Complete automate installation of an SkoleLinux network
Hi,
after trying out some things and encountered several error-messages, i
find a way, to install a SkoleLinux network with double boot computers
(Windows / Linux) automatically. And another way to install the Debian
clients also automatically but faster. But i have some further question,
hopefully someone can help me. First a short overview about the install
process. If there is any interest, i will write an article for the wiki.
1. This is the situation in my school, maybe someone knows a better way,
as described below:
We have a common network with another school, which is in the same
building. We also have an large wlan-grid. All in all, there are 78 PCs
and 54 notebooks (8 different hardware-architectures, but 4 of them only
distinguish by the harddisk). The notebooks access the network using
wlan. On the most PCs and on all Laptops linux and windowsXP are
installed parallel (or will be). There are several proprietary software
which runs under windows and with wine under debian. Up to now, we had
novell netware 5.* running on the server, no dhcp.
First question:
Is it possible to assume the user-names from the novell server?
Passwords doesn't matter.
2. Installation of the double-boot-clients
I have a second client, which run a (small) debian-system. I installed
drbl and clonezilla server edition ( http://clonezilla.org/ ).
Fully install one client of every hardware-architecture. Setup
clonezilla that way, that it catch the image. Reboot this client using
pxe and the image will be create an restore on server. (it needs ca. 2
min pro 1GB). When finished, setup clonezilla to share the image using
multicast --> start the clients, you want to get this image --> be sure,
these clients boot via pxe. After this, restoring image will begin
(without any interaction, it will take ca. 1,5 min pro 1 GB).
It is possible to run clonezilla SE on tjener, but i think it isn't a
good way.
So my second question:
*Up to now, i've to change the windows-hostname manual. Is it possible
to share the hostnames for the windows-clients automatically?
*Till now, i poweroff tjener, because i don't know how to change the
address of the pxe-boot server. I thought, there have to be an entry
like this
----------
next-server 10.0.2.3;
----------
but, Petter Reinholdtsen told me, that it is in the ldap-database. But i
don't know how to change it.
*Is 10.0.2.3 a good IP-Address for a second server in a skolelinux-network?
* I've to change the windows-hostname manually. Is there a possibility
to set them automatically?
3. Installation of the debian clients
On server install SystemImager ( systemimager.org ). Create an image of
the client which will transfer via TCP to the server. On server select
the clients, which should be installed. When start or rebooting this
clients, they get the image while booting over PXE. I set up 5 clients
in my test-environment, it takes 6 minutes. I will use this procedure to
install new software on the "without windows" clients or update them.
But still the problem is, i have to install the new software on 4
computers and have to build an image of this 4 computers.
So my third question
*Is it possible to create something like an 'universal bootimage', which
can be installed on all clients, independent of the hardware-architecture?
I had some attempts to run scripts to install software and update the
clients remotely using rsh ( http://en.wikipedia.org/wiki/Remote_Shell
), but at least it is not secure for network use, because it sends
unencrypted information over the network. Does someone knows a better
way to run scripts remotely (of course cfengine, but it seems to get a
big project, in the face of 400 sites of manual!)
Has someone experience using opsi.org and m23 ( m23.sourceforge.net ),
and can tell me, how to configure them using tjener (lenny).
Thanks, Martin
