Diary of a Network Geek

That’s a long title for something only a few of my hardcore readers will be interested in.

I used to blog about a lot of hardcore geeky things, professional geeky things and personal geeky things both. But, for a while now, I’ve drifted away from some of the geekier stuff. It’s not that I have less interest, because I assure you I’m still a pretty hardcore geek. For instance, the other day, I rooted an old Android phone so I could install Kali Linux on it for some mobile penetration testing. Except, I wasn’t happy with the rooting tool I had used and how the whole thing turned out, so I wiped it and, when thing settle down a bit from the aftermath of Hurricane Harvey, I’ll take another crack it, if you’ll pardon the pun.
I’m still an IT professional, and have gotten more technical again in my most current several positions. Which really means that I have spent more time managing systems than people, which is just fine with me. And, as I just mentioned, I’ve spent some time thinking about security, which for me always includes Linux in some form or flavor. Of course, it helps that I’m an old Novell guy and picked up my CompTIA Linux+ back before they changed the requirements to include regular recertification. Now, that doesn’t mean I don’t work to keep my Linux skills sharp, just that I’m not required to for the certification.
And, that’s what inspired me to bring my fellow geeks this week’s link; The Awesome Linux Software repository at Github!
If you’re interested in Linux, this is a fantastic collection links to four of the most popular distros (Arch Linux, CentOS, openSUSE, and Ubuntu), and dozens of programs for your every Linux-based need. The maintainer, Lewis Vo, has links to Linux software for Audio, Chat Clients, Data Backup and Recovery, Desktop Customization, Development, E-Book Utilities, Editors, Email Utilities, File Managers, Games, Graphics, Internet, Office, Productivity, Security, Sharing Files, Terminal, Utilities, and Video, as well as Command Line Utilities, Desktop Environments, Display Managers, and Window Managers. I mean, there are links to EVERYTHING a Linux geek could want.

If you’ve never tried Linux, I highly recommend you do, or talk to a geek friend about it. We’re happy to talk about it for hours!
And, next week, something for a wider audience, I promise!

Naming kids is easy, but naming systems is hard!

And, no, I don’t mean giving your phone a pet name.

I have gone on at length in the past about the importance of naming systems.  It’s a big, big deal, especially if you ever have to go back and change any of those names!  Granted, it’s not as bad now as it was in the old days when you had to manually update dozens, or sometimes hundreds, of host files or configuration files, but, still, it’s a pretty big deal.  So, naming systems are often a topic of discussion, especially among hardcore network geeks.  I’ve been in more than one meeting about choosing a naming scheme that devolved into name calling.
So, there are many schools of thought on this.  One group of people think that the name should be meaningful, giving location and function information.  That’s a good idea, but it often results in names like HOUNOVFILESERV001.  (And, yes, that’s actually a name I used on a server once, for a company that no longer exists.  It stands for HOUston NOVell FILESERVer number 001.)  Sure, it tells you what you need to know, but they quickly become unwieldy to type and maintain.
Another group would say to name your servers, or routers, or what have you, after any group of things that will be easy to remember, like the names of the Seven Dwarves, or characters from the Dilbert cartoon, or, even, at one place I worked, the names of the old Space Shuttle fleet.  And, while I’m not a huge fan of that for many things at a business, it can be fun to ping a Cisco router named Elvis just to get the response “Elvis is alive”.  Certainly at home, I tend to favor a more fun approach using something light-hearted, like the names of cartoon characters or mythological beings or something similar.  But, my problem is always, which set of “things” to choose?

Well, the Naming Schemes Wiki solves that particular problem.  Yes, someone has started a wiki that gathers all the different naming schemes you all can think of in one place for your viewing pleasure.  And, in spite of any protests from your significant other, you can select, at your leisure, a naming scheme to use on your network that makes you smile.  (And, stop looking at me that way!  I know I’m not the only person in the world with a home network big enough or complicated enough to warrant having to choose a naming system for it!)  The maintainer also encourages you to add your own scheme, if, somehow, it’s been missed on this site.  Or, to add to any of the existing pages if you have something to contribute.

So there you have it!  All the endless naming possibilities for your home networking project this weekend!
Y’all have fun!

There are a lot of Linux distributions.

