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 necessary. -<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 - writeable = 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] - writeable = 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-writeable 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 - writeable = 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 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. -<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 details. -<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 -(e.g., <a href="smb.conf.5.html#security"><strong>security</strong></a>). Some parameters are usable in -all sections (e.g., <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 behavior 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 recognized, and those may not be 100% -reliable. It currently recognizes 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.org"><em>samba-bugs@samba.org</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" meaning 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. Such failures -are logged. -<p><br><strong>Default:</strong> -<code> available = yes</code> -<p><br><strong>Example:</strong> -<code> available = no</code> -<p><br><a name="bindinterfacesonly"></a> -<li><strong><strong>bind interfaces only (G)</strong></strong> -<p><br>This global parameter allows the Samba admin to limit what interfaces -on a machine will serve smb requests. If affects file service -<a href="smbd.8.html"><strong>smbd</strong></a> and name service <a href="nmbd.8.html"><strong>nmbd</strong></a> -in slightly different ways. -<p><br>For name service it causes <a href="nmbd.8.html"><strong>nmbd</strong></a> to bind to ports -137 and 138 on the interfaces listed in the -<a href="smb.conf.5.html#interfaces"><strong>'interfaces'</strong></a> -parameter. <a href="nmbd.8.html"><strong>nmbd</strong></a> also binds to the 'all -addresses' interface (0.0.0.0) on ports 137 and 138 for the purposes -of reading broadcast messages.

