TWEAKING WINDOWS SENT TO MENU

How often do you copy songs from a CD? Or some photos from a CD?

What do you do? You select the required files and do a CTRL –C. Open the destination folder and do a CTRL-V. Here is something you can benefit time from. Customize your SEND TO MENU.

This sounds simple and you can do it in less than sixty seconds.
You can create your own BASKET.

First you’ll need access to hidden files. So change your view settings to make all hidden files visible.
Tools -> folder options -> view (tab) and select the show hidden files and folders.
go to parent drive:/documents and settings/(user name)/send to

Open up my computer and locate your most used folders.

Create a shortcut of the most used folders in SEND TO FOLDER.You can do this in a number of ways.

Right click -> send to desktop(create shortcut) and move the shortcut from the desktop to the SEND TO FOLDER.

Copy the most used folder and go to SEND TO FOLDER and right click -> paste shortcut.

Also remember to rename the shortcuts to send to videos or send to potos. We don’t need confusion when we use the same later.

Improve your dialup modem preformance

You can't assume that just because you connected at a speed like 48.3KBps that you will stay there. Today's modems automatically fall back to a lower speed if the line noise is too high to maintain a faster connection, but sometimes they fall back too soon or too far.

Here's how to do it:


Click Start the button.
Select Settings.
Click Control Panel.
Double-click on the Modems icon.
Select your modem.
Click the Properties button.
Click the Connections tab.
Click the Advanced button.
In the "Extra settings" field, type S36=7
Click OK to save your settings.


This will force your modem to try to stay connected at high speeds in two different ways before dropping back to an asynchronous mode with auto speed buffering.

How To Remove The Default Adminstrator Shares

By default Windows 2000, Windows XP and WinNT automatically setup hidden admin shares (admin$, c$ and d$), this registry key will disable these hidden shares.

System Key: [HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Services\ LanmanServer\ Parameters]
Value Name: AutoShareWks
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = disable shares, 1 = enable)

This registry key actually stops the recreation of the shares, therefore it may be necessary to delete the shares through the drive properties also or you can also remove the shares through the Computer Management Console.

1. In Control Panel, double-click Administrative Tools, and then double-click Computer Management.

2. Click to expand Shared Folders, and then click Shares.

3. In the Shared Folder column, right-click the share you want to delete, click Stop sharing, and then click OK.

Note : To remove the admin share for only the current session use the second method (Computer Management console), if you want a permanent removal, add the AutoShareWks registry.

How To Make XP Go Faster

Services You Can Disable

There are quite a few services you can disable from starting automatically.
This would be to speed up your boot time and free resources.
They are only suggestions so I suggestion you read the description of each one when you run Services
and that you turn them off one at a time.

Some possibilities are:
Alerter
Application Management
Clipbook
Fast UserSwitching
Human Interface Devices
Indexing Service
Messenger
Net Logon
NetMeeting
QOS RSVP
Remote Desktop Help Session Manager
Remote Registry
Routing & Remote Access
SSDP Discovery Service
Universal Plug and Play Device Host
Web Client

To clean this periodically go to:

Star / Run / Prefetch
Press Ctrl-A to highlight all the shorcuts
Delete them

--------------------------------------------------------------------------------

Not Displaying Logon, Logoff, Startup and Shutdown Status Messages

To turn these off:

Start Regedit
Go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionpoliciessystem
If it is not already there, create a DWORD value named DisableStatusMessages
Give it a value of 1

--------------------------------------------------------------------------------
Clearing the Page File on Shutdown

Click on the Start button
Go to the Control Panel
Administrative Tools
Local Security Policy
Local Policies
Click on Security Options
Right hand menu - right click on "Shutdown: Clear Virtual Memory Pagefile"
Select "Enable"
Reboot

For regedit users.....
If you want to clear the page file on each shutdown:

Start Regedit
Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementClearPageFileAtShutdown
Set the value to 1

--------------------------------------------------------------------------------

No GUI Boot

If you don't need to see the XP boot logo,

Run MSCONFIG
Click on the BOOT.INI tab
Check the box for /NOGUIBOOT

---------------------------------------------------------------------------------
Speeding the Startup of Some CD Burner Programs

If you use program other than the native WindowsXP CD Burner software,
you might be able to increase the speed that it loads.

