Thanks Jeff,
We have two network interfaces eth0 and 1,
Moreover would like to use Edubuntu 11.04 as it comes with many
educational software. When I tried installing Edubuntu 11.04 it took
lot of time without success.
Server already have Windows 2003 , Red Hat
and while installing Edubuntu, (had to use manual partitioning as
earier EDubuntu 10.04 was there) it got stuck at step where it kept
saying "removing conflicting files ...." and was at that for 40-45
mins. I had to reboot and installed 10.04 then.
Does Ebubuntu 11.04 takes this long for installation and
partitioning? Did I miss anything?
Thanks,
Leena

Hi,
We are trying to setup Edubuntu 10.04 in school
and get image on thin client machines. Edubuntu
installation on server and LTSP installation goes
fine.
When try to connect client machines doesn't go
beyond connection window and shows blank screen.
Details of the setup and hardware and changes we
have done so far are listed below......sorry it's
a long mail.....this issue is very urgent for us
and hoping that someone would have done similar
setup or have come across similar issues might
able to help us....
questions: After the setup on server, as for
client machines we are unable to receive response
when we ping clients IP from server (client
machine, server and hub are on).Â*How
to check if dhcp is running?
ps -A | grep dhcp
Â*Â*
Â* Â* Â* Â* Â* Â* Â*on most documentations on net I have
read for thin client setup they change
network/interfaces file and connection to 'STATIC'
instead ofÂ*
'dynamic' is it required?
Details:
Hardware
used:Â*
Server-HCL computer-2GB RAM, 160GB Hard disk, two network
cards
Clients: connected to 10 Thin Clients connected to server
on LAN, no Internet connection here. Client machines has
connection window-Winbee connection manager for login.
What we did so far:Â*
Installed Edubuntu 10.04 on server. After it was over when
the pop-up appears for restart now or continue testing (to
install LTSP).
At that we clicked on 'Continue Testing'- as we wanted to
install LTSP (Linux Terminal Server)
For network connection eth0 was shown as used, so we
selected-eth1 here.Â*
How many network interfaces do you have?
I noticed when I installed 11.04 last week (for the first
time) that it defaulted to eth1. I knew that I only had one
interface, so I set it to eth0 and everything went better than
expected.
after LTSP was
configured we did reboot computer, and made couple of
changes to config files as follows
Enabled the XDMCP Server by (using N-XDMCP connection type on clients for connection)
copied usr/share/custom.conf file to /etc/gdm/custom.conf and added below lines below [xdmcp] option.
[xdmcp]
Enable=true
DisplaysPerHost=2
[chooser]
[security]
[debug]
Restart GDM
Then edited our interfaces file: /etc/network/interfaces
to following
auto lo
iface lo inet loopback
auto eth1
iface eth1 inet static
Â* address 192.168.0.254
Â* netmask 255.255.255.0
Â* broadcast 192.168.0.255
and finally the /etc/ltsp/dhcpd.confÂ*Â*Â*Â* dhcpd.conf
file to following
#
# Default LTSP dhcpd.conf config file.
#
authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
Â*Â*Â* range 192.168.0.20 192.168.0.250;
Â*Â*Â* option domain-name "example.com";
Â*Â*Â* option domain-name-servers 192.168.0.1;
Â*Â*Â* option broadcast-address 192.168.0.255;
Â*Â*Â* option routers 192.168.0.254;
#Â*Â*Â* next-server 192.168.0.1;
#Â*Â*Â* get-lease-hostnames true;
Â*Â*Â* option subnet-mask 255.255.255.0;
Â*Â*Â* option root-path "/opt/ltsp/i386";
Â*Â*Â* if substring( option vendor-class-identifier, 0, 9 )
= "PXEClient" {
Â*Â*Â*Â*Â*Â*Â* filename "ltsp/i386/pxelinux.0";
Â*Â*Â* } else {
Â*Â*Â*Â*Â*Â*Â* filename "ltsp/i386/nbi.img";
Â*Â*Â* }
}
rebooted the server.
and in client machines, added connection at 'Winbee
connection Manager'- (HCL client comes with these)
Configuring/Setting
up HCL Winbees-4000BVX Thin Clients
for new OS connection, add connection.on top there are
two options,
1. configuration
Name:connection name here (EDubuntu)
Type:N-XDMCPÂ*
click-ok
Description
→Â*Edubuntu
Mode
→Â*Direct
Server
Name →Â*192.168.0.254
XDMCP on →Â*Second
Console
2. connection:click on setup to add Network to check ip
address for client
save. and reboot clients.
After rebooting client machine, when I select my newly
added 'Edubutu' connection and click 'connect'. It shows
blank screen with white mouse cross mark.
The link here:Â*http://www.edubuntu.org/documentation/ltsp-live-
at the very bottom of page says " you simply have to set
the connected workstations to boot from the network.Â* by
going into BIOS". we haven't done that as hcl clients
has Winbee manager to go thr' connection process. Not
sure if we should have really.
Can anybody give any clues to what might have gone
wrong?Â*
Thanks,
