DataBook® for OS/2 Returns – in part

Thanks to WD “Bill” Loughman of Berkeley, California for sending me his downloads of some of the pages of the original DataBook for OS/2. Using that data, I have recreated the pages that he has saved. This is a great boon for anyone still using OS/2.

Unfortunately, much more data is still missing. If you, by any chance, have downloaded and saved any pages from the DataBook for OS/2, I would be very appreciative if you would zip them up and send them to me.

Not many people use OS/2 any more, but a bank I worked for recently just retired their last OS/2 ATM a few months ago. So it is still around.

Next “Theory and Practice of Linux System Administration” Class Starts Feb. 13

The next session of my class, “Theory and Practice of Linux System Administration” will be run February 13 through 17, 1012.

Taken from my own experiences accumulated during more than 14 years of using Linux, and developed using my knowledge and experience as a course developer and trainer for both IBM and Red Hat, this class covers the practical aspects of Linux System Administration. It builds upon the foundation of the “Philosophy of Linux” in a way that helps the student understand how and why things are done as they are.

Our courses are always highly rated and well reviewed. Here are some comments from previous students taken directly from the course evaluation forms.

Seats Available

There are still seats available for my Theory and Practice of Linux System Administration class which starts on Monday, January 23 and runs for five days.

Course Description

The student will learn about the history of Linux and the philosophy of Linux and how it applies to the everyday tasks that she will be expected to perform. The student will install a current Fedora Linux system on common Intel hardware, using various installation options to customize the final result. The students will learn to use the command line interface (CLI) and many basic Linux commands along with the vi editor. More advanced commands such as sed and awk will be covered and combining all of these commands into short command line programs will be discussed and the student will have opportunity to use them in lab projects.

This course covers the Linux boot sequence and the traditional SystemV init scripts as well as an introduction to the new systemd daemon for startup and daemon management. The student will learn to manage users and software packages. Networking, security, processes, filesystems and Logical Volume Management will be covered in detail.

Schedule

Please check the Training page for complete class schedules and seat availability. Please contact us to sign up for classes as soon as possible. Our classroom facilities are very limited so class sizes are very small.

Theme Change

As you can probably see, if you have been here before, I have made a major change in the look and feel of the DataBook web site. I have changed to a new WordPress theme and have made some minor customizations of that new theme.

You may even notice changes when you move from page to page. That is just me making a few tweaks to the theme.

I really like WordPress, which is the Free Open Source Software (FOSS)  I use for all of my web sites, because I can change the look and feel—the theme—with a couple clicks of a mouse.

I hope you like the new theme, and appreciate your patience if things do not quite work right. Please let me know via the Contact page if you notice a problem.

SOPA Protest

This website will participate tomorrow, January 18, 2012, in protest of the SOPA law. That law would restrict the Internet freedoms of everyone for the somewhat questionable  financial benefit of a few media companies. In order to restrict alleged piracy, they would restrict the entire Internet. Web sites could be closed without any warning or even proof that they were in violation of any law—except the laws of greed.

Read about SOPA and the protest.

This bill will break the Internet as we know it.

Now Forming: Linux Administration Class

I am in the process of forming a class roster to test a new Linux Administration course I am creating. This 5-day class will be held in Raleigh, NC, July 25 through 29. The normal cost for this course would be $1995 per student, but because this is a test class, there will be an $800 discount for a cost of $1195 per student. This is a one time offer. All future classes will be at the full rate. To obtain this discounted rate you must be enrolled and course fees paid no later than 5:00 PM on July 15, 2011.

I have a couple students committed to this class and would like to have a few more.

This class is based upon material I have put together over several years for a number of different specialized reasons. I am in the process of filling out the areas needed to cover all aspects of an Introduction to Linux  System Administration.

Course Synopsis

This course is intended for  junior Linux Systems Administrators who wish to advance their knowledge, and administrators of other Unix versions or Windows who wish to become Linux System Administrators. This class is heavily oriented towards hands-on activities. At least half of the class time is allotted to lab projects. The class is based on Fedora because it is the upstream distribution for Red Hat Linux.

The student will learn about the history of Linux and the philosophy of Linux and how it applies to the everyday tasks that she will be expected to perform. The student will install a current Fedora Linux system on common Intel hardware, using various installation options to customize the final result. The students will learn to use the command line interface (CLI) and many basic Linux commands along with the vi editor. More advanced commands such as sed and awk will be covered and combining all of these commands into short command line programs will be discussed and the student will have opportunity to use them in lab projects.

This course covers the Linux boot sequence and the traditional SystemV init scripts as well as the new systemd daemon for startup and daemon management. The student will learn to manage users and software packages. Networking, security, processes, filesystems and Logical Volume Management will be covered in detail.

The course outline (subject to change) is shown below:

  • Introduction To Linux
  • The Linux Way
  • Installation
  • Getting logged in
  • Using the Console
  • The Command Line Interface (CLI)
  • Basic Linux Commands

Fedora 15 on the Horizon

Fedora 15 is in Beta testing now and will be available—barring unforeseen complications—by the end of May. There are some interesting new features including desktops GNOME 3 and KDE 4.6.

The feature that will probably make the most difference to Linux Administrators and almost none to end users is the new systemd daemon. This “System Daemon” will replace the SystemV Init scripts which have been around forever; it also replaces the much newer Upstart which has barely gotten a toehold.

Fedora, being the sometimes bleeding edge distribution that it is, Fedora 15 will be the first distribution to include systemd.

The primary purpose of systemd is to launch and manage other needed daemons and processes, but it does it much more intelligently by only starting them as they are needed. Thus much of the systemd function can replace that of the Internet Superdaemon, xinetd or inetd, depending upon your distribution. The xinetd daemon simply hangs around waiting for an Internet connection attempt on one of its supported servers such as Telnet. It then starts the appropriate server and passes off the connection to that server and then waits for another connection attempt.

The systemd works much the same way, only not just with network-based services. It works together with UDEV and D-Bus to determine when a local daemon is needed and then starts it. Starting local daemons only when required saves system resources and can significantly improve boot time. This improved boot time is the only thing that most users will notice.

For a little closer look at Fedora 15 see 7.5 Reasons to Look Forward to Fedora 15 at Linux.com.

For all of the gory details of systemd, see http://0pointer.de/blog/projects/systemd.html. This German web site also has an excellent multipart series, systemd for Administrators.

Fedora Frog 2.0-14.0.0 Released

I have released version 2.0-14.0.0 of Fedora Frog.

This interactive, text mode, menu-driven Bash program provides the Linux administrator an easy way to install applications not installed by default during a Fedora Core installation procedure, and applications that are not part of the standard distribution. Additional repositories are required beyond the normal Fedora ones, and they are automatically added by Fedora Frog as well.

Frog installs media players such as RealPlayer, Mplayer, VLC, Kaffiene and Xine. It also installs Thunderbird, Firefox, GNUCash, Adobe Reader and Yumex, and some things specifically for System Admins such as chkrootkit, iotop and more.

Fedora Frog currently supports Fedora 10, 11, 12, 13 and 14. Support for all previous versions of Fedora has been removed.

New features in this release include:

  • Added support for Oracle VirtualBox-4.0 with extensions and keep support for VirtualBox 3.2 which is still available.
    Set this up for selection in a new Radio Button menu due to choice complexities.
  • Added the screen program.
  • Added support for Fedora 13 and 14.
  • Resolved minor issues with VirtualBox.
  • Added nVidia PAE support.
  • Added more Admin programs such as ntop, powertop, iptraf, etc.

Fedora Frog is distributed under the GPL2 license. Fedora Frog can be downloaded from SourceForge at https://sourceforge.net/projects/fedorafrog/.

Working on Fedora Frog 2.0-14

If you are waiting for the next version of Fedora Frog I am testing the latest code right now. It should be ready in a few days.

This version of Fedora frog will support Fedora 10 through 14.

This interactive, text mode, menu-driven Bash program provides the Linux administrator an easy way to install applications not installed by default during a standard Fedora installation procedure, and applications that are not part of the standard distribution.

Frog installs media players such as RealPlayer, Mplayer, VLC, Kaffiene and Xine. It also installs Thunderbird, Firefox, GNUCash, Adobe Reader and Yumex, and some things specifically for System Admins such as chkrootkit, iotop, powertop and others.

As always, this latest version of Fedora Frog will be available on SourceForge.

Page Sequence Problems

There are currently some problems with the way in which WordPress displays pages in the order I specify. As a result many pages do not appear in the order in which I would like them to appear.

This is not about the posts, of which this is one, but about the pages that appear in the Table Of Contents section in the right-hand column.

Please be patient as I try to get this problem resolved.
