The <strong>smb.conf</strong> file is designed to be +configured and administered by the <a href="swat.8.html"><strong>swat (8)</strong></a> +program. The complete description of the file format and possible +parameters held within are here for reference purposes. +<p><br><a name="FILEFORMAT"></a> +<h2>FILE FORMAT</h2> + +<p><br>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 +<p><br><code>'name = value'</code> +<p><br>The file is line-based - that is, each newline-terminated line +represents either a comment, a section name or a parameter. +<p><br>Section and parameter names are not case sensitive. +<p><br>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. +<p><br>Any line beginning with a semicolon (';') or a hash ('#') character is +ignored, as are lines containing only whitespace. +<p><br>Any line ending in a <code>'\'</code> is "continued" on the next line in the +customary UNIX fashion. +<p><br>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. +<p><br><a name="SECTIONDESCRIPTIONS"></a> +<h2>SECTION DESCRIPTIONS</h2> + +<p><br>Each section in the configuration file (except for the +<a href="smb.conf.5.html#global"><strong>[global]</strong></a> section) describes a shared resource (known +as a <em>"share"</em>). The section name is the name of the shared resource +and the parameters within the section define the shares attributes. +<p><br>There are three special sections, <a href="smb.conf.5.html#global"><strong>[global]</strong></a>, +<a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> and <a href="smb.conf.5.html#printers"><strong>[printers]</strong></a>, which are +described under <a href="smb.conf.5.html#SPECIALSECTIONS"><strong>'special sections'</strong></a>. The +following notes apply to ordinary section descriptions. +<p><br>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. +<p><br>Sections are either filespace 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). +<p><br>Sections may be designated <a href="smb.conf.5.html#guestok"><strong>guest</strong></a> services, in which +case no password is required to access them. A specified UNIX +<a href="smb.conf.5.html#guestaccount"><strong>guest account</strong></a> is used to define access +privileges in this case. +<p><br>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 <a href="smb.conf.5.html#user"><strong>"user="</strong></a> option in +the share definition. For modern clients such as Windows 95/98 and +Windows NT, this should not be neccessary. +<p><br>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. +<p><br>The following sample section defines a file space share. The user has +write access to the path <code>/home/bar</code>. The share is accessed via +the share name "foo": +<p><br><pre> + + + [foo] + path = /home/bar + writable = true + + +</pre> + +<p><br>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 +<a href="smb.conf.5.html#guestok"><strong>'guest ok'</strong></a> parameter means access will be permitted +as the default guest user (specified elsewhere): +<p><br><pre> + + [aprinter] + path = /usr/spool/public + read only = true + printable = true + guest ok = true + +</pre> + +<p><br><a name="SPECIALSECTIONS"></a> +<h2>SPECIAL SECTIONS</h2> + +<p><br><ul> +<p><br><a name="global"></a> +<li><strong><strong>The [global] section</strong></strong> +<p><br>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 <a href="smb.conf.5.html#PARAMETERS"><strong>'PARAMETERS'</strong></a> for more +information. +<p><br><a name="homes"></a> +<li><strong><strong>The [homes] section</strong></strong> +<p><br>If a section called <code>'homes'</code> is included in the configuration file, +services connecting clients to their home directories can be created +on the fly by the server. +<p><br>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. +<p><br>Some modifications are then made to the newly created share: +<p><br><ul> +<p><br><li > The share name is changed from <code>'homes'</code> to the located +username +<p><br><li > If no path was given, the path is set to the user's home +directory. +<p><br></ul> +<p><br>If you decide to use a <a href="smb.conf.5.html#path"><strong>path=</strong></a> line in your [homes] +section then you may find it useful to use the <a href="smb.conf.5.html#percentS"><strong>%S</strong></a> +macro. For example : +<p><br><code>path=/data/pchome/%S</code> +<p><br>would be useful if you have different home directories for your PCs +than for UNIX access. +<p><br>This is a fast and simple way to give a large number of clients access +to their home directories with a minimum of fuss. +<p><br>A similar process occurs if the requested section name is <code>"homes"</code>, +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. +<p><br>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: +<p><br><pre> + + [homes] + writable = yes + +</pre> + +<p><br>An important point is that if guest access is specified in the [homes] +section, all home directories will be visible to all clients +<strong>without a password</strong>. In the very unlikely event that this is +actually desirable, it would be wise to also specify <a href="smb.conf.5.html#readonly"><strong>read only +access</strong></a>. +<p><br>Note that the <a href="smb.conf.5.html#browseable"><strong>browseable</strong></a> 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. +<p><br><a name="printers"></a> +<li><strong><strong>The [printers] section</strong></strong> +<p><br>This section works like <a href="smb.conf.5.html#homes"><strong>[homes]</strong></a>, but for printers. +<p><br>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. +<p><br>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 +<a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> 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. +<p><br>A few modifications are then made to the newly created share: +<p><br><ul> +<p><br><li > The share name is set to the located printer name +<p><br><li > If no printer name was given, the printer name is set to the +located printer name +<p><br><li > If the share does not permit guest access and no username was +given, the username is set to the located printer name. +<p><br></ul> +<p><br>Note that the [printers] service MUST be printable - if you specify +otherwise, the server will refuse to load the configuration file. +<p><br>Typically the path specified would be that of a world-writable spool +directory with the sticky bit set on it. A typical [printers] entry +would look like this: +<p><br><pre> + + [printers] + path = /usr/spool/public + writable = no + guest ok = yes + printable = yes + +</pre> + +<p><br>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: +<p><br><pre> + alias|alias|alias|alias... +</pre> + +<p><br>Each alias should be an acceptable printer name for your printing +subsystem. In the <a href="smb.conf.5.html#global"><strong>[global]</strong></a> section, specify the new +file as your printcap. The server will then only recognise 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. +<p><br>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 +("|"). +<p><br>NOTE: On SYSV systems which use lpstat to determine what printers are +defined on the system you may be able to use <a href="smb.conf.5.html#printcapname"><strong>"printcap name = +lpstat"</strong></a> to automatically obtain a list of +printers. See the <a href="smb.conf.5.html#printcapname"><strong>"printcap name"</strong></a> option for +more detils. +<p><br></ul> +<p><br><a name="PARAMETERS"></a> +<h2>PARAMETERS</h2> + +<p><br>Parameters define the specific attributes of sections. +<p><br>Some parameters are specific to the <a href="smb.conf.5.html#global"><strong>[global]</strong></a> section +(eg., <a href="smb.conf.5.html#security"><strong>security</strong></a>). Some parameters are usable in +all sections (eg., <a href="smb.conf.5.html#createmode"><strong>create mode</strong></a>). All others are +permissible only in normal sections. For the purposes of the following +descriptions the <a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> and +<a href="smb.conf.5.html#printers"><strong>[printers]</strong></a> sections will be considered normal. +The letter <code>'G'</code> in parentheses indicates that a parameter is +specific to the <a href="smb.conf.5.html#global"><strong>[global]</strong></a> section. The letter <code>'S'</code> +indicates that a parameter can be specified in a service specific +section. Note that all <code>'S'</code> parameters can also be specified in the +<a href="smb.conf.5.html#global"><strong>[global]</strong></a> section - in which case they will define +the default behaviour for all services. +<p><br>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. +<p><br><a name="VARIABLESUBSTITUTIONS"></a> +<h2>VARIABLE SUBSTITUTIONS</h2> + +<p><br>Many of the strings that are settable in the config file can take +substitutions. For example the option <a href="smb.conf.5.html#path"><strong><code>"path = +/tmp/%u"</code></strong></a> would be interpreted as <code>"path = /tmp/john"</code> if +the user connected with the username john. +<p><br>These substitutions are mostly noted in the descriptions below, but +there are some general substitutions which apply whenever they might +be relevant. These are: +<p><br><ul> +<p><br><a name="percentS"></a> +<li > <strong>%S</strong> = the name of the current service, if any. +<p><br><a name="percentP"></a> +<li > <strong>%P</strong> = the root directory of the current service, if any. +<p><br><a name="percentu"></a> +<li > <strong>%u</strong> = user name of the current service, if any. +<p><br><a name="percentg"></a> +<li > <strong>%g</strong> = primary group name of <a href="smb.conf.5.html#percentu"><strong>%u</strong></a>. +<p><br><a name="percentU"></a> +<li > <strong>%U</strong> = session user name (the user name that +the client wanted, not necessarily the same as the one they got). +<p><br><a name="percentG"></a> +<li > <strong>%G</strong> = primary group name of <a href="smb.conf.5.html#percentU"><strong>%U</strong></a>. +<p><br><a name="percentH"></a> +<li > <strong>%H</strong> = the home directory of the user given by <a href="smb.conf.5.html#percentu"><strong>%u</strong></a>. +<p><br><a name="percentv"></a> +<li > <strong>%v</strong> = the Samba version. +<p><br><a name="percenth"></a> +<li > <strong>%h</strong> = the internet hostname that Samba is running on. +<p><br><a name="percentm"></a> +<li > <strong>%m</strong> = the NetBIOS name of the client machine (very useful). +<p><br><a name="percentL"></a> +<li > <strong>%L</strong> = the NetBIOS name of the server. This allows you to change your +config based on what the client calls you. Your server can have a "dual +personality". +<p><br><a name="percentM"></a> +<li > <strong>%M</strong> = the internet name of the client machine. +<p><br><a name="percentN"></a> +<li > <strong>%N</strong> = the name of your NIS home directory server. This is +obtained from your NIS auto.map entry. If you have not compiled Samba +with the <strong>--with-automount</strong> option then this value will be the same +as <a href="smb.conf.5.html#percentL"><strong>%L</strong></a>. +<p><br><a name="percentp"></a> +<li > <strong>%p</strong> = the path of the service's home directory, obtained from your NIS +auto.map entry. The NIS auto.map entry is split up as "%N:%p". +<p><br><a name="percentR"></a> +<li > <strong>%R</strong> = the selected protocol level after protocol +negotiation. It can be one of CORE, COREPLUS, LANMAN1, LANMAN2 or NT1. +<p><br><a name="percentd"></a> +<li > <strong>%d</strong> = The process id of the current server process. +<p><br><a name="percenta"></a> +<li > <strong>%a</strong> = the architecture of the remote +machine. Only some are recognised, and those may not be 100% +reliable. It currently recognises Samba, WfWg, WinNT and +Win95. Anything else will be known as "UNKNOWN". If it gets it wrong +then sending a level 3 log to <a href="mailto:samba-bugs@samba.anu.edu.au"><em>samba-bugs@samba.anu.edu.au</em></a> +should allow it to be fixed. +<p><br><a name="percentI"></a> +<li > <strong>%I</strong> = The IP address of the client machine. +<p><br><a name="percentT"></a> +<li > <strong>%T</strong> = the current date and time. +<p><br></ul> +<p><br>There are some quite creative things that can be done with these +substitutions and other smb.conf options. +<p><br><a name="NAMEMANGLING"></a> +<h2>NAME MANGLING</h2> + +<p><br>Samba supports <em>"name mangling"</em> so that DOS and Windows clients can +use files that don't conform to the 8.3 format. It can also be set to +adjust the case of 8.3 format filenames. +<p><br>There are several options that control the way mangling is performed, +and they are grouped here rather than listed separately. For the +defaults look at the output of the testparm program. +<p><br>All of these options can be set separately for each service (or +globally, of course). +<p><br>The options are: +<p><br><a name="manglecaseoption"></a> +<strong>"mangle case = yes/no"</strong> controls if names that have characters that +aren't of the "default" case are mangled. For example, if this is yes +then a name like <code>"Mail"</code> would be mangled. Default <em>no</em>. +<p><br><a name="casesensitiveoption"></a> +<strong>"case sensitive = yes/no"</strong> controls whether filenames are case +sensitive. If they aren't then Samba must do a filename search and +match on passed names. Default <em>no</em>. +<p><br><a name="defaultcaseoption"></a> +<strong>"default case = upper/lower"</strong> controls what the default case is for new +filenames. Default <em>lower</em>. +<p><br><a name="preservecaseoption"></a> +<strong>"preserve case = yes/no"</strong> controls if new files are created with the +case that the client passes, or if they are forced to be the <code>"default"</code> +case. Default <em>Yes</em>. +<p><br><a name="shortpreservecaseoption"></a> +<p><br><strong>"short preserve case = yes/no"</strong> controls if new files which conform +to 8.3 syntax, that is all in upper case and of suitable length, are +created upper case, or if they are forced to be the <code>"default"</code> +case. This option can be use with <a href="smb.conf.5.html#preservecaseoption"><strong>"preserve case = +yes"</strong></a> to permit long filenames to retain their +case, while short names are lowered. Default <em>Yes</em>. +<p><br>By default, Samba 2.0 has the same semantics as a Windows NT +server, in that it is case insensitive but case preserving. +<p><br><a name="NOTEABOUTUSERNAMEPASSWORDVALIDATION"></a> +<h2>NOTE ABOUT USERNAME/PASSWORD VALIDATION</h2> + +<p><br>There are a number of ways in which a user can connect to a +service. The server follows the following steps in determining if it +will allow a connection to a specified service. If all the steps fail +then the connection request is rejected. If one of the steps pass then +the following steps are not checked. +<p><br>If the service is marked <a href="smb.conf.5.html#guestonly"><strong>"guest only = yes"</strong></a> then +steps 1 to 5 are skipped. +<p><br><ol> +<p><br><li> Step 1: If the client has passed a username/password pair and +that username/password pair is validated by the UNIX system's password +programs then the connection is made as that username. Note that this +includes the <code>\\server\service%username</code> method of passing a +username. +<p><br><li> Step 2: If the client has previously registered a username with +the system and now supplies a correct password for that username then +the connection is allowed. +<p><br><li> Step 3: The client's netbios name and any previously used user +names are checked against the supplied password, if they match then +the connection is allowed as the corresponding user. +<p><br><li> Step 4: If the client has previously validated a +username/password pair with the server and the client has passed the +validation token then that username is used. This step is skipped if +<a href="smb.conf.5.html#revalidate"><strong>"revalidate = yes"</strong></a> for this service. +<p><br><li> Step 5: If a <a href="smb.conf.5.html#user"><strong>"user = "</strong></a> field is given in the +smb.conf file for the service and the client has supplied a password, +and that password matches (according to the UNIX system's password +checking) with one of the usernames from the <a href="smb.conf.5.html#user"><strong>user=</strong></a> +field then the connection is made as the username in the +<a href="smb.conf.5.html#user"><strong>"user="</strong></a> line. If one of the username in the +<a href="smb.conf.5.html#user"><strong>user=</strong></a> list begins with a <code>'@'</code> then that name +expands to a list of names in the group of the same name. +<p><br><li> Step 6: If the service is a guest service then a connection is +made as the username given in the <a href="smb.conf.5.html#guestaccount"><strong>"guest account +="</strong></a> for the service, irrespective of the supplied +password. +<p><br></ol> +<p><br><a name="COMPLETELISTOFGLOBALPARAMETERS"></a> +<h2>COMPLETE LIST OF GLOBAL PARAMETERS</h2> + +<p><br>Here is a list of all global parameters.

name="EXPLANATIONOFEACHPARAMETER"></a> +<h2>EXPLANATION OF EACH PARAMETER</h2> + +<p><br><ul> +<p><br><a name="adminusers"></a> +<li><strong><strong>admin users (S)</strong></strong> +<p><br>This is a list of users who will be granted administrative privileges +on the share. This means that they will do all file operations as the +super-user (root). +<p><br>You should use this option very carefully, as any user in this list +will be able to do anything they like on the share, irrespective of +file permissions. +<p><br><strong>Default:</strong> <br> +<code> no admin users</code> +<p><br><strong>Example:</strong> <br> +<code> admin users = jason</code> +<p><br><a name="allowhosts"></a> +<li><strong><strong>allow hosts (S)</strong></strong> +<p><br>A synonym for this parameter is <a href="smb.conf.5.html#hostsallow"><strong>'hosts allow'</strong></a> +<p><br>This parameter is a comma, space, or tab delimited set of hosts which +are permitted to access a service. +<p><br>If specified in the <a href="smb.conf.5.html#global"><strong>[global]</strong></a> section then it will +apply to all services, regardless of whether the individual service +has a different setting. +<p><br>You can specify the hosts by name or IP number. For example, you could +restrict access to only the hosts on a Class C subnet with something +like <code>"allow hosts = 150.203.5."</code>. The full syntax of the list is +described in the man page <strong>hosts_access (5)</strong>. Note that this man +page may not be present on your system, so a brief description will +be given here also. +<p><br><em>NOTE:</em> IF you wish to allow the <a href="smbpasswd.html.8"><strong>smbpasswd +(8)</strong></a> program to be run by local users to change +their Samba passwords using the local <a href="smbd.8.html"><strong>smbd (8)</strong></a> +daemon, then you <em>MUST</em> ensure that the localhost is listed in your +<strong>allow hosts</strong> list, as <a href="smbpasswd.html.8"><strong>smbpasswd (8)</strong></a> runs +in client-server mode and is seen by the local +<a href="smbd.8.html"><strong>smbd</strong></a> process as just another client. +<p><br>You can also specify hosts by network/netmask pairs and by netgroup +names if your system supports netgroups. The <em>EXCEPT</em> keyword can also +be used to limit a wildcard list. The following examples may provide +some help: +<p><br><strong>Example 1</strong>: allow localhost and all IPs in 150.203.