Lock and unlock your computer with a USB drive.

If you prevent access to your computer with just a password, you are missing out on an alternate (and more secure) way to lock down your computer.

Predator, a free Windows program, turns your USB drive into a key that locks your computer when it's removed. To unlock your computer, you'll have to plug the USB drive back in. (Talk about having secret-agent-style security.)
Anyone who attempts to access your computer without the USB flash drive will be hit with an epic "Access Denied" message. To get started, follow this guide:
Step 1: Download and install Predator.
Step 2: Once Predator launches, plug in your USB flash drive. None of the contents of the drive will be deleted or altered in any way, so feel free to use your primary thumbdrive.
When you insert the drive, a dialog box will appear asking you to create a password. Click OK to continue.
Step 3: In the Preferences window,

Hosting Websites from your own computer

With Wamp

WampDeveloper is configured, by default, to pick up and answer all requests it receives (access to websites is not blocked)... But these requests have to get to WampDeveloper first.
If a website works locally but not remotely, the requests are not reaching WampDeveloper's Apache Service.

When a request comes in to the system that WampDeveloper is running on, WampDeveloper will check the "host header" (specifies the domain name) of the HTTP request and cross-reference it to the websites it contains (via the website's domain name and aliases data). When there is a match, WampDeveloper returns that specific website. When there is no match, WampDeveloper returns the "DefaultWebsite"...
So as long as the request reaches the server, or more specifically the WampDeveloper's running Apache Service, something (a website) will be returned.

Local Development

To develop and test a website locally you can do so using a non-registered (made up, fake) domain name.
Simply add a website using a Primary Domain Name such as: www.example.com and you will be able to access URL http://www.example.com/ in your browser. No other steps

Step One: Installation

New Install of Fedora

Choose which packages you want to install with the “Customize Now” switch. Choose it and then under the Servers tab, you can select “Web Server”. Go ahead with the installation until

Hack the password of windows xp.

1. Place your Windows XP CD in your cd-rom and start your computer (it’s assumed here that your XP CD is bootable – as it should be - and that you have your bios set to boot from CD)
2. Keep your eye on the screen messages for booting to your cd Typically, it will be “Press any key to boot from cd”
3. Once you get in, the first screen will indicate that Setup is inspecting your system and loading files.

4. When you get to the Welcome to Setup screen, press ENTER to Setup Windows now
5. The Licensing Agreement comes next - Press F8 to accept it.
6. The next screen is the Setup screen which gives you the option to do a Repair.

It should read something like “If one of the following Windows XP installations is damaged, Setup can try to repair it”
Use the up and down arrow keys to select your XP installation (if you only have one, it should already be selected) and press R to begin the Repair process.
7. Let the Repair run. Setup will now check your disks and then start copying files which can take several minutes.

How To Detect Phishing Attacks

1. Use a Custom DNS Service

You need a DNS resolution service so that you can access all the sites that you go to. Your computer doesn’t automatically know

IT-Learning: You Should Make Your Own Server

1. You Control Your Data
If you’re an avid user of the Web, you probably have all kinds of information spread out over multiple servers and websites. For example, chances are you use Dropbox. Although it’s extremely convenient, your files are ultimately stored on their servers, so that means they control your data. You can protect yourself through different methods of encryption, but the storage location stays the same. You can change that by setting up your own server to hold your data. That way, what’s yours stays yours, and it will stay that way as long as you run your own server. With good security, other prying eyes won’t be able to see what you’re storing on your own server, so privacy is included.

2. You Build Your Own Services

With your own server, you can do whatever you want with it. Run an email server to handle all your email (although saying goodbye to Gmail

1. DNS

The Domain Name System, which is responsible for determining the corresponding IP address when you type a site name like www.smallbusinesscomputing.com into a browser. DNS service is typically provided by an ISP (though many small businesses also run DNS internally to locate resources on corporate networks), and it can often be a source of poor browsing performance and intermittent site connectivity problems.

Free or inexpensive alternative DNS providers like ClearCloud, Google Public DNS or OpenDNS can provide speedier and more reliable website access, protection against malware and phishing pages, as well as enhanced features like Web content filtering and activity logging.

2. Dual-Band Wi-Fi

This refers to 802.11n-compatible Wi-Fi hardware that can utilize two distinct frequencies -- the standard 2.4 GHz frequency used by 802.11b/g, and/or the 5 GHz frequency used by 802.11a. Although 5 GHz Wi-Fi devices generally have a shorter range than their 2.4 GHz counterparts, using the 5 GH z frequency can still be beneficial because it provides higher capacity -- i.e. more access points in a given amount of space-- and is far less susceptible to interference from outside sources, including from other wireless networks.

SSH

This can be used to securely remotely login to another device which has remote login enabled. It is commonly used to login to jailbroken iPhones and send files. It is also used to repair computers without a display attached or to make sure they are still working. SSH can also be used to tunnel web traffic.

If you’re on OS X, you must make sure that remote login is turned on in the computer you want to remotely login to. You can do this by going to the Sharing pane in System Preferences, then ticking the “Remote Login” checkbox. Note down the bit in quotes after, “To log in to this computer remotely…”

That’s what you have to type into the terminal to log in to that account on that computer. To login using SSH, simply type:

ssh user@host

Where host is the IP. Then verify that

Broadband

This refers to high-speed data transmission in which a single cable can carry a large amount of data at once. The most common types of Internet broadband connections are cable modems (which use the same connection as cable TV) and DSL modems (which use your existing phone line). Because of its multiple channel capacity, broadband has started to replace baseband, the single-channel technology originally used in most computer networks. So now when you see companies like AT&T and SBC pushing those fancy "broadband" ads in your face, you'll at least know what they are talking about.

Reformat Your FAT32 Drive To NTFS

You may not know it, but choosing the right filesystem for your drives is actually pretty important. Although the main idea of all filesystems is the same, there are many advantages and disadvantages with each one.

While there are lots of filesystems out there, we’ll be looking at the most popular two, FAT32 and NTFS.

About the Filesystems

FAT32

FAT32 used to be the default filesystem for many of the older, non-NT versions of Windows, such as Windows 95, 98, and ME. The original FAT specification was introduced in 1980, while the compatible FAT32 specification was introduced in 1996. More recently, an incompatible exFAT specification has been introduced that is meant to replace the use of the old FAT.

NTFS

Meanwhile, NTFS (or “New Technology File System”) was introduced in 1993, but has received many improvements over the years along with newer operating systems. While it is not used for removable storage (where FAT-type filesystems are prevalent), it is the best choice for

Automate Your Telnet Job

There are basically two parts to this task. You need to establish the sequence of commands that you want to go through during the typical telnet session.

Here’s what I want to do. I have 5 devices throughout the network that can be remotely rebooted via telnet by issuing 4 simple commands. I have to first telnet to it using the IP address and a specific port. Next, a menu appears, and I have to first press enter.

After I hit enter during this telnet session, the next
