Diary of a Network Geek

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…

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…

In honor of the first Friday of NaNoWriMo, I’m bringing you a free writing tool and not from my usual main site.

This week, I’m originating my regular Friday Fun Post from JKHoffman.com, where I hope to move most of my more creative work, instead of my regular Diary of a Network Geek.
If you’ve given serious thought to writing, you have probably heard of both National Novel Writing Month, AKA NaNoWriMo, and a writer’s program called Scrivener.  Personally, I’ve done most…

There are more free sysadmin tools for Windows than you can shake a memory stick at these days.

But, here are a few of the better collections of them.
First, from Infoworld, 15 “Essential” Open Source Tools for Windows Admins.  I’m not sure I’d say these are all essential, but they are a pretty good start.  I can only vouch for three of them on this list; Wireshark, Nmap, and ClamWin Antivirus.  Though I’m familiar with them from the Linux/Unix world, these are the Windows equivalents and they work just fine.  Old network geeks will recognize Wireshark and Nmap as a reliable packet sniffer and a security vulnerability scan tool, respectively.  You may not be as familiar with ClamWin.  It’s based on the ClamAV engine, which in its Linux boot-disk incarnation, has saved my bacon more than once!  There are a couple inventory tools in this list I plan on looking more closely at, not to mention the add-on for Nmap they talk about.  Good stuff and worth checking out!

Secondly, from TechRepublic, there’s Five Free Windows Registry Cleaners.  Again, I’ve only used two of these five; CCleaner and Wise Registry Cleaner.  CCleaner does everything I generally need in regards to shoring up old, creaky registries, but I’m always looking for new tools.  The version of Wise Registry Cleaner I used was an older one, but it worked well enough.  And, it does have the nice feature of being able to backup and restore older versions of your registry.  Believe me, that can come in handy sometimes!

Thirdly, also from TechRepublic, Five Microsoft Tools to help with Server Management.  Of these five, again, I’ve only used one; dcdiag.  Naturally, it’s the only command-line tool in the bunch.  Though, I hear Microsoft has been talking about going back to a command-line, terminal interface for their server products.  I’m a little leary of any security utility that is based on a wizard, but I have to admit, at least it’s something that might encourage Windows sysadmins to do some work at securing their servers more.  And, I have to admit, I wish I had known more about the file server migration wizard a few years ago.  It sure would have helped me more than once!

And, finally, the venerable, but ultimately useful, More Sysinternals for Windows Admins.  Now, these I’ve used quite a bit!  At least, some of them.  All the disk usage utilities have been super helpful over the years in determining who has been sucking up all the drive space on my servers!  And I’ve used PsInfo to attempt to gather information in various attempts to inventory my various networks.  And, these days, everyone will need the RootKitRevealer sooner or later.  Sadly, almost everyone has been, or will be, effected by a rootkit virus of some kind.  It seems inevitable.

So, there you go, system administrators.  There’s my gift to you in the form of links to tools to do your jobs, faster, easier and more efficiently.  Enjoy!

I love free!

So, most everyone in my business has heard of Adobe.  Mainly because they’re the top design and graphics software publisher in business right now.  Well, they’ve released a FREE program called Muse that lets you layout and publish webpages without having to write code.  Now, myself, personally, I’m okay writing the HTML code behind simple webpages, but, frankly, it’s a lot faster to do it in a nice graphical user interface that’s filled with point-and-click tools.  Also, since this comes from Adobe, you know that they’re going to have a great interface and make it easy to use for the novice.  Not sure how the output is, but, frankly, for most users, as long as the page looks nice when they’re done, the code behind it doesn’t really matter.

The program itself runs on their Adobe AIR platform, which means it’s pretty lightweight and fast.  You can read about all the features on the Muse website.
Oh, and while this is free right now, it will, eventually, be for sale in 2012, when they’ll be charging by the month for it.  So, you’d better get this while you can!

Hey, free, creative software just in time for the weekend, how can you beat that?
Well, enjoy your Friday, in any case.

No, not a cad program by the flat-pack king.

Rather cad files of 21 of IKEA’s designs.  Yep, now you can suck those ubiquitous IKEA designs right into your high-end architect’s cad program and use them to design your house.  ‘Cause, you know, after paying for an architect in this economy, how much money are you going to have left over for fancy furniture?

No, seriously, I just thought it was fun that someone had made cad drawings of IKEA stuff in 3D so you can use it to lay out your house or apartment.  The files are actually in Google Sketchup format, for guys like me who are always trying to do more with less, especially less expensive software!

Speaking of free software…

Many of you know that I’ve long been a proponent of the spectacular free office suite, Open Office.  Well, there’ve been some shake-ups in the free software world and Oracle and the developers of Open Office have had a bit of a falling-out.  Nothing too serious, really, but enough of a difference of opinion about the future of Open Office that they forked the project.  Now, what that means to you and me is that they’ve taken the open source code to date and started their open development of it under a new name.  The new project is called “LibreOffice” and is being supported by the Document Foundation, who’s sole purpose seems to be continuing development of this fantastic office suite.
Follow that link and you can download the latest version to try for yourself.  I suggest you do because you may never buy another revision of Microsoft Office again.
Seriously.

