+This book is a collection of HOWTOs added to Samba documentation over the years.
+Samba is always under development, and so is its' documentation. This release of the

+
+The Samba-Team would like to express sincere thanks to the many people who have with
+or without their knowledge contributed to this update. The size and scope of this
+project would not have been possible without significant community contribution. A not
+insignificant number of ideas for inclusion (if not content itself) has been obtained
+from a number of Unofficial HOWTOs - to each such author a big &quot;Thank-you&quot; is also offered.
+Please keep publishing your Unofficial HOWTO's - they are a source of inspiration and
+application knowledge that is most to be desired by many Samba users and administrators.

+This book is a collection of HOWTOs added to Samba documentation over the years.
+Samba is always under development, and so is its' documentation. This release of the
+documentation represents a major revision or layout as well as contents.
+The most recent version of this document can be found at
+<a href="http://www.samba.org/" target="_top">http://www.samba.org/</a>
+on the &quot;Documentation&quot; page. Please send updates to
+<a href="mailto:jelmer@samba.org" target="_top">Jelmer Venrooij</a>,
+<a href="mailto:jht@samba.org" target="_top">John Terpstra</a> or
+<a href="mailto:jerry@samba.org" target="_top">Gerald (Jerry) Carter</a>.
+</p><p>
+The Samba-Team would like to express sincere thanks to the many people who have with
+or without their knowledge contributed to this update. The size and scope of this
+project would not have been possible without significant community contribution. A not
+insignificant number of ideas for inclusion (if not content itself) has been obtained
+from a number of Unofficial HOWTOs - to each such author a big &quot;Thank-you&quot; is also offered.
+Please keep publishing your Unofficial HOWTO's - they are a source of inspiration and
+application knowledge that is most to be desired by many Samba users and administrators.

+Samba is a file and print server for Windows-based clients using TCP/IP as the underlying
transport protocol. In fact, it can support any SMB/CIFS-enabled client. One of Samba's big
strengths is that you can use it to blend your mix of Windows and Linux machines together
without requiring a separate Windows NT/2000/2003 Server. Samba is actively being developed
-by a global team of about 30 active programmers and was originally developed by Andrew Tridgell.</P

+Once long ago, there was a buzzword referred to as DCE/RPC. This stood for Distributed
Computing Environment/Remote Procedure Calls and conceptually was a good idea. It was
originally developed by Apollo/HP as NCA 1.0 (Network Computing Architecture) and only
ran over UDP. When there was a need to run it over TCP so that it would be compatible
with DECnet 3.0, it was redesigned, submitted to The Open Group, and officially became
known as DCE/RPC. Microsoft came along and decided, rather than pay $20 per seat to
license this technology, to reimplement DCE/RPC themselves as MSRPC. From this, the

run SMB (i.e., transport) over several different protocols; many different implementations
arose as a result, including NBIPX (NetBIOS over IPX, NwLnkNb, or NWNBLink) and NBT
(NetBIOS over TCP/IP, or NetBT). As the years passed, NBT became the most common form

->2.6.2. Locking</A
-></H3
-><P
->One area which sometimes causes trouble is locking.</P
-><P
->There are two types of locking which need to be
- performed by a SMB server. The first is "record locking"
- which allows a client to lock a range of bytes in a open file.
- The second is the "deny modes" that are specified when a file
- is open.</P
-><P
->Record locking semantics under Unix is very
- different from record locking under Windows. Versions
- of Samba before 2.2 have tried to use the native
- fcntl() unix system call to implement proper record
- locking between different Samba clients. This can not
- be fully correct due to several reasons. The simplest
- is the fact that a Windows client is allowed to lock a
- byte range up to 2^32 or 2^64, depending on the client
- OS. The unix locking only supports byte ranges up to
- 2^31. So it is not possible to correctly satisfy a
- lock request above 2^31. There are many more
- differences, too many to be listed here.</P
-><P
->Samba 2.2 and above implements record locking
- completely independent of the underlying unix
- system. If a byte range lock that the client requests
- happens to fall into the range 0-2^31, Samba hands
- this request down to the Unix system. All other locks
- can not be seen by unix anyway.</P
-><P
->Strictly a SMB server should check for locks before
- every read and write call on a file. Unfortunately with the
- way fcntl() works this can be slow and may overstress the
- rpc.lockd. It is also almost always unnecessary as clients
- are supposed to independently make locking calls before reads
- and writes anyway if locking is important to them. By default
- Samba only makes locking calls when explicitly asked
- to by a client, but if you set "strict locking = yes" then it will
- make lock checking calls on every read and write. </P
-><P
->You can also disable by range locking completely
- using "locking = no". This is useful for those shares that
- don't support locking or don't need it (such as cdroms). In
- this case Samba fakes the return codes of locking calls to
- tell clients that everything is OK.</P
-><P
->The second class of locking is the "deny modes". These
- are set by an application when it opens a file to determine
- what types of access should be allowed simultaneously with
- its open. A client may ask for DENY_NONE, DENY_READ, DENY_WRITE
- or DENY_ALL. There are also special compatibility modes called
- DENY_FCB and DENY_DOS.</P

->3.1. Discussion</A
-></H2
-><P
->Firstly, all MS Windows networking is based on SMB (Server Message
-Block) based messaging. SMB messaging may be implemented using NetBIOS or
-without NetBIOS. Samba implements NetBIOS by encapsulating it over TCP/IP.
-MS Windows products can do likewise. NetBIOS based networking uses broadcast
-messaging to affect browse list management. When running NetBIOS over
-TCP/IP this uses UDP based messaging. UDP messages can be broadcast or unicast.</P
-><P
->Normally, only unicast UDP messaging can be forwarded by routers. The
-<B
-CLASS="COMMAND"
->remote announce</B
->
-parameter to smb.conf helps to project browse announcements
-to remote network segments via unicast UDP. Similarly, the
-<B
-CLASS="COMMAND"
->remote browse sync</B
-> parameter of <TT
-CLASS="FILENAME"
->smb.conf</TT
->
-implements browse list collation using unicast UDP.</P
-><P
->Secondly, in those networks where Samba is the only SMB server technology
-wherever possible <SPAN
-CLASS="APPLICATION"
->nmbd</SPAN
-> should be configured on one (1) machine as the WINS
-server. This makes it easy to manage the browsing environment. If each network
-segment is configured with it's own Samba WINS server, then the only way to
-get cross segment browsing to work is by using the
-<B
-CLASS="COMMAND"
->remote announce</B
-> and the <B
-CLASS="COMMAND"
->remote browse sync</B
->
-parameters to your <TT
-CLASS="FILENAME"
->smb.conf</TT
-> file.</P
-><P
->If only one WINS server is used for an entire multi-segment network then
-the use of the <B
-CLASS="COMMAND"
->remote announce</B
-> and the
-<B
-CLASS="COMMAND"
->remote browse sync</B
-> parameters should NOT be necessary.</P
-><P
->As of Samba 3 WINS replication is being worked on. The bulk of the code has
-been committed, but it still needs maturation.</P
-><P
->Right now samba WINS does not support MS-WINS replication. This means that
-when setting up Samba as a WINS server there must only be one <SPAN
-CLASS="APPLICATION"
->nmbd</SPAN
-> configured
-as a WINS server on the network. Some sites have used multiple Samba WINS
-servers for redundancy (one server per subnet) and then used
-<B
-CLASS="COMMAND"
->remote browse sync</B
-> and <B
-CLASS="COMMAND"
->remote announce</B
->
-to affect browse list collation across all
-segments. Note that this means clients will only resolve local names,
-and must be configured to use DNS to resolve names on other subnets in
-order to resolve the IP addresses of the servers they can see on other
-subnets. This setup is not recommended, but is mentioned as a practical
-consideration (ie: an 'if all else fails' scenario).</P
-><P
->Lastly, take note that browse lists are a collection of unreliable broadcast
-messages that are repeated at intervals of not more than 15 minutes. This means
-that it will take time to establish a browse list and it can take up to 45
-minutes to stabilise, particularly across network segments.</P

-></H2
-><P
->As stated above, MS Windows machines register their NetBIOS names
-(i.e.: the machine name for each service type in operation) on start
-up. Also, as stated above, the exact method by which this name registration
-takes place is determined by whether or not the MS Windows client/server
-has been given a WINS server address, whether or not LMHOSTS lookup
-is enabled, or if DNS for NetBIOS name resolution is enabled, etc.</P
-><P
->In the case where there is no WINS server all name registrations as
-well as name lookups are done by UDP broadcast. This isolates name
-resolution to the local subnet, unless LMHOSTS is used to list all
-names and IP addresses. In such situations Samba provides a means by
-which the samba server name may be forcibly injected into the browse
-list of a remote MS Windows network (using the
-<B
-CLASS="COMMAND"
->remote announce</B
-> parameter).</P
-><P
->Where a WINS server is used, the MS Windows client will use UDP
-unicast to register with the WINS server. Such packets can be routed
-and thus WINS allows name resolution to function across routed networks.</P
-><P
->During the startup process an election will take place to create a
-local master browser if one does not already exist. On each NetBIOS network
-one machine will be elected to function as the domain master browser. This
-domain browsing has nothing to do with MS security domain control.
-Instead, the domain master browser serves the role of contacting each local
-master browser (found by asking WINS or from LMHOSTS) and exchanging browse
-list contents. This way every master browser will eventually obtain a complete
-list of all machines that are on the network. Every 11-15 minutes an election
-is held to determine which machine will be the master browser. By the nature of
-the election criteria used, the machine with the highest uptime, or the
-most senior protocol version, or other criteria, will win the election
-as domain master browser.</P
-><P
->Clients wishing to browse the network make use of this list, but also depend
-on the availability of correct name resolution to the respective IP
-address/addresses. </P
-><P
->Any configuration that breaks name resolution and/or browsing intrinsics
-will annoy users because they will have to put up with protracted
-inability to use the network services.</P
-><P
->Samba supports a feature that allows forced synchonisation
-of browse lists across routed networks using the <B
-CLASS="COMMAND"
->remote
-browse sync</B
-> parameter in the <TT
-CLASS="FILENAME"
->smb.conf</TT
-> file.
-This causes Samba to contact the local master browser on a remote network and
-to request browse list synchronisation. This effectively bridges
-two networks that are separated by routers. The two remote
-networks may use either broadcast based name resolution or WINS
-based name resolution, but it should be noted that the <B
-CLASS="COMMAND"
->remote
-browse sync</B
-> parameter provides browse list synchronisation - and
-that is distinct from name to address resolution, in other
-words, for cross subnet browsing to function correctly it is
-essential that a name to address resolution mechanism be provided.

-></H2
-><P
->Use of WINS (either Samba WINS _or_ MS Windows NT Server WINS) is highly
-recommended. Every NetBIOS machine registers it's name together with a
-name_type value for each of of several types of service it has available.
-eg: It registers it's name directly as a unique (the type 0x03) name.
-It also registers it's name if it is running the lanmanager compatible
-server service (used to make shares and printers available to other users)
-by registering the server (the type 0x20) name.</P
-><P
->All NetBIOS names are up to 15 characters in length. The name_type variable
-is added to the end of the name - thus creating a 16 character name. Any
-name that is shorter than 15 characters is padded with spaces to the 15th
-character. ie: All NetBIOS names are 16 characters long (including the
-name_type information).</P
-><P
->WINS can store these 16 character names as they get registered. A client
-that wants to log onto the network can ask the WINS server for a list
-of all names that have registered the NetLogon service name_type. This saves
-broadcast traffic and greatly expedites logon processing. Since broadcast
-name resolution can not be used across network segments this type of
-information can only be provided via WINS _or_ via statically configured
-<TT
-CLASS="FILENAME"
->lmhosts</TT
-> files that must reside on all clients in the
-absence of WINS.</P
-><P
->WINS also serves the purpose of forcing browse list synchronisation by all
-LMB's. LMB's must synchronise their browse list with the DMB (domain master
-browser) and WINS helps the LMB to identify it's DMB. By definition this
-will work only within a single workgroup. Note that the domain master browser
-has NOTHING to do with what is referred to as an MS Windows NT Domain. The
-later is a reference to a security environment while the DMB refers to the
-master controller for browse list information only.</P
-><P
->Use of WINS will work correctly only if EVERY client TCP/IP protocol stack
-has been configured to use the WINS server/s. Any client that has not been
-configured to use the WINS server will continue to use only broadcast based
-name registration so that WINS may NEVER get to know about it. In any case,

->The unix and SMB password encryption techniques seem similar
- on the surface. This similarity is, however, only skin deep. The unix
- scheme typically sends clear text passwords over the network when
- logging in. This is bad. The SMB encryption scheme never sends the
- cleartext password over the network but it does store the 16 byte
- hashed values on disk. This is also bad. Why? Because the 16 byte hashed
- values are a "password equivalent". You cannot derive the user's
- password from them, but they could potentially be used in a modified
- client to gain access to a server. This would require considerable
- technical knowledge on behalf of the attacker but is perfectly possible.
- You should thus treat the data stored in whatever
- passdb backend you use (smbpasswd file, ldap, mysql) as though it contained the
- cleartext passwords of all your users. Its contents must be kept
- secret, and the file should be protected accordingly.</P
-><P
->Ideally we would like a password scheme which neither requires
- plain text passwords on the net or on disk. Unfortunately this
- is not available as Samba is stuck with being compatible with
- other SMB systems (WinNT, WfWg, Win95 etc). </P

