We face distractions and pressures 3 that drive us to seek proven, working case scenarios that can be easily 4 implemented. Often this approach lands us in trouble. There is a 5 saying that, geometrically speaking, the shortest distance between two 6 points is a straight line, but practically we find that the quickest 7 route to a stable network solution is the long way around. 8 </p><p> 9 This book is your means to the straight path. It provides step-by-step, 10 proven, working examples of Samba deployments. If you want to deploy 11 Samba-3 with the least effort, or if you want to become an expert at deploying 12 Samba-3 without having to search through lots of documentation, this 13 book is the ticket to your destination. 14 </p><p> 15 Samba is software that can be run on a platform other than Microsoft Windows, 16 for example, UNIX, Linux, IBM System 390, OpenVMS, and other operating systems. 17 Samba uses the TCP/IP protocol that is installed on the host server. When 18 correctly configured, it allows that host to interact with a Microsoft Windows 19 client or server as if it is a Windows file and print server. This book 20 will help you to implement Windows-compatible file and print services. 21 </p><p> 22 The examples presented in this book are typical of various businesses and 23 reflect the problems and challenges they face. Care has been taken to preserve 24 attitudes, perceptions, practices, and demands from real network case studies. 25 The maximum benefit may be obtained from this book by working carefully through 26 each exercise. You may be in a hurry to satisfy a specific need, so feel 27 free to locate the example that most closely matches your need, copy it, and 28 innovate as much as you like. Above all, enjoy the process of learning the 29 secrets of MS Windows networking that is truly liberated by Samba. 30 </p><p> 31 The focus of attention in this book is Samba-3. Specific notes are made in 32 respect of how Samba may be made secure. This book does not attempt to provide 33 detailed information regarding secure operation and configuration of peripheral 34 services and applications such as OpenLDAP, DNS and DHCP, the need for which 35 can be met from other resources that are dedicated to the subject. 36 </p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id274305"></a>Why Is This Book Necessary?</h2></div></div></div><p> 37 This book is the result of observations and feedback. The feedback from 38 the Samba-HOWTO-Collection has been positive and complimentary. There 39 have been requests for far more worked examples, a 40 “<span class="quote">Samba Cookbook,</span>” and for training materials to 41 help kick-start the process of mastering Samba. 42 </p><p> 43 The Samba mailing lists users have asked for sample configuration files 44 that work. It is natural to question one's own ability to correctly 45 configure a complex tool such as Samba until a minimum necessary 46 knowledge level has been attained. 47 </p><p> 48 The Samba-HOWTO-Collection as does <span class="emphasis"><em>The Official Samba-3 HOWTO and 49 Reference Guide</em></span> documents Samba features and functionality in 50 a topical context. This book takes a completely different approach. It 51 walks through Samba network configurations that are working within particular 52 environmental contexts, providing documented step-by-step implementations. 53 All example case configuration files, scripts, and other tools are provided 54 on the CD-ROM. This book is descriptive, provides detailed diagrams, and 55 makes deployment of Samba-3 a breeze. 56 </p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id274342"></a>Samba 3.0.20 Update Edition</h3></div></div></div><p> 57 The Samba 3.0.x series has been remarkably popular. At the time this book first 58 went to print samba-3.0.2 was being released. There have been significant modifications 59 and enhancements between samba-3.0.2 and samba-3.0.14 (the current release) that 60 necessitate this documentation update. This update has the specific intent to 61 refocus this book so that its guidance can be followed for samba-3.0.20 62 and beyond. Further changes are expected as Samba-3 matures further and will 63 be reflected in future updates. 64 </p><p> 65 The changes shown in <a href="preface.html#pref-new" title="Table�1.�Samba Changes 3.0.2 to 3.0.20">???</a> are incorporated in this update. 66 </p><div class="table"><a name="pref-new"></a><p class="title"><b>Table�1.�Samba Changes 3.0.2 to 3.0.20</b></p><div class="table-contents"><table summary="Samba Changes 3.0.2 to 3.0.20" border="1"><colgroup><col align="left"><col align="justify"></colgroup><thead><tr><th align="left"> 67 <p> 68 New Feature 69 </p> 70 </th><th align="left"> 71 <p> 72 Description 73 </p> 74 </th></tr></thead><tbody><tr><td align="left"> 75 <p> 76 Winbind Case Handling 77 </p> 78 </td><td align="justify"> 79 <p> 80 User and group names returned by <code class="literal">winbindd</code> are now converted to lower case 81 for better consistency.

