They just seem to multiply.
The slow PCs, I mean. There’s a never ending supply of the little buggers. Why, if I didn’t know better, I’d say someone was out there manufacturing them! Well, no matter where they come from, TechRepublic has a download-able article to help you: Ten Things You Should Know About Troubleshooting A Slow PC. This one is good for the home user, too, not just the hardcore, corporate geek, like me. Though, honestly, most folks bring their PCs to the Geek at work and have them fix ’em up right, don’t they?
Aw, don’t tell me that I’m the only soft touch!

Oh, and forgive the lame post, but I hesitate to post the stuff I’ve been writing, since I know my ex-wife is reading my blog and might do something else crazy as a result of what she reads here.

Yes, Directory Naming Service needs security.
Oh, my, in this modern, Internet-enabled age DNS security is a larger and larger concern every man-hour. DNS Spoofing, DNS Poisoning, DNS Highjacking, just to buzzword out a few scary key words, are all issues that need to be addressed. And, once again, TechRepublic has an article on it. This time, though, it’s a download: Ten Things You Should Know About Securing DNS. Granted, this is a pretty esoteric topic, but, then again, you’re at the Diary of a Network Geek, where Alpha Geeks come to sniff each other’s… Er, I think I’ve gone one metaphor too far with that one! Besides, with a name like that, did you expect something simple and user-friendly? No, gentle readers, not here. Nothing but the most difficult and challenging questions and issues. (Coming soon: Geek Dating!)
Anyway, best to read the article before someone starts calling your website names.
Take some advice from your Uncle Jim, computer security is nothing to ignore!

Omen or Just Odd?

Filed under: Criticism, Marginalia, and Notes,Deep Thoughts,Dog and Pony Shows,Geek Work,Life, the Universe, and Everything,MicroSoft,Personal,The Dark Side,The Network Geek at Home,Things to Read — Posted by the Network Geek during the Hour of the Rooster which is in the early evening or 6:14 pm for you boring, normal people.
The moon is a Third Quarter Moon

I don’t normally post twice in one day, but…
But, well, this has been an odd week and I had to cancell my therapist appointment last night, so you’ll have to do, eh? As you regular readers know, I was so sick Monday that I wanted to crawl into a hole and die. Alas, I lived through my brush with whatever that particular plague was and had to finally go into work Wednesday. Wednesday, I also found out that I had a quickly approaching deadline to get my house refinanced before we had to start the entire process again. Thursday seemed fine. Until lunch.
Normally, I take my lunch in the backyard and eat while the dog runs and plays. After lunch, I read under my covered porch and let Hilda get some squirrel/bird chase time in. (Relax, tree-huggers! She’s only come close once that I’ve seen and, besides, she’s just doing what dogs do. It’s her nature and a force of evolution. What’s unnatural is the way she loves to eat off my plate!) So, Thursday, I’m sitting there finishing I Heard You Paint Houses and the dog starts to get all strange. I look up from my book just in time to see this giant, bird-shaped shadow sliding over the lawn as the biggest damn bird I’ve ever seen in person starts to make a landing by my ponds! Without any exageration at all this bird must have had a wingspan as large as my outstreched arms! (That’s over five feet, for those of you who haven’t met my manly physique in person.) Of course, I exclaim loudly, which startles this monstrosity into landing on my garage instead. I could hardly believe I was seeing this thing. I mean, I’ve seen big birds before, but, as a rule, even in Texas one does not expect to see a giant, black turkey vulture swooping into one’s backyard.
Now, what got really unnerving about this is that the thing just sat there looking at me. Not scared, really. At least, not of me. Frankly, the dog looked at me as if to ask, “Uh, Dad, care to fill me in on just what the hell is going on here?”, so I doubt the feathery beast was all that intimidated by the dog, either. Anyway, I decided I didn’t like the way this thing was eyeing the pond, or either of us, and I sort of shouted at it to try and scare it away.
It blinked at me.
So, I waved my arms and shouted.
The damn thing just glided up to perch on my chimney and blink at me. It just sat there, this huge ebony carrion-eater with wings, and blinked at me as if to say,”Yeah, and, your point would be, what, exactly?” Then, being bored with me, it looked down the chimney. So, I start looking for small rocks to throw at this thing to scare it off. The first two shots encouraged it to move to the far side of the chimney and, yes, blink at me. Then, I noticed the second one. Oh, great, a mated damn pair of enormous black harbringers of death in my backyard. Looking for a new home, no doubt. I bend down to find more stones to throw and I hear a loud thump. I check and, sure enough, that one on the chimney is looking down inside. At this point, I’m sure I let loose with a string of expletives that would have made a sailor blush because I’m convinced that the damn thing as dropped a dead animal down the chimney. I start looking for more suitable rocks to throw, but when I find them and go to assault the dirty birds, they’ve gone. Just as quietly as they arrived.
Well, at this point Hilda and I look at each other to confirm that the other has seen what we thought we did. (Yes, I know she’s a dog and has limited communication skills, but it’s the best either of us could do on short notice.) Then I start laughing, put her inside, and head back to the office. Once back to the office, I call a friend of mine who happens to work in the Houston Zoo in the bird department to check on what I’ve just seen. He confirms the guess of turkey vultures, expresses a little surprise at the proximity to “civilization” for that kind of encounter, and then he says “Impressive birds, aren’t they?” Um, yeah, sure, “impressive”. Just the word I would have used. Not freaky. Not menacing. Not down right frightening. Nope, impressive fits the bill just right. And then, the day turned ugly.
That’s about when I got the call from our Bellechasse office that they were having problems with the network. After a minute or two of troubleshooting, I can’t see an issue, so, since I’m dealing with a Windows 2000 server, I figure a reboot is in order. Now, see, this is where that black omen comes in. The reboot ends in a Blue Screen Of Death. Hmm, well, that would be a problem, wouldn’t it? So, we kill the power and try again. No joy. I try Last Known Good Configuration with the same results. I try doing the automated recovery, but again, end up with a BSOD. Mind, at this point it’s 4:55pm so I end up calling to cancel my therapy appointment, much to my chagrin, since I had some things to talk about this week. Finally, after all that, I get into the Recovery Console, run chkdsk and repair the error and get back to the original problem. Yeah, I spent 3 hours dealing with a secondary issue only to come back to the original problem. Again, after waiting for someone to come back to that office after making his appointment, which was for a HAIRCUT, and some more troubleshooting, I finally determine that the hub has gone out. The damn hub had died. No moving parts to fail and no power-spike, but the damn hub had failed. And, finally, I drag my sorry butt home at 8:00pm.
This morning, they get some new switches in place, which is no small feat in Katrina-damaged New Orleans area, and, like Network Geek Magicâ„¢, they’re up and running.