Yeah, I know, I’m not really a huge fan of Micro$oft Office either, but, what can you do when it’s become the defacto standard?

Make the most of it!
So, back in the day, the reason I originally got into computers at all was due to writing.  I know, crazy, right?  Well, I discovered how much easier it was to edit documents without having to retype the whole thing and I was hooked.  Then, as I wrote more, I got really into moving whole sentences and paragraphs and, yes, even entire, multi-page sections of text from one part of my work to another.  It was pretty fantastic, really.  In any case, copying and moving text is one of the things that Word is really good for and there’s even a secret feature to make your editing job easier; The Spike.
With the Spike, you can copy or cut multiple sections of text and then paste them all into the same section all at once!  You can even take text from multiple documents and copy it to the Clipboard and then paste it into a new document with the Spike!  How fantastic is that?

So, go check out the link and see how to leverage all that power for yourself.
Enjoy!

Remember, these are “administrator utilities” not “hacker tools”.

In my business, it pays to make the distinction.
When people call me for help outside the office, the calls usually fall into a couple categories; a virus, a slow computer, a lost password and “how do I do X?”  Sadly, I’ve been doing a lot of virus and spyware removal, but, also, lately, I’ve had a couple of “lost password” calls.  I actually love getting those, for a couple reasons.
First, lost passwords are surprisingly easy to recover if you have physical access to the machine.  It’s funny to me how few people get that.
Secondly, I find recovering passwords fun.  In a way, it was one of the first things that drew me into the business.  I was one of those guys who got hooked by the security bug not by War Games, but by Sneakers.  Yeah, I know, most guys my age especially will tell you it was War Games that really got them hooked.  What can I tell you?  I’ve always been kind of a late bloomer.  And, my dirty, little secret is that after seeing Sneakers, I wanted to be Marty Bishop.  Seriously.

Anyway, my recent experience with Windows password recovery requests gave me an opportunity to refresh my tools.  After Googling a bit, I found a handy About.com page titled “Top 6 Free Windows Password Recovery Tools“.  I downloaded several, most of which were based on bootable CDs of one kind or another.  I like those kinds of toolkits because they don’t require even limited access to operating system, just the ability to reboot the machine from the CD toolkit.
In the end, I tried two; 0phcrack and the Offline NT Password & Registry Editor.

Now, I’m not positive, but I’m pretty sure that 0phcrack is the free, opensource fork of l0phtcrack.  Now, for an old-timer like me, l0phtcrack was THE password cracker to have, back in the day.  Created by a group of well-known hackers, some of whom famously testified before Congress, it was not free.  At least, theoretically.  If you knew where to look, you could get copies.  And, yes, I  them.  But, this version IS free and seems like it had some improvements.
For one thing, the old version had a slightly clumsy text-based interface.  This version has a much nicer interface that seems to use X-Windows.  It’s also far more intuitive to use.  It ran pretty fast, really, though, sadly, didn’t seem to be able to crack the non-dictionary word used as a password on the Windows 7 box I was using it against.

On the other hand, the Offline NT Password & Registry Editor has been around for several years, and had several updates, though it retains the text-based interface.  I don’t remember when I used this the first time, but, so far, it hasn’t let me down in a pinch.  This time was no different.  So, yes, even though it has “NT” in the name, I’ve used it on everything from Windows 2000 through Windows 7 without a hitch.  Of course, your results may vary.  The bonus of this product is also it’s most potentially dangerous drawback; it directly edits the registry and password files.  This is dangerous, in a way, because if something goes wrong, this could, theoretically, lock you out of your machine permanently.  In practice, this has never actually happened to me.
One advantage of this utility is that you can change or simply remove the password for any active user on the system.  Also, you can use it to promote an active user to being an administrator equivalent.  Now, by “active user” what the developers mean is any account that is not disabled.  Though, I think there may be the option to activate a deactivated account.  I’m not positive, though, because I’ve never had to look for it or try to use it.  And, yes, this worked like a charm to simply blank the password on the Windows 7 machine that had apparently forgotten its own password.

So, there you have it.  Two tools to recover lost Windows passwords.
Oh, and, just a quick disclaimer here.  I’m not responsible for any damage you might accidentally do to your machines with these utilities.  Nor am I advocating using them to break into your ex-spouse’s computer to read their adulterous e-mail to their lover.
I’m just sayin’….

Hey, I missed letting everyone know about System Admin Day this year, but, I think this will make up for it.

I’ll be honest, one of the reasons I missed that this year is because I’m so overworked and over-stressed it’s like I was married to the Queen of the Damned again!  Seriously!  I haven’t been this frazzled since my divorce!  In any case, I imagine there are a lot of other server administrators out there with less free time than they’d like, too.  So, I’m sharing a blog post from Tech Republic; 10 Must Have Windows Server Tools.  I don’t know about “must have”, but they are handy for Windows admins, anyway.   I’ll need to scout around and find something similar for Unix admins.  After all, I can’t forget my bearded brethren!

So, hope that helps free up some time for you all, but now I’ve got to get back to work!
