Diary of a Network Geek

Please, be careful.

We tend to treat USB thumb drives as essentially disposable these days, which, considering their low cost, they basically are.  At least, in one sense.  The problem is, those cheap, little drives still store an awful lot of data.  I recently read an article titled “You left WHAT on that USB drive?!” where the authors talk about several studies, formal and informal, where researchers scooped up random USB drives, either from eBay or the lost and found, to see what was on them.  The results are a little terrifying.  According to the article, “…about two-thirds of second-hand USB memory sticks bought in the US and the UK have recoverable and sometimes sensitive data. In one-fifth of the devices studied, the past owner could be identified.”  What’s more, in the case of one study, out of 200 drives, only 34 of them had been properly wiped out.  That’s just 17% of the drives.  Several had been formatted, but still had data that could be recovered off them.  Yes, that’s right, even reformatting the drives does NOT guarantee that they will be properly wiped out.

What’s more, the data that was left behind was of a very sensitive nature in many cases.  Everything from tax information to naked photos to photos of a soldier on deployment and at home, including the soldier’s address.  And, again, reformatting is not enough.  At least 8 drives out of the 200 examined had been reformatted, but had data on them that could still be recovered!  So, what can be done?
Personally, I tend to use USB drives until they absolutely don’t work at all any more, and I try not to put personal data on them in any case.
One solution is to get a USB drive that can be encrypted.  I’ve used several versions of the LaCie Imakey that includes an encrypted partition and utilities to manage it, but that doesn’t seem to be available any more.  A replacement might be the Kingston Digital Data Traveler Locker, which lets you set a password to restrict access, as well as doing hardware encryption of some kind and even backing up to the cloud in case the drive gets lost.  Granted those drives can get a little pricey, but how much does it cost to deal with the potential identity theft that lax personal security might bring?

If you have drives, USB or otherwise, that you’re looking to get rid of, then at least sanitize them before they go.  There are a lot of articles and utilities available to help you with that.  One that covers pretty much every drive you might have is How to securely erase external hard drives, SD cards, or flash drives, which details the steps as well as suggesting utilities to help you.  Now, for the most part, I assume that if you read this blog, as opposed to my other blog, Use Your Words, then you’re a geek like me and can handle more than consumer-grade procedures and software.  If that’s the case, or you’re feeling particularly brave, one great utility I’ve used is Darik’s Boot and Nuke aka DBAN.  It’s a free ISO you can download to make a bootable disk/drive that will let you securely wipe a drive before disposing of it.  It’s simple to use and free, but if you’re not comfortable burning an ISO to a disk or thumbdrive, then I’d recommend getting a more consumer-friendly product.

Either way, it’s a scary world out there to let your precious data roam free without a keeper, so be careful with those cheap, “throw away” drives.  If you’re not careful how you use them, they could get pretty expensive.

Advice from your Uncle Jim:
"Sanity is a one trick pony -- all you have is rational thought. But when you're good and loony, the sky's the limit!
   --from "The Tick"

As you might have guessed from the title of this blog, I’m a geek. In fact, I’m actually a professional geek. Rumor has it, being a geek is cool now. I’ll get back to you on that.
In any case, one of the ways my geek has expressed itself is in early support for Linux.  I’ve used Linux, one way or another, for more than twenty years.  It’s hard to believe, but it’s true.  What’s more, I’ve been Linux certified for more than ten years!  Strange but true!  I don’t use Linux as my main operating system, though, because I live in the real world, not a Techno-Libertarian Utopia.  And, yes, that means, I use Windows.  At home, it’s Windows 10, because that’s what came installed on the laptops I got for my wife and I while I was a highly-paid contractor in 2016 and we were refreshing all our electronics.  But, much to my surprise, there’s a way to run both Windows and Linux, together on the same machine!  Without having a dual-boot system!  Thanks to an article from the Linux Journal, which almost went the way of the dinosaurs last year, I have activated Windows Subsystem for Linux, which is ONLY available on Windows 10, and then installed Ubuntu, which is free, from the Microsoft Store.  The little screen-shot at the top of this post is Ubuntu, running in its own, little window, on my Windows 10 laptop.