UNIX and Linux 131 training is best obtained from books dedicated to the subject. This book 132 assumes that you have at least the basic skill necessary to use these operating 133 systems, and that you can use a basic system editor to edit and configure files. 134 It has been written with the assumption that you have experience with Samba, 135 have read <span class="emphasis"><em>The Official Samba-3 HOWTO and Reference Guide</em></span> and 136 the Samba-HOWTO-Collection, or that you have familiarity with Microsoft Windows. 137 </p><p> 138 If you do not have this experience, you can follow the examples in this book but may 139 find yourself at times intimidated by assumptions made. In this situation, you 140 may need to refer to administrative guides or manuals for your operating system 141 platform to find what is the best method to achieve what the text of this book describes. 142 </p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id315668"></a>Approach</h2></div></div></div><p> 143 The first chapter deals with some rather thorny network analysis issues. Do not be 144 put off by this. The information you glean, even without a detailed understanding 145 of network protocol analysis, can help you understand how Windows networking functions. 146 </p><p> 147 Each following chapter of this book opens with the description of a networking solution 148 sought by a hypothetical site. Bob Jordan is a hypothetical decision maker 149 for an imaginary company, <code class="constant">Abmas Biz NL</code>. We will use the 150 non-existent domain name <code class="constant">abmas.biz</code>. All <span class="emphasis"><em>facts</em></span> 151 presented regarding this company are fictitious and have been drawn from a variety of real 152 business scenarios over many years. Not one of these reveal the identify of the 153 real-world company from which the scenario originated. 154 </p><p> 155 In any case, Mr. Jordan likes to give all his staff nasty little assignments. 156 Stanley Saroka is one of his proteges; Christine Roberson is the network administrator 157 Bob trusts. Jordan is inclined to treat other departments well because they finance 158 Abmas IT operations. 159 </p><p> 160 Each chapter presents a summary of the network solution we have chosen to 161 demonstrate together with a rationale to help you to understand the 162 thought process that drove that solution. The chapter then documents in precise 163 detail all configuration files and steps that must be taken to implement the 164 example solution. Anyone wishing to gain serious value from this book will 165 do well to take note of the implications of points made, so watch out for the 166 <span class="emphasis"><em>this means that</em></span> notations. 167 </p><p> 168 Each chapter has a set of questions and answers to help you to 169 to understand and digest key attributes of the solutions presented. 170 </p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id315719"></a>Summary of Topics</h2></div></div></div><p> 171 The contents of this second edition of <span class="emphasis"><em>Samba-3 by Example</em></span> 172 have been rearranged based on feedback from purchasers of the first edition. 173 </p><p> 174 Clearly the first edition contained most of what was needed and that was missing 175 from other books that cover this difficult subject. The new arrangement adds 176 additional material to meet consumer requests and includes changes that originated 177 as suggestions for improvement. 178 </p><p> 179 Chapter 1 now dives directly into the heart of the implementation of Windows 180 file and print server networks that use Samba at the heart. 181 </p><div class="variablelist"><dl><dt><span class="term">Chapter 1 No Frills Samba Servers.</span></dt><dd><p> 182 Here you design a solution for three different business scenarios, each for a 183 company called Abmas. There are two simple networking problems and one slightly 184 more complex networking challenge. In the first two cases, Abmas has a small 185 simple office, and they want to replace a Windows 9x peer-to-peer network. The 186 third example business uses Windows 2000 Professional. This must be simple, 187 so let's see how far we can get. If successful, Abmas grows quickly and 188 soon needs to replace all servers and workstations. 189 </p><p><span class="emphasis"><em>TechInfo</em></span> This chapter demands: 190 </p><div class="itemizedlist"><ul type="disc"><li><p>Case 1: The simplest <code class="filename">smb.conf</code> file that may 191 reasonably be used. Works with Samba-2.x also. This 192 configuration uses Share Mode security. Encrypted 193 passwords are not used, so there is no 194 <code class="filename">smbpasswd</code> file. 195 </p></li><li><p>Case 2: Another simple <code class="filename">smb.conf</code> file that adds 196 WINS support and printing support. This case deals with 197 a special requirement that demonstrates how to deal with 198 purpose-built software that has a particular requirement 199 for certain share names and printing demands. This 200 configuration uses Share Mode security and also works with 201 Samba-2.x. Encrypted passwords are not used, so there is no 202 <code class="filename">smbpasswd</code> file. 203 </p></li><li><p>Case 3: This <code class="filename">smb.conf</code> configuration uses User Mode 204 security. The file share configuration demonstrates 205 the ability to provide master access to an administrator 206 while restricting all staff to their own work areas. 