I know some earlier adopters will have noticed this problem, I install Edubuntu classroom server on a system that has 2 nic cards with LTSP activated, but it is just not giving out IP addresses to the clients. I have followes some links on ubuntu forum etc but now solution yet.
Please give me a lead on what is happening, i know it is a problem from my end, because Edubuntu works!
Regards
David

I am the IT Tech at a small K-12 school district. While we are, I guess you
could say, a Windows school, I have been experimenting with various versions
of Linux for a possible roll-out on some of our machines. Anyway, I have
found the Edubuntu product and was going to give it a try but when I go to
install it on a PC it tells me that the software I am using is for X86
machines and that I am running a machine with an i1586 processor. Both of
the machines that I have tried (A Dell GX240 and AcerPower F2) have P4
processors. To my understanding, these should be considered an X86
architecture. Any help with this issue would be greatly appreciated.

You're right in saying that a P4/i586 is certainly an X86 machine.

Are you sure you didn't download the x86_64 CD image?  That's the 64-bit
version of edubuntu.  It might then complain about the cd being for X86_64
machines.

Hello all,

I want to give Olie or somebody some feedback about the download
directions for the LTSP Server install
located at http://www.edubuntu.org/Download. Here's the part that I
think may lead to issues for some downloaders.

Under the section heading titled:

Install Edubuntu Classroom Server (thin client)

  1. Get the Ubuntu 8.04.1 Alternate CD - Don't forget to select the
checkbox for the alternate desktop CD on the download page!

Following the link takes you to
http://www.ubuntu.com/getubuntu/download and the Ubuntu download
dialog. Here you have the opportunity to choose your edition,

Ubuntu 8.04 LTS Desktop Edition - Supported to 2011
Ubuntu 8.04 LTS Server Edition - Supported to 2013

and to tick the checkbox that reads" Check here if you need the
alternate desktop CD."

Because I am a little bit dim, I choose the Server edition, after all
I had just come from the page and section entitled "Install Edubuntu
Classroom Server" AND I ticked the box that said "Check here if you
need the alternate desktop". The download I got was indeed the server
addition (despite the fact that I had also ticked "Alternate Desktop),
which doesn't include (AFAIK) the LTSP installation option. I've
realized my mistake and I am now downloading what I hope is the
correct version.

The reason I bother to bring this up is I could imagine this process
being even more ambiguous and lame  for someone for whom English
wasn't the first language or for someone with a very slow internet
connection. If I'd just taken several days to download the ISO I would
feel really bad!

I think this issue could be solved by:

(1) not letting me near computers ever again or
(2) by putting an extra line under the "Install Edubuntu Classroom
Server (thin client)" heading at http://www.edubuntu.org/Download that
says something like:


1. Get the Ubuntu 8.04.1 Alternate CD - Don't forget to select the
"Desktop Edition" release and tick the checkbox for the alternate
desktop CD on the download page!

Anyway,

my .02

John

That sounds a lot better indeed ...
the https://wiki.ubuntu.com/HardyClassroomServer though is a lot clearer
and points directly to teh download directory with the isos ... it was
tried to get the site on edubuntu.org to comply as close to teh default
ubuntu page as possible which is why this confusion comes up ...
i will try to trigger the change to www.edubuntu.org

ciao

Hi all,

I've decided to take the plunge and do a 'from-scratch' install of
Edubuntu/Hardy with an eye toward getting it ready to replace our 7.04
based Edubuntu installation. So far so good. Sound/USB works out of
the box, flash was easy to install, and building an i386 image for the
thin clients was a piece of cake. Wow! ( I assume once I tie
authentication in to Active Directory via pam/winbind, I'll lose USB
support, but I have a work around from
http://wiki.ltsp.org/twiki/bin/view/Ltsp/LTSP-42-LocalDev#Install_FUSE_on_your_system)

But since I am always tinkering I was wondering if there was a way to
shorten the boot times on the thin clients. I am using Ntavo 6030's
with 512 mb ram/400 mhz via processor. The server is a quad core AMD
64 with 8gigs of ram and gig nic. My boot time on the thin clients
once PXE kicks in is around 70-75 seconds. I know that isn't a really
long time, but if there was a way to cut this down, I'd love to know
about it since I could imagine kids staring at the edubuntu progress
bar as it hung there for 30 seconds and reboot the machine several
times.

Does any one have any favorite hacks to
/var/lib/tftpboot/ltsp/i386/lts.conf that they feel improves the user
experience?

Thanks!

John