Go to Control Panel / Administrative Tools / Services
Double-click on IMAPI CD-Burning COM Service
For the Startup Type, select Disabled
Click on the OK button and then close the Services window
If you dont You should notice

--------------------------------------------------------------------------------

Getting Rid of Unread Email Messages

To remove the Unread Email message by user's login names:

Start Regedit
For a single user: Go to HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionUnreadMail
For all users: Go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUnreadMail
Create a DWORD key called MessageExpiryDays
Give it a value of 0

------------------------------------------------------------------------------

Decreasing Boot Time

Microsoft has made available a program to analyze and decrease the time it takes to boot to WindowsXP
The program is called BootVis

Uncompress the file.
Run BOOTVIS.EXE
For a starting point, run Trace / Next Boot + Driver Delays
This will reboot your computer and provide a benchmark
After the reboot, BootVis will take a minute or two to show graphs of your system startup.
Note how much time it takes for your system to load (click on the red vertical line)
Then run Trace / Optimize System
Re-Run the Next Boot + Drive Delays
Note how much the time has decreased
Mine went from approximately 33 to 25 seconds.

--------------------------------------------------------------------------------
Increasing Graphics Performance

By default, WindowsXP turns on a lot of shadows, fades, slides etc to menu items.
Most simply slow down their display.

To turn these off selectively:

Right click on the My Computer icon
Select Properties
Click on the Advanced tab
Under Performance, click on the Settings button
To turn them all of, select Adjust for best performance
My preference is to leave them all off except for Show shadows under mouse pointer and Show window contents while dragging

---------------------------------------------------------------------------

Increasing System Performance

If you have 512 megs or more of memory, you can increase system performance
by having the core system kept in memory.

Start Regedit
Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementDisablePagingExecutive
Set the value to be 1
Reboot the computer

---------------------------------------------------------------------------

Increasing File System Caching

To increase the amount of memory Windows will locked for I/O operations:

Start Regedit
Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management
Edit the key IoPageLockLimit

-----------------------------------------------------------------------------

Resolving Inability to Add or Remove Programs

If a particular user cannot add or remove programs, there might be a simple registry edit neeed.

Go to HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesUninstall
Change the DWORD NoAddRemovePrograms to 0 disable it

4096 - 32megs of memory or less
8192 - 32+ megs of memory
16384 - 64+ megs of memory
32768 - 128+ megs of memory
65536 - 256+ megs of memory

How to Install and run Windows CE on your USB Stick

Portable Windows CE is a 'launcher' for the Windows CE device emulator that can run an emulator-based image from a USB keychain.

Download the Windows CE 5.0 Device Emulator.
Code:
http://www.Mcft.com/downloads/details.aspx?FamilyID=A120E012-CA31-4BE9-A3BF-B9BF4F64CE72&displaylang=en

Change "Mcft" in link to what it is supposed to be icon_wink.gif

Extract the emulator to a folder on your hard drive by running "setup /a". The installer will prompt you to specify a directory to extract to . For example: D:\PortableCE

Download this launcher script:
Code:
http://www.furrygoat.com/Software/launchce.cmd.txt


Copy the following launcher script to the directory you extracted the setup to. You'll need to rename the file from launchce.cmd.txt to launchce.cmd
Once you have that set up, just copy the entire D:\PortableCE folder over to your USB keychain.

To launch the emulator, just plug in your USB keychain, navigate to the PortableCE folder, and run launchce.cmd. You should (hopefully) have the emulator fire up.

HOW TO GET ANY WINDOWS PASSWORD

ok..... here are the full details.....

this works whether its windows 2000 or windows xp or windows xp SP1 or SP2 or windows server 2003....

this works even if syskey encryption is employed...

if it is FAT filesystem...

just copy the sam file like stated in the first post to an empty floppy disk and take it home. I'll tell u what to do with it later... DON'T DELETE THE ORIGINAL SAM FILE. just remove its attributes. the sam file is a file called SAM with no extension. YOU MUST ALSO GET.... a file called SYSTEM which is in the same folder as SAM. both files have no extensions...

if it is NTFS....

u have to download a program called NTFSPro.... it allows u to read from ntfs drives... the demo version allows read only. the full version is read-write.... you use the program to create an unbootable disk (so u will still need another bootable disk and an empty disk) that has the required files to access NTFS.

use the boot disk to get into dos, then use the disks created with ntfspro to be able to access the filesystem, then copy the SAM and SYSTEM files to another empty disk to take home....

