    Default Hello Sir

    Please have a look at this:

    A lost root password could be a bad day

    If that fails, try these steps:

    How-To: Recover root password under linux with single user mode


    It happens sometime that you can't remember root password. On Linux, recovering root password can be done by booting Linux under a specific mode: single user mode.
    This tutorial will show how to boot Linux in single user mode when using GRUB and finally how to change root password.
    During normal usage, a Linux OS runs under runlevels between 2 and 5 which corresponds to various multi-user modes. Booting Linux under runlevel 1 will allow one to enter into a specific mode, single user mode. Under such a level, you directly get a root prompt. From there, changing root password is a piece of cake.
    1. Entering Runlevel 1

    Some Linux distribution, such as Ubuntu for instance, offer a specific boot menu entry where it is stated "Recovery Mode" or "Single-User Mode". If this is your case, selecting this menu entry will boot your machine into single user mode, you can carry on with the next part. If not, you might want to read this part.
    Using GRUB, you can manually edit the proposed menu entry at boot time. To do so, when GRUB is presenting the menu list (you might need to press ESC first), follow those instructions:
    use the arrows to select the boot entry you want to modify.
    press e to edit the entry
    use the arrows to go to kernel line
    press e to edit this entry
    at the end of the line add the word single
    press ESC to go back to the parent menu
    press b to boot this kernel
    The kernel should be booting as usual (except for the graphical splash screen you might be used to), and you will finally get a root prompt (sh#).
    Here we are, we have gained root access to the filesystem, let's finally change the password.
    2. Changing Root Password

    As root, changing password does not ask for your old password, therefore running the command:
    # passwd

    will prompt you for your new password and will ask you to confirm it to make sure there is no typo.
    That's it, you can now reboot your box and gain root access again

    Default

    The default password is your own normal account password. Just type the following to become root user:
    Code:
    sudo -s
    If you currently logged in as vivek user, type vivek's password.
