Diary of a Network Geek

Oy!  This I’m familiar with!

So, I just got an e-mail from my lawyer.  You know, the one who did my divorce just over a year ago?   Well, some time back I did some work on their website, Affordable Houston Divorce Attorney, and fired off a bill to them.  They just got it and got things organized and a check is “in the mail”.  Naturally, things are tight all over, so I’m very familiar with this phrase, but, mainly because I say it so often!

Anyway, I was sure this was going to a black hole that I’d thrown a bunch of time into for no reward, but, suprise!  The check is in the mail!  I guess I can buy groceries and gas this month after all…

I have a dream.

It is a simple dream. No, not winning the lottery, or world peace, or the perpetual motion engine, or even a mythical trip to the Playboy Mansion. No, my dream is that I might get through an entire task without interruption, distraction, mishap, mayhem, or… Sorry, lost my train of thought because the dog started barking at something outside. Now, where was I?

Right, so, Monday, I started out with a few simple bullet items to accomplish. Easy, uncomplicated goals. Just configure a laptop and run a couple of cables out in the shop. Seems fairly straight-forward, doesn’t it? Sadly, those two simple, easy, straight-forward things are still not done, two days later.
Instead, I dealt with spy ware installed on a machine in Bellechasse. A machine that I personally cleaned of spy ware last week. In some cases, deleting, by hand, files and directories and Windows registry entries to kill the offending malware. Two full days I spent on this infernal machine, meticulously cleaning every last scrap of naughty code, only to have it completely reinfected not more than five minutes after it was powered on by the user. Why? Because, no matter how many times I tell my users not to click on any random link they get in e-mail from Bubba Mussolini or Archimedes Hirohito or Kwabena Mieles, no matter how fascinating their offer sounds. Nor should they click on any stupid web page that comes up in a search they can’t imagine would be a problem, no matter how personal it might be. And a guy who’s used AutoCAD for years asked me for help on printing. Me, who’s never so much as opened a drawing in the latest version of AutoCAD, much less tried to send it to a plotter. Naturally, I’ve got him printing in less than thirty minutes.
Then, at home, I made marinara which proceeded to find every piece of clothing I was wearing. That was followed by an attempt at a berry smoothie, made with frozen strawberries, blueberries and raspberries. A smoothie that was so thick and frozen it “poured” like a blender full of half-solid mud. The splash from that minor accident found the clothes that the marinara missed. But, before I could try to stop those stains from setting, I had to hurry and nail up some boards from the fence because my dog had tried to chase a squirrel through the rickety, old thing. Oh, and speaking of dogs, Hilda found something dead and nasty to roll in, after having had a bath Sunday. Now, even though I live far enough away from the city that I pass cows on the way to work, they’re still not in my backyard. Nor am I so close to the projects that she should have found a diaper in the backyard, so what she rolled in, I’m not sure, but, at least now, you have some idea what I was smelling while I tried to get it off her. Again.
(As an aside, I should note that Monday evening, while I was actually having fun installing a blog for a fellow blogger plagued by comment spam, I saw a gecko that was about the size of my pinky scurry across the floor. An hour later, I saw a cockroach by the back door that was at least twice the size of pinky. Who lost the bet with God that allowed roaches twice the size of their natural predator?)

Tuesday, was more of the same, but spiced with visits from phone switch vendors trying to sell me things that I’ve been told I can’t buy. Instead, I have to explain, carefully, to these people that I have two choices for phone switches because a mysterious, invisible “consultant” of some kind, who I’ve never met or talked with, has convinced someone who matters in my company that those are the only two choices that matter. Oh, and the guys in the shop who’ve been waiting on that cable since last week asked about it. And the director of sales needs a photo editor for the Mac he doesn’t want to use, so he can resize pictures to send to clients. And, the engineering department has rehired a former employee, so I need to shuffle people around to get to a computer that has to be totally reconfigured by Monday. (Which is actually an improvement, since I normally get an hour or two’s notice before the guy starts.) And, a giant monitor went out and needed to be replaced. And I have to spec out PCs and a new server, which I’ll have to go install, for that Bellechasse office. And… I’m sorry, something shiny passed by my screen. Where was I?

