Ich halte die Texte fuer den jeweiligen Zweck (CD-Einleger, Quick
Install Notes) fuer gelungen. Ich habe daher etwas Feinschliff
betrieben, weil ich glaube, dass wir sie fuer diese Zwecke noch gut
brauchen koennen. (siehe Anlagen)
Ein Werbetext auf einer UNESCO-CD -- auf der dann auch noch viele andere
Sachen drauf sind -- muesste aber IMHO noch etwas anders formuliert sein.
Wie beim Treffen letzten Donnerstag festgestellt wurde, ist es auch
wichtig zu klaeren, _an_wen_ die UNESCO-CD verteilt werden wird.
Stichwort: Zielgruppe.
Diesbezgl. wollte Kurt nochmal mit seinem Kontakt Ruecksprache halten.
[Das komplette Protokoll wird morgen (Sonntag) fertig.]
Viele Gruesse,

Skolelinux: Short summary for a CD cover

[ Logo, wallpaper, background picture, bells and whistles ;) ]
Skolelinux is a unique Linux distribution originated with the idea of
providing a complete environment for schools. Thanks to a dedicated
community, mostly in Norway and Germany, it has come a long way.
Skolelinux is a derivative of Debian with some major additions, such as
a) a comprehensive client-server model
b) highly automated installation
c) a central graphical system administration
?> d) additional software specially for schools
The client-server model makes Skolelinux unique among other Linux
distributions which are targeted for use in schools.
This model differentiates between three flavours called "profiles".
Main-Server
-----------
You must have a "Main-Server" in your LAN which provides a whole lot of
services: file server (e.g. Samba) exporting user data, DHCP server for
your clients, centralized user authentication using LDAP ...to mention
only a few.
On the "Main-Server" no graphical system (GUI) runs by default. Once
up and running you can do all the administrative tasks from any browser
over the network.
Workstation
-----------
A "Workstation", on the other hand, runs a GUI. Namely XFree84 (4.0)
and KDE (2.2). As already mentioned the users' authentication and data
are fetched from the "Main-Server".
Thin-Client Server
------------------
Another kind of a "Server" is the "Thin-Client Server". Thin-clients
with no storage at all can boot and run from the ressources on these
Servers. Generally, the Thin-Client Server has a second network card
for connecting to all its thin clients.
[ ubiquotious diagram here, with clever DTP as background pic? ]
Flexibility
-----------
If you have a single machine and want all these features in one,
there is no problem in combining the profiles above in any order.
In case the web-based administrative interface is not sufficient for
a special need, the Skolelinux distribution remains Debian. You have
all the advanced packaging facilities of Debian intact.
IMPORTANT
---------
a) The default installation takes over the harddisk partitioning for
you. This also means that all the data already on the disks will
be lost!
b) For obvious reasons a Skolelinux installation does not provide an
uplink to the Internet by itself. Therefore you must have a gateway,
a bridge or a router in the network. Just enter the IP-address of
the standard gateway during installation.

Skolelinux: Quick installation notes
------------------------------------------------------------------------

fixed typos + wording
========================================================================
A. The first machine in the network has to be the Main-Server.
Step 1
------
Clear all your data from the harddisk! Set the BIOS to boot
from CD drive, insert the installation CD and boot the computer.
For the default Skolelinux installation just press <Enter> at the
"boot:" prompt.
You will be requested to choose a profile. Depending on your
requirements choose Main-Server, Workstation, Thin-Client Server or
any combination of them. For example, if you want to have a GUI and
work on the Main-Server, add the Workstation profile.
Note: The profiles Standalone and Standalone-extra are still
experimental.
The message "Are you sure to partition automatically?" appears. As
you have backed up all your data, you can say "yes" here.
Step 2
------
The install program will partition and format the disk and install the
base packages. The CD will be automatically ejected.
Set the BIOS to boot from harddisk and press <Enter>. The computer
will boot with the base system.
Step 3
------
After successful booting from the harddisk, the base system continues
to install the full package collection. You will be requested to insert
the CD again. This will take some time.
Step 4
------
After copying the packages, auto detection of hardware starts. It is
important that your ethernet card is in the database. Skolelinux does
its own network configuration here, which you can fine tune later.
Step 5 (only for Workstation and Thin-Client Servers)
------
X-Window detection starts. Set your monitor and graphic card properly.
Step 6
------
You must have noticed that we haven't created any normal user in the
box. The idea is that this administration task is done using the
web-based administration tool, a cutomized version of webmin.
Open a browser and request http://localhost:10000 if it runs on the
same machine. Otherwise http://<ip-address>:10000 [without <> of
course].
B. Installing Workstations and Thin-Client Servers
Repeat the same steps as in A for each machine.
