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.

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 -Exclusive Device Control

leave a comment »

When I installed Windows 7 RC, and RTM, I kept experiencing an annoying problem. Whenever I started a video game  my volume would drop to almost zero.  For the longest time I couldn’t figure out why.  After some snooping around I found the problem.  It’s a simple check box that tells the system if applications should be allowed to have exclusive control of the Sound Playback Device or not.

If you’re having this problem follow the steps below to make it work properly.

Open Playback devices. Right click the speaker in the lower right and chose Playback devices.

Playback Devices

Next select your default sound device, in my case Digital Audio (S/PDIF), and click properties.

Sound Devices

In the properties window go the Advanced tab. Under Exclusive Mode un-check “Allow applications to take exclusive control of this device.”

Exclusive Control

Click OK and you’re done. Your sound should work properly now when you start a game, movie, or whatever it is that has been dropping/increasing your volume.