Why all the effort not to travel? Because, Monday I have to get a certified file copy of the warranty deed from the Harris County Clerk’s office so I can refinance my house on Wednesday. All so I can save $150 per month. If I stay in Houston past next year. Can anyone, given that turkey vultures landed on my house, the likliness of another hurricane striking Houston, and the not always so great economic outlook for IT guys here in Houston, give all that, can anyone give me three good reasons to stay?
Damn bad-luck black birds.

Wipe Your Harddrive

At least, before you resell it.
It’s always amazed me how many people don’t think about this. Honestly, do you want people you only know through eBay to have your old financial records? Or erotic e-mail you wrote your ex-husband? Or old pictures of you before you started your diet? Or any of a thousand other dangerous or embarassing things that you might leave behind on a drive. After all, all it takes is formatting the drive twice and it should be pretty safe. If you want to get close to government standards, format it nine times. That should pretty well make it impossible to read the old data. For most folks, this really shouldn’t be a big problem, since most folks don’t resell their hard drives, but, apparently, it’s become enough of an issue that the BBC News wrote an article about it.
If you’ve ever bought, or sold, a hard drive on eBay, or anywhere else, read this article. It should frighten you half to death. And, the problem doesn’t stop with hard drives. Any kind of data storage is at risk. Even those memory sticks in that digital camera you sold. Like the idea of your family pictures just floating around out there? Yeah, me neither. So, do yourself a favor and wipe your old data storage devices before you get rid of them. No matter how you dispose of them.

Six Dumbest Computer Security Ideas

Filed under: Advice from your Uncle Jim,Criticism, Marginalia, and Notes,Geek Work,The Dark Side,Things to Read — Posted by the Network Geek during the Hour of the Hare which is terribly early in the morning or 6:39 am for you boring, normal people.
The moon is a Third Quarter Moon

Actually, to anyone in the business, these should be pretty obvious.
Of course, I about read this article on Slashdot, but the Six Dumbest Computer Security Ideas is still worth checking out. I say “still” because getting computer security advice from Slashdot is like getting advice about home alarm systems in the waiting room at a prison. The “real” crooks are somewhere else, but everyone claims they “know someone” and, therefore, have insight. Still, the article is pretty good.
I’m not sure that I agree with point five “Educating Users”. I still that that’s a good idea, but I sure wouldn’t rely on it, mainly because so many users don’t want to be educated about computer security. And, I have to admit feeling a little conflicted about some of the issues raised in point four “Hacking is cool”. Sure, I don’t think we should glamorize hacking so much, but how else am I going to know that my security works if I don’t do penetration testing on it? It’s like a backup, as far as I’m concerned. Until I’ve restored data (ie. test my backup scheme), I don’t know that it’s working. Same thing for my security scheme. Of course, spending a lot of time perfecting those penetration skills probably isn’t the best idea, either.
Anyway, it’s a good article and worth the read if you do any of this at all in your job. Pay close attention to the “Minor Dumbs” at the end, too.

