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.

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.

    >From the diald man page:

           restrict <start> <end> <weekdays> <monthdays> <months>

           or-restrict <start> <end> <weekdays> <monthdays> <months>
                  Normally filter  rules  apply  at  all  times.  The
                  restrict statement makes all filter rules following
                  the restrict statement, up  to  the  next  restrict
                  statement, apply only at the times indicated by the
                  restrict statement.

    Yes.

    > and how?

    Turn on the command fifo and then send commands such as 'block' and
    'unblock' from cron jobs.  man diald and man diald-control.

Is it possible to set some parameter to overcome this time

    Try 'tzconfig'.

     Try "man setserial". It looks like your serial port is not getting
    configured properly. I think serial ports in Linux default to pretty
    conservative values. Try setting the rate to at least 38400. I'll bet that
    this is the main source of the problem.

     After that, start looking at init strings for the modem and such. The
    factory default settings ought to be okay, but there may be some things
    you can play with.

     Finally, there are a few options for pppd that can result in improved
    performance. Make sure that your asynchmap is 0 if at all possible. See if
    Van Jacobsen header compression is allowed. (The man page explains this
    stuff...)

1. Use Linuxconf for doing the following. You can start Linuxconf from the Gnome Programs Menu ->System Submenu or from the K Menu or by typing 'linuxconf' at the prompt (bash).
2. Select Filesystems from the left panel.
3. Then click on Access local drives in the left panel.
4. You would be shown the current local filesystems that are recognized by Linux. Click on Add button
5. After clicking Add you will be presented with a tabbed window. In the tab named Base (This name might
6. Change in future Linux distributions) enter the partition name as /dev/hda5 (hda5 is the one that I want).
7. Enter the type as vfat (this makes long file names to be recognized under Linux)
8. Select mount point as /mnt/win (Click yes if it asks you to create a directory)
9.  In the tab named Options, Deselect 'Not mount at boot time' .. so that every time your machine starts      this filesystem is available.
10. Also Uncheck 'read only'.. if you want to write to that partition from within Linux
11. Finish the settings by clicking on Ok or Finish.