Oh, right, I should be planning for … Something. Shouldn’t I? Shouldn’t I be planning projects? Planning to improve their IT infrastructure? Something? Who knows. And, what’s more, I don’t have time to worry about it because about the time I have more than two minutes to string together, something else will distract me.
Well, at least they’re still paying me!
But, on the upside, tomorrow night I go in for my last therapy appointment. My head-shrink has pronounced me well. Or, at least, well enough to be turned loose without a keeper, which is all anyone can really hope for, right?

Well, now, if you’ll pardon me, it’s time to head off to work, so I need to put my cup and mouth guard in before I pull on my stain-resistant body armor.
You know, it really didn’t seem like such a big, impossible dream when I got into this business. Ah, well, maybe next year.

Today, I bring you an actual technical tip.

Sadly, it’s not a tip I bring to you via actual experience, but via a regular e-mail I get from the fine folks at TechRepublic. Among the many e-mail news updates I get, they send me a Linux “tech note” filled with helpful information. Today’s was particularly useful, or would be if I were still actively using Linux at work. In the Windows world, a standard setting is to have the Windows password expire every so often, forcing users to create new ones. This usually prompts them to throw out their old yellow sticky note stuck to the bottom of their keyboard, too, but that’s just a side effect of improved security. Now, thanks to this article, you can enable password aging on Linux, too.

Before you start creating users, edit the /etc/login.defs file. Change the following settings:

PASS_MAX_DAYS   99999

(Change this from 99,999 days to something more like 60 or 90. That will force users to change their password more often.)

PASS_MIN_DAYS   0

(Normally, you wouldn’t need to change this.)

PASS_WARN_AGE   7

(This gives them a full week of warnings to change their password. You know your users, but I think “less is more”. Five days should be more than enough.)

You will also want to edit the /etc/default/useradd file, looking for the INACTIVE and EXPIRE keywords:

INACTIVE=14

(This would make an account that has allowed its password to expire to go “inactive” after two weeks. That’s a week of warnings and a week of not working. Should be plenty.)

EXPIRE=

(This sets a specific date for an account to “time out”, regardless of when the password was set. Normally, I’d leave that alone, but if you really want to set it, it’s done in the format YYYY-MM-DD.)

That should get you through most “normal” situations, but if you’ve already got existing users or want more information, read the article at Tech Republic.
Wow, that was fun. For me, at least. Now, all I need is a job that lets me actually use those Linux skills that are rusting like a horse-drawn plow in the Winter snow….

I really don’t mind flying with my boss, but I wish he’d stop saying that.

So, Thursday last week, things started to go wrong with our server in Bellechasse, or, as I think of it, the Sweaty Armpit of the Gulf Coast. First, it was a user who just couldn’t seem to connect. Then, there was another user who couldn’t connect, though that turned out to be a totally unrelated problem. After dinking around with the server and the workstation over the phone, we finally rebooted the server and the problems seemed to be solved.

Turns out, not so much. Friday I got a call shortly after 8:30AM letting me know that now four users can’t connect to the server. So, again, after a few minutes of screwing around with a work station, I had them reboot the server, figuring that what worked the day before should work again. Seems like sound logic, right? Well, it is a Windows 2000 server, so logic probably wasn’t the best tool to apply. Everything seemed fine, right up until the server hung up at the “Preparing network connections” message. We rebooted the server at least three times after that and even tried Safe Mode, but, to no avail. So, I broke the news to my boss who was barely able to contain his joy at having an excuse to fly.

I should mention that I’ve flown with him on several occasions without incident and, as far as I can tell, he seems to be a very fine pilot. Certainly the flight itself has been smoother than most commercial flights I’ve been on. And, being able to bypass any sort of security checkpoints or limited schedules is really nice. It means, generally, that I can fly over, fix the problem and fly back in the same day. All with out needing to fill out an expense report, I might add.

So, well before sunup on Tuesday, we flew over to a little flat spot on the edge of New Orleans they call Lakefront Airport. This trip, I noticed that the same roofs seemed to have the blue FEMA tarps over them, but more yards had the pre-distressed FEMA trailers in them. Not sure if that’s progress or not, but, somehow, it seems like it should be. At least more of the traffic lights were working. Certainly, that has to be considered progress.
In any case, we got to the office about 9:00AM and I walked right to the server and got to work. I started by rebooting, just to see if I was going to get lucky. Naturally, I wasn’t or this post would’ve just ended. So, I cycled through several different boot options and finally, after much weeping and wailing and gnashing of teeth, I got the server into a semi-stable state by booting into Safe Mode with Networking Support, but via the Repair Mode on the Windows 2000 install disk. (No, don’t ask me to recreate the steps because I wasn’t taking notes and I was probably running a fever.)

So, guesses on what was wrong? Out of disk space. Or rather, there wasn’t enough disk space for Active Directory to run properly. So, I killed a bunch of temporary files and cranked down on the size of the virtual memory paging file. Sure enough, when I rebooted into “normal” mode, the server came up and everyone was able to log in and all was well with the world. All done before lunch, I might add!
And, so it was that I humbly asked to be brought an oyster po’boy, dressed, sans tomato, with fries for lunch while I attempted to kill all spyware and adware and other such nastiness. What I got was a catfish po’boy, two hours later, and one machine that still has some spyware remnants on it that need to be cleaned up. How fleeting is glory… Oh, and that’s not to mention the several requests I got that were far, far outside the scope of “fixing problems”, which was, in fact, my stated purpose.

Interestingly enough, when we touched down again in Houston an essential piece of navigational hardware in the boss’ plane locked and threw an error message. Then, up popped the infamous Windows NT “Blue Screen of Death”, upside down on that oh, so essential monitor. Yes, boys and girls, our lives depended on hardware that runs the most unstable, buggy, crash-prone version of Windows I’ve ever worked with.
Yeah, we sure cheated death again. Barely.

(Note: This “post” was written over the space of two long waits in airports after gliding through easy and over-hyped security.)

08/11/06

Well, there wasn’t any free wifi at the airport that I could find, even using a cool new tool I found for Linux called Wifi-Radar. Super slick little proggie that scans for available open wifi networks and automagically attaches you to the network of your choice. Pretty cool. Anyway, security was a breeze. As usual, the blood-sucking, bottom-feeders in the alarmist media totally overhyped the delays. I got Hilda checked in, stopped for gas and slipped into the Park-N-Fly by about 10:45 AM. The shuttle got me to the airport no later than 11:15AM and I was checked in and through security in less than 20 minutes. That’s with an eTicket and a driver’s license that still has my last name misspelled with an extra letter. You’d think that would raise a red flag, right? Hell, it doesn’t even raise a damn eyebrow.

Feeling extra secure yet? So, we hear all kinds of stuff about how bad security is going to be, but, as far as I could see, the only thing added to security was that they were restricting fluids on the plane. Yeah, so, no drinks through security, which, of course, means that everyone was buying drinks in the terminal. I didn’t look at how much I was gouged for my bottle of water and masked the whole cost with a couple of magazines. No Maxim, though. Just PopSci, Scientific American, Men’s Health and Real Simple. You know, I may end up getting a subscription to Real Simple instead of Dwell. It’s more my style. Not quite so avant-garde and infinitely less expensive. I was very glad to have gotten my iPod back, though. And, I even managed to sync all of Tristan und Isolde to it before I took off in the morning. Sadly, I didn’t have quite enough time to create a playlist that let me listen to the entire opera in order, but, still, I have it in there. According to iTunes, I have almost three days worth of continuous music on my Nano. Based on the silly media hype, it sounded like I’d need it, so, I was thrilled.

The one interesting thing was that I was almost on the news. No, not because I tried to sneak something dangerous on the plane. Though, God knows, I have done just that so many times it really makes me question the supposed security training they give those TSA agents. Anyway, there was some cute, Hispanic news chic there with her cameraman interviewing passengers about the virtually non-existent security delays and they saw my “Sunguard Secure, Disaster Recovery Experts” shirt. Right away the camera guy is all “So are you a disaster recovery expert?” and I start laughing at them both. I explain that, yes, I am an IT disaster recovery expert, but not the kind they were looking for. Oh, sure, I could have gone on TV and made a credible security expert, but that’s mainly because I’m well read and I’ve spent a lot of time thinking about security for IT, which includes physical security, not because I’m a real anti-terrorist expert. But, why? Why the hell would I want to have my mug all over the TV news? I hate them, the alarmist fear-mongers always whipping the mass of unwashed humanity into a damn frenzy. Idiots. They’re not journalists anymore, just talking heads. It’s all about jumping on that fear-hype bandwagon, not about reporting real information that people can actually learn something from anymore. I don’t know, maybe it’s time to get a subscription to a local paper again. Ha! “A” local paper, that’s funny, isn’t it? It’s either the Chronicle or an out of town paper, like the Chicago Tribune or the Wall Street Journal. Oh, well, it’s almost all bad news anyway….