For more -details on setting up this feature see the file DOMAINS.txt in the -Samba documentation directory <code>docs/</code> shipped with the source code. -<p><br>Note that Win95/98 Domain logons are <em>NOT</em> the same as Windows -NT Domain logons. NT Domain logons require a Primary Domain Controller -(PDC) for the Domain. It is intended that in a future release Samba -will be able to provide this functionality for Windows NT clients -also. -<p><br><strong>Default:</strong> -<code> domain logons = no</code> -<p><br><a name="domainmaster"></a> -<li><strong><strong>domain master (G)</strong></strong> -<p><br>Tell <a href="nmbd.8.html"><strong>nmbd</strong></a> to enable WAN-wide browse list -collation. Setting this option causes <a href="nmbd.8.html"><strong>nmbd</strong></a> to -claim a special domain specific NetBIOS name that identifies it as a -domain master browser for its given -<a href="smb.conf.5.html#workgroup"><strong>workgroup</strong></a>. Local master browsers in the same -<a href="smb.conf.5.html#workgroup"><strong>workgroup</strong></a> on broadcast-isolated subnets will give -this <a href="nmbd.8.html"><strong>nmbd</strong></a> their local browse lists, and then -ask <a href="smbd.8.html"><strong>smbd</strong></a> for a complete copy of the browse list -for the whole wide area network. Browser clients will then contact -their local master browser, and will receive the domain-wide browse -list, instead of just the list for their broadcast-isolated subnet. -<p><br>Note that Windows NT Primary Domain Controllers expect to be able to -claim this <a href="smb.conf.5.html#workgroup"><strong>workgroup</strong></a> specific special NetBIOS -name that identifies them as domain master browsers for that -<a href="smb.conf.5.html#workgroup"><strong>workgroup</strong></a> by default (i.e. there is no way to -prevent a Windows NT PDC from attempting to do this). This means that -if this parameter is set and <a href="nmbd.8.html"><strong>nmbd</strong></a> claims the -special name for a <a href="smb.conf.5.html#workgroup"><strong>workgroup</strong></a> before a Windows NT -PDC is able to do so then cross subnet browsing will behave strangely -and may fail. -<p><br><strong>Default:</strong> -<code> domain master = no</code> -<p><br><a name="dontdescend"></a> -<li><strong><strong>dont descend (S)</strong></strong> -<p><br>There are certain directories on some systems (e.g., the <code>/proc</code> tree -under Linux) that are either not of interest to clients or are -infinitely deep (recursive). This parameter allows you to specify a -comma-delimited list of directories that the server should always show -as empty. -<p><br>Note that Samba can be very fussy about the exact format of the "dont -descend" entries. For example you may need <code>"./proc"</code> instead of -just <code>"/proc"</code>. Experimentation is the best policy :-) -<p><br><strong>Default:</strong> -<code> none (i.e., all directories are OK to descend)</code> -<p><br><strong>Example:</strong> -<code> dont descend = /proc,/dev</code> -<p><br><a name="dosfiletimeresolution"></a> -<li><strong><strong>dos filetime resolution (S)</strong></strong> -<p><br>Under the DOS and Windows FAT filesystem, the finest granularity on -time resolution is two seconds. Setting this parameter for a share -causes Samba to round the reported time down to the nearest two second -boundary when a query call that requires one second resolution is made -to <a href="smbd.8.html"><strong>smbd</strong></a>. -<p><br>This option is mainly used as a compatibility option for Visual C++ -when used against Samba shares. 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. Under POSIX semantics, only the owner of the file -or root may change the timestamp. By default, Samba runs with POSIX -semantics and refuses to change the timestamp on a file if the user -smbd is acting on behalf of is not the file owner. Setting this option -to True allows DOS semantics and smbd will change the file timestamp as -DOS requires. -<p><br><strong>Default:</strong> -<code> dos filetimes = False</code> -<p><br><strong>Example:</strong> -<code> dos filetimes = True</code> -<p><br><a name="encryptpasswords"></a> -<li><strong><strong>encrypt passwords (G)</strong></strong> -<p><br>This boolean controls whether encrypted passwords will be negotiated -with the client. Note that Windows NT 4.0 SP3 and above and also -Windows 98 will by default expect encrypted passwords unless a -registry entry is changed. To use encrypted passwords in Samba see the -file ENCRYPTION.txt in the Samba documentation directory <code>docs/</code> -shipped with the source code. -<p><br>In order for encrypted passwords to work correctly -<a href="smbd.8.html"><strong>smbd</strong></a> must either have access to a local -<a href="smbpasswd.5.html"><strong>smbpasswd (5)</strong></a> file (see the -<a href="smbpasswd.8.html"><strong>smbpasswd (8)</strong></a> program for information on -how to set up and maintain this file), or set the -<a href="smb.conf.5.html#security"><strong>security=</strong></a> parameter to either -<a href="smb.conf.5.html#securityequalserver"><strong>"server"</strong></a> or -<a href="smb.conf.5.html#securityequaldomain"><strong>"domain"</strong></a> which causes -<a href="smbd.8.html"><strong>smbd</strong></a> to authenticate against another server. -<p><br><a name="exec"></a> -<li><strong><strong>exec (S)</strong></strong> -<p><br>This is a synonym for <a href="smb.conf.5.html#preexec"><strong>preexec</strong></a>. -<p><br><a name="fakedirectorycreatetimes"></a> -<li><strong><strong>fake directory create times (S)</strong></strong> -<p><br>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. -<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/passwd</code> in their home directory for -instance. However it will slow filename lookups down slightly. -<p><br>This option is enabled (i.e. <a href="smbd.8.html"><strong>smbd</strong></a> will follow -symbolic links) by default. -<p><br><a name="forcecreatemode"></a> -<li><strong><strong>force create mode (S)</strong></strong> -<p><br>This parameter specifies a set of UNIX mode bit permissions that will -<em>*always*</em> be set on a file created by Samba. This is done by -bitwise 'OR'ing these bits onto the mode bits of a file that is being -created. The default for this parameter is (in octal) 000. The modes -in this parameter are bitwise 'OR'ed onto the file mode after the mask -set in the <a href="smb.conf.5.html#createmask"><strong>"create mask"</strong></a> parameter is applied. -<p><br>See also the parameter <a href="smb.conf.5.html#createmask"><strong>"create mask"</strong></a> for details -on masking mode bits on created files. -<p><br><strong>Default:</strong> -<code> force create mode = 000</code> -<p><br><strong>Example:</strong> -<code> force create mode = 0755</code> -<p><br>would force all created files to have read and execute permissions set -for 'group' and 'other' as well as the read/write/execute bits set for -the 'user'. -<p><br><a name="forcedirectorymode"></a> -<li><strong><strong>force directory mode (S)</strong></strong> -<p><br>This parameter specifies a set of UNIX mode bit permissions that will -<em>*always*</em> be set on a directory created by Samba.