*.* except one +<p><br><code> hosts allow = localhost, 150.203. EXCEPT 150.203.6.66</code> +<p><br><strong>Example 2</strong>: allow localhost and hosts that match the given network/netmask +<p><br><code> hosts allow = localhost, 150.203.15.0/255.255.255.0</code> +<p><br><strong>Example 3</strong>: allow a localhost plus a couple of hosts +<p><br><code> hosts allow = localhost, lapland, arvidsjaur</code> +<p><br><strong>Example 4</strong>: allow only hosts in NIS netgroup "foonet" or localhost, but +deny access from one particular host +<p><br><code> hosts allow = @foonet, localhost</code> +<code> hosts deny = pirate</code> +<p><br>Note that access still requires suitable user-level passwords. +<p><br>See <a href="testparm.1.html"><strong>testparm (1)</strong></a> for a way of testing your +host access to see if it does what you expect. +<p><br><strong>Default:</strong> +<code> none (i.e., all hosts permitted access)</code> +<p><br><strong>Example:</strong> +<code> allow hosts = 150.203.5. localhost myhost.mynet.edu.au</code> +<p><br><a name="alternatepermissions"></a> +<li><strong><strong>alternate permissions (S)</strong></strong> +<p><br>This is a deprecated parameter. It no longer has any effect in Samba2.0. +In previous versions of Samba it affected the way the DOS "read only" +attribute was mapped for a file. In Samba2.0 a file is marked "read only" +if the UNIX file does not have the 'w' bit set for the owner of the file, +regardless if the owner of the file is the currently logged on user or not. +<p><br><a name="announceas"></a> +<li><strong><strong>announce as (G)</strong></strong> +<p><br>This specifies what type of server <a href="nmbd.8.html"><strong>nmbd</strong></a> will +announce itself as, to a network neighborhood browse list. By default +this is set to Windows NT. The valid options are : "NT", "Win95" or +"WfW" meaining Windows NT, Windows 95 and Windows for Workgroups +respectively. Do not change this parameter unless you have a specific +need to stop Samba appearing as an NT server as this may prevent Samba +servers from participating as browser servers correctly. +<p><br><strong>Default:</strong> +<code> announce as = NT</code> +<p><br><strong>Example</strong> +<code> announce as = Win95</code> +<p><br><a name="announceversion"></a> +<li><strong><strong>announce version (G)</strong></strong> +<p><br>This specifies the major and minor version numbers that nmbd will use +when announcing itself as a server. The default is 4.2. Do not change +this parameter unless you have a specific need to set a Samba server +to be a downlevel server. +<p><br><strong>Default:</strong> +<code> announce version = 4.2</code> +<p><br><strong>Example:</strong> +<code> announce version = 2.0</code> +<p><br><a name="autoservices"></a> +<li><strong><strong>auto services (G)</strong></strong> +<p><br>This is a list of services that you want to be automatically added to +the browse lists. This is most useful for homes and printers services +that would otherwise not be visible. +<p><br>Note that if you just want all printers in your printcap file loaded +then the <a href="smb.conf.5.html#loadprinters"><strong>"load printers"</strong></a> option is easier. +<p><br><strong>Default:</strong> +<code> no auto services</code> +<p><br><strong>Example:</strong> +<code> auto services = fred lp colorlp</code> +<p><br><a name="available"></a> +<li><strong><strong>available (S)</strong></strong> +<p><br>This parameter lets you <em>'turn off'</em> a service. If <code>'available = no'</code>, +then <em>ALL</em> attempts to connect to the service will fail.

If oplocks are enabled on a share, +Visual C++ uses two different time reading calls to check if a file +has changed since it was last read. One of these calls uses a +one-second granularity, the other uses a two second granularity. As +the two second call rounds any odd second down, then if the file has a +timestamp of an odd number of seconds then the two timestamps will not +match and Visual C++ will keep reporting the file has changed. Setting +this option causes the two timestamps to match, and Visual C++ is +happy. +<p><br><strong>Default:</strong> +<code> dos filetime resolution = False</code> +<p><br><strong>Example:</strong> +<code> dos filetime resolution = True</code> +<p><br><a name="dosfiletimes"></a> +<li><strong><strong>dos filetimes (S)</strong></strong> +<p><br>Under DOS and Windows, if a user can write to a file they can change +the timestamp on it.

