp/john" if the user connected with the username john.</para>

        <para>These substitutions are mostly noted in the descriptions below, 
        but there are some general substitutions which apply whenever they 
        might be relevant. These are:</para>

                <para>Normally, a Samba server requires that UNIX users are 
                created for all users accessing files on this server. For sites 
                that use Windows NT account databases as their primary user database 
                creating these users and keeping the user list in sync with the 
                Windows NT PDC is an onerous task. This option allows <ulink 
                url="smbd.8.html">smbd</ulink> to create the required UNIX users 
                <emphasis>ON DEMAND</emphasis> when a user accesses the Samba server.</para>

                <para>In order to use this option, <ulink url="smbd.8.html">smbd</ulink> 
                must be set to <parameter>security=server</parameter> or <parameter>

                must be set to a full pathname for a script that will create a UNIX 
                user given one argument of <parameter>%u</parameter>, which expands into 
                the UNIX user name to create.</para>

                <para>When the Windows user attempts to access the Samba server, 
                at login (session setup in the SMB protocol) time, <ulink url="smbd.8.html">
                smbd</ulink> contacts the <parameter>password server</parameter> and 
                attempts to authenticate the given user with the given password. If the 
                authentication succeeds then <command>smbd</command> 
                attempts to find a UNIX user in the UNIX password database to map the 
                Windows user into. If this lookup fails, and <parameter>add user script
                </parameter> is set then <command>smbd</command> will
                call the specified script <emphasis>AS ROOT</emphasis>, expanding 
                any <parameter>%u</parameter> argument to be the user name to create.</para>

                <para>If this script successfully creates the user then <command>smbd
                </command> will continue on as though the UNIX user
                already existed. In this way, UNIX users are dynamically created to
                match existing Windows NT accounts.</para>

                <para>Normally, a Samba server requires that UNIX users are 
                created for all users accessing files on this server. For sites 
                that use Windows NT account databases as their primary user database 
                creating these users and keeping the user list in sync with the 
                Windows NT PDC is an onerous task. This option allows <command>
                smbd</command> to delete the required UNIX users <emphasis>ON 
                DEMAND</emphasis> when a user accesses the Samba server and the 
                Windows NT user no longer exists.</para>
                
                <para>In order to use this option, <command>smbd</command> must be 
                set to <parameter>security=domain</parameter> and <parameter>delete 
                user script</parameter> must be set to a full pathname for a script 
                that will delete a UNIX user given one argument of <parameter>%u
                </parameter>, which expands into the UNIX user name to delete.
                <emphasis>NOTE</emphasis> that this is different to the <link
                linkend="ADDUSERSCRIPT"><parameter>add user script</parameter></link>
                which will work with the <parameter>security=server</parameter> option 
                as well as <parameter>security=domain</parameter>. The reason for this
                is only when Samba is a domain member does it get the information
                on an attempted user logon that a user no longer exists. In the
                <parameter>security=server</parameter> mode a missing user
                is treated the same as an invalid password logon attempt. Deleting
                the user in this circumstance would not be a good idea.</para>

                <para>When the Windows user attempts to access the Samba server, 
                at <emphasis>login</emphasis> (session setup in the SMB protocol) 
                time, <command>smbd</command> contacts the <link linkend="PASSWORDSERVER">
                <parameter>password server</parameter></link> and attempts to authenticate 
                the given user with the given password. If the authentication fails 
                with the specific Domain error code meaning that the user no longer 
                exists then <command>smbd</command> attempts to find a UNIX user in 
                the UNIX password database that matches the Windows user account. If 
                this lookup succeeds, and <parameter>delete user script</parameter> is 
                set then <command>smbd</command> will all the specified script 
                <emphasis>AS ROOT</emphasis>, expanding any <parameter>%u</parameter> 
                argument to be the user name to delete.</para>

                <para>This script should delete the given UNIX username. In this way, 
                UNIX users are dynamically deleted to match existing Windows NT

                <listitem><para>NTFS and Windows VFAT file systems keep a create 
                time for all files and directories. This is not the same as the 
                ctime - status change time - that Unix keeps, so Samba by default 
                reports the earliest of the various times Unix does keep. Setting 
                this parameter for a share causes Samba to always report midnight 
                1-1-1980 as the create time for directories.</para>

                <para>This option is mainly used as a compatibility option for 
                Visual C++ when used against Samba shares. Visual C++ generated 
                makefiles have the object directory as a dependency for each object 
                file, and a make rule to create the directory. Also, when NMAKE 
                compares timestamps it uses the creation time when examining a 
                directory. Thus the object directory will be created if it does not 
                exist, but once it does exist it will always have an earlier 
                timestamp than the object files it contains.</para>

