******* 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 serverNETWORK_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.
Not sure what you mean, again.*In*11.04,*which*I'm*using,*the*closest*thin g*I*can*imagine*is*iTalc.*
HTH. And please try the compression and give us some feedback...--
