If you are School/College/University students, you may curious to hack the admin password in your college or school system. This post is going to help you to crack the any type of windows accounts passwords. Learn how to hack the windows admin password like a geek.


Requirements:

• BackTrack Linux 4 or 5. Download it from http://backtrack-linux.org
• Two Pen drives [if you are going to test in your own system, one pen drive is enough]
• Xp Free Fast RainBow table [tables_xp_free_fast.zip]. Download it from here:http://ophcrack.sourceforge.net/tables.php

To find out which shared libraries a program requires, type

    ldd `which _program_`

    (make sure you use the back single quote `, not the apostrophe, ')

    The which command just gives the full path for a given _program_
    ldd lists library dependencies.

    Don't they get a simple `connection refused' ?
    I'd only expect a timeout on machines that are down.

    % grep -i ident /etc/sendmail/config.m4
    define(`confTO_IDENT', 0s)

Allowing non-root users to shutdown a Linux box.

    1. As root create a group shutdown.
       #addgroup shutdown

    2. Put /sbin/shutdown into the group shutdown.
       #chown root.shutdown /sbin/shutdown

    3. Change accessrights to make /sbin/shutdown setuid and disallow
       other users from executing shutdown.
       #chmod 4754 /sbin/shutdown

    4. Make a link from /bin/shutdown to /sbin/shutdown
    #ln -s /sbin/shutdown  /bin/shutdown

    Now anyone belonging to the group shutdown can execute shutdown but I just will
    allow the person in control of the keyboard to be able to issue the shutdown
    command. You might prefer something else.

    For the following to work you need to have "shadow password" installed but I
    believe most have it.

    5. Edit the file login.defs. Near the end of this file locate the line
    #CONSOLE_GROUPS       floppy:audio:cdrom
    Remove the hashsign and add the group shutdown to this line and you get:
    CONSOLE_GROUPS        floppy:audio:cdrom:shutdown

    Thats it. Everyone logged in via the console will belong to these groups so
    you need not add anyone to them. I believe this is better than to just add
    users to the group shutdown.

    pppconfig checks /etc/resolv.conf.  If it exists and has nameservers it
    doesn't ask for new ones.
