Right, so you know I love Linux, right?

But, beyond that, I love all the bootable tools and utilities and things that Linux let’s you do to Windows machines.  Well, there was a time I carried several “flavors” of Linux on various USB keys in my pocket, depending on what I wanted to do.  In that spirit, I have another tool to create Linux USB Keys for you; LinuxLive USB Creator

It’s a free, Open Source utility for Windows that let’s you create live USB keys running Linux.  The link will take you to the download page on SourceForge.

If you’re a geek like me, it’s worth a look!

The Ultimate Home Network

The moon is a Full Moon

A pretty bold statement, isn’t it?

Well, I’m not going to tell you how to build the “ultimate home network”, but, rather, suggest some things that you may want to consider to build your own, personal, “ultimate” home network.  Everyone needs something different from a home or small office network.  Some of us have side jobs that require a fair amount of data transfer or storage, like, for instance photographers.  For some of us in the IT business, having a home “test” network is almost assumed, though, perhaps not as much as it used to be in the boom days of the Internet.
I’ve been thinking about it this past week because my old BorderManager firewall finally has died.  I’m using a backup firewall at the moment, which is “good enough”, but I’ll be taking this crash as an opportunity to start rebuilding my home network from the ground up, using mainly free, open source software, starting with a Linux firewall.  In fact, I have three that I’ll be looking at and, yes, writing reviews of, in the coming weeks.  This will be an on going series of posts, too, as I evaluate software and, piece by piece, integrate it into my working, live network.  My needs will probably be different than yours, but all home networks will have some similar items and considerations.
So, what should go into your own personal, “ultimate” home network?  It depends on what you do, but here are some ideas.

The Actual Network.
Obviously, the first thing is setting up the actual, physical network.  And, in this case, by physical, I’m including wifi routers and the like.  Back in the old days, having a home network meant running cable.  That’s not as true as it used to be, but don’t just go wireless without considering at least some wired connections.  If you’re concerned about security, for instance, especially, regarding financial transactions, nothing is as secure as a wired connection.  Keep in mind, though, that at some point you still connect to an outside source to get to your bank.  Also, since most laptops have built-in wifi and have gotten so inexpensive, if you don’t already have one, consider getting a laptop.  For most people, laptops can inexpensively do everything we need to do and have the advantage of portability, so if you need to leave, say in case of a hurricane, you can take at least part of your home network with you.
There are a wide range of network switches and routers out there to choose from, but I suggest sticking with a name brand that is relatively well known and established. It’s no guarantee that you won’t have problems, but it’s a good start. I personally like Linksys and DLink brands, but there are many others that will work well, too.

Security.
Don’t forget that you need to have at least some security on that home network.  At a bare minimum, you need a firewall and some kind of antivirus.  If you’re connecting to broadband internet, either cable or DSL, most often the router they give you from the service you use has a firewall on it.  If you’re using wifi, the wifi router almost certainly has a firewall on it.  Use them!  Most importantly, actually set them up and change the default password to something else that you’ll remember but that strangers won’t guess.  If you’re not sure if you have a firewall on your network equipment, then at least use the built-in Windows firewall, but use something!
If you don’t want to spend big money on either McAfee or Norton for antivirus, good news!  You don’t have to spend anything!  Yes, that’s right, you can download AVGFree and run it for nothing at all.  So, now, what excuse do you have to not be running some kind of antivirus again?
And, please, for your own sake, use passwords.  Use hard to guess passwords, not your kids names or your birthday or even your license plate number.  In fact, try not to use dictionary words at all, or, if you do, substitute other characters for letters, like $ for S or @ for A, to make it more difficult to guess.  Also, use numbers with the letters, for the same reason.

Networked Storage.
Just having storage isn’t enough, really.  On a home network now, you may have a laptop, or two, a desktop, a DVR or any number of different networked devices that share data.  They all need to store it somewhere.  And, even if they store the data locally, they need to be backed up somewhere.  The answer is network based storage.  There are a lot of options out there, and Rick Vanover at TechRepublic has a good article on several.  I know one solution that’s popular with photographers is the Data Robotics Drobo series of devices.  I don’t have any direct experience with these, so I have no opinion on them specifically, but these days, decent network attached storage is so cheap, it would be foolish to ignore that as an option.

Virtual Server Environment.
Now, obviously, this isn’t for everyone.  Back in the day, I used to run a small, two server Novell network in my house just to keep everything fresh in my mind.  Novell isn’t always the most popular networking environment, even for hard-core network geeks like me, so I always wanted to make sure I knew how to do some of the more “interesting” and challenging things in that environment and ran a test network at home for that reason.
Now, you can do all that through virtualization.  In fact, that may be the newest buzzword that’s already worn thin on me!  But, buzzword or not, setting up a virtual test network is something that’s been talked to death in the industry, but I’ve only seen one article recently on setting up a home virtual test network.  You can read more about it in an article by Brad Bird over at TechRepublic, but, again, for those of us who work in a lot of different environments, it’s not a bad idea to make a series of virtual machines to experiment on.  There are still some hardware costs involved, of course, but there is the advantage of being able to roll back to an earlier state if something gets too screwed up.  Try that on your old-fashioned home network!

Even Fancier Stuff!
Of course, there’s almost no limit to what you can do on a home network these days.  Many inexpensive printers come with network interfaces built in, some even have wifi networking built in.  Of course, I’ve mentioned things like Windows Home Server and Linux servers here before, too.  It is, after all, what I do.  Though, with the low prices on network attached storage, I’m not sure I’d recommend that option for the average user.
And, this post hasn’t even touched on integrating any audio visual equipment into your network, or a home security system, or some of the fancier bells and whistles that are out there.  The sky, literally, is the limit.

So, the thing is, everyone will have a different idea of what the “ultimate” home network is, but these are some things to consider, and a few you don’t want to forget.

Free Website Malware Scan

Filed under: Fun Work,Geek Work,The Dark Side — Posted by the Network Geek during the Hour of the Tiger which is terribly early in the morning or 5:00 am for you boring, normal people.
The moon is a Full Moon

This is only of interest to people who have webservers, but it’s worth writing about.

According to TechRepublic, QualsysGuard Malware Detection is letting you scan your webservers for free.
You have to be able to verify the domain with an e-mail address, so it really is for serious folks who actually have a webserver and verifiable e-mail, but it is free.  No word on how long it will be free, but, for the moment, it is, so go get it!

Home Servers

The moon is a Full Moon

What?  Doesn’t every one run servers at home?

Okay, so maybe not everyone does, but some of us hard-core geeks do.  And, some of those hard-core geeks are Lifehackers, too.  Thanks to that group of obsessed efficiency geeks, I can bring you a link to the Lifehacker Best Home Server software packages.  I can’t say that I’ve really worked with any of these, so I can’t chime in on which is best, but certainly the Lifehackers have done their research and left their comments.  If you’ve been thinking about setting up server for the family, this would be a good place to start.

And, if you want to add a DIY firewall, try hitting this article on TechRepublic about setting up a free pfSense firewall.  It’s Linux based, but I can’t vouch for it.  The author seemed to think a lot of it, though, so I’d be interested in what anyone thinks of it.  If you try it, give me a shout and we can talk about doing a guest post/review.

Semi-Random Network Resource Roundup

Filed under: Fun Work,GUI Center,Linux,MicroSoft — Posted by the Network Geek during the Hour of the Tiger which is terribly early in the morning or 5:57 am for you boring, normal people.
The moon is a Full Moon

Okay, maybe it’s more than a little random…

Here’s the thing, see, I spend a lot of time doing all kinds of weird stuff at the office.  I mean, I almost never have the same kind of day twice.  Really, the most consistent thing I do is go to lunch at more or less the same time every day.  Seriously.
But, along the way, I end up with some strange things in my browser.  All work related, of course, but, still an odd collection.  Here are a few things I found hanging around this week:

First, an article from TechRepublic about monitoring your network with a utility built into most, if not all, Linux distros called “ntop”.  Basically, it runs in the command shell and shows you were the network traffic your Linux machine can see is going.  Obviously, this is most useful if you use Linux for a firewall or gateway machine, since that would let you monitor pretty much all internet traffic.  Also?  Once you start it on that machine, you can get to it remotely via a browser to check the stats.  All for free.  Pretty cool.

Next, there’s another article on TechRepublic about resolving all those mysterious IP addresses into a physical location.  So, when you see that “special someone” trying to crack your home router, you can trace back to pretty close to where ever they are.  And, yes, for those of you who were readers back when I went through my divorce, that’s how I found out my ex-wife and her latest victim were following my blog.

