Open a gnome-terminal window and type
su
(provide the root password)

Code:

cd /usr/share/polkit-1/actions && cp -p org.freedesktop.udisks.policy org.freedesktop.udisks.policy_original

(it is always advisable to save the original copy of any configuration file before modifying it).

Next, still as a superuser, open in a text editor following file

/usr/share/polkit-1/actions/org.freedesktop.udisks.policy


and find the block of text containing the line:

    <description>Mount a system-internal device</description>

On Fedora 14, this is the third block from the top (the first is the header, the second is the «Mount a device» block). A few lines below in the same block you will find the line:

      <allow_active>auth_admin_keep</allow_active>

Modify it as follows:

      <allow_active>yes</allow_active>

Save the changed file and exit the editor.

The change takes effect immediately: no need to log out or reboot.

Tracking the Location of An Email Sender

Sometimes it seems essential to track the location of the person who send you an email. To find if the email came from a genuine sender or not… To get some of the background details or the GEO details of the person.

In Gmail or any other email client, when a person send you an email, there is always more information at your disposal then actually that is on surface. To know more information, we need to dive into an email header. Along side the Reply button there is a dropdown option of Show Original. When you click this an original message with all details and email header is shown to you.

In this header text of email (CTRL + F) the text Received: from . It is of utmost importance to know the details of sender. In front of this field the public IP address or the smtp address of the sender is mentioned. The IP address is mentioned like [ xxx.xxx.xxx.xxx].


After you have this public IP address of sender, you can now actually do a Reverse IP lookup or a Reverse Email Lookup.

Below are some of the tools to do this lookup:

1. Visual Trace route Tool : This tool helps you do that and much more visually http://www.yougetsignal.com/tools/visual-tracert/. You just need to enter the IP address mentioned in square brackets. It will then show you each and every IP address and locations through which the Email has traversed on map.
2. Facebook : You can also track the sender by doing reverse email lookup in facebook. Just type in the email ID of sender in facebook search and if you are lucky you will find his/her profile page.
3. IP2Location : This is a webapp for tracking the info like Country, State, City, Latitude, Longitude and ISP
4. GEOBytes : Its also a Reverse IP lookup program that get many useful pieces of information from the IP location.

Apart from these ways you can also search for sender’s email address in google search. From there you may find person’s social profiles, websites and many other thing

super account in vista

Deep inside the bowels of Windows Vista, there’s a secret Administrator account, and it’s different from the normal administrator account you most likely have set up on your PC. This Administrator account is not part of the Administrator group.It’s a kind of superadministrator, akin to the root account in Unix, and by default it’s turned off and hidden. (In describing this article, i’ll always use the capital “A” for the secret Administrator account, and a lowercase “a” for a normal administrator account.)

In versions of Windows before Windows Vista, the Administrator account wasn’t hidden, and many people used it as their main or only account. This Administrator account had full rights over the computer.

In Windows Vista, Microsoft changed that. In Vista, the Administrator account is not subject to UAC, but normal administrator accounts are. So the Administrator can make any changes to the system and will see no UAC prompts.

Turning on the Administrator account is straightforward. First, open command prompt by typing cmd into the run box on the Start menu, or by right-clicking the command prompt icon that appears at the top of the Start menu, then selecting Run as administrator.

Then enter this command and press Enter:

Net user administrator /active:yes

From now on, the Administrator account will appear as an option on the Welcome screen, along with any user accounts you may have set up. Use it like any other account. Be aware that it won’t have a password yet, so it’s a good idea to set a password for it.

If you want to disable the account and hide it, enter this command at an elevated command prompt and press Enter:

Net user administrator /active:no

Improve the speed & load time of firefox

• network.http.max-persistent-connections-per-server = 10

• network.http.pipelining = true

• network.http.pipelining.maxrequests = 200
