Previous versions of Edubuntu automatically installed a Terminal Server environment. This will no longer be the case in 8.04. You need to install it manually. All packages will be installed with the virtual package ltsp-server-standalone:

aptitude install ltsp-server-standalone

After the installation, your DHCP server will complain and does not start. You need to modify your dhcpd.conf. Edubuntu does NOT use /etc/dhcp3/dhcpd.conf. Instead /etc/ltsp/dhcp.conf is used!

Modify it according the following lines:

#
# Default LTSP dhcpd.conf config file.
#

authoritative;

subnet 192.168.10.0 netmask 255.255.255.0 {
range 192.168.10.100 192.168.10.199;
option domain-name "linux4afrika.local";
option domain-name-servers 192.168.10.1;
option broadcast-address 192.168.10.255;
option routers 192.168.10.1;
next-server 192.168.10.254;
# 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";
}
}

You can now connect a Thin Client to test your Terminalserver. However you will still receive an error message, because there is no Image yet which can be booted.

You need to create it first.

On 32 Bit machines you type:

ltsp-build-client

on AMD 64 Bit machines you need to create 32 Bit clients by typing:

ltsp-build-client --arch i386

This takes some time. If you're done type:

ltsp-update-sshkeys

 

Add user

See link Admin duties for procedures to add user. 

You're finished, your Thin Clients can now boot into your new Terminalserver.