AT HOME: u have to get a program called SAMInside. it doesn't matter if it is demo version. SAMInside will open the SAM file and extract all the user account information and their passwords, including administrator. SAMInside will ask for the SYSTEM file too if the computer you took the SAM file from has syskey enabled. syskey encrypts the SAM file. SAMInside uses SYSTEM file to decrypt the SAM file. After SAMInside finishes, u still see user accounts and hashes beside them. the hashes are the encoded passwords. Use SAMInside to export the accounts and their hashes as a pwdump file into another program, called LophtCrack. it is currently in version 5, it is named LC5. the previous version, LC4 is just as good. u need the full or cracked version of the program. LC5 uses a brute force method by trying all possible combinations of letters numbers, and unprintable characters to find the correct password from the hashes in the pwdump file imported into it from SAMInside. This process of trying all passwords might take 5 minutes if the password is easy, up to a year if the password is long and hard (really really hard). LC5 howver, unlike LC4, is almost 100 times faster. both can be configured to try dictionary and common words before using all possible combinations of everything. Once the correct password is found, it will display the passwords in clear beside each account, including administrator.

I use this method so many times. I've compromised the whole school computer infrastructure. LC4 usually took between 1 second and 10 minutes to find the passwords because they were common words found in any english dictionary. I haven't used LC5 yet.

If there is anything unclear, anything I overlooked, plz tell me so that I can turn this into a very easy to follow tutorial to help anybody crack any windowz pass.

Programs needed: SAMInside (doesn't matter which version or if demo)
LC4 or LC5 (lophtcrack)( must be full version)
NTFSPro (doesn't matter if demo)
any bootdisk maker

Cracked or full version software can be found on any warez site. If u don"t know what that is or where to get the programs, post a message and I'll tell u or give them to u.

P.S: I might not keep track of this forum, because I'm going to create a new topic and post tutorial there. if u want to post, plz post there.

How to Bypass BIOS Passwords

BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS

DISCLAIMER
This article is intended for IT Professionals and systems administrators with experience servicing computer hardware. It is not intended for home users, hackers, or computer thieves attempting to crack the password on a stolen PC. Please do not attempt any of these procedures if you are unfamiliar with computer hardware, and please use this information responsibly. LabMice.net is not responsible for the use or misuse of this material, including loss of data, damage to hardware, or personal injury.


Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:

Using a manufacturers backdoor password to access the BIOS

Use password cracking software

Reset the CMOS using the jumpers or solder beads.

Removing the CMOS battery for at least 10 minutes

Overloading the keyboard buffer

Using a professional service

Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.


--------------------------------------------------------------------------------

Backdoor passwords

Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.

Password cracking software

The following software can be used to either crack or reset the BIOS on many chipsets. If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk.

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.
Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.


--------------------------------------------------------------------------------

Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.
Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.


--------------------------------------------------------------------------------

Overloading the KeyBoard Buffer

On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession.


--------------------------------------------------------------------------------

Jumping the Solder Beads on the CMOS

It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on the chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and the location of these solder beads can vary by manufacturer, so please check your computer and motherboard documentation for details. This technique is not recommended for the inexperienced and should be only be used as a "last ditch" effort.


--------------------------------------------------------------------------------

Using a professional service

If the manufacturer of the laptop or desktop PC can't or won't reset the BIOS password, you still have the option of using a professional service. Password Crackers, Inc., offers a variety of services for desktop and laptop computers for between $100 and $400. For most of these services, you'll need to provide some type of legitimate proof of ownership. This may be difficult if you've acquired the computer second hand or from an online auction.

