Thomas Limoncelli (Author), Christina Hogan (Author), Strata Chalup (Author)

Book Description

Publication Date: July 15, 2007 | ISBN-10: 0321492668 | ISBN-13: 978-0321492661 | Edition: 2

The first edition of The Practice of System and Network Administration introduced a generation of system and network administrators to a modern IT methodology. Whether you use Linux, Unix, or Windows, this newly revised edition describes the essential practices previously handed down only from mentor to protégé. This wonderfully lucid, often funny cornucopia of information introduces beginners to advanced frameworks valuable for their entire career, yet is structured to help even the most advanced experts through difficult projects.

The book's four major sections build your knowledge with the foundational elements of system administration. These sections guide you through better techniques for upgrades and change management, catalog best practices for IT services, and explore various management topics. Chapters are divided into The Basics and The Icing. When you get the Basics right it makes every other aspect of the job easier--such as automating the right things first. The Icing sections contain all the powerful things that can be done on top of the basics to wow customers and managers.

Inside, you'll find advice on topics such as

• The key elements your networks and systems need in order to make all other services run better
• Building and running reliable, scalable services, including web, storage, email, printing, and remote access
• Creating and enforcing security policies
• Upgrading multiple hosts at one time without creating havoc
• Planning for and performing flawless scheduled maintenance windows
• Managing superior helpdesks and customer care
• Avoiding the "temporary fix" trap
• Building data centers that improve server uptime
• Designing networks for speed and reliability
• Web scaling and security issues
• Why building a backup system isn't about backups
• Monitoring what you have and predicting what you will need
• How technically oriented workers can maintain their job's technical focus (and avoid an unwanted management role)
• Technical management issues, including morale, organization building, coaching, and maintaining positive visibility
• Personal skill techniques, including secrets for getting more done each day, ethical dilemmas, managing your boss, and loving your job
• System administration salary negotiation

It's no wonder the first edition received Usenix SAGE's 2005 Outstanding Achievement Award!

This eagerly anticipated second edition updates this time-proven classic:

• Chapters reordered for easier navigation
• Thousands of updates and clarifications based on reader feedback
• Plus three entirely new chapters: Web Services, Data Storage, and Documentation

5.0 out of 5 stars Moving from "Good" to "Great" in your sysadmin career April 6, 2002

By Melissa D. Binde

Format:Paperback

Good sysadmins know the technical details. They can resurrect a dead server, understand the intricacies of sendmail or the Windows registry, and recite all of the types of DNS records by heart. They own copies of the UNIX System Administration Handbook and refer to them regularly. They are good sysadmins, and will contribute solidly at an intermediate level.

Great sysadmins know all of that and what is in this book. They are the ones who go on to become the senior sysadmins and consultants, have fabulous careers, and are respected by their bosses, co-workers, and customers.

There is much more to a technical job than simply the technical skills. Don't buy this book to learn how to run a system or you will be disappointed. Do, however, buy it to learn how to be an effective professional systems administrator.

It is also useful for a manager of sysadmins who is either non-technical, or has never been a sysadmin himself, as it is a good introduction to the issues and concerns that sysadmins need to face.

Limoncelli and Hogan cover many topics, including:

- Trouble ticket systems
- Desktops and Servers (how they're the same, differ, etc.)
- Administrative networks (why bother?)
- Requirements (gathering, tracking, etc.)
- Standards and centralization of services
- How to do debugging (not "you see this problem, do this" but rather learning the process of doing good debugging)
- Fix things once, not over and over again
- Security policies (including management and organizational issues for a variety of organizational profiles)
- Disaster Recovery (again, not how to backup data, but why you'd want to, legal issues, etc.)
- Systems Administration Ethics
- Change management and revision control
- Maintenance windows: what they are and why they're good for both you and your users
- Centralization versus Decentralization
- Helpdesks: sizing, scope, processes, escalation, etc.
- Data centers (many physical facility concerns that sysadmins don't often think of, including how to move a datacenter)
- Managing non-OS software (commercial and free)

