Ubuntu is one of those polarising technologies; Its really easy to use on a recreational basis, or as part of a institution/business wide rollout, but heartbreakingly awkward to use ‘alone’ within an entrenched business setting.

Hacking Weekend
So, I’ve been experimenting over the weekend with Backtrack 4. My… Lord….
Times have changed, it used to be that if you wanted to mess with WEP you have to go thru a dozen intermediate stages. wesside-ng makes life so much simpler.30 minutes, fully automated.
What i had done previously was manual airodump-ng, aireplay-ng with arp attacks, and then shifting the caps onto my big box to crack inside of 10 seconds, pity is the packet capture on a quiet network can take a day.
Also, if you cant be assed with the whole Backtrack thing. the whole thing can be swiped from the subversion repo
svn co http://trac.aircrack-ng.org/svn/trunk/ aircrack-ng
Its been a long day.

Primers Coming Up
Thru my work I’m thrown into alot of technologies that i dont nearly know enough about and as with alot of tech related things, the education scene is basic basic basic..GURU with little or no gradiation, so what I’m going to do is post what i learn when i learn it and where i learn it from and hopefully it’ll be useful for someone else, and I’ll also take the opportunity to rehash stuff I’ve already done.
ATM I’ll probably be doing Bash scripting, Perl Scripting, XML, and whatever UNIX stuff comes up whenever I’m writing, but for now and for a relativly simple start; X display fowarding…
This is the setup: Linux/Unix based “client” and “server”; in my case I have headless systems that i fiddle with from time to time, but after a while vim just becomes a pain, and as for viewing html files etcetc copying things back and forth is a pain in the ass.
The solution is already there; From its beginning the X server has always been client server based on some level. Basically what were gonna do is tell the server to use the client as an X display; this is controlled thru an environment variable, strangly called DISPLAY
Lets assume were using SSH. *nix SSHd has a simple system for fowarding and routing the relevent X ports (these wont show up in your “tunnels” tab if your using something like putty, but you shouldnt be using putty anyway)
Theres two versions of this fowarding ability, X and Y. in a nutshell, X is compressed and encrypted. Y isnt. On slow links, Y is probably your best bet, also some servers dont support the X flag. Also also, some sysadms disable this X fowarding.
Anyway, to the point.
login to the server thusly
client# ssh user@server -X
then when you get a shell check to see if DISPLAY isnt already set (some servers are good enough to do this for you)
server# echo $DISPLAY
if your lucky it’ll say localhost:10.0
otherwise it’ll probably say :0.0 or something similar
If your in this unlucky situation, just enter
server# DISPLAY=localhost:10:0
then try it out, by running the clock and forking it into the background (&)
server# xclock &
Job done. Later

Today’s Accomplishments: The 2.0 Generation
As I was walking back from our kitchen in the office, I realised that that ‘lift coffee cup, walk to kitchen, make coffee cup, return to desk’ was the most inefficient part of my working day; I can even justify writing this post as vaguely productive as I’m waiting for a download to complete…
