It seems that the DHCP is the problem then.  

Are you certain there's a good network link between the thin client server
(and its dhcp server) and the thin client?  Can you start this running:

	 tail -f /var/log/syslog | grep DHCP

and then boot a client.  If the DHCP request makes it you should get a line
	Feb  3 13:12:35 robin dhcpd: DHCPDISCOVER from 00:1d:d9:3e:da:eb via eth0

where the mac address shown is that of your thin client.  If you don't get
that, there's some loss of connectivity between server and client.

Webmin is not supported in Edubuntu.  Some people use it for managing
users, but it's not supported.  It sounds like it modifies
/etc/dhcp3/dhcpd.conf which is ignored if /etc/ltsp/dhcpd.conf is present.

It looks fine.

My mistake, those files don't need to be in the chroot, they need to be in
the tftp server directory, that is /var/lib/tftpboot/, so you should have


You might as well remove the copies you made above.