The default for this parameter is (in octal) 0000 which -will not add any extra permission bits to a created directory. This -operation is done after the mode mask in the parameter -<a href="smb.conf.5.html#directorymask"><strong>"directory mask"</strong></a> is applied. -<p><br>See also the parameter <a href="smb.conf.5.html#directorymask"><strong>"directory mask"</strong></a> for -details on masking mode bits on created directories. -<p><br><strong>Default:</strong> -<code> force directory mode = 000</code> -<p><br><strong>Example:</strong> -<code> force directory mode = 0755</code> -<p><br>would force all created directories to have read and execute -permissions set for 'group' and 'other' as well as the -read/write/execute bits set for the 'user'. -<p><br><a name="forcegroup"></a> -<li><strong><strong>force group (S)</strong></strong> -<p><br>This specifies a UNIX group name that will be assigned as the default -primary group for all users connecting to this service. This is useful -for sharing files by ensuring that all access to files on service will -use the named group for their permissions checking. Thus, by assigning -permissions for this group to the files and directories within this -service the Samba administrator can restrict or allow sharing of these -files. -<p><br><strong>Default:</strong> -<code> no forced group</code> -<p><br><strong>Example:</strong> -<code> force group = agroup</code> -<p><br><a name="forceuser"></a> -<li><strong><strong>force user (S)</strong></strong> -<p><br>This specifies a UNIX user name that will be assigned as the default -user for all users connecting to this service. This is useful for -sharing files. You should also use it carefully as using it -incorrectly can cause security problems. -<p><br>This user name only gets used once a connection is established. Thus -clients still need to connect as a valid user and supply a valid -password. Once connected, all file operations will be performed as the -<code>"forced user"</code>, no matter what username the client connected as. -<p><br>This can be very useful. -<p><br><strong>Default:</strong> -<code> no forced user</code> -<p><br><strong>Example:</strong> -<code> force user = auser</code> -<p><br><a name="fstype"></a> -<li><strong><strong>fstype (S)</strong></strong> -<p><br>This parameter allows the administrator to configure the string that -specifies the type of filesystem a share is using that is reported by -<a href="smbd.8.html"><strong>smbd</strong></a> when a client queries the filesystem type -for a share.

For example, under UNIX -it is common to use <code>".html"</code> for HTML files, whereas under -Windows/DOS <code>".htm"</code> is more commonly used. -<p><br>So to map <code>"html"</code> to <code>"htm"</code> you would use: -<p><br><code> mangled map = (*.html *.htm)</code> -<p><br>One very useful case is to remove the annoying <code>";1"</code> off the ends -of filenames on some CDROMS (only visible under some UNIXs).

Helpdesk services will -<em>*hate*</em> you if you set the <strong>"map to guest"</strong> parameter -this way :-). -<p><br></ul> -<p><br>Note that this parameter is needed to set up <strong>"Guest"</strong> share -services when using <a href="smb.conf.5.html#security"><strong>security</strong></a> modes other than -share. This is because in these modes the name of the resource being -requested is <em>*not*</em> sent to the server until after the server has -successfully authenticated the client so the server cannot make -authentication decisions at the correct time (connection to the -share) for <strong>"Guest"</strong> shares. -<p><br>For people familiar with the older Samba releases, this parameter -maps to the old compile-time setting of the GUEST_SESSSETUP value -in local.h. -<p><br><strong>Default:</strong> -<code> map to guest = Never</code> - <strong>Example</strong>: -<code> map to guest = Bad User</code> -<p><br><a name="maxconnections"></a> -<li><strong><strong>max connections (S)</strong></strong> -<p><br>This option allows the number of simultaneous connections to a service -to be limited.