No, really, I mean there are literally hundreds, if not thousands, of Linux distributions out there.
Frankly, it can get a little overwhelming sometimes.  But, I think about them and what they all are and what they do.  I think about them because it’s my job, and because I’m always thinking about what’s coming next in the IT industry.  So, what Linux installs do I think about?  Funny you should ask….
I think about Android.  Yeah, that’s right, the operating system that runs those Droid phones is a kind of Linux.  That’s kind of amazing to me, really, but there it is.  And, I think about it because Android seems to be on more and more devices these days.  Everything from phones to tablets to who knows what next in the consumer market.  But, I try to pay attention to Android because so many people at my office have Android based phones and they all expect me to help them figure their phones out.
I think about Fedora, which is the open source version of Red Hat, which enjoyed pretty good market penetration when they first got going.  They’ve got a lot more competition today, but, still it’s in an IT professional’s best interests to be at least familiar with Fedora.
That goes for openSUSE, too.  openSUSE was bought out by Novell some time ago, so there’s no telling where it’s going to end up with all the buying and selling around Novell’s bits and pieces these days, but it’s still a pretty heavily installed Linux distribution.  My brief experience with it was good, though, I have to admit, that was on older hardware for a personal project, not a corporate gig.
If you’re an Oracle shop, you’ll probably know about Oracle Linux, which is basically Red Hat Linux after Oracle has made modifications to it.  Oh, and jacked the price up.  Still, if you work with Oracle a lot, it’s probably worth looking into.
Eweek recently ran a slidwshow about these, and several other, versions of Linux under the title 10 Linux Distros Every IT Manager Should Know.  Obviously, I agree with some of their listing, but clearly not all.  And, I think they left some off.

For instance, what about the live CD editions?
Two I think anyone in IT should know are Ubuntu and Knoppix.  Knoppix has been around a longer, but Ubuntu has a slicker interface and, I think, is a little better at detecting hardware than Knoppix.  Also, you can install Ubuntu from the live CD media, if you would like, and plenty of people do run it as a desktop.  The real plus is that there’s a pretty healthy community around these two installations, especially Ubuntu.  So, if you need help with either one, there are a lot of resources on the internet to answer your questions.
I use these two all the time to recover data of damaged installs of Windows.  I even used one to build a PC imaging system before I started using Clonezilla, which is also, incidentally, based on Linux.

If you’re worried about security, Linux can help with that, too.
For quite some time, the National Security Agency has sponsored SELinux, which is a pretty secure, hardened version of Linux.  They designed it to be reasonably secure right as a default, since an insecure default install is usually where security problems start.  Of course, you may not trust the NSA.  And, while this is “sponsored” by them, it’s not actually an official US Government Linux install.
For that, you have to go to the US Airforce.  Their Lightweight Portable Security distro is the first official US Linux distribution.  I haven’t actually tried it myself, but ZDNet has a pretty good review of it.

So, as you can see, if you haven’t looked into Linux much before, there are a lot of things to investigate.  And, as a computer professional, I DO recommend that you check out at least some flavor of Linux.  It’s so prevalent and so flexible and handy to have that if you haven’t bumped into it yet, you will.  So before you need to know it, investigate it some on your own.  You’ll be glad you did.
(And, I’m sure every seasoned IT pro has their favorite distro, like Debian, but there are too many to list them all.  If you have opinions about any, please, leave comments!)

   --Elbert Hubbard

No, that’s not candy.

Though, I have to admit, sometimes the industry treats them like candy!
No, I’m talking about technical certifications, which are, I think, the bane of the IT industry now.  Folks over at TechRepublic are talking about tech certs and their relative value.  Personally, I don’t think they are that valuable any more.  Oh, back in the day, I think they were and, to a degree, they solve certain problems for hiring managers, but, I don’t think they matter as much any more.  Of course, maybe that has something to do with where I am in the industry and job market, too.  I am, frighteningly enough, a seasoned professional.  So, my work history and experience count for a lot more than the handful of certifications I have.  (For the record, I’ve been Novell certified since 1994 and Linux certified since 2003.)
As far as I’m concerned, the only thing my certs are good for any more are getting past a Human Resources person acting as a firewall to the hiring manager.  Usually, if I’ve done all my homework like I should before even applying for a job, once I get to the hiring manager, I’m pretty much in.  And, honestly, they don’t normally care about my certs.  They care about my ability to execute.

