It might be because you are using a uid +or gid of 65535 or -1. This is a VERY bad idea, and is a big security +hole. Check carefully in your /etc/passwd file and make sure that no +user has uid 65535 or -1. Especially check the "nobody" user, as many +broken systems are shipped with nobody setup with a uid of 65535.</P> +<P>It might also mean that your OS has a trapdoor uid/gid system :-)</P> +<P>This means that once a process changes effective uid from root to +another user it can't go back to root. Unfortunately Samba relies on +being able to change effective uid from root to non-root and back +again to implement its security policy. If your OS has a trapdoor uid +system this won't work, and several things in Samba may break. Less +things will break if you use user or server level security instead of +the default share level security, but you may still strike +problems.</P> +<P>The problems don't give rise to any security holes, so don't panic, +but it does mean some of Samba's capabilities will be unavailable. +In particular you will not be able to connect to the Samba server as +two different uids at once. This may happen if you try to print as a +"guest" while accessing a share as a normal user. It may also affect +your ability to list the available shares as this is normally done as +the guest user.</P> +<P>Complain to your OS vendor and ask them to fix their system.</P> +<P>Note: the reason why 65535 is a VERY bad choice of uid and gid is that +it casts to -1 as a uid, and the setreuid() system call ignores (with +no error) uid changes to -1. This means any daemon attempting to run +as uid 65535 will actually run as root.

If it +is, the problem is most likely name resolution. + +If your client has a facility to do so, hardcode a mapping between the +hosts IP and the name you want to use. For example, with Man Manager +or Windows for Workgroups you would put a suitable entry in the file +LMHOSTS. If this works, the problem is in the communication between +your client and the netbios name server. If it does not work, then +there is something fundamental wrong with your naming and the solution +is beyond the scope of this document. + +If you do not have any server on your subnet supplying netbios name +resolution, hardcoded mappings are your only option. If you DO have a +netbios name server running (such as the Samba suite's nmbd program), +the problem probably lies in the way it is set up. Refer to Section +Two of this FAQ for more ideas. + +By the way, remember to REMOVE the hardcoded mapping before further +tests :-) + +<sect1>My client reports "cannot locate specified share name" or similar<p> <label id="cant_see_share"> +This message indicates that your client CAN locate the specified +server, which is a good start, but that it cannot find a service of +the name you gave. + +The first step is to check the exact name of the service you are +trying to connect to (consult your system administrator).

Search for the printer name and +see if the log turns up any clues. Note that error messages to do with +a service ipc$ are meaningless - they relate to the way the client +attempts to retrieve status information when using the LANMAN1 +protocol. + +If using WfWg then you need to set the default protocol to TCP/IP, not +Netbeui. This is a WfWg bug. + +If using the Lanman1 protocol (the default) then try switching to +coreplus. Also not that print status error messages don't mean +printing won't work. The print status is received by a different +mechanism. + +<sect1>My programs install on the server OK, but refuse to work properly<p><label id="programs_wont_run"> +There are numerous possible reasons for this, but one MAJOR +possibility is that your software uses locking. Make sure you are +using Samba 1.6.11 or later. It may also be possible to work around +the problem by setting "locking=no" in the Samba configuration file +for the service the software is installed on. This should be regarded +as a strictly temporary solution. + +In earlier Samba versions there were some difficulties with the very +latest Microsoft products, particularly Excel 5 and Word for Windows +6.

"Samba 1.9.15p4", instead +of what I have changed it to in the smb.conf file. + +You need to use the -C option in nmbd. The "server string" affects +what smbd puts out and -C affects what nmbd puts out. + +Current versions of Samba (1.9.16 +) have combined these options into +the "server string" field of smb.conf, -C for nmbd is now obsolete. + +<sect1>My client reports "This server is not configured to list shared resources" <p> <label id="cant_list_shares"> +Your guest account is probably invalid for some reason.

Try creating another guest user other +than "nobody". + +<sect2>Log message "you appear to have a trapdoor uid system" <p><label id="trapdoor_uid"> +This can have several causes. It might be because you are using a uid +or gid of 65535 or -1. This is a VERY bad idea, and is a big security +hole. Check carefully in your /etc/passwd file and make sure that no +user has uid 65535 or -1. Especially check the "nobody" user, as many +broken systems are shipped with nobody setup with a uid of 65535. + +It might also mean that your OS has a trapdoor uid/gid system :-) + +This means that once a process changes effective uid from root to +another user it can't go back to root. Unfortunately Samba relies on +being able to change effective uid from root to non-root and back +again to implement its security policy. If your OS has a trapdoor uid +system this won't work, and several things in Samba may break. Less +things will break if you use user or server level security instead of +the default share level security, but you may still strike +problems. + +The problems don't give rise to any security holes, so don't panic, +but it does mean some of Samba's capabilities will be unavailable. +In particular you will not be able to connect to the Samba server as +two different uids at once. This may happen if you try to print as a +"guest" while accessing a share as a normal user. It may also affect +your ability to list the available shares as this is normally done as +the guest user. + +Complain to your OS vendor and ask them to fix their system. + +Note: the reason why 65535 is a VERY bad choice of uid and gid is that +it casts to -1 as a uid, and the setreuid() system call ignores (with +no error) uid changes to -1. This means any daemon attempting to run +as uid 65535 will actually run as root.

Initially +written for Unix, Samba now also runs on Netware, OS/2, VMS, StratOS and +Amigas. Ports to BeOS and other operating systems are underway. Samba +gives the capability for these operating systems to behave much like a +LAN Server, Windows NT Server or Pathworks machine, only with added +functionality and flexibility designed to make life easier for +administrators. </P> +<P>This means that using Samba you can share a server's disks and printers +to many sorts of network clients, including Lan Manager, Windows for +Workgroups, Windows NT, Linux, OS/2, and AIX. There is also a generic +client program supplied as part of the Samba suite which gives a user on +the server an ftp-like interface to access filespace and printers on any +other SMB/CIFS servers.</P> +<P>SMB has been implemented over many protocols, including XNS, NBT, IPX, +NetBEUI and TCP/IP. Samba only uses TCP/IP. This is not likely to change +although there have been some requests for NetBEUI support.</P> +<P>Many users report that compared to other SMB implementations Samba is +more stable, faster, and compatible with more clients. Administrators of +some large installations say that Samba is the only SMB server available +which will scale to many tens of thousands of users without crashing. +The easy way to test these claims is to download it and try it for +yourself!</P> +<P>The suite is supplied with full source code under the +<A HREF="../COPYING">GNU Public License</A>. The GPL means that you can +use Samba for whatever purpose you wish (including changing the source +or selling it for money) but under all circumstances the source code +must be made freely available. A copy of the GPL must always be included +in any copy of the package.</P> +<P>The primary creator of the Samba suite is Andrew Tridgell. Later +versions incorporate much effort by many net.helpers. The man pages +and this FAQ were originally written by Karl Auer.</P> + + +<H2><A NAME="ss2.2">2.2 What is the current version of Samba?</A></H2> + +<P> +<A NAME="current_version"></A> +</P> +<P>At time of writing, the current version was 1.9.17.

