Broadcom Wireless STA driver fix for Ubuntu

Found a Broadcom wifi card facing problems after 2.6.31-20-generic-pae kernel upgrade on Ubuntu 10.04 (Dell Inspiron with a i3 processor)

Trying to activate the driver via the System -> Administration -> Hardware Drivers -> enable the Broadcom STA proprietary wireless driver route failed with an error in /var/log/jockey.log

WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl
WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver

Resolution:
To resolve this, wl module needs to be inserted into the kernel. Easiest way is to get the latest kernel installed which comes along with this module (Just to avoid all compilation headache)

So, go ahead and get the latest version of kernel installed (ex: 2.6.32-23-generic) along with the kernel headers
Packages: linux-headers-2.6.32-23, linux-image-2.6.32-23

Run modprobe for wl as follows:

modprobe wl

Now try activating the Broadcom device, it should work just fine.

Enjoy!

Dell OpenManage, Citrix XEN and iptables

To get your OpenManage installation working on a DELL Server installed with Citrix XEN Server, add following IPTABLES rules:

INPUT Table
-A INPUT -p tcp -m tcp –dport 5666 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 1311 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 5666 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m state –state NEW -m tcp –dport 1311 -j ACCEPT

OUTPUT Table
-A OUTPUT -p tcp -m tcp –dport 5666 -j ACCEPT
-A OUTPUT -p tcp -m tcp –dport 1311 -j ACCEPT
-A OUTPUT -p tcp -m tcp –dport 5666 -j ACCEPT

Put these rules in /etc/sysconfig/iptables file or execute each line through command line and then save the rules.

Installing Debian Lenny VM on Citrix XEN

If you’re trying to install Debian Lenny on a XEN VM you might end up with the following error no matter which debian repository you use to install.

can’t download file (/dists/lenny/main/installer-i386/20090123lenny1/images/netboot/xen/vmlinuz)

Resolution:

Smiplest way to install lenny on xenserver5.5 is
"install from URL:http://mirrors.cn99.com/debian/".

The above URL works perfectly on Citrix XENSERVER 5.5.

Otherwise you will have to install it using the ISO provided in the follwing URL

WordPress 3.0 “Thelonious” – Upgraded

Upgraded to latest version of WordPress release “Thelonious“. Lots of new features. Mu integrated as well. Wow!

Liked auto upgrade and many other features integrated in new release. Optimizing wordpress with Super-Cache really helps. I’m yet to find a way to make my site run off suphp so that there won’t be any memory overhead. Lots to research but little time ;)

Bonus

If you’ve made it this far, check out my 2010 State of the Word speech at WordCamp San Francisco, it’s jam-packed with information on the growth of WordPress, 3.0, what we’re planning for the future, and the philosophy of WordPress.

GIMPFx for quick Image editing

There is very little time to process the images that I click through my digital camera. Even if you like to send out couple of pics to friends, it becomes hard to send them without editing. I have found a way to quickly process the images, add borders etc through GIMP easily.

GIMPFX-Foundry project found while googling about GIMP scripts makes it so simple to perform lots of Image post processing operations like a pro.

Download the zip or tarball from the project page, untar it to /home/<username>/.gimp-<version>/scripts folder and start GIMP. You will find a new menu item called “FX-Foundry” as shown above. Click on it to find more than 90 scripts to play with your Images.

Btw, searching for GIMP tutorials? Check the following links:
