Without Simple Network Management Protocol (SNMP), network administrators might have to actually get out of their chairs and go see what's up with all of the network-connected equipment under their authority. Perish the thought. Essential SNMP explains how the management protocol works and how it's implemented by several operating systems and pieces of equipment. More importantly, this book shows its reader--who should be a network administrator who's familiar with the problems of running a distributed network--how SNMP can earn its place as a network administration tool. In other words, this book examines SNMP as a strategic resource as well as a technical phenomenon.
Because it's oriented toward SNMP as a tool, much of the coverage in this book has to do with software that uses SNMP to provide network monitoring and control services. After a strengths-and-weaknesses overview of a number of SNMP packages, the authors use mainly HP OpenView, Castle Rock SNMPc, and Net-SNMP (the last in combination with Perl scripting) to demonstrate how SNMP works and how to take advantage of it. It's the scripting that really distinguishes this book from other SNMP books, by the way. It's integral to the authors' presentation, and the latter half of this book is packed with shell and Perl listings. --David Wall
Topics covered: Simple Network Management Protocol (SNMP) and its applicability as a network management tool. Details like object identifiers (OIDs), management information bases (MIBs), traps, and community strings are defined and explained. The configuration of SNMP agents is detailed for several software packages and operating systems, and the integration of SNMP and scripts (in shell languages and in Perl) is covered nicely.
Book Description
Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.
O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include:
- Expanded coverage of SNMPv1, SNMPv2, and SNMPv3
- Expanded coverage of SNMPc
- The concepts behind network management and change management
- RRDTool and Cricket
- The use of scripts for a variety of tasks
- How Java can be used to create SNMP applications
- Net-SNMP's Perl module
The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents.
Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

Disappointing.......2007-05-25
Most of the books in this series are very technical and go into serious details. This one reads like a compendium of owner's manuals. A really good book on SNMP is needed and this one is not it.
1/4 good.......2007-05-03
This book is good up till you get 1/4 of the way through it. The first quarter of the book is good and it goes over general SNMP stuff then history different versions etc. The last 3/4 of this book cover configuring proprietary monitoring systems like open view and solar winds.
I dont care about open view.. or solar winds.. i wanted to learn about snmp... not some vendors software package. Im suprised that this got published with such a general title.. when really the book is an snmp intro, followed by how to setup a proprietary monitoring tool.
Great book on SNMP starts from the beginning.......2007-02-21
I hadn't seen a new book on SNMP come out in some time, and the older ones I had read were so abstract and unhelpful that I was reluctant to try another one. This book, though not perfect, is much better than the older books I have looked at on the subject. For one thing, it just didn't dive into the subject with a bunch of confusing graphs and object trees assuming I already knew the big picture.
Chapter one is just a general introduction to SNMP and network management. Chapter 2 goes into details on both SNMPv1 and SNMPv2. It talks about how SNMP sends and receives information, how to read MIB files, and about SNMP communities. It looks in detail at three MIB's - MIB-II, Host Resources, and RMON. MIB-II is a very important management group because every device that supports SNMP must also support MIB-II, thus objects from MIB-II are used in examples through the whole book. Chapter 3 introduces SNMPv3, which addresses the security problems present in v1 and v2.
Next the book introduces the idea of a network management architecture. It stresses that you need a plan that helps you use Network Management Stations (NMS's) effectively in order to effectively manage your network. This section includes how to properly choose your hardware and what questions you need to ask yourself. Next the book discusses actually installing and running your software. Specifically HP's OpenView Network Node Manager and Castle Rock's SNMPc Enterprise Edition are discussed. Included are detailed instructions along with screenshots of the application. Next there are instructions on how to configure SNMP agents. You are walked through some standard configuration parameters plus some advanced parameters that sometimes crop up. Once again there are plenty of screen shots to help you know you are on the right path.
