Time Management for System Administrators Review

Time Management for System Administrators
Average Reviews:

(More customer reviews)
To save everyone the trouble, I'll make the obvious joke: "I bought a book on time management, but I haven't had time to read it..."
Tom Limoncelli knows this about you. He knows a lot about you. He's encountered, and found solutions for, just about every one of the paradoxes, dilemmas, Catch-22s, and neverending Sisyphean ordeals that comprise the day-to-day challenge of being a professional system administrator. He wrote (with Christine Hogan) The Practice of System and Network Administration, which presents a thorough and practical body of knowledge for IT professionals: it describes all the things you need to do to build and run a manageable infrastructure. Now he's written an equally practical book on how to actually get those things done, and he wrote it in a way that makes it palatable for system administrators -- a famously cynical bunch when it comes to books about personal productivity. And there's a lot to be cynical about...
Here's how "The Seven Habits of Highly Effective People", by Stephen Covey, begins:
In more than 25 years of working with people in business,
university, and marriage and family settings, I have come in
contact with many individuals who have achieved an incredible
degree of outward success, but have found themselves struggling
with an inner hunger, a deep need for personal congruency and
effectiveness and for healthy, growing relationships with other
people.
Deep need for personal congruency? The only deep need I feel at the moment involves my gag reflex, and not in a good way.
In comparison, here's how Tom begins:
Wait! Before we get started, let's do something to make sure we
actually finish. I realize that as a system administrator, you
are flooded with constant interruptions. The phone rings, a
customer stops by with questions, your email reader beeps with
the arrival of a new message, and someone on Instant Messenger
is trying to raise your attention. Heck, I bet someone's
interrupted you while reading this paragraph. I'm not going to
cover how to deal with interruptions until the next chapter, and
I hope you don't take offense, but at this rate, I'm worried you
won't get that far. To mitigate this problem I'm going to share
a tip from Chapter 2, which, if you implement, will shield you
from interruptions between now and when we can deal with the
subject of interruptions properly.
This book is for system administrators.
Much of the geek community has embraced David Allen's Getting Things Done as a purely pragmatic way to, well, get things done, and Tom's book complements GTD in two ways. First, Tom describes his own personal system in the space of a couple of chapters, for those who aren't interested in drinking the GTD Kool-Aid but still need to start using a system. Second, Time Management for System Administrators is totally system-agnostic -- whether you use a PDA or index cards, just about every chapter of the book will amplify the effectiveness of your existing system. He also tells you how to get into Disneyland and ride all the rides without waiting in line, and how to minimize the time you spend walking around the video store looking for something to rent.
Anyway, I need to cut this short; I'm supposed to be packing for a trip to a weeklong conference, and my girlfriend just called to remind me that we were supposed to see a movie tonight, and -- well, you know.
Incidentally, anyone who runs computers for a living should also own, read, and re-read The Practice of System and Network Administration. Buy it now if you haven't already. Also buy it for your staff, your peers, and your boss. If you don't have time to do that now, add it to your to-do list. You do have a to-do list, don't you?

Network Management: Principles and Practice Review

Network Management: Principles and Practice
Average Reviews:

(More customer reviews)
I bought this book with great hope. I have spent the past 12 odd years of my career working on various networking protocols. But, I had never worked on network management systems. I figured I could use a good book about network management. Looking at the TOC and the author's info (the author teaches at GaTech), I figured I wouldn't go wrong if I read this book.
The author definitely covers a lot of ground. The emphasis is squarely on SNMP based systems. The author also has some decent discussion about EMS/NMS, event-correlation, commercial and open-source management systems, etc.
So, why am I giving it 2*-s? I didn't like the book because it is very hard to read. The sentences are very difficult to read and understand. You have to make a big effort to figure out what the author is saying and even then, it's not easy. I am hoping the author and the editors simplify the language of the book and update some of the content in the next edition. So, my suggestion would be: wait till the next edition if you can, else, be ready to put in a lot of time into reading this book.

Network Management: Principles and Practice provides a balance of theoretical backgrounds and practical aspects of network management. Unlike other books that talk only about specific network technologies, Mani Subramanian lays the foundation for network management by presenting the background, the technologies, and the tools that all network managers simply must know. He does this by breaking the book down into three parts:*Part I provides a background on networking and network technologies such as hubs, routers, bridges, and switches. *Part II addresses network management architectures and protocols before moving on to discuss SNMP management, broadband management, and TMN. *Part III focuses on tools to monitor network parameters, network management applications, and solutions to manage networks and systems. Throughout the book, the author intertwines real-world examples based upon his experience in managing, engineering, and operating networks. 0201357429B04062001

The Practice of System and Network Administration, Second Edition Review

The Practice of System and Network Administration, Second Edition
Average Reviews:

(More customer reviews)
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.
