Diary of a Network Geek

Okay, this isn’t exactly a new idea, but it’s still worth sharing.

I got this from Lifehacker back in 2012, but I’ve been behind in my link sharing, so I’m just getting to it now.
The idea is simple.  Reading on-line is rarely the best, most comfortable, most convenient way to keep up with all the things we want to read, especially all the “long form” articles that really get in-depth on topics we care about.  That’s where Readlists comes into play.

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!

That’s pronounced like the peanut butter brand, by the way.

At least, that’s how the original creators pronounced it, back when Compuserve was a thing.  They created the GIF as a compressed graphic format to minimize data usage back in the “Days of Dial-up” for Compuserve when modems ruled the Earth.  But, I bet they never thought that their “little” contribution to computer culture would go so far.  For instance, when the GIF came out, it didn’t have animation as a…

A screensaver that monitors your server.

This may not seem like much of a “tool”, since it’s pretty passive, but when you have a server that’s getting old and failing, being able to quickly glance at what its performance is like can be a real benefit.  And, for the past eight months, I’ve been running a server that, to be honest, was a little too old to be in production.  People would complain about it pretty much constantly, even, I suspect, when it may not have been the actual problem they were suffering from.  I’ve since replaced the server, but I kept running Systemometer on both the old server, which now serves as strictly a backup server, and the new, shiny, Windows 2012 server, just so everyone can see the difference.

But, let me be really specific about this; Systemometer is a configurable monitoring tool that shows system performance and resources in a spider chart. Seeing the varying shapes of displayed polygon, representing a visual pattern drawn based on normal, or critical, system states. Once you get used to it, this snapshot view helps to read the overall system status at a glance. Just looking at the screenshot in this post, which will enlarge if you click on it, you can see that a lot of information is displayed.  Notice, for instance, that there are 12 “CPU”s listed.  Since this is a modern, multi-core server, those are really just all the cores being displayed, with the current processor time in yellow and the average processor time in green.  If I wanted to, I can also set Systemometer to display the maximal processor usage, but as this is a new server, I haven’t bothered to set that.  The same goes for the number of processes the server is handling, as well as the number of threads.  Also displayed is the physical and virtual memory usage, total drive space used and the hard drive seek time.  Notice how almost everything falls well within that red circle on the display?  That’s because the server is new and being used well below it’s capacity, by design.  This is the second server upgrade I’ve done since I’ve been at this company, and I’d like to not have to do one again soon.  That’s also why the number of threads is reading like it’s in the red, even though it’s not.  The new server is so new that not all metrics have been calibrated to display correctly.
Also, notice that the two performance polygons are yellow and green.  The yellow is the current usage while the green is the average usage.  It may be hard to tell the difference between the two because I took this screen shot on a Sunday afternoon with minimal usage.  Of course, the server being primarily a file server and an Active Directory server, the average usage is pretty constant in any case.

It may not be obvious from the screen shot, but I’m running this as a screen saver, which is only one option for using Systemometer.  It can also be used as a kind of replacement performance monitor instead of using the built-in Task Manager for that function.  Actually, one way I validated the results I was seeing from Systemometer was to run it next to Task Manager and compare the displayed performance information.
Personally, I like running it as a screen saver because I can quickly check on my server as I walk past the screen into or out of my office.  Also, it seems to impress people who see it and can’t make heads or tails of what they’re seeing.  It’s not big, fancy monitoring system, but unless you really know what you’re looking at, the average person isn’t going to figure that out!

Finally, the other reason I use Systemometer is that it’s free!
Yep, that’s right, absolutely free.  Of course, it may not ever get updated again, but I’m okay with that, as long as it still works as it has been so far.

Real programmers code in text editors.

And, for what it’s worth, so do I!    
Look, I’m the first to tell you that I’m not a programmer.  Honestly, I think it would kill me to sit in front of a monitor all the time and do nothing but bang out code, then re-read that code for errors and spend endless hours debugging it.  Still, I have done a bit of Perl programming.  And, I am, as of this writing, a Level 11 PerlMonk, which is something that makes me proud.  I’ve also done some pretty heavy customization of my blogs and, on the rare occasion that I muck around in the HTML and CSS, I do it in a text editor.  Actually, to be specific, I do it in UltraEdit.