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. +<p><br>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. +<p><br>However, Unix time semantics mean that the create time reported by +Samba will be updated whenever a file is created or deleted in the +directory. NMAKE therefore finds all object files in the object +directory bar the last one built are out of date compared to the +directory and rebuilds them. Enabling this option ensures directories +always predate their contents and an NMAKE build will proceed as +expected. +<p><br><strong>Default:</strong> +<code> fake directory create times = False</code> +<p><br><strong>Example:</strong> +<code> fake directory create times = True</code> +<p><br><a name="fakeoplocks"></a> +<li><strong><strong>fake oplocks (S)</strong></strong> +<p><br>Oplocks are the way that SMB clients get permission from a server to +locally cache file operations. If a server grants an oplock +(opportunistic lock) then the client is free to assume that it is the +only one accessing the file and it will aggressively cache file +data. With some oplock types the client may even cache file open/close +operations. This can give enormous performance benefits. +<p><br>When you set <code>"fake oplocks = yes"</code> <a href="smbd.8.html"><strong>smbd</strong></a> will +always grant oplock requests no matter how many clients are using the +file. +<p><br>It is generally much better to use the real <a href="smb.conf.5.html#oplocks"><strong>oplocks</strong></a> +support rather than this parameter. +<p><br>If you enable this option on all read-only shares or shares that you +know will only be accessed from one client at a time such as +physically read-only media like CDROMs, you will see a big performance +improvement on many operations. If you enable this option on shares +where multiple clients may be accessing the files read-write at the +same time you can get data corruption. Use this option carefully! +<p><br>This option is disabled by default. +<p><br><a name="followsymlinks"></a> +<li><strong><strong>follow symlinks (S)</strong></strong> +<p><br>This parameter allows the Samba administrator to stop +<a href="smbd.8.html"><strong>smbd</strong></a> from following symbolic links in a +particular share. Setting this parameter to <em>"No"</em> prevents any file +or directory that is a symbolic link from being followed (the user +will get an error). This option is very useful to stop users from +adding a symbolic link to <code>/etc/pasword</code> in their home directory for +instance.

The spool file name is +generated automatically by the server, the printer name is discussed +below. +<p><br>The full path name will be used for the filename if <code>"%s"</code> is not +preceded by a <code>'/'</code>.

This is +because you are trusting the PC to supply the correct username. It is +very easy to get a PC to supply a false username. I recommend that the +<strong>use rhosts</strong> option be only used if you really know what you are +doing. +<p><br><strong>Default:</strong> +<code> use rhosts = no</code> +<p><br><strong>Example:</strong> +<code> use rhosts = yes</code> +<p><br><a name="user"></a> +<li><strong><strong>user (S)</strong></strong> +<p><br>Synonym for <a href="smb.conf.5.html#username"><strong>"username"</strong></a>. +<p><br><a name="users"></a> +<li><strong><strong>users (S)</strong></strong> +<p><br>Synonym for <a href="smb.conf.5.html#username"><strong>"username"</strong></a>. +<p><br><a name="username"></a> +<li><strong><strong>username (S)</strong></strong> +<p><br>Multiple users may be specified in a comma-delimited list, in which +case the supplied password will be tested against each username in +turn (left to right). +<p><br>The <strong>username=</strong> 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 <code>\\server\share%user</code> +syntax instead. +<p><br>The <strong>username=</strong> 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 username= 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. +<p><br>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. +<p><br>To restrict a service to a particular set of users you can use the +<a href="smb.conf.5.html#validusers"><strong>"valid users="</strong></a> parameter. +<p><br>If any of the usernames begin with a <code>'@'</code> 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. +<p><br>If any of the usernames begin with a <code>'+'</code> 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. +<p><br>If any of the usernames begin with a <code>'&'</code> then the name will be +looked up only in the yp netgroups database (if Samba is compiled with +netgroup support) and will expand to a list of all users in the +netgroup group of that name. +<p><br>Note that searching though a groups database can take quite some time, +and some clients may time out during the search. +<p><br>See the section <a href="smb.conf.5.html#NOTEABOUTUSERNAMEPASSWORDVALIDATION"><strong>"NOTE ABOUT USERNAME/PASSWORD +VALIDATION"</strong></a> for more +information on how this parameter determines access to the services. +<p><br><strong>Default:</strong> +<code> The guest account if a guest service, else the name of the service.