Diary of a Network Geek

I always come up with these ideas just before someone else announces their version to the media.

No, seriously, I was just thinking about finding the time to research what kind of power requirements a small network would have and figuring out what sort of solar setup would meet those needs.  I was thinking about it for disaster recovery, like after a hurricane or an earthquake, but, still the principal is the same as the Computer Aid Cyber Cafe in a Shipping Container.

I may still write up my ideas, one day, but, I think not during this particular hurricane season.

Normally, I have trouble getting a good signal in my house!

But, I can imagine wanting to create a “cell-phone free zone” in my house to free me from that itch to answer incoming calls.  Imagine a writer trying to get some peace and quiet, for instance.  Or, even someone who entertains a lot of high-tech people making a “safe haven”, of sorts, where friends don’t have to worry about being interrupted by cell phones.

Well, now, with the Painting Cell Phone Jammer, which I found via Gizmodo, you can make that no-cell zone in your house.  It comes complete with a remote, so you can turn it on and off.  All you need to do is plug it into the wall.  Oh, you may want to actually change the art, too, because the stuff it comes with is sort of, well, sucky.  But, I could live with that, I think, to get some peace from those after-hour support calls on my cell!

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.

I probably should have posted this last week, when it was fresh, but…

So, I have this issue at work.  We run an older version of Autodesk Inventor.  Actually, Inventor 10, which we really only use for AutoCAD 2006.  But, this presents a problem.  You see, this version of Inventor won’t install on Windows 7.  Might work on Vista, but who in their right mind would run Vista?  Right, so, I’ve got a problem.  If I want to upgrade someone’s Windows version, or even their whole machine, I can’t.  So, what to do?

Well, as it turns out, if you get the super, ultimate, Professional version of Windows 7, it comes with a Windows XP “compatibility mode”, which is really just a virtual machine.  If you crank up that virtual machine, it will install that old version of the program my engineers and draftsman absolutely must use.  What’s cool, though, is that once you install it, it makes short-cuts on the Start menu that let you launch the old program encapsulated in that virtual machine.  How cool is that?!  So, problem solved, right?

Well, almost.  Turns out the one guy I installed it for, as a test, is having some issues with adding text to a drawing.  I haven’t quite figured that bit out yet, but, still, I’m working on it.  And, all things considered, it’s a small glitch in an otherwise very clean solution.

Uh, yeah, so you may now return to your regular Memorial Day Weekend time-wasting on the Internet.
That is all.

Right, so you know I love Linux, right?

But, beyond that, I love all the bootable tools and utilities and things that Linux let’s you do to Windows machines.  Well, there was a time I carried several “flavors” of Linux on various USB keys in my pocket, depending on what I wanted to do.  In that spirit, I have another tool to create Linux USB Keys for you; LinuxLive USB Creator

It’s a free, Open Source utility for Windows that let’s you create live USB keys running Linux.  The link will take you to the download page on SourceForge.

If you’re a geek like me, it’s worth a look!

But, not the way you think.

Have you ever had an image that you downloaded from somewhere, but then forget where, but you’d like to find more like it?  Or, how about this scenario, say you downloaded a picture, but you’re sure the site where you found it isn’t the creator, and you want to find the creator.  Or, even better, say you’re a photographer and are looking for who’s taken your photos.  How do you go about finding those things?

Well, one way might be TinEye Reverse Image Search Engine.  You feed it the image and it searches for that image out on the Internet.
How cool is that!?

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.

This is only of interest to people who have webservers, but it’s worth writing about.

According to TechRepublic, QualsysGuard Malware Detection is letting you scan your webservers for free.
You have to be able to verify the domain with an e-mail address, so it really is for serious folks who actually have a webserver and verifiable e-mail, but it is free.  No word on how long it will be free, but, for the moment, it is, so go get it!

Long time readers will know how I feel about the H1-B visa issue.

Look, in the IT business, the H1-B visa program is well known for the rampant abuse and the undercutting of salaries for American workers.
For you who are new to the blog, here’s the basic run-down.  I think American workers should get jobs, of all kinds, not just tech jobs, before we import workers.  But, we should import skilled workers who will pay taxes before we send those jobs off-shore.  The reason I don’t like the H1-B visa program in particular is because I know for a fact that it was used to unfairly, and apparently illegally, undercut American workers and put them out on the street in favor of grossly underpaid imports.

Well, in a small bit of good news there, eWeek is reporting that the Federal government is going after $1.4 million in wages that H1-B visa holders were cheated out of via Peri Software Solutions.  For those of us in the industry, I don’t think it’s any surprise that these folks had offices in India and had cheated 163 Indian IT people out of more than $1.4 million dollars in fair pay.  Pay, incidentally, that they would have paid taxes on to the U.S.

While I think this is a great step, I can’t help but wonder, how many more companies like this are there who haven’t been caught or prosecuted?  How many people have been unfairly abused this way?  How many jobs were lost?  How long will it take to do something and fix this broken system?

It’s not quite the “birthday” of the mouse, but…

Today is the 41st anniversary of the first time a mouse made its commercial debut, though the patent was actually granted just a few weeks earlier on November 17th. That’s right, the mouse, that marvel of modern technology that most of us use daily is just a little older than I am. Invented by Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, CA, the original mouse was little more than a square, wooden box, but the little device would change the world. Engelbart showed how the mouse could let a user jump from text on one part of the screen randomly to another section without having to scroll through the text inbetween. Doesn’t sound too revolutionary to us today, does it? But, think about how you navigated to this page to read this little blurb, then try to imagine doing it without a mouse.  Or, imagine trying to use Photoshop or any other graphic design program for that matter without the point-click-and-drag of a computer mouse.  Yeah, pretty much everything cool you can do on a computer these days involves a mouse or similar pointer.  Now, of course, to me, that’s the real genius of an invention like the mouse; it seems so obvious that we wonder why we didn’t think of it sooner!

So, happy demo day, little guy. Thanks for giving me a job and us a way to waste time at work.
