Here is the solution (at your own risk).


$ sudo apt-get install linux-headers-$(uname -r)
$ wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-12-20.tar.bz2
$ tar -jxf compat-wireless-2010-12-20.tar.bz2
$ cd compat-wireless-2010-12-20
$ wget http://patches.aircrack-ng.org/channel-negative-one-maxim.patch
$ sudo apt-get install patch
$ patch ./net/wireless/chan.c channel-negative-one-maxim.patch
$ make
$ sudo make install
$ sudo make unload
$ sudo reboot


For Windows and Linux versions, check out these custom extension builds from Gears Google Group. If you are Mac OS X users you can get it on Google Code.

I’ve tested the Mac version, so far everthing’s working as expected. I believe official builds by Google will be coming very soon if you’re happy to wait.

If you would like to read & write to your ntfs partition (windows’s partition), installing ntfs-3g on your machine is a better solution. This is the method I used to install ntfs-3g on my debian etch :

1. Remove old libfuse (if any) :

sudo apt-get remove libfuse2 fuse-utils

2. Get required package:

wget http://snapshot.debian.net/archive/2007/04/10/debian/pool/main/n/ntfs-3g/ntfs-3g_1.328-2_i386.deb
wget http://snapshot.debian.net/archive/2007/04/10/debian/pool/main/n/ntfs-3g/libntfs-3g0_1.328-2_i386.deb
wget http://snapshot.debian.net/archive/2007/04/10/debian/pool/main/f/fuse/libfuse2_2.6.3-2_i386.deb
wget http://snapshot.debian.net/archive/2007/04/10/debian/pool/main/f/fuse/fuse-utils_2.6.3-2_i386.deb

3. Install it!

dpkg -i libfuse2_2.6.3-2_i386.deb fuse-utils_2.6.3-2_i386.deb libntfs-3g0_1.328-2_i386.deb
dpkg -i ntfs-3g_1.328-2_i386.deb

Let me know if it doesn’t work for you. Now, you can mount your ntfs partition. This is an example how I do it:

sudo mount /dev/sda1 /media/usb -t ntfs-3g

I have been using Eclipse for quite some time now. I prefer Eclipse as development IDE because its ease of use. The overall design of Eclipse keeps the tools you need immediately at your fingertips.

Using APT to install Eclipse on your Debian / Ubuntu machine will give you the old version of Eclipse. I would like to share with you my steps to install Eclipse 3.3 manually.

1. You’ll need JRE installed on your machine.

sudo apt-get install sun-java5-jre

2. Download Eclipse SDK from its main site (Choose Eclipse Classic) :

http://www.eclipse.org/downloads/

3. Extract the eclipse download and move to opt.

tar xzf wtp-all-in-one-sdk-1.0-linux-gtk.tar.gz
sudo mv eclipse /opt/eclipse cd /opt sudo chown -R root:root eclipse
sudo chmod -R +r eclipse
sudo chmod +x `sudo find eclipse -type d`

4. Then create an eclipse executable

sudo touch /usr/bin/eclipse
sudo chmod 755 /usr/bin/eclipse

5. Create the file

sudoedit /usr/bin/eclipse

With the content:

#!/bin/sh
#export MOZILLA_FIVE_HOME=”/usr/lib/mozilla/”
export ECLIPSE_HOME=”/opt/eclipse”

$ECLIPSE_HOME/eclipse $*

6. If you use gnome, create a shortcut

sudoedit /usr/share/applications/eclipse.desktop

With the content :

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse IDE
Exec=eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=GNOME;Application;Development;
StartupNotify=true
Configure

That’s it. You can start your eclipse by typing eclipse in your terminal. The new Eclipse a bit faster than before. You should have a try.

Qemu -smb option does not work on Debian/Ubuntu because of a bug in Samba package. Rebuild the Samba package without the –with-fhs option to work around it. But you still can use samba without “-smb” option. Lets say you have ubuntu as host OS and WindowsXP guest OS.

Install samba server on host OS :

sudo apt-get install samba smbfs

Then make a folder :

mkdir /home/smd/public_share
chmod 777 /home/smd/public_share
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
sudo nano /etc/samba/smb.conf

Find this line :

...
; security = user
...

Replace with :

security = share

Insert the following lines at the end of file :

[public]
comment = Public Folder
path = /home/smd/public_share
public = yes
writable = no
create mask = 0777
directory mask = 0777
force user = nobody
force group = nogroup

save the edited file. then,

sudo testparm
sudo /etc/init.d/samba restart

Now, you can run your guest OS.

qemu -hda winxp.img -localtime -kernel-kqemu -m 384 -boot c

Open your shared folder :

Start Menu -> Run -> \\10.0.2.4\

By default, 10.0.2.4 = host ip and 10.0.2.2 = guest ip.

If you’re still running kernel 2.4.x, to burn a cd you’re forced to use SCSI emulation (under kernel module ide-scsi). But in kernel 2.6.x, it’s easy as 123. We can use ide-cd.

Firstly, you’ll need to load it:

sudo modprobe ide-cd

And to burn a cd, you have to make an iso file. Use apt and get the mkisofs package.

sudo apt-get install mkisofs
sudo apt-get install cdrecord

Make your *.iso file :

mkisofs -o test.iso /home/smd/testfolder/

and burn the *.iso file using cdrecord :

cdrecord dev=/dev/cdrw /home/smd/test.iso

Ok. Thats it. This is just a basic usage. Details? google it.

Many distributions of Linux have an option to install MySQL. In this case, or even if you compile MySQL, the default password is blank.

Make sure that you set password for the root user. This is the command:

mysql -u root mysql
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('s3cr3tp4s5w0rd');

ERROR: QEMU requires SDL or Cocoa for graphical output
To build QEMU without graphical output configure with –disable-gfx-check
Note that this will disable all output from the virtual graphics card.

While compiling I got the following errors. To solve this problem, I’ve to install SDL library.

sudo apt-get install libsdl-dev

Should works with Ubuntu or any Debian-based distro.

While connecting to GoogleTalk/MSN, if you see this message:

Server require TLS/SSL for this connection

That’s mean you did not compile Pidgin with SSL support. All you have to do is to install required ssl.

sudo apt-get install libssl-dev libnss3-dev

Recompile and all done! Have a try.

Debian change Firefox to Iceweasel. Since Google’s toolbar does not install as the installer does not recognize Iceweasel as Firefox. To get full Google Toolbar support:

1. in the navigation: about: config
2. filter for : general.useragent.extra.firefox
3. change Iceweasel/2.0.0.4 To Firefox/2.0.0.4

Go back to Google Toolbar’s website, and install.