This is exciting!
Now, I can brush up my bash scripting by setting up a series of rsync jobs to keep my two Western Digital MyCloud drives in sync, essentially backing one up to the other.  From the literature, I had thought that was built into the models I got, but it wasn’t.  I tried to use SSH to get that setup directly on the MyCloud devices, since they’re running some limited *nix kernel, but something about the way they were configured made connecting one directly to the other and running rsync from working “as expected”.  This, though, should get me around all that.
Now, all I have to do sort out the syntax for properly mounting the Windows shares I’ve set up in the Ubuntu virtual machine app.  So, I’m not 100% there yet, but this is a great start!

Not my usual Friday Fun, but great for system administrators trying to get ahead.

And, not too bad for power users trying to figure out some of what the professional system administrators are talking about when they’re trying to talk over your head.
What I’ve got for you this week, gentle readers, are “bite-sized” system administrator screencasts.  What that translates to are relatively short screencasts, usually 20 minutes or less, on professional computing topics ranging from using Ansible to implementing Docker to writing incident reports to project planning.  So, pretty much, a series of short, hyper-focused courses that you can sneak in during your lunch hour at your desk.  How awesome is that?

Okay, so only awesome if you’re a professional computer geek like me, but, still, if you are, it’s pretty awesome.  Also?  Free.  So, yeah, free professional development you can squeak in on your lunch hour.  All in all, not a bad deal.
But, hey, it’s Friday, so bookmark that and start your self-education program on Monday, okay?

Prepare yourself for some high-intensity geekery!

No, seriously.
So, I’ve been contracting somewhere that has virtually no network documentation and what little they did have got destroyed in a catastrophic event.  For privacy and security, not to mention client confidentiality, I won’t go into details on that.  But, as a result, one of the things I’ve been doing is rediscovering their network and documenting it as fully as possible.  For that, I’ve been searching out and using various templates.
Also, in a seemingly unrelated course of events, I’ve recently started using Evernote as part of my Getting Things Done revival.  I’ve been re-reading Getting Things Done, originally in preparation for starting a new job, and trying to get it going again in all areas of my life to better manage my time and efforts.  My wife raved about both GTD and Evernote, so I splurged and bought the $10 document from David Allen’s web store on setting up Evernote so that it was optimized for GTD.  It was some of the best money I’ve spent in a long, long time.  This combination is so completely awesome!

But, what’s even more awesome is the power of Evernote templates.  Their templates are really just a blank document that’s formatted in a particular way that serves as a starting point for a regular note style that you make over and over again.  They’ve written up a whole article on it; How-to: Save Time with Templates.  If you’re working with Evernote, it’s definitely worth the time and trouble.  My personal template library is hitting 59 items right now, but I’m sure there will be more.
And, that, finally, leads me to my Friday Freebie; EvernoteITDocumentationTemplates. These are a collection of six templates, so far, that I’ve munged together to let you more easily record the basic information an IT professional might need to capture about devices on their network.  I have no doubt there will eventually be more.  In any case, go ahead and download these and enjoy them.
To get those into your personal Evernote, check out their article How to Backup and Restore Notes and Notebooks.  It’s got step-by-step instructions there for getting started.
Good luck and enjoy!

So, I was laid off Tuesday.

I wasn’t surprised by it, for sure, since they’ve been laying off two and three people a week for the past six weeks or more.  I’d be lying if I said I wasn’t disappointed, though.
A couple weeks ago, another sort of IT person, who’s here from the real parent company in China, was sent over to my location to gather up all the passwords and access I had.  Probably to make a copy of my laptop, too, but I kept that with me or locked up.  I know they were trying to be sneaky or subtle when they did it by distracting me with a phantom project, but, really, when someone is sent for the passwords, there’s really only one thing to think.  Then, when I asked why the theoretical project I was supposed to be working on hadn’t been implemented when it was first sent out for bid 18 months ago, I was told that it was due to lack of funding.  If there weren’t funds then, when the company was doing well, where were the funds going to come from now that so many people were being laid off?  I got the answer to that question on Tuesday morning, so I went in and packed up my desk, just in case.  You see, ever since I worked for a company that got liquidated, I’ve kept my personal belongings at work limited to what I can easily put into one, small box, which I keep under my desk.  Just in case.
Apparently, the fact that I went into my final interview with a 99% packed desk shocked the people firing me.  But, then again, they were always underestimating me at that job anyway.