How To Boot Xp Faster ------ updated

First of all, this tweak only apply to those who only have one HDD on their primary IDE channel (nothing else on device 0 or 1) and a CD-ROM and/or DVD-ROM on the secondary IDE channel. Each time you boot Windows XP, there's an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (%SystemRoot%Prefetch) and there's no need to erease any other files as the new prefetch option in XP really improves loading time of installed programs. We only want WindowsXP to boot faster and not decrease its performance. Thanks to Rod Cahoon (for the prefetch automation process...with a minor change of mine) and Zeb for the IDE Channel tweak as those two tricks, coupled together with a little modification, result in an EXTREMELY fast bootup:

1. Open notepad.exe, type "del c:windowsprefetch tosboot-*.* /q" (without the quotes) & save as "ntosboot.bat" in c:
2. From the Start menu, select "Run..." & type "gpedit.msc".
3. Double click "Windows Settings" under "Computer Configuration" and double click again on "Shutdown" in the right window.
4. In the new window, click "add", "Browse", locate your "ntosboot.bat" file & click "Open".
5. Click "OK", "Apply" & "OK" once again to exit.
6. From the Start menu, select "Run..." & type "devmgmt.msc".
7. Double click on "IDE ATA/ATAPI controllers"
8. Right click on "Primary IDE Channel" and select "Properties".
9. Select the "Advanced Settings" tab then on the device 0 or 1 that doesn't have 'device type' greyed out select 'none' instead of 'autodetect' & click "OK".
10. Right click on "Secondary IDE channel", select "Properties" and repeat step 9.
11. Reboot your computer.

WindowsXP should now boot REALLY faster.

How To Block Websties Without Software, block websites

Steps:

1] Browse C:\WINDOWS\system32\drivers\etc
2] Find the file named "HOSTS"
3] Open it in notepad
4] Under "127.0.0.1 localhost" Add 127.0.0.2 www.sitenameyouwantblocked.com , and that site will no longer be accessable.
5] Done!

-So-

127.0.0.1 localhost
127.0.0.2 www.blockedsite.com

-->www.blockedsite.com is now unaccessable<--


For every site after that you want to add, just add "1" to the last number in the internal ip (127.0.0.2) and then the addy like before.

IE: 127.0.0.3 www.blablabla.com
127.0.0.4 www.blablabla.com
127.0.0.5 www.blablabla.com

etc

How Long Has Your System Been Running?

Here's how you verify system uptime:

Click Start | Run and type cmd to open a command prompt.
At the prompt, type systeminfo

Scroll down the list of information to the line that says System Up Time.

This will tell you in days, hours, minutes and seconds how long the system has been up.

Note that this command only works in XP Pro, not in XP Home. You can, however, type net statistics workstation at the prompt in Home. The first line will tell you the day and time that the system came online.

Simple and useful tip

******************
at command prompt just type
dir /ah
if the list is too long u can use
dir /ah/p/w

Delete An "undeletable" File

Open a Command Prompt window and leave it open.
Close all open programs.
Click Start, Run and enter TASKMGR.EXE
Go to the Processes tab and End Process on Explorer.exe.
Leave Task Manager open.
Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.
At the command prompt type DEL where is the file you wish to delete.
Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
Close Task Manager.


Or you can try this

Open Notepad.exe

Click File>Save As..>

locate the folder where ur undeletable file is

Choose 'All files' from the file type box

click once on the file u wanna delete so its name appears in the 'filename' box

put a " at the start and end of the filename
(the filename should have the extension of the undeletable file so it will overwrite it)

click save,

It should ask u to overwrite the existing file, choose yes and u can delete it as normal


Here's a manual way of doing it. I'll take this off once you put into your first post zain.

1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:\*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

Create One-Click Shutdown and Reboot Shortcuts:

First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC.

But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this:

shutdown -r -t 01 -c "Rebooting your PC"
Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use.

I use this technique to create two shutdown shortcuts on my desktop—one for turning off my PC, and one for rebooting. Here are the ones I use:

shutdown -s -t 03 -c "Bye Bye m8!"
shutdown -r -t 03 -c "Ill be back m8 ;)!"

Switch
What it does

-s
Shuts down the PC.

-l
Logs off the current user.

-t nn
Indicates the duration of delay, in seconds, before performing the action.

-c "messagetext"
Displays a message in the System Shutdown window. A maximum of 127 characters can be used. The message must be enclosed in quotation marks.

-f
Forces any running applications to shut down.

-r
Reboots the PC.

Cracking Zip Password Files

Tut On Cracking Zip Password Files..
What is FZC? FZC is a program that cracks zip files (zip is a method of compressing multiple files into one smaller file) that are password-protected (which means you're gonna need a password to open the zip file and extract files out of it). You can get it anywhere - just use a search engine such as altavista.com.
FZC uses multiple methods of cracking - bruteforce (guessing passwords systematically until the program gets it) or wordlist attacks (otherwise known as dictionary attacks. Instead of just guessing passwords systematically, the program takes passwords out of a "wordlist", which is a text file that contains possible passwords. You can get lots of wordlists at www.theargon.com.).
FZC can be used in order to achieve two different goals: you can either use it to recover a lost zip password which you used to remember but somehow forgot, or to crack zip passwords which you're not supposed to have. So like every tool, this one can be used for good and for evil.
The first thing I want to say is that reading this tutorial... is the easy way to learn how to use this program, but after reading this part of how to use the FZC you should go and check the texts that come with that program and read them all. You are also going to see the phrase "check name.txt" often in this text. These files should be in FZC's directory. They contain more information about FZC.
FZC is a good password recovery tool, because it's very fast and also support resuming so you don't have to keep the computer turned on until you get the password, like it used to be some years ago with older cracking programs. You would probably always get the password unless the password is longer than 32 chars (a char is a character, which can be anything - a number, a lowercase or undercase letter or a symbol such as ! or &) because 32 chars is the maximum value that FZC will accept, but it doesn't really matter, because in order to bruteforce a password with 32 chars you'll need to be at least immortal..heehhe.. to see the time that FZC takes with bruteforce just open the Bforce.txt file, which contains such information.
FZC supports brute-force attacks, as well as wordlist attacks. While brute-force attacks don't require you to have anything, wordlist attacks require you to have wordlists, which you can get from www.theargon.com. There are wordlists in various languages, various topics or just miscellaneous wordlists. The bigger the wordlist is, the more chances you have to crack the password.
Now that you have a good wordlist, just get FZC working on the locked zip file, grab a drink, lie down and wait... and wait... and wait...and have good thoughts like "In wordlist mode I'm gonna get the password in minutes" or something like this... you start doing all this and remember "Hey this guy started with all this bullshit and didn't say how I can start a wordlist attack!..." So please wait just a little more, read this tutorial 'till the end and you can do all this "bullshit".

We need to keep in mind that are some people might choose some really weird passwords (for example: 'e8t7@$^%*gfh), which are harder to crack and are certainly impossible to crack (unless you have some weird wordlist). If you have a bad luck and you got such a file, having a 200MB list won't help you anymore. Instead, you'll have to use a different type of attack. If you are a person that gives up at the first sign of failure, stop being like that or you won't get anywhere. What you need to do in such a situation is to put aside your sweet xxx MB's list and start using the Brute Force attack.
If you have some sort of a really fast and new computer and you're afraid that you won't be able to use your computer's power to the fullest because the zip cracker doesn't support this kind of technology, it's your lucky day! FZC has multiple settings for all sorts of hardware, and will automatically select the best method.

Now that we've gone through all the theoretical stuff, let's get to the actual commands.


--------------------------------------------------------------------------------
Bruteforce
--------------------------------------------------------------------------------


The command line you'll need to use for using brute force is:

fzc -mb -nzFile.zip -lChr Lenght -cType of chars

Now if you read the bforce.txt that comes with fzc you'll find the description of how works Chr Lenght and the Type of chars, but hey, I'm gonna explain this too. Why not, right?... (but remember look at the bforce.txt too)

For Chr Lenght you can use 4 kind of switches...

-> You can use range -> 4-6 :it would brute force from 4 Chr passwors to 6 chr passwords
-> You can use just one lenght -> 5 :it would just brute force using passwords with 5 chars
-> You can use also the all number -> 0 :it would start brute forcing from passwords with lenght 0 to lenght 32, even if you are crazy i don't think that you would do this.... if you are thinking in doing this get a live...
-> You can use the + sign with a number -> 3+ :in this case it would brute force from passwords with lenght 3 to passwords with 32 chars of lenght, almost like the last option...