In -particular: -<p><br><ul> -<p><br><li > <code>"%s"</code> = the filename containing the message. -<p><br><li > <code>"%t"</code> = the destination that the message was sent to (probably the server -name). -<p><br><li > <code>"%f"</code> = who the message is from. -<p><br></ul> -<p><br>You could make this command send mail, or whatever else takes your -fancy. Please let us know of any really interesting ideas you have. -<p><br>Here's a way of sending the messages as mail to root: -<p><br><code>message command = /bin/mail -s 'message from %f on %m' root < %s; rm %s</code> -<p><br>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.

For UNIX systems that use an -automounter, the user's home directory will often be mounted on a -workstation on demand from a remote server. -<p><br>When the Samba logon server is not the actual home directory server, -but is mounting the home directories via NFS then two network hops -would be required to access the users home directory if the logon -server told the client to use itself as the SMB server for home -directories (one over SMB and one over NFS). This can be very -slow. -<p><br>This option allows Samba to return the home share as being on a -different server to the logon server and as long as a Samba daemon is -running on the home directory server, it will be mounted on the Samba -client directly from the directory server. When Samba is returning the -home share to the client, it will consult the NIS map specified in -<a href="smb.conf.5.html#homedirmap"><strong>"homedir map"</strong></a> and return the server listed -there. -<p><br>Note that for this option to work there must be a working NIS -system and the Samba server with this option must also be a -<a href="smb.conf.5.html#domainlogons"><strong>logon server</strong></a>. -<p><br><strong>Default:</strong> -<code> nis homedir = false</code> -<p><br><strong>Example:</strong> -<code> nis homedir = true</code> -<p><br><a name="ntpipesupport"></a> -<li><strong><strong>nt pipe support (G)</strong></strong> -<p><br>This boolean parameter controls whether <a href="smbd.8.html"><strong>smbd</strong></a> -will allow Windows NT clients to connect to the NT SMB specific -<code>IPC$</code> pipes.

By -default this option is disabled so a client can supply a username to -be used by the server. -<p><br>Note that this also means Samba won't try to deduce usernames from the -service name. This can be annoying for the <a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> -section. To get around this you could use "<a href="smb.conf.5.html#user"><strong>user</strong></a> = -<a href="smb.conf.5.html#percentS"><strong>%S</strong></a>" which means your <a href="smb.conf.5.html#user"><strong>"user"</strong></a> list -will be just the service name, which for home directories is the name -of the user. -<p><br>See also the <a href="smb.conf.5.html#user"><strong>user</strong></a> parameter. -<p><br><strong>Default:</strong> -<code> only user = False</code> -<p><br><strong>Example:</strong> -<code> only user = True</code> -<p><br><a name="oplocks"></a> -<li><strong><strong>oplocks (S)</strong></strong> -<p><br>This boolean option tells smbd whether to issue oplocks (opportunistic -locks) to file open requests on this share.

The server will not remove the spool file, so whatever -command you specify should remove the spool file when it has been -processed, otherwise you will need to manually remove old spool files. -<p><br>The print command is simply a text string. It will be used verbatim, -with two exceptions: All occurrences of <code>"%s"</code> will be replaced by -the appropriate spool file name, and all occurrences of <code>"%p"</code> will -be replaced by the appropriate printer name. 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>. If you don't like this (it can stuff up some -lpq output) then use <code>"%f"</code> instead. Any occurrences of <code>"%f"</code> get -replaced by the spool filename without the full path at the front. -<p><br>The print command <em>MUST</em> contain at least one occurrence of <code>"%s"</code> -or <code>"%f"</code> - the <code>"%p"</code> is optional. At the time a job is -submitted, if no printer name is supplied the <code>"%p"</code> will be -silently removed from the printer command. -<p><br>If specified in the <a href="smb.conf.5.html#global"><strong>"[global]"</strong></a> section, the print -command given will be used for any printable service that does not -have its own print command specified. -<p><br>If there is neither a specified print command for a printable service -nor a global print command, spool files will be created but not -processed and (most importantly) not removed. -<p><br>Note that printing may fail on some UNIXs from the <code>"nobody"</code> -account.