So, regardless of all that, when I got home Tuesday afternoon, I applied for unemployment with the Texas Workforce Commission.  I was able to go on-line and sign up, which is an improvement over the last time I was out of work, when you had to call or go in person.  Sadly, I won’t be able to apply for a payment until the 28th, but I’ve started my job search.  Well, really, I’ve just intensified my job search as I’ve been looking for about a month.  And, while I’ve had a couple phone interviews and at least two really good prospects, I still need to keep the requisite job search log.  The Texas Workforce Commission has a downloadable form on their website, but, honestly, I kind of hate it.  So, instead, I made my own spreadsheet.  I’ve shared the blank one at the bottom of this post.
Some of the columns have drop-down choice boxes in them and the form has gotten kind of big to accommodate all the new fields they have on the original form.  It is, however, formatted to print all on one page for easy verification should it be requested.  And, yes, for those of you wondering, I verified with the Texas Workforce Commission helpline that a spreadsheet is just fine for recording your job search activity.

So, grab a copy of the form and good luck in your job search!

It seems to be all the rage, but I think we’re going to do it anyway.

I killed “cable” television a number of years ago, after having lost it during Hurricane Ike in 2008.  I used Netflix, before streaming was really a thing people did, and binge-watched shows a disk at a time.  Lost made a lot more sense when I watched four episodes a night, and not one a week.  The plot continuity between episodes was a lot easier to follow and I really enjoyed it.  I found that I read more and wasted less time.  I was more productive and more relaxed than I had been in a long time.  And, I really didn’t miss having all those channels that I didn’t watch to surf endlessly, trying to find something “good to watch”.  In short, it was no loss to me, outside of the cost, to cut cable.
But, in early 2012, I met a girl and things changed.

Okay, so that’s a little poetic license.  She’s not “a girl”, but is, in fact, a woman my age.  However, like virtually all significant change that has occurred in my life, a woman, whatever her age, was at the heart of it.
Seriously, though, after four, solid years with nothing but books, the internet and Netflix for entertainment.  But, before my future wife moved in, I got the television service for AT&T’s U-Verse again.  I got the U-300 package to get her some specific channels that she wanted to watch.  Most important to her was Turner Classic Movies, because she is an old-film buff and part of several on-line old-movie communities.  To not have that would have been a “deal breaker” and, well, that wasn’t a deal I was willing to break.  So, in the spring of 2013, I got cable TV again and got two wireless DVRs as part of the package.  Wow, did she widen my horizons with the introduction to the DVR!  I don’t know how I managed to get by without one before.

In any case, all of that is to say, we’ve decided for various reasons, including costs, to cut cable again and go to streaming services.
And, I’ve decided to document the transition, outlining the choices we made and why we made them.  This post will anchor the series and give you a reference point for what we have now.  Specifically, we have AT&T U-Verse, with the 6 MBPS “Elite” internet package and the U-300 channel package with one wired DVR receiver and two wireless DVR receivers.  Additionally, we have Netflix streaming with HD and two-disks-at-a-time rental with the Bluray option.  Our current total is roughly $200/month or $2400/year.  I’m fairly confident that we can cut that in half with some judicious changes.  And, also because a handy savings calculator told me so.

Want to run the numbers for yourself?  Get your bills and click over to the “Should you cut the cord?” Calculator at Slate.com.  You may be surprised.
And, keep coming back here for details and updates on how we do what we do, saving money and gathering information as we go.
Just do be warned, this is primarily a blog by geeks for geeks, so at some point I’ll probably get into some technical stuff as I work to replace or improve some of the systems we’ve grown used to having.
The updates won’t come every week, but I’ll try to keep them regular.  And, they won’t normally come on Friday after this one, either.

Free training, of course, for my favorite content management system; WordPress.

Not familiar with WordPress?  Well, you should be since it runs or manages a significant percentage of the web.  As of this writing, “significant” means about 25% of all websites.  Yeah.  That’s a lot.  And, there are a lot of reasons for that.  For one thing, it’s well supported and lots of developers work with it, so getting help and customization work done is relatively easy.  For another, it’s easily…

First, let me say that I don’t endorse this as a way to avoid upgrading.

