Portable USB Pendrivelinux Workingt

by hardik davra

This tutorial enables a user to boot and run a Portable USB Pendrivelinux compilation (based on Debian), directly from a folder on a portable USB device, USB flash drive, external hard drive, internal hard drive, Ipod, etc… all without ever restarting your Windows computer. In addition, the user can install new programs, make changes and save personal files, allowing the operating system and any changes to be optionally restored on the next boot.
Using this tutorial, Pendrivelinux can be run from within Windows 98, 2000, NT, XP or Vista without rebooting. It runs from its own directory requiring absolutely no installation on the host PC. This is the perfect solution for those whose computer can not boot from a USB flash drive.
Update 09/27/07: Now works on systems using Windows Vista as the host.
10/30/07 New Release: New release includes intro and exit sounds, nuovo iconset, OSX like theme, right click run as root, new boot menu and much more.

How to Crack Linux Password

by hardik davra


If you’ve ever got stuck on the Login screen of your Linux system, as you don’t know the System password, don’t worry now. Its very easy to crack the password in Linux system.
All it takes is adjusting the boot parameters slightly and typing a command or two. Just follow the below given commands, and the work would be done.


1.Reboot your computer, and then as soon as you see the GRUB     Loading screen, make sure to hit the ESC key so that you can get to the menu.





Now you have two options:
Root Shell Method
  1. If you have the option, you can choose the “recovery mode” item on the menu, usually found right below your default kernel option.
  2. Then choose “Drop to root shell prompt” from this menu (This is called the Single User Mode).
  3. This should give you a root shell prompt.
Alternate Root Shell Method
If you don’t have the recovery mode option, this is the alternate way to manually edit the grub options to allow for a root shell.
  1. First you’ll have to make sure to choose the regular boot kernel that you use (typically just the default one), and then use the “e” key to choose to edit that boot option.
  2. Now just hit the down arrow key over to the “kernel” option, and then use the “e” key to switch to edit mode for the kernel option.
    3. Grub Details
  3. Now in the next screen that you see, you have to remove the “ro quiet splash” part with the backspace key, and then add this onto the end:
    rw init=/bin/bash
    (On some versions of Linux, you might have other shells as the default shell. So you have to type the above line accordingly. But most Linux versions have the “bash” shell as the default shell.)
  4. Once you hit enter after adjusting the kernel line, you’ll need to use the B key to choose to boot with that option.
  5. At this point the system should boot up very quickly to a command prompt.
You are now at the Root Shell Prompt (also called the Single User Mode)
Now Reset the Password
  1. Once you are the Root Shell Prompt, by following any of the above given method, you can use following command to reset the password of any user account:
    passwd username
  2. After the command is successful, type the following command to make sure the changes are written to the hard disk, before you reboot the computer:
    sync
  3. Now reboot the computer using the command:
    reboot -f
Once the computer restarts, you shall be able to login from the account, for which you had changed the password

BackTrack 5 Released – The Most Advanced Linux Security Distribution & LiveCD

by hardik davra


All hacking tool are available in bt5


We have of course been following BackTrack since the very early days, way back in 2006 when it was just known as BackTrack – A merger between WHAX and Auditor.  They’ve come a long way and BackTrack is now a very polished and well rounded security distro, most of the others have dropped off the map leaving BackTrack as the giant in the security LiveCD space.
The last major release was BackTrack Final 4 Released – Linux Security Distribution – back in January 2010.
The BackTrack Dev team has worked furiously in the past months on BackTrack 5, code name “revolution” – they released it on May 10th. This new revision has been built from scratch, and boasts several major improvements over all our previous releases. It’s based on Ubuntu Lucid LTS – Kernel 2.6.38, patched with all relevant wireless injection patches. Fully open source and GPL compliant.
The interesting part for me is that the new .ISO downloads offer multiple versions, including a choice between GNOME and KDE desktops and the images include ARM, 32-Bit and 64-Bit versions.
New in Version 5 :
  • Based on Ubuntu 10.04 LTS
  • Linux kernel 2.6.38 (with wireless injection patches)
  • KDE 4.6
  • GNOME 2.6
  • 32-bit and 64-bit support
  • · Metasploit 3.7.0
  • Forensics mode (a forensically sound instance)
  • Stealth mode (without generating network traffic)
  • Initial ARM image of BackTrack (for Android-powered devices)
