Feisty:Why does the ltsp-build-clients script needs a Internet connection?

[Philipp Hanselmann]

Hi,

I can report that  Edubuntu is now working at the teacher college with 
20 thin clients (and about 20 fat clients using the server as 
proxy/firewall).

The reason why it was not working was, that their network setup was 
completely messed up. I figured out that they connected the two hubs  
from the internal zone and from the external zone (Internet) together 
with a network cable !!! And even some parts of the local network was 
connected to the hub in front of the firewall (Edubuntu server with 
shorewall and squid). This was working for years now with our actual 
ltsp solution, but Edubuntu (Shorewall) refused this network setup ;-)