Second, let me fully affirm that this is completely awesome!  And, as someone who maintains a Windows XP virtual machine to run some older software for my camera, I am thrilled to have this option, for as long as it lasts.
The hack is pretty simple, basically just adding a small entry to the Registry.  First published by Wayne Williams at BetaNews a day ago, it’s been all over the internet today.  I did it earlier on an old machine at work and it worked great.  Your results may vary.  The steps are simple and in that linked article, but I’ve included the 32-bit version of the registry file that you can just download and import to your machine or virtual machine.

Use at your own risk!
And upgrade as soon as possible!
(Here’s the link to the REG file.)

Advice from your Uncle Jim:
"The person who WILL NOT read is no better off than the person who CAN NOT read."

A file-manager that was originally forced on me, but which I’ve come to rely upon for my daily work.

About ten years ago, I was hired by Oceaneering for a world-wide roll-out of an imaging and support project.  I won’t mention the name of the manager who hired me, because, well, we ended up having a problem.  As it turns out, he didn’t want to take on the project.  What’s more, he wasn’t big on hiring guys “like me”, who had certifications and so on, but he was forced to do just that by the same CIO who thrust the desktop imaging project on that manager.  The CIO, from what I understand from third-party sources, has since “retired”.  I don’t know if the ill-fated project ever was completed because both of the people originally assigned to it, including me, were encouraged to “find other opportunities to excel”.  Internal politics aside, I mostly blame my divorce for costing me that job.  It turned out okay, though, since I landed at Seatrax shortly thereafter and have been quite successful there.

The other good thing to come out of that mess was that manager forcing us all to use a program called, at the time, “Servant Salamander”.  As you can see from the thumbnail included on this post, it’s a file manager.  But, it’s more than just that.
There’s a lot of history with this utility.  Some of my readers may be familiar with the old Norton Commander, which inspired Petr Šolín to make the earliest version of Servant Salamander as freeware.  Or, they may be more familiar with the text-menu-based utility for Linux called “Midnight Commander” which is sometimes just referred to as “MC”, since the name of the actual command is “mc”.  This tool looks almost identical to Altap Salamander and if you’re used to Linux systems, running Salamander may make the transition a little easier.

Of course, the basics are there.  The side-by-side default view of two directories lets you easily copy or move files from one directory to the other via a quick series of clicks to select files and either hitting the F5 or F6 key respectively.  You can also use the context-sensitive menu to rename and delete files or directories, create directories, edit files or use the built-in viewer to preview files, all with the touch of a function key.  You can also connect a network drive, if you happen to have a local fileserver of some kind with available shared directories.
In fact, while there are menus, virtually every command can be accomplished via a series of keystrokes or a combination of keys.  For instance, while I usually use the mouse to navigate directories, a simple shift+F7 will bring up a dialog where I can type my desired destination directory.  Or, I can do  a search with a quick Alt+F7.  (And, the search function built into Salamander is quite good, if you need to find something.  At least as good as the built-in Windows search!)

But, what really makes this utility shine are all the extras.
For instance, sometimes, I have to deal with a lot of files in big directories that need to be synchronized between servers.  Salamander has a built-in function to compare directories.  It will even compare subdirectories, if it comes to that.  As someone who manages multiple websites, the FTP plugin for Salamander, which allows me to quickly connect to a remote server and then navigate it like any other directory, has been such a time saver and is so convenient for me, it may be the main reason I have continued to use Salamander!  I can even maintain a list of regular FTP sites so I can simply select them almost like I would change to any other drive on my system.  And, yes, once connected, I can transfer files back and forth with the same commands as I do on local drives.  (Though, I have to admit, every time I install Salamander on a new computer, I forget to set the default options for the FTP plugin to “Use passive transfer mode”, which seems to be the standard for all the FTP servers I connect to on a regular basis.)
Another plugin lets me view ISO CD or DVD disk images, which can be very helpful when you’re a system administrator and trying to retrieve a single file from an ISO downloaded from a vendor.  And still others do everything from opening compressed archives to comparing files to copying entire disks.  Further, if you managed both Windows and Linux servers, as I have, the WinSCP plugin makes it much easier to transfer files to a Linux host securely, though, at the moment, there’s not a 64-bit plugin, just a 32-bit version.  Again, all very handy things to be able to do, especially for an IT professional!