Now that you've been walked through the configuration of your system and the installation of software, the book shows you how to use the three basic SNMP operations of snmpget, snmpset, and snmpwalk. A group of Perl scripts are shown that set, get, and walk objects. Next HP OpenView and Net-SNMP are used to perform the same operations from the command line. A third alternative is demonstrated that uses OpenView's graphical MIB Browser. Next is a discussion of how to set up SNMP to poll your devices at certain intervals and to set thresholds that require action if crossed. Again Perl scripts enter the discussion for configuring this set-up. SNMPc and OpenView screen shots show you how to configure this using graphical interfaces, and what to expect. Next the book discusses traps, which are how an agent sends a monitoring station asynchronous notification about certain key conditions that may require action. The book demonstrates how to handle traps using OpenView and Perl scripts. Next the book shows how to read, configure, and even define your own traps.
The book now turns to the problem of agents that need to be extended in their abilities. The book discusses the answer to this problem - extensible SNMP agents - and three of them in particular - the OpenView, Net-SNMP, and SystemEdge agents. Next are some interesting scripts for automating common system administration tasks. Issues covered by these little scripts include determining who is logging into your machine, a port monitor, service monitoring, and switching port control, among others. There is then a discussion on MRTG (Multi Router Traffic Grapher), a trend analysis tool that generates image files and whose output is viewable from a web browser. Complete instructions on installing and using the tool are given. The next tool discussed is RRDtool, which in network management will most likely be used to store and process data collected via SNMP. However RRDtool can be used for many diverse purposes that have nothing to do with computer networks. The last chapter in the book is an odd one on using Java with SNMP. Specifically, the book presents the Java SNMP API known as SNMP4J. It doesn't really seem to add any functionality other than being an alternative for people who don't like to use Perl.
I liked this book very much. It had many good examples and it answered all of the questions I had previously had on SNMP starting from the beginning with what is SNMP and what can it do for you? I would highly recommend it to any network administrator who is planning on workng with SNMP.
Essential SNMP, Second Edition, Review.......2007-01-17
An excellent book that can help not only network engineers but Unix system administrators.
A lot of doubts that I had about SNMP went away and I feel much more relaxed with this topic in technical circles.
Good book, but where is there one for idiots?.......2007-01-11
I pretty much hate SNMP. It's stems from not understanding it. This book has given me a grasp on some of the concepts, but has refered to a few things that I am supposed to already know. It's not for beginners.

Excellent book for learning more about managing multicultural organisations........2006-08-28
This is an excellent book for learning more about managing multicultural organisations. Already in its second edition after being first published in 1995, it has improved. The COM or Cultural Orientation Model integrates all the cultural dimensions of famous authors Hofstede, Hampden-Turner and Trompenaars, Stewart and Bennett/Rhinesmith, Kluckhohn and Strondtbeck/Hall and Edwart Hall into a cartwheel.
Though the authors are very much pro-convergence (even claiming in Chapter 1 that Global harmonization of consumer buying preferences will dominate certain industry-goods and services-sectors.) as to Globalization they manage to build up a comprehensive argument about the high role of culture in the process of organizational globalization.
Busy international managers could find the approach of breaking the complexities of cultural differences into value orientations a bit theoretical in the absence of case examples and critical incidents. There are some good case studies in chapter 4:A Survey of Cultural Patterns but there are too few of them in the whole book. In fact more of these would have helped in getting a vital point accross that cultural boundaries are not national boundaries. For people involved in designing performance management systems and strategic planning in multicultural organisations this book is highly recommended reading. HR-practitioners in multicultural organizations would also benefit from reading this book.
Which type is to become a global manager?.......2001-01-22
Recently I wrote a book about multinational management published in 1968. After finishing this book, I realized that the conflicts between multicultural and multinational difference are stands still under the similar managerial circumstance, though we are living in the digital-dominated world. So I studied this book compared with its' phenomenon as described in "International Management". Keeping a flexible communication skill in multinational-cultural is the key factor to achieve meaningful outcome. For this, the open-minded, instructive and far-sighted personality required first. When they acknowledged difference not wrong each other, they can start to talk about what they want for negotiation, next proceed to persuade or yield a little. This means the more internationalized people there as a matchmaker, the more the company benefited from them. Then how to get Mr. Right for global manager? They all born naturally? Or trained? Both are all right. Person who has got global brain with digital management skill (as Mr. Bill Gatz called) must appeal to adapt extreme change and more action to cope with international risky problem. They could continue to get or lose by trial and error and learned what's the best, step by step and case by case. There are no standard learning system to teach them. That's not the lost rather than investment for human resources for each company ultimately. If you are would-be-global manager or second-rate reginal manager or have a dream of international manager, read this book and write down and analyze what's your strong/weak point more carefully. Then take into action to the first-rate global manager. If anyone who is in a top-management read, they can set effective multinational goal to come and get. How about students or average person? Of course, they will be fine.
