You need to install SAMBA
 
Hi,
*
You surely need to install SAMBA for your Ubuntu installation to interract with MS*Windows network and do some configuration on Ubuntu machine regarding those drives on Windows server in order to gain full access to the content. Read the help file that comes with Ubuntu, it is very straight forward.

If you can see the Windows drives, you should be able to connect with
this format (assuming you are being prompted for a username and
password):

DomainUsername
Password

I cannot remember if the slash after the domain is a forward or
backward (try it both ways).

Hope that helps,
Charles

See this doc
https://help.ubuntu.com/community/Samba/Kerberos

You need the Kerberos library for connecting the Win2003 server's sharing

Hope this help you

Hi all,
I just setup up an LTSP server on ubuntu 8.04 and the edubuntu add on
package. I installed everything but when I connect a client it gives me the
following:
PXE-T01: File not found.
PXE-E3B:TFTP Error - File not found

The server is 64 bit and the clients are 64 bit capable. I did some digging
and I found my /etc/ltsp/dhcpd.conf. This is what it has:
#
# Default LTSP dhcpd.conf config file.
#

authoritative;

subnet 192.168.0.0 netmask
255.255.255.0 {
* * range 192.168.0.20 192.168.0.250;
* * option domain-name "example.com";
* * option domain-name-servers 192.168.0.1;
* * option broadcast-address 192.168.0.255;
* * option routers 192.168.0.1;
#* * next-server 192.168.0.1;
#* * get-lease-hostnames true;
* * option subnet-mask 255.255.255.0;
* * option root-path "/opt/ltsp/i386";
* * if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
* * * * filename "/ltsp/i386/pxelinux.0";
* * } else {
* * * * filename "/ltsp/i386/nbi.img";
* * }
}
I know the error that PXE is giving me is* because I did not run this
command

ltsp-build-client --arch i386

and the i386 image file is not created. My question is:
Is it possible to
have amd64 and i386 image files and select which one the thin client uses to
boot? Maybe by modifying the if statement in dhcpd.conf or have options on
boot of the thin client?

Thanks

For 64 bit clients, you need to feed pxe with amd64, not i386. So change
your dhcpd.conf file to have /opt/ltsp/amd64

The /opt/ltsp/amd64 directory and the image should already have been created
when you installed the LTSP server.

Kind Regards,
David

Thanks for your reply. But my question was if it is possible to have both
chroot architectures (amd64 and i386) and have the client select which one
to boot from. Anyway, I created an i386 image and it the clients boot fine
and I can log in through the GDM. My problem though is that I cannot log in
to the thin client
through the command line. I followed this guide:
https://help.ubuntu.com/community/EdubuntuFAQ?action="">
when I try to log in as root I get the error that my account is
expired.
Is there anyone that has a solution to this?

Thanks

Dear Ubuntu Techies
and* Users,

Our school has been on Edubuntu for three years now and we have been happy
with it. Last year we used as server an Intel Core-2 Duo with 4 GB RAM.

This coming school year I plan to add more thin clients, from an existing 16
we plan to add about 24 more. The thin clients we will be using this time
are old IBM Celeron 766 32 MB RAM we got from a second-hand computer shop.
But if we will add more thin clients then we would need more than 4 GB RAM
(RAM - 512 MB Server, 128MB per thin client). In this case I believe we need
to use the 64-bit version the fact that the i386 could address only up to 4
GB RAM.

Questions:
* (1) Will the 64-bit version work with Intel Core-2 Duo?
* (2) If it will work (or I will use an AMD 64) would there be NO problem if
the thin clients are 32-bit?
* (3) I tested a unit (32 MB RAM) and it worked with Edubuntu 7.10. Is 32 MB
enough or I
need* 64 MB for 8.04?
* (3) In case the setup for 64bit Server and 32-bit client will NOT work:
* * * (3a)* Will it be possible to divide the thin clients (to divide the
CPU load) across two servers (4 GB RAM each) but still share a common disk
system?
* * * (3b)* Will it be better to have two separate network servers and use
just enough thin clients until the server runs out of RAM required for the
clients? How may users access their files in case they logged in the other
"network?"

Thank you very much in advance. Your previous help have been very useful
indeed.