Note that <code>';'</code> is the usual -separator for command in shell scripts. -<p><br><code>print command = echo Printing %s >> /tmp/print.log; lpr -P %p %s; rm %s</code> -<p><br>You may have to vary this command considerably depending on how you -normally print files on your system.

This is the default for systems that define SYSV -at configure time in Samba (this includes most System V based -systems). If <strong>"printcap name"</strong> is set to <strong>lpstat</strong> on these systems -then Samba will launch <code>"lpstat -v"</code> and attempt to parse the output -to obtain a printer list. -<p><br>A minimal printcap file would look something like this: -<p><br><pre> - - print1|My Printer 1 - print2|My Printer 2 - print3|My Printer 3 - print4|My Printer 4 - print5|My Printer 5 - -</pre> - -<p><br>where the <code>'|'</code> separates aliases of a printer. The fact that the -second alias has a space in it gives a hint to Samba that it's a -comment. -<p><br><em>NOTE</em>: Under AIX the default printcap name is -<code>"/etc/qconfig"</code>.

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 "no" (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 -performance problems that people have reported with the new Windows98 -explorer shell file copies. -<p><br>See also the <a href="smb.conf.5.html#syncalways"><strong>"sync always"</strong></a> parameter. -<p><br><strong>Default:</strong> -<code> strict sync = no</code> -<p><br><strong>Example:</strong> -<code> strict sync = yes</code> -<p><br><a name="stripdot"></a> -<li><strong><strong>strip dot (G)</strong></strong> -<p><br>This is a boolean that controls whether to strip trailing dots off -UNIX filenames.

If this is -false then the server will be guided by the client's request in each -write call (clients can set a bit indicating that a particular write -should be synchronous). If this is true then every write will be -followed by a fsync() call to ensure the data is written to disk. -Note that the <a href="smb.conf.5.html#strictsync"><strong>"strict sync"</strong></a> parameter must be -set to <code>"yes"</code> in order for this parameter to have any affect. -<p><br>See also the <a href="smb.conf.5.html#strictsync"><strong>"strict sync"</strong></a> parameter. -<p><br><strong>Default:</strong> -<code> sync always = no</code> -<p><br><strong>Example:</strong> -<code> sync always = yes</code> -<p><br><a name="syslog"></a> -<li><strong><strong>syslog (G)</strong></strong> -<p><br>This parameter maps how Samba debug messages are logged onto the -system syslog logging levels. Samba debug level zero maps onto syslog -LOG_ERR, debug level one maps onto LOG_WARNING, debug level two maps -to LOG_NOTICE, debug level three maps onto LOG_INFO.

If this is set to true the -program specified in the <a href="smb.conf.5.html#passwdprogram"><strong>"passwd program"</strong></a> -parameter is called <em>*AS ROOT*</em> - to allow the new UNIX password to be -set without access to the old UNIX password (as the SMB password has -change code has no access to the old password cleartext, only the -new). By default this is set to <code>"false"</code>. -<p><br>See also <a href="smb.conf.5.html#passwdprogram"><strong>"passwd program"</strong></a>, <a href="smb.conf.5.html#passwdchat"><strong>"passwd -chat"</strong></a>. -<p><br><strong>Default:</strong> -<code> unix password sync = False</code> -<p><br><strong>Example:</strong> -<code> unix password sync = True</code> -<p><br><a name="unixrealname"></a> -<li><strong><strong>unix realname (G)</strong></strong> -<p><br>This boolean parameter when set causes samba to supply the real name -field from the unix password file to the client.

