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): + +<itemize> +<item><bf>smbd</bf>, the SMB server. This handles actual connections from clients, doing all the file, permission and username work +<item><bf>nmbd</bf>, the Netbios name server, which helps clients locate servers, doing the browsing work and managing domains as this capability is being built into Samba +<item><bf>smbclient</bf>, the Unix-hosted client program +<item><bf>smbrun</bf>, a little 'glue' program to help the server run external programs +<item><bf>testprns</bf>, a program to test server access to printers +<item><bf>testparms</bf>, a program to test the Samba configuration file for correctness +<item><bf>smb.conf</bf>, the Samba configuration file +<item><bf>smbprint</bf>, a sample script to allow a Unix host to use smbclient to print to an SMB server +<item><bf>Documentation!</bf> DON'T neglect to read it - you will save a great deal of time! +</itemize> + +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. + +<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.org/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="where"> +The Samba suite is available via anonymous ftp from +samba.org. 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. + +<sect1> What do the version numbers mean? <p> <label id="version_nums"> +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: +<enum> +<item>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.) + +<item>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. + +<item>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. + +<item>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. +</enum> +So the progression goes: +<verb> + 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) +</verb> +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. + +<sect1> What platforms are supported? <p> <label id="platforms"> +Many different platforms have run Samba successfully. The platforms +most widely used and thus best tested are Linux and SunOS. + +At time of writing, the Makefile claimed support for: +<itemize> +<item> A/UX 3.0 +<item> AIX +<item> Altos Series 386/1000 +<item> Amiga +<item> Apollo Domain/OS sr10.3 +<item> BSDI +<item> B.O.S.

If +you have just installed Samba, have you run through the checklist in +<url url="ftp://samba.org/pub/samba/DIAGNOSIS.txt" name="DIAGNOSIS.txt">? It can save you a lot of time and effort. +DIAGNOSIS.txt can also be found in the docs directory of the Samba distribution. + +Secondly, read the man pages for smbd, nmbd and smb.conf, looking for +topics that relate to what you are trying to do. + +Thirdly, if there is no obvious solution to hand, try to get a look at +the log files for smbd and/or nmbd for the period during which you +were having problems. You may need to reconfigure the servers to +provide more extensive debugging information - usually level 2 or +level 3 provide ample debugging info. Inspect these logs closely, +looking particularly for the string "Error:". + +Fourthly, if you still haven't got anywhere, ask the mailing list or +newsgroup. In general nobody minds answering questions provided you +have followed the preceding steps. 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. This is one of +the most important aspects to the maintainence of Samba. Send all +patches to <htmlurl url="mailto:samba-patches@samba.org" name="samba-patches@samba.org">. Do not send patches to Andrew Tridgell or any +other individual, they may be lost if you do. + +<sect1> Pizza supply details <p> <label id="pizza"> +Those who have registered in the Samba survey as "Pizza Factory" will +already know this, but the rest may need some help. Andrew doesn't ask +for payment, but he does appreciate it when people give him +pizza. This calls for a little organisation when the pizza donor is +twenty thousand kilometres away, but it has been done. + +Method 1: Ring up your local branch of an international pizza chain +and see if they honour their vouchers internationally. Pizza Hut do, +which is how the entire Canberra Linux Users Group got to eat pizza +one night, courtesy of someone in the US + +Method 2: Ring up a local pizza shop in Canberra and quote a credit +card number for a certain amount, and tell them that Andrew will be +collecting it (don't forget to tell him.) One kind soul from Germany +did this. + +Method 3: Purchase a pizza voucher from your local pizza shop that has +no international affiliations and send it to Andrew. It is completely +useless but he can hang it on the wall next to the one he already has +from Germany :-) + +Method 4: Air freight him a pizza with your favourite regional +flavours. It will probably get stuck in customs or torn apart by +hungry sniffer dogs but it will have been a noble gesture. + +<sect>Compiling and installing Samba on a Unix host<p><label id="unix_install"> + +<sect1>I can't see the Samba server in any browse lists!<p><label id="no_browse"> + See <url url="ftp://samba.org/pub/samba/BROWSING.txt" name="BROWSING.txt"> + for more information on browsing. Browsing.txt can also be found + in the docs directory of the Samba source. + +If your GUI client does not permit you to select non-browsable +servers, you may need to do so on the command line. For example, under +Lan Manager you might connect to the above service as disk drive M: +thusly: +<tscreen><verb> + net use M: \\mary\fred +</verb></tscreen> +The details of how to do this and the specific syntax varies from +client to client - check your client's documentation. + +<sect1>Some files that I KNOW are on the server doesn't show up when I view the files from my client! <p> <label id="missing_files"> +See the next question. +<sect1>Some files on the server show up with really wierd filenames when I view the files from my client! <p> <label id="strange_filenames"> +If you check what files are not showing up, you will note that they +are files which contain upper case letters or which are otherwise not +DOS-compatible (ie, they are not legal DOS filenames for some reason). + +The Samba server can be configured either to ignore such files +completely, or to present them to the client in "mangled" form. If you +are not seeing the files at all, the Samba server has most likely been +configured to ignore them. Consult the man page smb.conf(5) for +details of how to change this - the parameter you need to set is +"mangled names = yes". + +<sect1>My client reports "cannot locate specified computer" or similar<p><label id="cant_see_server"> +This indicates one of three things: You supplied an incorrect server +name, the underlying TCP/IP layer is not working correctly, or the +name you specified cannot be resolved. + +After carefully checking that the name you typed is the name you +should have typed, try doing things like pinging a host or telnetting +to somewhere on your network to see if TCP/IP is functioning OK. 