MS Windows network -administrators are often confused regarding network access controls and what is the best way to -provide users with the type of access they need while protecting resources from the consequences -of untoward access capabilities. -</p><p> -Unix administrators frequently are not familiar with the MS Windows environment and in particular -have difficulty in visualizing what the MS Windows user wishes to achieve in attempts to set file -and directory access permissions. -</p><p> -The problem lies in the differences in how file and directory permissions and controls work -between the two environments. This difference is one that Samba can not completely hide, even -though it does try to make the chasm transparent. -</p><p> -POSIX Access Control List technology has been available (along with Extended Attributes) -for Unix for many years, yet there is little evidence today of any significant use. This -explains to some extent the slow adoption of ACLs into commercial Linux products. MS Windows -administrators are astounded at this given that ACLs were a foundational capability of the now -decade old MS Windows NT operating system. -</p><p> -The purpose of this chapter is to present each of the points of control that are possible with -Samba-3 in the hope that this will help the network administrator to find the optimum method -for delivering the best environment for MS Windows desktop users. -</p><p> -This is an opportune point to mention that it should be borne in mind that Samba was created to -provide a means of interoperability and interchange of data between two operating environments -that are quite different. It was never the intent to make Unix/Linux like MS Windows NT. Instead -the purpose was an is to provide a sufficient level of exchange of data between the two environments. -What is available today extends well beyond early plans and expectations, yet the gap continues to -shrink. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2920239"></a>Features and Benefits</h2></div></div><div></div></div><p> - Samba offers a lot of flexibility in file system access management. These are the key access control - facilities present in Samba today: - </p><div class="itemizedlist"><p class="title"><b>Samba Access Control Facilities</b></p><ul type="disc"><li><p> - <span class="emphasis"><em>Unix File and Directory Permissions</em></span> - </p><p> - Samba honours and implements Unix file system access controls. Users - who access a Samba server will do so as a particular MS Windows user. - This information is passed to the Samba server as part of the logon or - connection setup process. Samba uses this user identity to validate - whether or not the user should be given access to file system resources - (files and directories). This chapter provides an overview for those - to whom the Unix permissions and controls are a little strange or unknown. - </p></li><li><p> - <span class="emphasis"><em>Samba Share Definitions</em></span> - </p><p> - In configuring share settings and controls in the <tt class="filename">smb.conf</tt> file - the network administrator can exercise over-rides to native file - system permissions and behaviours. This can be handy and convenient - to affect behaviour that is more like what MS Windows NT users expect - but it is seldom the <span class="emphasis"><em>best</em></span> way to achieve this. - The basic options and techniques are described herein. - </p></li><li><p> - <span class="emphasis"><em>Samba Share ACLs</em></span> - </p><p> - Just like it is possible in MS Windows NT to set ACLs on shares - themselves, so it is possible to do this in Samba. - Very few people make use of this facility, yet it remains on of the - easiest ways to affect access controls (restrictions) and can often - do so with minimum invasiveness compared with other methods. - </p></li><li><p> - <span class="emphasis"><em>MS Windows ACLs through Unix POSIX ACLs</em></span> - </p><p> - The use of POSIX ACLs on Unix/Linux is possible ONLY if the underlying - operating system supports them. If not, then this option will not be - available to you. Current Unix technology platforms have native support - for POSIX ACLs. There are patches for the Linux kernel that provide - this also. Sadly, few Linux platforms ship today with native ACLs and - Extended Attributes enabled. This chapter has pertinent information - for users of platforms that support them. - </p></li></ul></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2920364"></a>File System Access Controls</h2></div></div><div></div></div><p> -Perhaps the most important recognition to be made is the simple fact that MS Windows NT4 / 200x / XP -implement a totally divergent file system technology from what is provided in the Unix operating system -environment. Firstly we should consider what the most significant differences are, then we shall look -at how Samba helps to bridge the differences. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2920382"></a>MS Windows NTFS Comparison with Unix File Systems</h3></div></div><div></div></div><p> - Samba operates on top of the Unix file system. This means it is subject to Unix file system conventions - and permissions. It also means that if the MS Windows networking environment requires file system - behaviour that differs from unix file system behaviour then somehow Samba is responsible for emulating - that in a transparent and consistent manner. - </p><p> - It is good news that Samba does this to a very large extent and on top of that provides a high degree - of optional configuration to over-ride the default behaviour. We will look at some of these over-rides, - but for the greater part we will stay within the bounds of default behaviour. Those wishing to explore - to depths of control ability should review the <tt class="filename">smb.conf</tt> man page. - </p><div class="variablelist"><p class="title"><b>File System Feature Comparison</b></p><dl><dt><span class="term">Name Space</span></dt><dd><p> - MS Windows NT4 / 200x/ XP files names may be up to 254 characters long, Unix file names - may be 1023 characters long. In MS Windows file extensions indicate particular file types, - in Unix this is not so rigorously observed as all names are considered arbitrary. - </p><p> - What MS Windows calls a Folder, Unix calls a directory, - </p></dd><dt><span class="term">Case Sensitivity</span></dt><dd><p> - MS Windows file names are generally Upper Case if made up of 8.3 (ie: 8 character file name - and 3 character extension. If longer than 8.3 file names are Case Preserving, and Case - Insensitive. - </p><p> - Unix file and directory names are Case Sensitive and Case Preserving. Samba implements the - MS Windows file name behaviour, but it does so as a user application. The Unix file system - provides no mechanism to perform case insensitive file name lookups. MS Windows does this - by default. This means that Samba has to carry the processing overhead to provide features - that are NOT native to the Unix operating system environment. - </p><p> - Consider the following, all are unique Unix names but one single MS Windows file name: - <tt class="computeroutput"> - MYFILE.TXT - MyFile.txt - myfile.txt - </tt> - So clearly, In an MS Windows file name space these three files CAN NOT co-exist! But in Unix - they can. So what should Samba do if all three are present? Answer, the one that is lexically - first will be accessible to MS Windows users, the others are invisible and unaccessible - any - other solution would be suicidal. - </p></dd><dt><span class="term">Directory Separators</span></dt><dd><p> - MS Windows and DOS uses the back-slash '\' as a directory delimiter, Unix uses the forward-slash '/' - as it's directory delimiter. This is transparently handled by Samba. - </p></dd><dt><span class="term">Drive Identification</span></dt><dd><p> - MS Windows products support a notion of drive letters, like <b class="command">C:</b> to represent - disk partitions. Unix has NO concept if separate identifiers for file partitions since each - such file system is <tt class="filename">mounted</tt> to become part of the over-all directory tree. - The Unix directory tree begins at '/', just like the root of a DOS drive is specified like - <b class="command">C:\</b>. - </p></dd><dt><span class="term">File Naming Conventions</span></dt><dd><p> - MS Windows generally never experiences file names that begin with a '.', while in Unix these - are commonly found in a user's home directory. Files that begin with a '.' are typically - either start up files for various Unix applications, or they may be files that contain - start-up configuration data. - </p></dd><dt><span class="term">Links and Short-Cuts</span></dt><dd><p> - MS Windows make use of "links and Short-Cuts" that are actually special types of files that will - redirect an attempt to execute the file to the real location of the file. Unix knows of file and directory - links, but they are entirely different from what MS Windows users are used to. - </p><p> - Symbolic links are files in Unix that contain the actual location of the data (file OR directory). An - operation (like read or write) will operate directly on the file referenced. Symbolic links are also - referred to as 'soft links'. A hard link is something that MS Windows is NOT familiar with. It allows - one physical file to be known simultaneously by more than one file name. - </p></dd></dl></div><p> - There are many other subtle differences that may cause the MS Windows administrator some temporary discomfort - in the process of becoming familiar with Unix/Linux. These are best left for a text that is dedicated to the - purpose of Unix/Linux training/education. - </p></div><div xmlns:ns30="" class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2917299"></a>Managing Directories</h3></div></div><div></div></div><ns30:p> - There are three basic operations for managing directories, <b class="command">create, delete, rename</b>. - </ns30:p><div class="table"><a name="id2917317"></a><p class="title"><b>Table 13.1.