Novell sees Linux as an “opportunity”

Filed under: Criticism, Marginalia, and Notes,Deep Thoughts,Geek Work,Linux,MicroSoft,News and Current Events,Novell — Posted by the Network Geek during the Hour of the Hare which is terribly early in the morning or 6:10 am for you boring, normal people.
The moon is a Third Quarter Moon

Well, no kidding!
When I read this article on the Register about Novell using the upcoming, and potentially bug-filled, launch of “Longhorn” Microsoft’s newest Windows operating system as an opportunity to get their Linux desktop into corporate America, my thought was, “Well, DUH!” What else does this reporter think they’ve been doing?! I mean, c’mon, buddy, this isn’t exactlly a secret, you know? Novell has been talking about this for years. Though, I have to admit, this time I think they have a better strategy, and opportunity, than that “genius” idea to buy WordPerfect. Hey, I love WordPerfect, don’t get me wrong, but there’s just no way that suite of software was going to really compete with MS Office.
Of course, I think they’re being a little optimistic, but, hey, Jack’s heart is in the right place. Hopefully, though, this will keep them alive in the market for a couple more years.
Now, iff they can just hold out until I retire…

Work vs. Personal

Filed under: Apple,Criticism, Marginalia, and Notes,Geek Work,Life, the Universe, and Everything,Linux,MicroSoft,Novell,Personal,Rotten Apples,The Dark Side — Posted by the Network Geek during the Hour of the Pig which is in the late evening or 10:06 pm for you boring, normal people.
The moon is a Third Quarter Moon

They’ve been waiting for me.
I can tell that the folks at my company have been waiting for a guy like me to show up. Today, I had three different persona PCs from three different employees in my cube. Mind, I mean three machines that they brought from home to have me look at for them, not machines from the office. Mostly, they just needed to be defragged and have their anti-virus files updated, but, c’mon, three? Obviously, these people have just been waiting for a “real” computer person to show up so that they can get me to do basic maintenance for them. Actually, come to think of it, I need to update my anti-virus signatures myself!
But, that doesn’t mean I have any less work that’s work related, either. Just this morning I was setting up a PC for yet another person from New Orleans. Which is a good thing, I guess, when you consider some of the alternatives. Of course, it would have been nice if they hadn’t promised that same cube to two different people without telling anyone. I was about to try and move his e-mail from the Windows 2000 machine he had in the office to his G4 Powerbook, but then we decided to take a “wait-and-see” stance instead. With all the miscommunication flying back and forth, we thought that was better. The chaos from Katrina has everyone sort of “runnin’ and gunnin'”, if you take my meaning, and that makes things extra challenging sometimes.
So, with all this craziness going on at the office, I find myself asking, “Should I be doing all this for people?” I mean, it’s not really my job, but the folks asking me to do this for them are the top-level managers. Should I be telling them “no”? I’d really rather not do that, since everyone seems to like me and the work I do for them. Granted, I’m not sure that most of them have any idea what I actually do on a day-to-day basis, but still, they seem pleased, so I’d rather not rock the boat.
Oh, and in recent updates, I did finally manage to get the satellite phone working, but now, since it took so long, we’re trying to return one. Not sure if we can do that at this point, but we’re trying. And, I’ve been messing around with all kinds of Windows 2000, NT and XP issues on the network. Getting all the folks from both offices working has been a bit of a challenge. In fact, if not for the DMZ port on my firewall, I’m not sure I could have had the two domains working together, since they’re named the same. I’m sure that would have caused problems if they’d seen each other on the network.
And, I really should be looking more closely at the version of Linux I want to run on that mythical server that I should be getting spec on. I’m leaning toward either Red Hat or SuSE, possibly even SuSE with all the Novell Open Enterprise Server stuff on it. I have to admit, if I were to get good install media, that could be really cool. All the stability and flexibility of Linux with the way cool administration tools from Novell. Those tools are, after all, what they’re known for developing. It’s the best “value added” product for Linux that I’ve seen so far.
Well, I guess I have some time before we’re really ready to do all that, so, while I wait, I’ll probably just read Sams Teach Yourself UNIX System Administration in 24 Hours, so that my skills are sharp when the time comes. But, now, I’m tired, so I think I’ll just go to bed.

