                                    about the

                                   SAMBA Suite

                  (FAQ version 1.9.15a, Samba version 1.09.15)

-------------------------------------------------------------------------------

This FAQ was originally prepared by Karl Auer and is
currently maintained by Paul Blackman (ictinus@lake.canberra.edu.au).

As Karl originally said, 'this FAQ was prepared with lots of help from numerous
net.helpers', and that's the way I'd like to keep it. So if you find anything
that you think should be in here don't hesitate to contact me.

Thanks to Karl for the work he's done, and continuing thanks to Andrew Tridgell
for developing Samba.

Note: This FAQ is (and probably always will be) under construction. Some
sections exist only as optimistic entries in the Contents page.

===============================================================================
SECTION ONE: General information
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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 (Session Message Block) 
protocol. Initially written for Unix, Samba now also runs on Netware, OS/2 and
AmigaDOS.

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):

     * smbd, the SMB server. This handles actual connections from clients,
         doing all the file, permission and username work
     * 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
     * smbclient, the Unix-hosted client program
     * smbrun, a little 'glue' program to help the server run external
         programs
     * testprns, a program to test server access to printers
     * testparms, a program to test the Samba configuration file for
         correctness
     * smb.conf, the Samba configuration file
     * smbprint, a sample script to allow a Unix host to use smbclient to
         print to an SMB server
     * 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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 question 5, "What do the version numbers mean?"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 5: 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 4: 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.

     * intergraph
     * DGUX
     * Apollo Domain/OS sr10.3 (BSD4.3)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 5: 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 6: 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.

* n: 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.

===============================================================================
SECTION TWO: Compiling and installing Samba on a Unix host
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


===============================================================================
SECTION THREE: Common client problems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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/docs/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: \\mary\fred

The details of how to do this and the specific syntax varies from client to
client - check your client's documentation.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 2: Some files that I KNOW are on the server doesn't show up when I view the
     directories from my client!

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".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 3: Some files on the server show up with really wierd filenames when I view
the directories from my client!

If you check what files are showing up wierd, 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 seeing strange file
names, they are most likely "mangled". If you would prefer to have such files
ignored rather than presented in "mangled" form, consult the man page
smb.conf(5) for details of how to change the server configuration - the
parameter you need to set is "mangled names = no".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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 :-)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 5: My client reports "cannot locate specified share name" or similar.

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 doco on how to specify a service
name correctly), read on:

     * Many clients cannot accept or use service names longer than eight
         characters.
     * Many clients cannot accept or use service names containing spaces.
     * Some servers (not Samba though) are case sensitive with service names.
     * Some clients force service names into upper case.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 6: My client reports "cannot find domain controller", "cannot log on to the
network" or similar.

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 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 8: My programs install on the server OK, but refuse to work properly.

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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 9: My "server string" doesn't seem to be recognized, 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

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 10: When I attempt to get a listing of available resources from the Samba
      server, my client reports
      "This server is not configured to list shared resources".

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.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 11: You get the message "you appear to have a trapdoor uid system"
      in your logs

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!

===============================================================================
SECTION FOUR: Specific client problems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 1: Are any MacIntosh clients for Samba.

Yes. Thursby Software Systems have released 'Dave' - a SMB client for
MacIntosh systems. This is a commercial product and inclusion in this
faq does not imply any endorsement by the Samba developers. Having said
that, the first public demonstration of 'Dave' was to the Samba server
run by Andrew Tridgell over the Internet from Redmond, Washington, USA to
Australia as part of the first CIFS developers conference.

For more details on 'Dave' contact :

There are currently no Free Software solutions other than to make
your UNIX server talk AppleTalk.

In Rob Newberry's words (rob@eats.com, Sun, 4 Dec 1994):

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.

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 your 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.

* 2: I am getting a "Session request failed (131,130)" error when I try to
     connect to my Win95 PC with smbclient. I am able to connect from the PC
     to the Samba server without problems. What gives?

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 'Scope ID'. 

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: How do I synchronize 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 'Properties' 
  * 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.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 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 \\server\username instead.

* 5: Problem with printers under NT

This info from Stefan Hergeth 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.

 I hope this information will help in some way.

* 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):

                        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.

* 7: How do I set the printer driver name correctly?

Question:
> On NT, I opened "Printer Manager" and "Connect to Printer". 
> Enter "\\ptdi270\ps1" 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.

* 8: I have upgraded my NT 4.0 system to service pack 3. Why
     can't I connect anymore ?

This is not a bug.  Microsoft has changed their policy on sending
unencrypted passwords over the net.  They no longer default to allowing
unencrypted passwords to be sent over the net.  This effects all Samba
servers which are configured to use security=share or security=user level
security without password encryption. They do, however, have a fix which 
can be applied to the registry to fix the problem.  Here's a synopsis 
from the SP3 web page that discusses how to enable unencrypted password 
sending from an NT 4.0 box.

A better solution is to re-compile Samba to use encrypted passwords.
See the document :

ftp://samba.anu.edu.au/pub/samba/docs/ENCRYPTION.txt

* 1: MS Office Setup reports "Cannot change properties of the file named:
                                      X:\MSOFFICE\SETUP.INI"

When installing MS Office on a Samba drive for which you have admin user
permissions, ie. admin users = <username>, you will find the setup program
unable to complete the installation.

To get around this problem, do the installation without admin user permissions
The problem is that MS Office Setup checks that a file is rdonly by trying to
open it for writing.

Admin users can always open a file for writing, as they run as root. 
You just have to install as a non-admin user and then use "chown -R" to fix
the owner.
