Diary of a Network Geek

Really, it’s about dust and keeping it out of your camera, but, let’s be honest, that really is the biggest issue in keeping your camera clean.

As part of their “photography 101” series, The Photo Argus recently ran a story titled “Caring for the DSLR Body and Lenses”, but it primarily focused on cleaning the body of the DSLR, including the sensor, and keeping dust out of the body going forward.  And, to be fair, dust in the body, especially on…

Are there really any websites that aren’t essentially blogs?

Okay, I know there are, but, considering that some people estimate about 1 out of every 5 sites runs WordPress, it amounts to the same thing.
In any case, these two tools I’m about to share can actually be useful to any website design.

First, there’s the graphic “place-holder” generator, lorempixel.
Using their tool, you can find and download “place holder” images that are generic, in either color or b&w, and the size you need…

I am not a designer.

This may be painfully evident from the look and feel of this website, which, I did not code myself.  It is a WordPress-based website which, at best, I have “themed” myself, but with lots of help from code “borrowed” via Google and other sources.  In fact, there are so many code sources it would be hard to link to them all or list them all or thank them all.  It’s the way of the web, I’m…

Naming kids is easy, but naming systems is hard!

And, no, I don’t mean giving your phone a pet name.

I have gone on at length in the past about the importance of naming systems.  It’s a big, big deal, especially if you ever have to go back and change any of those names!  Granted, it’s not as bad now as it was in the old days when you had to manually update dozens, or sometimes hundreds, of host files or configuration files, but, still, it’s a pretty big deal.  So, naming systems are often a topic of discussion, especially among hardcore network geeks.  I’ve been in more than one meeting about choosing a naming scheme that devolved into name calling.
So, there are many schools of thought on this.  One group of people think that the name should be meaningful, giving location and function information.  That’s a good idea, but it often results in names like HOUNOVFILESERV001.  (And, yes, that’s actually a name I used on a server once, for a company that no longer exists.  It stands for HOUston NOVell FILESERVer number 001.)  Sure, it tells you what you need to know, but they quickly become unwieldy to type and maintain.
Another group would say to name your servers, or routers, or what have you, after any group of things that will be easy to remember, like the names of the Seven Dwarves, or characters from the Dilbert cartoon, or, even, at one place I worked, the names of the old Space Shuttle fleet.  And, while I’m not a huge fan of that for many things at a business, it can be fun to ping a Cisco router named Elvis just to get the response “Elvis is alive”.  Certainly at home, I tend to favor a more fun approach using something light-hearted, like the names of cartoon characters or mythological beings or something similar.  But, my problem is always, which set of “things” to choose?

Well, the Naming Schemes Wiki solves that particular problem.  Yes, someone has started a wiki that gathers all the different naming schemes you all can think of in one place for your viewing pleasure.  And, in spite of any protests from your significant other, you can select, at your leisure, a naming scheme to use on your network that makes you smile.  (And, stop looking at me that way!  I know I’m not the only person in the world with a home network big enough or complicated enough to warrant having to choose a naming system for it!)  The maintainer also encourages you to add your own scheme, if, somehow, it’s been missed on this site.  Or, to add to any of the existing pages if you have something to contribute.

So there you have it!  All the endless naming possibilities for your home networking project this weekend!
Y’all have fun!

I am NOT a designer or web programmer.

Sure, I’ve dabbled with Perl enough to be a Level 11 Perl Monk on Perlmonks.org, but I’m not really a programmer.  And I’m sure not a designer, either, even though I can appreciate really good design work.  In fact, my ex-wife used to say that I was from the “big orange button” school of design, because I was more interested in the technology behind the button you pushed on a website than making…

A healthy mind is a creative mind!

And, let’s face it, a healthy mind is supported by a healthy body.  Exercise is one aspect of that, but at a more fundamental level, properly fueling our bodies and minds is, I think, the most important first step.  Last week, I linked to a site to help you put your diet on autopilot.  This week, I’m suggesting that you maximize your vitamin intake.  Not through taking supplements, though that’s not a bad idea…

What do YOU consider “essential gear” on a photo shoot?