Secure Your Network

In 60 Minutes!
Yeah, I know that sounds a little crazy, but, according to this PDF from the NSA, it can be done. No joke. The National Security Agency doe NOT joke about computer security. Trust me, I would not lie to you about something like that. (Not that I know from personal experience, and that’s the story I’m sticking to!)
In fact, these folks have a bunch of security guides that are freely available on the ‘net. I’m sure the idea here is that computer security is important to Homeland Security which is the biggest buzzword since “synergy”. Whatver the reason, when the NSA offers me security guides for free, I just thank my new governmental overlords and welcome them to my network!

Public Displays of Emotion

Filed under: Advice from your Uncle Jim,Criticism, Marginalia, and Notes,Deep Thoughts,Life, the Universe, and Everything,MicroSoft,Personal — Posted by the Network Geek during the Hour of the Rooster which is in the early evening or 6:06 pm for you boring, normal people.
The moon is a Third Quarter Moon

To emote or not to emote…
Should that even be a question? There are times that I am sorely tempted to, as the old writing aphorism goes, “open up a vein” on this blog and just emote all over the place. God knows, I have plenty to “emote” about. Recently divorced, an ex-step-daughter that seems to think I’m the anit-Christ, mountains of debt, little forward progress in my career recently. There’s lots there. I could go on at length regarding my feelings when packing my ex-step-daughter’s clothes which were left behind. (None of these look like they’d fit her anymore, but they were still hers.) But, I hesitate. Why? Because I know who’s reading this. At least, I suspect who’s reading this. More importantly, I don’t know for sure, but am fairly certain that my ex-wife and her boyfriend (fiance?) read my blog searching for… Well, for something. Honestly, I’m not quite sure what, but they seem determined to find it, whatever “it” is.
So, knowing my audience, or potential audience, or possible audience, how much do I give them? Do I show them a little bit of what I’m feeling in order to show the rest of my readers what my life is like? Do I lie, to throw the pests off the track? No, I can’t lie as a simple distraction. It would feel too ingenuine to do that here. Is it better to drift at a shallow, surface level, never touching the deeper stuff, in the name of “safety”? Not sure I know the answer to that one, either. Though, that may be why my posts have been a strange mix of the personal, obscure and technical lately. Maybe.
Of course, for a long time now I’ve been careful what I say about things and people at work. After all, I would hate to get fired for blogging. Still, there are many things I can, and do, talk about that are quite geekily professional on this blog. It is not, by any stretch of my imagination, a professional blog. It’s very personal, but I do spend a lot of time at work, so work factors into my personal blog. And, I am a geek by nature. For pity’s sake, my older brother has a PhD. in Physical Chemistry and interviewed with Microsoft, in the early days. Know why he turned them down? My brother the chemist, who rearranged molecular bonding sites for his doctoral thesis and wrote shareware for the TI home computer, felt that the guys at Microsoft were just “too geeky”! It’s genetic. Geeks and we both still don’t care for Microsoft. And, yes, I had a great-great-uncle who was in the circus. As a trick shot artist! Still… Strange runs in my family. So, geeky stuff gets into the blog.
Well, have I rambled enough to distract you from the initial premise? Should I talk about my feelings in this blog when someone might either use that against me or take great satisfaction in my pain? Don’t know. If I ever figure it out, I’ll let you know.
Oh, and your Advice for today? “When agitated, pause.” Best advice I never asked for.

PERL OS Detection

Filed under: Apple,Fun Work,Geek Work,Linux,MicroSoft,Novell,PERL — Posted by the Network Geek during the Hour of the Tiger which is terribly early in the morning or 5:10 am for you boring, normal people.
The moon is a Third Quarter Moon

This is sort of the long way around, but…
Well, I have a dream. I dream of a single, giant PERL script that does a complete server inventory, no matter what version of operating system it’s running. Why? Look at my resume. Notice how many times I’ve changed jobs? Every time I hit a new gig, I look at their server documentation, if they have any, and ask how old it is. 80% of the time, no one knows how old it is. The rest of the time, it’s so old and out of date as to be totally irrelevant. Of course, no matter the state of their documentation, it always falls to me to create it or update it. Hence my quest for a single, glorious PERL script that checks everything that matters on an individual server and drops it into a report, or at least a text file that I can make into a report.
The biggest stumbling block to my vision of this splendiferous chunk of code has almost always been the first one: figuring out which operating system the target is running. Well, not any more. No, my faithful readers, including my ex-wife and her new meal-ticket, now I give you Step One in Uncle Jim’s Master Plan for Network Domination.

Well, at least yesterday wasn’t a total waste.
