Time Management for System Administrators - Chapter Three

February 27th, 2006 neteng

After a much needed vacation, I’m back to work and ready to take on chapter three!

The key principle behind this chapter is about the need for good routines.

I’d first like to point out routines that I’ve developed and that I feel have helped me take control of my time (in no specific order):

- Check email alerts and monitoring software in the morning

I always make this a top priority in the morning, in order to make sure that there are no outstanding issues left over from the middle of the night. I don’t want to be stuck giving my boss the lame excuse of, “I was organizing my day,” when an emergency situation presented itself and could have been resolved much quicker. Though an emergency such as this is rare, as I would normally receive a page from our network operations center, it’s always best to make sure it never happens. :)

- Always carry your organizer

Make sure that your personal organizer is within reach at all times. Whether this means you need to keep it within arms reach or in your car, that depends on you. This is good because it makes sure that you keep up the routine I previously discussed of always writing down the small things.

- Keep up with your family, friends and your professional network

I’ve found that I can keep a decent social life going if I make sure not to let it slip by the wayside in the face of a busy career. Schedule some time to converse and get together with your friends. Don’t let the good times slip by because you’re just too busy. Also, be sure to do the same with your professional contacts. You never know when you can help them out or they can help you out. Don’t be that guy who calls up an old coworker he hasn’t spoken to in years to see if he can help find him work, only to have the old coworker end the conversation with, “Who was this again?”

- Take care of those necessary errands on the weekend

Many times, I’ve found myself late for work or cutting a lunch short because I needed to fuel up my car or deposit/withdraw money from the bank. You can save yourself some time by taking care of these things during the weekend or even after work if you have time.

- “Clean house” at beginning of each month

I really, really like to have a clean apartment. My problem is, I’m lazy. I love the end result of cleaning, but it usually takes a minor miracle to have me even begin the process. I’ve found that if I schedule a couple of hours on the first weekend of each month, I can keep my place looking good with minimal effort. Having developed the routine of keeping it as clean as possible has also cut down on the amount of time I need to really clean. Not only does this apply to your home, but make sure your work environment is as clean as it could be too.

- Set aside time to work on personal items

As work-oriented as the idea of time management seems, it can do a whole lot more for you if you carry over the practices into your personal life. Always schedule some time in your off-work hours to tackle some of those hobbies and personal projects you’ve really been wanting to get your hands around. Even schedule some time to watch that DVD gathering dust and that book with the pages turning yellow from old age. If you’re like me, you’ll find yourself more fulfilled by knowing you’ve done your best to maximize “you time.”

- Go over and modify your list of major goals

The idea of maintaining a list of long-term goals is tackled in another chapter, but I’ve included it here so that you’ll see it’s very important to make it a living, breathing document. People change and their goals evolve alongside, so it’s a good idea to occasionally make sure you’re heading in the direction you want to go, which might not always be down the path you initially started.

- Take a routine mini-vacation

This is along the lines of scheduling personal items, but I really want to make sure that you take a well-deserved break from the world. It’s vital that you take some time to recharge your batteries on a regular basis so you don’t get burned out at work. No one likes a grumpy coworker and that’s exactly what you’ll be if you’re a big ball of stress, rolling around the office.


Okay, now that I’ve given you a pretty sizeable list of good habits, I’ll lay down a couple of bad habits to avoid:

- Manually patching an ongoing issue

If you’re constantly fixing a problem by hand, you’re not being a very good systems administrator. We live in a world of automation, so if you’re unable to find a resolution to a reoccurring problem for whatever reason (undocumented bug, lack of management support for permanent fix, etc.), find a way to take care of it that doesn’t need your constant intervention. Write a script, delegate a procedure…do whatever will take the issue away from your busy schedule and give you time to focus on the things you can fix.