For the Type of chars we have 5 switches they are:

-> a for using lowercase letters
-> A for using uppercase letters
-> ! for using simbols (check the Bforce.txt if you want to see what simbols)
-> s for using space
-> 1 for using numbers


Example:
If you want to find a password with lowercase and numbers by brute force you would just do something like:

fzc -mb -nzTest.zip -l4-7 -ca1

This would try all combinations from passwords with 4 chars of lenght till 7 chars, but just using numbers and lowercase.

*****
hint
*****

You should never start the first brute force attack to a file using all the chars switches, first just try lowercase, then uppercase, then uppercase with number then lowercase with numbers, just do like this because you can get lucky and find the password much faster, if this doesn't work just prepare your brain and start with a brute force that would take a lot of time. With a combination like lowercase, uppercase, special chars and numbers.


--------------------------------------------------------------------------------
Wordlis
--------------------------------------------------------------------------------

Like I said in the bottom and like you should be thinking now, the wordlist is the most powerfull mode in this program. Using this mode, you can choose between 3 modes, where each one do some changes to the text that is in the wordlist, I'm not going to say what each mode does to the words, for knowing that just check the file wlist.txt, the only thing I'm going to tell you is that the best mode to get passwords is mode 3, but it takes longer time too.
To start a wordlist attak you'll do something like.

fzc -mwMode number -nzFile.zip -nwWordlist

Where:

Mode number is 1, 2 or 3 just check wlist.txt to see the changes in each mode.
File.zip is the filename and Wordlist is the name of the wordlist that you want to use. Remember that if the file or the wordlist isn't in the same directory of FZC you'll need to give the all path.

You can add other switches to that line like -fLine where you define in which line will FZC start reading, and the -lChar Length where it will just be read the words in that char length, the switche works like in bruteforce mode.
So if you something like

fzc -mw1 -nztest.zip -nwMywordlist.txt -f50 -l9+

FZC would just start reading at line 50 and would just read with length >= to 9.

Example:

If you want to crack a file called myfile.zip using the "theargonlistserver1.txt" wordlist, selecting mode 3, and you wanted FZC to start reading at line 50 you would do:

fzc -mw3 -nzmyfile.zip -nwtheargonlistserver1.txt -f50





--------------------------------------------------------------------------------
Resuming
--------------------------------------------------------------------------------

Other good feature in FZC is that FZC supports resuming. If you need to shutdown your computer and FZC is running you just need to press the ESC key, and fzc will stop. Now if you are using a brute force attack the current status will be saved in a file called resume.fzc but if you are using a wordlist it will say to you in what line it ended (you can find the line in the file fzc.log too).
To resume the bruteforce attack you just need to do:

fzc -mr

And the bruteforce attack will start from the place where it stopped when you pressed the ESC key.
But if you want to resume a wordlist attack you'll need to start a new wordlist attack, saying where it's gonna start. So if you ended the attack to the file.zip in line 100 using wordlist.txt in mode 3 to resume you'll type

fzc -mw3 -nzfile.zip -nwwordlist.txt -f100

Doing this FZC would start in line 100, since the others 99 lines where already checked in an earlier FZC session.


Well, it looks like I covered most of what you need to know. I certainly hope it helped you... don't forget to read the files that come with the program

How To: Change Your Ip In Less Then 1 Minute

1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "command" and hit ok

You should now be at an MSDOS prompt screen.

4. Type "ipconfig /release" just like that, and hit "enter"
5. Type "exit" and leave the prompt
6. Right-click on "Network Places" or "My Network Places" on your desktop.
7. Click on "properties"

You should now be on a screen with something titled "Local Area Connection", or something close to that, and, if you have a network hooked up, all of your other networks.

8. Right click on "Local Area Connection" and click "properties"
9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
10. Click on "Use the following IP address" under the "General" tab
11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).
12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
13. Hit the "Ok" button here
14. Hit the "Ok" button again

You should now be back to the "Local Area Connection" screen.

15. Right-click back on "Local Area Connection" and go to properties again.
16. Go back to the "TCP/IP" settings
17. This time, select "Obtain an IP address automatically"
tongue.gif 18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address

With a little practice, you can easily get this process down to 15 seconds.