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 Lan 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). Assuming it +exists and you specified it correctly (read your client's docs on how +to specify a service name correctly), read on: + +<itemize> +<item> Many clients cannot accept or use service names longer than eight characters. +<item> Many clients cannot accept or use service names containing spaces. +<item> Some servers (not Samba though) are case sensitive with service names. +<item> Some clients force service names into upper case. +</itemize> + +<sect1>My client reports "cannot find domain controller", "cannot log on to the network" or similar <p> <label id="cant_see_net"> +Nothing is wrong - Samba does not implement the primary domain name +controller stuff for several reasons, including the fact that the +whole concept of a primary domain controller and "logging in to a +network" doesn't fit well with clients possibly running on multiuser +machines (such as users of smbclient under Unix). Having said that, +several developers are working hard on building it in to the next +major version of Samba. If you can contribute, send a message to +<htmlurl url="mailto:samba@samba.org" name="samba@samba.org"> ! + +Seeing this message should not affect your ability to mount redirected +disks and printers, which is really what all this is about. + +For many clients (including Windows for Workgroups and Lan Manager), +setting the domain to STANDALONE at least gets rid of the message. + +<sect1>Printing doesn't work :-(<p> <label id="no_printing"> +Make sure that the specified print command for the service you are +connecting to is correct and that it has a fully-qualified path (eg., +use "/usr/bin/lpr" rather than just "lpr"). + +Make sure that the spool directory specified for the service is +writable by the user connected to the service. In particular the user +"nobody" often has problems with printing, even if it worked with an +earlier version of Samba. Try creating another guest user other than +"nobody". + +Make sure that the user specified in the service is permitted to use +the printer. + +Check the debug log produced by smbd. 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. These should have all been solved. If not then please let Andrew +Tridgell know via email at <htmlurl url="mailto:samba@samba.org" name="samba@samba.org">. + +<sect1>My "server string" doesn't seem to be recognised<p><label id="bad_server_string"> +OR My client reports the default setting, eg. "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. Samba uses the +guest account for browsing in smbd. Check that your guest account is +valid. + +See also 'guest account' in smb.conf man page. + +<sect1>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. This is not good! + +<sect>Common client questions<p> <label id="client_questions"> + +<sect1>Are there any Macintosh clients for Samba?<p> <label id="mac_clients"> +Yes! Thursby now have a CIFS Client / Server called DAVE - see <url url="http://www.thursby.com/">. +They test it against Windows 95, Windows NT and samba for compatibility issues. +At the time of writing, DAVE was at version 1.0.1.

The problem comes when these users +use filemanager to mount shares from a Samba server. The most common +symptom is that the first user to connect get correct file permissions +and has a nice day, but subsequent connections get logged in as the +same user as the first person to login. They find that they cannot +access files in their own home directory, but that they can access +files in the first users home directory (maybe not such a nice day +after all?) + +Why does this happen? The above products all share a common heritage +(and code base I believe). They all open just a single TCP based SMB +connection to the Samba server, and requests from all users are piped +over this connection. This is unfortunate, but not fatal. + +It means that if you run your Samba server in share level security +(the default) then things will definately break as described +above. The share level SMB security model has no provision for +multiple user IDs on the one SMB connection. See <url url="ftp://samba.org/pub/samba/docs/security_level.txt" name="security_level.txt"> in +the docs for more info on share/user/server level security. + +If you run in user or server level security then you have a chance, +but only if you have a recent version of Samba (at least 1.9.15p6). In +older versions bugs in Samba meant you still would have had problems. + +If you have a trapdoor uid system in your OS then it will never work +properly. Samba needs to be able to switch uids on the connection and +it can't if your OS has a trapdoor uid system. You'll know this +because Samba will note it in your logs. + +Also note that you should not use the magic "homes" share name with +products like these, as otherwise all users will end up with the same +home directory. Use [\\server\username] instead. + +<sect1>Problem with printers under NT<p> <label id="nt_printers"> +This info from Stefan Hergeth +hergeth@f7axp1.informatik.fh-muenchen.de may be useful: + + A network-printer (with ethernetcard) is connected to the NT-Clients +via our UNIX-Fileserver (SAMBA-Server), like the configuration told by + Matthew Harrell harrell@leech.nrl.navy.mil (see WinNT.txt) +<enum> +<item>If a user has choosen this printer as the default printer in his + NT-Session and this printer is not connected to the network + (e.g. switched off) than this user has a problem with the SAMBA- + connection of his filesystems.
