Checking the sites your computer is connecting to in Windows

Have you noticed a sudden drop of your Internet speed? A possible explaination is that some nasty program is doing things behind your back. Whether it is spyware, malware or adware you might have a serious case of unauthorized traffic on your hands.

But don’t worry, it’s quite easy to get a list of your connections in Windows. Such a list may turn quite helpful and may help you find some unknown applications are using your bandwidth for their dirty bidding.

Naturally this list will be generated through the Command Prompt. First, open the Command Prompt under Administrator Mode. To do that, open the Start menu, type cmd in the search box:

Right-click on cmd.exe and select Run as administrator:

The command prompt will open:

Enter the following command:

netstat -fab 5 > connections.txt

Now, before we press Enter, let’s take a moment to look what exactly are we doing here. First of all netstat is a command that generates a lot of useful information about your network status. Additionally there are several options we can add to our netstat command, some of which are:

 -f – for displaying the full DNS name for hosts on the other side of each connection. This makes the generated data a lot easier to comprehend.

-a – to put it simply this stands for “all”. As in “all connections and listening ports”.

 -b – to output the name of the application making the connection.

Alternatively to -f you can use -n to display only IP addresses.

Naturally, “5” stands for how often do we want this information to be gathered. Finally, “> connections.txt” means that we want to output this information to connections.txt (so called piping).

So now that we now what we are doing, we can freely hit Enter.

Wait for a couple of minutes and press Ctrl + C to stop netstat. Now you can open connections.txt (which in our case is located in C:\Windows\System32  because we ran netstat from there) and see the activity of every application for the moment you started netstat, until you turned it off.

Note: This information may not be complete as we set netstat to update once in five seconds.

Note: This trick works on Windows 7 and Windows Vista. If you are still using Windows XP you need at least SP2.

Generate a Realistic X-Rayed Hand in Illustrator CS5

X-rays are useful in the detection of diseases, broken bones, or radiotherapy. The most used method of X-rays is photographic plates. Photographic plates can generate images of human and animal internal structures. Today, we are going to develop an X-ray image of a hand with the help of Illustrator CS5. No, we don’t need photographic plates or film; we just need the Pen Tool and Inner and Outer Glow effects. Let’s begin!

We stand behind Server Intellect and their support team. They offer dedicated servers, and they are now offering cloud hosting!

STEP ONE:
Open a New Illustrator Document (File > New) with a size of 500px by 600px.

NOTE: This step requires basic Pen Tool expertise.
Find a real X-Rayed Hand image or a hand skeleton graphic; place it as a Template Layer in Illustrator, and in a New Layer with the Pen Tool (P) trace the skeleton hand outline. Make sure to close all the paths.
Here is a template image with the outline that I traced:

(Image zoomed out to 50%)

NOTE: Image and file are available for download at the end of this tutorial.

Delete the Template layer.

STEP TWO:
Select the entire outline (Mac: Command + A / PC: Control + A). At the COLOR palette (Window > Color) give it a light blue color value of (R= 128, G= 169, B= 189) with no stroke.
Then, go to Effect > Stylize > Inner Glow and enter the following settings:

Make sure to select white as the Mode color.

You should obtain the following effect:

STEP THREE:
At the LAYERS palette (Window > Layers) create a New Layer under the layer where you drew the outline of the hand and name it, “Background”.

Select the Rectangle Tool (M), click anywhere on the canvas area to open its dialog box, and enter a Width of 500px and a Height of 600px. At the GRADIENT palette (Window > Gradient) select a Radial gradient with the following color values:
First color box: (R= 0, G= 32, B= 43)
Second color box: (R= 0, G= 3, B= 21)

Lock the layer ().

STEP FOUR:
Go back to the layer with the hand, select all (Mac: Command + A / PC: Control + A), and press (Mac: Command + C / PC: Control + C) to copy.
Lock the layer.

Create a New Layer and name it, “Framework”. Press (Mac: Command + V / PC: Control + V) to paste the hand on this layer. Place it on top of our other hand, like so:

We used over 10 web hosting companies before we found Server Intellect. They offer dedicated servers, and they now offer cloud hosting!

With our Hand Copy selected press Shift + X to remove its fill color and effect. At the COLOR palette notice that now the stroke has the blue color we chose for its fill, change it to white.
Now, at the STROKE palette (Window > Stroke) change its stroke Weight to 3pt.

Next, go to Effect > Stylize > Outer Glow and apply the following settings:

There we have it, an X-Rayed Hand in Illustrator CS5:

Now that you know how to create an X-Ray effect, generate more X-Rayed objects. Have fun!

We moved our web sites to Server Intellect and have found them to be incredibly professional. Their setup is very easy and we were up and running in no time.

How to hide which sites you have visited in Windows

Most of the browsers support a Private Browsing mode which allows users to surf anonymously without storing any history of the session. Although this does help you remove some of your Internet tracks it still leaves some information that can be retrieved by someone who knows a thing or two about computers. The thing is that this Private Browsing mode doesn’t delete the DNS cache. This means that, if someone types ipconfig /displaydns in the Command Prompt, he can easily find out the websites you have visited. To take care of that, we will show you how to clear you DNS cache.

First we need to run the Command Prompt in Administrator mode. To do that, open the Start menu, type cmd in the search box:

Creating System Environment Variables in Windows 7

Every administrator who uses batch scripts is well aware of the built-in environment variables (WinDir, Path, ProgramFiles, etc.). Using them makes your batch scripts a lot more portable on other systems and is overall a rather good practice. For example instead of modifying a batch script for a different system in which the Windows directory is located in a different place you can simply use the WinDir environment variable. We use it like so: Read the rest of this entry »