- Going through your email first thing in the morning

Please, oh please, don’t fall into the trap of, “I’ll just browse my inbox this morning and see what’s waiting for me… Oh look, this looks like a miniscule problem that I can just fix really quickly.” … two hours pass … “Man, glad I got that issue fixed. It turned out to be a bigger problem then I thought. I know it wasn’t urgent, but it’s been fixed now.” All the while, major issues that might have been repaired in the same amount of time have grown in urgency and your boss is sweating bullets, thereby effectively making you sweat bullets. You should be organizing and planning your day with what you know, and then check your email to see what else might need to be included. Find action items and find a way to fit them in your schedule. This way, you might catch that high priority item before you take on the “would-be-nice” items.


The last step, and one of the most important, is a simple act of recursiveness. Set up a routine to address your routines and make any necessary modifications. You might need to add some things to the list, delete some things, or just change the way current problems are resolved. Over time, you’ll begin to see a pattern as to the types of items that stay on your radar and sometimes you’ll suprise yourself and discover you’re still performing tasks that are unncessary, whether due to technology, upgrades, etc.

I would love to see some more tips in the comments section if you have any to contribute! As always, feedback is greatly appreciated.

Thanks,

Vacation Time

February 23rd, 2006 neteng

I will be away from a PC until next Monday, so for those that are hungry for more time management information, I wanted to post some links of sites that I find beneficial:

Remember the Milk - I’ve just discovered this site and it seems to have some powerful tools for scheduling your life. I really only use it to send text messages to my cell phone since I don’t use a PDA that can easily alert me, but it can certainly do a whole lot more.

Lifehacker.com - This site doesn’t just have information on time management but contains all sorts of other cool stuff that us geeks love. Take control of many different aspects of your life with the information you’ll find here.

43Folders - They seem to be pretty Mac-centric, but they do have good links.

Please, post some in the comments section if you have more to share.

Have a nice weekend everyone! I know I will, email free and everything. :)

Time Management for System Administrators - Chapter Two

February 21st, 2006 neteng

Good news folks! My manager has finally returned the book into my safe keeping and I can carry on with the review. I can see this happening a lot in the future, so I think I will take Thomas’ advice and get myself a digital subscription via O’Reilly’s Safari program. Also good news is the fact that my manager loved the book and hopefully will ask our director to put a copy on every desk in our technical operations department.

Onto the task at hand…

This chapter deals with the need to maintain focus in the face of “Can I ask you a quick question?” and “I have an emergency, please stop whatever you’re doing and come take a look at this dead pixel on my monitor!” Ok, that was a bit facetious. We are all interrupted time to time by real emergencies, so we need a method of dealing with all kinds of disruptions.

As previously discussed, interruptions create the opportunity for error, and errors are bad. They cost time and money, two things in this world that we always wish we had more of!

Focused Mind

The first step to honing your focus is to begin eliminating superfluous information from your brain and start entering it into your central database. This is emphasized by the popular story of Albert Einstein once being asked for his phone number and with him replying something along the lines of, “I don’t know, check your local phone book.” Whether this is a true story or not, it certainly hammers home the point of letting trivial things be remembered by something other than your brain. Now this isn’t something that requires you to complete a few steps and then say you’re done. It’s an ongoing process and if you’re anything like me, it will take time and a lot of willpower to make it happen. There will be times when you say, “Oh, I’d have to be a complete idiot to forget that…” and then you will eventually follow that with “Man, I am a complete idiot!” Trust me, just write…it…down…

Environment

This portion of the chapter cannot be pressed upon enough! I used to get this sudden feeling of dread whenever I’d walk into my cubicle in the morning and find sticky notes and loose pieces of paper lying about. Some of these items held important bits of information, others contained things I hadn’t needed for a few weeks. It’s your job, as a new member of the Time Management MilitiaTM (I’m trademarking that baby!), to get rid of that clutter and allow yourself to maintain concentration.

Thomas suggests filing what you can, keeping your unfinished items in a single to-do stack and putting the rest in an envelope that you promise to throw away if you haven’t opened it in three months. That’s not too difficult, right? Believe me, you will find yourself with very little in that envelope if you centralize your information database and cut back on the amount of multitasking you attempt.

The need for a clean working environment also holds for your virtual desktop, so make sure to get rid of those unnecessary icons and files, only use IM & email when necessary and you might even have to disable that Internet connection if you’re like me and easily tempted to check out The Onion.

Multitasking

The key ideas here are:

- Know what to multitask - Never try to handle more then one task that requires your undivided attention, or I might go so far as to say even half of your attention. You might be able to get away with flawlessly executing each task sometimes, but I have a hard time believing you’ll beat the odds in the long run. Tasks that you could get away with juggling usually involve automated processes that you can leave to perform on their own while you turn your attention elsewhere.

- Be aware of your stress level - If you feel as if you’re being attacked from all directions by people and their requests and they require your complete dedication right now, stop. Take a deep breath, step back and take another look at your priorities. You can’t please everybody all of the time, but you can certainly piss them all off by half-assing each request. :) It’s key to recognize when you’ve hit the boiling point and be able to return to a state of calm.

Peak Time for Focus

Figure out at least an hour of time during the day when there are no external interruptions. For most people, this will be in the morning. For others, it’s when the rest of the office has gone to lunch. Whenever works best for you, this is time that you could use to really focus on key projects. If everyone gets into the office at 9, come in at 8. If most of your co-workers head out for lunch at noon, take yours at 11 or 1. I’ve found that an early morning works great for me and I can also sneak in an early lunch for even more focus time.

Interruptions

If there is one thing that really grabbed me in this section, it was Thomas’ idea that we should not be interrupt driven. If we are constantly pulled away from our work for interruptions, then we are no longer in control of our jobs and that means we have little to no control over our careers. The idea here is to take control.

Customers and coworkers need to know they’ve been acknowledged. I’ve seen it through and through in my comparatively short career and it would be quite true to say that by simply acknowledging and empathizing with the customer, you can buy yourself time and respect.

To help fight these interruptions, there is really only one question you need to ask yourself at the time:

Should I delegate the task, record it for later, or just do it?

Let’s look at our options:

- Delegate – If it doesn’t require your expertise, then find someone who is better able to assist the requestor.

- Record – If it does require your expertise but is not wreaking major havoc, write it down in your central database to be resolved at another time.

- Do – If you just killed the CEO’s email connectivity, GO… NOW! Also, if it’s a small task (and make sure it really is a small task and not just masked as such) that can be completed with 1 or 2 minutes work and it’s easier to do now rather then delegate or perform at another time, do it.


Well, that’s about it for my summary on this chapter. As always, feedback is appreciated!

Thanks,

VPN - Virtual Private Network

February 17th, 2006 neteng

My manager and I have both been rather busy so it doesn’t look like I’ll get to the chapter 2 review before next week. But in the meantime, I’ve decided to throw up some information on VPNs and their uses. I could go into excruciating detail about the actual process, but why reinvent the wheel? There are lots of great resources already out there that discuss the ins and outs of this vital technology and that’s what I’m going to share with you:

http://www.howstuffworks.com/vpn.htm - One of my favorite resources for a general overview on lots of topics, HowStuffWorks.com has a great little write up on the basics of VPNs in all of their incarnations.

http://www.tcpipguide.com/free/t_IPSecurityIPSecProtocols.htm - This section of a great TCP/IP reference has lots of information on IPSec-based VPNs. It really helped me grasp the fundamentals at the heart of IPSec.

http://ipsec-wit.antd.nist.gov/ - This was a really unique tool that I stumbled across. It actually enables you to form a security association between your equipment and a NIST device. This can help troubleshoot tunnel issues to make sure your configuration conforms to the proper IETF standards.

http://nirlog.com/2006/01/23/secure-remote-access-ssl-vpn/ - My good friend Niranjan has a great article on SSL VPNs in particular. Check it out to bring yourself up to speed.

If anyone has other links or information that would be useful, please post a comment!

Thanks all,

Time Management for System Administrators - Chapter One

February 11th, 2006 neteng

Like any other decent how-to book, the first chapter explains the core principles behind the subject matter, hence the chapter title Time Management Principles. I knew I was going to really gain something from this book as soon as the author, Thomas Limoncelli, gave a tip on handling interruptions within the first few paragraphs. He really wants to make sure you finish this book. I’ll discuss the tip as I approach the commentary on that specific chapter.

Thomas asks the question, “What’s so difficult about time management?” This is where we see the book diverge from your average book on the subject. Us techie types are really a different breed in the office due in no small part to the amount of interruptions we encounter throughout the day. Sure, everyone gets pulled away every now and then for emergencies and forgotten items that were already scheduled, but I’d bet dollars to donuts that sysadmins would rank near the top of the scale for daily interruptions. It’s these very interruptions that can be hazardous to the projects and issues we were dealing with at the time. I know all too well what Thomas means when he states, “…returning to your project after an interruption can lead to errors.” When you’ve lost your train of thought in a field as technical as ours, I don’t care how much control you claim to have over your brain, it’s too easy make a typo or skip a vital step as you try to remember where you left off. With technology playing such a huge role within the business, mistakes can be pretty expensive.

The main principles that Thomas discusses are:

A single database for your time management information

I used to be (I feel kind of funny saying “used to be” since that was only 2 weeks ago) the guy that had innumerable amounts of sticky notes on his monitor, desk, laptop bag, cat, etc. Not only was it a time waster trying to find the right sticky note, but my bad handwriting only made getting the information I needed ten times more difficult. I’ve found that if I need to, I will still write something on a sticky note, but I will copy that note into my day planner at the earliest opportunity. Writing everything down in a central location has also forced me to write a bit more legibly as well, knowing that I’ll be accountable for everything I put to paper.

Conserve your brain for the important tasks

DO NOT try to remember to pick up that laundry detergent the next time you go to the market. WRITE IT DOWN IN YOUR CENTRAL DATABASE. This is probably one of the harder habits for me to get into, but I like a challenge and I think the fear of failure has forced me to really stick with it. It’s so satisfying to perform a task that you know you would have forgotten if you had not written it down and planned it out ahead of time. You also free yourself from worrying about that thing you know you have to do, if only you could remember what the hell it was! It might not bother you much to forget a single item, but you soon find yourself juggling three or four of them and that’s when the worrying starts to take it’s toll and pull you away from whatever you should be concentrating on. It’s extremely liberating to write the little things down knowing that you won’t have to worry about forgetting them.

Develop good habits

I already delved a little bit into this, but it can’t be stressed enough. Drop those bad habits and pick up some new ones that benefit you for once! Minimizing bad stress (you’ll learn a little later on that *gasp* not all stress is bad) follows naturally from developing good habits.

Maintain focus

Once again, focus is key to really managing your time as efficiently as possible. It does you absolutely no good to half-ass a task and cross it off your to-do list, only to find yourself coming back to that task to correct the error you made in the first place.

Use the same tools to manage your social life

Don’t promise your boss that you’ll work late on a special project only to find out that you also promised to take your special someone out for a nice dinner on the same night. You need to have a life outside of work or else you’ll become useless even at work. Not only does using the time management system allow you to balance your career with your life, but the system will also allow you to be more productive outside of the office. I have found that I’m able to complete a lot of the necessary ‘life things’ (housework, car maintenance, laundry, etc.) very quickly and efficiently, which leaves me a lot more time to do the things I really want to do. I’m able to look forward to some of the larger goals that I want to accomplish and plan accordingly before I’m stuck in a retirement home. I’ve always been a little self-defeating when it comes to overwhelming “big-picture” items in my life, but the tips in this book have enabled me to break up these items into manageable tasks and not be intimidated to move forward on them.