So, what do you think?  Are professional certifications like this worth the paper they’re printed on any more?

Search engine marketing for job search?

Sure, why not?
I mean, that is why I started this blog ten years ago.  I guess I’m a little ahead of the curve, though, because Channel Insider just recently ran a story listing 17 tips for using SEO and social media to get the IT job you really want.  Mostly, they’re good tips, too, though for anyone who’s internet savvy at all, they’re also mostly common sense.  In fact, I think most real, good search engine optimization is just plain common sense.  Granted, I may be biased because of what I do and how I spend my free time, but, still, it’s not rocket science, you know?

I’ll grant you, this blog has wandered away from my original purpose a bit, but I still talk about technology and some of the things I do at work.  Initially, I started do this so I could drop buzzwords on my page, like “networking” and Certified Novell Engineer”, with normal language to lure in the search engines.  It was easy, really, all I had to do was bore people with detailed descriptions of the IT stuff I did all week long.  Then, because that gets boring fast, I started to occasionally pepper those entries with more colorful personal anecdotes.  Not too colorful, though!

One of the best tips is, to me, one of the most obvious, too.
Be careful what you post.  People seem to quickly forget that the search engines find everything.  Every drunken picture you post or every off-color joke or skeevy thing you share on Facebook or Twitter or anywhere else eventually will get traced back to you.  Count on it.  So, be careful to share only the important information and just the details that relate to the image you want to project to get that job.  Treat the whole exercise as an extended digital job interview and put your best foot forward.

Oh, also?  Be honest.  Don’t over-share, but don’t lie either.  The other thing you can count on is that every lie you tell on-line will eventually be found out.

Other than that, though, the real secret is to just provide good content that people want to read.  That, by its very nature, will include all the SEO keywords that you’ll need and give you all the right kinds of links, and, most importantly of all, the right kinds of readers.
Trust me.  I’m telling you this as a guy who once got a call from another city from someone looking for a Novell consultant and was hoping I could help.  Why?  Because I was the number one hit for CNE on Google and they could get to me, but they couldn’t find similar help from Novell themselves.  So, yeah, I do know what I’m talking about and it really does work.  Just do the foot-work, and be patient while the rest happens.  It will.
Trust me.

Yesterday marked this blog’s ten year anniversary.

In ten years, I’ve made more than 1,700 posts and had more than 1,900 comments, many of those from years when I blogged almost every day.  But, it was ten years ago when I uploaded my first entry. I edited it in a text editor of some kind, probably Notepad, and used FTP to push it up to the server. That was back in the days before blogging software and when most of us still called them journals or diaries. I started doing it to try and game the search engines. Mostly, it worked, I think, since the majority of my readers have found me via a search of some kind.

Since that first entry, a lot has changed.
I’ve been through two different kinds of blogging software. After months of doing it by hand, I converted to Moveable Type. I used that for several years, until the Time of the Troubles, when there was a big fuss over how Moveable Type was going to charge for previously free software, even after promising to keep it free forever. Like most converts, I changed over to WordPress, which I still use today. Moveable Type does have a free version, but, frankly, after learning how easy it was to style and customize WordPress, I can’t imagine moving back. Not to mention how much easier it is to make plugins for WordPress. Frankly, I love it.
Ten years ago, I did quite a few entries from the road via my old Palm IIIc with a folding keyboard. I typed them up and then synced that with my PC and pushed the entries from there. That old IIIc doesn’t hold a charge too well any more, but I’m still using the same PC I was ten years ago. Of course, I’ve added a much newer laptop, several other machines, and an iPhone to my technological stable since then. In fact, I was a beta tester for the new iPhone WordPress app!

A lot of other things have changed, too.
For one thing, I married and subsequently divorced the woman I was living with at the time. I’ve changed jobs, count it, five times, finally staying at my current company for about five years. I survived cancer. But, ironically, after several ups and downs with weight, I’m probably in better shape now than I was ten years ago!
Sure, I’d have liked to had a few more dates in the past ten years, but, I think I’ve done okay considering the divorce, not to mention the less than stellar marriage and, you know, the cheating death and all.  You’d be surprised how tired you get dodging the Grim Reaper!

I’ve upgraded my Novell certification at least once in that time as well as added a Linux certification.  My original plan of using this blog to boost my rankings in the search engines has largely paid off, as I’m consistently the number one or number two hit on Google for the search term “network geek”.
In that time, I’ve taught myself Perl, which is a scripting/programming language that’s been called the “duct tape of the Internet”.  In fact, as of this post, I’m a Level 8 PerlMonk.  (It’s a geek thing.) I’ve also gotten reasonably proficient at PHP, since that’s the technology which makes WordPress go.  At least, I’ve gotten good enough to write a few simple plugins and even a rough theme.  Frankly, I hope to do more of that soon, too.

I’ve taken up photography since starting this blog, too, and I think I’ve gotten fairly good at it.  Naturally, there’s room for improvement, as I’ve only been doing it for about two years, but, still, it’s something I’ve wanted to do for a long, long time.  I’m not very artistically skilled, but photography lets me tap into that in a less intimidating way.  I suppose, in a way, so does my obsession with blog themes and logo design.

And, of course, I’ve started several other blogs or websites in the ten years that I’ve had this blog.  But, don’t worry, those sites have been languishing just as badly as this one has the past several months.  It’s not that I haven’t wanted to write, or even had things to write about, but I’ve just been too busy to sit down and do it.
Though, I do have to admit, part of that sort of writer’s block has been about my audience.  I mean, if you hit that search function over in the sidebar, you can get pretty interesting access to my life for the past ten years.  Oh, sure, not everything makes it into the blog, but I’ve been pretty candid posting here.  I try to keep it clean, mostly, and nothing that would embarrass my mother, but, I have been honest enough to shock a few friends.  So, if there’s something you want to know about me, just search for it.  You may be surprised what you find here!

So, wow.
It’s been an interesting experience blogging for the past ten years.  I started before the trend was as huge as it was and kept on even when the shine had worn off for many.  I can say for sure that I didn’t anticipate many of the twists and turns this blog took over the past ten years, much less my life, but it has been an interesting ride.  Many of you have been with me for quite some time now and I appreciate you reading along with me here.
I don’t know what the next ten years will bring here, or elsewhere in life, but I do hope you’d come along for the ride.  I’m sure it will be as big a surprise to me as it is to you!

A pretty bold statement, isn’t it?

Well, I’m not going to tell you how to build the “ultimate home network”, but, rather, suggest some things that you may want to consider to build your own, personal, “ultimate” home network.  Everyone needs something different from a home or small office network.  Some of us have side jobs that require a fair amount of data transfer or storage, like, for instance photographers.  For some of us in the IT business, having a home “test” network is almost assumed, though, perhaps not as much as it used to be in the boom days of the Internet.
I’ve been thinking about it this past week because my old BorderManager firewall finally has died.  I’m using a backup firewall at the moment, which is “good enough”, but I’ll be taking this crash as an opportunity to start rebuilding my home network from the ground up, using mainly free, open source software, starting with a Linux firewall.  In fact, I have three that I’ll be looking at and, yes, writing reviews of, in the coming weeks.  This will be an on going series of posts, too, as I evaluate software and, piece by piece, integrate it into my working, live network.  My needs will probably be different than yours, but all home networks will have some similar items and considerations.
So, what should go into your own personal, “ultimate” home network?  It depends on what you do, but here are some ideas.

The Actual Network.
Obviously, the first thing is setting up the actual, physical network.  And, in this case, by physical, I’m including wifi routers and the like.  Back in the old days, having a home network meant running cable.  That’s not as true as it used to be, but don’t just go wireless without considering at least some wired connections.  If you’re concerned about security, for instance, especially, regarding financial transactions, nothing is as secure as a wired connection.  Keep in mind, though, that at some point you still connect to an outside source to get to your bank.  Also, since most laptops have built-in wifi and have gotten so inexpensive, if you don’t already have one, consider getting a laptop.  For most people, laptops can inexpensively do everything we need to do and have the advantage of portability, so if you need to leave, say in case of a hurricane, you can take at least part of your home network with you.
There are a wide range of network switches and routers out there to choose from, but I suggest sticking with a name brand that is relatively well known and established. It’s no guarantee that you won’t have problems, but it’s a good start. I personally like Linksys and DLink brands, but there are many others that will work well, too.