                <para>However, Unix time semantics mean that the create time 
                reported by Samba will be updated whenever a file is created or 
                or deleted in the directory.  NMAKE finds all object files in 
                the object directory.  The timestamp of the last one built is then 
                compared to the timestamp of the object dircetory.  If the 
                directory's timestamp if newer, then all object files
                will be rebuilt.  Enabling this option 
                ensures directories always predate their contents and an NMAKE build 
                will proceed as expected.</para>

                The netmasks of the latter two interfaces would be set to 255.255.255.0.</para>

                they may not cache writes or lock requests) and increases performance

                <para>An example is:</para>

                <para><command>message command = csh -c 'xedit %s;rm %s' &</command>

                <para>Here's a way of sending the messages as mail to root:</para>

                <para><command>message command = /bin/mail -s 'message from %f on

                <para>If you don't have a message command then the message 
                won't be delivered and Samba will tell the sender there was 
                an error. Unfortunately WfWg totally ignores the error code 
                and carries on regardless, saying that the message was delivered.

                If the amount of data being transferred in several of the SMB 
                commands (currently SMBwrite, SMBwriteX and SMBreadbraw) is larger

                <para>This overlapping works best when the speeds of disk and

                but it doesn't.  Setting it to true will force these anonymous 
                connections to be denied, and the client will be required to always 
                supply a username and password when connecting. Use of this parameter

                <para>This parameter makes the use of macro expansions that rely

                the machine's account in  the domain doesn't exist or the password is 
                bad.  The best way to deal  with this is to reboot NT client machines

                <para>This is the default security setting in Samba 2.2. 
                With user-level security a client must first "log=on" with a

                linkend="USERNAMEMAP"><parameter>username map</parameter></link> 
                parameter). Encrypted passwords (see the <link linkend="ENCRYPTPASSWORDS">
                <parameter>encrypted passwords</parameter></link> parameter) can also
                be used in this security mode. Parameters such as <link linkend="USER">
                <parameter>user</parameter></link> and <link linkend="GUESTONLY">
                <parameter>guest only</parameter></link> if set are then applied and

                <listitem><para>Many Windows applications (including the Windows 
                98 explorer shell) seem to confuse flushing buffer contents to 
                disk with doing a sync to disk. Under UNIX, a sync call forces 
                the process to be suspended until the kernel has ensured that 
                all outstanding data in kernel disk buffers has been safely stored 
                onto stable storage. This is very slow and should only be done 
                rarely. Setting this parameter to <constant>no</constant> (the 
                default) means that smbd ignores the Windows applications requests for
                a sync call. There is only a possibility of losing data if the
                operating system itself that Samba is running on crashes, so there is
                little danger in this default setting. In addition, this fixes many

                <para>The <parameter>username</parameter> line is needed only when 
                the PC is unable to supply its own username. This is the case 
                for the COREPLUS protocol or where your users have different WfWg 
                usernames to UNIX usernames. In both these cases you may also be 
                better using the \\server\share%user syntax instead.</para>

                <para>The <parameter>username</parameter> line is not a great 
                solution in many cases as it means Samba will try to validate 
                the supplied password against each of the usernames in the 
                <parameter>username</parameter> line in turn. This is slow and 
                a bad idea for lots of users in case of duplicate passwords. 
                You may get timeouts or security breaches using this parameter 
                unwisely.</para>

                <para>Samba relies on the underlying UNIX security. This 
                parameter does not restrict who can login, it just offers hints 
                to the Samba server as to what usernames might correspond to the 
                supplied password. Users can login as whoever they please and 
                they will be able to do no more damage than if they started a 
                telnet session. The daemon runs as the user that they log in as, 
                so they cannot do anything that user cannot do.</para>

                <para>To restrict a service to a particular set of users you 
                can use the <link linkend="VALIDUSERS"><parameter>valid users

                <para>If any of the usernames begin with a '@' then the name 
                will be looked up first in the yp netgroups list (if Samba 
                is compiled with netgroup support), followed by a lookup in 
                the UNIX groups database and will expand to a list of all users 
                in the group of that name.</para>
                
                <para>If any of the usernames begin with a '+' then the name 
                will be looked up only in the UNIX groups database and will 
                expand to a list of all users in the group of that name.</para>

