Installing aircrack-ng from subversion

I recently made a commit into aircrack-ng subversion repository adding an environment variable ready to build “external” scripts like airoscript-ng, airgraph-ng, versuck-ng and airdrop-ng, as well as any other directory inside scripts/ dir wich contains a Makefile.

This has two implications:

• It’s quite easy to do a package from that (I’m working on an unofficial weekly subversion package)
• It’s quite easy to install aircrack-ng with sqlite support, all the unstable stuff and the plugins

I’ll explain how to do the last one, in a few single script:

apt-get install subversion build-essential libpcap0.8 libssl1.0.0 zlib1g wireless-tools xterm python graphviz macchanger dsniff hydra zenity pyrit sslstrip wkhtmltopdf john libpcap0.8-dev libssl-dev libsqlite3-dev libnl-dev
svn co http://trac.aircrack-ng.org/trunk/
make -C trunk unstable=true ext_scripts=true sqlite=true
make -C trunk install unstable=true ext_scripts=true sqlite=true

Et voilá, you execute that as root, it will get lastest aircrack-ng revision and dependences (and most of airoscript-ng ones, all the necesary and packaged).

Bringing back old flash /tmp files!

I recently wrote a script for playing files on recent browsers with mplayer, a friend asked me if could bring the old system back… so here I did it, each time you execute this script you’ll have your current playing videos linked again in /tmp with their old names:

for i in $(pgrep -f flash); do file /proc/$i/fd/*|awk '/Flash/{ gsub(/`/, ""); gsub(/:/, ""); system("ln -s " $1 " " $6); }'; done

Playing temporary files with mplayer on Flash 11

Back in the times of Flash Player 10 we could do an mplayer /tmp/Flash*. You could use mplayer on your flash videos, or even download them! Sadly, Adobe realized that, and fixed it.

But it’s still posible! Basically, each process has a list in /proc of all the File Descriptors it has opened, between them we’ll find our flv file.
More concisely, It will reside on /proc/_PID_/fd where PID is the process id, and will be a symbolic link, pointing to /tmp/FlashXXX
You’ve read right, points to /tmp/FlashXXX as the old ones, so we can just list it and filter by that name

Save or play your youtube, megavideo, daylimotion and many more flash videos on linux!

I first tried listing all files in /proc/*/fd but that was slow as hell, so I filtered out (thanks to pgrep) the ones matching all full processes containing “flash” (should work on firefox and chrome at least) in their full call.

for i in $(pgrep -f flash); do file /proc/$i/fd/*|awk '/tmp\/Flash/ { gsub(/:/, ""); print $1 }'; done

You can now just use that files with mplayer!

I, personally, have buggy speakers and use it for manually increasing the volume output with softvol switch (forcing a software volume mixing)

mplayer -fs -zoom -idx -softvol -softvol-max 10000 -volume 5000 `for i in $(pgrep -f flash); do file /proc/$i/fd/*|awk '/tmp\/Flash/ { gsub(/:/, ""); print $1 }'; done`

Vim workshop at downgrade hackerspace.

This evening in zaragoza we were assisting at the VIM Workshop organished by the downgrade hackerspace. I was (supposedly) one of the speackers, even tough I didn’t have in mind any kind of speech. I planned it as a de-centralized workshop, but people seemed to not understand that.

Thanks god that meskio was there, to use his social habilities to get things started. It ended up being a producitve workshop, were all of us gained some vim knowledge. I learned some curious tricks, and the vim local_vimrc plugin, wich allows you to have nested vimrc files.

After all this workshop installing and messing with plugins and pathogen, I came up with yet another vim configuration starter, wich you can find here. This script will (remember to clean your env first) install pathogen, configure it and install nerdtree, conqueshell and VimBlog in bundles dir.

It’s basically a five-liner, wich will end up with a pathogen-enabled .vim directory and a few useful plugins, wich can be configured:

plugins=( "The-NERD-tree" "Conque-Shell" "vimblog.vim" )
wget -nd -P .vim/autoload https://github.com/vim-scripts/pathogen.vim/raw/master/plugin/pathogen.vim
wget http://lh-vim.googlecode.com/svn/misc/trunk/plugin/local_vimrc.vim -nd -P .vim/bundle/local_vimrc/plugin/
grep 'call pathogen#infect()' ~/.vimrc || { echo -e "\ncall pathogen#infect()\nlet g:local_vimrc=".vimrc"\n" >> ~/.vimrc; }
cd .vim/bundle && for i in ${plugins[@]}; do git clone https://github.com/vim-scripts/$i; done

Managing android virtual machines the CLI way

In a previous post, I were explaining how to generate android packages using a script I made.

I’ve recently upgraded that script so that we don’t have to create any virtual machines, if there is not a virtual machine with the name of the pacakge we’re doing, It’ll automagically create one!

It’s basically using “android” tool from android sdk, with the avd parameters, wich are:

• list avd : Lists existing Android Virtual Devices.
• create avd: Creates a new Android Virtual Device.
• move avd: Moves or renames an Android Virtual Device.
• delete avd: Deletes an Android Virtual Device.
• update avd: Updates an Android Virtual Device to match the folders