+Through the use of PAM (Pluggable Authentication Modules) and nsswitch
(the name service switcher) the source of authentication may reside on
another server. We would be inclined to call this the authentication server.
This means that the samba server may use the local Unix/Linux system
password database (/etc/passwd or /etc/shadow), may use a local smbpasswd
file (/etc/samba/smbpasswd or /usr/local/samba/lib/private/smbpasswd), or

+MS Windows 2000 and later can be configured to operate with NO NetBIOS
+over TCP/IP. Samba-3 and later also supports this mode of operation.
+When the use of NetBIOS over TCP/IP has been disabled then the primary
+means for resolution of MS Windows machine names is via DNS and Active Directory.
+The following information assumes that your site is running NetBIOS over TCP/IP.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2862996"></a>What is Browsing?</h2></div></div><p>
+To most people browsing means that they can see the MS Windows and Samba servers
+in the Network Neighborhood, and when the computer icon for a particular server is
+clicked, it opens up and shows the shares and printers available on the target server.
+</p><p>
+What seems so simple is in fact a very complex interaction of different technologies.
+The technologies (or methods) employed in making all of this work includes:
+</p><table class="simplelist" border="0" summary="Simple list"><tr><td>MS Windows machines register their presence to the network</td></tr><tr><td>Machines announce themselves to other machines on the network</td></tr><tr><td>One or more machine on the network collates the local announcements</td></tr><tr><td>The client machine finds the machine that has the collated list of machines</td></tr><tr><td>The client machine is able to resolve the machine names to IP addresses</td></tr><tr><td>The client machine is able to connect to a target machine</td></tr></table><p>
+The samba application that controls/manages browse list management and name resolution is
+called <tt>nmbd</tt>. The configuration parameters involved in nmbd's operation are:
+</p><pre class="programlisting">
+ Browsing options:
+ -----------------
+ * os level
+ lm announce
+ lm interval
+ * preferred master
+ * local master
+ * domain master
+ browse list
+ enhanced browsing
+
+ Name Resolution Method:
+ -----------------------
+ * name resolve order
+
+ WINS options:
+ -------------
+ dns proxy
+ wins proxy
+ * wins server
+ * wins support
+ wins hook
+</pre><p>
+WINS Server and WINS Support are mutually exclusive options. Those marked with an '*' are
+the only options that commonly MAY need to be modified. Even if not one of these parameters
+is set nmbd will still do it's job.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2863646"></a>Discussion</h2></div></div><p>
+Firstly, all MS Windows networking is based on SMB (Server Message
+Block) based messaging. SMB messaging may be implemented using NetBIOS or
+without NetBIOS. Samba implements NetBIOS by encapsulating it over TCP/IP.
+MS Windows products can do likewise. NetBIOS based networking uses broadcast
+messaging to affect browse list management. When running NetBIOS over
+TCP/IP this uses UDP based messaging. UDP messages can be broadcast or unicast.
+</p><p>
+Normally, only unicast UDP messaging can be forwarded by routers. The
+<b>remote announce</b>
+parameter to smb.conf helps to project browse announcements
+to remote network segments via unicast UDP. Similarly, the
+<b>remote browse sync</b> parameter of <tt>smb.conf</tt>
+implements browse list collation using unicast UDP.
+</p><p>
+Secondly, in those networks where Samba is the only SMB server technology
+wherever possible <tt>nmbd</tt> should be configured on one (1) machine as the WINS
+server. This makes it easy to manage the browsing environment. If each network
+segment is configured with it's own Samba WINS server, then the only way to
+get cross segment browsing to work is by using the
+<b>remote announce</b> and the <b>remote browse sync</b>
+parameters to your <tt>smb.conf</tt> file.
+</p><p>
+If only one WINS server is used for an entire multi-segment network then
+the use of the <b>remote announce</b> and the
+<b>remote browse sync</b> parameters should NOT be necessary.
+</p><p>
+As of Samba 3 WINS replication is being worked on. The bulk of the code has
+been committed, but it still needs maturation.
+</p><p>
+Right now samba WINS does not support MS-WINS replication. This means that
+when setting up Samba as a WINS server there must only be one <tt>nmbd</tt> configured
+as a WINS server on the network. Some sites have used multiple Samba WINS
+servers for redundancy (one server per subnet) and then used
+<b>remote browse sync</b> and <b>remote announce</b>
+to affect browse list collation across all
+segments. Note that this means clients will only resolve local names,
+and must be configured to use DNS to resolve names on other subnets in
+order to resolve the IP addresses of the servers they can see on other
+subnets. This setup is not recommended, but is mentioned as a practical
+consideration (ie: an 'if all else fails' scenario).
+</p><p>
+Lastly, take note that browse lists are a collection of unreliable broadcast
+messages that are repeated at intervals of not more than 15 minutes. This means
+that it will take time to establish a browse list and it can take up to 45
+minutes to stabilise, particularly across network segments.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2863809"></a>How Browsing Functions</h2></div></div><p>
+As stated above, MS Windows machines register their NetBIOS names
+(ie: the machine name for each service type in operation) on start
+up. Also, as stated above, the exact method by which this name registration
+takes place is determined by whether or not the MS Windows client/server
+has been given a WINS server address, whether or not LMHOSTS lookup
+is enabled, or if DNS for NetBIOS name resolution is enabled, etc.
+</p><p>
+In the case where there is no WINS server all name registrations as
+well as name lookups are done by UDP broadcast. This isolates name
+resolution to the local subnet, unless LMHOSTS is used to list all
+names and IP addresses. In such situations Samba provides a means by
+which the samba server name may be forcibly injected into the browse
+list of a remote MS Windows network (using the
+<b>remote announce</b> parameter).
+</p><p>
+Where a WINS server is used, the MS Windows client will use UDP
+unicast to register with the WINS server. Such packets can be routed
+and thus WINS allows name resolution to function across routed networks.
+</p><p>
+During the startup process an election will take place to create a
+local master browser if one does not already exist. On each NetBIOS network
+one machine will be elected to function as the domain master browser. This
+domain browsing has nothing to do with MS security domain control.
+Instead, the domain master browser serves the role of contacting each local
+master browser (found by asking WINS or from LMHOSTS) and exchanging browse
+list contents. This way every master browser will eventually obtain a complete
+list of all machines that are on the network. Every 11-15 minutes an election
+is held to determine which machine will be the master browser. By the nature of
+the election criteria used, the machine with the highest uptime, or the
+most senior protocol version, or other criteria, will win the election
+as domain master browser.
+</p><p>
+Clients wishing to browse the network make use of this list, but also depend
+on the availability of correct name resolution to the respective IP
+address/addresses.
+</p><p>
+Any configuration that breaks name resolution and/or browsing intrinsics
+will annoy users because they will have to put up with protracted
+inability to use the network services.
+</p><p>
+Samba supports a feature that allows forced synchonisation
+of browse lists across routed networks using the <b>remote
+browse sync</b> parameter in the <tt>smb.conf</tt> file.
+This causes Samba to contact the local master browser on a remote network and
+to request browse list synchronisation. This effectively bridges
+two networks that are separated by routers. The two remote
+networks may use either broadcast based name resolution or WINS
+based name resolution, but it should be noted that the <b>remote
+browse sync</b> parameter provides browse list synchronisation - and
+that is distinct from name to address resolution, in other
+words, for cross subnet browsing to function correctly it is
+essential that a name to address resolution mechanism be provided.
+This mechanism could be via DNS, <tt>/etc/hosts</tt>,
+and so on.
+</p><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2863936"></a>Setting up WORKGROUP Browsing</h3></div></div><p>
+To set up cross subnet browsing on a network containing machines
+in up to be in a WORKGROUP, not an NT Domain you need to set up one
+Samba server to be the Domain Master Browser (note that this is *NOT*
+the same as a Primary Domain Controller, although in an NT Domain the
+same machine plays both roles). The role of a Domain master browser is
+to collate the browse lists from local master browsers on all the
+subnets that have a machine participating in the workgroup. Without
+one machine configured as a domain master browser each subnet would
+be an isolated workgroup, unable to see any machines on any other
+subnet. It is the presense of a domain master browser that makes
+cross subnet browsing possible for a workgroup.
+</p><p>
+In an WORKGROUP environment the domain master browser must be a
+Samba server, and there must only be one domain master browser per
+workgroup name. To set up a Samba server as a domain master browser,
+set the following option in the [global] section of the <tt>smb.conf</tt> file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = yes
+</pre><p>
+</p><p>
+The domain master browser should also preferrably be the local master
+browser for its own subnet. In order to achieve this set the following
+options in the [global] section of the <tt>smb.conf</tt> file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = yes
+ local master = yes
+ preferred master = yes
+ os level = 65
+</pre><p>
+</p><p>
+The domain master browser may be the same machine as the WINS
+server, if you require.
+</p><p>
+Next, you should ensure that each of the subnets contains a
+machine that can act as a local master browser for the
+workgroup. Any MS Windows NT/2K/XP/2003 machine should be
+able to do this, as will Windows 9x machines (although these
+tend to get rebooted more often, so it's not such a good idea
+to use these). To make a Samba server a local master browser
+set the following options in the [global] section of the
+<tt>smb.conf</tt> file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = no
+ local master = yes
+ preferred master = yes
+ os level = 65
+</pre><p>
+</p><p>
+Do not do this for more than one Samba server on each subnet,
+or they will war with each other over which is to be the local
+master browser.
+</p><p>
+The <b>local master</b> parameter allows Samba to act as a
+local master browser. The <b>preferred master</b> causes nmbd
+to force a browser election on startup and the <b>os level</b>
+parameter sets Samba high enough so that it should win any browser elections.
+</p><p>
+If you have an NT machine on the subnet that you wish to
+be the local master browser then you can disable Samba from
+becoming a local master browser by setting the following
+options in the <b>[global]</b> section of the
+<tt>smb.conf</tt> file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = no
+ local master = no
+ preferred master = no
+ os level = 0
+</pre><p>
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2864124"></a>Setting up DOMAIN Browsing</h3></div></div><p>
+If you are adding Samba servers to a Windows NT Domain then
+you must not set up a Samba server as a domain master browser.
+By default, a Windows NT Primary Domain Controller for a Domain
+name is also the Domain master browser for that name, and many
+things will break if a Samba server registers the Domain master
+browser NetBIOS name (<i><tt>DOMAIN</tt></i>&lt;1B&gt;)
+with WINS instead of the PDC.
+</p><p>
+For subnets other than the one containing the Windows NT PDC
+you may set up Samba servers as local master browsers as
+described. To make a Samba server a local master browser set
+the following options in the <b>[global]</b> section
+of the <tt>smb.conf</tt> file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = no
+ local master = yes
+ preferred master = yes
+ os level = 65
+</pre><p>
+</p><p>
+If you wish to have a Samba server fight the election with machines
+on the same subnet you may set the <b>os level</b> parameter
+to lower levels. By doing this you can tune the order of machines that
+will become local master browsers if they are running. For
+more details on this see the section <a href="#browse-force-master" title="Forcing samba to be the master">
+Forcing samba to be the master browser</a>
+below.
+</p><p>
+If you have Windows NT machines that are members of the domain
+on all subnets, and you are sure they will always be running then
+you can disable Samba from taking part in browser elections and
+ever becoming a local master browser by setting following options
+in the <b>[global]</b> section of the <tt>smb.conf</tt>
+file :
+</p><p>
+</p><pre class="programlisting">
+ domain master = no
+ local master = no
+ preferred master = no
+ os level = 0
+</pre><p>
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="browse-force-master"></a>Forcing samba to be the master</h3></div></div><p>
+Who becomes the <b>master browser</b> is determined by an election
+process using broadcasts. Each election packet contains a number of parameters
+which determine what precedence (bias) a host should have in the
+election. By default Samba uses a very low precedence and thus loses
+elections to just about anyone else.
+</p><p>
+If you want Samba to win elections then just set the <b>os level</b> global
+option in <tt>smb.conf</tt> to a higher number. It defaults to 0. Using 34
+would make it win all elections over every other system (except other
+samba systems!)
+</p><p>
+A <b>os level</b> of 2 would make it beat WfWg and Win95, but not MS Windows
+NT/2K Server. A MS Windows NT/2K Server domain controller uses level 32.
+</p><p>The maximum os level is 255</p><p>
+If you want samba to force an election on startup, then set the
+<b>preferred master</b> global option in <tt>smb.conf</tt> to &quot;yes&quot;. Samba will
+then have a slight advantage over other potential master browsers
+that are not preferred master browsers. Use this parameter with
+care, as if you have two hosts (whether they are windows 95 or NT or
+samba) on the same local subnet both set with <b>preferred master</b> to
+&quot;yes&quot;, then periodically and continually they will force an election
+in order to become the local master browser.
+</p><p>
+If you want samba to be a <b>domain master browser</b>, then it is
+recommended that you also set <b>preferred master</b> to &quot;yes&quot;, because
+samba will not become a domain master browser for the whole of your
+LAN or WAN if it is not also a local master browser on its own
+broadcast isolated subnet.
+</p><p>
+It is possible to configure two samba servers to attempt to become
+the domain master browser for a domain. The first server that comes
+up will be the domain master browser. All other samba servers will
+attempt to become the domain master browser every 5 minutes. They
+will find that another samba server is already the domain master
+browser and will fail. This provides automatic redundancy, should
+the current domain master browser fail.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2864390"></a>Making samba the domain master</h3></div></div><p>
+The domain master is responsible for collating the browse lists of
+multiple subnets so that browsing can occur between subnets. You can
+make samba act as the domain master by setting <b>domain master = yes</b>
+in <tt>smb.conf</tt>. By default it will not be a domain master.
+</p><p>
+Note that you should NOT set Samba to be the domain master for a
+workgroup that has the same name as an NT Domain.
+</p><p>
+When samba is the domain master and the master browser it will listen
+for master announcements (made roughly every twelve minutes) from local
+master browsers on other subnets and then contact them to synchronise
+browse lists.
+</p><p>
+If you want samba to be the domain master then I suggest you also set
+the <b>os level</b> high enough to make sure it wins elections, and set
+<b>preferred master</b> to &quot;yes&quot;, to get samba to force an election on
+startup.
+</p><p>
+Note that all your servers (including samba) and clients should be
+using a WINS server to resolve NetBIOS names. If your clients are only
+using broadcasting to resolve NetBIOS names, then two things will occur:
+</p><div class="orderedlist"><ol type="1"><li><p>
+ your local master browsers will be unable to find a domain master
+ browser, as it will only be looking on the local subnet.
+ </p></li><li><p>
+ if a client happens to get hold of a domain-wide browse list, and
+ a user attempts to access a host in that list, it will be unable to
+ resolve the NetBIOS name of that host.
+ </p></li></ol></div><p>
+If, however, both samba and your clients are using a WINS server, then:
+</p><div class="orderedlist"><ol type="1"><li><p>
+ your local master browsers will contact the WINS server and, as long as
+ samba has registered that it is a domain master browser with the WINS
+ server, your local master browser will receive samba's ip address
+ as its domain master browser.
+ </p></li><li><p>
+ when a client receives a domain-wide browse list, and a user attempts
+ to access a host in that list, it will contact the WINS server to
+ resolve the NetBIOS name of that host. as long as that host has
+ registered its NetBIOS name with the same WINS server, the user will
+ be able to see that host.
+ </p></li></ol></div></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2864538"></a>Note about broadcast addresses</h3></div></div><p>
+If your network uses a &quot;0&quot; based broadcast address (for example if it
+ends in a 0) then you will strike problems. Windows for Workgroups
+does not seem to support a 0's broadcast and you will probably find
+that browsing and name lookups won't work.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2864555"></a>Multiple interfaces</h3></div></div><p>
+Samba now supports machines with multiple network interfaces. If you