This option allows a -site to migrate from plaintext password authentication (users -authenticate with plaintext password over the wire, and are checked -against a UNIX account database) to encrypted password authentication -(the SMB challenge/response authentication mechanism) without forcing -all users to re-enter their passwords via smbpasswd at the time the -change is made. This is a convenience option to allow the change over -to encrypted passwords to be made over a longer period. Once all users -have encrypted representations of their passwords in the smbpasswd -file this parameter should be set to <code>"off"</code>. -<p><br>In order for this parameter to work correctly the <a href="smb.conf.5.html#encryptpasswords"><strong>"encrypt -passwords"</strong></a> parameter must be set to <code>"no"</code> when -this parameter is set to <code>"yes"</code>. -<p><br>Note that even when this parameter is set a user authenticating to -smbd must still enter a valid password in order to connect correctly, -and to update their hashed (smbpasswd) passwords. -<p><br><strong>Default:</strong> -<code> update encrypted = no</code> -<p><br><strong>Example:</strong> -<code> update encrypted = yes</code> -<p><br><a name="userhosts"></a> -<li><strong><strong>use rhosts (G)</strong></strong> -<p><br>If this global parameter is a true, it specifies that the UNIX users -<code>".rhosts"</code> file in their home directory will be read to find the -names of hosts and users who will be allowed access without specifying -a password. -<p><br>NOTE: The use of <strong>use rhosts</strong> can be a major security hole. 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 behavior 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 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. Look in the examples/validchars/ subdirectory -of your Samba source code distribution for this package. -<p><br><a name="validusers"></a> -<li><strong><strong>valid users (S)</strong></strong> -<p><br>This is a list of users that should be allowed to login to this -service. 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>. This is useful in the -<a href="smb.conf.5.html#homes"><strong>[homes]</strong></a> section. -<p><br>See also <a href="smb.conf.5.html#invalidusers"><strong>"invalid users"</strong></a>. -<p><br><strong>Default:</strong> -<code> No valid users list. (anyone can login)</code> -<p><br><strong>Example:</strong> -<code> valid users = greg, @pcusers</code> -<p><br><a name="vetofiles"></a> -<li><strong><strong>veto files(S)</strong></strong> -<p><br>This is a list of files and directories that are neither visible nor -accessible. 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. Useful for CDROMs with installation programs that insist on a -particular volume label. -<p><br>The default is the name of the share. -<p><br><a name="widelinks"></a> -<li><strong><strong>wide links (S)</strong></strong> -<p><br>This parameter controls whether or not links in the UNIX file system -may be followed by the server. Links that point to areas within the -directory tree exported by the server are always allowed; this -parameter controls access only to areas that are outside the directory -tree being exported. -<p><br><strong>Default:</strong> -<code> wide links = yes</code> -<p><br><strong>Example:</strong> -<code> wide links = no</code> -<p><br><a name="winsproxy"></a> -<li><strong><strong>wins proxy (G)</strong></strong> -<p><br>This is a boolean that controls if <a href="nmbd.8.html"><strong>nmbd</strong></a> will -respond to broadcast name queries on behalf of other hosts. You may -need to set this to <code>"yes"</code> for some older clients. -<p><br><strong>Default:</strong> -<code> wins proxy = no</code> -<p><br><a name="winsserver"></a> -<li><strong><strong>wins server (G)</strong></strong> -<p><br>This specifies the DNS name (or IP address) of the WINS server that -<a href="nmbd.8.html"><strong>nmbd</strong></a> should register with. If you have a WINS -server on your network then you should set this to the WINS servers -name. -<p><br>You should