Valuable guide to building a successful worldwide company........1998-10-11
This book should be on the desk of every marketing and human resources manager involved in foreign trade. It is not only for larger companies that have already built a global sales network. It is also for beginners who should consider these cross-cultural factors BEFORE they start selling their goods and services in overseas markets. John R. Jagoe, Director, Export Institute.

Customer Reviews:
Good book, some dated examples, frequent missing CD.......2005-07-23
I have enjoyed this book. In most cases I can skim the sections I know, skipping examples, and do well on the tests so it is very well structured. There are lots of excellent examples flushing out contents for the total newbie. A lot of thought went into the projects and case studies. If you are looking for a good overview of markting concepts and have a solid instructor to lead discussions about them, this is a great textbook.
That's the good.
The bad is that a number of examples are quite dated. For example, the book claims that Nintendo owns something like 82% of the video game market. How many years ago was this written and how would Sony and Mircrosoft respond? Intel's partnership with Gateway is mentioned in co-branding whereas the modern example would be Dell. Intel actually pays for 2/3 of Dell's advertising as part of the Intel Inside promotion.
Furthermore, the book makes no mention of Account Planning, and increasingly important field in advertising. One would think we still lived in 1992 when the Account Executive was asked to handle all strategic decicisions.
The book needs an overhaul in these ways but the essence is still very solid.
[...]
If you need to buy this textbook, buy it early, and make sure you get the CD. If you don't, send it back.
Robert the Advertising Planner.......2005-07-06
A good textbook for university students. For pro's, the book lacks a touch of ingeniuity.

Finally I begin to understand Linux.......2004-02-26
Microsoft's introduction of XP also introduced outrageous Microsoft user agreements I could never accept. Furthermore I was sick of Windows security issues, viruses, instability, and software conflicts. The GNU/Linux FREE as in freedom philosophy made sense to me, so I chose Linux FREEdom over Mac's wanna-be a monopoly world. A copy of Mandrake Linux sat on my shelf awaiting a Linux guru to help me install it, until late one night when Windows irrevocably crashed in the middle of a project I had to finish before bed. In a panic I installed Linux (along with a broad suite of apps) on an old hard drive I had, recovered my files from the Windows drive, and was working on my project again within 45 minutes. That was more than two years ago and I never looked back. I have a fast, stable, secure, virus free operating system with more and better apps than I could afford with Windows.
However, until a month ago, when I bought a copy of Linux System Administration, I could only use Linux as if it was Windows or Mac. The full power of GNU/Linux is accessible through the shell command line, and this power was beyond my grasp. It wasn't that I hadn't tried. I bough half a dozen books about Linux in order to learn how to access and use this power. But the books I bought, though highly recommended, all required prerequisite knowledge I lacked, had no logical explanation, or they were too simplistic. Nor have I been able to find anyone to hold my hand through the process of learning the real power of Linux. Linux System Administration is exactly the book I needed. Linux System Administration is not in any way dumbed down. It is simply very good at introducing and explaining Linux. This is not a beginner's book inadequate to provide any real understanding. It is a solid book suitable for use by a Linux system administratior that a beginner can begin with. Linux System Administration is empowering me to be the system administrator of my computer and LAN (and more if I want to or need to). Linux System Administration is making available to me the FREEdom, control, and power that GNU/Linux is all about.
I also recommend Linux In A Nutshell, and Linux Cookbook. Running Linux, recommended by "Linux Journal" (along with Linux System Administration and Linux In A Nutshell), had been beyond me, but maybe after I fully assimilate Linux System Administration I'll be able to make use of it.