+The <b>remote announce</b> parameter of

+that all the NetBIOS names on a network get announced to a remote network.
+The syntax of the <b>remote announce</b> parameter is:
+</p><pre class="programlisting">

+Use of WINS (either Samba WINS _or_ MS Windows NT Server WINS) is highly
+recommended. Every NetBIOS machine registers it's name together with a
+name_type value for each of of several types of service it has available.
+eg: It registers it's name directly as a unique (the type 0x03) name.
+It also registers it's name if it is running the lanmanager compatible
+server service (used to make shares and printers available to other users)
+by registering the server (the type 0x20) name.
+</p><p>
+All NetBIOS names are up to 15 characters in length. The name_type variable
+is added to the end of the name - thus creating a 16 character name. Any
+name that is shorter than 15 characters is padded with spaces to the 15th
+character. ie: All NetBIOS names are 16 characters long (including the
+name_type information).
+</p><p>
+WINS can store these 16 character names as they get registered. A client
+that wants to log onto the network can ask the WINS server for a list
+of all names that have registered the NetLogon service name_type. This saves
+broadcast traffic and greatly expedites logon processing. Since broadcast
+name resolution can not be used across network segments this type of
+information can only be provided via WINS _or_ via statically configured
+<tt>lmhosts</tt> files that must reside on all clients in the
+absence of WINS.
+</p><p>
+WINS also serves the purpose of forcing browse list synchronisation by all
+LMB's. LMB's must synchronise their browse list with the DMB (domain master
+browser) and WINS helps the LMB to identify it's DMB. By definition this
+will work only within a single workgroup. Note that the domain master browser
+has NOTHING to do with what is referred to as an MS Windows NT Domain. The
+later is a reference to a security environment while the DMB refers to the
+master controller for browse list information only.
+</p><p>
+Use of WINS will work correctly only if EVERY client TCP/IP protocol stack
+has been configured to use the WINS server/s. Any client that has not been
+configured to use the WINS server will continue to use only broadcast based
+name registration so that WINS may NEVER get to know about it. In any case,
+machines that have not registered with a WINS server will fail name to address
+lookup attempts by other clients and will therefore cause workstation access
+errors.
+</p><p>
+To configure Samba as a WINS server just add
+<b>wins support = yes</b> to the <tt>smb.conf</tt>
+file [globals] section.

+Either a Samba machine or a Windows NT Server machine may be set up
+as a WINS server. To set a Samba machine to be a WINS server you must
+add the following option to the <tt>smb.conf</tt> file on the selected machine :
+in the [globals] section add the line
+</p><p>
+</p><pre class="programlisting">
+ wins support = yes
+</pre><p>
+</p><p>
+Versions of Samba prior to 1.9.17 had this parameter default to
+yes. If you have any older versions of Samba on your network it is
+strongly suggested you upgrade to a recent version, or at the very
+least set the parameter to 'no' on all these machines.
+</p><p>
+Machines with <b>wins support = yes</b> will keep a list of
+all NetBIOS names registered with them, acting as a DNS for NetBIOS names.
+</p><p>
+You should set up only ONE wins server. Do NOT set the
+<b>wins support = yes</b> option on more than one Samba
+server.
+</p><p>
+To set up a Windows NT Server as a WINS server you need to set up
+the WINS service - see your NT documentation for details. Note that
+Windows NT WINS Servers can replicate to each other, allowing more
+than one to be set up in a complex subnet environment. As Microsoft
+refuse to document these replication protocols Samba cannot currently
+participate in these replications. It is possible in the future that
+a Samba-&gt;Samba WINS replication protocol may be defined, in which
+case more than one Samba machine could be set up as a WINS server
+but currently only one Samba server should have the
+<b>wins support = yes</b> parameter set.
+</p><p>
+After the WINS server has been configured you must ensure that all
+machines participating on the network are configured with the address
+of this WINS server. If your WINS server is a Samba machine, fill in
+the Samba machine IP address in the &quot;Primary WINS Server&quot; field of
+the &quot;Control Panel-&gt;Network-&gt;Protocols-&gt;TCP-&gt;WINS Server&quot; dialogs
+in Windows 95 or Windows NT. To tell a Samba server the IP address
+of the WINS server add the following line to the [global] section of
+all <tt>smb.conf</tt> files :
+</p><p>
+</p><pre class="programlisting">
+ wins server = &lt;name or IP address&gt;
+</pre><p>
+</p><p>
+where &lt;name or IP address&gt; is either the DNS name of the WINS server
+machine or its IP address.
+</p><p>
+Note that this line MUST NOT BE SET in the <tt>smb.conf</tt> file of the Samba
+server acting as the WINS server itself. If you set both the
+<b>wins support = yes</b> option and the
+<b>wins server = &lt;name&gt;</b> option then
+nmbd will fail to start.
+</p><p>
+There are two possible scenarios for setting up cross subnet browsing.

+Do NOT use more than one (1) protocol on MS Windows machines
+</p></div><p>
+A very common cause of browsing problems results from installing more than

+</p><p>
+Every NetBIOS machine takes part in a process of electing the LMB (and DMB)
+every 15 minutes. A set of election criteria is used to determine the order
+of precidence for winning this election process. A machine running Samba or
+Windows NT will be biased so that the most suitable machine will predictably
+win and thus retain it's role.
+</p><p>
+The election process is &quot;fought out&quot; so to speak over every NetBIOS network
+interface. In the case of a Windows 9x machine that has both TCP/IP and IPX
+installed and has NetBIOS enabled over both protocols the election will be
+decided over both protocols. As often happens, if the Windows 9x machine is
+the only one with both protocols then the LMB may be won on the NetBIOS
+interface over the IPX protocol. Samba will then lose the LMB role as Windows
+9x will insist it knows who the LMB is. Samba will then cease to function
+as an LMB and thus browse list operation on all TCP/IP only machines will
+fail.
+</p><p><span class="emphasis"><em>
+Windows 95, 98, 98se, Me are referred to generically as Windows 9x.

+XP/2003 introduce new protocol extensions that cause them to behave
+differently from MS Windows NT4. Generally, where a server does NOT support
+the newer or extended protocol, these will fall back to the NT4 protocols.
+</em></span></p><p>

+Many sites want to restrict DNS lookups and want to avoid broadcast name

+SMB networking provides a mechanism by which clients can access a list
+of machines in a network, a so-called <b>browse list</b>. This list
+contains machines that are ready to offer file and/or print services
+to other machines within the network. Thus it does not include
+machines which aren't currently able to do server tasks. The browse
+list is heavily used by all SMB clients. Configuration of SMB
+browsing has been problematic for some Samba users, hence this
+document.
+</p><p>
+MS Windows 2000 and later, as with Samba 3 and later, can be
+configured to not use NetBIOS over TCP/IP. When configured this way
+it is imperative that name resolution (using DNS/LDAP/ADS) be correctly
+configured and operative. Browsing will NOT work if name resolution
+from SMB machine names to IP addresses does not function correctly.
+</p><p>
+Where NetBIOS over TCP/IP is enabled use of a WINS server is highly
+recommended to aid the resolution of NetBIOS (SMB) names to IP addresses.
+WINS allows remote segment clients to obtain NetBIOS name_type information
+that can NOT be provided by any other means of name resolution.
+</p><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2865517"></a>Browsing support in samba</h3></div></div><p>
+Samba facilitates browsing. The browsing is supported by nmbd
+and is also controlled by options in the <tt>smb.conf</tt> file.
+Samba can act as a local browse master for a workgroup and the ability
+to support domain logons and scripts is now available.
+</p><p>
+Samba can also act as a domain master browser for a workgroup. This
+means that it will collate lists from local browse masters into a
+wide area network server list. In order for browse clients to
+resolve the names they may find in this list, it is recommended that
+both samba and your clients use a WINS server.
+</p><p>
+Note that you should NOT set Samba to be the domain master for a
+workgroup that has the same name as an NT Domain: on each wide area
+network, you must only ever have one domain master browser per workgroup,
+regardless of whether it is NT, Samba or any other type of domain master
+that is providing this service.
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+Nmbd can be configured as a WINS server, but it is not
+necessary to specifically use samba as your WINS server. MS Windows
+NT4, Server or Advanced Server 2000 or 2003 can be configured as
+your WINS server. In a mixed NT/2000/2003 server and samba environment on
+a Wide Area Network, it is recommended that you use the Microsoft
+WINS server capabilities. In a samba-only environment, it is
+recommended that you use one and only one Samba server as your WINS server.
+</p></div><p>
+To get browsing to work you need to run nmbd as usual, but will need
+to use the <b>workgroup</b> option in <tt>smb.conf</tt>
+to control what workgroup Samba becomes a part of.
+</p><p>
+Samba also has a useful option for a Samba server to offer itself for
+browsing on another subnet. It is recommended that this option is only
+used for 'unusual' purposes: announcements over the internet, for
+example. See <b>remote announce</b> in the
+<tt>smb.conf</tt> man page.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2865624"></a>Problem resolution</h3></div></div><p>
+If something doesn't work then hopefully the log.nmb file will help
+you track down the problem. Try a debug level of 2 or 3 for finding
+problems. Also note that the current browse list usually gets stored
+in text form in a file called <tt>browse.dat</tt>.
+</p><p>
+Note that if it doesn't work for you, then you should still be able to
+type the server name as <tt>\\SERVER</tt> in filemanager then
+hit enter and filemanager should display the list of available shares.
+</p><p>
+Some people find browsing fails because they don't have the global
+<b>guest account</b> set to a valid account. Remember that the
+IPC$ connection that lists the shares is done as guest, and thus you must
+have a valid guest account.
+</p><p><span class="emphasis"><em>
+MS Windows 2000 and upwards (as with Samba) can be configured to disallow
+anonymous (ie: Guest account) access to the IPC$ share. In that case, the
+MS Windows 2000/XP/2003 machine acting as an SMB/CIFS client will use the
+name of the currently logged in user to query the IPC$ share. MS Windows
+9X clients are not able to do this and thus will NOT be able to browse
+server resources.
+</em></span></p><p>
+The other big problem people have is that their broadcast address,

