Sure! Here's what I'm doing. Remember, I've been a K12LTSP
school for
many years so we already have quite a bit of experience with
Linux and
thin-clients. This year marks a total shift over to
Edubuntu....not just
on the thin-clients, but on the desktops as well.
I have a K-8 school of about 600 users. We have 2 Edubuntu
servers
running in DHCP Failover/Load balancing mode see below for
link to how-to
in the wiki. I have a Samba/LDAP server (running on Ubuntu
Server 7.04)
as the central auth point for all workstations and servers.
This server
houses all the student home dirs and so forth (mounted via
NFS to the
Edubuntu servers). As for Windows....we do that 2 ways. I
have a Windows
2003 Terminal server which the user use the Terminal
Services client in
Edubuntu to connect to the server. The Samba/LDAP server is
also the PDC
(primary domain controller) so I simply have to join the
Windows TS to the
domain and that takes care of users and authentication. All
the users,
profiles, etc live on the Samba/LDAP server. The other
thing I've done
(and this is my grand experiment for this year) is to
install VMWare
Player and a Windows XP VM to each workstation (actually
it's part of the
image....but pushing new Windows VM's will be a cinch....all
I have to do
is push the folder to the machines via SSH or something like
wget). So
the users can either connect to the Windows Terminal
server....or launch
the VMWare Windows XP VM (for running an app on the local
hardware). I
have not installed many apps on Windows....it's simply there
for certain
situations.
I've learned over the years....if the machine boots
initially to
windows....that's what most of the people will
use....regardless of what
else is on there. So this year the machines all boot to
Edubuntu with
windows as the "other" possibility as a VM or TS
connection.
Thus....people do 90% or more of their work in Edubuntu.
As for clients....I need to count at some point. Generally
I can say that
we usually have up to 35-40 concurrent connections at any
one time to the
Edubuntu Terminal Servers. total number of
clients....workstations....laptops...etc....is in the 300
range. At any
one time...up to 200 workstations/laptops can be hitting the
server for
DHCP....Samba/LDAP stuff...etc. Especially when we're doing
NWEA testing.
So....to the person off the street we are an Edubuntu school
as
every classroom machine boots to Edubuntu....thin-clients
and all. Very
cool!
