Linux+: Exam Day

I took the Linux+ exam today and passed. The test was pretty much what I expected. It was heavy on BASH commands and file names and locations. If you have about a year of Linux administration experience the test should be pretty easy. Simply using Linux at home would not be enough to prepare you for the exam.


I used the ITExamWorld.com and Sybex practice tests. The ITExamWorld.com test was far superior and there were several questions on the exam that were in the practice test nearly verbatim.

I am overall very happy that I took this exam. I learned a lot in the studying process and while it is not the most prestigious or technical Linux exam out there, the Comptia name carries a level of familiarity with even non-IT professionals that should help in my future endeavors.

openSUSE 11.1 on Virtual PC 2007



There has been a lot of interest in my post about installing openSUSE on Virtual PC 2007 so I decided to post a walk through for openSUSE 11.1. Here it is in all its glory.

What you will need:

  • A PC running Virtual PC 2007 - Virtual PC 2007 is available free from Microsoft here.
  • Either an installation DVD or LiveCD for openSUSE 11.1 - available free here. I use the DVD to keep the actual install time down.
  • Either a DVD writer or some software that lets you mount an ISO file. I use Power ISO - available free here.
I will continue from this point forward assuming that you will be using the install DVD and mounting the ISO to a virtual drive. If you wanted you could burn the ISO to disk and proceed that way with no real difference.

Let's get started:

After downloading all your required software we need to mount the ISO or burn it to disk. I am going to mount it using Power ISO.

Once you have the ISO mounted to a virtual drive you need to setup a virtual machine. Open Virtual PC 2007 and click New.


Click Next

Select Create a virtual machine and click Next


Name your VM and browse for where you want to save it and click next. Note, this is not where the virtual hard drive will be saved so a place like the desktop in fine.

Select Other for the OS and click next.

Chose the amount of RAM for the VM. I went with 1GB for improved performance within the VM but the recommended 128MB would be sufficient. I like to keep this around 1/3 of my total RAM or less.

Select new virtual hard disk and click next.

Select the size and location of the virtual hard disk. I would recommend 5GB for the default load of openSUSE. This will allow you to install all of the common packages and features.

Once you click next you will see a summary of your virtual machine and then click finish. Virtual PC 2k7 will then create your new virtual hard disk and you will now see your VM in the list of machines in the Virtual PC console.

Select your VM and click Start and a new window will open and your VM will begin to boot. Click the CD menu on the VM and select the drive that you mounted your ISO to. Once you have selected the drive the VM should start to load the openSUSE installer. This might take a little while so be patient. Eventually you will see the welcome screen below. Also, in case you are unfamiliar with Virtual PC and having trouble with switch mouse control between the host and guest OS the right ALT key is the default host key. Pressing the host key will allow you to move back to the host OS.


This is where we need to enter our boot options to ensure openSUSE loads properly. Select the Installation option from the menu and a Boot Options field should appear at the bottom of the screen. It this field enter noreplace-paravirt i8042.noloop clock=pit and then press enter.


For a more detailed explanation on what these options do see my other post here. After a moment or two you should see the screen below.


Read the license agreement and click next.

The default selections here are fine. Click next.

Selected your time zone and correct your date and time if needed. Depending on your system you may need to deselect the UTC option but for most machines that is fine.

This is the desktop environment selection screen. GNOME and KDE are the two major Linux desktops. It is a matter of personal preference really but if you have never used Linux before I would suggest GNOME. It is the most Windows like of the two in my opinion. You can also setup a second virtual machine and run both until you find one you like best.

Here you select the file system scheme for your VM. If you have no Linux or UNIX experience I would suggest using a partition based setup for the familiarity to Windows. But I prefer LVM for its flexibility. Here I choose the partition based setup for simplicity and since this would be more familiar for most users.

Enter your name and desired username and password. Unless you are an experienced Linux user I would leave everything else as default. You might also notice that a window will pop up saying something about loading cracker-lib. This is openSUSE checking your password strength. If you use a dictionary word or some other overly easy password it will notify you. I really like this feature, which is in many other Linux distros as well. When you are all done click next. You will be shown an overview of the installation options you have selected and prompted with any issues with the install. Here you can go in and change the default packages that are installed but I would recommend leaving them at default for a new user. And finally...

The install might take a while so be patient. You do have the option of clicking the Details tab and watching the install work. After a little while the install will finish and begin the Automatic Configuration. Once this is done you should see this screen.

Browse the links on this page or click close to start using openSUSE 11.1!

This is a pretty quick and dirty walk through but it should give you all you need to start using openSUSE on Virtual PC 2007. If you have any questions please leave them in the comments and I will do my best to answer them.

New Snake


I just purchased this 08 male het albino possible super salmon boa from Rich and John at salmonboa.com. He looks great in the pics they sent and I can't wait to introduce him to my 04 albino female. They should be shipping him on Tuesday so I will have an update with unpacking pics some time in the middle of next week. I had mentioned in a few posts that I was a little torn on wether or not to try to resume breeding. I finally decided that with the drop in prices in the boa market it was a minimal investment to pick up another male and try again. I actually sold some extra cages I had to pay for this male so there is really no new money going in to it. If this breeding goes well I can recoup most of my initial investment the first season. Even in this poor economy it looks like I can make a few dollars on the side doing something I really enjoy.

News Week Article

News Week has an article up today, link, that talks about all the same issues with multinational corporations I brought up about a week ago in this post.


Makes me feel like a real blogger!

Linux+ : Week 3


I just finished reading through Mike Meyers' Certification Passport Linux+. I really like the Mike Meyers' books. They are easy to read and offer a decent amount of information without getting overwhelming. This is the third book of the series I have read and continues to be a great resource. The books are not for beginners or those looking to really dig deep into the selected topics. They are perfect for users with some experience who are looking to sharpen their skills to pass the given exam.


This book is written by Michael Jang who holds a number of Linux certs including his RHCE, LPIC-2 and of course Linux+. He does a good job covering the basics of RPM based linux distros with attention given to which topics are important for the exam. Since the book was published in 2008 and the last Linux+ exam update was in 2005 there are some topics of interest that will not appear on the test. The author does a good job of balancing these two areas. Because Comptia is neutral within the industry the exam covers no specific distro but the author manages to point out some of the differences between the RPM based versions of linux pertaining to the exam, Red Hat/Fedora, SUSE, Turbolinux and Mandriva.

The true test of the book will come when I take my exam as that is what this book aims to prepare you for. I am getting ready to start the Sybex study guide and some practice exams so we will get an early glimpse at how prepared I actually am. Overall I would say the book is a solid 8/10 for those looking to take the exam. If you are looking to expand your general linux skills or for an introduction to linux I would suggest looking elsewhere. Also, since Ubuntu is by far the most popular linux distribution today I should mention that Ubuntu is not covered in this book, nor is any other Debian based distro. I am no linux whiz but the book has given me a good boost and I think it would be plenty for someone with maybe a year of experience working with linux.

Pop Champagne

This is my new catch phrase.


Examples of use:
Steve: "We are having another baby."
Rob: "Pop Champagne!"

Chad: "I got a raise at work today."
Rob: "Pop Champagne!"

Brad: "Pop Champagne!"
Rob: "Pop Champagne!"

Spread the word.