Is it worth the hype?.......2003-05-02
Well, I picked up second edition of the book "Linux System Administration" soon after I read excellent "introductory" type of the book, "Linux for Windows Administrators" by Mark Minasi. It was a logical next step for Unix/Linux newbie like me to pick up more advanced guide for Linux SA. Now, I can only confirm that the book is worth the Linux Journal award in 2001 as being "One of the most indispensable Linux Books".
It's well written, thought technical dry and less fun to read than the book from Mr. Minasi!
The impression that I got is that book is geared more toward novices and beginners in the field of system administration (in general) than for some seasoned Unix sysadmin on her/his way to Linux. (If you're Windows admin that successfully installed Linux box or two, with solid general knowledge of the hardware than this book is for you!)
Book is organized in four parts (Basics, Managing Users and Processes, Networking and System Optimization) and as such covers most tasks and duties of Linux SA.
Layout of the book is nothing special, it's simple and with some unnecessary screenshots (like that of xrost and BRU screenshot, webmin) and lengthy scripts (such as sample netfilter startup file) - this kind of material belongs to appendix of the book.
Overall good book that you can use on a daily basis but not as a complete reference! I found book useful as a reminder of some basic principles and commands, which I later explore with the help of other books and online documentation. Have fun!
Brings the beginners to the next level..........2002-10-01
This book is perfect for the person who has been tinkering with Linux long enought to have started outgrowing the GUI based tools that the distros are spoon feeding users with.
This book takes a reader who is ready to leave webmin or other "wizard" approaches behind and wants to take the bull (er... config files) by the horns and REALLY control their machines.
The vendor/distro neutral coverage is fair and even handed, giving time to both Redhat based distros as well as Debian.
If you are itching to stop having to point and click all over the place to change a line in a config file, and are ready to learn the faster, quicker, less error prone way... here you go!
Become an SA :)
A dissapointement.......2002-07-21
This book is way too basic for anyone wanting to do anything other than just run linux. It is missing a lot that should be present, for example, setting up local caching nameservers. Perhaps this is because there are other books in the series on these topics, but if this is intended to provide a good overview, it needs to have some coverage.
I have found Advanced Linux Networking by Roderick Smith to be a better choice for information on managing linux systems.
Well Written and Current.......2002-06-21
Linux System Administration does a great job of covering a vast amount of Linux topics with just the right amount of detail for most users. This book appeals to a wide variety of readers, it is written in way that doesn't scare off newbies, but manages to have enough meat for experienced Linux users. The great thing about this book is it spends a fair amount of time explaining how to do things on a variety of distros.
Parts of the book that stand out in my mind are the chapters dealing with kernel recompilation, scripting and security. The kernel recompilation chapter is by far the best material I've seen on the subject to date, it almost makes kernel recompilation sound too easy. The security chapter is good starting point for sysadmins that are new to Linux. The book also provides a nice little introduction to scripting, although if your going to be a Linux sysadmin, the Orielly books on bash and perl are a must.
There were very few things that I didn't like about this book. One thing that stands out in my mind is the author's insistence on using paper journal books for logging system changes. With the proper backup procedures in place, a web based system log is a much more efficient way of keeping tracking of changes. Overall, the book is must read for anyone new to Linux and is also a good pickup for seasoned Linux users. I've been recommending this book over Running Linux as of late, since the Oreilly offering is showing its age.
Book Description

Khalid Sayood's textbook-style Introduction to Data Compression is the definitive guide to all kinds of compression schemes. Early chapters establish the mathematics involved in basic compression techniques, including lossless and lossy compression as well as the fundamentals of information theory that lay the groundwork for common forms of compression. (The book contains all the relevant formulas, although those who don't need such mathematical detail will still be able to understand the book.)
A good portion of the book examines various compression schemes, their strengths and weaknesses, and what content they work best for. Introduction to Data Compression begins with lossless compression schemes, which lose no information during the compression/decompression process. Huffman Coding, a well-established compression scheme, and arithmetic and dictionary coding also receive excellent treatment. In addition, the author takes on lossless compression for images.
