How to compile Reaver under Ubuntu 12.04 (and aircrack-ng)

This is a quick how-to compile and install Reaver under Ubuntu 12.04

Steps:

1.    download source
2.    install required libraries and tools
3.    download and build aircrack-ng
4.    compile and install
5.    run

Download Source

First you need to download the latest source from http://code.google.com/p/reaver-wps/

    wget http://reaver-wps.googlecode.com/files/reaver-1.4.tar.gz

Extract the tarball

    tar -xzvf reaver-1.4.tar.gz

Install Required Libraries and Tools

Before you can build Reaver you need pcaplib and later on aircrack-ng (iw) to run Reaver

    sudo apt-get install libpcap-dev sqlite3 libsqlite3-dev libpcap0.8-dev

Compile and Install

Build Reaver

    cd reaver-1.4
    cd src
    ./configure
    make

Install Reaver

    sudo make install

Download aircrack-ng source and build it

Since Ubuntu 12.04 aircrack-ng is not longer in the repository but you can still download it from source and compile it. It’s only one little tweak that need to be done since it will not build without the following errors.

This is how to build aircrack-ng under Ubuntu 12.04

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

Edit common.mak with vi as example

    vi common.mak

Find the following row

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

Remove “-Werror” so that it looks like this

    CFLAGS          ?= -g -W -Wall -O3

Save the file, build and install

    make
    sudo make install

Run

Reaver is now installed and ready to use. You will first need to put the wifi adapter info monitor mode before you can start and the most easiest way is to use airmon-ng (part of aircrack-ng) that you just installed.

First put your adapter info monitor mode, in my case it’s wlan0

    sudo airmon-ng start wlan0

Run Reaver

    sudo reaver -i mon0 -b 00:00:00:00:00:00

Replace MAC 00:00:00:00:00:00 with the actual AP:s MAC address to crack

Wifi and LAN at the same time - force using wifi to access internet

In order to play music from my NAS connected to router I must be connected to the same network. But I want to use wifi to browse internet on faster connection from different network. By default with wifi connected and lan cable simultaneously my elementary os was using lan network for all trafic.

Below command switched it to wifi:

sudo ip route replace default via 192.168.1.1 dev wlan0 proto static

IP 192.168.1.1 is the gateway from wifi network.