Samba is +distributed ONLY in source form, though binaries may be available from +other sites. Most Linux distributions, for example, do contain Samba +binaries for that platform. The VMS, OS/2, Netware and Amiga and other +ports typically have binaries made available.</P> +<P>A special case is vendor-provided binary packages. Samba binaries and +default configuration files are put into packages for a specific +operating system. RedHat Linux and Sun Solaris (Sparc and x86) is +already included, and others such as OS/2 may follow.

Many, many people just get the latest +recommended stable release version and are happy. If you are brave, by +all means take the plunge and help with the testing and development - +but don't install it on your departmental server. Samba is typically +very stable and safe, and this is mostly due to the policy of many +public releases.</P> +<P>How the scheme works:</P> +<P> +<OL> +<LI>When major changes are made the version number is increased.

These are for testing by those who know what they are +doing. The "alpha" in the filename will hopefully scare off those who +are just looking for the latest version to install. +</LI> +<LI>When Andrew thinks that the alphas have stabilised to the point +where he would recommend new users install it, he renames it to the +same version number without the alpha, for example 1.9.17. +</LI> +<LI>Inevitably bugs are found in the "stable" releases and minor patch +levels are released which give us the pXX series, for example 1.9.17p2. +</LI> +</OL> +</P> +<P>So the progression goes:</P> +<P> +<PRE> + 1.9.16p10 (production) + 1.9.16p11 (production) + 1.9.17alpha1 (test sites only) + : + 1.9.17alpha20 (test sites only) + 1.9.17 (production) + 1.9.17p1 (production) +</PRE> +</P> +<P>The above system means that whenever someone looks at the samba ftp +site they will be able to grab the highest numbered release without an +alpha in the name and be sure of getting the current recommended +version.</P> + + +<H2><A NAME="ss2.5">2.5 Where can I go for further information?</A></H2> + +<P> +<A NAME="more"></A> +</P> +<P>There are a number of places to look for more information on Samba, +including:</P> +<P> +<UL> +<LI>Two mailing lists devoted to discussion of Samba-related matters. +See below for subscription information. +</LI> +<LI>The newsgroup comp.protocols.smb, which has a great deal of +discussion about Samba. +</LI> +<LI>The WWW site 'SAMBA Web Pages' at +<A HREF="http://samba.anu.edu.au/samba/">http://samba.anu.edu.au/samba/</A> includes: + +<UL> +<LI>Links to man pages and documentation, including this FAQ</LI> +<LI>A comprehensive survey of Samba users</LI> +<LI>A searchable hypertext archive of the Samba mailing list</LI> +<LI>Links to Samba source code, binaries, and mirrors of both</LI> +<LI>This FAQ and the rest in its family</LI> +</UL> + +</LI> +</UL> +</P> + + +<H2><A NAME="ss2.6">2.6 How do I subscribe to the Samba Mailing Lists?</A></H2> + +<P> +<A NAME="mailinglist"></A> +</P> +<P>Send email to +<A HREF="mailto:listproc@samba.anu.edu.au">listproc@samba.anu.edu.au</A>.

Names for this protocol include LAN Manager and Microsoft +Networking. Parts of the specification has been made public at several +versions including in an X/Open document, as listed at +<A HREF="ftp://ftp.microsoft.com/developr/drg/CIFS/">ftp://ftp.microsoft.com/developr/drg/CIFS/</A>. No specification +releases were made between 1992 and 1996, and during that period +Microsoft became the SMB implementor with the largest market share. +Microsoft developed the specification further for its products but for +various reasons connected with developer's workload rather than market +strategy did not make the changes public. This culminated with the +"Windows NT 0.12" version released with NT 3.5 in 1995 which had significant +improvements and bugs. Because Microsoft client systems are so popular, +it is fair to say that what Microsoft with Windows affects all suppliers +of SMB server products.</P> +<P>From 1994 Andrew Tridgell began doing some serious work on his +Smbserver (now Samba) product and with some helpers started to +implement more and more of these protocols. Samba began to take +a significant share of the SMB server market.</P> + + +<H2><A NAME="ss3.2">3.2 What is the Common Internet Filesystem (CIFS)?</A></H2> + +<P>The initial pressure for Microsoft to document their current SMB +implementation came from the Samba team, who kept coming across things +on the wire that Microsoft either didn't know about or hadn't documented +anywhere (even in the sourcecode to Windows NT.) Then Sun Microsystems +came out with their WebNFS initiative, designed to replace FTP for file +transfers on the Internet. There are many drawbacks to WebNFS (including +its scope - it aims to replace HTTP as well!) but the concept was +attractive. FTP is not very clever, and why should it be harder to get +files from across the world than across the room? </P> +<P>Some hasty revisions were made and an Internet Draft for the Common +Internet Filesystem (CIFS) was released. Note that CIFS is not an +Internet standard and is a very long way from becoming one, BUT the +protocol specification is in the public domain and ongoing discussions +concerning the spec take place on a public mailing list according to the +rules of the Internet Engineering Task Force. For more information and +pointers see +<A HREF="http://samba.anu.edu.au/cifs/">http://samba.anu.edu.au/cifs/</A></P> +<P>The following is taken from +<A HREF="http://www.microsoft.com/intdev/cifs/">http://www.microsoft.com/intdev/cifs/</A></P> +<P> +<PRE> + CIFS defines a standard remote file system access protocol for use + over the Internet, enabling groups of users to work together and + share documents across the Internet or within their corporate + intranets. CIFS is an open, cross-platform technology based on the + native file-sharing protocols built into Microsoft® Windows® and + other popular PC operating systems, and supported on dozens of + other platforms, including UNIX®. With CIFS, millions of computer + users can open and share remote files on the Internet without having + to install new software or change the way they work." +</PRE> +</P> +<P>If you consider CIFS as a backwardsly-compatible refinement of SMB that +will work reasonably efficiently over the Internet you won't be too far +wrong.</P> +<P>The net effect is that Microsoft is now documenting large parts of their +Windows NT fileserver protocols. The security concepts embodied in +Windows NT are part of the specification, which is why Samba +documentation often talks in terms of Windows NT. However there is no +reason why a site shouldn't conduct all its file and printer sharing +with CIFS and yet have no Microsoft products at all.</P> + + +<H2><A NAME="ss3.3">3.3 What is Browsing? </A></H2> + +<P>The term "Browsing" causes a lot of confusion. It is the part of the +SMB/CIFS protocol which allows for resource discovery. For example, in +the Windows NT Explorer it is possible to see a "Network Neighbourhood" +of computers in the same SMB workgroup. Clicking on the name of one of +these machines brings up a list of file and printer resources for +connecting to. In this way you can cruise the network, seeing what +things are available. How this scales to the Internet is a subject for +debate.

Some kind of distributed authentication database is associated +with a domain (there are quite a few choices) and this adds so much +flexibility that many people think of a domain as a completely different +entity to a workgroup. From Samba's point of view a client connecting to +a service presents an authentication token, and it if it is valid they +have access. Samba does not care what mechanism was used to generate +that token in the first place.</P> +<P>The SMB client logging on to a domain has an expectation that every other +server in the domain should accept the same authentication information. +However the network browsing functionality of domains and workgroups is +identical and is explained in +<A HREF="../BROWSING.txt">../BROWSING.txt</A>.</P> +<P>There are some implementation differences: Windows 95 can be a member of +both a workgroup and a domain, but Windows NT cannot. Windows 95 also +has the concept of an "alternative workgroup". Samba can only be a +member of a single workgroup or domain, although this is due to change +with a future version when nmbd will be split into two daemons, one for +WINS and the other for browsing ( +<A HREF="../NetBIOS.txt">../NetBIOS.txt</A> explains +what WINS is.)</P> + +<H3>Defining the Terms</H3> + +<P> +<A NAME="BrowseAndDomainDefs"></A> +</P> +<P> +<DL> + +<DT><B>Workgroup</B><DD><P>means a collection of machines that maintain a common +browsing database containing information about their shared resources. +They do not necessarily have any security information in common (if they +do, it gets called a Domain.) The browsing database is dynamic, modified +as servers come and go on the network and as resources are added or +deleted. The term "browsing" refers to a user accessing the database via +whatever interface the client provides, eg the OS/2 Workplace Shell or +Windows 95 Explorer. SMB servers agree between themselves as to which +ones will maintain the browsing database. Workgroups can be anywhere on +a connected TCP/IP network, including on different subnets or even on +the Interet. This is a very tricky part of SMB to implement.</P> + +<DT><B>Master Browsers</B><DD><P>are machines which holds the master browsing +database for a workgroup or domain. There are two kinds of Master Browser:</P> +<P> +<UL> +<LI> Domain Master Browser, which holds the master browsing +information for an entire domain, which may well cross multiple TCP/IP +subnets. +</LI> +<LI> Local Master Browser, which holds the master browsing database +for a particular subnet and communicates with the Domain Master Browser +to get information on other subnets. +</LI> +</UL> +</P> +<P>Subnets are differentiated because browsing is based on broadcasts, and +broadcasts do not pass through routers. Subnets are not routed: while it +is possible to have more than one subnet on a single network segment +this is regarded as very bad practice.</P> +<P>Master Browsers (both Domain and Local) are elected dynamically +according to an algorithm which is supposed to take into account the +machine's ability to sustain the browsing load. Samba can be configured +to always act as a master browser, ie it always wins elections under all +circumstances, even against systems such as a Windows NT Primary Domain +Controller which themselves expect to win. </P> +<P>There are also Backup Browsers which are promoted to Master Browsers in +the event of a Master Browser disappearing from the network.</P> +<P>Alternative terms include confusing variations such as "Browse Master", +and "Master Browser" which we are trying to eliminate from the Samba +documentation. </P> + +<DT><B>Domain Controller</B><DD><P>is a term which comes from the Microsoft and IBM +etc implementation of the LAN Manager protocols. It is tied to +authentication. There are other ways of doing domain authentication, but +the Windows NT method has a large market share. The general issues are +discussed in +<A HREF="../DOMAIN.txt">../DOMAIN.txt</A> and a Windows NT-specific +discussion is in +<A HREF="../DOMAIN_CONTROL.txt">../DOMAIN_CONTROL.txt</A>.</P> + +</DL> +</P> + +<H3>Sharelevel (Workgroup) Security Services</H3> + +<P> +<A NAME="ShareModeSecurity"></A> +</P> +<P>With the Samba setting "security = SHARE", all shared resources +information about what password is associated with them but only hints +as to what usernames might be valid (the hint can be 'all users', in +which case any username will work. This is usually a bad idea, but +reflects both the initial implementations of SMB in the mid-80s and +its reincarnation with Windows for Workgroups in 1992. The idea behind +workgroup security was that small independant groups of people could +share information on an ad-hoc basis without there being an +authentication infrastructure present or requiring them to do more than +fill in a dialogue box.</P> + +<H3>Authentication Domain Mode Services</H3> + +<P> +<A NAME="DomainModeSecurity"></A> +</P> +<P>With the Samba settings "security = USER" or "security = SERVER" +accesses to all resources are checked for username/password pair matches +in a more rigorous manner. To the client, this has the effect of +emulating a Microsoft Domain. The client is not concerned whether or not +Samba looks up a Windows NT SAM or does it in some other way.</P> + + +<H2><A NAME="ss4.2">4.2 Authentication Schemes</A></H2> + + +<P>In the simple case authentication information is stored on a single +server and the user types a password on connecting for the first time. +However client operating systems often require a password before they +can be used at all, and in addition users usually want access to more +than one server. Asking users to remember many different passwords in +different contexts just does not work. Some kind of distributed +authentication database is needed. It must cope with password changes +and provide for assigning groups of users the same level of access +permissions. This is why Samba installations often choose to implement a +Domain model straight away.</P> +<P>Authentication decisions are some of the biggest in designing a network. +Are you going to use a scheme native to the client operating system, +native to the server operating system, or newly installed on both?

Initially +written for Unix, Samba now also runs on Netware, OS/2, VMS, StratOS and +Amigas. Ports to BeOS and other operating systems are underway. Samba +gives the capability for these operating systems to behave much like a +LAN Server, Windows NT Server or Pathworks machine, only with added +functionality and flexibility designed to make life easier for +administrators. + +This means that using Samba you can share a server's disks and printers +to many sorts of network clients, including Lan Manager, Windows for +Workgroups, Windows NT, Linux, OS/2, and AIX. There is also a generic +client program supplied as part of the Samba suite which gives a user on +the server an ftp-like interface to access filespace and printers on any +other SMB/CIFS servers. + +SMB has been implemented over many protocols, including XNS, NBT, IPX, +NetBEUI and TCP/IP. Samba only uses TCP/IP. This is not likely to change +although there have been some requests for NetBEUI support. + +Many users report that compared to other SMB implementations Samba is +more stable, faster, and compatible with more clients. Administrators of +some large installations say that Samba is the only SMB server available +which will scale to many tens of thousands of users without crashing. +The easy way to test these claims is to download it and try it for +yourself! + +The suite is supplied with full source code under the <url +url="../COPYING" name="GNU Public License">. The GPL means that you can +use Samba for whatever purpose you wish (including changing the source +or selling it for money) but under all circumstances the source code +must be made freely available. A copy of the GPL must always be included +in any copy of the package. + +The primary creator of the Samba suite is Andrew Tridgell. Later +versions incorporate much effort by many net.helpers. The man pages +and this FAQ were originally written by Karl Auer. + +<sect1> What is the current version of Samba?<p><label id="current_version"> + +At time of writing, the current version was 1.9.17. If you want to be +sure check the bottom of the change-log file. <url url="ftp://samba.anu.edu.au/pub/samba/alpha/change-log"> + +For more information see <ref id="version_nums" name="What do the version numbers mean?"> + +<sect1> Where can I get it? <p><label id="WhereFrom"> + +The Samba suite is available via anonymous ftp from samba.anu.edu.au and +many <url url="../MIRRORS" name="mirror"> sites.