08/14/06

Well, here I am again, killing time in an airport waiting for my flight after breezing through security. I can’t tell if it’s just the media blowing things so far out of proportion or just people stupid enough to argue with the TSA agents and trying to break the rules. Honestly, I think it’s the TV news media who have to justify their existance by whipping everyone into a frenzy about the terrorists who weren’t even on US soil. Sure, I’ll grant you, getting blown up in a plane would really ruin my travel plans, but we’ve been living with this since 9/11 and, frankly, I think it’s about time we just adjust to higher security than we used to have. I mean, really, compared to most of the world, we’ve been skating along pretty free and easy. They’ve been dealing with terrorists in Europe for years and the British were more relaxed about this last incident than we were, even though it was their countrymen that were going to be blown up! This is just going to be a fact of life from now on. We need to get past the panic and fear and make our adjustments and move on with our lives, otherwise the terrorists have already won. So, in any case, I glided through security, in spite of not shaving, having a scruffy goatee and being loaded down with electronics. I guess it helps to just blank your face and go with the flow. Not like I have a choice, after all, so I might as well just accept the process and go with it. Seems to make things a lot easier. So, crazy security concerns aside, I had a good visit with the family.

Turns out, my parents were wrong and I wasn’t going to be presenting my nephew with his Eagle award, but it really did seem to mean a lot to him that I was there. Actually, it seemed to mean a lot to everyone to see me. I guess I shouldn’t be so surprised, but I never realized how important I was to my family. Of course, I spent some time setting up my parent’s new laptop and transferring settings and files over from the old one. I first thought that I’d be able to do that via a USB thumb drive, but there was just a little too much there to get onto a single one gig drive, so I had to use the network cable and crossover adapter that I’d brought with me. Good thing I have a little bit of experience being an IT consultant on the road and thought to bring some “extra” stuff I probably wouldn’t need, just in case. Sadly, I forgot to bring the copy of Word that I had for Mom and scratched the first CD of the Works install set, so I’ll have to ship them the CD and walk Mom through the install. Oh, the funny thing about her new laptop is the wireless connection. I cranked up that laptop and found five or six networks in the area with at least two that were unsecured, so I used that to piggy-back to the Internet. I think that ease of use just about convinced her to invest in broadband at their new house when the finally move in. They already have digital phone service through their cable, so I’m pretty sure they’d get a discount on the Internet connection, too. That along with a wireless router would really have them in the modern age of computing. And, I think they’d use their laptop more. Well, at least, Mom would. Dad mainly tells her what he wants and sends her off to do it, but he thinks he’s pretty high-tech, which is kind of funny. Actually, if you ever met either of my parents, it’d amuse you think of either of them being all that high-tech.

Though, somehow, they turned out at least two of us that make our living via technology. That’s just one of many things my brother and I have in common, though… It was nice talking with him some, though, I think we both wouldn’t have minded talking more. Eleven years apart and a vast difference in life experience, but we’re still the same in so many ways. Sadly, we both have many of the same things to fight through and over come. Both shy, each in our own way. Soft-spoken, but determined and, often, very single-minded of purpose. I honestly think that my brother has a PhD. because someone told him he couldn’t do it. We’re funny that way. Sometimes, that’s an asset, but not always.
Still, we often have very similar political views and, talking with my sole niece, Rachel, I was surprised to see how well our philosophies about kids meshed. That “little” girl has grown into quite a young woman. Just barely fifteen, but almost as tall as I am and, thankfully, looking more like her mother every day. I sat with her after her brother’s Eagle Ceremony and talked with her a bit, since I realized I didn’t really know her that well these days. The boys all center on me like iron filings on a magnet and that often seems to leave little room for Rachel. The last time I was home, she spent most of the time with Allison, my former step-daughter, and I didn’t get to talk to her. In any case, I took the opportunity to chat with her about a lot of different things, including driving, boys and her future plans. She didn’t have a boyfriend right now, but she’s already had two, which, at fifteen seemed like a good, slow start. She broke up with the last one, she told me, because he’d been smoking marijuana. Smart girl. Already learned that guys who smoke enough dope lose all motivation and ambition. It’s not just a stereotype. So, she was single, but didn’t seem in a big hurry to find the next guy, which I though was a good attitude, too. When I asked her about school and ideas for a career, she told me she wanted to go into nursing. Like I said, smart girl. It’s a good field and she has the right kind of personality for nursing. Even at fifteen, she was worried about her poor, old Uncle Jim standing when everyone else was sitting at the reception. I was glad for the chance to sit and talk with her. I just wish Allison had more of an opportunity to know her former cousin. I think Rachel would have been a good influence on her. Ah, well, maybe they’ll reconnect one day. Stranger things have happened.