They will help you answer questions like

- Does server hardware really cost more? Do we go with a few expensive servers or many cheap ones?
- What does "redundancy" actually mean?
- Why would we spend money on backups? There's never been an outage...
- What do I do when asked to do something illegal?
- How do I communicate and schedule large system changes?
- How do I do a safe server upgrade?
- They want to decentralize the sysadmin group -- what do we do?
- How do we move our datacenter?
- What sort of policy issues are there with email?
- How do I deal with my customers abusing printers?
- What do we have to worry about if we're implementing remote access (e.g. dialup modem banks) for our users?

Finally, they close with an entire section on Management:

- How to deal with cost centers, management chains, hiring, customer support, and outsourcing.
- How to manage your customers perceptions and your team's visibility
- How to manage your own happiness (time management, communication, professional development, managing your manager, etc.)
- How to be a technical manager, how to work with non-technical managers, manage your own career growth, etc.
- How to hire good sysadmins, recruiting, interviewing, soft skills, technical skills, employee retention, etc.
- The special concerns around how to fire sysadmins (often problematic, given their higher level of access)

They even have a chapter for non-technical managers who are in charge of sysadmins (this entire book would be very useful to give to a non-technical manager who doesn't really 'get it'.)

The book closes with three appendixes:

A. The Many Role of a System Administrator
B. What to Do When...
C. Acronyms

Appendix B is particularly useful, answering a wide variety of questions with solid, practical answers.

The skills and concepts in this book are the make-or-break in many careers. They turn you from just another sysadmin into a star performer, sensitive to your customers and the business, able to interact with a wide spectrum of people.

5.0 out of 5 stars A must have for any sysadmin, regardless of skill level November 18, 2001

By Amy Rich

Format:Paperback

As a UNIX sysadmin veteran, I wish this book had been around when I started out. It would have saved so many headaches as I "learned the hard way."

Though not a nitty gritty technical book, this one is a must have for every sysadmin, regardless of skill level or the technology s/he uses. For the novice admin, it offers a good big picture look at the most important "whys" of system administration. For the intermediate admin, it has great advice on how to balance fire fighting with project work that will lessen the need for the fire fighting. For the senior admin, there are gems of design wisdom and sections on how to deal with being in a managerial or team leader role. Because it's more high level, this book is even a good buy for people who manage sysadmins but are not themselves technical.

The chapters are conveniently split into the "basics" and the "icing," depending on the skill of the reader and the state of the reader's work environment. The authors back up their sound advice with real world case studies and personal experiences. Best of all, not only was it a good read cover to cover, it's organized so that the reader can come back to it as a reference later.

Kudos to Tom and Christine for writing an excellent book, one which I will certainly be recommending to my clients and colleagues!

5.0 out of 5 stars A Mentor in a Book August 29, 2004

By Dale Dellinger

Format:Paperback|Amazon Verified Purchase

The book market is flooded with books that will tell you all about the technical details of administering various software products and operating systems. Their scope is usually limited to whatever technical product is being written about and they become outdated as quickly as the technology becomes outdated. This book is very different. It gives guidelines in a very readable, coaching style, that can be applied to many different aspects of the System Administration trade.

I have been a System Administrator for a few years now, but this book clarifies many of the issues that I work with daily. It's like a having a mentor on my bookshelf that I can pull down and consult for advice. I especially like the whole section of seven chapters dealing with different aspects of management. These chapters should be mandatory reading for every SA -- and their bosses.

The book is written in a very readable style and has many useful and insightful real-world examples that show that the authors have been around and learned a lot on the way. The book is worth reading just for these examples. I read the book from cover to cover.

I first heard about this book when I attended a seminar Tom Limoncelli taught at the 2003 LISA conference titled "Time Management for System Administrators: How to Keep from Going (More) Crazy". Many of the topics in the seminar are covered in detail in the book.

If you're a system administrator, you should read this book.
