Added faq directory under docs. Translated the whole of the current
FAQ into linuxdoc-sgml format. From now on we can change the file
sambafaq.sgml and then run sgml2txt and sgml2html to generate the
other files. (Home page for linuxdoc-sgml is
http://sunsite.unc.edu/mdw/Linuxdoc-SGML.html. Does cross references
and section management.)
(This used to be commit 2fedc53b4ea38e482fea7e3296637d6e44e031b7)

Initially written for Unix, Samba now also +runs on Netware, OS/2 and VMS.</P> +<P>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.</P> +<P>The components of the suite are (in summary):</P> +<P> +<UL> +<LI> smbd, the SMB server. This handles actual connections from +clients, doing all the file, permission and username work +</LI> +<LI>nmbd, the Netbios name server, which helps clients locate +servers, doing the browsing work and managing domains as this +capability is being built into Samba +</LI> +<LI>smbclient, the Unix-hosted client program +</LI> +<LI>smbrun, a little 'glue' program to help the server run external +programs +</LI> +<LI>testprns, a program to test server access to printers +</LI> +<LI>testparms, a program to test the Samba configuration file for +correctness +</LI> +<LI>smb.conf, the Samba configuration file +</LI> +<LI> smbprint, a sample script to allow a Unix host to use smbclient +to print to an SMB server +</LI> +<LI> documentation! DON'T neglect to read it - you will save a great +deal of time! +</LI> +</UL> +</P> +<P>The suite is supplied with full source (of course!) and is GPLed.</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="ss1.2">1.2 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 1.9.16. If you want to be +sure check the bottom of the change-log file. +<A HREF="ftp://samba.anu.edu.au/pub/samba/alpha/change-log">ftp://samba.anu.edu.au/pub/samba/alpha/change-log</A></P> +<P>For more information see +<A HREF="#version_nums">What do the version numbers mean?</A></P> + + +<H2><A NAME="ss1.3">1.3 Where can I get it? </A></H2> + +<P> +<A NAME="where"></A> +</P> +<P>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:</P> +<P>/pub/samba/</P> +<P>Development (read "alpha") versions, which are NOT necessarily stable +and which do NOT necessarily have accurate documentation, are +available in the directory:</P> +<P>/pub/samba/alpha</P> +<P>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.</P> + + +<H2><A NAME="ss1.4">1.4 What do the version numbers mean? </A></H2> + +<P> +<A NAME="version_nums"></A> +</P> +<P>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.</P> +<P>How the scheme works:</P> +<P>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.)</P> +<P>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.</P> +<P>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.</P> +<P>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.</P> +<P>So the progression goes:</P> +<P>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)</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="ss1.5">1.5 What platforms are supported? </A></H2> + +<P> +<A NAME="platforms"></A> +</P> +<P>Many different platforms have run Samba successfully. The platforms +most widely used and thus best tested are Linux and SunOS.</P> +<P>At time of writing, the Makefile claimed support for:</P> +<P>* SunOS +* Linux with shadow passwords +* Linux without shadow passwords +* SOLARIS +* SOLARIS 2.2 and above (aka SunOS 5) +* SVR4 +* ULTRIX +* OSF1 (alpha only) +* OSF1 with NIS and Fast Crypt (alpha only) +* OSF1 V2.0 Enhanced Security (alpha only) +* AIX +* BSDI +* NetBSD +* NetBSD 1.0 +* SEQUENT +* HP-UX +* SGI +* SGI IRIX 4.x.x +* SGI IRIX 5.x.x +* FreeBSD +* NeXT 3.2 and above +* NeXT OS 2.x +* NeXT OS 3.0 +* ISC SVR3V4 (POSIX mode) +* ISC SVR3V4 (iBCS2 mode) +* A/UX 3.0 +* SCO with shadow passwords. +* SCO with shadow passwords, without YP. +* SCO with TCB passwords +* SCO 3.2v2 (ODT 1.1) with TCP passwords +* intergraph +* DGUX +* Apollo Domain/OS sr10.3 (BSD4.3)</P> + + +<H2><A NAME="ss1.6">1.6 How can I find out more about Samba? </A></H2> + +<P> +<A NAME="more"></A> +</P> +<P>There are two mailing lists devoted to discussion of Samba-related +matters. There is also the newsgroup, comp.protocols.smb, which has a +great deal of discussion on Samba. There is also a WWW site 'SAMBA Web +Pages' at http://samba.canberra.edu.au/pub/samba/samba.html, under +which there is a comprehensive survey of Samba users. Another useful +resource is the hypertext archive of the Samba mailing list.</P> +<P>Send email to listproc@samba.anu.edu.au. Make sure the subject line is +blank, and include the following two lines in the body of the message:</P> +<P>subscribe samba Firstname Lastname +subscribe samba-announce Firstname Lastname</P> +<P>Obviously you should substitute YOUR first name for "Firstname" and +YOUR last name for "Lastname"! Try not to send any signature stuff, it +sometimes confuses the list processor.</P> +<P>The samba list is a digest list - every eight hours or so it +regurgitates a single message containing all the messages that have +been received by the list since the last time and sends a copy of this +message to all subscribers.</P> +<P>If you stop being interested in Samba, please send another email to +listproc@samba.anu.edu.au.