I’ll be honest, most of the time, I’m shooting it’s usually a pretty “run and gun” affair while out interacting with the public.  People generally refer to that as “street shooting”, but I think of it as “impromtu portraiture”.  Either way, I’m generally working alone in situations like that, so the idea of working with assistants is pretty alien to me.  Still, I have to admit I’d really love to assist…

Have you ever wanted a “do over”?

Remember when we were kids and we’d be out playing and something crazy would happen that totally messed up someone’s game?  We’d more often than not give them a “do over”.  We’d let them reset and try again.  Wouldn’t that be nice to have in every aspect of life?
Well, speaking as a professional network geek, sometimes there is, at least on some network equipment.  We call it a “factory refresh” or, as the title of this post implies, a “factory reset”.  Basically, for  you non-techs, the idea is that sometimes a configuration gets so wrong, so borked, so bad that it’s easier to just reset a device back to how it shipped from the factory and start the configuration process over again from scratch.  I cannot tell you how often I’ve been happy to have this feature and be able to use it.

Of course, sometimes, we inherit these borked devices.  Or we foolishly throw out the two-page manual that tells us how to reset the thing.  Then, we have to go searching for the information on how to reset whatever it is we’re trying desperately to get configured before the weekend, so we don’t have to stay late, again, on a Friday.
Well, wouldn’t it be nice if that was all in one place?  Well, now it is, mostly.  There’s a handy site/wiki called Factory Reset that has most, if not all, of the reset instructions for the most popular and common computer appliances out there.  They’ve got everything from routers to switches to network-attached storage.

So, if you’re wrestling with some device that has gotten out of control, again, why not pop over there and find out how to reset it so you can get out of the office and enjoy your weekend?

No, that’s not spelled incorrectly.

So, back in July, I had the amazing opportunity to go to DEFCON 20 in Las Vegas.  It was quite a historic event; the twentieth anniversary of the biggest, baddest, most talked about computer security convention ever.  Though, of course, I’m using that term somewhat euphemistically.  I heard about DEFCON shortly after getting started in the IT industry and have wanted to go ever since.  Like I mentioned last week, I’m a pretty big fan of sub-cultures and security and, well, DEFCON is the event of the year for an intersection of those two things.  Yes, I’m talking about hackers.

Now, before you assume that I’m off breaking the law, hackers aren’t all bad.  Hackers are just people who think very far outside the box when it comes to things like computers and technology and security.  In fact, most hackers will tell you that they’re interested in improving security by trying to break it.  And, that’s definitely a philosophy I share.  Until you know your security can withstand an assault, frankly, you don’t know how good it really is.
And, as anyone worth their salt at security will tell you, physical access is the first step.  If you can lock people out of your system and keep them from gaining any kind of access, well, that’s a secure system.  If you think I’m exaggerating, well, you’ll just have to trust me when I tell you that the most important data isn’t available from just any networked computer.  To get to it means getting past a locked door.  So, what, then, is the first step in testing security?  Testing locks.

And, yes, while at DEFCON I learned the basics of lockpicking.  It’s not actually illegal, unless I’m trying to bypass a lock to which I do not have permission to test, and carrying the tools for it isn’t illegal, unless I’m trespassing with them, in which case they become burglar’s tools and a different class of felony altogether.  But, I’m only interested in the skill for informational and entertainment purposes.  Trust me.
If you’re interested in exploring the world of “locksport”, there are people who can help and you don’t even have to go to DEFCON to get it.  Just head over to The Open Organization Of Lockpickers‘ website and take a look.  (Yes, that’s TOOOL, for short.)  They have slideshows that explain the basics as well as links to books and sites where you can buy the tools you need to try your hand at lockpicking.  It’s loads of fun!  Honest!

So, go check them out and enjoy your weekend!
(But, don’t call me for bail money if you get in trouble!)
