While your Linux system might not be affected by viruses, there might be some lying dormant in your system. Like when you copied or downloaded files with viruses from another system and then pass the file to another computer whose system (e.g. Microsoft Windows) is vulnerable to viruses. Or if you maintain dual or multiple partitions (e.g. Linux and MS Windows).
Be responsible. Don’t be a carrier.
Using Linux to Disinfect Windows: Yes, you can use Linux to disinfect your MS Windows computer. This is a good “how to” from the Linux Journal outlining the easy steps from downloading to disinfecting your Windows computer without the risk of having even your anti-virus being infected too.
Using Linux to Disinfect Windows

Are you responsible for one or more Windows computers? If yes then the odds are really good that you have had to deal with cleaning viruses and malware. Did you know F-Secure offers a free Rescue CD built on Knoppix for just this purpose? Let’s take a look at how easy the F-Secure Rescue CD is to use.

Some people have been asking me if the posting I did in the past entilted: Setting-up IBM Thinkpad X40 Laptop on Ubuntu Linux to connect to the Internet via 3G/GPRS using Nokia N70 works with newer versions of Linux on other laptops / notebook computers and connected to other mobile phone brands / models.
Yes, it still works with the latest versions of Linux and other laptop computers using different mobile phones. Just to share them to those interested, I will make a listing on what devices it worked and will update this posting once I discover new ones:
Laptop / Notebook Computers:
Mobile Phones:
I tried all of them both on Globe, Smart and when I was in Laos, the local network named Tigo. Nowadays I usually use Ubuntu but I’m sure it will work in other Linux distros as well. Aside from the set up I used in the posting: Setting-up IBM Thinkpad X40 Laptop on Ubuntu Linux to connect to the Internet via 3G/GPRS using Nokia N70, I also tried them using GPRSEC (a graphic user interface dialler) and wvdial (command line dialler). I will write on how to do them on gprsec and wvdial next time. GTG. Cheers!
Several friends have been asking me how I made my wireless device in my MacBook running Ubuntu Linux worked. Others with different brands of laptops have shared also the same problem. I discovered that most of these laptops (MacBook included) have wireless devices with the same Atheros chipsets.
To check if your laptop have Atheros, do:
lspci | grep Wireless
The result:
02:00.0 Network controller: Atheros Communications Inc. AR5418 802.11abgn Wireless PCI Express Adapter (rev 01)
will tell you that you have the Atheros chipsets.
So here’s what you need to do to make your wireless work in Ubuntu:
1. First, make sure you have an alternative Internet connection through your wired ethernet port.
2. For Ubuntu (8.04) Hardy, you just need to install linux-restricted-modules and madwifi-tools packages:
sudo apt-get install linux-restricted-modules madwifi-tools
Prior to Hardy with my laptop installed with Ubuntu (7.10) Gutsy, here’s what I did using Subversion (try this if the first instruction won’t work in Hardy):
- Install Subversion to get the driver source and the needed build tools:
sudo apt-get install build-essential subversion autoconf automake
- Get madwifi using subversion:
svn co http://svn.madwifi.org/madwifi/trunk madwifi
- Compile and install madwifi driver (module name: ath_pci)
cd madwifi
make
sudo make install-modules
The driver is now installed and will be enabled after the next reboot or can be enabled by:
sudo modprobe ath_pci
I was always having difficulty connecting using network manager, so I installed an alternative: wicd.
1. To install wicd you need to add to your repository (append to /etc/apt/sources.list) the line:
“deb http://apt.wicd.net hardy extras”
You can do this by:
echo “deb http://apt.wicd.net hardy extras” >> /etc/apt/sources.list
2. Update your repository:
sudo apt-get update
3. Install wicd:
sudo apt-get install wicd
Note: this will remove your network manager.
You can then run wicd from the menu -> Applications -> Internet.

