Ubuntu WPC54g card installation with TKIP Enabled
Finally I got the WPC54g working in my Dell c610 laptop.
My home network has the SSID broadcasting disabled and uses PSK-TKIP security. It was a big pain in the neck to use the open source ndiswrapper and wpa_supplicant. This weekend I stumbled on this little company called Linuxant (hmm.. where are they located?) that provides an easy to use driver loader for a nominant price of $19(US). They allow you to try the software for upto a month. I don't mind paying that for a linux company if it really works and makes my life easier.
Did I make the right decision to go with Linuxant's driver loader. Oh yes, it is a breeze to install the driver. Honestly this is the first time I've experienced a browser based install for a linux software. Here are the steps in brief to install the software. I will add more information if anybody needs.
1. Download linuxant's excellent installation tool.
2. Run the dldrdriverloader.run, it will launch a web browser and will ask for windows driver .ini file and
3. download wpa_package from the link in linuxant's website. For more about wpa_supplicant see here.
4. build it using the dldrwpaconfig tool
5. Use KWifiManager to monitor the signal strength
6. Open /etc/wpa_supplicant.conf file and add the following.
# WPA-PSK/TKIP
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="example wpa-psk network"
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
psk="secret passphrase"
}
7. If needed do /etc/init.d/dldrdriverloader restart
8. Launch KWifiManager to see if the wireless network is connected.
9. You can either use iwconfig/ifconfig or use the network config tool to activate the wlan0 interface.
Your wireless connectivity should be up and running now.
MP3 Player for Fedora
Fedora doesn't come with an MP3 player by default. By the way if u want to play mp3 files right out of the box, then Fedora is not a good option. Try the excellentSimplyMEPIS, an excellent distro based on debian. It comes with every thing required for a desktop system. For those of you with no choice other than Fedora due to various reasons the only way out to is to follow this simple instruction to install a plugin for the Rhythmbox player.

2. Add "Community Maintained (Universe)" version.
3. Added "gcc", make, kernel sources, iptables development libraries,svn,
Install linuxant driver:
1. Download dldrinstall.run file.
2. Run dldrinstall.run file. This will unpack and install the driver. Then it will ask you to launch the brower and point it to the 127.0.0.1:xxxx. Follow the instruction and download the appropriate windows driver (in my case it is wpc54g driver).
3. Buy the linuxant driver for 19.95. Follow the instructions to generate the license key. Input the license key in the webpage. Now your driver is installed.
Install and Configure wpa supplicant:
1. Go to http://www.linuxant.com/driverloader/wlan/full/downloads.php page to download wpa supplicant for debian package.
2. Install the package using "dpkg -i filename" command.
3. Installation will ask you run the command "/usr/sbin/dldrwpaconfig" from root shell. Run it.
4. When it asks the question "Do you want to compile supplicant with OpenSSL support" say "yes".
5. It will ask you "the configuration script supports only wpa-psk" say "yes"
6. It will ask you the wpa preshared key. Supply the pre shared key.
7. Go to the networking tool and activate the wireless interface. (make sure you specify the static IP incase if you use static IP configuration.
8. Now your wireless connection should be up and running.

vnc server configuration
I'm using tightvnc from my client machine (windows xp) to connect to the ubuntu server. However, the tighvnc client didn't display the screen beyond 640x480. So the screen was smaller in the client machine.
Solution: Edited the vnc.conf file in /etc directory to specify $geometry = "1024x960";... now the screen in the tightvnc client is big enough to see most of the window elements in the server. Now I have to figure out how to start vncserver automatically.

Chapter 2: Preparing a New Partition.
Since I used a linux machine with all the drives used up, I didn't want to create a new partition. I followed the hint mentioned in this document.
1. Created a directory /home/lfs for using as the mount directory.
2. Created a mount point directory /mnt/lfs
3. Add the following two lines to .profile file in the root directory.
LFS=/mnt/lfs
mount --bind /home/lfs /mnt/lfs
Chapter 3: Packages and Patches
1.Create a working directory for the downloaded packages and patches with the following command:
#mkdir -v $LFS/sources
2. Make this directory writable and sticky.
#chmod -v a+wt $LFS/sources