This means that you can only - manipulate the current user/group/world permissions listed in - the dialog box. This actually works quite well as these are the - only permissions that UNIX actually has.</p><p>If a permission triplet (either user, group, or world) - is removed from the list of permissions in the NT dialog box, - then when the <span class="guibutton">OK</span> button is pressed it will - be applied as "no permissions" on the UNIX side.

From inside that (remote X) - session I started a rdesktop session on another, a Windows XP machine. - To test the performance, I played Pinball. I am proud to announce here - that my score was 631750 points at first try... - </p><p> - NX performs better on my local LAN than any of the other "pure" - connection methods I am using from time to time: TightVNC, rdesktop or - remote X. It is even faster than a direct crosslink connection between - two nodes. - </p><p> - I even got sound playing from the remote X app to my local boxes, and - had a working "copy'n'paste" from an NX window (running a KDE session - in Italy) to my Mozilla mailing agent... These guys are certainly doing - something right! - </p><p> - I recommend to test drive NX to anybody with a only a remote interest - in remote computing - <a href="http://www.nomachine.com/testdrive.php" target="_top">http://www.nomachine.com/testdrive.php</a>. - </p><p> - Just download the free of charge client software (available for RedHat, - SuSE, Debian and Windows) and be up and running within 5 minutes (they - need to send you your account data, though, because you are assigned - a real Unix account on their testdrive.nomachine.com box... - </p><p> - They plan to get to the point were you can have NX application servers - running as a cluster of nodes, and users simply start an NX session locally, - and can select applications to run transparently (apps may even run on - another NX node, but pretend to be on the same as used for initial login, - because it displays in the same window.... well, you also can run it - fullscreen, and after a short time you forget that it is a remote session - at all). - </p><p> - Now the best thing at the end: all the core compression and caching - technologies are released under the GPL and available as source code - to anybody who wants to build on it! These technologies are working, - albeit started from the command line only (and very inconvenient to - use in order to get a fully running remote X session up and running....) - </p><p> - To answer your questions: - </p><div class="itemizedlist"><ul type="disc"><li><p> - You don't need to install a terminal server; XP has RDP support built in. - </p></li><li><p> - NX is much cheaper than Citrix -- and comparable in performance, probably faster - </p></li><li><p> - You don't need to hack XP -- it just works - </p></li><li><p> - You log into the XP box from remote transparently (and I think there is no - need to change anything to get a connection, even if authentication is against a domain) - </p></li><li><p> - The NX core technologies are all Open Source and released under the GPL -- - you can today use a (very inconvenient) commandline to use it at no cost, - but you can buy a comfortable (proprietary) NX GUI frontend for money - </p></li><li><p> - NoMachine are encouraging and offering help to OSS/Free Software implementations - for such a frontend too, even if it means competition to them (they have written - to this effect even to the LTSP, KDE and GNOME developer mailing lists) - </p></li></ul></div></div></div><div xmlns:ns79="" class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2981560"></a>Network Logon Script Magic</h2></div></div><div></div></div><p> -This section needs work.

target="_top">CUPS</a>) has become very popular. All - big Linux distributions now ship it as their default printing - system. But to many it is still a very mystical tool. Normally it - "just works" (TM). People tend to regard it as a sort of "black box", - which they don't want to look into, as long as it works OK. But once - there is a little problem, they are in trouble to find out where to - start debugging it. Also, even the most recent and otherwise excellent - printed Samba documentation has only limited attention paid to CUPS - printing, leaving out important pieces or even writing plain wrong - things about it. This demands rectification. But before you dive into - this chapter, make sure that you don't forget to refer to the - "Classical Printing" chapter also. It contains a lot of information - that is relevant for CUPS too. - </p><p> - CUPS sports quite a few unique and powerful features. While their - basic functions may be grasped quite easily, they are also - new. Because they are different from other, more traditional printing - systems, it is best to try and not apply any prior knowledge about - printing upon this new system. Rather try to start understand CUPS - from the beginning. This documentation will lead you here to a - complete understanding of CUPS, if you study all of the material - contained. But lets start with the most basic things first. Maybe this - is all you need for now. Then you can skip most of the other - paragraphs. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2957352"></a>Overview</h3></div></div><div></div></div><p> - CUPS is more than just a print spooling system. It is a complete - printer management system that complies with the new IPP - (<span class="emphasis"><em>Internet Printing Protocol</em></span>). IPP is an industry - and IETF (<span class="emphasis"><em>Internet Engineering Task Force</em></span>) - standard for network printing. Many of its functions can be managed - remotely (or locally) via a web browser (giving you a - platform-independent access to the CUPS print server). In addition it - has the traditional commandline and several more modern GUI interfaces - (GUI interfaces developed by 3rd parties, like KDE's - overwhelming <a href="http://printing.kde.org/" target="_top">KDEPrint</a>). - </p><p> - CUPS allows creation of "raw" printers (ie: NO print file - format translation) as well as "smart" printers (i.e. CUPS does - file format conversion as required for the printer). In many ways - this gives CUPS similar capabilities to the MS Windows print - monitoring system. Of course, if you are a CUPS advocate, you would - argue that CUPS is better! In any case, let us now move on to - explore how one may configure CUPS for interfacing with MS Windows - print clients via Samba. - </p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2957404"></a>Basic Configuration of CUPS support</h2></div></div><div></div></div><p> - Printing with CUPS in the most basic <tt class="filename">smb.conf</tt> - setup in Samba 3.0 (as was true for 2.2.x) only needs two - settings: <i class="parameter"><tt>printing = cups</tt></i> and <i class="parameter"><tt>printcap - = cups</tt></i>. CUPS itself doesn't need a printcap file - anymore. However, the <tt class="filename">cupsd.conf</tt> configuration - file knows two related directives: they control if such a file should - be automatically created and maintained by CUPS for the convenience of - third party applications (example: <i class="parameter"><tt>Printcap - /etc/printcap</tt></i> and <i class="parameter"><tt>PrintcapFormat - BSD</tt></i>). These legacy programs often require the existence of - printcap file containing printernames or they will refuse to - print. Make sure CUPS is set to generate and maintain a printcap! For - details see <b class="command">man cupsd.conf</b> and other CUPS-related - documentation, like the wealth of documents on your CUPS server - itself: <a href="http://localhost:631/documentation.html" target="_top">http://localhost:631/documentation.html</a>. - </p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2957483"></a>Linking of smbd with libcups.so</h3></div></div><div></div></div><p> - Samba has a very special relationship to CUPS. The reason is: Samba - can be compiled with CUPS library support. Most recent installations - have this support enabled, and per default CUPS linking is compiled - into smbd and other Samba binaries. Of course, you can use CUPS even - if Samba is not linked against <tt class="filename">libcups.so</tt> -- but - there are some differences in required or supported configuration - then. - </p><p> - If SAMBA is compiled against libcups, then <i class="parameter"><tt>printcap = - cups</tt></i> uses the CUPS API to list printers, submit jobs, - query queues, etc. Otherwise it maps to the System V commands with an - additional <b class="command">-oraw</b> option for printing. On a Linux - system, you can use the <b class="command">ldd</b> utility to find out - details (ldd may not be present on other OS platforms, or its function - may be embodied by a different command): - </p><pre class="screen"> - transmeta:/home/kurt # ldd `which smbd` - libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x4002d000) - libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x4005a000) - libcups.so.2 => /usr/lib/libcups.so.2 (0x40123000) - [....] - </pre><p> - The line <tt class="computeroutput">libcups.so.2 => /usr/lib/libcups.so.2 - (0x40123000)</tt> shows there is CUPS support compiled - into this version of Samba.

You are on your own then to manually - configure the rest of the printing system commands (most important: - <i class="parameter"><tt>print command</tt></i>; other commands are - <i class="parameter"><tt>lppause command, lpresume command, lpq command, lprm - command, queuepause command </tt></i> and <i class="parameter"><tt>queue resume - command</tt></i>).</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2950396"></a>Simple <tt class="filename">smb.conf</tt> Settings for CUPS</h3></div></div><div></div></div><p> - To summarize, here is the simplest printing-related setup - for <tt class="filename">smb.conf</tt> to enable basic CUPS support: - </p><pre class="screen"> - - [global] - load printers = yes - printing = cups - printcap name = cups - - [printers] - comment = All Printers - path = /var/spool/samba - browseable = no - public = yes - guest ok = yes - writable = no - printable = yes - printer admin = root, @ntadmins - - </pre><p> - This is all you need for basic printing setup for CUPS. It will print - all Graphic, Text, PDF and PostScript file submitted from Windows - clients. However, most of your Windows users would not know how to - send these kind of files to print without opening a GUI - application. Windows clients tend to have local printer drivers - installed. And the GUI application's print buttons start a printer - driver. Your users also very rarely send files from the command - line. Unlike UNIX clients, they hardly submit graphic, text or PDF - formatted files directly to the spooler. They nearly exclusively print - from GUI applications, with a "printer driver" hooked in between the - applications native format and the print data stream. If the backend - printer is not a PostScript device, the print data stream is "binary", - sensible only for the target printer.

It doesn't -even write the print job to a file. It just logs the job parameters -known to Samba into the <tt class="filename">/tmp/smbprn.log</tt> file and -deletes the jobfile. Moreover, the <i class="parameter"><tt>printer -admin</tt></i> of this share is "kurt" (not the "@ntadmins" group); -guest access is not allowed; the share isn't announced in Network -Neighbourhood (so you need to know it is there), and it is only -allowing access from three hosts.

Generally, this is a bad idea. It often blocks one client's -access to the printer when another client's job is printing. It also -might freeze the first client's application while it is waiting to get -rid of the job. Also, there are frequent complaints about various jobs -being printed with their pages mixed with each other. A better concept -is the usage of a "print server": it routes all jobs through one -central system, which responds immediately, takes jobs from multiple -concurrent clients at the same time and in turn transfers them to the -printer(s) in the correct order. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2950602"></a>CUPS/Samba as a "spooling-only" Print Server; "raw" printing -with Vendor Drivers on Windows Clients</h3></div></div><div></div></div><p> -Most traditionally configured Unix print servers acting on behalf of -Samba's Windows clients represented a really simple setup. Their only -task was to manage the "raw" spooling of all jobs handed to them by -Samba. This approach meant that the Windows clients were expected to -prepare the print job file in such a way that it became fit to be fed to -the printing device. Here a native (vendor-supplied) Windows printer -driver for the target device needed to be installed on each and every -client. -</p><p> -Of course you can setup CUPS, Samba and your Windows clients in the -same, traditional and simple way. When CUPS printers are configured -for RAW print-through mode operation it is the responsibility of the -Samba client to fully render the print job (file). The file must be -sent in a format that is suitable for direct delivery to the -printer. Clients need to run the vendor-provided drivers to do -this.

In addition to Ghostscript, CUPS -uses some other filters of its own. You (or your OS vendor) may have -plugged in even more filters. CUPS handles all data file formats under -the label of various <span class="emphasis"><em>MIME types</em></span>. Every incoming -printfile is subjected to an initial -<span class="emphasis"><em>auto-typing</em></span>. The auto-typing determines its given -MIME type. A given MIME type implies zero or more possible filtering -chains relevant to the selected target printer. This section discusses -how MIME types recognition and conversion rules interact. They are -used by CUPS to automatically setup a working filtering chain for any -given input data format. -</p><p> -If CUPS rasterizes a PostScript file <span class="emphasis"><em>natively</em></span> to -a bitmap, this is done in 2 stages: -</p><div class="itemizedlist"><ul type="disc"><li><p>the first stage uses a Ghostscript device named "cups" -(this is since version 1.1.15) and produces a generic raster format -called "CUPS raster". -</p></li><li><p>the second stage uses a "raster driver" which converts -the generic CUPS raster to a device specific raster.</p></li></ul></div><p> -Make sure your Ghostscript version has the "cups" device compiled in -(check with <b class="command">gs -h | grep cups</b>). Otherwise you -may encounter the dreaded <tt class="computeroutput">Unable to convert file -0</tt> in your CUPS error_log file. To have "cups" as a -device in your Ghostscript, you either need to <span class="emphasis"><em>patch GNU -Ghostscript</em></span> and re-compile or use <a href="http://www.cups.org/ghostscript.php" target="_top">ESP Ghostscript</a>. The -superior alternative is ESP Ghostscript: it supports not just CUPS, -but 300 other devices too (while GNU Ghostscript supports only about -180). Because of this broad output device support, ESP Ghostscript is -the first choice for non-CUPS spoolers too. It is now recommended by -Linuxprinting.org for all spoolers. -</p><p> -CUPS printers may be setup to use <span class="emphasis"><em>external</em></span> -rendering paths.

Linuxprinting.org keeps all the -important facts about printer drivers, supported models and which -options are available for the various driver/printer combinations in -its <a href="http://www.linuxprinting.org/foomatic.html" target="_top">Foomatic</a> -database. Currently there are <a href="http://www.linuxprinting.org/driver_list.cgi" target="_top">245 drivers</a> -in the database: many drivers support various models, and many models -may be driven by different drivers; it's your choice! -</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2971197"></a>690 "perfect" Printers</h4></div></div><div></div></div><p> -At present there are 690 devices dubbed as working "perfectly", 181 -"mostly", 96 "partially" and 46 are "Paperweights".

The roots of today's Linuxprinting.org are in the -first <a href="http://www.linuxprinting.org/foomatic2.9/howto/" target="_top">Linux Printing -HOWTO</a> which he authored. As a side-project to this document, -which served many Linux users and admins to guide their first steps in -this complicated and delicate setup (to a scientist, printing is -"applying a structured deposition of distinct patterns of ink or toner -particles on paper substrates" <span class="emphasis"><em>;-)</em></span>, he started to -build in a little Postgres database with information about the -hardware and driver zoo that made up Linux printing of the time. This -database became the core component of today's Foomatic collection of -tools and data. In the meantime it has moved to an XML representation -of the data. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2971267"></a>Foomatic's strange Name</h4></div></div><div></div></div><p> -"Why the funny name?", you ask. When it really took off, around spring -2000, CUPS was far less popular than today, and most systems used LPD, -LPRng or even PDQ to print. CUPS shipped with a few generic "drivers" -(good for a few hundred different printer models). These didn't -support many device-specific options. CUPS also shipped with its own -built-in rasterization filter ("pstoraster", derived from -Ghostscript). On the other hand, CUPS provided brilliant support for -<span class="emphasis"><em>controlling</em></span> all printer options through -standardized and well-defined "PPD files" (PostScript Printers -Description files). Plus, CUPS was designed to be easily extensible. -</p><p> -Grant already had in his database a respectable compilation -of facts about a many more printers, and the Ghostscript "drivers" -they run with. His idea, to generate PPDs from the database info -and use them to make standard Ghostscript filters work within CUPS, -proved to work very well. It also "killed several birds with one -stone": -</p><div class="itemizedlist"><ul type="disc"><li><p>It made all current and future Ghostscript filter -developments available for CUPS;</p></li><li><p>It made available a lot of additional printer models -to CUPS users (because often the "traditional" Ghostscript way of -printing was the only one available);</p></li><li><p>It gave all the advanced CUPS options (web interface, -GUI driver configurations) to users wanting (or needing) to use -Ghostscript filters.</p></li></ul></div></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2971334"></a>cupsomatic, pdqomatic, lpdomatic, directomatic</h4></div></div><div></div></div><p> -CUPS worked through a quickly-hacked up filter script named <a href="http://www.linuxprinting.org/download.cgi?filename=cupsomatic&show=0" target="_top">cupsomatic</a>. -cupsomatic ran the printfile through Ghostscript, constructing -automatically the rather complicated command line needed. It just -required to be copied into the CUPS system to make it work. To -"configure" the way cupsomatic controls the Ghostscript rendering -process, it needs a CUPS-PPD. This PPD is generated directly from the -contents of the database. For CUPS and the respective printer/filter -combo another Perl script named "CUPS-O-Matic" did the PPD -generation. After that was working, Grant implemented within a few -days a similar thing for two other spoolers. Names chosen for the -config-generator scripts were <a href="http://www.linuxprinting.org/download.cgi?filename=lpdomatic&show=0" target="_top">PDQ-O-Matic</a> -(for PDQ) and <a href="http://www.linuxprinting.org/download.cgi?filename=lpdomatic&show=0" target="_top">LPD-O-Matic</a> -(for - you guessed it - LPD); the configuration here didn't use PPDs -but other spooler-specific files. -</p><p> -From late summer of that year, <a href="http://www.linuxprinting.org/till/" target="_top">Till Kamppeter</a> -started to put work into the database. Till had been newly employed by -<a href="http://www.mandrakesoft.com/" target="_top">MandrakeSoft</a> to -convert their printing system over to CUPS, after they had seen his -<a href="http://www.fltk.org/" target="_top">FLTK</a>-based <a href="http://cups.sourceforge.net/xpp/" target="_top">XPP</a> (a GUI frontend to -the CUPS lp-command). He added a huge amount of new information and new -printers. He also developed the support for other spoolers, like -<a href="http://ppr.sourceforge.net/" target="_top">PPR</a> (via ppromatic), -<a href="http://sourceforge.net/projects/lpr/" target="_top">GNUlpr</a> and -<a href="http://www.lprng.org/" target="_top">LPRng</a> (both via an extended -lpdomatic) and "spoolerless" printing (<a href="http://www.linuxprinting.org/download.cgi?filename=directomatic&show=0" target="_top">directomatic</a>).... -</p><p> -So, to answer your question: "Foomatic" is the general name for all -the overlapping code and data behind the "*omatic" scripts.... -- -Foomatic up to versions 2.0.x required (ugly) Perl data structures -attached the Linuxprinting.org PPDs for CUPS. It had a different -"*omatic" script for every spooler, as well as different printer -configuration files.. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2971466"></a>7.13.1.5.The <span class="emphasis"><em>Grand Unification</em></span> -achieved...</h4></div></div><div></div></div><p> -This all has changed in Foomatic versions 2.9 (Beta) and released as -"stable" 3.0. This has now achieved the convergence of all *omatic -scripts: it is called the <a href="http://www.linuxprinting.org/foomatic2.9/download.cgi?filename=foomatic-rip&show=0" target="_top">foomatic-rip</a>. -This single script is the unification of the previously different -spooler-specific *omatic scripts. foomatic-rip is used by all the -different spoolers alike. Because foomatic-rip can read PPDs (both the -original PostScript printer PPDs and the Linuxprinting.org-generated -ones), all of a sudden all supported spoolers can have the power of -PPDs at their disposal; users only need to plug "foomatic-rip" into -their system.... For users there is improved media type and source -support; paper sizes and trays are easier to configure. -</p><p> -Also, the New Generation of Linuxprinting.org PPDs doesn't contain -Perl data structures any more. If you are a distro maintainer and have -used the previous version of Foomatic, you may want to give the new -one a spin: but don't forget to generate a new-version set of PPDs, -via the new <a href="http://www.linuxprinting.org/download/foomatic/foomatic-db-engine-3.0.0beta1.tar.gz" target="_top">foomatic-db-engine</a>! -Individual users just need to generate a single new PPD specific to -their model by <a href="http://www.linuxprinting.org/kpfeifle/LinuxKongress2002/Tutorial/II.Foomatic-User/II.tutorial-handout-foomatic-user.html" target="_top">following -the steps</a> outlined in the Foomatic tutorial or further -below. This new development is truly amazing. -</p><p> -foomatic-rip is a very clever wrapper around the need to run -Ghostscript with a different syntax, different options, different -device selections and/or different filters for each different printer -or different spooler. At the same time it can read the PPD associated -with a print queue and modify the print job according to the user -selections. Together with this comes the 100% compliance of the new -Foomatic PPDs with the Adobe spec. Some really innovative features of -the Foomatic concept will surprise users: it will support custom paper -sizes for many printers; and it will support printing on media drawn -from different paper trays within the same job (in both cases: even -where there is no support for this from Windows-based vendor printer -drivers). -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2971554"></a>Driver Development outside</h4></div></div><div></div></div><p> -Most driver development itself does not happen within -Linuxprinting.org.

Not -only does it keep the printer and driver information, but it is -organized in a way that it can generate "PPD" files "on the fly" from -its internal XML-based datasets. While these PPDs are modelled to the -Adobe specification of "PostScript Printer Descriptions" (PPDs), the -Linuxprinting.org/Foomatic-PPDs don't normally drive PostScript -printers: they are used to describe all the bells and whistles you -could ring or blow on an Epson Stylus inkjet, or a HP Photosmart or -what-have-you. The main "trick" is one little additional line, not -envisaged by the PPD specification, starting with the "*cupsFilter" -keyword: it tells the CUPS daemon how to proceed with the PostScript -print file (old-style Foomatic-PPDs named the -<span class="emphasis"><em>cupsomatic</em></span> filter script, while the new-style -PPDs now call <span class="emphasis"><em>foomatic-rip</em></span>). This filter -script calls Ghostscript on the host system (the recommended variant -is ESP Ghostscript) to do the rendering work. foomatic-rip knows which -filter or internal device setting it should ask from Ghostscript to -convert the PostScript printjob into a raster format ready for the -target device. This usage of PPDs to describe the options of non-PS -printers was the invention of the CUPS developers. The rest is easy: -GUI tools (like KDE's marvellous <a href="http://printing.kde.org/overview/kprinter.phtml" target="_top">"kprinter"</a>, -or the GNOME <a href="http://gtklp.sourceforge.net/" target="_top">"gtklp"</a>, "xpp" and the CUPS -web interface) read the PPD too and use this information to present -the available settings to the user as an intuitive menu selection. -</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2971770"></a>foomatic-rip and Foomatic-PPD Download and Installation</h3></div></div><div></div></div><p> -Here are the steps to install a foomatic-rip driven "LaserJet 4 Plus" -compatible printer in CUPS (note that recent distributions of SuSE, -UnitedLinux and Mandrake may ship with a complete package of -Foomatic-PPDs plus the foomatic-rip utility. going directly to -Linuxprinting.org ensures you to get the latest driver/PPD files): -</p><div class="itemizedlist"><ul type="disc"><li><p>Surf to <a href="http://www.linuxprinting.org/printer_list.cgi" target="_top">http://www.linuxprinting.org/printer_list.cgi</a> -</p></li><li><p>Check the complete list of printers in the database: -<a href="http://www.linuxprinting.org/printer_list.cgi?make=Anyone" target="_top">http://www.linuxprinting.org/printer_list.cgi?make=Anyone</a> -</p></li><li><p>There select your model and click on the -link.</p></li><li><p>You'll arrive at a page listing all drivers working -with this model (for all printers, there will always be -<span class="emphasis"><em>one</em></span> recommended driver.

This is feature that many sites -will want to use if they migrate to Samba-3 from and NT4 style domain and do NOT want to -adopt Active Directory or an LDAP based authentication back end. This section explains -some background information regarding trust relationships and how to create them. It is now -possible for Samba-3 to NT4 trust (and vice versa), as well as Samba3 to Samba3 trusts. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2929505"></a>Features and Benefits</h2></div></div><div></div></div><p> -Samba-3 can participate in Samba-to-Samba as well as in Samba-to-MS Windows NT4 style -trust relationships. This imparts to Samba similar scalability as is possible with -MS Windows NT4. -</p><p> -Given that Samba-3 has the capability to function with a scalable backend authentication -database such as LDAP, and given it's ability to run in Primary as well as Backup Domain control -modes, the administrator would be well advised to consider alternatives to the use of -Interdomain trusts simply because by the very nature of how this works it is fragile. -That was, after all, a key reason for the development and adoption of Microsoft Active Directory. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2929534"></a>Trust Relationship Background</h2></div></div><div></div></div><p> -MS Windows NT3.x/4.0 type security domains employ a non-hierarchical security structure. -The limitations of this architecture as it affects the scalability of MS Windows networking -in large organisations is well known. Additionally, the flat-name space that results from -this design significantly impacts the delegation of administrative responsibilities in -large and diverse organisations. -</p><p> -Microsoft developed Active Directory Service (ADS), based on Kerberos and LDAP, as a means -of circumventing the limitations of the older technologies. Not every organisation is ready -or willing to embrace ADS. For small companies the older NT4 style domain security paradigm -is quite adequate, there thus remains an entrenched user base for whom there is no direct -desire to go through a disruptive change to adopt ADS. -</p><p> -Microsoft introduced with MS Windows NT the ability to allow differing security domains -to affect a mechanism so that users from one domain may be given access rights and privileges -in another domain. The language that describes this capability is couched in terms of -<span class="emphasis"><em>Trusts</em></span>. Specifically, one domain will <span class="emphasis"><em>trust</em></span> the users -from another domain. The domain from which users are available to another security domain is -said to be a trusted domain. The domain in which those users have assigned rights and privileges -is the trusting domain. With NT3.x/4.0 all trust relationships are always in one direction only, -thus if users in both domains are to have privileges and rights in each others' domain, then it is -necessary to establish two (2) relationships, one in each direction. -</p><p> -In an NT4 style MS security domain, all trusts are non-transitive. This means that if there -are three (3) domains (let's call them RED, WHITE, and BLUE) where RED and WHITE have a trust -relationship, and WHITE and BLUE have a trust relationship, then it holds that there is no -implied trust between the RED and BLUE domains. ie: Relationships are explicit and not -transitive. -</p><p> -New to MS Windows 2000 ADS security contexts is the fact that trust relationships are two-way -by default. Also, all inter-ADS domain trusts are transitive. In the case of the RED, WHITE and BLUE -domains above, with Windows 2000 and ADS the RED and BLUE domains CAN trust each other. This is -an inherent feature of ADS domains. Samba-3 implements MS Windows NT4 -style Interdomain trusts and interoperates with MS Windows 200x ADS -security domains in similar manner to MS Windows NT4 style domains. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2929617"></a>Native MS Windows NT4 Trusts Configuration</h2></div></div><div></div></div><p> -There are two steps to creating an interdomain trust relationship. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2929629"></a>NT4 as the Trusting Domain (ie. creating the trusted account)</h3></div></div><div></div></div><p> -For MS Windows NT4, all domain trust relationships are configured using the -<span class="application">Domain User Manager</span>.