The Ubuntu desktop CD installer due to limited space contains only what is commonly needed in a desktop. No server packages. So if you try to install a server package, it would really look for an internet connection.
The same way with the Server CD installer. It does not contain everything.
I think they tried to balance the practicality, economy and ease of distributing the software by using only the CD media with a capacity of only 800MB. Given the limited space, they have to prioritized what should be included and have the other software available via the internet.
So, if you’re managing a network with several PCs, there will be times that you will need to update them or need something from the repositories in the Internet — when doing installation and your network connection is also slow or if you don’t have an internet connection at all — a suggestion is to create your own local or personal ubuntu repository. In this way, there is no need for all the PCs to access repositories in the Internet and eventually save on that precious bandwidth.
Then install or update from there using apt. Here’s a good reference/howto to create a personal repository:
https://help.ubuntu.com/community/Repositories/Personal
But of course you have to download the necessary .deb files first and place them in your repository. Next post, a way (work around) how to do this …..
To connect my MacBook to an LCD/Multimedia Projector using a vga to mini-DVI adapter connected to the mini-DVI port, I use xrandr. [for more info do a $man 1 xrandr]
First, you need to check on the available resolutions.
With the other screen/monitor or multimedia projector attached to your MacBook do:
$ xrandr -q
Changing Screen Resolution Problem
After updating from Gutsy (7.10) to Hardy (8.04), I noticed the utility for changing the screen resolution (System -> Preferences -> Screen Resolution) does not work anymore in Hardy as it did in Gutsy. It gave an error message:
The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.
Xrandr Problem
Likewise, when I tried xrandr -q on the command line I got the following X BadRequest error:
$ xrandr -q
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 151 (RANDR)
Minor opcode of failed request: 6 ()
Serial number of failed request: 9
Current serial number in output stream: 9
In my former post: Ubuntu 7.10 (Gutsy) on a Macbook … Part 1, I mentioned:
“I noticed some of the devices/hardware does not work properly on Ubuntu “out-of-the-box” (default install of Ubuntu 7.10 for intel) like sound volume control, iSight, sound recording through the built-in mic. To some of us who are used to doing “right clicks” on the mouse, we need to have an alternative way of doing it given that all Mac laptops only has one built-in “mouse” button that works as a “left button”.
Well, the website:
How to install Ubuntu on a MacBook
[url: https://help.ubuntu.com/community/MacBook] has been useful since following the instructions have made sound (volume control and recording through the built-in mic and iSight (built-in webcam) worked in my MacBook. I also have converted the lower “enter” key to be a “right mouse button.”
While everything continued to work even after upgrading from Gutsy (7.10) to Hardy (8.04), I noticed my lower “enter” key doesn’t worked anymore. So, based from the instruction on the above website, I tried to do again:

To continue from my previous post on the reference site:
How to install Ubuntu on a MacBook
[url: https://help.ubuntu.com/community/MacBook]:
I got the iSight working with additional steps (which the site failed to mentioned). After following the instructions from the abovementioned site on iSight:
a. You need to install isight-firmware-tools.
$sudo apt-get install isight-firmware-tools
b. If you have the isight-firmware-tools already installed you need to do a:
$sudo dpkg-reconfgure isight-firmware-tools
to “point” to the location of the firmware you copied from your MacOS installation/partition.
c. You need to install the module uvcvideo:
- Optional step just to remove any old modules and back up any existing uvcvideo.ko:
$sudo modprobe -r uvcvideo
$sudo mv
/lib/modules/$(uname -r)/kernel/ubuntu/media/usbvideo/uvcvideo.ko
/lib/modules/$(uname -r)/kernel/ubuntu/media/usbvideo/uvcvideo.ko.original
- Update your Ubuntu archive/repository if you haven’t done recently:
$sudo apt-get update
Just got into playing with a Macbook Black from the office last December 2007. Since I’m more comfortable with Ubuntu Linux (than MacOSX Leopard 
), I did a dual boot install using rEFIt [url: http://refit.sourceforge.net/] as a dual (or multiple) boot menu.

I saw a very good reference at the Ubuntu Community Documentation:
How to install Ubuntu on a MacBook
[url: https://help.ubuntu.com/community/MacBook].
The site does not only contains instructions on installing Ubuntu on a Mac but also on making Ubuntu work on the Apple Hardware and some tweaking instructions:
