Although some aspects of Ubuntu 11.10 disappointed me, there are still some good ideas among the novelties. And here’s an example with Ubuntu Tour Online, a website written in HTML / Javascript that allows you to quickly test the interface of the distribution. I recommend you try it, it’s pretty stunning.


People who are afraid to install Ubuntu will now be filled to get a first idea, without installing anything on their computer.

The website Online Tour of Ubuntu is available at:
www.ubuntu.com/tour

Note: you can even make inception with, just open the browser and re-enter the address of Ubuntu Online Tour!

I recently found pkgs.org, a nice site can find RPM, Deb, TGZ or TXZ for most major distributions: Archlinux, CentOS, RHEL, Fedora, Debian, Ubuntu, Mandriva, Maegia, OpenSUSE, Slackware …

It includes both the software from the official repositories, but also unofficial sources such as rpmforge, ATrpms, RPM de Remi … Proprietary applications are also available for download (eg Flash, Skype …).

The site is available at:

Aircrack Problem With iwl3945


After upgrading to Ubuntu Maverick, the Aircrack suite stopped working.

After setting airodump to a channel (like usual):

airodump –channel X

It still displayed its status as:

fixed channel mon0: -1

Some forum users advised to use:

airodump –channel X,X

But this didn’t work. For the record, I’m using a Thinkpad X60, with the iwl3945 driver. lshw output:

*-network
description: Wireless interface
product: PRO/Wireless 3945ABG Network Connection
vendor: Intel Corporation

bus info: pci@0000:03:00.0

Luckily, there is an easy to follow thread on the forums which fixes the problem for a similar card. This solution also worked with my 3945ABG.

Here are the commands:

wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-10-16.tar.bz2
tar -jxf compat-wireless-2010-10-16.tar.bz2

wget http://patches.aircrack-ng.org/channel-negative-one-maxim.patch

gedit scripts/update-initramfs
#*** FIND LINE 13: KLIB=/lib/modules/2.6.31-wl/build
#*** REPLACE WITH: KLIB=/lib/modules/$(uname -r)/build
make
sudo make install
sudo make unload
sudo modprobe iwl3945

Alternatively you can also use sudo reboot instead of sudo modprobe if you’re unsure which driver module you need to load.

aircrack should work fine again now. Note that kernel updates might overwrite the module again (and, hopefully, fix the bug at the same time).

The preview version of Windows 8 is available for download. An important change is probably the new interface Metro, adapted for touch screens (really, it is the fashion among Unity, Gnome SHell …). For the occasion, the developers at Microsoft have developed a new BSOD, you know, the blue screen that appears when the system crashes.

Here’s how it looks:

The choice of the bsod is of course a priority in the development phases of Windows.

Today we will see how to block ping responses in Linux.
This trick has no real interest unless you want to hide a little the presence of your machine on a network.
We still keep in mind that the command nmap is able to bypass this trick (eg nmap-sP 127.0.0.1).

To disable response to ping, open a terminal as root and run the following command:

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all

And to go back:

echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all

Warning, these two commands perform the change dynamically and at the next boot, this change is lost.
To make a permanent change, you must edit your /etc/sysctl.conf as follows:

echo “net.ipv4.icmp_echo_ignore_all = 1″ >> /etc/sysctl.conf
sysctl -p /etc/sysctl.conf

We have seen with the release of Fedora 15, the new system is systemd services startup, which will replace sysvinit and Upstart on most Linux distributions. Here are some tips, based on the command systemd-analyze, which can analyze the startup time of your OS.

We start with the time option, which displays the total time you start your system:

$ systemd -analyze time
Startup finished in 6385ms (kernel) + 3228ms (initrd) + 49335ms (userspace) = 58949ms

Here, we start in 59 seconds. It is possible to go further with the option blame, which displays the startup time by service:

$ systemd-analyze blame
12673ms cups.service
11788ms dkms_autoinstaller.service
5264ms network.service
5156ms ip6tables.service
5045ms avahi-daemon.service
…

The analysis result is very interesting, because we know immediately what services that slow start and we can disable them if they do not serve us.
The last option uses the tip pad and provides a graphical start-up time of each service:

$ systemd-analyze plot > plot.svg
$ eog plot.svg

Fabrice Bellard , already known for its various implications in projects such as QEMU, FFMPEG … we just make a PC emulator written in Javascript and runs a Linux based system. The result is quite nice, I tried several commands and they work properly and more: whoami, uptime, top, ps, uname-a, vi hello.c … and even rm-rf /.

The tethering is a technique that allows to share the Internet connection of a mobile device with other devices such as laptops.

You can use your phone as a modem, and this process can natively since version 2.2 of Android. Here’s how to use it:

How to know which version of its Android phone?

To find the version of Android on your phone, go through the menus:
Settings → About this phone → Information → Android Software Version

If you have a version lower than 2.2, the tethering will not be available. Then consider updating your device.

Enable tethering on your Android phone

To enable tethering on your Android phone:

• Go to the menu “Settings” -> “Wireless & Networks”
• Then “Settings Access Point Wi-Fi”: choose a router name and password
• Then activate the “access point Wi-Fi laptop”

• Turn the 3G network as you normally do
• Open a browser on your Android and test the Internet connection is working properly

On your computer

• Connect to Wi-Fi, whose name is one that you choose

Please note, in some telephone operators (Orange, Vodafone, DigiMobil…), a connection filtering was implemented to prevent you from using your 3G connection with your desktop computer. So when you open an Internet browser, one page offers you to subscribe to a paid subscription.

To circumvent this, there is a technique: changes the User Agent of your browser.

With less than Firefox 4.0, just:

• return address about: config
• accept the warning message
• enter “useragent” in the search filter
• general.useragent.extra.firefox change the key by putting a zero value for example

For Firefox 4.0 and higher, just:

• return address about: config
• accept the warning message
• Right click in the white area → New → String of characters
• Then added the key general.useragent.override with the value that is desired

The final version of Gnome 3.0 was released a few days ago. This was much awaited as it brings many changes in organization of work. Indeed, with Gnome 3.0, everything revolves around the notion of activity rather than virtual desktops. The user starts well in one or more activities (eg Internet, music, office …) and can then switch between them, thanks to the Windows key on the keyboard for example.

Gnome 3.0 developers are hopping to get a head start on the competition by offering users a modern working environment and efficient.

More generally, here are the main changes in Gnome 3.0:

• a new desktop interface.
• a new interface for the file manager.
• messaging is completely integrated into the desktop. The instant messages appear as pop-ups at the bottom of the screen. You may reply directly.
• a notification system that records alerts until the user reads them.
• a new way to create workspaces is available (see video).
• all features are accessible from the keyboard.
• icons can’t be added to desktop.
• windows cannot be resized easely.

If you want to test Gnome 3.0 now, you can use one of two LiveCDs available on the official website (version OpenSUSE or Fedora). ISOs do not work very well with VirtualBox (graphics driver problem).

You can also install Gnome 3.0 on Ubuntu 11.04, using the following command lines:

sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update && sudo apt-get install gnome3-session

Warning, this PPA is experimental and is not compatible with Unity.