Names for this protocol include LAN Manager and Microsoft +Networking. Parts of the specification has been made public at several +versions including in an X/Open document, as listed at +<url url="ftp://ftp.microsoft.com/developr/drg/CIFS/">. No specification +releases were made between 1992 and 1996, and during that period +Microsoft became the SMB implementor with the largest market share. +Microsoft developed the specification further for its products but for +various reasons connected with developer's workload rather than market +strategy did not make the changes public. This culminated with the +"Windows NT 0.12" version released with NT 3.5 in 1995 which had significant +improvements and bugs. Because Microsoft client systems are so popular, +it is fair to say that what Microsoft with Windows affects all suppliers +of SMB server products. + +From 1994 Andrew Tridgell began doing some serious work on his +Smbserver (now Samba) product and with some helpers started to +implement more and more of these protocols. Samba began to take +a significant share of the SMB server market. + +<sect1> What is the Common Internet Filesystem (CIFS)?<p> +The initial pressure for Microsoft to document their current SMB +implementation came from the Samba team, who kept coming across things +on the wire that Microsoft either didn't know about or hadn't documented +anywhere (even in the sourcecode to Windows NT.) Then Sun Microsystems +came out with their WebNFS initiative, designed to replace FTP for file +transfers on the Internet. There are many drawbacks to WebNFS (including +its scope - it aims to replace HTTP as well!) but the concept was +attractive. FTP is not very clever, and why should it be harder to get +files from across the world than across the room? + +Some hasty revisions were made and an Internet Draft for the Common +Internet Filesystem (CIFS) was released. Note that CIFS is not an +Internet standard and is a very long way from becoming one, BUT the +protocol specification is in the public domain and ongoing discussions +concerning the spec take place on a public mailing list according to the +rules of the Internet Engineering Task Force. For more information and +pointers see <url url="http://samba.anu.edu.au/cifs/"> + +The following is taken from <url url="http://www.microsoft.com/intdev/cifs/"> + +<verb> + CIFS defines a standard remote file system access protocol for use + over the Internet, enabling groups of users to work together and + share documents across the Internet or within their corporate + intranets. CIFS is an open, cross-platform technology based on the + native file-sharing protocols built into Microsoft® Windows® and + other popular PC operating systems, and supported on dozens of + other platforms, including UNIX®. With CIFS, millions of computer + users can open and share remote files on the Internet without having + to install new software or change the way they work." +</verb> + +If you consider CIFS as a backwardsly-compatible refinement of SMB that +will work reasonably efficiently over the Internet you won't be too far +wrong. + +The net effect is that Microsoft is now documenting large parts of their +Windows NT fileserver protocols. The security concepts embodied in +Windows NT are part of the specification, which is why Samba +documentation often talks in terms of Windows NT. However there is no +reason why a site shouldn't conduct all its file and printer sharing +with CIFS and yet have no Microsoft products at all. + +<sect1> What is Browsing? <p> +The term "Browsing" causes a lot of confusion. It is the part of the +SMB/CIFS protocol which allows for resource discovery. For example, in +the Windows NT Explorer it is possible to see a "Network Neighbourhood" +of computers in the same SMB workgroup. Clicking on the name of one of +these machines brings up a list of file and printer resources for +connecting to. In this way you can cruise the network, seeing what +things are available. How this scales to the Internet is a subject for +debate. Look at the CIFS list archives to see what the experts think. + +<sect>Designing A SMB and CIFS Network<p> + +The big issues for installing any network of LAN or WAN file and print +servers are + +<itemize> + +<item>How and where usernames, passwords and other security information +is stored + +<item>What method can be used for locating the resources that users have +permission to use + +<item>What protocols the clients can converse with + +</itemize> + +If you buy Netware, Windows NT or just about any other LAN fileserver +product you are expected to lock yourself into the product's preferred +answers to these questions. This tendancy is restrictive and often very +expensive for a site where there is only one kind of client or server, +and for sites with a mixture of operating systems it often makes it +impossible to share resources between some sets of users. + +The Samba philosophy is to make things as easy as possible for +administators, which means allowing as many combinations of clients, +servers, operating systems and protocols as possible. + +<sect1>Workgroups, Domains, Authentication and Browsing<p> + +From the point of view of networking implementation, Domains and +Workgroups are <em>exactly</em> the same, except for the client logon +sequence. Some kind of distributed authentication database is associated +with a domain (there are quite a few choices) and this adds so much +flexibility that many people think of a domain as a completely different +entity to a workgroup. From Samba's point of view a client connecting to +a service presents an authentication token, and it if it is valid they +have access. Samba does not care what mechanism was used to generate +that token in the first place. + +The SMB client logging on to a domain has an expectation that every other +server in the domain should accept the same authentication information. +However the network browsing functionality of domains and workgroups is +identical and is explained in <url url="../BROWSING.txt">. + +There are some implementation differences: Windows 95 can be a member of +both a workgroup and a domain, but Windows NT cannot. Windows 95 also +has the concept of an "alternative workgroup". Samba can only be a +member of a single workgroup or domain, although this is due to change +with a future version when nmbd will be split into two daemons, one for +WINS and the other for browsing (<url url="../NetBIOS.txt"> explains +what WINS is.) + +<sect2> Defining the Terms<p><label id="BrowseAndDomainDefs"> + +<descrip> + +<tag/Workgroup/ means a collection of machines that maintain a common +browsing database containing information about their shared resources. +They do not necessarily have any security information in common (if they +do, it gets called a Domain.) The browsing database is dynamic, modified +as servers come and go on the network and as resources are added or +deleted. The term "browsing" refers to a user accessing the database via +whatever interface the client provides, eg the OS/2 Workplace Shell or +Windows 95 Explorer. SMB servers agree between themselves as to which +ones will maintain the browsing database. Workgroups can be anywhere on +a connected TCP/IP network, including on different subnets or even on +the Interet. This is a very tricky part of SMB to implement. + +<tag/Master Browsers/ are machines which holds the master browsing +database for a workgroup or domain. There are two kinds of Master Browser: + +<itemize> + +<item> Domain Master Browser, which holds the master browsing +information for an entire domain, which may well cross multiple TCP/IP +subnets. + +<item> Local Master Browser, which holds the master browsing database +for a particular subnet and communicates with the Domain Master Browser +to get information on other subnets. + +</itemize> + +Subnets are differentiated because browsing is based on broadcasts, and +broadcasts do not pass through routers. Subnets are not routed: while it +is possible to have more than one subnet on a single network segment +this is regarded as very bad practice. + +Master Browsers (both Domain and Local) are elected dynamically +according to an algorithm which is supposed to take into account the +machine's ability to sustain the browsing load. Samba can be configured +to always act as a master browser, ie it always wins elections under all +circumstances, even against systems such as a Windows NT Primary Domain +Controller which themselves expect to win. + +There are also Backup Browsers which are promoted to Master Browsers in +the event of a Master Browser disappearing from the network. + +Alternative terms include confusing variations such as "Browse Master", +and "Master Browser" which we are trying to eliminate from the Samba +documentation. + +<tag/Domain Controller/ is a term which comes from the Microsoft and IBM +etc implementation of the LAN Manager protocols. It is tied to +authentication. There are other ways of doing domain authentication, but +the Windows NT method has a large market share. The general issues are +discussed in <url url="../DOMAIN.txt"> and a Windows NT-specific +discussion is in <url url="../DOMAIN_CONTROL.txt">. + +</descrip> + +<sect2>Sharelevel (Workgroup) Security Services<p><label id="ShareModeSecurity"> + +With the Samba setting "security = SHARE", all shared resources +information about what password is associated with them but only hints +as to what usernames might be valid (the hint can be 'all users', in +which case any username will work. This is usually a bad idea, but +reflects both the initial implementations of SMB in the mid-80s and +its reincarnation with Windows for Workgroups in 1992. The idea behind +workgroup security was that small independant groups of people could +share information on an ad-hoc basis without there being an +authentication infrastructure present or requiring them to do more than +fill in a dialogue box. + +<sect2>Authentication Domain Mode Services<p><label id="DomainModeSecurity"> + +With the Samba settings "security = USER" or "security = SERVER" +accesses to all resources are checked for username/password pair matches +in a more rigorous manner. To the client, this has the effect of +emulating a Microsoft Domain. The client is not concerned whether or not +Samba looks up a Windows NT SAM or does it in some other way. + +<sect1>Authentication Schemes<p> + +In the simple case authentication information is stored on a single +server and the user types a password on connecting for the first time. +However client operating systems often require a password before they +can be used at all, and in addition users usually want access to more +than one server. Asking users to remember many different passwords in +different contexts just does not work. Some kind of distributed +authentication database is needed. It must cope with password changes +and provide for assigning groups of users the same level of access +permissions. This is why Samba installations often choose to implement a +Domain model straight away. + +Authentication decisions are some of the biggest in designing a network. +Are you going to use a scheme native to the client operating system, +native to the server operating system, or newly installed on both?