</code> +<p><br><strong>Examples:</strong> +<pre> + + username = fred + username = fred, mary, jack, jane, @users, @pcgroup + +</pre> + +<p><br><a name="usernamelevel"></a> +<li><strong><strong>username level (G)</strong></strong> +<p><br>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. +<p><br>If this parameter is set to non-zero the behaviour changes. This +parameter is a number that specifies the number of uppercase +combinations to try whilst trying to determine the UNIX user name. The +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 <code>"AstrangeUser"</code>. +<p><br><strong>Default:</strong> +<code> username level = 0</code> +<p><br><strong>Example:</strong> +<code> username level = 5</code> +<p><br><a name="usernamemap"></a> +<li><strong><strong>username map (G)</strong></strong> +<p><br>This option allows you to 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. +<p><br>The map file is parsed line by line. Each line should contain a single +UNIX username on the left then a <code>'='</code> 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 <code>'*'</code> is a wildcard +and matches any name. Each line of the map file may be up to 1023 +characters long. +<p><br>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 <code>'='</code> +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. +<p><br>If any line begins with a <code>'#'</code> or a <code>';'</code> then it is ignored +<p><br>If any line begins with an <code>'!'</code> 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 <code>'!'</code> is most +useful when you have a wildcard mapping line later in the file. +<p><br>For example to map from the name <code>"admin"</code> or <code>"administrator"</code> to +the UNIX name <code>"root"</code> you would use: +<p><br><code> root = admin administrator</code> +<p><br>Or to map anyone in the UNIX group <code>"system"</code> to the UNIX name +<code>"sys"</code> you would use: +<p><br><code> sys = @system</code> +<p><br>You can have as many mappings as you like in a username map file. +<p><br>If your system supports the NIS NETGROUP option then the netgroup +database is checked before the <code>/etc/group</code> database for matching +groups. +<p><br>You can map Windows usernames that have spaces in them by using double +quotes around the name. For example: +<p><br><code> tridge = "Andrew Tridgell"</code> +<p><br>would map the windows username <code>"Andrew Tridgell"</code> to the unix +username tridge. +<p><br>The following example would map mary and fred to the unix user sys, +and map the rest to guest. Note the use of the <code>'!'</code> to tell Samba +to stop processing if it gets a match on that line. +<p><br><pre> + + !sys = mary fred + guest = * + +</pre> + +<p><br>Note that the remapping is applied to all occurrences of +usernames. Thus if you connect to <code>"\\server\fred"</code> and <code>"fred"</code> +is remapped to <code>"mary"</code> then you will actually be connecting to +<code>"\\server\mary"</code> and will need to supply a password suitable for +<code>"mary"</code> not <code>"fred"</code>. The only exception to this is the username +passed to the <a href="smb.conf.5.html#passwordserver"><strong>"password server"</strong></a> (if you have +one). The password server will receive whatever username the client +supplies without modification. +<p><br>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. +<p><br><strong>Default:</strong> +<code> no username map</code> +<p><br><strong>Example:</strong> +<code> username map = /usr/local/samba/lib/users.map</code> +<p><br><a name="validchars"></a> +<li><strong><strong>valid chars (S)</strong></strong> +<p><br>The option allows you to specify additional characters that should be +considered valid by the server in filenames. This is particularly +useful for national character sets, such as adding u-umlaut or a-ring. +<p><br>The option takes a list of characters in either integer or character +form with spaces between them. If you give two characters with a colon +between them then it will be taken as an lowercase:uppercase pair. +<p><br>If you have an editor capable of entering the characters into the +config file then it is probably easiest to use this method. Otherwise +you can specify the characters in octal, decimal or hexadecimal form +using the usual C notation. +<p><br>For example to add the single character <code>'Z'</code> to the charset (which +is a pointless thing to do as it's already there) you could do one of +the following +<p><br><pre> + + valid chars = Z + valid chars = z:Z + valid chars = 0132:0172 + +</pre> + +<p><br>The last two examples above actually add two characters, and alter the +uppercase and lowercase mappings appropriately. +<p><br>Note that you MUST specify this parameter after the <a href="smb.conf.5.html#clientcodepage"><strong>"client +code page"</strong></a> parameter if you have both set. If +<a href="smb.conf.5.html#clientcodepage"><strong>"client code page"</strong></a> is set after the +<strong>"valid chars"</strong> parameter the <strong>"valid chars"</strong> settings will be +overwritten. +<p><br>See also the <a href="smb.conf.5.html#clientcodepage"><strong>"client code page"</strong></a> parameter. +<p><br><strong>Default:</strong> +<pre> + + Samba defaults to using a reasonable set of valid characters + for english systems + +</pre> + +<p><br><strong>Example</strong> +<code> valid chars = 0345:0305 0366:0326 0344:0304</code> +<p><br>The above example allows filenames to have the swedish characters in +them. +<p><br>NOTE: It is actually quite difficult to correctly produce a <strong>"valid +chars"</strong> line for a particular system. To automate the process +<a href="mailto:tino@augsburg.net"><em>tino@augsburg.net</em></a> has written a package called <strong>"validchars"</strong> +which will automatically produce a complete <strong>"valid chars"</strong> line for +a given client system.