Suppose, your domain is -called SAMBA, and the remote domain is called RUMBA.

You can use any password you want, but be aware that Windows NT will -not change this password until 7 days following account creation. -After the command returns successfully, you can look at the entry for the new account -(in the standard way depending on your configuration) and see that account's name is -really RUMBA$ and it has 'I' flag in the flags field. Now you're ready to confirm -the trust by establishing it from Windows NT Server. -</p><p> -Open <span class="application">User Manager for Domains</span> and from menu -<span class="guimenu">Policies</span> select <span class="guimenuitem">Trust Relationships...</span>. -Right beside <span class="guilabel">Trusted domains</span> list box press the -<span class="guimenu">Add...</span> button.

The Windows network security -domain context should be sized and scoped before implementation. Particular attention needs to be -paid to the location of the primary domain controller (PDC) as well as backup controllers (BDCs). -It should be noted that one way in which Samba-3 differs from Microsoft technology is that if one -chooses to use an LDAP authentication backend then the same database can be used by several different -domains. This means that in a complex organisation there can be a single LDAP database, that itself -can be distributed, that can simultaneously serve multiple domains (that can also be widely distributed). -</p><p> -It is recommended that from a design perspective, the number of users per server, as well as the number -of servers, per domain should be scaled according to needs and should also consider server capacity -and network bandwidth. -</p><p> -A physical network segment may house several domains, each of which may span multiple network segments. -Where domains span routed network segments it is most advisable to consider and test the performance -implications of the design and layout of a network. A Centrally located domain controller that is being -designed to serve multiple routed network segments may result in severe performance problems if the -response time (eg: ping timing) between the remote segment and the PDC is more than 100 ms. In situations -where the delay is too long it is highly recommended to locate a backup controller (BDC) to serve as -the local authentication and access control server. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2999243"></a>Server Share and Directory Layout</h4></div></div><div></div></div><p> -There are few cardinal rules to effective network design that can be broken with impunity. -The most important rule of effective network management is that simplicity is king in every -well controlled network. Every part of the infrastructure must be managed, the more complex -it is, the greater will be the demand of keeping systems secure and functional. -</p><p> -The nature of the data that must be stored needs to be born in mind when deciding how many -shares must be created. The physical disk space layout should also be taken into account -when designing where share points will be created. Keep in mind that all data needs to be -backed up, thus the simpler the disk layout the easier it will be to keep track of what must -be backed up to tape or other off-line storage medium. Always plan and implement for minimum -maintenance. Leave nothing to chance in your design, above all, do not leave backups to chance: -Backup and test, validate every backup, create a disaster recovery plan and prove that it works. -</p><p> -Users should be grouped according to data access control needs. File and directory access -is best controlled via group permissions and the use of the "sticky bit" on group controlled -directories may substantially avoid file access complaints from samba share users. -</p><p> -Many network administrators who are new to the game will attempt to use elaborate techniques -to set access controls, on files, directories, shares, as well as in share definitions. -There is the ever present danger that that administrator's successor will not understand the -complex mess that has been inherited. Remember, apparent job security through complex design -and implementation may ultimately cause loss of operations and downtime to users as the new -administrator learns to untangle your web. Keep access controls simple and effective and -make sure that users will never be interrupted by the stupidity of complexity. -</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2999304"></a>Logon Scripts</h4></div></div><div></div></div><p> -Please refer to the section of this document on Advanced Network Administration for information -regarding the network logon script options for Samba-3.

MS Windows 200x supports -NetBIOS over TCP/IP for backwards compatibility.

NetBIOS based networking uses broadcast messaging to -affect browse list management. When running NetBIOS over TCP/IP, this uses UDP based messaging. -UDP messages can be broadcast or unicast. -</p><p> -Normally, only unicast UDP messaging can be forwarded by routers. The -<b class="command">remote announce</b> parameter to smb.conf helps to project browse announcements -to remote network segments via unicast UDP. Similarly, the -<b class="command">remote browse sync</b> parameter of <tt class="filename">smb.conf</tt> -implements browse list collation using unicast UDP. -</p><p> -Secondly, in those networks where Samba is the only SMB server technology, -wherever possible <tt class="filename">nmbd</tt> should be configured on one (1) machine as the WINS -server. This makes it easy to manage the browsing environment. If each network -segment is configured with it's own Samba WINS server, then the only way to -get cross segment browsing to work is by using the -<b class="command">remote announce</b> and the <b class="command">remote browse sync</b> -parameters to your <tt class="filename">smb.conf</tt> file. -</p><p> -If only one WINS server is used for an entire multi-segment network then -the use of the <b class="command">remote announce</b> and the -<b class="command">remote browse sync</b> parameters should NOT be necessary. -</p><p> -As of Samba 3 WINS replication is being worked on. The bulk of the code has -been committed, but it still needs maturation. This is NOT a supported feature -of the Samba-3.0.0 release. Hopefully, this will become a supported feature -of one of the Samba-3 release series. -</p><p> -Right now Samba WINS does not support MS-WINS replication. This means that -when setting up Samba as a WINS server there must only be one <tt class="filename">nmbd</tt> -configured as a WINS server on the network. Some sites have used multiple Samba WINS -servers for redundancy (one server per subnet) and then used -<b class="command">remote browse sync</b> and <b class="command">remote announce</b> -to affect browse list collation across all segments. Note that this means clients -will only resolve local names, and must be configured to use DNS to resolve names -on other subnets in order to resolve the IP addresses of the servers they can see -on other subnets. This setup is not recommended, but is mentioned as a practical -consideration (ie: an 'if all else fails' scenario). -</p><p> -Lastly, take note that browse lists are a collection of unreliable broadcast -messages that are repeated at intervals of not more than 15 minutes. This means -that it will take time to establish a browse list and it can take up to 45 -minutes to stabilise, particularly across network segments. -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2906017"></a>TCP/IP - without NetBIOS</h3></div></div><div></div></div><p> -All TCP/IP using systems use various forms of host name resolution.

