KLUG Weekly Meeting Notes

Tuesday, June 28, 2005



Presented by Dirk Bartley

Watch for the posting of this presentation:

Dirk used the LTSP workstation and the KLUG SVGA projector to display
his slides with OpenOffice.org Impress. He presented two SAMBA file
management implementations. The first was Microsoft’s DFS that allows
file shares on Windows workstations. The second was Rsync that allows
you to back up one machine’s files to another machine.


Distributed File System (DFS) allows administrators to group shared folders
located on different servers by transparently connecting them to one or more
DFS namespaces. A DFS namespace is a virtual view of shared folders in an
organization. Using the DFS tools, an administrator selects which shared
folders to present in the namespace, designs the hierarchy in which those
folders appear, and determines the names that the shared folders show in
the namespace. When a user views the namespace, the folders appear to
reside on a single, high-capacity hard disk. Users can navigate the folders
in the namespace without needing to know the server names or shared folders
hosting the data. DFS also provides many other benefits, including fault
tolerance and load-sharing capabilities, making it ideal for all types of

We heard about the advantages and disadvantages of using DFS. Dirk showed
us how to activate SAMBA and DFS giving configuration settings and BASH
shell scripts to automate the procedure from the Command Line Interface (CLI).



rsync is an open source utility that provides fast incremental file transfer.
rsync is freely available under the GNU General Public License version 2.
It allows you to backup files from a Linux box to another Linux box. Using
cygwin you can run Rsync from a Wndows box to archive files to a Linux box.

Dirk showed us how to sync one Linux box to another. Updating only the files
that have changed to protect from data loss. He gave us three suggestions to
avoid problems. #1) Does not copy ACL’s. Create a file with getfacl to recreate
the acl’s if you have problems. #2) Use Logical Volume Management (LVM)
to create a snapshot of what you are backing up. #3) Use ssh transfer method.
a BASH shell script was given that performs these three tasks from the CLI.

Next we saw how to connect a Windows box to a Linux box for file system
archiving using cygwin.. cygwin allows you to run Linux applications on a
Windows box. The opposite of wine, which allows Windows applications to
run on Linux. Dirk gave the BASH shell scripts that accomplishes the tasks
listed below automating the procedures from the CLI.

How to Get Windows Files Synchronizing to Linux:
#1) Install cygwin.

#2) Get ssh working. [see ssh presntation]
#3) Script your way to Rsync bliss.

Presented by Kevin Wixson

See the presentation slide show here.

Inkscape is an Open Source vector drawing tool with capabilities
similar to Adobe Illustrator, Macromedia Freehand, and CorelDraw
that uses the W3C standard scalable vector graphics format (SVG).
When you consider that Adobe Illustrator costs over $450, that
the proprietary source code is not user modifiable, and that no

personal support is available from developers... Inkscape shines
brightly. Direct end-user software support from Inkscape developers
is possible. The production program is FREE! Kevin displayed a
slide presentation and a live demonstration of Inkscape stable
release 0.41 that is intended for current production use.

He started with an introduction that explained the difference
between bitmap/raster images and scalable vector graphics. He

showed us examples of graphical images created using Inkscape.

We heard about the WC3 SVG standard and how the math of the
Bezier curve is fundamental. A statement was made by one
of the observers that, "What vector graphics do for images is

like what Postscript did for text." In the demonstration we
saw how to use various tools including the primary "Pen Tool."
You could hear frequent exclamations including 'wow' and 'nice'
from the presentation attendees. Learn more about the WC3 spec.
SVG is a language for describing two-dimensional graphics and
graphical applications in XML.

Support? The developers frequent IRC and can be found at
#inkscape. Check out
http://www.freenode.org for info. There
is a mailing list. Copious amounts of information is available
at the Inkscape Wiki

GPL’d desktop publishing Scribus, image-editing GIMP , and
vector graphics Inkscapes combine to give Open Source and
Linux a powerful suite of applications that are improving every
day through collaboration.