Security.
Don’t forget that you need to have at least some security on that home network.  At a bare minimum, you need a firewall and some kind of antivirus.  If you’re connecting to broadband internet, either cable or DSL, most often the router they give you from the service you use has a firewall on it.  If you’re using wifi, the wifi router almost certainly has a firewall on it.  Use them!  Most importantly, actually set them up and change the default password to something else that you’ll remember but that strangers won’t guess.  If you’re not sure if you have a firewall on your network equipment, then at least use the built-in Windows firewall, but use something!
If you don’t want to spend big money on either McAfee or Norton for antivirus, good news!  You don’t have to spend anything!  Yes, that’s right, you can download AVGFree and run it for nothing at all.  So, now, what excuse do you have to not be running some kind of antivirus again?
And, please, for your own sake, use passwords.  Use hard to guess passwords, not your kids names or your birthday or even your license plate number.  In fact, try not to use dictionary words at all, or, if you do, substitute other characters for letters, like $ for S or @ for A, to make it more difficult to guess.  Also, use numbers with the letters, for the same reason.

Networked Storage.
Just having storage isn’t enough, really.  On a home network now, you may have a laptop, or two, a desktop, a DVR or any number of different networked devices that share data.  They all need to store it somewhere.  And, even if they store the data locally, they need to be backed up somewhere.  The answer is network based storage.  There are a lot of options out there, and Rick Vanover at TechRepublic has a good article on several.  I know one solution that’s popular with photographers is the Data Robotics Drobo series of devices.  I don’t have any direct experience with these, so I have no opinion on them specifically, but these days, decent network attached storage is so cheap, it would be foolish to ignore that as an option.

Virtual Server Environment.
Now, obviously, this isn’t for everyone.  Back in the day, I used to run a small, two server Novell network in my house just to keep everything fresh in my mind.  Novell isn’t always the most popular networking environment, even for hard-core network geeks like me, so I always wanted to make sure I knew how to do some of the more “interesting” and challenging things in that environment and ran a test network at home for that reason.
Now, you can do all that through virtualization.  In fact, that may be the newest buzzword that’s already worn thin on me!  But, buzzword or not, setting up a virtual test network is something that’s been talked to death in the industry, but I’ve only seen one article recently on setting up a home virtual test network.  You can read more about it in an article by Brad Bird over at TechRepublic, but, again, for those of us who work in a lot of different environments, it’s not a bad idea to make a series of virtual machines to experiment on.  There are still some hardware costs involved, of course, but there is the advantage of being able to roll back to an earlier state if something gets too screwed up.  Try that on your old-fashioned home network!

Even Fancier Stuff!
Of course, there’s almost no limit to what you can do on a home network these days.  Many inexpensive printers come with network interfaces built in, some even have wifi networking built in.  Of course, I’ve mentioned things like Windows Home Server and Linux servers here before, too.  It is, after all, what I do.  Though, with the low prices on network attached storage, I’m not sure I’d recommend that option for the average user.
And, this post hasn’t even touched on integrating any audio visual equipment into your network, or a home security system, or some of the fancier bells and whistles that are out there.  The sky, literally, is the limit.

So, the thing is, everyone will have a different idea of what the “ultimate” home network is, but these are some things to consider, and a few you don’t want to forget.

Wow, maybe Novell isn’t quite dead yet after all!

According to this story at Computer World, the New York-based Elliot Associates, LP, a hedge fund that is already Novell’s largest stock-holder, has made a public bid for the company.  They claim to have extensive experience and good fortune turning around tech companies, and they see the potential in the once great Novell.

I’m not holding my breath, but I hope it works.
It’d be nice to see a company like Novell get turned around.  Their products consistently win awards, but their marketing never seems to get them where they need to be.  Novell basically started the local area network market, but now they’re very much the “also ran” in that category, coming in far, far behind Microsoft.
Again, I’m not holding my breath here, but I hope they can do it.