Her little brother, Michael, my youngest nephew, is a whole different animal. This poor kid has no small amount of adversity to overcome. As a little guy, he got repeated ear infections and is, as I recall, legally deaf. But, since he was very small, he’s worn a hearing aid in each ear and does quite well. He has a very slight speech impediment, but he seems to make up for that with enthusiasm and volume. He certainly has no trouble making himself understood when he wants to get a point across! But, he also has a fairly rare back and spine condition that will require him to wear an obviously uncomfortable back brace for most of the next three years. He’s a good kid and doesn’t complain much when his parents tell him to get his brace back on, but it can’t be something he likes to do. I don’t know if any of the kids at school give him trouble for it, but I think his mother has already given her permission to pop the little wiseasses if they do sound off. And, if I ever hear about any grief, I tell you, Mike will have a mean uncle from Texas coming up to crack a couple of skulls for him. He’s a good boy and puts up just a tiny fuss at having to deal with all his physical troubles. And, in spite of all his reasons to be unhappy, I’d say he’s the most gregarious and, well, “jolly” of all my nephews. Always smiling and laughing and joking, even when irritation occasionally creases his forehead, it sure doesn’t cloud his world for very long at all. I know quite a few adults that could learn thing or two from this young man.

Then, there was my “redneck nephew”, as I like to call him.
John Dwight is a big kid. He looks slow and ponderous and even sounds a little thick, but he’s not. He’s a smart kid who lives in a town that doesn’t put much stock into “book learnin'” and it shows. Mainly, I think he’s just not very motivated. I think he sees the futility of his situation. He can only go so far in that little town outside of Rockford, Illinois. After that, if he wants more and bigger opportunities, he’ll have to leave. Based on how his mother and father have dealt with that decision, I doubt he’ll leave. Though, he is talking about enlisting in the military. He claims he wants to be a sniper, but with less than perfect vision, I think that’s not going to quite work out for him. He likes to work on cars, though, and seems to think he can bide his time waiting for the sniper program while being a mechanic. I don’t think he understands the military enough to know that once he starts as a mechanic, he’s likely to stay a mechanic, but, at least he’ll have a skill and a way to make a good living after mustering out. It would be a good way for hime to go.
He shadowed me for most of the time I was working on my Mom’s new laptop. I think partly because he wants to get a shiny, new laptop himself, but also because he’s interested. I talked with him about what I was doing and promised to send him one of the super cheap 1 Gig USB thumb-drives I’d found at MicroCenter and was using. He seemed genuinely excited about that. I’ll send that to him after I get back along with a Knoppix CD, so he can learn a little Linux. If he learns Linux and is still interested, I might send him an old Dell laptop with Redhat or Novell’s free OpenSuSE loaded on it. That would be another direction he could go. A little military experience and a couple of professional certifications and he could really go far.

Finally, my oldest nephew and godson, Bill…
As I write this, he’s on his way to his first year of college. He’ll be a Physics Major at Purdue University. Kid’s going to be a genius PhD, like his father. He has a girlfriend, Jenny, who’s nice enough, but tries a little too hard to be liked. When she forgets to work at it and relaxs, though, she’s a nice kid. Bill and I had a little talk on Friday night when his family came over for dinner. (Mom made “creole chicken”, a soulfood recipie that my grandmother picked up on the Southside of Chicago.) He’s so much like his father that it’s almost scary. I was touched Saturday when I figured out that he really just wanted me at the ceremony because he missed his Uncle Jim. I made sure to give him my cell number and told him he could call for anything but bail money. I hope he takes me up on the offer. I gave him the best advice I could for a Freshman going into that big, wide world of college. “Never go into a weekend without twenty bucks and a condom.” I explained that to him, but those stories will have to wait for another time on the blog. My plane is boarding, so I’m shutting down the laptop. Next stop, Houston!

