Default DHCP on 2nic system problem

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

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

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

can you reply with some extra information:

1. run "ps aux |grep dhcpd" and see if the dhcp server is running and on
what interface, eg.

gavin@robin ~> ps aux |grep dhcpd
gavin 19810 0.0 0.1 3004 764 pts/6 S+ 14:13 0:00 grep dhcpd
dhcpd 31979 0.0 0.0 2872 308 ? Ss Jul10 0:02 /usr/sbin/dhcpd3 -q -pf /var/run/dhcp3-server/dhcpd.pid -cf /etc/ltsp/dhcpd.conf eth0

2. Run "/sbin/ifconfig" to check what ip addresses are on what interfaces.

3. The file /etc/ltsp/dhcpd.conf

If you give us the output of these three, we'll get some idea what your
problem is.

Hi all,

I have downloaded the desktop and add-on cd's. can someone help me
with an install model?

I have 10 x P4 2 Ghz 512 mb Ram 80GB hd* PC's in a small school lab +
2 more in the head teachers office. I want to expand 2 6 more for a
total of 18 units.

I want the kids to be able to log in from any machine in the lab
I want the
teachers to be able to log in from any machine in the school

Do I have to use server/thin client or can i do this with the desktop
install? i.e. having authentication and user space on just one box but
run all the applications locally.

Thanks so much!
David

Thin clients would be a very quick way to do this, but installed desktops
have their advantages too.

You can store /home/ on a server with NFS, then mount that directory as
/home on each desktop.* This will mean that user's files and settings are
available from any computer.

You can use any of a number of centralised authentication schemes (LDAP,
NIS, AD) to allow consistent logins on any computer.* I've never needed to
make rules about which computers certain groups can login to, but I'm
guessing that should be pretty
doable.

Dear Gavin,

Thanks so much for replying. I am starting this tomorrow !!!

The reason I think I'll do full desktop installs is that all the PC's
are identical
and the spec is not good enough for a server and too
good for thin client (they had bought the gear already)...I don't want
to cannibalize the existing machines or spend anymore money.

Then again.... The school has an expansion plan to double the number
of computers. Maybe I can make 2 thin clients from 1 fat one

Regards
David

That makes reasonable sense.* The only trouble with desktop installs is the
maintenance is a lot greater.* You need to maintain the install on each
desktop individually.* Some of this can be automated, but thin clients
really are one machine.*

I'm not sure of the status at this point of the diskless fat client (or
whatever it's called).* The idea is that your desktops network boot, and
take their applications, etc. from the server as with thin clients, but
they actually run applications locally on the desktop, rather than running
them on the server.* In principal, this should give you a single install to
maintain, but use the computing power of the desktops.

I'm not honestly sure if this works well at
this point though.* I've never
done it myself.

Gavin