+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2865703"></a>Browsing across subnets</h3></div></div><p>
+Since the release of Samba 1.9.17(alpha1) Samba has been
+updated to enable it to support the replication of browse lists
+across subnet boundaries. New code and options have been added to
+achieve this. This section describes how to set this feature up
+in different settings.
+</p><p>
+To see browse lists that span TCP/IP subnets (ie. networks separated
+by routers that don't pass broadcast traffic) you must set up at least
+one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing
+NetBIOS name to IP address translation to be done by doing a direct
+query of the WINS server. This is done via a directed UDP packet on
+port 137 to the WINS server machine. The reason for a WINS server is
+that by default, all NetBIOS name to IP address translation is done
+by broadcasts from the querying machine. This means that machines
+on one subnet will not be able to resolve the names of machines on
+another subnet without using a WINS server.
+</p><p>
+Remember, for browsing across subnets to work correctly, all machines,
+be they Windows 95, Windows NT, or Samba servers must have the IP address
+of a WINS server given to them by a DHCP server, or by manual configuration
+(for Win95 and WinNT, this is in the TCP/IP Properties, under Network
+settings) for Samba this is in the <tt>smb.conf</tt> file.
+</p><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2865754"></a>How does cross subnet browsing work ?</h4></div></div><p>
+Cross subnet browsing is a complicated dance, containing multiple
+moving parts. It has taken Microsoft several years to get the code
+that achieves this correct, and Samba lags behind in some areas.
+Samba is capable of cross subnet browsing when configured correctly.
+</p><p>
+Consider a network set up as follows :
+</p><p>
+</p><pre class="programlisting">
+ (DMB)
+ N1_A N1_B N1_C N1_D N1_E
+ | | | | |
+ -------------------------------------------------------

+ -------------------------- ------------------------------------
+ | | | | | | | |
+ N2_A N2_B N2_C N2_D N3_A N3_B N3_C N3_D
+ (WINS)
+</pre><p>
+</p><p>
+Consisting of 3 subnets (1, 2, 3) connected by two routers
+(R1, R2) - these do not pass broadcasts. Subnet 1 has 5 machines
+on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume
+for the moment that all these machines are configured to be in the
+same workgroup (for simplicities sake). Machine N1_C on subnet 1
+is configured as Domain Master Browser (ie. it will collate the
+browse lists for the workgroup). Machine N2_D is configured as
+WINS server and all the other machines are configured to register
+their NetBIOS names with it.
+</p><p>
+As all these machines are booted up, elections for master browsers
+will take place on each of the three subnets. Assume that machine
+N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on
+subnet 3 - these machines are known as local master browsers for
+their particular subnet. N1_C has an advantage in winning as the
+local master browser on subnet 1 as it is set up as Domain Master
+Browser.
+</p><p>
+On each of the three networks, machines that are configured to
+offer sharing services will broadcast that they are offering
+these services. The local master browser on each subnet will
+receive these broadcasts and keep a record of the fact that
+the machine is offering a service. This list of records is
+the basis of the browse list. For this case, assume that
+all the machines are configured to offer services so all machines
+will be on the browse list.
+</p><p>
+For each network, the local master browser on that network is
+considered 'authoritative' for all the names it receives via
+local broadcast. This is because a machine seen by the local
+master browser via a local broadcast must be on the same
+network as the local master browser and thus is a 'trusted'
+and 'verifiable' resource. Machines on other networks that
+the local master browsers learn about when collating their
+browse lists have not been directly seen - these records are
+called 'non-authoritative'.
+</p><p>
+At this point the browse lists look as follows (these are
+the machines you would see in your network neighborhood if
+you looked in it on a particular network right now).
+</p><p>
+</p><pre class="programlisting">

+Subnet3 N3_D N3_A, N3_B, N3_C, N3_D
+</pre><p>
+</p><p>
+Note that at this point all the subnets are separate, no
+machine is seen across any of the subnets.
+</p><p>
+Now examine subnet 2. As soon as N2_B has become the local
+master browser it looks for a Domain master browser to synchronize
+its browse list with. It does this by querying the WINS server
+(N2_D) for the IP address associated with the NetBIOS name
+WORKGROUP&lt;1B&gt;. This name was registerd by the Domain master
+browser (N1_C) with the WINS server as soon as it was booted.
+</p><p>
+Once N2_B knows the address of the Domain master browser it
+tells it that is the local master browser for subnet 2 by
+sending a MasterAnnouncement packet as a UDP port 138 packet.
+It then synchronizes with it by doing a NetServerEnum2 call. This
+tells the Domain Master Browser to send it all the server
+names it knows about. Once the domain master browser receives
+the MasterAnnouncement packet it schedules a synchronization
+request to the sender of that packet. After both synchronizations
+are done the browse lists look like :

+ logging in. This is bad. The SMB encryption scheme never sends the
+ cleartext password over the network but it does store the 16 byte
+ hashed values on disk. This is also bad. Why? Because the 16 byte hashed
+ values are a &quot;password equivalent&quot;. You cannot derive the user's
+ password from them, but they could potentially be used in a modified
+ client to gain access to a server. This would require considerable
+ technical knowledge on behalf of the attacker but is perfectly possible.
+ You should thus treat the data stored in whatever
+ passdb backend you use (smbpasswd file, ldap, mysql) as though it contained the
+ cleartext passwords of all your users. Its contents must be kept
+ secret, and the file should be protected accordingly.</p><p>Ideally we would like a password scheme which neither requires
+ plain text passwords on the net or on disk. Unfortunately this
+ is not available as Samba is stuck with being compatible with
+ other SMB systems (WinNT, WfWg, Win95 etc). </p><div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3><p>Note that Windows NT 4.0 Service pack 3 changed the

+Traditionally, when configuring <a href="smb.conf.5.html#ENCRYPTPASSWORDS" target="_top">&quot;encrypt
+passwords = yes&quot;</a> in Samba's <tt>smb.conf</tt> file, user account
+information such as username, LM/NT password hashes, password change times, and account
+flags have been stored in the <tt>smbpasswd(5)</tt> file. There are several
+disadvantages to this approach for sites with very large numbers of users (counted
+in the thousands).
+</p><div class="itemizedlist"><ul type="disc"><li><p>
+The first is that all lookups must be performed sequentially. Given that
+there are approximately two lookups per domain logon (one for a normal
+session connection such as when mapping a network drive or printer), this
+is a performance bottleneck for large sites. What is needed is an indexed approach
+such as is used in databases.
+</p></li><li><p>
+The second problem is that administrators who desired to replicate a
+smbpasswd file to more than one Samba server were left to use external
+tools such as <b>rsync(1)</b> and <b>ssh(1)</b>
+and wrote custom, in-house scripts.
+</p></li><li><p>
+And finally, the amount of information which is stored in an
+smbpasswd entry leaves no room for additional attributes such as
+a home directory, password expiration time, or even a Relative
+Identified (RID).
+</p></li></ul></div><p>
+As a result of these defeciencies, a more robust means of storing user attributes
+used by smbd was developed. The API which defines access to user accounts
+is commonly referred to as the samdb interface (previously this was called the passdb
+API, and is still so named in the CVS trees).
+</p><p>
+There are a few points to stress about that the ldapsam
+does not provide. The LDAP support referred to in the this documentation does not
+include:
+</p><div class="itemizedlist"><ul type="disc"><li><p>A means of retrieving user account information from
+ an Windows 2000 Active Directory server.</p></li><li><p>A means of replacing /etc/passwd.</p></li></ul></div><p>
+The second item can be accomplished by using LDAP NSS and PAM modules. LGPL
+versions of these libraries can be obtained from PADL Software
+(<a href="http://www.padl.com/" target="_top">http://www.padl.com/</a>). More
+information about the configuration of these packages may be found at &quot;LDAP,

+The LDAP samdb code in 2.2.3 (and later) has been developed and tested
+using the OpenLDAP 2.0 server and client libraries.
+The same code should be able to work with Netscape's Directory Server

+to be compile errors and bugs. These should not be hard to fix.

+Samba 3.0 includes the necessary schema file for OpenLDAP 2.0 in
+<tt>examples/LDAP/samba.schema</tt>. The sambaAccount objectclass is given here:
+</p><pre class="programlisting">

+The samba.schema file has been formatted for OpenLDAP 2.0. The OID's are

+submit the modified schema file as a patch to <a href="mailto:jerry@samba.org" target="_top">jerry@samba.org</a>
+</p><p>
+Just as the smbpasswd file is meant to store information which supplements a
+user's <tt>/etc/passwd</tt> entry, so is the sambaAccount object
+meant to supplement the UNIX user account information. A sambaAccount is a
+<tt>STRUCTURAL</tt> objectclass so it can be stored individually
+in the directory. However, there are several fields (e.g. uid) which overlap
+with the posixAccount objectclass outlined in RFC2307. This is by design.
+</p><p>
+In order to store all user account information (UNIX and Samba) in the directory,
+it is necessary to use the sambaAccount and posixAccount objectclasses in
+combination. However, smbd will still obtain the user's UNIX account
+information via the standard C library calls (e.g. getpwnam(), et. al.).
+This means that the Samba server must also have the LDAP NSS library installed
+and functioning correctly. This division of information makes it possible to
+store all Samba account information in LDAP, but still maintain UNIX account
+information in NIS while the network is transitioning to a full LDAP infrastructure.

+To remedy the first security issue, the &quot;ldap ssl&quot; smb.conf parameter defaults

+ where X is the letter of the drive to map. Refer to the &quot;logon drive&quot; parameter in the
+ smb.conf(5) man page for more information.</p></li><li><p><tt>scriptPath</tt>: The scriptPath property specifies the path of
+ the user's logon script, .CMD, .EXE, or .BAT file. The string can be null. The path
+ is relative to the netlogon share. Refer to the &quot;logon script&quot; parameter in the
+ smb.conf(5) man page for more information.</p></li><li><p><tt>profilePath</tt>: specifies a path to the user's profile.

+ the home directory for the user. The string can be null. If homeDrive is set and specifies
+ a drive letter, homeDirectory should be a UNC path. The path must be a network
+ UNC path of the form \\server\share\directory. This value can be a null string.

+The majority of these parameters are only used when Samba is acting as a PDC of
+a domain (refer to the <a href="Samba-PDC-HOWTO.html" target="_top">Samba-PDC-HOWTO</a> for details on

+These attributes are only stored with the sambaAccount entry if
+the values are non-default values. For example, assume TASHTEGO has now been
+configured as a PDC and that <b>logon home = \\%L\%u</b> was defined in
+its <tt>smb.conf</tt> file. When a user named &quot;becky&quot; logons to the domain,
+the <i><tt>logon home</tt></i> string is expanded to \\TASHTEGO\becky.
+If the smbHome attribute exists in the entry &quot;uid=becky,ou=people,dc=samba,dc=org&quot;,
+this value is used. However, if this attribute does not exist, then the value
+of the <i><tt>logon home</tt></i> parameter is used in its place. Samba
+will only write the attribute value to the directory entry if the value is
+something other than the default (e.g. \\MOBY\becky).

When installing NT/W2K on a computer, the installer program creates some users
and groups. Notably the 'Administrators' group, and gives to that group some
privileges like the ability to change the date and time or to kill any process
(or close too) running on the local machine. The 'Administrator' user is a
member of the 'Administrators' group, and thus 'inherit' the 'Administrators'
group privileges. If a 'joe' user is created and become a member of the
-'Administrator' group, 'joe' has exactly the same rights as 'Administrator'.</P

+It is possible to map any arbitrary UNIX group to any Windows NT
+group as well as making any UNIX group a Windows domain group.
+For example, if you wanted to include a UNIX group (e.g. acct) in a ACL on a
+local file or printer on a domain member machine, you would flag
+that group as a domain group by running the following on the Samba PDC:
+</p><p><tt>root# </tt><b><tt>net groupmap add rid=1000 ntgroup=&quot;Accounting&quot; unixgroup=acct</tt></b></p><p>Be aware that the rid parmeter is a unsigned 32 bit integer that should
+normally start at 1000. However, this rid must not overlap with any RID assigned
+to a user. Verifying this is done differently depending on on the passdb backend
+you are using. Future versions of the tools may perform the verification automatically,
+but for now the burden in on you.</p><p>You can list the various groups in the mapping database by executing
+<b>net groupmap list</b>. Here is an example:</p><pre class="programlisting"><tt>root# </tt>net groupmap list

+The Common Unix Print System (CUPS) has become very popular, but to many it is
a very mystical tool. There is a great deal of uncertainty regarding CUPS and how
it works. The result is seen in a large number of posting on the samba mailing lists
expressing frustration when MS Windows printers appear not to work with a CUPS
-backr-end.</P
-><P
->This is a good time to point out how CUPS can be used and what it does. CUPS is more

+</p><p>
+This is a good time to point out how CUPS can be used and what it does. CUPS is more
than just a print spooling system - it is a complete printer management system that
complies with HTTP and IPP protocols. It can be managed remotely via a web browser
-and it can print using http and ipp protocols.</P
-><P
->CUPS allows to creation of RAW printers (ie: NO file format translation) as well as
+and it can print using http and ipp protocols.
+</p><p>
+CUPS allows to creation of RAW printers (ie: NO file format translation) as well as
SMART printers (ie: CUPS does file format conversion as required for the printer). In
many ways this gives CUPS similar capabilities to the MS Windows print monitoring
system. Of course, if you are a CUPS advocate, you would agrue that CUPS is better!
In any case, let us now move on to explore how one may configure CUPS for interfacing
-with MS Windows print clients via Samba.</P

have individual directories for the domain users already present on

can be set on MS Windows NT4/200x/XP shares. This can be a very effective way to limit who can
connect to a share. In the absence of specific restrictions the default setting is to allow

+Remember: NT4 policy files are named <tt>NTConfig.POL</tt> and are stored in the root
of the NETLOGON share on the domain controllers. A Windows NT4 user enters a username, a password
and selects the domain name to which the logon will attempt to take place. During the logon
process the client machine reads the NTConfig.POL file from the NETLOGON share on the authenticating
-server, modifies the local registry values according to the settings in this file.</P

in a shared (and replicated) volume called the SYSVOL folder. This folder is present on all Active
Directory domain controllers. The part that is stored in the Active Directory itself is called the

+With NT4 clients the policy file is read and executed upon only as each user logs onto the network.
MS Windows 200x policies are much more complex - GPOs are processed and applied at client machine
startup (machine specific part) and when the user logs onto the network the user specific part
is applied. In MS Windows 200x style policy management each machine and/or user may be subject
to any number of concurently applicable (and applied) policy sets (GPOs). Active Directory allows
the administrator to also set filters over the policy settings. No such equivalent capability

well beyond the scope of this documentation to explain how to program .adm files, for that

+Sharing of desktop profiles between Windows versions is NOT recommended.
Desktop profiles are an evolving phenomenon and profiles for later versions
of MS Windows clients add features that may interfere with earlier versions
of MS Windows clients. Probably the more salient reason to NOT mix profiles
is that when logging off an earlier version of MS Windows the older format
of profile contents may overwrite information that belongs to the newer
version resulting in loss of profile information content when that user logs

+MS Windows NT3.x/4.0 type security domains employ a non-hierarchical security structure.
The limitations of this architecture as it affects the scalability of MS Windows networking
in large organisations is well known. Additionally, the flat-name space that results from
this design significantly impacts the delegation of administrative responsibilities in

+</p><p>
+Microsoft developed Active Directory Service (ADS), based on Kerberos and LDAP, as a means
of circumventing the limitations of the older technologies. Not every organisation is ready
or willing to embrace ADS. For small companies the older NT4 style domain security paradigm
is quite adequate, there thus remains an entrenched user base for whom there is no direct
-desire to go through a disruptive change to adopt ADS.</P

+desire to go through a disruptive change to adopt ADS.
+</p><p>
+Microsoft introduced with MS Windows NT the ability to allow differing security domains
to affect a mechanism so that users from one domain may be given access rights and privileges
in another domain. The language that describes this capability is couched in terms of
-<SPAN

-> the users
+<span class="emphasis"><em>Trusts</em></span>. Specifically, one domain will <span class="emphasis"><em>trust</em></span> the users
from another domain. The domain from which users are available to another security domain is
said to be a trusted domain. The domain in which those users have assigned rights and privileges
is the trusting domain. With NT3.x/4.0 all trust relationships are always in one direction only,
thus if users in both domains are to have privileges and rights in each others' domain, then it is
-necessary to establish two (2) relationships, one in each direction.</P

+</p><p>
+In an NT4 style MS security domain, all trusts are non-transitive. This means that if there
are three (3) domains (let's call them RED, WHITE, and BLUE) where RED and WHITE have a trust
relationship, and WHITE and BLUE have a trust relationship, then it holds that there is no
implied trust between the RED and BLUE domains. ie: Relationships are explicit and not
-transitive.</P
-><P
->New to MS Windows 2000 ADS security contexts is the fact that trust relationships are two-way

+</p><p>
+New to MS Windows 2000 ADS security contexts is the fact that trust relationships are two-way
by default. Also, all inter-ADS domain trusts are transitive. In the case of the RED, WHITE and BLUE
domains above, with Windows 2000 and ADS the RED and BLUE domains CAN trust each other. This is
an inherent feature of ADS domains. Samba-3 implements MS Windows NT4
style Interdomain trusts and interoperates with MS Windows 200x ADS

+pam_smbpass is a PAM module which can be used on conforming systems to
+keep the smbpasswd (Samba password) database in sync with the unix
+password file. PAM (Pluggable Authentication Modules) is an API supported
+under some Unices, such as Solaris, HPUX and Linux, that provides a
+generic interface to authentication mechanisms.
+</p><p>
+For more information on PAM, see http://ftp.kernel.org/pub/linux/libs/pam/
+</p><p>
+This module authenticates a local smbpasswd user database. If you require
+support for authenticating against a remote SMB server, or if you're
+concerned about the presence of suid root binaries on your system, it is
+recommended that you use pam_winbind instead.
+</p><pre class="programlisting">
+Options recognized by this module are as follows:
+
+ debug - log more debugging info
+ audit - like debug, but also logs unknown usernames
+ use_first_pass - don't prompt the user for passwords;
+ take them from PAM_ items instead
+ try_first_pass - try to get the password from a previous
+ PAM module, fall back to prompting the user
+ use_authtok - like try_first_pass, but *fail* if the new
+ PAM_AUTHTOK has not been previously set.
+ (intended for stacking password modules only)
+ not_set_pass - don't make passwords used by this module
+ available to other modules.
+ nodelay - don't insert ~1 second delays on authentication
+ failure.
+ nullok - null passwords are allowed.
+ nonull - null passwords are not allowed. Used to
+ override the Samba configuration.
+ migrate - only meaningful in an &quot;auth&quot; context;
+ used to update smbpasswd file with a
+ password used for successful authentication.
+ smbconf=&lt; file &gt; - specify an alternate path to the smb.conf
+ file.

+I have created a VFS module which implements a fairly complete read-only
filesystem. It presents information from a database as a filesystem in
a modular and generic way to allow different databases to be used
(originally designed for organizing MP3s under directories such as
-"Artists," "Song Keywords," etc... I have since applied it to a student
+&quot;Artists,&quot; &quot;Song Keywords,&quot; etc... I have since applied it to a student
roster database very easily). The directory structure is stored in the
database itself and the module makes no assumptions about the database
-structure beyond the table it requires to run.</P

+One area which sometimes causes trouble is locking.
+</p><p>
+There are two types of locking which need to be performed by a SMB server.
+The first is <span class="emphasis"><em>record locking</em></span> which allows a client to lock
+a range of bytes in a open file. The second is the <span class="emphasis"><em>deny modes</em></span>
+that are specified when a file is open.
+</p><p>
+Record locking semantics under Unix is very different from record locking under
+Windows. Versions of Samba before 2.2 have tried to use the native fcntl() unix
+system call to implement proper record locking between different Samba clients.
+This can not be fully correct due to several reasons. The simplest is the fact
+that a Windows client is allowed to lock a byte range up to 2^32 or 2^64,
+depending on the client OS. The unix locking only supports byte ranges up to 2^31.
+So it is not possible to correctly satisfy a lock request above 2^31. There are
+many more differences, too many to be listed here.
+</p><p>
+Samba 2.2 and above implements record locking completely independent of the
+underlying unix system. If a byte range lock that the client requests happens
+to fall into the range 0-2^31, Samba hands this request down to the Unix system.
+All other locks can not be seen by unix anyway.
+</p><p>
+Strictly a SMB server should check for locks before every read and write call on
+a file. Unfortunately with the way fcntl() works this can be slow and may overstress
+the rpc.lockd. It is also almost always unnecessary as clients are supposed to
+independently make locking calls before reads and writes anyway if locking is
+important to them. By default Samba only makes locking calls when explicitly asked
+to by a client, but if you set <span class="emphasis"><em>strict locking = yes</em></span> then it
+will make lock checking calls on every read and write.
+</p><p>
+You can also disable by range locking completely using <span class="emphasis"><em>locking = no</em></span>.
+This is useful for those shares that don't support locking or don't need it
+(such as cdroms). In this case Samba fakes the return codes of locking calls to
+tell clients that everything is OK.
+</p><p>
+The second class of locking is the <span class="emphasis"><em>deny modes</em></span>. These
+are set by an application when it opens a file to determine what types of
+access should be allowed simultaneously with its open. A client may ask for
+DENY_NONE, DENY_READ, DENY_WRITE or DENY_ALL. There are also special compatibility
+modes called DENY_FCB and DENY_DOS.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2884872"></a>Samba Opportunistic Locking Control</h2></div></div><p>
+Opportunistic locking essentially means that the client is allowed to download and cache
+a file on their hard drive while making changes; if a second client wants to access the
+file, the first client receives a break and must synchronise the file back to the server.
+This can give significant performance gains in some cases; some programs insist on
+synchronising the contents of the entire file back to the server for a single change.
+</p><p>
+Level1 Oplocks (aka just plain &quot;oplocks&quot;) is another term for opportunistic locking.
+</p><p>
+Level2 Oplocks provids opportunistic locking for a file that will be treated as
+<span class="emphasis"><em>read only</em></span>. Typically this is used on files that are read-only or
+on files that the client has no initial intention to write to at time of opening the file.
+</p><p>
+Kernel Oplocks are essentially a method that allows the Linux kernel to co-exist with
+Samba's oplocked files, although this has provided better integration of MS Windows network
+file locking with the under lying OS, SGI IRIX and Linux are the only two OS's that are
+oplock aware at this time.
+</p><p>
+Unless your system supports kernel oplocks, you should disable oplocks if you are
+accessing the same files from both Unix/Linux and SMB clients. Regardless, oplocks should
+always be disabled if you are sharing a database file (e.g., Microsoft Access) between
+multiple clients, as any break the first client receives will affect synchronisation of
+the entire file (not just the single record), which will result in a noticable performance
+impairment and, more likely, problems accessing the database in the first place. Notably,
+Microsoft Outlook's personal folders (*.pst) react very badly to oplocks. If in doubt,
+disable oplocks and tune your system from that point.
+</p><p>
+If client-side caching is desirable and reliable on your network, you will benefit from
+turning on oplocks. If your network is slow and/or unreliable, or you are sharing your
+files among other file sharing mechanisms (e.g., NFS) or across a WAN, or multiple people
+will be accessing the same files frequently, you probably will not benefit from the overhead
+of your client sending oplock breaks and will instead want to disable oplocks for the share.
+</p><p>
+Another factor to consider is the perceived performance of file access. If oplocks provide no
+measurable speed benefit on your network, it might not be worth the hassle of dealing with them.
+</p><p>
+You can disable oplocks on a per-share basis with the following:
+
+</p><pre class="programlisting">
+ oplocks = False
+ level2 oplocks = False
+</pre><p>
+
+Alternately, you could disable oplocks on a per-file basis within the share:
+
+</p><pre class="programlisting">
+ veto oplock files = /*.mdb/*.MDB/*.dbf/*.DBF/
+</pre><p>
+</p><p>
+If you are experiencing problems with oplocks as apparent from Samba's log entries,
+you may want to play it safe and disable oplocks and level2 oplocks.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2884987"></a>MS Windows Opportunistic Locking and Caching Controls</h2></div></div><p>
+There is a known issue when running applications (like Norton Anti-Virus) on a Windows 2000/ XP
+workstation computer that can affect any application attempting to access shared database files
+across a network. This is a result of a default setting configured in the Windows 2000/XP
+operating system known as <span class="emphasis"><em>Opportunistic Locking</em></span>. When a workstation
+attempts to access shared data files located on another Windows 2000/XP computer,
+the Windows 2000/XP operating system will attempt to increase performance by locking the
+files and caching information locally. When this occurs, the application is unable to
+properly function, which results in an <span class="emphasis"><em>Access Denied</em></span>
+ error message being displayed during network operations.
+</p><p>
+All Windows operating systems in the NT family that act as database servers for data files
+(meaning that data files are stored there and accessed by other Windows PCs) may need to
+have opportunistic locking disabled in order to minimize the risk of data file corruption.
+This includes Windows 9x/Me, Windows NT, Windows 200x and Windows XP.
+</p><p>
+If you are using a Windows NT family workstation in place of a server, you must also
+disable opportunistic locking (oplocks) on that workstation. For example, if you use a
+PC with the Windows NT Workstation operating system instead of Windows NT Server, and you
+have data files located on it that are accessed from other Windows PCs, you may need to
+disable oplocks on that system.
+</p><p>
+The major difference is the location in the Windows registry where the values for disabling
+oplocks are entered. Instead of the LanManServer location, the LanManWorkstation location
+may be used.
+</p><p>
+You can verify (or change or add, if necessary) this Registry value using the Windows
+Registry Editor. When you change this registry value, you will have to reboot the PC
+to ensure that the new setting goes into effect.
+</p><p>
+The location of the client registry entry for opportunistic locking has changed in
+Windows 2000 from the earlier location in Microsoft Windows NT.
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+Windows 2000 will still respect the EnableOplocks registry value used to disable oplocks
+in earlier versions of Windows.
+</p></div><p>
+You can also deny the granting of opportunistic locks by changing the following registry entries:
+</p><p>
+</p><pre class="programlisting">
+ HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\
+
+ OplocksDisabled REG_DWORD 0 or 1
+ Default: 0 (not disabled)
+</pre><p>

+This file contains a list of tests you can perform to validate your
+Samba server. It also tells you what the likely cause of the problem
+is if it fails any one of these steps. If it passes all these tests
+then it is probably working fine.
+</p><p>
+You should do ALL the tests, in the order shown. We have tried to
+carefully choose them so later tests only use capabilities verified in
+the earlier tests. However, do not stop at the first error as there
+have been some instances when continuing with the tests has helped
+to solve a problem.
+</p><p>
+If you send one of the samba mailing lists an email saying &quot;it doesn't work&quot;
+and you have not followed this test procedure then you should not be surprised
+if your email is ignored.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2884810"></a>Assumptions</h2></div></div><p>
+In all of the tests it is assumed you have a Samba server called
+BIGSERVER and a PC called ACLIENT both in workgroup TESTGROUP.
+</p><p>
+The procedure is similar for other types of clients.
+</p><p>
+It is also assumed you know the name of an available share in your
+<tt>smb.conf</tt>. I will assume this share is called <i><tt>tmp</tt></i>.
+You can add a <i><tt>tmp</tt></i> share like this by adding the
+following to <tt>smb.conf</tt>:
+</p><pre class="programlisting">
+
+[tmp]
+ comment = temporary files
+ path = /tmp
+ read only = yes
+
+</pre><p>
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+These tests assume version 3.0 or later of the samba suite.
+Some commands shown did not exist in earlier versions.
+</p></div><p>
+Please pay attention to the error messages you receive. If any error message
+reports that your server is being unfriendly you should first check that your
+IP name resolution is correctly set up. eg: Make sure your <tt>/etc/resolv.conf</tt>
+file points to name servers that really do exist.
+</p><p>
+Also, if you do not have DNS server access for name resolution please check
+that the settings for your <tt>smb.conf</tt> file results in <b>dns proxy = no</b>. The
+best way to check this is with <b><tt>testparm smb.conf</tt></b>.
+</p><p>
+It is helpful to monitor the log files during testing by using the
+<b>tail -F <i><tt>log_file_name</tt></i></b> in a separate
+terminal console (use ctrl-alt-F1 through F6 or multiple terminals in X).
+Relevant log files can be found (for default installations) in
+<tt>/usr/local/samba/var</tt>. Also, connection logs from
+machines can be found here or possibly in <tt>/var/log/samba</tt>
+depending on how or if you specified logging in your <tt>smb.conf</tt> file.
+</p><p>
+If you make changes to your <tt>smb.conf</tt> file while going through these test,
+don't forget to restart smbd and nmbd.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2793401"></a>The tests</h2></div></div><div class="procedure"><p class="title"><b>Procedure 27.1. Diagnosing your samba server</b></p><ol type="1"><li><p>
+In the directory in which you store your <tt>smb.conf</tt> file, run the command
+<b><tt>testparm smb.conf</tt></b>. If it reports any errors then your <tt>smb.conf</tt>
+configuration file is faulty.
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+Your <tt>smb.conf</tt> file may be located in: <tt>/etc/samba</tt>
+Or in: <tt>/usr/local/samba/lib</tt>
+</p></div></li><li><p>
+Run the command <b><tt>ping BIGSERVER</tt></b> from the PC and
+<b><tt>ping ACLIENT</tt></b> from
+the unix box. If you don't get a valid response then your TCP/IP
+software is not correctly installed.
+</p><p>
+Note that you will need to start a &quot;dos prompt&quot; window on the PC to
+run ping.
+</p><p>
+If you get a message saying &quot;host not found&quot; or similar then your DNS
+software or <tt>/etc/hosts</tt> file is not correctly setup.
+It is possible to
+run samba without DNS entries for the server and client, but I assume
+you do have correct entries for the remainder of these tests.
+</p><p>
+Another reason why ping might fail is if your host is running firewall
+software. You will need to relax the rules to let in the workstation
+in question, perhaps by allowing access from another subnet (on Linux
+this is done via the ipfwadm program.)
+</p><p>
+Note: Modern Linux distributions install ipchains/iptables by default.
+This is a common problem that is often overlooked.
+</p></li><li><p>
+Run the command <b><tt>smbclient -L BIGSERVER</tt></b> on the unix box. You
+should get a list of available shares back.
+</p><p>
+If you get a error message containing the string &quot;Bad password&quot; then
+you probably have either an incorrect <b>hosts allow</b>,
+<b>hosts deny</b> or <b>valid users</b> line in your
+<tt>smb.conf</tt>, or your guest account is not
+valid. Check what your guest account is using testparm and
+temporarily remove any <b>hosts allow</b>, <b>hosts deny</b>, <b>valid users</b> or <b>invalid users</b> lines.
+</p><p>
+If you get a &quot;connection refused&quot; response then the smbd server may
+not be running. If you installed it in inetd.conf then you probably edited
+that file incorrectly. If you installed it as a daemon then check that
+it is running, and check that the netbios-ssn port is in a LISTEN
+state using <b><tt>netstat -a</tt></b>.
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+Some Unix / Linux systems use <b>xinetd</b> in place of
+<b>inetd</b>. Check your system documentation for the location
+of the control file/s for your particular system implementation of
+this network super daemon.
+</p></div><p>
+If you get a &quot;session request failed&quot; then the server refused the
+connection. If it says &quot;Your server software is being unfriendly&quot; then
+its probably because you have invalid command line parameters to smbd,
+or a similar fatal problem with the initial startup of smbd. Also
+check your config file (<tt>smb.conf</tt>) for syntax errors with testparm
+and that the various directories where samba keeps its log and lock
+files exist.
+</p><p>
+There are a number of reasons for which smbd may refuse or decline
+a session request. The most common of these involve one or more of
+the following <tt>smb.conf</tt> file entries:
+</p><pre class="programlisting">
+ hosts deny = ALL
+ hosts allow = xxx.xxx.xxx.xxx/yy
+ bind interfaces only = Yes
+</pre><p>
+In the above, no allowance has been made for any session requests that
+will automatically translate to the loopback adaptor address 127.0.0.1.
+To solve this problem change these lines to:
+</p><pre class="programlisting">
+ hosts deny = ALL
+ hosts allow = xxx.xxx.xxx.xxx/yy 127.
+</pre><p>
+Do NOT use the <b>bind interfaces only</b> parameter where you
+may wish to
+use the samba password change facility, or where smbclient may need to
+access a local service for name resolution or for local resource
+connections. (Note: the <b>bind interfaces only</b> parameter deficiency
+where it will not allow connections to the loopback address will be
+fixed soon).
+</p><p>
+Another common cause of these two errors is having something already running
+on port 139, such as Samba (ie: smbd is running from inetd already) or
+something like Digital's Pathworks. Check your <tt>inetd.conf</tt> file before trying
+to start smbd as a daemon, it can avoid a lot of frustration!
+</p><p>
+And yet another possible cause for failure of this test is when the subnet mask
+and / or broadcast address settings are incorrect. Please check that the
+network interface IP Address / Broadcast Address / Subnet Mask settings are
+correct and that Samba has correctly noted these in the <tt>log.nmb</tt> file.
+</p></li><li><p>
+Run the command <b><tt>nmblookup -B BIGSERVER __SAMBA__</tt></b>. You should get the
+IP address of your Samba server back.
+</p><p>
+If you don't then nmbd is incorrectly installed. Check your <tt>inetd.conf</tt>
+if you run it from there, or that the daemon is running and listening
+to udp port 137.
+</p><p>
+One common problem is that many inetd implementations can't take many
+parameters on the command line. If this is the case then create a
+one-line script that contains the right parameters and run that from
+inetd.
+</p></li><li><p>run the command <b><tt>nmblookup -B ACLIENT '*'</tt></b></p><p>
+You should get the PCs IP address back. If you don't then the client
+software on the PC isn't installed correctly, or isn't started, or you
+got the name of the PC wrong.
+</p><p>
+If ACLIENT doesn't resolve via DNS then use the IP address of the
+client in the above test.
+</p></li><li><p>
+Run the command <b><tt>nmblookup -d 2 '*'</tt></b>
+</p><p>
+This time we are trying the same as the previous test but are trying
+it via a broadcast to the default broadcast address. A number of
+Netbios/TCPIP hosts on the network should respond, although Samba may
+not catch all of the responses in the short time it listens. You
+should see &quot;got a positive name query response&quot; messages from several
+hosts.
+</p><p>
+If this doesn't give a similar result to the previous test then
+nmblookup isn't correctly getting your broadcast address through its
+automatic mechanism. In this case you should experiment with the
+<b>interfaces</b> option in <tt>smb.conf</tt> to manually configure your IP
+address, broadcast and netmask.
+</p><p>
+If your PC and server aren't on the same subnet then you will need to
+use the <i><tt>-B</tt></i> option to set the broadcast address to that of the PCs
+subnet.
+</p><p>
+This test will probably fail if your subnet mask and broadcast address are
+not correct. (Refer to TEST 3 notes above).
+</p></li><li><p>
+Run the command <b><tt>smbclient //BIGSERVER/TMP</tt></b>. You should
+then be prompted for a password. You should use the password of the account
+you are logged into the unix box with. If you want to test with
+another account then add the <i><tt>-U <i><tt>accountname</tt></i></tt></i> option to the end of
+the command line. eg:
+<b><tt>smbclient //bigserver/tmp -Ujohndoe</tt></b>
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+It is possible to specify the password along with the username
+as follows:
+<b><tt>smbclient //bigserver/tmp -Ujohndoe%secret</tt></b>
+</p></div><p>
+Once you enter the password you should get the <tt>smb&gt;</tt> prompt. If you
+don't then look at the error message. If it says &quot;invalid network
+name&quot; then the service &quot;tmp&quot; is not correctly setup in your <tt>smb.conf</tt>.
+</p><p>
+If it says &quot;bad password&quot; then the likely causes are:
+</p><div class="orderedlist"><ol type="1"><li><p>
+ you have shadow passords (or some other password system) but didn't
+ compile in support for them in smbd
+ </p></li><li><p>
+ your <b>valid users</b> configuration is incorrect
+ </p></li><li><p>
+ you have a mixed case password and you haven't enabled the <b>password
+ level</b> option at a high enough level
+ </p></li><li><p>
+ the <b>path =</b> line in <tt>smb.conf</tt> is incorrect. Check it with testparm
+ </p></li><li><p>
+ you enabled password encryption but didn't create the SMB encrypted
+ password file
+ </p></li></ol></div><p>
+Once connected you should be able to use the commands
+<b>dir</b> <b>get</b> <b>put</b> etc.
+Type <b>help <i><tt>command</tt></i></b> for instructions. You should
+especially check that the amount of free disk space shown is correct
+when you type <b>dir</b>.
+</p></li><li><p>
+On the PC, type the command <b><tt>net view \\BIGSERVER</tt></b>. You will
+need to do this from within a &quot;dos prompt&quot; window. You should get back a
+list of available shares on the server.
+</p><p>
+If you get a &quot;network name not found&quot; or similar error then netbios
+name resolution is not working. This is usually caused by a problem in
+nmbd. To overcome it you could do one of the following (you only need
+to choose one of them):
+</p><div class="orderedlist"><ol type="1"><li><p>
+ fixup the nmbd installation
+</p></li><li><p>
+ add the IP address of BIGSERVER to the <b>wins server</b> box in the
+ advanced tcp/ip setup on the PC.
+</p></li><li><p>
+ enable windows name resolution via DNS in the advanced section of
+ the tcp/ip setup
+</p></li><li><p>
+ add BIGSERVER to your lmhosts file on the PC.
+</p></li></ol></div><p>
+If you get a &quot;invalid network name&quot; or &quot;bad password error&quot; then the
+same fixes apply as they did for the <b><tt>smbclient -L</tt></b> test above. In
+particular, make sure your <b>hosts allow</b> line is correct (see the man
+pages)
+</p><p>
+Also, do not overlook that fact that when the workstation requests the
+connection to the samba server it will attempt to connect using the
+name with which you logged onto your Windows machine. You need to make
+sure that an account exists on your Samba server with that exact same
+name and password.
+</p><p>
+If you get &quot;specified computer is not receiving requests&quot; or similar
+it probably means that the host is not contactable via tcp services.
+Check to see if the host is running tcp wrappers, and if so add an entry in
+the <tt>hosts.allow</tt> file for your client (or subnet, etc.)
+</p></li><li><p>
+Run the command <b><tt>net use x: \\BIGSERVER\TMP</tt></b>. You should
+be prompted for a password then you should get a &quot;command completed
+successfully&quot; message. If not then your PC software is incorrectly
+installed or your smb.conf is incorrect. make sure your <b>hosts allow</b>
+and other config lines in <tt>smb.conf</tt> are correct.
+</p><p>
+It's also possible that the server can't work out what user name to
+connect you as. To see if this is the problem add the line <b>user =
+<i><tt>username</tt></i></b> to the <b>[tmp]</b> section of
+<tt>smb.conf</tt> where <i><tt>username</tt></i> is the
+username corresponding to the password you typed. If you find this
+fixes things you may need the username mapping option.
+</p><p>
+It might also be the case that your client only sends encrypted passwords
+and you have <b>encrypt passwords = no</b> in <tt>smb.conf</tt>
+Turn it back on to fix.
+</p></li><li><p>
+Run the command <b><tt>nmblookup -M <i><tt>testgroup</tt></i></tt></b> where
+<i><tt>testgroup</tt></i> is the name of the workgroup that your Samba server and
+Windows PCs belong to. You should get back the IP address of the
+master browser for that workgroup.
+</p><p>
+If you don't then the election process has failed. Wait a minute to
+see if it is just being slow then try again. If it still fails after
+that then look at the browsing options you have set in <tt>smb.conf</tt>. Make
+sure you have <b>preferred master = yes</b> to ensure that
+an election is held at startup.
+</p></li><li><p>
+&gt;From file manager try to browse the server. Your samba server should
+appear in the browse list of your local workgroup (or the one you
+specified in smb.conf). You should be able to double click on the name
+of the server and get a list of shares. If you get a &quot;invalid
+password&quot; error when you do then you are probably running WinNT and it
+is refusing to browse a server that has no encrypted password
+capability and is in user level security mode. In this case either set
+<b>security = server</b> AND
+<b>password server = Windows_NT_Machine</b> in your
+<tt>smb.conf</tt> file, or make sure <b>encrypted passwords</b> is
+set to &quot;yes&quot;.

+There are many sources of information available in the form
+of mailing lists, RFC's and documentation. The docs that come
+with the samba distribution contain very good explanations of
+general SMB topics such as browsing.</p><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2790687"></a>Diagnostics tools</h2></div></div><p>
+One of the best diagnostic tools for debugging problems is Samba itself.
+You can use the -d option for both smbd and nmbd to specify what
+'debug level' at which to run. See the man pages on smbd, nmbd and
+smb.conf for more information on debugging options. The debug
+level can range from 1 (the default) to 10 (100 for debugging passwords).
+</p><p>
+Another helpful method of debugging is to compile samba using the
+<b>gcc -g </b> flag. This will include debug
+information in the binaries and allow you to attach gdb to the
+running smbd / nmbd process. In order to attach gdb to an smbd
+process for an NT workstation, first get the workstation to make the
+connection. Pressing ctrl-alt-delete and going down to the domain box
+is sufficient (at least, on the first time you join the domain) to
+generate a 'LsaEnumTrustedDomains'. Thereafter, the workstation
+maintains an open connection, and therefore there will be an smbd
+process running (assuming that you haven't set a really short smbd
+idle timeout) So, in between pressing ctrl alt delete, and actually
+typing in your password, you can attach gdb and continue.
+</p><p>
+Some useful samba commands worth investigating:
+</p><div class="itemizedlist"><ul type="disc"><li><p>testparam | more</p></li><li><p>smbclient -L //{netbios name of server}</p></li></ul></div><p>
+An SMB enabled version of tcpdump is available from
+<a href="http://www.tcpdump.org/" target="_top">http://www.tcpdup.org/</a>.
+Ethereal, another good packet sniffer for Unix and Win32
+hosts, can be downloaded from <a href="http://www.ethereal.com/" target="_top">http://www.ethereal.com</a>.
+</p><p>
+For tracing things on the Microsoft Windows NT, Network Monitor
+(aka. netmon) is available on the Microsoft Developer Network CD's,
+the Windows NT Server install CD and the SMS CD's. The version of
+netmon that ships with SMS allows for dumping packets between any two
+computers (i.e. placing the network interface in promiscuous mode).
+The version on the NT Server install CD will only allow monitoring
+of network traffic directed to the local NT box and broadcasts on the
+local subnet. Be aware that Ethereal can read and write netmon
+formatted files.

+Installing netmon on an NT workstation requires a couple
+of steps. The following are for installing Netmon V4.00.349, which comes
+with Microsoft Windows NT Server 4.0, on Microsoft Windows NT
+Workstation 4.0. The process should be similar for other versions of
+Windows NT / Netmon. You will need both the Microsoft Windows
+NT Server 4.0 Install CD and the Workstation 4.0 Install CD.
+</p><p>
+Initially you will need to install 'Network Monitor Tools and Agent'
+on the NT Server. To do this
+</p><div class="itemizedlist"><ul type="disc"><li><p>Goto Start - Settings - Control Panel -
+ Network - Services - Add </p></li><li><p>Select the 'Network Monitor Tools and Agent' and
+ click on 'OK'.</p></li><li><p>Click 'OK' on the Network Control Panel.
+ </p></li><li><p>Insert the Windows NT Server 4.0 install CD
+ when prompted.</p></li></ul></div><p>
+At this point the Netmon files should exist in
+<tt>%SYSTEMROOT%\System32\netmon\*.*</tt>.
+Two subdirectories exist as well, <tt>parsers\</tt>
+which contains the necessary DLL's for parsing the netmon packet
+dump, and <tt>captures\</tt>.
+</p><p>
+In order to install the Netmon tools on an NT Workstation, you will
+first need to install the 'Network Monitor Agent' from the Workstation
+install CD.
+</p><div class="itemizedlist"><ul type="disc"><li><p>Goto Start - Settings - Control Panel -
+ Network - Services - Add</p></li><li><p>Select the 'Network Monitor Agent' and click
+ on 'OK'.</p></li><li><p>Click 'OK' on the Network Control Panel.
+ </p></li><li><p>Insert the Windows NT Workstation 4.0 install
+ CD when prompted.</p></li></ul></div><p>
+Now copy the files from the NT Server in %SYSTEMROOT%\System32\netmon\*.*
+to %SYSTEMROOT%\System32\netmon\*.* on the Workstation and set
+permissions as you deem appropriate for your site. You will need
+administrative rights on the NT box to run netmon.
+</p><p>
+To install Netmon on a Windows 9x box install the network monitor agent
+from the Windows 9x CD (\admin\nettools\netmon). There is a readme
+file located with the netmon driver files on the CD if you need
+information on how to do this. Copy the files from a working
+Netmon installation.

+Many people active on the lists subscribe to more

+Please take the time to read this file before you submit a bug
+report. Also, please see if it has changed between releases, as we
+may be changing the bug reporting mechanism at some time.
+</p><p>
+Please also do as much as you can yourself to help track down the
+bug. Samba is maintained by a dedicated group of people who volunteer
+their time, skills and efforts. We receive far more mail about it than
+we can possibly answer, so you have a much higher chance of an answer
+and a fix if you send us a &quot;developer friendly&quot; bug report that lets
+us fix it fast.
+</p><p>
+Do not assume that if you post the bug to the comp.protocols.smb
+newsgroup or the mailing list that we will read it. If you suspect that your
+problem is not a bug but a configuration problem then it is better to send
+it to the Samba mailing list, as there are (at last count) 5000 other users on
+that list that may be able to help you.
+</p><p>
+You may also like to look though the recent mailing list archives,
+which are conveniently accessible on the Samba web pages
+at <a href="http://samba.org/samba/" target="_top">http://samba.org/samba/</a>.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2886937"></a>General info</h2></div></div><p>
+Before submitting a bug report check your config for silly
+errors. Look in your log files for obvious messages that tell you that
+you've misconfigured something and run testparm to test your config
+file for correct syntax.
+</p><p>
+Have you run through the <a href="#diagnosis" title="Chapter 27. The samba checklist">diagnosis</a>?
+This is very important.
+</p><p>
+If you include part of a log file with your bug report then be sure to
+annotate it with exactly what you were doing on the client at the
+time, and exactly what the results were.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2887713"></a>Debug levels</h2></div></div><p>
+If the bug has anything to do with Samba behaving incorrectly as a
+server (like refusing to open a file) then the log files will probably
+be very useful. Depending on the problem a log level of between 3 and
+10 showing the problem may be appropriate. A higher level givesmore
+detail, but may use too much disk space.
+</p><p>
+To set the debug level use <b>log level =</b> in your
+<tt>smb.conf</tt>. You may also find it useful to set the log
+level higher for just one machine and keep separate logs for each machine.
+To do this use:
+</p><pre class="programlisting">
+log level = 10
+log file = /usr/local/samba/lib/log.%m
+include = /usr/local/samba/lib/smb.conf.%m
+</pre><p>
+then create a file
+<tt>/usr/local/samba/lib/smb.conf.<i><tt>machine</tt></i></tt> where
+<i><tt>machine</tt></i> is the name of the client you wish to debug. In that file
+put any <tt>smb.conf</tt> commands you want, for example
+<b>log level=</b> may be useful. This also allows you to
+experiment with different security systems, protocol levels etc on just
+one machine.
+</p><p>
+The <tt>smb.conf</tt> entry <b>log level =</b>
+is synonymous with the entry <b>debuglevel =</b> that has been
+used in older versions of Samba and is being retained for backwards
+compatibility of <tt>smb.conf</tt> files.
+</p><p>
+As the <b>log level =</b> value is increased you will record
+a significantly increasing level of debugging information. For most
+debugging operations you may not need a setting higher than 3. Nearly
+all bugs can be tracked at a setting of 10, but be prepared for a VERY
+large volume of log data.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2887849"></a>Internal errors</h2></div></div><p>
+If you get a &quot;INTERNAL ERROR&quot; message in your log files it means that
+Samba got an unexpected signal while running. It is probably a
+segmentation fault and almost certainly means a bug in Samba (unless
+you have faulty hardware or system software).
+</p><p>
+If the message came from smbd then it will probably be accompanied by
+a message which details the last SMB message received by smbd. This
+info is often very useful in tracking down the problem so please
+include it in your bug report.
+</p><p>
+You should also detail how to reproduce the problem, if
+possible. Please make this reasonably detailed.
+</p><p>
+You may also find that a core file appeared in a <tt>corefiles</tt>
+subdirectory of the directory where you keep your samba log
+files. This file is the most useful tool for tracking down the bug. To
+use it you do this:
+</p><p><b>gdb smbd core</b></p><p>
+adding appropriate paths to smbd and core so gdb can find them. If you
+don't have gdb then try <b><tt>dbx</tt></b>. Then within the debugger use the
+command <b><tt>where</tt></b> to give a stack trace of where the problem
+occurred. Include this in your mail.
+</p><p>
+If you know any assembly language then do a <b><tt>disass</tt></b> of the routine
+where the problem occurred (if its in a library routine then
+disassemble the routine that called it) and try to work out exactly
+where the problem is by looking at the surrounding code. Even if you
+don't know assembly then incuding this info in the bug report can be
+useful.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2887942"></a>Attaching to a running process</h2></div></div><p>
+Unfortunately some unixes (in particular some recent linux kernels)
+refuse to dump a core file if the task has changed uid (which smbd
+does often). To debug with this sort of system you could try to attach
+to the running process using <b><tt>gdb smbd <i><tt>PID</tt></i></tt></b> where you get <i><tt>PID</tt></i> from
+smbstatus. Then use <b><tt>c</tt></b> to continue and try to cause the core dump
+using the client. The debugger should catch the fault and tell you
+where it occurred.
+</p></div><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2887989"></a>Patches</h2></div></div><p>
+The best sort of bug report is one that includes a fix! If you send us
+patches please use <b><tt>diff -u</tt></b> format if your version of
+diff supports it, otherwise use <b><tt>diff -c4</tt></b>. Make sure
+you do the diff against a clean version of the source and let me know
+exactly what version you used.

+Before migrating a network from MS Windows NT4 to Samba-3 it is vital that all necessary factors are
+considered. Users should be educated about changes they may experience so that the change will be a
+welcome one and not become an obstacle to the work they need to do. The following are some of the
+factors that will go into a successful migration:
+</p><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2889498"></a>Domain Layout</h4></div></div><p>
+Samba-3 can be configured as a domain controller, a back-up domain controller (probably best called
+a secondary controller), a domain member, or as a stand-alone server. The Windows network security
+domain context should be sized and scoped before implementation. Particular attention needs to be
+paid to the location of the primary domain controller (PDC) as well as backup controllers (BDCs).
+It should be noted that one way in which Samba-3 differs from Microsoft technology is that if one
+chooses to use an LDAP authentication backend then the same database can be used by several different
+domains. This means that in a complex organisation there can be a single LDAP database, that itself
+can be distributed, that can simultaneously serve multiple domains (that can also be widely distributed).
+</p><p>
+It is recommended that from a design perspective, the number of users per server, as well as the number
+of servers, per domain should be scaled according to needs and should also consider server capacity
+and network bandwidth.
+</p><p>
+A physical network segment may house several domains, each of which may span multiple network segments.
+Where domains span routed network segments it is most advisable to consider and test the performance
+implications of the design and layout of a network. A Centrally located domain controller that is being
+designed to serve mulitple routed network segments may result in severe performance problems if the
+response time (eg: ping timing) between the remote segment and the PDC is more than 100 ms. In situations
+where the delay is too long it is highly recommended to locate a backup controller (BDC) to serve as
+the local authentication and access control server.
+</p></div><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2889551"></a>Server Share and Directory Layout</h4></div></div><p>
+There are few cardinal rules to effective network design that can be broken with impunity.
+The most important rule of effective network management is that simplicity is king in every
+well controlled network. Every part of the infrastructure must be managed, the more complex
+it is, the greater will be the demand of keeping systems secure and functional.
+</p><p>
+The nature of the data that must be stored needs to be born in mind when deciding how many
+shares must be created. The physical disk space layout should also be taken into account
+when designing where share points will be created. Keep in mind that all data needs to be
+backed up, thus the simpler the disk layout the easier it will be to keep track of what must
+be backed up to tape or other off-line storage medium. Always plan and implement for minimum
+maintenance. Leave nothing to chance in your design, above all, do not leave backups to chance:
+Backup and test, validate every backup, create a disaster recovery plan and prove that it works.
+</p><p>
+Users should be grouped according to data access control needs. File and directory access
+is best controlled via group permissions and the use of the &quot;sticky bit&quot; on group controlled
+directories may substantially avoid file access complaints from samba share users.
+</p><p>
+Many network administrators who are new to the game will attempt to use elaborate techniques
+to set access controls, on files, directories, shares, as well as in share definitions.
+There is the ever present danger that that administrator's successor will not understand the
+complex mess that has been inherited. Remember, apparent job security through complex design
+and implementation may ultimately cause loss of operations and downtime to users as the new
+administrator learns to untangle your web. Keep access controls simple and effective and
+make sure that users will never be interrupted by the stupidity of complexity.
+</p></div><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2889612"></a>Logon Scripts</h4></div></div><p>
+Please refer to the section of this document on Advanced Network Adminsitration for information
+regarding the network logon script options for Samba-3. Logon scripts can help to ensure that
+all users gain share and printer connections they need.
+</p><p>
+Logon scripts can be created on-the-fly so that all commands executed are specific to the
+rights and privilidges granted to the user. The preferred controls should be affected through
+group membership so that group information can be used to custom create a logong script using
+the <tt>root preexec</tt> parameters to the <tt>NETLOGON</tt> share.
+</p><p>
+Some sites prefer to use a tool such as <tt>kixstart</tt> to establish a controlled
+user environment. In any case you may wish to do a google search for logon script process controls.
+In particular, you may wish to explore the use of the Microsoft knowledgebase article KB189105 that
+deals with how to add printers without user intervention via the logon script process.
+</p></div><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2889670"></a>Profile Migration/Creation</h4></div></div><p>
+User and Group Profiles may be migrated using the tools described in the section titled Desktop Profile
+Management.
+</p><p>
+Profiles may also be managed using the Samba-3 tool <tt>profiles</tt>. This tool allows
+the MS Windows NT style security identifiers (SIDs) that are stored inside the profile NTuser.DAT file
+to be changed to the SID of the Samba-3 domain.
+</p></div><div class="sect3" lang="en"><div class="titlepage"><div><h4 class="title"><a name="id2889700"></a>User and Group Accounts</h4></div></div><p>
+It is possible to migrate all account settings from an MS Windows NT4 domain to Samba-3. Before
+attempting to migrate user and group accounts it is STRONGLY advised to create in Samba-3 the
+groups that are present on the MS Windows NT4 domain <span class="emphasis"><em>AND</em></span> to connect these to

+should migrate painlessly.

clients (when not operating as a PDC), Samba must have

+<b>nt acl support = no</b>
added to the file share which houses the roaming profiles.
If this is not done, then the Windows 2000 SP2 client will
complain about not being able to access the profile (Access
Denied) and create multiple copies of it on disk (DOMAIN.user.001,
DOMAIN.user.002, etc...). See the

+There are many and varied opinions regarding the usefulness or otherwise of SWAT.
+No matter how hard one tries to produce the perfect configuration tool it remains
+an object of personal taste. SWAT is a tool that will allow web based configuration
+of samba. It has a wizard that may help to get samba configured quickly, it has context
+sensitive help on each smb.conf parameter, it provides for monitoring of current state
+of connection information, and it allows network wide MS Windows network password
+management.
+</p><div class="sect1" lang="en"><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="id2890961"></a>SWAT Features and Benefits</h2></div></div><p>
+There are network administrators who believe that it is a good idea to write systems
+documentation inside configuration files, for them SWAT will aways be a nasty tool. SWAT
+does not store the configuration file in any intermediate form, rather, it stores only the
+parameter settings, so when SWAT writes the smb.conf file to disk it will write only
+those parameters that are at other than the default settings. The result is that all comments
+will be lost from the smb.conf file. Additionally, the parameters will be written back in
+internal ordering.
+</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
+So before using SWAT please be warned - SWAT will completely replace your smb.conf with
+a fully optimised file that has been stripped of all comments you might have placed there
+and only non-default settings will be written to the file.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2890837"></a>Enabling SWAT for use</h3></div></div><p>
+SWAT should be installed to run via the network super daemon. Depending on which system
+your Unix/Linux system has you will have either an <tt>inetd</tt> or
+<tt>xinetd</tt> based system.
+</p><p>
+The nature and location of the network super-daemon varies with the operating system
+implementation. The control file (or files) can be located in the file
+<tt>/etc/inetd.conf</tt> or in the directory <tt>/etc/[x]inet.d</tt>
+or similar.
+</p><p>
+The control entry for the older style file might be:
+</p><pre class="programlisting">
+ # swat is the Samba Web Administration Tool
+ swat stream tcp nowait.400 root /usr/sbin/swat swat
+</pre><p>
+A control file for the newer style xinetd could be:
+</p><p>
+</p><pre class="programlisting">
+ # default: off
+ # description: SWAT is the Samba Web Admin Tool. Use swat \
+ # to configure your Samba server. To use SWAT, \
+ # connect to port 901 with your favorite web browser.
+ service swat
+ {
+ port = 901
+ socket_type = stream
+ wait = no
+ only_from = localhost
+ user = root
+ server = /usr/sbin/swat
+ log_on_failure += USERID
+ disable = yes
+ }
+</pre><p>
+
+</p><p>
+Both the above examples assume that the <tt>swat</tt> binary has been
+located in the <tt>/usr/sbin</tt> directory. In addition to the above
+SWAT will use a directory access point from which it will load it's help files
+as well as other control information. The default location for this on most Linux
+systems is in the directory <tt>/usr/share/samba/swat</tt>. The default
+location using samba defaults will be <tt>/usr/local/samba/swat</tt>.
+</p><p>
+Access to SWAT will prompt for a logon. If you log onto SWAT as any non-root user
+the only permission allowed is to view certain aspects of configuration as well as
+access to the password change facility. The buttons that will be exposed to the non-root
+user are: <span class="emphasis"><em>HOME, STATUS, VIEW, PASSWORD</em></span>. The only page that allows
+change capability in this case is <span class="emphasis"><em>PASSWORD</em></span>.
+</p><p>
+So long as you log onto SWAT as the user <b>root</b> you should obtain
+full change and commit ability. The buttons that will be exposed includes:
+<span class="emphasis"><em>HOME, GLOBALS, SHARES, PRINTERS, WIZARD, STATUS, VIEW, PASSWORD</em></span>.

+Lots of people have asked about how to setup SWAT with SSL to allow for secure remote
+administration of Samba. Here is a method that works, courtesy of Markus Krieger
+</p><p>
+Modifications to the swat setup are as following:
+</p><div class="itemizedlist"><ul type="disc"><li><p>
+ install OpenSSL
+ </p></li><li><p>
+ generate certificate and private key
+
+ </p><pre class="programlisting">

+</p><p>
+Administrators who wish to validate their samba configuration may obtain useful information
+from the man pages for the diganostic utilities. These are available from the SWAT home page

+The purpose if the SWAT Wizard is to help the Microsoft knowledgable network administrator
+to configure Samba with a minimum of effort.
+</p><p>
+The Wizard page provides a tool for rewiting the smb.conf file in fully optimised format.
+This will also happen if you press the commit button. The two differ in the the rewrite button

+The <span class="emphasis"><em>Edit</em></span> button permits the editing (setting) of the minimal set of
+options that may be necessary to create a working samba server.
+</p><p>
+Finally, there are a limited set of options that will determine what type of server samba
+will be configured for, whether it will be a WINS server, participate as a WINS client, or
+operate with no WINS support. By clicking on one button you can elect to epose (or not) user
+home directories.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2892261"></a>The Status Page</h3></div></div><p>
+The status page serves a limited purpose. Firstly, it allows control of the samba daemons.
+The key daemons that create the samba server environment are: <b> smbd, nmbd, winbindd</b>.
+</p><p>
+The daemons may be controlled individually or as a total group. Additionally, you may set
+an automatic screen refresh timing. As MS Windows clients interact with Samba new smbd processes
+will be continually spawned. The auto-refresh facility will allow you to track the changing
+conditions with minimal effort.
+</p><p>
+Lastly, the Status page may be used to terminate specific smbd client connections in order to
+free files that may be locked.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2892300"></a>The View Page</h3></div></div><p>
+This page allows the administrator to view the optimised smb.conf file and if you are

+parameters and their settings.
+</p></div><div class="sect2" lang="en"><div class="titlepage"><div><h3 class="title"><a name="id2892316"></a>The Password Change Page</h3></div></div><p>
+The Password Change page is a popular tool. This tool allows the creation, deletion, deactivation
+and reactivation of MS Windows networking users on the local machine. Alternatively, you can use
+this tool to change a local password for a user account.
+</p><p>
+When logged in as a non-root account the user will have to provide the old password as well as
+the new password (twice). When logged in as <b>root</b> only the new password is
+required.
+</p><p>
+One popular use for this tool is to change user passwords across a range of remote MS Windows

+The Samba server uses TCP to talk to the client. Thus if you are
trying to see if it performs well you should really compare it to
programs that use the same protocol. The most readily available
programs for file transfer that use TCP are ftp or another TCP based
-SMB server.</P

+If you want to test against something like a NT or WfWg server then

+Several people have done comparisons between Samba and Novell, NFS or

+Often a speed problem can be traced to the client. The client (for
example Windows for Workgroups) can often be tuned for better TCP
-performance.</P
-><P
->See your client docs for details. In particular, I have heard rumours
-that the WfWg options TCPWINDOWSIZE and TCPSEGMENTSIZE can have a
-large impact on performance.</P
-><P
->Also note that some people have found that setting DefaultRcvWindow in
-the [MSTCP] section of the SYSTEM.INI file under WfWg to 3072 gives a
-big improvement. I don't know why.</P
-><P
->My own experience wth DefaultRcvWindow is that I get much better
-performance with a large value (16384 or larger). Other people have
-reported that anything over 3072 slows things down enourmously. One
-person even reported a speed drop of a factor of 30 when he went from
-3072 to 8192. I don't know why.</P
-><P
->It probably depends a lot on your hardware, and the type of unix box
-you have at the other end of the link.</P
-><P
->Paul Cochrane has done some testing on client side tuning and come
-to the following conclusions:</P
-><P
->Install the W2setup.exe file from www.microsoft.com. This is an
-update for the winsock stack and utilities which improve performance.</P
-><P
->Configure the win95 TCPIP registry settings to give better
-perfomance. I use a program called MTUSPEED.exe which I got off the
-net. There are various other utilities of this type freely available.
-The setting which give the best performance for me are:</P

- hosts allow = xxx.xxx.xxx.xxx/yy 127.</PRE
-></P
-><P
->Do NOT use the <B

-connections. (Note: the <B
-CLASS="COMMAND"
->bind interfaces only</B
-> parameter deficiency
-where it will not allow connections to the loopback address will be

->Another common cause of these two errors is having something already running
-on port 139, such as Samba (ie: smbd is running from <SPAN

-something like Digital's Pathworks. Check your <TT

->One of the best diagnostic tools for debugging problems is Samba itself.
-You can use the -d option for both smbd and nmbd to specify what

-smb.conf for more information on debugging options. The debug
-level can range from 1 (the default) to 10 (100 for debugging passwords).</P

->Another helpful method of debugging is to compile samba using the

-information in the binaries and allow you to attach gdb to the
-running smbd / nmbd process. In order to attach gdb to an smbd
-process for an NT workstation, first get the workstation to make the
-connection. Pressing ctrl-alt-delete and going down to the domain box

->If the bug has anything to do with Samba behaving incorrectly as a
-server (like refusing to open a file) then the log files will probably
-be very useful. Depending on the problem a log level of between 3 and
-10 showing the problem may be appropriate. A higher level givesmore

-<TT
-CLASS="FILENAME"

-level higher for just one machine and keep separate logs for each machine.
-To do this use:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
->log level = 10
-log file = /usr/local/samba/lib/log.%m
-include = /usr/local/samba/lib/smb.conf.%m</PRE

-put any <TT
-CLASS="FILENAME"
->smb.conf</TT
-> commands you want, for example
-<B
-CLASS="COMMAND"
->log level=</B
-> may be useful. This also allows you to
-experiment with different security systems, protocol levels etc on just
-one machine.</P
-><P
->The <TT
-CLASS="FILENAME"
->smb.conf</TT

-CLASS="COMMAND"
->log level =</B

-> files.</P
-><P
->As the <B
-CLASS="COMMAND"
->log level =</B
-> value is increased you will record
-a significantly increasing level of debugging information. For most
