About Prentice Hall Professional Technical Reference

With origins reaching back to the industry's first computer science publishing program in the 1960s, and formally launched as its own imprint in 1986, Prentice Hall Professional Technical Reference (PH PTR) has developed into the leading provider of technical books in the world today. Our editors now publish over 200 books annually, authored by leaders in the fields of computing, engineering, and business.

Our roots are firmly planted in the soil that gave rise to the technical revolution. Our bookshelf contains many of the industry's computing and engineering classics: Kernighan and Ritchie's C Programming Language , Nemeth's UNIX System Adminstration Handbook , Horstmann's Core Java , and Johnson's High-Speed Digital Design .

PH PTR acknowledges its auspicious beginnings while it looks to the future for inspiration. We continue to evolve and break new ground in publishing by providing today's professionals with tomorrow's solutions.

About the Cover Art

On June 28, 1778, two years after American Independence had been declared, a young woman made her way through the sweltering heat of a Revolutionary battlefield carrying pitchers of water to heat-weakened men. Mary Ludwig Hays"Molly Pitcher," as she was calledlooked up to see that one of the men who had fallen from heatstroke was her own husband, John. She resolutely made her way to his cannon just as an officer was preparing to order it retired for want of a gunner. Setting down her pitchers, Molly picked up the ramrod and took her husband's place at the muzzle.

The story of the woman gunner was told and retold by the soldiers of the Revolution, and "Molly Pitcher" became a legend around battlefield campfires. She came to symbolize all of the women who took up arms for American Independence.

During the war, General George Washington made Mary Hays a sergeant, and afterward she was pensioned as a lieutenant by the Continental Army. Mary Hays lived into her 70s and is buried in Carlisle, PA.

Foreword

Writing a book is hard writing a good book is very hard, and describing an area as complex as CIFS is a nightmare. The biggest pleasure of being involved with the production of this reference is in the clarity and depth of the end result the impossible has been achieved, for the benefit of all involved in this protocol.

CIFS is an important protocol indeed, in Windows networks it could be considered as important as TCP/IP, as almost all communication between Windows machines can flow over it. It provides file and print services, and, among other things, is a carrier for Remote Procedure Call and NT Domain services. When I came to CIFS in 2001, it was out of an interest in the Samba project an Open Source implementation that I was running on Linux where I soon became a specialist in Authentication. At the time, there was little good documentation available, particularly on the murky details of authentication.

For that reason, you will find my name scattered all over the Authentication area of this book. As a developer of a CIFS implementation, there are many things that I now know and needed to know then that were never clearly written down. Too often, the only reference on some functionality was the C code that implemented it and the implicit hope that comments vaguely represented reality. I personally spent many hours inspecting the publicly available sources of Samba and Samba-TNG, in the hope of gleaning some extra understanding, some critical detail.

My role in this book was one of many willing victims exposing all I knew about CIFS, realising how little we had all actually proved, and how much we just assumed. Chris' role was that of interrogator asking all the difficult questions, and forcing us all to re-evaluate. The end result was a lot of testing, experimentation, and analysis, but also the solid research foundation behind this massive effort.

My hope is that with this book, future developers will no longer be required to pore over cryptic standards drafts or badly commented C code to understand the "big picture" into which their software sits.

More remarkably however, Implementing CIFS provides a solid technical reference on the protocol as a whole between the standardese of the SNIA Technical Reference included as an appendix and the clear English of Chris' own chapters is a wealth of technical information that aids even the most experienced developer.

Beyond that, by creating such readable documentation, Implementing CIFS allows more than blind faith in vendors words CIFS is now assessable to network administrators and other non-programmers who can understand for themselves how this protocol works (and how it doesn't).

By leading readers though the creation of his own basic CIFS client, Chris Hertel ensures that readers have a solid background in the basics and can continue on to implementing the rest of the protocol sure of their foundations.

I've very much enjoyed working with Chris Hertel on Implementing CIFS finally, I could see a description of this protocol that mere mortals could not only understand, but also enjoy!