207 Encrypted passwords are used, so there is an implicit 208 <code class="filename">smbpasswd</code> file. 209 </p></li></ul></div><p> 210 </p></dd><dt><span class="term">Chapter 2 Small Office Networking.</span></dt><dd><p> 211 Abmas is a successful company now. They have 50 network users 212 and want a little more varoom from the network. This is a typical 213 small office and they want better systems to help them to grow. This is 214 your chance to really give advanced users a bit more functionality and usefulness. 215 </p><p><span class="emphasis"><em>TechInfo</em></span> This <code class="filename">smb.conf</code> file 216 makes use of encrypted passwords, so there is an <code class="filename">smbpasswd</code> 217 file. It also demonstrates use of the <em class="parameter"><code>valid users</code></em> and 218 <em class="parameter"><code>valid groups</code></em> to restrict share access. The Windows 219 clients access the server as Domain members. Mobile users log onto 220 the Domain while in the office, but use a local machine account while on the 221 road. The result is an environment that answers mobile computing user needs. 222 </p></dd><dt><span class="term">Chapter 3 Secure Office Networking.</span></dt><dd><p> 223 Abmas is growing rapidly now. Money is a little tight, but with 130 224 network users, security has become a concern. They have many new machines 225 to install and the old equipment will be retired. This time they want the 226 new network to scale and grow for at least two years. Start with a sufficient 227 system and allow room for growth. You are now implementing an Internet 228 connection and have a few reservations about user expectations. 229 </p><p><span class="emphasis"><em>TechInfo</em></span> This <code class="filename">smb.conf</code> file 230 makes use of encrypted passwords, and you can use a <code class="filename">tdbsam</code> 231 password backend. Domain logons are introduced. Applications are served from the central 232 server. Roaming profiles are mandated. Access to the server is tightened up 233 so that only domain members can access server resources. Mobile computing 234 needs still are catered to. 235 </p></dd><dt><span class="term">Chapter 4 The 500 User Office.</span></dt><dd><p> 236 The two-year projections were met. Congratulations, you are a star. 237 Now Abmas needs to replace the network. Into the existing user base, they 238 need to merge a 280-user company they just acquired. It is time to build a serious 239 network. There are now three buildings on one campus and your assignment is 240 to keep everyone working while a new network is rolled out. Oh, isn't it nice 241 to roll out brand new clients and servers! Money is no longer tight, you get 242 to buy and install what you ask for. You will install routers and a firewall. 243 This is exciting! 244 </p><p><span class="emphasis"><em>TechInfo</em></span> This <code class="filename">smb.conf</code> file 245 makes use of encrypted passwords, and a <code class="filename">tdbsam</code> 246 password backend is used. You are not ready to launch into LDAP yet, so you 247 accept the limitation of having one central Domain Controller with a Domain 248 Member server in two buildings on your campus. A number of clever techniques 249 are used to demonstrate some of the smart options built into Samba. 250 </p></dd><dt><span class="term">Chapter 5 Making Happy Users.</span></dt><dd><p> 251 Congratulations again. Abmas is happy with your services and you have been given another raise. 252 Your users are becoming much more capable and are complaining about little 253 things that need to be fixed. Are you up to the task? Mary says it takes her 20 minutes 254 to log onto the network and it is killing her productivity. Email is a bit <span class="emphasis"><em> 255 unreliable</em></span> have you been sleeping on the job? We do not discuss the 256 technology of email but when the use of mail clients breaks because of networking 257 problems, you had better get on top of it. It's time for a change. 258 </p><p><span class="emphasis"><em>TechInfo</em></span> This <code class="filename">smb.conf</code> file 259 makes use of encrypted passwords; a distributed <code class="filename">ldapsam</code> 260 password backend is used. Roaming profiles are enabled. Desktop profile controls 261 are introduced. Check out the techniques that can improve the user experience 262 of network performance. As a special bonus, this chapter documents how to configure 263 smart downloading of printer drivers for drag-and-drop printing support. And, yes, 264 the secret of configuring CUPS is clearly documented. Go for it; this one will 265 tease you, too. 266 </p></dd><dt><span class="term">Chapter 6 A Distributed 2000 User Network.</span></dt><dd><p> 267 Only eight months have passed, and Abmas has acquired another company. You now need to expand 268 the network further. You have to deal with a network that spans several countries. 269 There are three new networks in addition to the original three buildings at the head-office 270 campus. The head office is in New York and you have branch offices in Washington, Los Angeles, and 271 London. Your desktop standard is Windows XP Professional. In many ways, everything has changed 272 and yet it must remain the same. Your team is primed for another roll-out. You know there are 273 further challenges ahead. 274 </p><p><span class="emphasis"><em>TechInfo</em></span> Slave LDAP servers are introduced. Samba is 275 configured to use multiple LDAP backends.