P.S:
This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

10 reasons why PCs crash U must Know

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

4 Hard disk drives

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5 Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6 Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

7 Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8 Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9 Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10 Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

How To Fix A PC That Fails To Complete Bootup

Did your PC just fail to boot up completely ? This is one of the common problems which Windows users face time and again. Whenever this happens, you are almost always accompanied by a text error message (this error message is known as Boot Time Error Message). If you get a Boot Time Error Message, this indicates that the output from the graphics card and that the motherboard is probably OK.

Next you have to observe what message is on the screen when the boot procedure stops. In most cases they are self-explanatory, such as Invalid System Disk or Disk Error when you boot up with a floppy disk inserted in the floppy disk drive. Sometimes though, they can be more cryptic but will often give some indication of where the problem lies.

An error message can be produced by different parts of the system, depending on how far into the boot process the system gets before the problem occurs. Usually error messages are produced by the BIOS, as it is responsible for most of the boot procedure functions. However, other error messages are specific to the operating system and are known as Run Time error Messages.

There are many thousands of individual error messages - some more common than others. However, bear in mind that since the exact wording of an error message can be changed by the manufacturer of each system, there are a lot of variations on the same theme. If you are not sure that you can handle the system alone, it is advicable to take your PC to a professional.

A Cheap Route to Robust LEDs


Organic light-emitting diodes (OLEDs) are steadily making their way into commercial devices like cell phones and flat-screen displays. They're fabricated with layers of organic polymers, which make them flexible, and they use less power and less expensive materials than liquid crystal displays.

The downside is that because the polymers react easily with oxygen and water, OLEDs are expensive to produce--they have to be created in high-vacuum chambers--and they need extra protective packaging layers to make sure that once they're integrated into display devices, they don't degrade when exposed to air or moisture.

MIT chemical-engineering professor Karen Gleason and MIT postdoc Sreeram Vaddiraju have developed a process that aims to solve the problems of high fabrication costs and instability for OLEDs while still maintaining their flexibility. Gleason's solution is a hybrid light-emitting diode, or HLED. The device would incorporate both organic and inorganic layers, combining the flexibility of an OLED with the stability of an inorganic light-emitting material. "The idea is to have a mixed bag and capture the qualities that allow inexpensive fabrication and stability," Gleason says.

Gleason starts with a substrate of electrically conducting organic polymer, which she creates through a chemical vapor deposition process in a low-vacuum chamber. It's the only step in the process that requires a vacuum, which should make the approach cheaper than conventional methods. For the light-emitting layer, Gleason uses quantum dots, nanocrystals of inorganic semiconductors; each quantum dot can be "tuned" to emit certain frequencies of light. Although quantum dots are inflexible themselves, they're so small--two to six nanometers across--that even arranging them side by side in a continuous film still allows for flex in the material.

While using quantum dots in light-emitting devices isn't new, Gleason's technique is. The problem is how to get the dots to stick onto a substrate in a uniform, even layer, without moving. Vaddiraju says that they use "molecular wiring." Instead of just laying down the quantum dots on top of the polymer substrate, the scientists use linker molecules between the layers to chemically bond the quantum-dot layer and the polymer together.

This "cross-linking" molecule between the layers is "a beautiful evolution of the present structures," says Vladimir Bulovic, an associate professor of electrical engineering at MIT and the first to demonstrate practical use of quantum dots in optoelectronic devices. Bulovic's research has depended on other methods of depositing quantum dots: dropping the dots onto a fast-spinning substrate, called spin casting, and, more recently, stamping them onto a surface.

The perfect weapon against SPAM!

SPAM messages waste time, disrupt work and often carry malicious attachments or links that threaten your systems.

We have recently launched a SPAM filtering solution which uses technology which ensures that your emails are filtered of SPAM before they get to you, using the latest anti-spam technology with 5 layers of filtering, thereby producing a number of benefits.
- The load (or pressure) on your server to process all the SPAM emails is decreased, therefore you may see an increase in system speed.
- The filtering screens Email for malicious software - such as computer viruses and spyware, and phishing (fraud based emails).
- The service is relatively fast to set up and can be activated in 1 or 2 days with the results starting to take effect within 2 working days.
- The SPAM filtering process uses the latest technology (IronPort Mail Security)and is highly successful, ensuring that approximately 95% (or more) of your SPAM will be rejected or captured. As SPAM continues to grow as a business challenge this service evolves to combat the increasing new threats.

