WEP cracking

You need the following packages installed:

aircrack-ng

(from Synaptic or from terminal “sudo apt-get install aricrack-ng”)

Next I will give you the terminal commands – you just have to change the parts so that they reflect your situation (for example mac addresses, interfaces etc.).

The recipe

Start airmon on your wireless interface (“ip -d addr” might help if you’re not sure):

airmon-ng start wlan0

Monitoring traffic (enter number from 0 on instead of – sometimes you’ll have to backtrack here to change the channel):

Num pad doesn’t work in Ubuntu

When I installed Ubuntu 9.10, my num pad stopped working as it used to – it moved the mouse instead of inputing numbers. Pressing num lock didn’t help either.

Anyway I found the solution quickly on Ubuntu forums:

It appears it’s some accessibility feature. I probably pressed some key combo that turned it on.

Syncronizing your usb and hard disk with Unison

Today I decided to automate the tedious process of syncronising my SD card and hard drive (for example to get files to an e-book reader faster and be able to read from it more often (which is way better than straining your eyes reading from a monitor)). The good thing is that you can later use the same technique to sync USBs, external hard drives, even remote machines via ssh or ftp – you just tweak the paths.

First I thought of Linux’ rsync command, but Unison is suggested as a bit more user-friendly and abstract program that achieves the deed. Here’s how you do it.

Dynamic web page construction in Ubuntu – Part 1: installing a LAMP server

Introduction

In this topic (which will span through several posts) I will share my experiences in creating a dynamic web page on the example of www.epska.org, the site I am currently building on my own from scratch (unlike this blog, which is done using the Drupal CMS). It is dynamic on several levels: 

1. content is separated from design using a .css file
2. navigation menu, header and footer are separated from the content of the page by using the php include function.
3. content is dynamically extracted from a MySQL database

The business

In this first part, we will install and set up a working localhost server – for debugging or (in case you have your own server) actual hosting of the web site.

How to set up an OJÄB VPN connection in Ubuntu GNU/Linux

1. Required packages

You’re gonna need “network-manager-pptp” package installed.
If you can connect to the Internet somewhere else (like in a Coffee
bar or sth) open Synaptic package manager, search for and install the
“network-manager-pptp” package (or enter “sudo apt-get install
network-manager-pptp” from a terminal).

If you don’t have Internet available anywhere you can also find
this package on the Ubuntu install CD if my memory is good (somewhere
buried in the folders).