For lossy compression, Sayood discusses schemes that use quantization, where a range of values is compressed in some way. He also describes scalar, vector, and differential encoding and fractal compression. A final chapter looks at video encryption (which often combines techniques from earlier chapters). Many of the compression schemes include examples from image and sound files, but the book considers a wide variety of video schemes too. This rich and confidently written text collates a lot of research and can serve as both textbook and source for designers who need a readable and mathematically solid introduction to data compression.
Book Description
The second edition of Introduction to Data Compression builds on the features that made the first the logical choice-for practitioners who need a comprehensive guide to compression for all types of multimedia and instructors who want to equip their students with solid foundations in these increasingly important and diverse techniques.
This book provides an extensive introduction to the theory underlying today's compression techniques, with detailed, instruction for their application. All of the coverage has been updated to reflect the state of the art in data compression, including both new algorithms and older methods for which new uses are being found. And the downloadable software gives you the opportunity to see firsthand how various algorithms work, to choose and implement appropriate techniques in your own applications, and to build your own algorithms.
* Fully updated to cover the most recent lossy and lossless compression techniques, including wavelets, subband coding, predictive lossless techniques, and Huffman coding variants.

Accessible textbook on compression does not sacrifice rigor .......2007-05-19
This is one of those books that only gets a new edition when the author has something genuinely new to say, and this third edition of Sayood's excellent introduction to data compression is no exception. This particular edition is different from the second mainly in that there is a new chapter on audio compression that includes a description of the mp3 algorithm. Also there is additional information on the new video coding standards as well as the new facsimile standards.
As to the target audience for this book, if you are tasked with designing hardware or software implementations of data compression algorithms and you have some background in either electrical engineering or computer science, then this is a good book from which to learn and then to practice what you learn via some very good exercises. Some prior knowledge of information theory and random processes wouldn't hurt either. There is also an abundance of examples that are sprinkled throughout the book to illustrate concepts as they are presented. The author's approach in each chapter is to explain each concept in as an accessible manor as possible, present relevant equations, and then work an example using what has just been presented.
The book presents the mathematical preliminaries in chapter 2, and chapters 3 and 4 are dedicated to coding algorithms which include Huffman coding, arithmetic coding, Golumb-Rice codes, and Tunstall codes. Chapters 5 and 6 describe many of the popular lossless compression methods and their applications. These methods include LZW, BWT, and DMC. Chapter 7 describes various lossless image compression algorithms such as JBIG as well as their applications. Chapter 8 discusses the mathematical background of lossy compression standards. Chapters 9 and 10 concentrate on quantization since it is the basis of most lossy compression schemes. Chapter 11 discusses differential encoding techniques such as DPCM and delta modulation. Included is a discussion of the CCITT G.726 standard.
Chapter 12 is the third and final chapter dedicated to mathematical foundations. It is meant to prepare the reader for the chapters on transform, subband, and wavelet based methods that encompass the following three chapters. The JPEG standard is covered in chapter 13, the CCITT G.722 standard in chapter 14, and the EZW, SPIHT, and JPEG2000 standards are covered in chapter 15. Chapter 16 focuses on audio compression and includes descriptions of the various MPEG audio compression schemes including mp3. Chapter 17 switches gears somewhat and covers techniques in which the data to be compressed is analyzed and a model is produced. This model is then used to synthesize the data and is quite useful in speech compression. Chapter 18 deals with video compression and diverges from the book's central theme of dealing with techniques rather than applications. The chapter discusses the H.261 standard as well as MPEG-1, MPEG-2, and MPEG-4 standards.
The website for the book, found at the publisher's site, contains a large number of C programs dealing with compression. I haven't tried to use any of these yet, so I can't speak to their validity.
A great textbook.......2006-02-11
This book has all the ingredients for a great textbook. It provides good theoratical background without going into unnecessary details, gives lot of discussion about applications, provides great exercise problems, and above all it has outstanding examples that makes some of the difficult concepts easy to understand.