This list -contains machines that are ready to offer file and/or print services -to other machines within the network. Thus it does not include -machines which aren't currently able to do server tasks. The browse -list is heavily used by all SMB clients. Configuration of SMB -browsing has been problematic for some Samba users, hence this -document. -</p><p> -MS Windows 2000 and later, as with Samba 3 and later, can be -configured to not use NetBIOS over TCP/IP. When configured this way, -it is imperative that name resolution (using DNS/LDAP/ADS) be correctly -configured and operative. Browsing will NOT work if name resolution -from SMB machine names to IP addresses does not function correctly. -</p><p> -Where NetBIOS over TCP/IP is enabled use of a WINS server is highly -recommended to aid the resolution of NetBIOS (SMB) names to IP addresses. -WINS allows remote segment clients to obtain NetBIOS name_type information -that can NOT be provided by any other means of name resolution. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2907468"></a>Browsing support in Samba</h3></div></div><div></div></div><p> -Samba facilitates browsing. The browsing is supported by <span class="application">nmbd</span> -and is also controlled by options in the <tt class="filename">smb.conf</tt> file. -Samba can act as a local browse master for a workgroup and the ability -to support domain logons and scripts is now available. -</p><p> -Samba can also act as a domain master browser for a workgroup. This -means that it will collate lists from local browse masters into a -wide area network server list. In order for browse clients to -resolve the names they may find in this list, it is recommended that -both Samba and your clients use a WINS server. -</p><p> -Note that you should NOT set Samba to be the domain master for a -workgroup that has the same name as an NT Domain: on each wide area -network, you must only ever have one domain master browser per workgroup, -regardless of whether it is NT, Samba or any other type of domain master -that is providing this service. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -Nmbd can be configured as a WINS server, but it is not -necessary to specifically use Samba as your WINS server. MS Windows -NT4, Server or Advanced Server 2000 or 2003 can be configured as -your WINS server. In a mixed NT/2000/2003 server and Samba environment on -a Wide Area Network, it is recommended that you use the Microsoft -WINS server capabilities. In a Samba-only environment, it is -recommended that you use one and only one Samba server as your WINS server. -</p></div><p> -To get browsing to work you need to run nmbd as usual, but will need -to use the <i class="parameter"><tt>workgroup</tt></i> option in <tt class="filename">smb.conf</tt> -to control what workgroup Samba becomes a part of. -</p><p> -Samba also has a useful option for a Samba server to offer itself for -browsing on another subnet. It is recommended that this option is only -used for 'unusual' purposes: announcements over the internet, for -example.

Try a debug level of 2 or 3 for finding -problems. Also note that the current browse list usually gets stored -in text form in a file called <tt class="filename">browse.dat</tt>. -</p><p> -Note that if it doesn't work for you, then you should still be able to -type the server name as <tt class="filename">\\SERVER</tt> in filemanager then -hit enter and filemanager should display the list of available shares. -</p><p> -Some people find browsing fails because they don't have the global -<i class="parameter"><tt>guest account</tt></i> set to a valid account.

MS Windows -9X clients are not able to do this and thus will NOT be able to browse -server resources. -</em></span></p><p> -The other big problem people have is that their broadcast address, -netmask or IP address is wrong (specified with the "interfaces" option -in <tt class="filename">smb.conf</tt>) -</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2907654"></a>Browsing across subnets</h3></div></div><div></div></div><p> -Since the release of Samba 1.9.17(alpha1), Samba has supported the -replication of browse lists across subnet boundaries. This section -describes how to set this feature up in different settings. -</p><p> -To see browse lists that span TCP/IP subnets (ie. networks separated -by routers that don't pass broadcast traffic), you must set up at least -one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing -NetBIOS name to IP address translation to be done by doing a direct -query of the WINS server. This is done via a directed UDP packet on -port 137 to the WINS server machine. The reason for a WINS server is -that by default, all NetBIOS name to IP address translation is done -by broadcasts from the querying machine. This means that machines -on one subnet will not be able to resolve the names of machines on -another subnet without using a WINS server. -</p><p> -Remember, for browsing across subnets to work correctly, all machines, -be they Windows 95, Windows NT, or Samba servers must have the IP address -of a WINS server given to them by a DHCP server, or by manual configuration -(for Win95 and WinNT, this is in the TCP/IP Properties, under Network -settings) for Samba this is in the <tt class="filename">smb.conf</tt> file. -</p><div xmlns:ns21="" class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2907703"></a>How does cross subnet browsing work ?</h4></div></div><div></div></div><p> -Cross subnet browsing is a complicated dance, containing multiple -moving parts. It has taken Microsoft several years to get the code -that achieves this correct, and Samba lags behind in some areas. -Samba is capable of cross subnet browsing when configured correctly. -</p><p> -Consider a network set up as follows : -</p><ns21:p> - -</ns21:p><pre class="programlisting"> - (DMB) - N1_A N1_B N1_C N1_D N1_E - | | | | | - ------------------------------------------------------- - | subnet 1 | - +---+ +---+ - |R1 | Router 1 Router 2 |R2 | - +---+ +---+ - | | - | subnet 2 subnet 3 | - -------------------------- ------------------------------------ - | | | | | | | | - N2_A N2_B N2_C N2_D N3_A N3_B N3_C N3_D - (WINS) -</pre><ns21:p> -</ns21:p><p> -Consisting of 3 subnets (1, 2, 3) connected by two routers -(R1, R2) - these do not pass broadcasts. Subnet 1 has 5 machines -on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume -for the moment that all these machines are configured to be in the -same workgroup (for simplicity's sake). Machine N1_C on subnet 1 -is configured as Domain Master Browser (ie. it will collate the -browse lists for the workgroup). Machine N2_D is configured as -WINS server and all the other machines are configured to register -their NetBIOS names with it. -</p><p> -As all these machines are booted up, elections for master browsers -will take place on each of the three subnets. Assume that machine -N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on -subnet 3 - these machines are known as local master browsers for -their particular subnet. N1_C has an advantage in winning as the -local master browser on subnet 1 as it is set up as Domain Master -Browser. -</p><p> -On each of the three networks, machines that are configured to -offer sharing services will broadcast that they are offering -these services. The local master browser on each subnet will -receive these broadcasts and keep a record of the fact that -the machine is offering a service. This list of records is -the basis of the browse list. For this case, assume that -all the machines are configured to offer services so all machines -will be on the browse list. -</p><p> -For each network, the local master browser on that network is -considered 'authoritative' for all the names it receives via -local broadcast. This is because a machine seen by the local -master browser via a local broadcast must be on the same -network as the local master browser and thus is a 'trusted' -and 'verifiable' resource. Machines on other networks that -the local master browsers learn about when collating their -browse lists have not been directly seen - these records are -called 'non-authoritative'. -</p><p> -At this point the browse lists look as follows (these are -the machines you would see in your network neighborhood if -you looked in it on a particular network right now). -</p><ns21:p> -</ns21:p><div class="table"><a name="id2907818"></a><p class="title"><b>Table 10.1.