If +you have just installed Samba, have you run through the checklist in +DIAGNOSIS.txt? It can save you a lot of time and effort.</P> +<P>Secondly, read the man pages for smbd, nmbd and smb.conf, looking for +topics that relate to what you are trying to do.</P> +<P>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:".</P> +<P>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.</P> +<P>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.</P> +<P>If you make changes to the source code, _please_ submit these patches +so that everyone else gets the benefit of your work.

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.</P> +<P>Method 1: Ring up your local branch of an international pizza chain +and see if they honour their vouchers internationally.

One kind soul from Germany +did this.</P> +<P>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 :-)</P> +<P>Method 4: Air freight him a pizza with your favourite regional +flavours.

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.</P> +<P>In earlier Samba versions there were some difficulties with the very +latest Microsoft products, particularly Excel 5 and Word for Windows +6.

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. This is not good!</P> + + +<HR> +<A HREF="sambafaq-1.html">Previous</A> +<A HREF="sambafaq-3.html">Next</A> +<A HREF="sambafaq.html#toc2">Table of Contents</A> +</BODY> +</HTML> diff --git a/docs/faq/sambafaq-3.html b/docs/faq/sambafaq-3.html new file mode 100644 index 0000000000..01401017b9 --- /dev/null +++ b/docs/faq/sambafaq-3.html @@ -0,0 +1,275 @@ +<HTML> +<HEAD> +<TITLE> Samba FAQ: Common client questions</TITLE> +</HEAD> +<BODY> +<A HREF="sambafaq-2.html">Previous</A> +<A HREF="sambafaq-4.html">Next</A> +<A HREF="sambafaq.html#toc3">Table of Contents</A> +<HR> +<H2><A NAME="s3">3.

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.

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> smbd, the SMB server.

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 1.9.16. 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="where"> + +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. + +<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: + +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 +version. + +<sect1> What platforms are supported? <p> <label id="platforms"> + +Many different platforms have run Samba successfully.

If +you have just installed Samba, have you run through the checklist in +DIAGNOSIS.txt? It can save you a lot of time and effort. + +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.

If you +are not seeing the files at all, the Samba server has most likely been +configured to ignore them.

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.

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.

The Macintosh has ALWAYS spoken Appletalk. Even with +Microsoft "services for Macintosh", it has been a matter of making the +server speak Appletalk. It is the same for Novell Netware and the +Macintosh, although I believe Novell has (VERY LATE) released an +extension for the Mac to let it speak IPX. + +In future Apple System Software, you may see support for other +protocols, such as SMB -- Applet is working on a new networking +architecture that will --> -- make it easier to support additional +protocols. But it's not here yet. + +Now, the nice part is that if you want your Unix machine to speak +Appletalk, there are several options. "Netatalk" and "CAP" are free, +and available on the net. There are also several commercial options, +such as "PacerShare" and "Helios" (I think). In any case, you'll have +to look around for a server, not anything for the Mac. + +Depending on you OS, some of these may not help you.

The logging options (-d3 or greater) can help a lot with that. +DNS and WINS configuration can also impact connectivity as well. + +Now, on to 'scope id's. 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...)

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 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.

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.

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. + + 3a. 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:ftp://elsie.nci.nih.gov/pub/. + + 3b. If your system does not support geographical time +zone + 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: + + `Std' is the standard time designation +(e.g. `PST'). + + `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. + + `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. + + `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. + + 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. +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.

General Information + + All about Samba - what it is, how to get it, related sources of + information, how to understand the version numbering scheme, pizza + details + + 1.1. What is Samba? + + 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 smbd, the SMB server. This handles actual connections from clients, + doing all the file, permission and username work + + o nmbd, 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 smbclient, the Unix-hosted client program + + o smbrun, a little 'glue' program to help the server run external + programs + + o testprns, a program to test server access to printers + + o testparms, a program to test the Samba configuration file for + correctness + + o smb.conf, the Samba configuration file + + o smbprint, a sample script to allow a Unix host to use smbclient to + print to an SMB server + + o documentation! 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. + + 1.2. What is the current version of Samba? + + At time of writing, the current version was 1.9.16. 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?'' + + 1.3. Where can I get it? + + 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. + + 1.4. What do the version numbers mean? + + 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 + version. + + 1.5. What platforms are supported? + + 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: + + * SunOS * Linux with shadow passwords * Linux without shadow passwords + * SOLARIS * SOLARIS 2.2 and above (aka SunOS 5) * SVR4 * ULTRIX * OSF1 + (alpha only) * OSF1 with NIS and Fast Crypt (alpha only) * OSF1 V2.0 + Enhanced Security (alpha only) * AIX * BSDI * NetBSD * NetBSD 1.0 * + SEQUENT * HP-UX * SGI * SGI IRIX 4.x.x * SGI IRIX 5.x.x * FreeBSD * + NeXT 3.2 and above * NeXT OS 2.x * NeXT OS 3.0 * ISC SVR3V4 (POSIX + mode) * ISC SVR3V4 (iBCS2 mode) * A/UX 3.0 * SCO with shadow + passwords. * SCO with shadow passwords, without YP. * SCO with TCB + passwords * SCO 3.2v2 (ODT 1.1) with TCP passwords * intergraph * DGUX + * Apollo Domain/OS sr10.3 (BSD4.3) + + 1.6. How can I find out more about Samba? + + There are two mailing lists devoted to discussion of Samba-related + matters. There is also the newsgroup, comp.protocols.smb, which has a + great deal of discussion on Samba. There is also a WWW site 'SAMBA Web + Pages' at http://samba.canberra.edu.au/pub/samba/samba.html, under + which there is a comprehensive survey of Samba users. Another useful + resource is the hypertext archive of the Samba mailing list. + + Send email to listproc@samba.anu.edu.au. Make sure the subject line is + blank, and include the following two lines in the body of the message: + + subscribe samba Firstname Lastname subscribe samba-announce Firstname + Lastname + + Obviously you should substitute YOUR first name for "Firstname" and + YOUR last name for "Lastname"! Try not to send any signature stuff, it + sometimes confuses the list processor. + + The samba list is a digest list - every eight hours or so it + regurgitates a single message containing all the messages that have + been received by the list since the last time and sends a copy of this + message to all subscribers. + + If you stop being interested in Samba, please send another email to + listproc@samba.anu.edu.au. Make sure the subject line is blank, and + include the following two lines in the body of the message: + + unsubscribe samba unsubscribe samba-announce + + The From: line in your message MUST be the same address you used when + you subscribed. + + 1.7. Something's gone wrong - what should I do? + + # *** IMPORTANT! *** # DO NOT post messages on mailing lists or in + newsgroups until you have carried out the first three steps given + here! + + Firstly, see if there are any likely looking entries in this FAQ! If + you have just installed Samba, have you run through the checklist in + DIAGNOSIS.txt? It can save you a lot of time and effort. + + 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 samba-bugs@samba.anu.edu.au, not Andrew Tridgell or any + other individual and not the samba team mailing list. + + 1.8. Pizza supply details + + 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. + + 2. Compiling and installing Samba on a Unix host + + 2.1. I can't see the Samba server in any browse lists! + + *** Until the FAQ can be updated, please check the file: *** + ftp://samba.anu.edu.au/pub/samba/BROWSING.txt *** for more information + on browsing. + + 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: + + net use M: \maryed + + The details of how to do this and the specific syntax varies from + client to client - check your client's documentation. + + 2.2. view the files from my client! Some files that I KNOW are on + the server doesn't show up when I + + 2.3. I view the files from my client! Some files on the server show + up with really wierd filenames when + + 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". + + 2.4. My client reports "cannot locate specified computer" or similar + + 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 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 :-) + + 2.5. similar My client reports "cannot locate specified share name" + or + + 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).

