WOW! Faster than iTALC and pretty easy to install as well. I'll be letting you know how this continues--Now to translate some button names--or alkisg would you do them since I can't copy paste them into a translator? I'll make it a neat write up though and put it into the wiki when I've tested it a bit more. This is cool :) David <div class="gmail_quote">On Wed, Jun 16, 2010 at 1:23 AM, Alkis Georgopoulos <<a href="mailto:alkisg@gmail.com" target="_blank">alkisg@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Στις 15-06-2010, ημέρα Τρι, και ώρα 20:30 -0500, ο/η David Groos έγραψε: <div>> alkisg told me about a series of scripts that sound great that he uses > instead of iTALC so I'm going to give them a try.

I'd be glad to help if some python/shell programmer wants to do it, though. It only works on Lucid. The toolbar buttons should replace most of iTalc functionality, and are: Wake on lan (the clients should be declared with their macs/hostnames in lts.conf for this to work - that's done from the -greek- menus), Logoff, Reboot, Shutdown, Broadcast teacher screen, End broadcast, Execute a command on the clients, Lock student screens, Unlock student screens, and Client properties. The screen broadcasting is about 5 times faster than iTalc, and in my experience, it's much much more stable. The clients and the users are autodetected LIVE as they become available - there's no need to put them in a configuration file. The client daemon only needs 1 MB RAM (=it's just a /bin/sh). xvnc4viewer is automatically called on demand. The teacher broadcasting also works in the ldm login screen, where the users have not logged on yet. Currently the teacher needs to have sudo rights to run the GUI, but for the "classroom management" part this requirement could be easily dropped, as the GUI communicates with the networking backend over a unix socket owned by some group. So it's very easy to make it so that it can be used by anyone in the "teachers" group. The fat/thin chroot generation wizard won't be useful outside of Greece as it is though, as it's too much focused on local schools. If some programmer wanted it'd be nice if he generalized it though, as the generated fat chroot allows for mixed labs (both thin+fat clients can boot off of it) with min RAM=64Mb. It's working amazingly well. To sum up: DON'T install it on any production environments without trying it on a test lab first, and DON'T install it if you're not happy with only understading the toolbar (the rest is in Greek) :) More on this in 2 years.