Kind of feedback we have been receiving sound like this:
“Daniel this is working like a dream – thanks heaps. The boys are only getting one or two spam a day if any.”
“The spam is a LOT better, thanks very much. We only received 2 in the last 2 days they both said spam in front of them.”
“I had only 1 spam email today, and it went directly into my junk email folder. I have asked around and everyone is getting the same”

Firefox users gain location tool

Mozilla, the company behind the Firefox browser, has released technology that helps websites detect the physical location of computers.

The system will allow users, for instance, to find local restaurants when they travel to a new town.

The Geode project is an experimental add-on ahead of a full blown launch of geolocation technology in version 3.1 of Firefox.

Users will have control over how much location information they give.

It uses technology from a firm called Skyhook which works out a computer's location from nearby wireless networks.

Its so-called Loki system can determine location within seconds with an accuracy of about 10 to 20 metres.

'Unbreakable' Encryption Unveiled

A Perfect secrecy has come more closer with the launch of the world's first computer network protected by unbreakable quantum encryption .

Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.

The network connects six locations across Vienna and in the nearby town of St Poelten, using commercial fibre optic cables.

These are typically based on complex mathematical procedures which are extremely hard for people to crack

But quantum systems use the laws of quantum theory, which is supposed to be inherently unbreakable.

Anton Zeilinger, of Vienna University said : "Real breakthroughs are not found because you want to develop some new technology, but because you are curious and want to find out how the world is"

The basic idea of quantum cryptography was worked out 25 years ago by Charles Bennett of IBM and Gilles Brassard of Montreal University,,they were also in Vienna to see the network in action.

"All quantum security schemes are based on the Heisenberg Uncertainty Principle, on the fact that you cannot measure quantum information without disturbing it," he explained.

"Because of that, one can have a communications channel between two users on which it's impossible to eavesdrop without creating a disturbance. An eavesdropper would create a mark on it. That was the key idea."

Numerical key

From the detected photons, a totally secret numerical key can be distilled, which encodes the users' data much like the keys used in normal computer networks do.

The advantage is that no-one else can know the key without revealing themselves.

As we saw in the demonstration: when an intruder did try to listen in on the quantum exchange, photons became scrambled, and a rise in the error rate at the node detectors signalled the attack. The system automatically shut down without being compromised.

More importantly, the demonstration also showed that the network is robust.

If one quantum link breaks down, the connections can be re-routed via other nodes, much as phone calls get re-routed automatically through a telecoms network, so that any two users on the network can remain in continuous secure contact.

Dr Hannes Huebel of Vienna University, explained how robustness is now as important as security in the development of quantum encryption systems.

"We are constantly in touch with insurance companies and banks, and they say it's nearly better that they lose 10 million euros than if the system is down for two hours, because that might be more damaging for the bank," said Dr Huebel.

"So that's what we have to prove, that we have a reliable system that delivers quantum keys for several weeks without interruption, and then they might be more interested."

Polarised light

The final element of the EU-sponsored project (called SECO-QC) was the interconnection of different realisations of quantum cryptography.

There are many ways photons of light can encode a numerical key: through the direction they're polarised (like Polaroid glasses) for example, or the precise timing of their arrival.

Different schemes have different strengths and weaknesses, and a viable network would have handle whatever individual users choose to use, explained the project's director, Christian Monyk - just as a mobile phone network has to handle handsets from many manufacturers.

Quantum cryptography is a surprising outgrowth of recondite arguments that bounced around for decades about the meaning of quantum mechanics.

Albert Einstein, who discovered the quantum properties of photons of light - indeed, discovered the very concept of the photon - always resisted quantum theory's spooky behaviour, "God does not play dice", being among his oft-quoted objections.

"Real breakthroughs are not found because you want to develop some new technology, but because you are curious and want to find out how the world is," Dr Zeilinger said.