WWhhaatt iiss SSaammbbaa?? + + + Samba is a suite of programs which work together to allow clients to + access to a server's filespace and printers via the SMB (Server + Message Block) and CIFS (Common Internet Filesystem) protocols. + Initially written for Unix, Samba now also runs on Netware, OS/2, VMS, + StratOS and Amigas. Ports to BeOS and other operating systems are + underway. Samba gives the capability for these operating systems to + behave much like a LAN Server, Windows NT Server or Pathworks machine, + only with added functionality and flexibility designed to make life + easier for administrators. + + This means that using Samba you can share a server's disks and + printers to many sorts of network clients, including Lan Manager, + Windows for Workgroups, Windows NT, Linux, OS/2, and AIX. There is + also a generic client program supplied as part of the Samba suite + which gives a user on the server an ftp-like interface to access + filespace and printers on any other SMB/CIFS servers. + + SMB has been implemented over many protocols, including XNS, NBT, IPX, + NetBEUI and TCP/IP. Samba only uses TCP/IP. This is not likely to + change although there have been some requests for NetBEUI support. + + Many users report that compared to other SMB implementations Samba is + more stable, faster, and compatible with more clients.

WWhhaatt ddoo tthhee vveerrssiioonn nnuummbbeerrss mmeeaann?? + + + It is not recommended that you run a version of Samba with the word + "alpha" in its name unless you know what you are doing and are willing + to do some debugging. Many, many people just get the latest + recommended stable release version and are happy. If you are brave, by + all means take the plunge and help with the testing and development - + but don't install it on your departmental server. Samba is typically + very stable and safe, and this is mostly due to the policy of many + public releases. + + How the scheme works: + + + 1. When major changes are made the version number is increased. For + example, the transition from 1.9.16 to 1.9.17. However, this + version number will not appear immediately and people should + continue to use 1.9.15 for production systems (see next point.) + + 2. Just after major changes are made the software is considered + unstable, and a series of alpha releases are distributed, for + example 1.9.16alpha1. These are for testing by those who know what + they are doing. The "alpha" in the filename will hopefully scare + off those who are just looking for the latest version to install. + + 3. When Andrew thinks that the alphas have stabilised to the point + where he would recommend new users install it, he renames it to the + same version number without the alpha, for example 1.9.17. + + 4. Inevitably bugs are found in the "stable" releases and minor patch + levels are released which give us the pXX series, for example + 1.9.17p2. + + So the progression goes: + + + 1.9.16p10 (production) + 1.9.16p11 (production) + 1.9.17alpha1 (test sites only) + : + 1.9.17alpha20 (test sites only) + 1.9.17 (production) + 1.9.17p1 (production) + + + + The above system means that whenever someone looks at the samba ftp + site they will be able to grab the highest numbered release without an + alpha in the name and be sure of getting the current recommended + version. + + + 22..55..