Update:
Made it home safe and sound. Got my poor Hilda from the vet today. Apparently she barely ate, hid from the “keepers” and generally trusted no one. On the upside, she did learn to use the “doggie door” really well! That’s where she ran to get away from the people who were supposed to pamper her. *sigh* She wouldn’t even eat her home-made treats. Apparently, she just didn’t trust the kenel staff enough to take even the yummiest of muffins from them. (In fact, they said they smelled so good they almost ate some themselves!) She was so excited to see me, I could barely get her car harness on her. She wolfed food when we got home. And treats. And attacked a new rawhide chewie bone I’d gotten her. Well, she’s like her old dad, doesn’t trust anyone new and is loyal to a fault. She’s my dog, sure enough.
Glad to be home. And, finally, after all this time and all this trouble, this is home.

Advice from your Uncle Jim:
"When trouble arises and things look bad, there is always one individual who perceives a solution and is willing to take command. Very often, that individual is crazy."

Today is System Administrators Appreciation Day.

Today is a day set aside to give thanks that either: a) someone else manages your servers, or b) you have servers to manage. It’s not an official holiday, yet, but, much like “Administrative Professionals” Day (aka Secretaries Day), it’s a day to think about the “little people” that make your job possible. This is the seventh annual System Administrators Appreciation Day and, to date, no one has done a damn thing for me. I’m so unloved.
Actually, that pretty well sums up my life in IT. I’m the glue that holds the network together and virtually no one knows, notices, or understands what I do. Well, at least I have this small and hollow comfort that someone, somewhere cares enough to setup a webpage dedicated to guys like me.
Thanks.

Anyhow, it’s Friday and your sysadmin has kept the network running long enough for you to read this, so you might as well click on this link and get him something nice for next year! (If your wallet is feeling up to it and you want to show me how much you appreciate my work, you can get me something from my ThinkGeek Wishlist. Hey, a guy can dream!)

No, not the traditional dangers.

Most outsourcing is done to countries other than our own. At the moment, the majority of our outsourcing goes to either India or the Pacific Rim. (For those of you who don’t follow this sort of thing, the Phillipines seem to be the next “hot” market, sucking away significant portions of India’s outsourcing revenue.) Sure, the prices are right and, depending on the type of outsourcing, the work might even be comprable to what you’d get in the States, but what about the other dangers? When was the last time we had a tsunami? And how long has it been since we had a major bombing here in the States? Now, I’m sure some of the people who stumble across this blog searching for information about outsourcing to India or the Phillipines or where have you will call me a racist. I’ve been called that before when I said I thought American companies should give American workers jobs before sending them offshore. But, I promise you, nothing could be further from the truth.

Still, I find myself remembering the mortgage company I worked for when I first came to Houston. We employed a small town in the rural United States to be our phone center. That job could have easily been sent offshore to an outsourcing company in Mumbai or New Dheli or Manila. But, it turns out that it was just as cost-effective to employ American workers. Also, we never had a complaint that our customers couldn’t understand our phone center workers. Now, keep in mind, I’m just being realistic here. Not everyone who speaks English as a second language has an impeniterable accent, nor is being a native speaker any guarantee, either. But, that little town was safe. No worries about things like tidal waves or bombings or coups or even hurricanes. Even blizzards didn’t stop them, though they did slow down a little the times they got hit with that. Still, they were safer from a disaster than we were in Houston and still enjoyed the comfort of knowing that the United States was a stable government who kept the peace in their own borders. Yes, we’ve had our share of tragedy, but, mainly, we’re a safe place to live and work. Safer than most of the world, really.

So, tell me again, how is this outsourcing, offshoring thing such a good deal?

No, not me or anyone I know.