I’ve used a couple of versions of UltraEdit, but the screen-shot a the right is from version 20.00.0.1056 which is the most current version at the time of this post.  As you can see, it’s easy to have multiple files open and to transfer back and forth between them by simply clicking on the tabs with their names at the top.  Also, the built-in file explorer makes it easy to find and open your target file.  Again, referencing the screen-shot, you can see that UltraEdit has built-in code highlighting, which can be turned off if it becomes distracting.  Frankly, that was one of the features I first came to love about this program, along with the spell check.  But, what really sold me was the “search and replace” function, which lets me easily replace line breaks with tabs or other characters.  That may not seem like a big deal, but when you’re dealing with a lot of raw text which needs to be manipulated in particular ways for input to other programs, or to fix output from some programs, that feature becomes invaluable.  Along with that is “Column Mode”, which will let you treat large sections of text more like columns in a spreadsheet than just raw text.  Believe me, that alone has saved me an enormous amount of time when I have to reformat text taken from a web page that has no export function!  Add to that the super simple sorting functions that include the ability to remove duplicates in a huge list and the really flexible macro system and you have a system administrators new best friend!

Of course, as I mentioned already, I also use UltraEdit to work with all the code I have to manipulate.
My “day job” doesn’t require that I code anything, thankfully, but for my own interests, I often find that I’m creating or editing a lot of different kinds of code.  I play with everything from Perl to PHP to HTML to CSS (which is what’s in that screen-shot above).  The fact that UltraEdit automatically adjusts the code highlighting as I switch between the different files by default has been super convenient and, at times, really helpful.  Most of the time, I’m updating or fixing someone else’s code for my own purposes and trying to remember where the closing tag in an HTML or PHP document that I didn’t create is can be daunting.  Code highlighting has really helped that.
That’s also where the built-in macro functions have been a big help.  I can record one, small action and repeat it as many times as I need to throughout a file with just a few keystrokes.  That can come in really handy when duplicating lists of variables, for instance, or converting a list of text elements into an array.  I can just insert the code which defines the element as part of the array in front of each bit of text in a matter of seconds.  Again, a huge time-saver.

Currently, this very useful utility is $80 for a new license or $40 for an upgrade, which is what I got.  I think an old employer actually paid for the original copy that I upgraded.  Either way, though, the price was worth it to me!  If Perl is the duct tape of the internet, then this is my utility knife!

UPDATE: Somehow I missed telling you all about one of the coolest features of UltraEdit – additional syntax highlighting files.  IDM has an incredible list of additional code/syntax highlighting files that you can download for free here.  My favorite?  The Cisco IOS code page that makes the huge ASA5500 configuration files I’ve been looking at for my latest gig easier to read (i.e. “actually comprehensible”)!  The instructions for adding them are on that page, too.

Guess who’s spending the weekend upgrading the company’s main server?

Finally after dealing with an aging server for too long, we’re upgrading.  And, not a minute too soon, either.  I have the joy of migrating Active Directory from a Windows 2003 server to a Windows 2012 server.  Not to mention, I get to migrate printing services, an iSCSI array connection, DNS and DHCP.  Wee!  What fun!

Well, I suppose that’s why I get the “big bucks”, right?  A system administrator’s work is never done!

I love this device!

Almost a year ago, I took a photography class from Syl Arena and he mentioned, in an off-hand comment, that he used a PogoPlug to access his files from home while on the road.  Now, I’d heard a little about the PogoPlug before that, but not much and with all the cloud storage services, like Dropbox, around, I didn’t really pay too much attention to it.  After hearing Syl go on at length about how easy it was to use, I read a little bit more about it.  I was suitably impressed, but just didn’t have the time or cash to really go ahead and follow through on a purchase.  Then, thanks to Gizmodo, I saw that Adorama had the entry-level PogoPlug on sale for $17.99, including free shipping.  The price has since gone up a dollar or two, but it’s still cheaper than full price and, let me tell you, completely worth it!

In brief, the PogoPlug is a network device that allows you to hook up USB-based drives to share on a network and the internet.  The device has six connections; one for power, one for the network cable, and four USB connections for storage.  I got mine hooked up in about five minutes.  Really, all you need to do is connect it to your network, attach storage to it and sign into your free my.pogoplug.com account to configure the device.  There’s an option once you sign in to check for new PogoPlug devices and, once yours is found, to configure the sharing services, if you want, or to upload files.  And, that’s pretty much all there is to the setup.  It really took me all of five minutes, and that was because I had forgotten to turn on the external USB hard drive enclosure I had attached to the PogoPlug.  Then, I just started uploading files.  And, the next day, to verify that I had done everything correctly, I signed in to the iPhone app while I was at the office and checked to make sure I could see my data remotely.  And, I could!  It really was just that easy!

I was even more excited when I discovered the slightly hidden ability to upload files directly to the PogoPlug without having to go through their webpage!  All I had to do was download and install the companion software which they offer for free.  They have both Android and iPhone clients as well as clients for Windows, Mac and Linux.  That downloadable software also let’s you do regular backups from any device you load it on to your PogoPlug, even over the internet!  Once installed, it makes your entire PogoPlug available to you as if it were a mapped drive with a drive letter and everything, just like any other network attached storage, except, of course, it will let you attach to that PogoPlug over the internet.  I’ve tried other things that claim they’ll let you have your own “personal cloud”, but they’ve all had problems when they bump up against the security I run on my network at home.  The PogoPlug, however, was even easier than advertised.  It was amazing!

There’s only one, small problem I’ve encountered with the PogoPlug and, really, it was only with the Android app.  I run a rooted Nook which I often use to read PDF files.  When I open PDF files through the Dropbox Android app, they launch right into Adobe’s PDF Reader without any issue.  But, when I try to do the same from the PogoPlug app on that rooted Nook, it gives me a message about downloading the file, but it never opens.  I hope that bug will be corrected in future versions of the app, but it’s a relatively minor issue, all things considered.

I really cannot say enough about how fantastic this device really is.  I haven’t tried just plugging in a regular USB thumb drive yet, or the outer limits on size, though I do have another USB drive enclosure and a 2 Terabyte drive that I’m itching to get hooked up.  Not to mention how deeply I want to dig into the software capabilities.  Also, I’m hoping I can get another cheap 2 Terabyte drive and figure out how to clone from one to the other to create a backup.
But, again, even if I can’t and I’ve seen all the possibilities of this device, it’s still awesome!
(And, yes, that link to Adorama which has sales information about the PogoPlug is an affiliate link, so I’ll make a little money of it if you buy it that way.)

So, in support of NaNoWriMo, this month, I’ve decided to serve up nothing but writing-related links.

At a week into the process of writing your novel, you should be well on your way.  But, maybe there are some back-story details you’d like to fill in.  Maybe a character who needs an odd name, or who’s pockets you need to fill with random stuff.  Maybe you need a fictional timeline for a fictional nation.  Or, maybe you need a wacky science-fiction invention…

I like being free and independent.

I like the idea behind Instagram, but not the proprietary nature of it.
I don’t like giving up my rights to work I create.   Even when it’s just a little photo of a little moment captured with my iPhone.  I dislike, as Nicholas Carr called it on his blog, “digital sharecropping”. And, of course, now the ads have finally started on Instagram, solidifying my discomfort with it.  Why should I let them profit from even the smallest amount of my work without compensation?

Well, now, there’s a new program called Pressgram, that’s a free iPhone app, which allows an Instagram-like experience, but uploads the photos to my WordPress blog. You can upload them to your WordPress.com blog, or, as I do, to my self-hosted WordPress blog.  Word has it that there is an Android version in the works, too.  It’s a new app, so there are some on-going refinements, but it really is a great start, I think.

Obviously, I’ve been using it here and at my other site, JKHoffman.com, so I believe in it.  Yes, it took me a little fiddling to get the setting just the way I want and to sort out a couple other things, but, now that I have, I think this is going to work just fine.  I can already see the difference in my site stats!
Anyway, worth checking out if you’re leary of another ad-supported system that lets you share, but not much else.

Yeesh!  Can you believe I was so busy this year, I almost didn’t notice?!

No, seriously, I was so busy running around at the office and trying to get my lovely fiance’s website squared away that I totally missed that today was Sysadmin Day!
So, here are a couple of things for you to read, especially if you’re NOT a system administrator.  First there’s a link to Ten Things NOT to Say to a Sysadmin.  Trust me, I’ve heard all of these things, many of them just in this week alone, and they all make me grind my teeth!

And, then an XKCD that captures just what it feels like to be an overworked, under-appreciated system administrator:

XKCD always knows what I’m thinking! http://xkcd.com/705/

So, if you haven’t yet, do something nice for your system admin. They really will appreciate it!
