How to Break WinRAR Package Password in Ubuntu (Easy Way)

It is easy to break your Winrar Password Package in Ubuntu. You can use
this method in case you forget your Winrar Password or kind like that.
Ok, let's get started.

First, you must know that software that will perform the RAR Package
Crack, the software name is "RarCrack". And this is the method to
download and install RARCRACK. You can download the latest version (0.2)
from this http://rarcrack.sourceforge.net/ .

Or simply follow this simple tutorial to perform the installation.

First, download the rarcrack 0.2 by pasting this following code:

wget http://superb-east.dl.sourceforge.net/sourceforge/rarcrack/rarcrack-0.2.tar.bz2

Extract the RarCrack

tar xvjf rarcrack-0.2.tar.bz2

Get into the RarCrack Folder

cd rarcrack-0.2

install some needed dependencies by typing this following code:

sudo apt-get install libxml2-dev

Install the RarCrack

make ; sudo make install

Alright! That's the end of RarCrack Installation. Ok, that's not
entirely true, there's one of the most important part that you forget,
the cracking part ;) . To crack or break the RAR Package Password, type
in terminal:

rarcrack /home/UserName/example.rar

Just simply put your .rar directory and perhaps if it's not working try
to rename your rar file, it probably will help.

This software is also works for other Package (zip and 7z), just simply
replace .rar into .zip or .7z in case you must break zip or 7z passwd. 

How to enable/disable Ctrl+Alt+Backspace in Ubuntu 9.10 (Karmic)

Ctrl+Alt+Backspace (i.e. the shortcut which was used to restart the X
server) has to be enabled in a different way with respect to previous
releases of Ubuntu.

This is due to the fact that "DontZap" is no longer an option in the X
server and has become an option in XKB instead.

Using GNOME

* Get to the System->Preferences->Keyboard menu.

* Select the "Layouts" tab and click on the "Layout Options" button.

* Then select "Key sequence to kill the X server" and enable "Control +
Alt + Backspace".

Using KDE

* Launch "systemsettings"

* Select "Regional & Language".

* Select "Keyboard Layout".

* Click on "Enable keyboard layouts" (in the Layout tab).

* Select the "Advanced" tab. Then select "Key sequence to kill the X
server" and enable "Control + Alt + Backspace".

Using the command line

You can type the following command to enable Zapping immediately.

setxkbmap -option terminate:ctrl_alt_bksp

If you're happy with the new behaviour you can add that command to your
~/.xinitrc in order to make the change permanent.

Using HAL

You can add the following line
in /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi (inside the
<match key="info.capabilities" contains="input.keys"> section):

<merge key="input.xkb.options"

Compress and Split Files in Ubuntu 9.10

 

01. cd films/split-files (change the filepath to where you want to keep
the split files)

02. tar -cvj /home/username/films/large-files.avi | split -b 640m -d – "large-files.tar.bz."

You will now see several files appearing at the split-files folder, each
with file size of 640MB and with filenames large-files.tar.bz.00,
large-files.tar.bz.01, large-files.tar.bz.02, etc.

To recover and extract the split files, type

#cat large-files.tar.bz.* > large-files.tar.bz
#tar -xvj large-file.tar.bz

and you can get the original file back.
