How to Install Aircrack ng in Ubuntu

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the PTW attack, thus making the attack much faster compared to other WEP cracking tools.

In fact, Aircrack-ng is a set of tools for auditing wireless networks.

install  commands

1 - sudo apt-get install build-essential
2 - sudo apt-get install libssl-dev
3 - wget http://download.aircrack-ng.org/aircrack-ng-1.1.tar.gz

CFLAGS ?= -g -W -Wall -Werror -O3

Delete the -Werror variable, so that the line now looks like the following. Save and exit.

CFLAGS ?= -g -W -Wall -O3

route analysis with 0trace.sh in Kali Linux

0trace.sh is a shell script written by Michal Zalewski. It is a reconnaissance / firewall bypassing tool that enables hop enumeration ("traceroute") within an established TCP connection, such as a HTTP or SMTP session. This is opposed to sending stray packets, as traceroute-type tools usually do. In case of a successful scan, 0trace provides useful additional servers for the penetration tester.

How to install screenlets in ubuntu/linux

Screenlets are small owner-drawn applications (written in Python) that can be described as "the virtual representation of things lying/standing around on your desk". Sticky notes, clocks, rulers, ... the possibilities are endless.

The goal of the Screenlets base-classes is to simplify the creation of fully themable mini-apps that each solve basic desktop-work-related needs and generally improve the usability and eye-candy of the modern composited Linux-desktop.

Features:

• Real applications, no HTML-"widgets"
• Easy to use, easy to develop
• Full compositing support
• Works with any composited X desktop (compiz, xfce4, ...)
• Works also on non-composited desktop
• Included ability to apply themes (SVG, PNG or mixed)
• Fully scalable when using SVGs
• Embedded drag&drop-support
• Automated storing of options (using ini or GConf)
• Controllable through customizable D-Bus service
• Can be used together with compiz' widget-plugin to create a Dashboard-like feature as seen on OS X
• Uses Cairo and GTK2 for drawing and windowing