Kevin is a member of the documentation team for Inkscape,
presently a volunteer creating the working version of the

user’s manual. The link for the manual is located here:

Do you want 3415 public domain graphics that are in vector graphics
format? Kevin recommends that you visit Open Clip Art’s web site:

Presented by Jon Smitley

Almost everyone knows how the TV quiz show Jeopardy is
played. Hasn’t it been a very successful edutainment

format TV game show?

Back in October of 2001, on Halloween, KLUG members gathered
in Dunbar Hall on the WMU campus for what was being billed
then as Open Source Jeopardy. Adam Williams used a classroom

chalkboard to list the answers and KLUG's Brian Ritz was the
scorekeeper. Adam had the questions written on cards which
were sorted by points and categories. Adam transferred that
info to an entire wall of chalkboards. That was a bunch of
writing and the manual score keeping was rather difficult.
In following years, the name was changed to Geek Jeopardy and
Adam put all the information into a spreadsheet application.
That sure beat all that writing.

In anticipation of celebrating the 5th year of the annual
festivities, KLUG Linkmaster (KLUGware too) Jon Smitley put
Open Source tools together with the game process to create an
application with a graphical user interface for the display
of the categories, points, and answers. It even handles the
game scoring. Wheel of Fortune's Vanna White was apparently
unwilling to perform the scoring duties for us. It does include
an MC display that provides the correct questions. Even Alex
Trebek could handle this application. He also had the buzzer
system working just like it was expected to. There are Jeopardy,
Double Jeopardy, and even Final Jeopardy sessions included.

Jon calls the application "AMPardy." The Merv Griffin attorneys
vigorously protect their intellectual property so care was

taken to not be taunt copyright actions. AMP stands for the
Apache web server, the MySQL database, and the widely-used
general-purpose scripting language that is especially suited
for web development and can be embedded into HTML… PHP! Were
any problems encountered? Only minor ones and that is why all
software is beta tested.

Jon, with some help, did an excellent job of putting together
this AMP application. You can be sure it will be ready for
Halloween 2005 and the annual KLUG Geek Jeopardy party. There
was some uncertainty about whether or not this application could
be released as Open Source code without running into legal
problems. We’ll find out more about that in the future.

The test topics included Geek Cinema, CPU Architectures, YRO,
Redmond, LDAP, Samba, X11, Slang, XML, CLI, "Things that
spin", and "RFC Potpurri" that were snagged from a previous
year’s spreadsheet archive file. The software testing session

was enjoyed by a raucous crowd of previous year Geek Jeopardy
enthusiasts. No one had more fun than the originator, Adam.
He got his first chance to show how much he knows and how
good his memory was from back in October of 2002. Adam did
blow the rest of the teams out of the water but you could tell

that he was not the only player with quick fingers and a good
knowledge of the Open Source technology and community.

It was 90 degrees, wonderfully humid, and partly sunny
tonight. To our surprise, 14 people attended the monthly
General Assistance (& Install) Meeting. Chair John
Bridleman launched into the abbreviated introduction
and made quick conclusion.

Snacks where abundant, the basement WAP was working,
The were no install assistance requests this month. Is it
so easy now that nobody needs help with installs? Well,
that is great… KLUG is ready if anyone does want help.

An introductory question tossed into the audience was
about Apple’s decision to get their processor chips from
Intel and not from IBM (originally Motorola).

While many Linux related discussions were spawning
around the room, a desktop box with a long forgotten
BIOS password was cleared employing the motherboard
jumper technique. Several solutions were offered by the
group. Access to the BIOS was needed to get the box
to boot off the DVD/CD for an install at a latter date.

Brock and Leola got help from Dirk, Bob, and Andrew.
They had their 64-bit Compaq (HP) laptop their for some
assistance. Leola wanted printing help and found out
how she could get the output she wanted. The printing
of a #10 envelope was an accomplishment. Leola also
had lessons in burning a CD-ROM. She took root to
avoid problems.

We discussed the Lexmark lawsuit and the Digital
Millennium Copyright Act (DMCA) legal implications.
The chip in the laser toner cartridge has been duplicated.
