Hi Edubuntu Frds
Here I have some doubts on Edubunt 10.10
1. How to speed up the Edubuntu thin client
I found this article http://ubuntuforums.org/archive/index.php/t-368869.html
about compression.
Looking around the configuration files I didn't see any compression
enabled in /var/lib/tftpboot/ltsp/i386/lts.conf so I added:
## SSH compression between LTSP client and server
NETWORK_COMPRESSION = True
Subjectively, using Firefox and LibreOffice apps feels a LOT faster.
But with 11 thin clients working (4 of them using TuxType and 1 using
TuxPaint, the rest on Firefox or something else) the Dual Core was
showing 2.8 to 3.4 workload (too high!) and the network throughput was
still a solid 1.2GB per minute.
I know Tux-'x' is responsible for that, mostly, and is so slow it's
unusable with more than 2 people using it at a time). But do give
compression a try. I think it makes a noticeable improvement for
browsing and general work.
(Aside: does anyone know of a decent touch-typing program that isn't
as bandwidth intensive as Tux?)
And I must say, though I haven't tested exhaustively, while Firefox,
LibreOffice Write and Calc still take a fairly long time to load
initially; once they're running they seem fine. And then again, they
only take about as long as OpenOffice takes to start on a normal PC. ;)
Overall, I'm very disappointed with the performance of Edubuntu
compared to, for e.g., MS Terminal Server. One of these days I'd like
to get around to booting a PXE basic X client and running an
xtightvncviewer session to the host.
2. How to create thin client user on the server
Not sure I understand the question.
From a terminal:
sudo adduser arbusername
Or use [System] [Administration] [Users and Groups] on the Gnome
desktop.
(Under Unity you can just click on the [+] application launcher and
start typing user... or find it under System Administration.)
3.How to install the thin client manager.
Que?
Not sure what you mean, again. In 11.04, which I'm using, the closest
thing I can imagine is iTalc.
HTH. And please try the compression and give us some feedback...