Data compression needs a lot of background in information theory and other areas specific to speech, image processing etc. It is impossible to give a rigourous theoratical treatment of all of those in one volume. A strong point of this book is that it gives you just enough background on a variety of topics - without making the whole book obscure. In that respect, it is very application and implementation oriented. It is in fact what it says it is: A very good "INTRODUCTION to Data Compression"
Very good coverage.......2004-12-27
The best thing about this book is the coverage and organization of the material. Sayood covers a wide variety of compression topics without getting into the nitty gritty details of them all. Thats why its an "Introductory" book. This book is a valuable resource for those who want to know the basics of various compression techniques and can be used as a starting point for further details. Some topics like arithmetic coding are covered in more detail than others. The book is also organized nicely with mathematical foundations provided as and when necessary.
"The" Definitive Guide.......2004-02-16
Amazon claims that this is "the definitive guide". I have to agree with them because this book is the only broad grey pages introduction to data compression that I have been able to find, and it is very well written.
If you are only casually interested in data compression this book is not for you.
If you are interested in adding compression to your application and your data falls into a common category, sound, video, text ect this book is probably not for you. You should look to the open source community or buy an off the shelf product.
But if your data is odd or unique like say telemtry data (I'm sure there are other examples I just can't think of any) and you need to design a compression scheme for your data this book is "the only" book for you.
If you want to begin research into data compression and you are a newbie this book is a must have.
Very well-written book, software not so good.......2003-04-25
The book is one of the clearest I have read as a text book. Why cant everybody write like this?? There is very good flow throughout the text.
Only complaint is the software. It looks the software has not kept pace with the book itself. Some additional software has to be added (for Transform coding, for instance), and some references in the text book to the software are incorrect. If the accompanying software is upgraded, as it should be, I will rate this book a clear 5-star.

Managin Across Cultures.......2007-02-19
The book was received in good decision and within the time promised of two days.
expand your horizon.......2006-03-15
This book is great for those who are interested in comparative management. I liked it a lot and it was very useful for me because it provides lots of concrete examples of different management styles of various cultures. It made me understand and overcome some of my prejudices regarding different cultures of which I had created a certain image and it made me realize that most of the times what we assume about a different culture is wrong. It was a good read and I will certainly think twice from now on before judging people who think differently than me.
Managing Across Cultures.......2000-06-25
Susan C. Schneider and Jean-Louis Barsoux do an outstanding job of covering a very complex subject. Their extremely comprehensive chapters will please the researcher and manager alike. They are well written, avoiding academic jargon, while at the same time providing all the references a reader wanting more information on any topic may need.
The three sections of the book are logically laid out. Part one gives necessary background on the meaning of Culture. First, it debunks a dangerous assumption: that business is business and cultures are converging, thus reducing the need for cultural sophistication on the part of a manager. They clearly demonstrate that Cultural differences are alive and well and have a significant impact on business. Then they go on to discuss different cultural dimensions and how countries differ from, or are similar to, each other along them.
In Part 2 of the book the authors demonstrate how Culture affects the organization, its strategy and human resource management practices. This is must reading for strategists and HR managers and anyone who wants to have a big picture understanding of the interaction of culture & business.
The final Part of the book focuses on the actual management of cultural differences. It was my favorite. Particularly, the chapters devoted to the 'international manager' and the 'multicultural team'. I have read extensively on the two topics and was very impressed by the depth and breadth of the discussion and the authors' ability to address all the relevant issues of two complex topics briefly and clearly. I found these chapters an extremely valuable overview of what we know on both topics.
The book ends with an overview of organization strategies for managing cultures differences: ignore, minimize, or utilize. The material in this chapter is equally applicable to global cultural differences and to domestic management of diversity. The authors wrap up the book with a coherent discussion of business ethics and social responsibility in a global-economy.
An excellent book. I recommend it highly to anyone doing international work today. (Which is practically everyone...)

A career builder for me!.......2001-04-06
Like most people, public speaking was not a skill I was very comfortable with. Micki Holliday's work has added a new dimension to my technical career. I find it easier and more enjoyable as a public speaker. I now travel world-wide and get paid for literally talking to thousands of people about what I love to do!
It's working.......2000-07-23
After suffering through several presentations and wishing I wouldn't have stop just to catch my breath from fear I decided to purchase this book and attempt to correct my problem. I found that the book helped me to be more familiar with my material and use my organization skills to help clam me down ..It totally worked.