We’ve all had years to develop our bad habits and they’re not going to change overnight. But all it takes is a little willpower and a lot of desire to improve your life, and the rest will fall into place. It is my hope that you’ll take something away from this and subsequent posts. I really want to urge you to pick up the book and recommend it to anyone you feel could gain from it. Please post any comments and insights you may have along the way as I think we could all benefit from the discussion.neteng

Time Management for System Administrators

Time Management for System Administrators

I would like to take some time to share with you a book that has been a real eye-opener for me. I plan on taking a chapter-by-chapter review approach to give some insight on why this text has quickly become my new best friend, but first I wanted to give a brief overview of why I bought this book:

Anyone who knows me, knows that I am really, really, really good at procrastinating! “Oh, I’m too tired from work… I’ll clean my apartment tomorrow.”… tomorrow arrives… “Man, I’m just beat. I’ll clean my apartment on Saturday when I don’t have work fatigue!”… Saturday comes… “It’s the weekend! I don’t want to clean house during my fun time!” … a month down the road… “Hmmm, is carpet supposed to be sticky?”

The one thing I’ve really noticed since reading through this book is I’ve gained some major SELF-DISCIPLINE. And that really is the key to defeating procrastination. I really do want to be all that I can be and push myself to the limits, but you mean I actually have to work at it?! Yes, it is work and it’s not easy for me to maintain such discipline on a lot of issues. But by following the recommendations in this book, I’m forcing myself to break bad habits and form good habits.

Following this will be a summarization of the first chapter and key points. In each chapter overview, I hope to show how I’ve put the system to use. If anyone has their own system or tries some of the things recommended in my postings, please give me some feedback in the comments section. I would love to hear how others manage their time.

Networking Links

February 3rd, 2006 neteng

I thought I’d share some links to various websites that I’ve found useful when dealing with networking issues and news:

  • IP Calculator / IP Subnetting - I’m often given networking information by a customer to input into VPN configurations and I’ve found that a lot of times, the customer makes mistakes. They will give me an invalid IP address and assume it’s correct. Sure, this is easy to spot when a customer tells you to use 192.168.0.0 as an IP address on a 192.168.0.0/24 network. But it becomes much more of a pain when you’re dealing with a network such as 192.168.48.32/21. I’ve learned to calculate some of these things pretty quickly in my head with the best of them, but there’s no excuse not to check your work with this. Believe it or not, a user has slipped a broadcast address right by me and a certain brand of networking devices (*cough* SonicWall *cough*) won’t catch the error.
  • Internet Health Report - This little beauty is a fantastic reference when you’re dealing with VPN-connected customers. If you start receiving calls from multiple customers that they’re having network response issues, this is one of the first places you should be looking. Network problems are far and few with the major providers, but peering issues between these providers happens more then one thinks. I would love to be able to get more information on just how the peering works and what sort of SLAs the ISPs have with each other.
  • The TCP/IP Guide - This is the one of the coolest reference texts that I have found concerning the primary language of networking. I remember seeing this in book form at Barnes & Noble and thinking how cool it was, but the $70 they were asking for was a bit much for me. Imagine my joy when right in the beginning of the book, they tell you that it is available online for free! There is some great in-depth material here though and excellent diagrams to provide visual aids.
  • IETF RFC Page - When all else fails, go to the source. If you’re the type of person that sleeps with technical manuals underneath their pillow, this is the place for you. Raw and unadulterated, some of these are sure to bring your brain to a near meltdown! But it is cool to see a bit of history in these pages. RFC 1918 is one that all networking types are bound to come accross at some point in their career. It explains the private addressing that is used for internal networks (192.168.0.0/24, 172.31.16.0/12 and 10.0.0.0/8).

This should provide you with some excitement for the day. Don’t expend it all on one link!