Sorry, but most of the geeks I know either simply are not “hotties” or are men and, well, I just don’t see them that way. And, of course, with the way my negative weight-loss has been going, I’m far from that myself. Still, rumor has it that they’re out there. Certainly, it seems they’re in Australia. At least, if this article about a Hot Geek chick calendar on AustralianIT is to be believed. Certainly, the website for the calendar itself, IT Screen Goddesses, seems to be legit. At least, they’re selling calendars of beautiful women. But, what’s their “geek cred”? Do they run Linux? Are they programmers? That I cannot say from the article or website, but, well…

Okay, this just struck me as funny. I apologize in advance to any of my readers who might, possibly find this demeaning in any way. And, you have to give them credit, at least they’re highlighting beauty and brains, in a single package. Surely, it’s no surprise that such things can coexist to my female readers, but it might shock some of my more sheltered male readers.

So, now that I’ve ruined my chances with any hot chicks who read this blog, you might as well click on the links and get chuckle. It is Friday, after all.

An old “trick” that never seems to get old, even when it doesn’t quite work.

Every once in a while, I actually talk about technical stuff on this blog and this week, I’m focused on Google. Oh, sure, it’s called “Diary of a Network Geek”, but I generally talk about all sorts of geeky things that have nothing to do with computers or networking at all. Well, today you get a treat, gentle readers, and I’ll write a little technical bit about what this is and how it works, or doesn’t. Here’s the trick, in a nutshell: Google a specific site or page with no extra parameters, using the “site:ryumaou.com” syntax. (To hit a specific page, “site:ryumaou.com/hoffman/netgeek/“) When you get your search results, notice at the bottom of each description, there is a link labelled “Cached”. Click that and you’re looking at the page as it resides on the Google servers. At this point, normally, you’d not be hitting the actual website at all, but simply viewing the page as it was stored on Google’s servers when they spidered the site for their search database.

Now, normally, that would hide you from a web log, but not from this blog. Why? Good question. What you see pictured in the graphic on this post is a rookie mistake. Googlecache browsing doesn’t work well to conceal one’s IP address when browsing dynamic content. I know it might not always seem like it, but this blog is, actually, fairly dynamic. In this particular case, what tripped up our inexperienced sneak is a plugin, or set of plugins, running on the blog. Mainly, it was the plugin that makes the pretty title graphics via PHP. When our tricksy, little Hobbit hit the Googlecached page, his browser made a call directly back to code stored on my site to generate the cool graphics. Graphics which, because they are generated dynamically, are not stored in Google’s cache, but created “on the fly” every time someone hits my page. Interestingly enough, even if our erstwhile intruder had turned off the ability to view graphics in his browser, the PHP code would have still generated graphic, thereby alerting me to his rather weak attempt to conceal his identity.
The only thing one might gain from this “hack” is the ability to get around a blocked IP address. Sadly, the sneak doesn’t need to do this, as I block very few IP addresses at all. For one thing, an IP block is of limited value for blocking spammers, since they change IPs regularly to avoid such blocks. For another, to deal with spam and other unwanted visitors, I have other tools that work much better. So, really, all this particular tricksy, little Hobbit did was, well, waste their own time and give me a handy topic to write a quick piece about very basic web security.

So, um, thanks. Now, c’mon in from the cold and just browse the site to your heart’s content, okay? Oh, and don’t forget to vote on the poll in the sidebar there everybody!

Advice from your Uncle Jim:
"When in doubt, don't."

I highly reccomend checking yourself on Google.
Why? Because your next employer may be Googling you, that’s why. At least, according to this article on the New York Times, that’s what’s been happening.  I certainly know that I’ve been found on Google on more than one occasion.  Not only by employers, but also by potential dates and, well, obviously, dates.  This blog did, after all, start as a marketing scheme, a way to get the search engines to find me and catalog me.  It worked.  Very well, in fact, as this page has a Googlerank of Five out of Ten.  And, if you Google Linux Resume, I’m the second hit.  If you Google CNE Resume, I’m the first two hits.  If you Google Jim Hoffman, I’m the sixth hit.  So, I think about what I say here, and how I say it, because I know people might actually read it.  People I might care about and people who’s opinion matters to me or can effect my life.  And, I’m told that in the dating world, it’s more and more common to Google potential dates to see what mischief they’ve been up to on the web.  Obviously, one never knows what might turn up.

This is a special concern for bloggers, of course, who put themselves “out there” on a regular basis.  Do you want a potential employer reading that last rant?  Or about your after-hours antics?  Or about the slacking you do at work to post to your blog instead?  All things to think about.  So, what do you find when you Google yourself?  If you don’t know yet, maybe you should try it and see what turns up.