                <para>If any of the usernames begin with a '&'then the name

                <listitem><para>This option helps Samba to try and 'guess' at 
                the real UNIX username, as many DOS clients send an all-uppercase 
                username. By default Samba tries all lowercase, followed by the 
                username with the first letter capitalized, and fails if the 
                username is not found on the UNIX machine.</para>

                <para>If this parameter is set to non-zero the behavior changes. 
                This parameter is a number that specifies the number of uppercase

                higher the number the more combinations will be tried, but the slower
                the discovery of usernames will be. Use this parameter when you have
                strange usernames on your UNIX machine, such as <constant>AstrangeUser
                </constant>.</para>

                <term><anchor id="USERNAMEMAP">username map (G)</term>
                <listitem><para>This option allows you to specify a file containing 
                a mapping of usernames from the clients to the server. This can be 
                used for several purposes. The most common is to map usernames 
                that users use on DOS or Windows machines to those that the UNIX 
                box uses. The other is to map multiple users to a single username 
                so that they can more easily share files.</para>

                <para>The map file is parsed line by line. Each line should 
                contain a single UNIX username on the left then a '=' followed 
                by a list of usernames on the right. The list of usernames on the 
                right may contain names of the form @group in which case they 
                will match any UNIX username in that group. The special client 
                name '*' is a wildcard and matches any name. Each line of the 
                map file may be up to 1023 characters long.</para>

                <para>The file is processed on each line by taking the 
                supplied username and comparing it with each username on the right 
                hand side of the '=' signs. If the supplied name matches any of 
                the names on the right hand side then it is replaced with the name 
                on the left. Processing then continues with the next line.</para>

                <para>If any line begins with a '#' or a ';' then it is 
                ignored</para>

                <para>If any line begins with an '!' then the processing 
                will stop after that line if a mapping was done by the line. 
                Otherwise mapping continues with every line being processed. 
                Using '!' is most useful when you have a wildcard mapping line 
                later in the file.</para>
                
                <para>For example to map from the name <constant>admin</constant> 
                or <constant>administrator</constant> to the UNIX name <constant>
                root</constant> you would use:</para>

                <para><command>root = admin administrator</command></para>

                <para>Or to map anyone in the UNIX group <constant>system</constant> 
                to the UNIX name <constant>sys</constant> you would use:</para>

                <para><command>sys = @system</command></para>

                <para>You can have as many mappings as you like in a username 
                map file.</para>
                
                
                <para>If your system supports the NIS NETGROUP option then 
                the netgroup database is checked before the <filename>/etc/group
                </filename> database for matching groups.</para>

                <para>You can map Windows usernames that have spaces in them
                 by using double quotes around the name. For example:</para>

                <para><command>tridge = "Andrew Tridgell"</command></para>

                <para>would map the windows username "Andrew Tridgell" to the 
                unix username "tridge".</para>

                <para>The following example would map mary and fred to the 
                unix user sys, and map the rest to guest. Note the use of the 
                '!' to tell Samba to stop processing if it gets a match on 
                that line.</para>

                <para><programlisting>
                !sys = mary fred
                guest = *
                </programlisting></para>

                <para>Note that the remapping is applied to all occurrences 
                of usernames. Thus if you connect to \\server\fred and <constant>
                fred</constant> is remapped to <constant>mary</constant> then you 
                will actually be connecting to \\server\mary and will need to 
                supply a password suitable for <constant>mary</constant> not 
                <constant>fred</constant>. The only exception to this is the 
                username passed to the <link linkend="PASSWORDSERVER"><parameter>
                password server</parameter></link> (if you have one). The password 
                server will receive whatever username the client supplies without 
                modification.</para>

                <para>Also note that no reverse mapping is done. The main effect 
                this has is with printing. Users who have been mapped may have 
                trouble deleting print jobs as PrintManager under WfWg will think 
                they don't own the print job.</para>

        <para>Although the configuration file permits service names 
        to contain spaces, your client software may not. Spaces will 
        be ignored in comparisons anyway, so it shouldn't be a 
        problem - but be aware of the possibility.</para>

        <para>On a similar note, many clients - especially DOS clients - 
        limit service names to eight characters. <ulink url="smbd.8.html">smbd(8)
        </ulink> has no such limitation, but attempts to connect from such 
        clients will fail if they truncate the service names.  For this reason 
        you should probably keep your service names down to eight characters 
        in length.</para>

        <para>Use of the [homes] and [printers] special sections make life 
        for an administrator easy, but the various combinations of default 
        attributes can be tricky. Take extreme care when designing these 
        sections. In particular, ensure that the permissions on spool 
        directories are correct.</para>

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