But, if that wasn’t enough, here’s a third article from TechRepublic about a peer network monitoring tool that looks good.  One thing I liked about this was that it didn’t seem to need much special to run it, but it still had what looked like good notification tools.  If anyone has any opinions on it, or any of the other tools I’ve listed, please, feel free to add them into the comments.

And, last, but certainly not least, is a page of free web development tools from Microsoft.  Honestly, I have no idea how good these things are, but, hey, they’re free and they come from Microsoft, so, I figure they’re worth downloading.  I’ll probably never use them myself, but there’s no reason I shouldn’t share them with my readers.

So, yeah, these are all things that have been flying around in my browser at work for the past week or so.  Sometimes it’s great to be a generalist, because I never know what challenge I’ll be asked to meet next, but sometimes, it’s just exhausting!

Anyway, happy Wednesday and enjoy the links!

Linux Home Theater PC

The moon is a Full Moon

No, I haven’t done it. Yet.

But, when I do, I probably won’t end up using MythTV, like I thought I would. Rather, I think I’ll be using BoxxeeBox. Where MythTV is geared toward making a DVR, like Tivo, BoxxeeBox is more geared toward making home theater/multimedia machine, which is really what I want.

So, yeah, there are options.  Check this one out if you’re thinking about building a home theater machine.  It’s worth considering.

(And, yes, I’m trying to clean out old posts that have been lingering as drafts again.  New Year and all.)

41st Birthday of the Mouse

Filed under: Deep Thoughts,Fun,Fun Work,Geek Work,Life, the Universe, and Everything,News and Current Events,Ooo, shiny... — Posted by the Network Geek during the Hour of the Hare which is terribly early in the morning or 6:03 am for you boring, normal people.
The moon is a Full Moon

It’s not quite the “birthday” of the mouse, but…

Today is the 41st anniversary of the first time a mouse made its commercial debut, though the patent was actually granted just a few weeks earlier on November 17th. That’s right, the mouse, that marvel of modern technology that most of us use daily is just a little older than I am. Invented by Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, CA, the original mouse was little more than a square, wooden box, but the little device would change the world. Engelbart showed how the mouse could let a user jump from text on one part of the screen randomly to another section without having to scroll through the text inbetween. Doesn’t sound too revolutionary to us today, does it? But, think about how you navigated to this page to read this little blurb, then try to imagine doing it without a mouse.  Or, imagine trying to use Photoshop or any other graphic design program for that matter without the point-click-and-drag of a computer mouse.  Yeah, pretty much everything cool you can do on a computer these days involves a mouse or similar pointer.  Now, of course, to me, that’s the real genius of an invention like the mouse; it seems so obvious that we wonder why we didn’t think of it sooner!

So, happy demo day, little guy. Thanks for giving me a job and us a way to waste time at work.

Secure Shell on your Phone

Filed under: Adventures with iPods,Apple,Fun Work,Geek Work,Linux,News and Current Events,On The Road — Posted by the Network Geek during the Hour of the Pig which is late at night or 11:07 pm for you boring, normal people.
The moon is a Full Moon

I’ve been doing a lot more on my phone lately.

I’m not really big into the latest and greatest phone technology.  I don’t go out and grab the latest phone just because it’s come out and has new bells and whistles.  No, really!  But, I have to admit, my new iPhone has pretty much taken over a significant portion of my technological life.  And, I’m pretty much okay with that, because I love it.  One of these days, Real Soon Now, I’m going to write up a review of the VNC software I use on it to manage my servers remotely.  But, until then, I’m going to give you a quick high-light of something absolutely miraculous: secure shell sessions for your phone.

Yeah, now, notice that I didn’t write “for your iPhone”, but, rather, “for your phone”.  There are actually secure shell clients for all three of the big smartphone players; Blackberry, iPhone and Palm.
Now, for those of you not sure what I’m talking about, that’s okay, it’s a geek thing.  Secure shell is a protocol that hardcore, professional geeks like me use to securely access remote systems.  In a nutshell, it’s like Telnet, another hardcore geek tool, but it doesn’t pass information like usernames or passwords in “clear text“, which makes it more secure.  And, that’s the reason guys like me use it.  It lets us securely access servers remotely over networks in ways that don’t endanger our networks or users.  It used to be really only for Unix and Linux, but there are secure shell clients for just about everything now.  Frankly, more professional geeks should be using it for a lot of reasons, but many don’t.