Names for this protocol include LAN Manager and Microsoft + Networking. Parts of the specification has been made public at several + versions including in an X/Open document, as listed at + <ftp://ftp.microsoft.com/developr/drg/CIFS/>. No specification + releases were made between 1992 and 1996, and during that period + Microsoft became the SMB implementor with the largest market share. + Microsoft developed the specification further for its products but for + various reasons connected with developer's workload rather than market + strategy did not make the changes public. This culminated with the + "Windows NT 0.12" version released with NT 3.5 in 1995 which had + significant improvements and bugs. Because Microsoft client systems + are so popular, it is fair to say that what Microsoft with Windows + affects all suppliers of SMB server products. + + From 1994 Andrew Tridgell began doing some serious work on his + Smbserver (now Samba) product and with some helpers started to + implement more and more of these protocols. Samba began to take a + significant share of the SMB server market. + + + 33..22.. WWhhaatt iiss tthhee CCoommmmoonn IInntteerrnneett FFiilleessyysstteemm ((CCIIFFSS))?? + + The initial pressure for Microsoft to document their current SMB + implementation came from the Samba team, who kept coming across things + on the wire that Microsoft either didn't know about or hadn't + documented anywhere (even in the sourcecode to Windows NT.) Then Sun + Microsystems came out with their WebNFS initiative, designed to + replace FTP for file transfers on the Internet. There are many + drawbacks to WebNFS (including its scope - it aims to replace HTTP as + well!) but the concept was attractive. FTP is not very clever, and why + should it be harder to get files from across the world than across the + room? + + Some hasty revisions were made and an Internet Draft for the Common + Internet Filesystem (CIFS) was released. Note that CIFS is not an + Internet standard and is a very long way from becoming one, BUT the + protocol specification is in the public domain and ongoing discussions + concerning the spec take place on a public mailing list according to + the rules of the Internet Engineering Task Force. For more information + and pointers see <http://samba.anu.edu.au/cifs/> + + The following is taken from <http://www.microsoft.com/intdev/cifs/> + + + CIFS defines a standard remote file system access protocol for use + over the Internet, enabling groups of users to work together and + share documents across the Internet or within their corporate + intranets. CIFS is an open, cross-platform technology based on the + native file-sharing protocols built into Microsoft Windows and + other popular PC operating systems, and supported on dozens of + other platforms, including UNIX. With CIFS, millions of computer + users can open and share remote files on the Internet without having + to install new software or change the way they work." + + + + If you consider CIFS as a backwardsly-compatible refinement of SMB + that will work reasonably efficiently over the Internet you won't be + too far wrong. + + The net effect is that Microsoft is now documenting large parts of + their Windows NT fileserver protocols. The security concepts embodied + in Windows NT are part of the specification, which is why Samba + documentation often talks in terms of Windows NT.

WWhhaatt iiss BBrroowwssiinngg?? + + The term "Browsing" causes a lot of confusion. It is the part of the + SMB/CIFS protocol which allows for resource discovery.

DDeessiiggnniinngg AA SSMMBB aanndd CCIIFFSS NNeettwwoorrkk + + + The big issues for installing any network of LAN or WAN file and print + servers are + + + +o How and where usernames, passwords and other security information + is stored + + +o What method can be used for locating the resources that users have + permission to use + + +o What protocols the clients can converse with + + + If you buy Netware, Windows NT or just about any other LAN fileserver + product you are expected to lock yourself into the product's preferred + answers to these questions. This tendancy is restrictive and often + very expensive for a site where there is only one kind of client or + server, and for sites with a mixture of operating systems it often + makes it impossible to share resources between some sets of users. + + The Samba philosophy is to make things as easy as possible for + administators, which means allowing as many combinations of clients, + servers, operating systems and protocols as possible. + + + 44..11.. WWoorrkkggrroouuppss,, DDoommaaiinnss,, AAuutthheennttiiccaattiioonn aanndd BBrroowwssiinngg + + + From the point of view of networking implementation, Domains and + Workgroups are _e_x_a_c_t_l_y the same, except for the client logon sequence. + Some kind of distributed authentication database is associated with a + domain (there are quite a few choices) and this adds so much + flexibility that many people think of a domain as a completely + different entity to a workgroup. From Samba's point of view a client + connecting to a service presents an authentication token, and it if it + is valid they have access.

However the network browsing functionality of domains + and workgroups is identical and is explained in <../BROWSING.txt>. + + There are some implementation differences: Windows 95 can be a member + of both a workgroup and a domain, but Windows NT cannot. Windows 95 + also has the concept of an "alternative workgroup". Samba can only be + a member of a single workgroup or domain, although this is due to + change with a future version when nmbd will be split into two daemons, + one for WINS and the other for browsing ( <../NetBIOS.txt> explains + what WINS is.) + + + 44..11..11..

The browsing database is + dynamic, modified as servers come and go on the network and as + resources are added or deleted. The term "browsing" refers to a + user accessing the database via whatever interface the client + provides, eg the OS/2 Workplace Shell or Windows 95 Explorer. + SMB servers agree between themselves as to which ones will + maintain the browsing database. Workgroups can be anywhere on a + connected TCP/IP network, including on different subnets or even + on the Interet. This is a very tricky part of SMB to implement. + + + MMaasstteerr BBrroowwsseerrss + are machines which holds the master browsing database for a + workgroup or domain. There are two kinds of Master Browser: + + + +o Domain Master Browser, which holds the master browsing + information for an entire domain, which may well cross multiple + TCP/IP subnets. + + +o Local Master Browser, which holds the master browsing database + for a particular subnet and communicates with the Domain Master + Browser to get information on other subnets. + + Subnets are differentiated because browsing is based on + broadcasts, and broadcasts do not pass through routers. Subnets + are not routed: while it is possible to have more than one + subnet on a single network segment this is regarded as very bad + practice. + + Master Browsers (both Domain and Local) are elected dynamically + according to an algorithm which is supposed to take into account + the machine's ability to sustain the browsing load. Samba can be + configured to always act as a master browser, ie it always wins + elections under all circumstances, even against systems such as + a Windows NT Primary Domain Controller which themselves expect + to win. + + There are also Backup Browsers which are promoted to Master + Browsers in the event of a Master Browser disappearing from the + network. + + Alternative terms include confusing variations such as "Browse + Master", and "Master Browser" which we are trying to eliminate + from the Samba documentation. + + + DDoommaaiinn CCoonnttrroolllleerr + is a term which comes from the Microsoft and IBM etc + implementation of the LAN Manager protocols.

Samba is typically +very stable and safe, and this is mostly due to the policy of many +public releases.</P> +<P>How the scheme works: +<OL> +<LI>When major changes are made the version number is increased. For +example, the transition from 1.9.15 to 1.9.16. However, this version +number will not appear immediately and people should continue to use +1.9.15 for production systems (see next point.) +</LI> +<LI>Just after major changes are made the software is considered +unstable, and a series of alpha releases are distributed, for example +1.9.16alpha1. These are for testing by those who know what they are +doing. The "alpha" in the filename will hopefully scare off those who +are just looking for the latest version to install. +</LI> +<LI>When Andrew thinks that the alphas have stabilised to the point +where he would recommend new users install it, he renames it to the +same version number without the alpha, for example 1.9.16. +</LI> +<LI>Inevitably bugs are found in the "stable" releases and minor patch +levels are released which give us the pXX series, for example 1.9.16p2.</LI> +</OL> + +So the progression goes: +<PRE> + 1.9.15p7 (production) + 1.9.15p8 (production) + 1.9.16alpha1 (test sites only) + : + 1.9.16alpha20 (test sites only) + 1.9.16 (production) + 1.9.16p1 (production) +</PRE> + +The above system means that whenever someone looks at the samba ftp +site they will be able to grab the highest numbered release without an +alpha in the name and be sure of getting the current recommended +version.</P> + + +<H2><A NAME="ss1.5">1.5 What platforms are supported? </A></H2> + +<P> +<A NAME="platforms"></A> + +Many different platforms have run Samba successfully.

