Diary of a Network Geek

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!

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!

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!)

So, last month, I was talking about rolling your own distro.  This week, it’s rolling your own LiveCD.

Over at TechRepublic, they ran an article on using some tools built into Ubuntu to make your own, custom Ubuntu LiveCD.  For those of you not in the know, a “LiveCD” is a bootable version of an operating system, in this case Linux, that will run from the CD without installing on the workstation.  It’s a great way to try out a new operating system or bring a portable, emergency software toolkit with you without damaging or changing a PC.

The tool, for my fellow wireheads, is called Reconstructor and the article pretty well takes you through step-by-step on how to do it.  Well worth the read if you’re a Linux geek, most especially if your distro is Ubuntu.

Or are you just happy to be using opensource software?

I never know if I should capitalize “opensource”. Should it be OpenSource? Gah, I hate stuff like that!
But, I love Linux. I may not be incredibly well versed in the ways of Ubuntu, but, that’s okay because now I can download a free pocket guide to Ubuntu in PDF format. Of course, you could buy the $10 print version, but why?

So, c’mon you Linux geeks and wannabe Linux geeks! Go get it!