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 + samba-bugs! + + 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. + + 2.7. Printing doesn't work :-( + + 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. + + 2.8. My programs install on the server OK, but refuse to work prop- + erly + + 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. + + 2.9. My "server string" doesn't seem to be recognised + + 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. In a future + version these will probably be combined and -C will be removed, but + for now use -C + + 2.10. resources" My client reports "This server is not configured to + list shared + + 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. + + 2.11. Log message "you appear to have a trapdoor uid system" + + 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! + + 3. Common client questions + + 3.1. Are any Macintosh clients for Samba + + In Rob Newberry's words (rob@eats.com, Sun, 4 Dec 1994): + + The answer is "No." Samba speaks SMB, the protocol used for Microsoft + networks. The Macintosh has ALWAYS spoken Appletalk. Even with + Microsoft "services for Macintosh", it has been a matter of making the + server speak Appletalk. It is the same for Novell Netware and the + Macintosh, although I believe Novell has (VERY LATE) released an + extension for the Mac to let it speak IPX. + + In future Apple System Software, you may see support for other + protocols, such as SMB -- Applet is working on a new networking + architecture that will --> -- make it easier to support additional + protocols. But it's not here yet. + + Now, the nice part is that if you want your Unix machine to speak + Appletalk, there are several options. "Netatalk" and "CAP" are free, + and available on the net. There are also several commercial options, + such as "PacerShare" and "Helios" (I think). In any case, you'll have + to look around for a server, not anything for the Mac. + + Depending on you OS, some of these may not help you. I am currently + coordinating the effort to get CAP working with Native Ethertalk under + Linux, but we're not done yet. + + 3.2. Session request failed (131,130)" error + + The following answer is provided by John E. Miller: + + I'll assume that you're able to ping back and forth between the + machines by IP address and name, and that you're using some security + model where you're confident that you've got user IDs and passwords + right. The logging options (-d3 or greater) can help a lot with that. + DNS and WINS configuration can also impact connectivity as well. + + Now, on to 'scope id's. 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...) Note: It's under Control Panel | Network | TCP/IP | WINS + Configuration there's a little text entry field called something like + + This field essentially creates 'invisible' sub-workgroups on the same + wire. Boxes can only see other boxes whose Scope IDs are set to the + exact same value - it's sometimes used by OEMs to configure their + boxes to browse only other boxes from the same vendor and, in most + environments, this field should be left blank. 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. So, if + your Scope ID is configured as the string 'SomeStr' in Win95 then + you'd have to use smbclient -iSomeStr otherparms in connecting to it. + + 3.3. How do I synchronise my PC's clock with my Samba server? + + To syncronize your PC's clock with your Samba server: + + * Copy timesync.pif to your windows directory * timesync.pif can be + found at: + http://samba.canberra.edu.au/pub/samba/binaries/miscellaneous/timesync.pif + * Add timesync.pif to your 'Start Up' group/folder * Open the + properties dialog box for the program/icon * Make sure the 'Run + Minimized' option is set in program * Change the command line section + that reads \sambahost to reflect the name of your server. * Close the + properties dialog box by choosing 'OK' + + Each time you start your computer (or login for Win95) your PC will + synchronize it's clock with your Samba server. + + 3.4. Problems with WinDD, NTrigue, WinCenterPro etc + + All of the above programs are applications that sit on an NT box and + allow multiple users to access the NT GUI applications from remote + workstations (often over X). + + What has this got to do with Samba? 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 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 \serversername instead. + + 3.5. Problem with printers under NT + + 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) + + 1.) 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. It's very slow. + + 2.) If the printer is connected to the network everything works fine. + + 3.) When the smbd ist started with debug level 3, you can see that the + NT spooling system try to connect to the printer many times. If the + printer ist not connected to the network this request fails and the NT + spooler is wasting a lot of time to connect to the printer service. + This seems to be the reason for the slow network connection. + + 4.) Maybe it's possible to change this behaviour by setting different + printer properties in the Print-Manager-Menu of NT, but i didn't try + it yet. + + 3.6. Why are my file's timestamps off by an hour, or by a few hours? + + This is from Paul Eggert eggert@twinsun.com. + + Most likely it's a problem with your time zone settings. + + Internally, Samba maintains time in traditional Unix format, namely, + the number of seconds since 1970-01-01 00:00:00 Universal Time (or + ``GMT''), not counting leap seconds. + + On the server side, Samba uses the Unix TZ variable to convert + internal timestamps to and from local time. 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. + + 3a. 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:ftp://elsie.nci.nih.gov/pub/. + + 3b. If your system does not support geographical time zone 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): + + StdOffsetDst[Offset,Date/Time,Date/Time] + + where: + + `Std' is the standard time designation (e.g. `PST'). + + `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. + + `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. + `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. + 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. + + 3.7. How do I set the printer driver name correctly? + + Question: > On NT, I opened "Printer Manager" and "Connect to + Printer". > Enter "\ptdi270s1" + in the box of printer. I got the > following error message: > > + You do not have sufficient access to your machine > to connect to + the selected printer, since a driver > needs to be installed + locally. + + Answer: + + In the more recent versions of Samba you can now set the "printer + driver" in smb.conf. This tells the client what driver to use. For + example, I have: + + printer driver = HP LaserJet 4L + + and NT knows to use the right driver. You have to get this string + exactly right. + + To find the exact string to use, you need to get to the dialog box in + your client where you select which printer driver to install. The + correct strings for all the different printers are shown in a listbox + in that dialog box. + + You could also try setting the driver to NULL like this: + + printer driver = NULL + + this is effectively what older versions of Samba did, so if that + worked for you then give it a go. If this does work then let me know + and I'll make it the default. Currently the default is a 0 length + string. + + 4. Specific client application problems + + 4.1.