It might be because you are using a uid +or gid of 65535 or -1. This is a VERY bad idea, and is a big security +hole. Check carefully in your /etc/passwd file and make sure that no +user has uid 65535 or -1. Especially check the "nobody" user, as many +broken systems are shipped with nobody setup with a uid of 65535.</P> +<P>It might also mean that your OS has a trapdoor uid/gid system :-)</P> +<P>This means that once a process changes effective uid from root to +another user it can't go back to root. Unfortunately Samba relies on +being able to change effective uid from root to non-root and back +again to implement its security policy. If your OS has a trapdoor uid +system this won't work, and several things in Samba may break. Less +things will break if you use user or server level security instead of +the default share level security, but you may still strike +problems.</P> +<P>The problems don't give rise to any security holes, so don't panic, +but it does mean some of Samba's capabilities will be unavailable. +In particular you will not be able to connect to the Samba server as +two different uids at once. This may happen if you try to print as a +"guest" while accessing a share as a normal user. It may also affect +your ability to list the available shares as this is normally done as +the guest user.</P> +<P>Complain to your OS vendor and ask them to fix their system.</P> +<P>Note: the reason why 65535 is a VERY bad choice of uid and gid is that +it casts to -1 as a uid, and the setreuid() system call ignores (with +no error) uid changes to -1. This means any daemon attempting to run +as uid 65535 will actually run as root.

Somewhere in your Win95 TCP/IP network +configuration (I'm too much of an NT bigot to know where it's located +in the Win95 setup, but I'll have to learn someday since I teach for a +Microsoft Solution Provider Authorized Tech Education Center - what an +acronym...) <F>Note: It's under Control Panel | Network | TCP/IP | WINS +Configuration</F> there's a little text entry field called something like +'Scope ID'.</P> +<P>This field essentially creates 'invisible' sub-workgroups on the same +wire.

If you, in fact, have +something in this box that EXACT value (case-sensitive!) needs to be +provided to smbclient and nmbd as the -i (lowercase) parameter.

There is also a generic Unix client program supplied as part +of the suite which allows Unix users to use an ftp-like interface to +access filespace and printers on any other SMB servers.

It might be because you are using a uid +or gid of 65535 or -1. This is a VERY bad idea, and is a big security +hole. Check carefully in your /etc/passwd file and make sure that no +user has uid 65535 or -1. Especially check the "nobody" user, as many +broken systems are shipped with nobody setup with a uid of 65535. + +It might also mean that your OS has a trapdoor uid/gid system :-) + +This means that once a process changes effective uid from root to +another user it can't go back to root. Unfortunately Samba relies on +being able to change effective uid from root to non-root and back +again to implement its security policy. If your OS has a trapdoor uid +system this won't work, and several things in Samba may break. Less +things will break if you use user or server level security instead of +the default share level security, but you may still strike +problems. + +The problems don't give rise to any security holes, so don't panic, +but it does mean some of Samba's capabilities will be unavailable. +In particular you will not be able to connect to the Samba server as +two different uids at once. This may happen if you try to print as a +"guest" while accessing a share as a normal user. It may also affect +your ability to list the available shares as this is normally done as +the guest user. + +Complain to your OS vendor and ask them to fix their system. + +Note: the reason why 65535 is a VERY bad choice of uid and gid is that +it casts to -1 as a uid, and the setreuid() system call ignores (with +no error) uid changes to -1.

The details of this depend on the + server OS, but typically you must edit a file whose name is + /etc/TIMEZONE or /etc/default/init, or run the command `zic -l'. + +<item>TZ must have the correct value. +<enum> + <item>If possible, use geographical time zone settings + (e.g. TZ='America/Los_Angeles' or perhaps + TZ=':US/Pacific'). These are supported by most + popular Unix OSes, are easier to get right, and are + more accurate for historical timestamps. If your + operating system has out-of-date tables, you should be + able to update them from the public domain time zone + tables at <url url="ftp://elsie.nci.nih.gov/pub/">. + + <item>If your system does not support geographical timezone + settings, you must use a Posix-style TZ strings, e.g. + TZ='PST8PDT,M4.1.0/2,M10.5.0/2' for US Pacific time. + Posix TZ strings can take the following form (with optional + items in brackets): +<verb> + StdOffset[Dst[Offset],Date/Time,Date/Time] +</verb> + where: +<itemize> +<item> `Std' is the standard time designation (e.g. `PST'). + +<item> `Offset' is the number of hours behind UTC (e.g. `8'). + Prepend a `-' if you are ahead of UTC, and + append `:30' if you are at a half-hour offset. + Omit all the remaining items if you do not use + daylight-saving time. + +<item> `Dst' is the daylight-saving time designation + (e.g. `PDT'). + + The optional second `Offset' is the number of + hours that daylight-saving time is behind UTC. + The default is 1 hour ahead of standard time. + +<item> `Date/Time,Date/Time' specify when daylight-saving + time starts and ends. The format for a date is + `Mm.n.d', which specifies the dth day (0 is Sunday) + of the nth week of the mth month, where week 5 means + the last such day in the month. The format for a + time is [h]h[:mm[:ss]], using a 24-hour clock. +</itemize> + Other Posix string formats are allowed but you don't want + to know about them. +</enum> +</enum> +On the client side, you must make sure that your client's clock and +time zone is also set appropriately. [[I don't know how to do this.]] +Samba traditionally has had many problems dealing with time zones, due +to the bizarre ways that Microsoft network protocols handle time +zones. A common symptom is for file timestamps to be off by an hour. +To work around the problem, try disconnecting from your Samba server +and then reconnecting to it; or upgrade your Samba server to +1.9.16alpha10 or later. + +<sect1> How do I set the printer driver name correctly? <p><label id="printer_driver_name"> +Question: + On NT, I opened "Printer Manager" and "Connect to Printer". + Enter ["\\ptdi270\ps1"] in the box of printer.

