How To Upgrade Ubuntu 9.10 to Sabili 9.10

0 comments

If you have an old version of Ubuntu, less than 9.10, you should first upgrade your system:

sudo aptitude update && sudo aptitude safe-upgrade

sudo aptitude dist-upgrade

Then, to convert Ubuntu to Sabily, follow these steps:

Open a terminal window (Applications→Accessories→Terminal), and execute the following command:
sudo wget http://www.sabily.org/sources.list.d/`lsb_release -cs`.list --output-document=/etc/apt/sources.list.d/sabily.list; sudo apt-get -q update; sudo apt-get --yes -q --allow-unauthenticated install sabily-keyring; sudo apt-get -q update



Then install the sabily package:


sudo aptitude install sabily



Answer ‘Yes’ when needed.
If you want to install the optional package WebStrict (Web Content Filtering tool), just run the following command:

sudo aptitude install webstrict




Finally, restart your computer to apply changes.

To Do List After installing Ubuntu 9.10 aka Karmic Koala

0 comments

Yup it’s this time again, another awesome Ubuntu release from Canonical. But hands down, it’s the best Ubuntu release yet. The gifts as you probably have known as of now includes impressive installer, fast boot times, new artwork (new bootscreen, themes, wallpapers and icons) , more cloud integration, home directory encryption and…countless many more. As you would expect from any upgrade, the packages are a bit different, so this to do list will be a bit different from the previous ones :


1 – Expand the Software Repository List


First of all, lets make Ubuntu “see” more packages. Go to the terminal and edit your sources.list with :

sudo gedit /etc/apt/sources.list


Here is the content of my sources.list which I think is quite complete to have all the necessary applications you could ever need. So delete the whole content of your sources list and replace it with the content of mine

Save it. Now import the necessary repositories keys to avoid “apt-get” crying about some missing keys, go to the terminal and type:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2EBC26B60C5A2783 0DA7581859566E92 D739676F7613768D 43BB102C405A15CB 6AF0E1940624A220 2ED6BB6042C24D89 632D16BB0C713DA6 A6DCF7707EBC211F F9A2F76A9D1A0061 5A9BF3BB4E5E17B5 A040830F7FAC5991 FA3A1271 7FB8BEE0A1F196A8 0CC1223EE2314809 7889D725DA6DEEAA 28A8205077558DD0 2D79F61BE8D31A30 6E871C4A881574DE 66D5C734F6EFB904 DCF9F87B6DFBCBAE 2A8E3034D018A4CE F0876AC9 978228591BD3A65C 6298AD34413576CB FC6D7D9D009ED615 4FEC45DD06899068 2A423FD95416E75D

Linux comes with such many services and daemons.
If you confuse -just like me- about services / daemons in linux world, here are list some services / daemons that common use by default by Linux system.

* ConsoleKit
The ConsoleKit maintains a list of sessions and therefore is useful if you use Fast User Switching. If you use gdm and Gnome leave this enabled.

NetworkManager provides automatic network detection and configuration for the system. It is useful for modern laptops, where the user may move between wireless networks, and plug in to a variety of wired networks. Unless you are such a user disable it.

* anacron
Anacron can be used to execute commands periodically. Unlike cron, it does not assume that the machine is running continuously. Hence, it can be used on machines that aren’t running 24 hours a day, to control daily, weekly, and monthly jobs that are usually controlled by cron. Leave it enabled.

* atd
atd runs jobs queued for later execution.

* auditd
auditd starts the Linux Auditing System Daemon. Leave it enabled especially if you are using SELinux.

Novell - On the way to becoming a Linux business?

0 comments

Novell's recently released figures for the second quarter of 2009 showed an 8.5 per cent drop in sales compared to the previous year – not a big surprise in light of the much debated economic crisis. Even so, the latest figures are in line with the broad trend at Novell. Sales have been falling for years – from just shy of $300 million per quarter in late 2004 to around $216 million now. However, one area of the business has enjoyed constant, indeed double-digit, growth over the last few years – Linux. Three years ago, sales from the Linux business were around $10 million; this year they have already hit $37 million .
