Diary of a Network Geek

No, those quotation marks aren’t ironic.

Last year, in August, I wrote about a free service called LensTag that would help you track your camera gear if any of it went missing.  Well, they’re back in the news for another service!  This one was discovered by accident by their president’s wife who mistakenly turned on the tracking for her camera when a couple of flashes got stolen.  It turns out, she started getting notifications about where her photos taken with that…

This week I’ve got two very serious freebies for you.

Security, as some of you may know, is near and dear to my heart.
In my day job, I’m a system administrator and constantly worried about security.  It’s a huge issue.  Lately, you all may have been hearing news stories about the “Heartbleed SSL vulnerability” which, in theory, could endanger your personal login information, as well as other account credentials or other things you’d want to keep private.  It’s not entirely clear…

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!

I feel like I’ve cheated my readers lately, so I’m offering two links that are kind of related.

Well, they’re related in the sense that both links are about making beautiful things.
And, I’m sharing two links this week because, well, I realize how distracted I’ve been by so many things outside my control and the way I deal with that is by trying to be of service to others.  It brings me back to center and helps me get a better…

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!

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.

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.)

Looks like the free LogMeIn option is going away.

It had to happen eventually, but it kind of sucks for those of us who relied on it to get certain things done.
They sent an email this morning, giving free users, like me, about a week to either pony up for a pro account or find another solution.  I figured I would have to search around for a while to find an alternative, but, thankfully, the folks over at Slashdot were already talking about it in the thread Short Notice: LogMeIn To Discontinue Free Access.  The ever helpful commenters had a lot of suggestions, with varying levels of snark and technical skill required and, you know, actual usefulness.  There were some interesting and baroque solutions to this pretty common problem.
Now, I’m a devote of Perl, so the idea that “there’s more than one way to do it” is near and dear to my heart, but some of those solutions on Slashdot were more hassle than they were worth!

The solution I looked at and quickly tested today was the Chrome Remote Desktop plugin.
I chose this for a couple of reasons.  First, it was free.  Frankly, that was probably the most important requirement.  I don’t have a budget for a lot of things I don’t use everywhere or every day, so I need to be careful how I spend that money.  Secondly, it was easy to implement and use.  There were several options discussed on Slashdot, but most of them were going to take creating one or more accounts on services like DynDNS or something similar, or they would need a new server or other dedicated machine.  That wasn’t going to work for me either.  I need something simple to install and use.  Mostly because I’m lazy, but still, the requirement is there.  And, thirdly, there had to be some kind of security on it so random users couldn’t log into machines.
Now, the “down-side”, such as it is.  This solution requires that Chrome be installed on any machine you want to get access to or from.  This is a Chrome plugin, so, obviously, it won’t work without Chrome.  Secondly, to get it and install it, you need a Google account of some kind, even though it’s free.  Gmail will do, and in fact was what I used to get the plugin from the Google App Store.  And, yeah, that was pretty much the only “bad” thing about it.  Again, for me, it wasn’t a big deal because I tend to install Chrome on any machine I happen to work on for any length of time, but it could be a hassle for people who don’t use or know Chrome.

Setup was easy and prompted me to enable remote connections to my machine then immediately asked me to set a PIN to restrict access.  I like that it did that.  Also, the PIN is required to be at least six digits, which is decent enough security.  I, personally, made it seven digits, but for the truly paranoid, you can make it longer.  I first set the plugin up on my work machine and then set it up at lunch on my home PC.  Again, I was asked for a PIN.  I happened to make it the same, but I’m pretty sure that PIN was unique to each machine, so, again, for the truly paranoid, you can lock this down pretty well.  After that five minute install, I was able to take over my machine at work.  Boom!  Just that easy.

As a further test of the plugin’s ability, I checked the box that allowed for “off-line access”, then I shut down my Chrome browser at home.  Once I got back to work, I tried remotely accessing my home PC.  I was asked for the PIN and then I was right in!  Again, just that easy.
Also, I should note that my work PC has only one monitor, but my home PC has two and Chrome Remote Desktop plugin flawlessly displayed both monitors.  It was absolutely amazing!  And, the connection was fast!  Frankly, it was faster than LogMeIn was most of the time.  It was great!

So, I know that LogMeIn won’t miss my business, since I never really gave them any, but I cannot say that I’ll miss them.  This is a great solution to the problem of remote access and I cannot be happier with it.  We’ll see how things go over time, of course, but this looks like a great, easy and free replacement for LogMeIn.
If you all find other solutions or solutions that you think work better, leave the information in the comments!

So, at this point, you should be just about done with your novel for NaNoWriMo.

If you’ve kept pace, in the next 24 to 48 hours, you should be wrapping up your 50,000+ pages and breathing a giant sigh of relief.
You’ll want to step away from the writing tools of your choice and take a break before editing your fledgling star into something that people will want to not only read, but tell their friends about having read.  But, first, you’re…