So, I’ve been thinking about getting yet another professional certification.

I’ve been a Certified Novell Engineer for about fifteen years now.  In fact, I upgraded that cert three times after initially certifying back in 1993.  In 2003, I got the CompTIA Linux+ certification.  All at more or less my own expense.  Now, I haven’t heard anything about Novell updating their certification requirements lately, but I suppose it might happen one day.  I don’t think I’ll pay to re-up that cert, though.  I haven’t really used Novell in any significant sense for about five years now, so there’s not much point in maintaining it.
The lack of continuing education requirement is one of the things I liked about getting the CompTIA Linux+ certification.  One test, one cert, for life.  It seemed like a good idea to me, a good investment.  About the time I ended up getting divorced, I gave up on studying for the CompTIA Security+ certification.  There seemed plenty of time.  Well, as it turns out, there may not be after all.

Earlier this year, CompTIA announced that there would be continuing education requirements for several of their certifications.  Well, the great mass of IT professionals raised such a hue and cry about it that they modified that stance somewhat.  We not have until the end of this year to get the certifications if we want to escape the re-up requirements.  That goes for the A+, the Network+ and, yes, the Security+ certifications.
So, it looks like I’ll be buying the Exam Cram Security+ book and, probably, investing in the SelfTest Software pre-exam study software, too.  It’s not that big an investment monetarily, but I suspect it will be a little more difficult to knuckle down and study to take the test.  I haven’t worked at that sort of thing for quite some time now, and I’m almost afraid I’ve forgotten how!

Of course, the real question is, in a way, whether or not it’s even worth getting the certification at all.  I mean, it just sucks me even deeper into the bottomless pit that is the IT profession.  It’s a never-ending treadmill of oppressive hours and thankless work that few people truly appreciate.  Of course, it does pay pretty well.  And, it does beat digging ditches.  Most days.
Naturally, my hope is that the Security+ certification will make me more marketable in the long-term, should something happen to my current job.  Not that I think that’s likely, but still, it never hurts to be prepared.  And, frankly, security is going to continue to be a big issue going forward, so getting this particular certification surely can’t hurt my resume any.

Over all, the investment is small for the potential return.  And, it will probably do me good to stretch my poor, feeble, little mind to work at something like this again.
Besides, I may know a beautiful, young college student or two who could help me study.
Stranger things have happened!

It seems like this comes around on a regular basis.

Server names and naming conventions are a constant source of argument and irritation in big IT departments.  Everyone has their own idea of just what naming schema should be used for the servers and workstations and such on the network.  And, since it hasn’t shown up recently on Slashdot, we were about due for an article on it.  There is; Why do we name servers the way we do?  The comments, if you can be bothered to dig down deep into them and wade past some of the worst attempts at humor, are quite telling.  It doesn’t take long before the relative merits of using quirky, easy to remember names is being quite hotly debated.

The original article  over at IT World, titled Would a server by any other name be as functional?, seems to weigh in on the side of the more creative names.
I’ve worked both kinds of places, actually.  In one job, we used a very precise naming convention that had been put in place after some, apparently, very intense debate.  There, we used the LocationFunctionOperatingSystemNumber kind of naming system.  So that the first Accounting server in Houston running Novell Netware would be HOUACTNW01.  Perfectly clear to me, actually, because of that job.  It’s a logical system and works well enough, though it does lack a certain “zing”.
At most other jobs, though, we tended toward the other way.  Once, I worked with a guy who named his servers after dead musicians and actors, but that was only so he could ping his favorite router and see “Hendrix is alive” come back to him.  Another place, we used various things and it was, well, far less themed and much more confusing.  I think it’s best to choose from a very, very large mythology or naming pool so that you don’t have to switch themes mid-stream.  We had some servers named for “gods of the underworld” and others that were named after space shuttles at the same company.  There was no rhyme or reason to it, really, just what the last guy felt like doing.

I’m not sure what naming convention I’ll finally use when I finally get around to redoing my network at home.  It’s hard to get motivated, you know?  When you do it at work all day?  Makes you feel sorry for sex workers and gynaecologists, not to mention urologists, doesn’t it?
(Yeah, this is what happens when I stay up way too late.  Or is it too early?)