point this at your WINS server if you have a -multi-subnetted network. -<p><br><em>NOTE</em>. You need to set up Samba to point to a WINS server if you -have multiple subnets and wish cross-subnet browsing to work correctly. -<p><br>See the documentation file BROWSING.txt in the docs/ directory of your -Samba source distribution. -<p><br><strong>Default:</strong> -<code> wins server = </code> -<p><br><strong>Example:</strong> -<code> wins server = 192.9.200.1</code> -<p><br><a name="winssupport"></a> -<li><strong><strong>wins support (G)</strong></strong> -<p><br>This boolean controls if the <a href="nmbd.8.html"><strong>nmbd</strong></a> process in -Samba will act as a WINS server. You should not set this to true -unless you have a multi-subnetted network and you wish a particular -<a href="nmbd.8.html"><strong>nmbd</strong></a> to be your WINS server. Note that you -should <em>*NEVER*</em> set this to true on more than one machine in your -network. -<p><br><strong>Default:</strong> -<code> wins support = no</code> -<p><br><a name="workgroup"></a> -<li><strong><strong>workgroup (G)</strong></strong> -<p><br>This controls what workgroup your server will appear to be in when -queried by clients. Note that this parameter also controls the Domain -name used with the <a href="smb.conf.5.html#securityequaldomain"><strong>"security=domain"</strong></a> -setting. -<p><br><strong>Default:</strong> -<code> set at compile time to WORKGROUP</code> -<p><br><strong>Example:</strong> - workgroup = MYGROUP -<p><br><a name="writable"></a> -<li><strong><strong>writable (S)</strong></strong> -<p><br>Synonym for <a href="smb.conf.5.html#writeable"><strong>"writeable"</strong></a> for people who can't spell :-). -<p><br><a name="writelist"></a> -<li><strong><strong>write list (S)</strong></strong> -<p><br>This is a list of users that are given read-write access to a -service. If the connecting user is in this list then they will be -given write access, no matter what the <a href="smb.conf.5.html#readonly"><strong>"read only"</strong></a> -option is set to. The list can include group names using the @group -syntax. -<p><br>Note that if a user is in both the read list and the write list then -they will be given write access. -<p><br>See also the <a href="smb.conf.5.html#readlist"><strong>"read list"</strong></a> option. -<p><br><strong>Default:</strong> -<code> write list = <empty string></code> -<p><br><strong>Example:</strong> -<code> write list = admin, root, @staff</code> -<p><br><a name="writeok"></a> -<li><strong><strong>write ok (S)</strong></strong> -<p><br>Synonym for <a href="smb.conf.5.html#writeable"><strong>writeable</strong></a>. -<p><br><a name="writeraw"></a> -<li><strong><strong>write raw (G)</strong></strong> -<p><br>This parameter controls whether or not the server will support raw -writes SMB's when transferring data from clients. You should never -need to change this parameter. -<p><br><strong>Default:</strong> -<code> write raw = yes</code> -<p><br><a name="writeable"></a> -<li><strong><strong>writeable</strong></strong> -<p><br>An inverted synonym is <a href="smb.conf.5.html#readonly"><strong>"read only"</strong></a>. -<p><br>If this parameter is <code>"no"</code>, then users of a service may not create -or modify files in the service's directory. -<p><br>Note that a printable service <a href="smb.conf.5.html#printable"><strong>("printable = yes")</strong></a> -will <em>*ALWAYS*</em> allow writing to the directory (user privileges -permitting), but only via spooling operations. -<p><br><strong>Default:</strong> -<code> writeable = no</code> -<p><br><strong>Examples:</strong> -<pre> - - read only = no - writeable = yes - write ok = yes - -</pre> - -<p><br><a name="WARNINGS"></a> -<h2>WARNINGS</h2> - -<p><br>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. -<p><br>On a similar note, many clients - especially DOS clients - limit -service names to eight characters. <a href="smbd.8.html"><strong>Smbd</strong></a> 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. -<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.