Names starting with <code>'@'</code>, <code>'+'</code> and <code>'&'</code> are +interpreted using the same rules as described in the <a href="smb.conf.5.html#invalidusers"><strong>"invalid +users"</strong></a> parameter. +<p><br>If this is empty (the default) then any user can login. If a username +is in both this list and the <a href="smb.conf.5.html#invalidusers"><strong>"invalid users"</strong></a> +list then access is denied for that user. +<p><br>The current servicename is substituted for +<a href="smb.conf.5.html#percentS"><strong>"%S"</strong></a>.

Each entry in the list must be separated by a <code>'/'</code>, +which allows spaces to be included in the entry. <code>'*'</code> and <code>'?'</code> +can be used to specify multiple files or directories as in DOS +wildcards. +<p><br>Each entry must be a unix path, not a DOS path and must <em>*not*</em> include the +unix directory separator <code>'/'</code>. +<p><br>Note that the <a href="smb.conf.5.html#casesensitive"><strong>"case sensitive"</strong></a> option is +applicable in vetoing files. +<p><br>One feature of the veto files parameter that it is important to be +aware of, is that if a directory contains nothing but files that match +the veto files parameter (which means that Windows/DOS clients cannot +ever see them) is deleted, the veto files within that directory *are +automatically deleted* along with it, if the user has UNIX permissions +to do so. +<p><br>Setting this parameter will affect the performance of Samba, as it +will be forced to check all files and directories for a match as they +are scanned. +<p><br>See also <a href="smb.conf.5.html#hidefiles"><strong>"hide files"</strong></a> and <a href="smb.conf.5.html#casesensitive"><strong>"case +sensitive"</strong></a>. +<p><br><strong>Default:</strong> +<code> No files or directories are vetoed.</code> +<p><br><strong>Examples:</strong> +<p><br>Example 1. +<p><br><pre> + + + Veto any files containing the word Security, + any ending in .tmp, and any directory containing the + word root. + + veto files = /*Security*/*.tmp/*root*/ + +</pre> + +<p><br>Example 2. +<p><br><pre> + + Veto the Apple specific files that a NetAtalk server + creates. + + veto files = /.AppleDouble/.bin/.AppleDesktop/Network Trash Folder/ + +</pre> + +<p><br><a name="vetooplockfiles"></a> +<li><strong><strong>veto oplock files (S)</strong></strong> +<p><br>This parameter is only valid when the <a href="smb.conf.5.html#oplocks"><strong>"oplocks"</strong></a> +parameter is turned on for a share. It allows the Samba administrator +to selectively turn off the granting of oplocks on selected files that +match a wildcarded list, similar to the wildcarded list used in the +<a href="smb.conf.5.html#vetofiles"><strong>"veto files"</strong></a> parameter. +<p><br><strong>Default:</strong> +<code> No files are vetoed for oplock grants.</code> +<p><br><strong>Examples:</strong> +<p><br>You might want to do this on files that you know will be heavily +contended for by clients. A good example of this is in the NetBench +SMB benchmark program, which causes heavy client contention for files +ending in <code>".SEM"</code>. To cause Samba not to grant oplocks on these +files you would use the line (either in the <a href="smb.conf.5.html#global"><strong>[global]</strong></a> +section or in the section for the particular NetBench share : +<p><br><code> veto oplock files = /*.SEM/</code> +<p><br><a name="volume"></a> +<li><strong><strong>volume (S)</strong></strong> +<p><br>This allows you to override the volume label returned for a +share.

For this reason you should +probably keep your service names down to eight characters in length. +<p><br>Use of the <a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> and <a href="smb.conf.5.html#printers"><strong>[printers]</strong></a> +special sections make life for an administrator easy, but the various +combinations of default attributes can be tricky.