WWhhaatt iiss SSaammbbaa?? + + + Samba is a suite of programs which work together to allow clients to + access to a server's filespace and printers via the SMB (Server + Message Block) protocol. Initially written for Unix, Samba now also + runs on Netware, OS/2 and VMS. + + In practice, this means that you can redirect disks and printers to + Unix disks and printers from Lan Manager clients, Windows for + Workgroups 3.11 clients, Windows NT clients, Linux clients and OS/2 + clients. There is also a generic Unix client program supplied as part + of the suite which allows Unix users to use an ftp-like interface to + access filespace and printers on any other SMB servers. This gives the + capability for these operating systems to behave much like a LAN + Server or Windows NT Server machine, only with added functionality and + flexibility designed to make life easier for administrators. + + The components of the suite are (in summary): + + + +o ssmmbbdd, the SMB server. This handles actual connections from clients, + doing all the file, permission and username work + + +o nnmmbbdd, the Netbios name server, which helps clients locate servers, + doing the browsing work and managing domains as this capability is + being built into Samba + + + +o ssmmbbcclliieenntt, the Unix-hosted client program + + +o ssmmbbrruunn, a little 'glue' program to help the server run external + programs + + +o tteessttpprrnnss, a program to test server access to printers + + +o tteessttppaarrmmss, a program to test the Samba configuration file for + correctness + + +o ssmmbb..ccoonnff, the Samba configuration file + + +o ssmmbbpprriinntt, a sample script to allow a Unix host to use smbclient to + print to an SMB server + + +o DDooccuummeennttaattiioonn!! DON'T neglect to read it - you will save a great + deal of time! + + The suite is supplied with full source (of course!) and is GPLed. + + The primary creator of the Samba suite is Andrew Tridgell. Later + versions incorporate much effort by many net.helpers. The man pages + and this FAQ were originally written by Karl Auer. + + + 11..22.. WWhhaatt iiss tthhee ccuurrrreenntt vveerrssiioonn ooff SSaammbbaa?? + + + At time of writing, the current version was 1.9.17. If you want to be + sure check the bottom of the change-log file. + <ftp://samba.anu.edu.au/pub/samba/alpha/change-log> + + For more information see ``What do the version numbers mean?'' + + + 11..33.. WWhheerree ccaann II ggeett iitt?? + + + The Samba suite is available via anonymous ftp from samba.anu.edu.au. + The latest and greatest versions of the suite are in the directory: + + /pub/samba/ + + Development (read "alpha") versions, which are NOT necessarily stable + and which do NOT necessarily have accurate documentation, are + available in the directory: + + /pub/samba/alpha + + Note that binaries are NOT included in any of the above. Samba is + distributed ONLY in source form, though binaries may be available from + other sites. Recent versions of some Linux distributions, for example, + do contain Samba binaries for that platform. + + + 11..44.. WWhhaatt ddoo tthhee vveerrssiioonn nnuummbbeerrss mmeeaann?? + + + It is not recommended that you run a version of Samba with the word + "alpha" in its name unless you know what you are doing and are willing + to do some debugging. Many, many people just get the latest + recommended stable release version and are happy. If you are brave, by + all means take the plunge and help with the testing and development - + but don't install it on your departmental server. Samba is typically + very stable and safe, and this is mostly due to the policy of many + public releases. + How the scheme works: + + 1. When major changes are made the version number is increased. For + example, the transition from 1.9.15 to 1.9.16. However, this + version number will not appear immediately and people should + continue to use 1.9.15 for production systems (see next point.) + + 2. Just after major changes are made the software is considered + unstable, and a series of alpha releases are distributed, for + example 1.9.16alpha1. These are for testing by those who know what + they are doing. The "alpha" in the filename will hopefully scare + off those who are just looking for the latest version to install. + + 3. When Andrew thinks that the alphas have stabilised to the point + where he would recommend new users install it, he renames it to the + same version number without the alpha, for example 1.9.16. + + 4. Inevitably bugs are found in the "stable" releases and minor patch + levels are released which give us the pXX series, for example + 1.9.16p2. + + So the progression goes: + + 1.9.15p7 (production) + 1.9.15p8 (production) + 1.9.16alpha1 (test sites only) + : + 1.9.16alpha20 (test sites only) + 1.9.16 (production) + 1.9.16p1 (production) + + + The above system means that whenever someone looks at the samba ftp + site they will be able to grab the highest numbered release without an + alpha in the name and be sure of getting the current recommended ver- + sion. + + + 11..55..

It might be a good idea to scan the + archives of the mailing list, which are available through the Samba + web site described in the previous section. + + If you successfully solve a problem, please mail the FAQ maintainer a + succinct description of the symptom, the problem and the solution, so + I can incorporate it in the next version. + + If you make changes to the source code, _please_ submit these patches + so that everyone else gets the benefit of your work.

So on the server side, + there are two things to get right. + + 1. The Unix system clock must have the correct Universal time. Use + the shell command "sh -c 'TZ=UTC0 date'" to check this. + + 2. The TZ environment variable must be set on the server before Samba + is invoked. The details of this depend on the server OS, but + typically you must edit a file whose name is /etc/TIMEZONE or + /etc/default/init, or run the command `zic -l'. + + 3. TZ must have the correct value. + + a. If possible, use geographical time zone settings (e.g. + TZ='America/Los_Angeles' or perhaps TZ=':US/Pacific'). These + are supported by most popular Unix OSes, are easier to get + right, and are more accurate for historical timestamps. If your + operating system has out-of-date tables, you should be able to + update them from the public domain time zone tables at + <ftp://elsie.nci.nih.gov/pub/>. + + b. If your system does not support geographical timezone settings, + you must use a Posix-style TZ strings, e.g. + TZ='PST8PDT,M4.1.0/2,M10.5.0/2' for US Pacific time. Posix TZ + strings can take the following form (with optional items in + brackets): + + StdOffset[Dst[Offset],Date/Time,Date/Time] + + + where: + + +o `Std' is the standard time designation (e.g. `PST'). + + +o `Offset' is the number of hours behind UTC (e.g. `8'). Prepend + a `-' if you are ahead of UTC, and append `:30' if you are at a + half-hour offset. Omit all the remaining items if you do not + use daylight-saving time. + + +o `Dst' is the daylight-saving time designation (e.g. `PDT'). + + The optional second `Offset' is the number of hours that + daylight-saving time is behind UTC. The default is 1 hour ahead + of standard time. + + +o `Date/Time,Date/Time' specify when daylight-saving time starts + and ends. The format for a date is `Mm.n.d', which specifies + the dth day (0 is Sunday) of the nth week of the mth month, + where week 5 means the last such day in the month. The format + for a time is hh:mm[:ss], using a 24-hour clock. + + Other Posix string formats are allowed but you don't want to + know about them. + + On the client side, you must make sure that your client's clock and + time zone is also set appropriately. [I don't know how to do + this.] Samba traditionally has had many problems dealing with time + zones, due to the bizarre ways that Microsoft network protocols + handle time zones. A common symptom is for file timestamps to be + off by an hour.
