Differences when using it with thin clients
Very recently, ControlAula has support to work in a thin clients environment using the LTSP project
configuration. Due to the special caracteristics of such environment,
there are some inherent differences between this kind of environment
and an average workstations lab.
There are also limitations, some of them will be removed in the future, but today they are still here
Limitations There are two main limitations:
desktop has to be the ltsp server for the classroom. This is going to
change in the future, allowing any ltsp client to be the teacher
desktop but, using controlaula today in a ltsp envirnoment will force
this setup: if the teacher pc is not the ltsp server, the rest of the
clients will not recognize him properly as a teacher.
& unsharing the printer does not work: the student will be able of
using the printer if the teacher has a printer setup and the student is
in the lp group.
differences are related to the way the application starts inside the
ltsp clients, so this information is just for admins to know how the
application behaves, but it's not useful for end users. Users (teachers
and students) will work the same when using ControlAula in a thin
client environment or in a workstation environment (with the exception
of the above limitations).
- Video broadcasting
works the same in a thin client envirnoment. So, this sentence means
that vlc client starts in the thin client chroot, and runs as a local
- ControlAula adds a localapp skeleton that allows
running applications locally in the thin client. This skeleton is fully
included for iceweasel/firefox, but adding new applications to run like
local applications is trivial.
- If firefox is going to be
run as a local application in the clients, a NAT setup must be set in
the ltsp server, otherwise clients won't be able to access outside.
the ltsp server as the teacher desktop, a mixed environment (thin
clients with full clients) will work, even if the computers are in
different network segments.
