Clear Your DNS Resolver Cache Just To Be Safe

leave a comment »

So, you think going incognito or deleting your browsing history will keep your boss from finding inappropriate sites?  It does to some extent, but if someone really wanted to catch you in the act—whatever act that may be—then they wouldn’t have too much of a hard time.

We all know that your computer has to talk to a DNS service provider to translate the URL you type to an IP it can use.  Every time your computer has to resolve an address issue it’s cached in your systems DNS cache—basically, it’s your browsing history.  This browsing history isn’t restricted to your browser, it’s anytime your computer has to locate another server on the internet.

To find out what’s in your DNS cache is to bring up the command prompt in Windows and type the command:

ipconfig /displaydns

Now, the first thing you’ll notice is that a whole lot of information will appear, to the point that all of it can’t fit in the command prompt.  What you can do is take the output of the command and send it to a text file somewhere on your machine.

ipconfig /displaydns > c:\desired location

Now, when you open that file you’ll see information about the websites you’ve visited directly or indirectly.

You’ll see blocks like the one below; you might have multiple entries under each heading.

mail.google.com
—————————————-
Record Name . . . . . : mail.google.com
Record Type . . . . . : 5
Time To Live  . . . . : 151
Data Length . . . . . : 8
Section . . . . . . . : Answer
CNAME Record  . . . . : googlemail.l.google.com

Finally, how do you get rid of this, so that the cops knocking on your door have a harder time finding your browsing history—they’ll eventually find it, you’re just delaying them.  Just type the command below and your DNS cache will be cleared.

ipconfig /flushdns

Once you’ve typed that you’ll get a nice little message saying it was successful.

Windows IP Configuration

Successfully flushed the DNS Resolver Cache.

That’s it.  Your DNS cache is clean of whatever inappropriate sites you visited.

Bridge Connection Between PC and PlayStation 3

with 18 comments

If you’re like me, a gamer, you prefer a guided network connection for your PS3 (everything else is inferior) and PC.  However, not everyone’s console is conveniently located next to a router or modem.  In my case the router is upstairs and a 50 foot Ethernet cable running to the main computer. I could buy a switch and use it for what it was made, but that would cost money.  I could also buy another 50 foot cable, but that would mean I’d have to buy one, drill another hole and crawl through areas of my house I didn’t know exist.  Luckily my PC is very close to my PS3 meaning I can share my connection.  Your PC doesn’t have to be close to your PS3, but in this case I am assuming your PC is closer to your PS3 than your router, else you wouldn’t have ended here.

Windows Settings:

Make sure your computer has two Ethernet ports. Your motherboard may have two, if not you can buy a cheap Ethernet card online or in a store.

Ethernet Ports

After making sure all the hardware is present you need to make the connection on your PC a bridge connection. Open Network and Sharing Center, on the left click Change adapter settings. There you should see both adapters.

NetworkSharingCenter

Select both adapters by highlighting them. Once both are selected right click and choose Bridge Connection.

bridgeConnection

Once you’ve selected Bridge Connection Windows will do its thing and set up everything. It takes a few seconds Windows to up the bridge and for your computer to re-establish a connection.

ConnectionBridged

Now hook up your PS3 to your PC and Windows will do its thing again. However, you have to change some settings on the PS3.

PlayStation 3 Settings:

*Sorry that I don’t have any PS3 screens at the moment. I may add some later on.

Once your PS3 is ON go to Network Settings, there choose Internet Connection Settings. Choose Custom >Wired Connection > Manual Settings. For Speed and Duplex leave it on Automatic unless you know the speed, the same goes for IP Address. Under DHCP host name choose Do Not Set. Leave DNS and MTU Automatic. For Proxy Server choose Do Not Use.  Enable UPnP. Test you’re set up and it should come out just dandy.

*Note: This works between PCs as well. All you do is connect the two PCs together and let the OS (assuming it’s Windows) take care of the rest. If it doesn’t work and you’re running 7 or Vista use the automated problem detection to fix the problem.

Enjoy your bitchin’ speed.

Windows 7 RTM

leave a comment »

Windows 7 is here, well for people lucky enough to be part of a group that receives the RTM before October 22nd –people like me. It may seem like yesterday when Microsoft introduced Windows Vista (three years actually), so it makes you wonder –is 7 worth upgrading to?  The short answer is yes.

The post will simply point out the strong points of 7– nothing more, nothing less

The install is much quicker than the beta or RC.  I thought about using a flash drive but I ended up not being able to find one, so I used a DVD .  I formatted my drives, designated a primary drive and clicked install.  From there it was just click, click, done.  It took about 20-25 minutes to install windows, with another 30 minutes to install all the drivers for my hardware.

Compatibility wise Windows 7 is right where it belongs -compatible. Believe it or not, the fact that 7 is compatible with current hardware is all thanks to Vista.  If you have drivers that work in Vista they’ll most likely work in 7. Even XP drivers work, thanks to the compatibility feature –which is also present in Vista.  I was caught off guard when I wanted to install Intel x58 drivers; Vista has to install about 30 drivers, 7 on the other hand only needs two.

Microsoft tweaked the UI scheduler a lot in order to make 7 more responsive.  Vista implements a modified XP UI scheduler, which works fine –in XP, but Vista’s UI upgrades overburden it.  Windows 7 has moved away from the old scheduler to a model employing division of labor.  Instead of having one scheduler juggling all the UI I/O there are several which are prioritized in the OS.

There is not much to add that hasn’t been said. 7 definitely is on the right track, the only problem I see are the “I am a Mac” commercials –I don’t think they’ll work anymore.  Bummer.

Yes I know this is a very short post considering I am posting about Windows 7. However, chances are you’ve hit Engadget or Gizmodo before arriving here and you’ve read their reviews.

Windows 7 RC vs Mac OS X 10.5.7 -Boot Up

with one comment

I don’t know about you, but I’ve always wanted a side by side showing of Windows 7 and Mac OS X. I didn’t go to YouTube and pick a random video, because I don’t know how the video was done and the hardware that was used.

As you can see below the specs of the Mac are higher end.  Which again, isn’t ideal, because you’d want  identical hardware to compare different Operating Systems.

MacBook:

Intel Core 2 Duo

Processor Speed:    2.4 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    3 MB
Memory:    2 GB
Bus Speed:    800 MHz

HP dv2315:

AMD Turion TL-56

Processor Speed:    1.8 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    1024 KB
Memory:    2 GB
AMD System Bus Speed:   1600 MHz

Boot up video:

October 22nd can’t arrive soon enough.

Blue Screen of Death Counter

leave a comment »

FunnyBSOD

Ever wonder what the number of daily BSOD mentions on twitter is?  I really want to say there’s an app for that. But there isn’t.  However, there is a twitter account called @WindowsDeath that keeps track of “BSOD” or “Blue Screen” mentions on twitter.  Pretty funny if you ask me.  It’s entertaining to read, each person is provided with their personalized BSOD screen, even I got one.

When you go to your personal BSOD and press any key to continue, just like a real-fake BSOD, you’re taken to the home page, which explains what Windows Death is, there’s even a total deaths counter and deaths per day.

Messages from the bot it include the total death counter and a witty response to whatever you tweeted. You’d think an Apple fanboy was tweeting to you. Yes, I just did.