Regardless, I think we’ve reached the pinnacle of technology when I can get a secure shell client for every major smartphone out there.  What that means is I can securely access virtually any kind of server from my phone, where there is a speedy enough data link.  Think about that for a second.  From my PHONE, I can securely access servers, wherever I may happen to have the freakish whim to do so and can get a decent cell signal.
I remember back in the days when you had to have an actual dial-up MODEM to get into servers remotely.  There was no method, secure or otherwise, to get into a server from home or anywhere else.  Now, I can do it, securely, from my PHONE!  How crazy is that?  Seriously!
So, if you want to be able to do that, too, here are links to three reviews of SSH software for the various smartphones. They should all have links to where you can actually download the software, if you want it.
SSH for Blackberry
SSH for iPhone
SSH for PalmOS

Also?  There are lots of applications for managing Windows servers, especially for the iPhone.  Check out Managing Servers and other systems from the iPhone.  It’s why I couldn’t hardly wait for the prices to come down to reasonable levels and why I babble about how there’s an app for everything on this iPhone. Really, it’s made so many things so much easier for me, I cannot begin to tell you.
But, I may just try.

No Free Lunch

The moon is a Full Moon

Ever wonder what I did before my blog devolved into what it is today?

Well, I uses write Perl code for fun. Yeah, that’s right, I used to code for fun. I mostly started with super geeky constructed language scripts and then moved on to other stuff. But, you know, I used to let people use them for free, just because it was fun and people seemed to really enjoy the scripts. Hey, there are a lot of geeky people out there! Anyway, it didn’t take long for these scripts, which used to reside at the Fantasist.net conlang page, to become very popular. It took even less time for them to become problematic for me and my series of webhosts. Well, they’ve finally become so much of a problem that I had to take them down this week.

Honestly, I can’t tell you how sad and angry and frustrated that makes me. I really wish I could keep offering them up, but people have abused them for too long and now they’ve caused me more trouble than they’re worth to me, so they’re gone for the forseesble future.

TwoAddictionsForThePriceOfOne

Originally uploaded by Network Geek

I bought an iPhone on Saturday.

Well, as I’m sure is no surprise to my regular readers, especially those who follow me on Twitter, I finally gave in Saturday and got myself an “upgrade” to the iPhone GS. My data plan won’t kick in until September 17th, when I’ll also have unlimited text messaging and slightly fewer actual voice minutes. The overall effect is to raise my monthly bill just $5, while ultimately giving me more services and, yes, more fun.

I actually debated for quite some time about getting the iPhone, a Blackberry or the new Palm Pre. I have to admit, I was really excited about the Pre, because I’ve been a Palm fan since way back. In fact, at one point I was such a fan of Palm, as a company and a platform, that I registered HavePalmWillTravel.com. Well, that and there was a little joke about an e-mail address and a technological “gun-for-hire”. In any case, I decided against the Pre for a number of reasons, not the least of which is they weren’t on AT&T, where virtually all my contacts are. Also, they’re still unproven in the current market and there still aren’t as many applications for the Pre as both of the other two smartphone choices.
One of the things I really needed my smartphone to be able to do is remotely manage my server or servers. Now, I know that there are remote communication and control apps for the Blackberry, but, frankly, the touchscreen Blackberry just isn’t all that great and the other Blackberry devices have rather, well, puny screens. If I’m going to manage a Windows server, I’m going to need a big screen to see everything and make it all work. So far, no Blackberry device has a screen that I think is big enough to make that happen. So, that left me with the iPhone.

So, within just a day or so of getting my new toy, I had found the free Mocha VNC Lite. Now, I suppose I should have taken a screen shot of that, but, frankly, I didn’t want the hassle of finding a clean, safe shot of my Windows server at the office, so I decided to go with a different shot. Again, since my data plan hasn’t kicked in yet, I haven’t tried the VNC client via the 3G network, but it works disturbingly well over my wifi network at home. When I do get that chance, though, I may do a full review of all the remote clients that I’m willing to actually load on my iPhone to try out.
But, there are other apps that I think I may just get addicted to and this shot shows one of them. Yes, that’s a WordPress client on the iPhone from the same people who bought you the WordPress software itself. If you look closely, you can see that I’ve already set it up for this blog and another one that’s in the works. So, yes, when the data plan is active, you can expect to see both posts and, possibly, even posts with pictures shot on the iPhone. Who knows, maybe even video!

So, as the marketing gurus say, watch this space for further developments!