A Windows NT4 user enters a username, a password - and selects the domain name to which the logon will attempt to take place. During the logon - process the client machine reads the NTConfig.POL file from the NETLOGON share on the authenticating - server, modifies the local registry values according to the settings in this file. - </p><p> - Windows 2K GPOs are very feature rich. They are NOT stored in the NETLOGON share, rather part of - a Windows 200x policy file is stored in the Active Directory itself and the other part is stored - in a shared (and replicated) volume called the SYSVOL folder. This folder is present on all Active - Directory domain controllers. The part that is stored in the Active Directory itself is called the - group policy container (GPC), and the part that is stored in the replicated share called SYSVOL is - known as the group policy template (GPT). - </p><p> - With NT4 clients the policy file is read and executed upon only as each user logs onto the network. - MS Windows 200x policies are much more complex - GPOs are processed and applied at client machine - startup (machine specific part) and when the user logs onto the network the user specific part - is applied. In MS Windows 200x style policy management each machine and/or user may be subject - to any number of concurrently applicable (and applied) policy sets (GPOs). Active Directory allows - the administrator to also set filters over the policy settings. No such equivalent capability - exists with NT4 style policy files. - </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2982130"></a>Administration of Win2K / XP Policies</h4></div></div><div></div></div><p> - Instead of using the tool called <span class="application">The System Policy Editor</span>, commonly called Poledit (from the - executable name <b class="command">poledit.exe</b>), <span class="acronym">GPOs</span> are created and managed using a - <span class="application">Microsoft Management Console</span> <span class="acronym">(MMC)</span> snap-in as follows:</p><div class="procedure"><ol type="1"><li><p> - Go to the Windows 200x / XP menu <span class="guimenu">Start->Programs->Administrative Tools</span> - and select the MMC snap-in called <span class="guimenuitem">Active Directory Users and Computers</span> - </p></li><li><p> - Select the domain or organizational unit (OU) that you wish to manage, then right click - to open the context menu for that object, select the properties item. - </p></li><li><p> - Now left click on the <span class="guilabel">Group Policy</span> tab, then left click on the New tab.

SWAT is a tool that will allow web based configuration -of samba. It has a wizard that may help to get samba configured quickly, it has context -sensitive help on each smb.conf parameter, it provides for monitoring of current state -of connection information, and it allows network wide MS Windows network password -management. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id3002261"></a>Features and Benefits</h2></div></div><div></div></div><p> -There are network administrators who believe that it is a good idea to write systems -documentation inside configuration files, for them SWAT will aways be a nasty tool. SWAT -does not store the configuration file in any intermediate form, rather, it stores only the -parameter settings, so when SWAT writes the smb.conf file to disk it will write only -those parameters that are at other than the default settings. The result is that all comments -will be lost from the <tt class="filename">smb.conf</tt> file. Additionally, the parameters will be written back in -internal ordering. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -So before using SWAT please be warned - SWAT will completely replace your smb.conf with -a fully optimised file that has been stripped of all comments you might have placed there -and only non-default settings will be written to the file. -</p></div><div xmlns:ns96="" class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id3002111"></a>Enabling SWAT for use</h3></div></div><div></div></div><p> -SWAT should be installed to run via the network super daemon.

This causes the Primary Domain Controller to claim domain specific NetBIOS name that identifies it as a domain master browser for its given domain/workgroup. Local master browsers in the same domain/workgroup on broadcast-isolated subnets then ask for a complete copy of the browse list for the whole wide area network. Browser clients will then contact their local master browser, and will receive the domain-wide browse list, instead of just the list for their broadcast-isolated subnet. -</p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2873240"></a>Domain Control - Example Configuration</h2></div></div><div></div></div><p> +</p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2870187"></a>Domain Control - Example Configuration</h2></div></div><div></div></div><p> The first step in creating a working Samba PDC is to understand the parameters necessary -in <tt class="filename">smb.conf</tt>.

To do that, you can use the 'smbpasswd' utility. Creating the trusted domain account is very similar to creating a trusted machine account. Suppose, your domain is called SAMBA, and the remote domain is called RUMBA. The first step will be to issue this command from your favourite shell: -</p><ns44:p> -</ns44:p><pre class="screen"> +</p><p> +</p><pre class="screen"> <tt class="prompt">root# </tt> <b class="userinput"><tt>smbpasswd -a -i rumba</tt></b> - New SMB password: XXXXXXXX - Retype SMB password: XXXXXXXX - Added user rumba$ -</pre><ns44:p> +New SMB password: <b class="userinput"><tt>XXXXXXXX</tt></b> +Retype SMB password: <b class="userinput"><tt>XXXXXXXX</tt></b> +Added user rumba$ +</pre><p> where <tt class="option">-a</tt> means to add a new account into the passdb database and <tt class="option">-i</tt> means: ''create this account with the InterDomain trust flag'' -</ns44:p><p> +</p><p> The account name will be 'rumba$' (the name of the remote domain) </p><p> After issuing this command you'll be asked to enter the password for the account. You can use any password you want, but be aware that Windows NT will not change this password until 7 days following account creation. After the command returns successfully, you can look at the entry for the new account -(in the standard way depending on your configuration) and see that account's name is -really RUMBA$ and it has 'I' flag in the flags field. Now you're ready to confirm +(in the standard way as appropriate for your configuration) and see that account's name is +really RUMBA$ and it has the 'I' flag set in the flags field.
