It’s not that easy to get PPP over WLAN running in Ubuntu.
Network Manager lacks the option to choose a connection, but instead always tries to connect through ethernet. This works fine when you are actually plugged to a wall, but sometimes you connect to a LAN over WLAN and then need to establish a PPP connection to the internet.

Instructions on how to set up an Ubuntu cluster can be found at https://help.ubuntu.com/community/MpichCluster .
I’ve updated a few outdated commands there myself so it shouldn’t be too hard to follow the instructions. The only thing I personally did differently was that I didn’t create a new user, but instead used my old account on all the machines (the important thing is that the username be the same everywhere).
In this post I’ll explain how to make a Python script to utilize this cluster using the MPI standard for parallel programming.
To prepare your Python interpreter for parallel programming, you first need some sort of an MPI interface. Several exist so it’s up to you to choose. I used mpi4py. This is part of the scipy module and it can be installed through Synaptic or with:
sudo apt-get install python-dev # other potential packages to consider - python-mpi mpichpython python-scipy python-numpy

To get started with LaTex quickly I googled a bit and quickly found a cross-platform editor I am very happy with – TexMaker.
You can install it by issuing:
sudo apt-get install texmaker
The interface is very intuitive. Among the editor’s features are code completion, spell-checker (although I didn’t succed at configuring it), wizards with document templates… You can find the user manual and a decent LaTex reference under Help. You can see what it looks like in this screenshot:

You need the following packages installed:
(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.).
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):