While there is a free, trial version of Altap Salamander, after having used the licensed version, I really prefer that and recommend that you spend the money on it.  As of this writing, if you get the latest version, along with all the plugins, only some of which cost extra, it will run €44.80, or about $63, for a single license.  And, that will give you access to a year’s worth of updates.  That may seem like a lot, but, trust me, the extras are all worth it and Petr updates it quite frequently.
Personally, I don’t know how I would make it through my day without using Altap Salamander!

So, my “Tools for Tuesday” posts are getting a bit more challenging for me time-wise and quality-wise.

That’s why I missed last week, actually.  I was just too busy to get a good review post done and shared in time.  And, I think maybe it’s time I start scaling that feature back, just a bit, to one post every other week.  I hope it will let me maintain both the quality and quantity of “Tools for Tuesday” posts.

And, now that bit of house-keeping is out of the way, on with the big show!
Or, at least the main post.  This week, I’m sharing something that is probably familiar to many, if not most, of my readers; WordPress.  WordPress is the blogging software that I use to run this blog, not to mention my other old blog at Fantasist.net, as well as the entire site at JKHoffman.com and my wife’s site at OrganizingDecorator.com.  It will also be what I use to run two other projects that I’m working on developing, Find My Photographer and Find My Decorator.
As you fellow devotees know, this past week saw the release of WordPress 3.9, but I’ve been using this free, open source software since version 1.2!  Before that, I used MovableType like many early bloggers, but with their “great license debacle”, many of us jumped ship and found our way to WordPress.  I know one reason I, personally, chose to go that route was because the lead developer of the project is Matt Mullenweg, who happens to hail from Houston, where I live currently.  I liked the idea that I might run into him at one of the local computer groups that were around at the time.  I never did, but I did go to DEF*CON with someone he used to play in a band with back in 2012.

In any case, I’ve used WordPress for a long time, especially in “internet years”.
Back in the day, it was really only a blogging platform, but it was super easy to setup and maintain.  And, perhaps more importantly to me, especially back then, it was easy to extend.  I haven’t written any plugins lately, but WordPress is so easy to use and code for that even I could write add-ons for it.  I’ve even done some pretty significant modification of themes, and anyone who knows me knows that I’m about as far from a designer as you can get.
Since those early days, though, WordPress has really grown up!  Now, not only can it handle simple blogging, but it can run your whole site.  There are detractors, of course, who say that it’s not really a full-featured content management system, but they’re wrong.  WordPress has built-in features that make running an entire site easy, like the ability to set a static home page and super-simple page management.  Add to that a completely customizable appearance through themeing, limited only by the designer’s vision and ability and you can see why WordPress runs about 19% of the internet and has been downloaded at least 46 million times.  But, what’s even better is that there are so many people doing add-on development in one for or another that there is a theme, widget or plug-in that will pretty much do anything else you could want that’s not already rolled in.  And that’s really saying something because WordPress “ships” with a pretty robust gallery and media management system already rolled into it.  Other important features include good, reasonably secure user management, a commenting system and an easy to use interface.  Granted, the interface is always being worked on and improved, so it’s always changing, but it’s never been a distraction for me.

Other features include autosave, spell check, automatic upgrading, built-in plugin installation, sticky posts, comment threading/paging/replies, bulk management of posts and comments, image editing, a Trash/Undo feature, bulk plugin and theme updating, a multi-site option allowing multiple custom blogs to be run from the same installation, it comes in at least 70 languages and it’s even pretty optimized for search engines!  But, it think what matters most to me is that WordPress has a huge community around it, supporting it going forward, developing for it and making it better, even though it’s free.  I can download the latest version of this beauty any time I want, install it on the webserver of my choosing, and make my voice heard on the internet.  I can build with it or I can build on it to make it do whatever I need or want and anything I create with it is all mine.  No one owns a piece of it and, as long as I write my own posts and pages, I keep and maintain all rights to all the data that I shove into it.  That’s pretty incredible when you think about it.

And, yes, it really is easy to install and use, so if you’re thinking about starting a website, I highly recommend using WordPress to do it.  Don’t listen to the nay-sayers that claim WordPress isn’t up to the task either, because a lot of really incredible websites use WordPress.  You can check some out at the WordPress Showcase.  You might be surprised at some of the high-profile sites that you have already been to that use WordPress!  All that power can be yours, too, if you just take the time to download, install and use WordPress!
