How to hack or crack Wi-Fi Password Using Debian Linux

Posted by Rakesh under FYI, Howto, Linux /GNU

Hacking Wi-Fi Password Using Debian Linux – I know a lot of you out there would love to know how to hack or crack Wi-Fi passwords from coffee shops or just about any place with managed or secured network. Today, here I will feature Linux based hacking tool which can help you crack Wi-Fi passwords be it WEP or WPA protected. I’m going to share with you some of my favorite wireless tools that can be used to hack Wi-Fi password using Debian or any other Linux distribution:

Aircrack-ng
Aircrack-ng (a fork of aircrack) is my main tool for cracking Wi-Fi passwords. It has a wireless network detector, a packet sniffer, WEP and WPA/WPA2-PSK cracker, and an analysis tool for 802.11 wireless LANs. Aircrack-ng works with any wireless card whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.

Kismet
Kismet is a really good network detector, packet sniffer, and intrusion detection system for 802.11 wireless LANs. It will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b, 802.11g, and 802.11n traffic. Kismet works in passive mode, which means it is capable of detecting the presence of both wireless access points and wireless clients without sending any loggable packets.

SWScanner
SWScanner is specifically designed to make the whole wardriving process a lot easier. It is also intended to manage many tasks related to wireless networking. SWScanner is compatible with NetStumbler files and can be integrated with GPS devices.

These are only three of the many wireless tools that can get you going in no time, so feel free to explore.

I will give you a step-by-step instruction on how to hack or crack WiFi password using Debian.

Speed Up Your Web Browsing with OpenDNS

Posted by Rakesh under FYI, Linux /GNU, Technology, Uncategorized

Are you looking for a faster way to browse the Internet and have pages load faster? If so, you might be interested in trying out OpenDNS (208.67.222.222, 208.67.220.220). Adding OpenDNS to your router or home computer will speed up your web browsing.

DNS (Domain Name System) translates an IP address to an easy to remember hostname. If you use your ISPs DNS settings by default, it may not be the fastest way to get to your favorite sites.

First, let you know – What Is OpenDNS?

Like many people, I use OpenDNS on my home network. It is a free DNS service that translates the URLs of Web pages into IP addresses.

OpenDNS theoretically helps speed up Web browsing by using better DNS servers to resolves URLs faster than your Internet Service Provider (ISP). The increase is probably too small for you to notice on a regular basis, however. More importantly, the service gives you better control over the Web sites you and your family visits, and contains built-in controls to protect against hackers hijacking your browser.
In operation for just over five years, OpenDNS now is serving upwards of 20 billion DNS queries per day. I’ve never experienced an outage or performance problem. Kudos to the folks at OpenDNS for running a fine service.

Read this post to add OpenDNS (DNS Servers: 208.67.222.222, 208.67.220.220) to your PC to Speed up Web browsing.

Window Manager: Getting started with Openbox

Posted by Rakesh under FYI, Linux /GNU, Technology

Get the packages

First install the main package, and any or none of the three optional extra utilities.

In Debian/Ubuntu do:

## required installation:

sudo apt-get install openbox

## optional installation:

sudo apt-ge install obconf gmrun pcmanfm

In other linux installations you can probably use ‘yum’ instead of ‘apt-get’.

Set up your configuration

Installing openbox will get you a set of default system wide configuration files in

/etc/xdg/openbox

You can copy them to your own directory, where you can edit them:

mkdir -p ~/.config/openbox

cp -p /etc/xdg/openbox/* ~/.config/openbox

There are three files required for a minimal configuration

autostart.sh
run once just before openbox starts up
Use a delay to launch X11 windows, and background them,
so that the don’t come up until openbox has started.
I have some example commands in here

menu.xml
You can define exactly one menu to be invoked in the root
window, using the right mouse button. I have modified this
to make it very easy to invoke gmrun, to launch a command,
and to start an xterm window.
My modified version of the default is here

rc.xml
This is the main configuration file in which you can define
how menus should look, how many virtual desktops you want,
which keyboard actions you want, etc. My version defines two
ways of launching an xterm window, one big and one small, using
CTRL+F1 and CTRL+F2 respectively. I also cycle left and
right through desktops using CTRL+Left and CTRL+Right.
I have included an option to run ‘gmrun’ using CTRL+F4
My modified version of the default is here

PERMISSION AND WARNING
Anyone who so desires has my permission to copy and use any of the example files provided here, most of which are themselves slightly edited versions of files that came with OpenBox.

Please check the executable files before you use them, especially autostart.sh and the .xinitrc file mentioned below.

Using gmrun
One of the nice things about using gmrun is that it maintains a history of commands. It also supports tab completion, and if you give it a url it will launch firefox, etc. I have slightly modified the default initialization file, which is

~/.gmrunrc

to specify a location for the panel and wider default text-box width. My version, based on the default version, is here.

Sample .xinitrc
A sample ~/.xinitrc file invoked when you start X from a console, is here. If you fetch it make it executable and remove the comments at the top.

Tar file with sample config files
A tar file containing my tailored extensions to Openbox and a sample .xinitrc file is available here: configfiles.tar.gz

Current contents

-rwxr-xr-x 2087 2009-01-22 17:57:34 dotxinitrc
drwxr-xr-x 0 2009-01-22 04:11:41 dotconfig-openbox-files/
-rw-r--r-- 1768 2009-01-20 09:46:33 dotconfig-openbox-files/autostart.sh
-rw-r--r-- 2861 2009-01-22 03:55:14 dotconfig-openbox-files/menu.xml
-rw-r--r-- 25571 2009-01-22 04:49:49 dotconfig-openbox-files/rc.xml
-rw-r--r-- 1391 2009-01-20 03:27:22 dot-gmrunrc-sample
drwxr-xr-x 0 2009-01-22 15:41:34 CLO/
drwxr-xr-x 0 2009-01-22 15:41:50 CLO/openbox-3/
-rw-r--r-- 5050 2009-01-22 15:37:54 CLO/openbox-3/themerc

I hope it is clear from the rest of this file what to do with each of those. But just in case, here is a summary:


# create the required directories, in case you don't have them

cd /download

tar xvzf configfiles.tar.gz

mkdir -p ~/.themes ~/.config/openbox

## put the CLO theme in place

mv CLO ~/.themes

mv dotconfig-openbox-files/* ~/.config/openbox

## config file for gmrun

mv dot-gmrunrc-sample ~/.gmrun

## if you want to start up the X window system directly from
## a console terminal using startx

mv dotxinitrc ~/.xinitrc

Before trying out the scripts please check all the files, in case of corruption, or in case they invoke utilities not available on your machine, especially these two ’startup’ files: ~/.xinitrc ~/.config/openbox/autostart.sh

Make a mobile version of your Wordpress blog or site

Posted by Rakesh under FYI, Howto, Uncategorized

Last week, while seeing my site in my BlackBerry smartphone and iPhone, it seemed weird to me. Then I decided to make my site Mobile friendly. Saturday night on the last weekend, I created a mobile version of my blog – A|RAKESH’s Weblog.

Are you looking out for ways to make your Wordpress blog or site Mobile friendly? Here is the solution for you.

If you are using WordPress for your site and you are looking for a mobile version (e.g. for iPhone, BlackBerry Smartphones, Google Phone, Nokia, etc) of your existing site to use, you should really consider WordPress Mobile Edition OR WordPress Mobile Pack for WordPress.

WordPress Mobile Edition Plugin 3.1 is compatible with WordPress 2.9.1 (WordPress 2.9.1 + Plugin 3.1 = works).

You can download WordPress Mobile Edition Plugin 3.1 from here.

WordPress Mobile Edition is a plugin that shows an interface designed for a mobile device when visitors come to your site on a mobile device.

Mobile browsers are automatically detected, the list of mobile browsers can be customized on the settings page.

Read for How to install a WordPress plugin

1. Drop the wp-mobile.php file in your wp-content/plugins directory
2. Drop the carrington-mobile-(version #) directory in your wp-content/themes directory
3. Click the ‘Activate’ link for WordPress Mobile Edition on your Plugins page (in the WordPress admin interface)

API

There is a filter cfmobi_check_mobile that allows you to affect if a mobile browser is detected.



function your_mobile_check_function($mobile_status) {

// do your logic, set $mobile_status to true/false as needed

return $mobile_status;
}
add_filter(’cfmobi_check_mobile’, ‘your_mobile_check_function’);

There is an action cfmobi_settings_form that allows you to add to the settings page for this plugin. Handling form posts and other activities from anything you add to this form should be done in your plugin.



function your_settings_form() {
// create your form here – don’t forget to catch the form submission as well
}
add_action(’cfmobi_settings_form’, ‘your_settings_form’);

Notes:

1. As iPhones and other “touch” browsers of version 3.0 support.

2. You can also create a link that forces someone to see the mobile version. The link can be added to your theme by using the akm_mobile_link() template tag:

<?php in (function_exists(’cfmobi_mobile_link’) { cfmobi_mobile_link(); } ?>

Note that this does not work if you have WP Cache enabled.

Enjoy mobile version of your site !! … :-)

Read for How to test whether the mobile version of your blog or site is correctly working or not. For this, you can use Firefox browser’s about:config preference.
