Out of the box Ubuntu 9.10 wireless/wifi did not work on my Sony Vaio CW Series (VPCCW26FG), The following error message is shown on start up and on dmesg command.

Could not read microcode: -2

The solution was to install backports modules.

Installing Wireless Drivers on Ubuntu

sudo apt-get clean
sudo apt-get update
sudo apt-get install linux-backports-modules-karmic

In order to automate rsync without any password or transports, we need to setup the rsync daemon on one of the server. Suppose we want to sync data from a slave server to a live server.

Configuring the Slave Server

In the slave server we have to run the rsync daemon which accepts connections from live. Inorder to do this, we have to first edit the

/etc/rsyncd.conf

Add an entry in

/etc/rsyncd.conf

with the following template

[Module_Name]
        path = Filesystem_Path
        comment = Comment

Ubuntu 9.10 ships with the new GRUB (Grand Unified Boot Loader 1.97 beta) in plain words its the software that boots the operating system you choose when you boot the computer. In earlier versions of Ubuntu / Grub to change the menu on the grub screen, one had to edit the /boot/grub/menu.lst file. In the new system this a little different from just editing the one file.

The GRUB configuration now resides at /boot/grub/menu.cfg But do not edit this file as it is generated from files from /etc/grub.d/* and /etc/default/grub.
