Re: [K12OSN] Remote client desktop

I am wondering what the status of FL_TeacherTool is for LTSP 5?

Do you need Xvnc launched via inetd or xinetd?  Your message said xinetd,
but the link to my notes that you gave references inetd. I've also got info on making it launch via xinetd. Presumably, it should be xinetd since this
would run on the server, right?  Let me know and I'll tackle getting it
working on F11 this summer.

That's great Peter. Yes xinetd should start the vncserver (Xvnc) on
the server for broadcasting.
x11vnc on the client is for monitoring/controlling/snapshots

I appreciate the help Peter.
Thanks to Jeff for getting this ball rolling by getting x11vnc to work
and thanks to Barry for making automagic rpm packages and testing.
Fl_TeacherTool is still alive.

try disabling iptables from running on your fc11 server at startup in

Also another stupid question,,,you DO have a user actually logged into
the TC's and not just powered up?


I thought there were users logged in, but it appears that the ones that
had rebooted the client had also logged out before I fired up

iptables is disabled.

I'll check again when I am sure there are clients logged in.

I need to make a some  changes to fl_teachertool so it will work with
LTSP 5 Fedora. I will download Fedora 11 (when it's released next
week) and start porting it after June 16 (after report cards). It
shouldn't be too hard. However, I need help with these issues:

1) Installing and  running a vnc server on the client (either x11vnc
or vnc.so module for X or something else
       see http://www.realvnc.com/products/free/4.1/x0.html ) Sounds
like Jeff has almost got this done.

2) automatically launching Xvnc (vncserver) through xinetd to bring up
a gdm login window when you connect to localhost with vncviewer. I am
pretty sure Peter has a how-to on this (calling Peter)

found it
I have not tested it though.

If people (maybe Jeff, Peter and Barry and/or others) can help add
these 2 features to Fedora then I will commit to porting
fl_teachertool to LTSP 5 Fedora 11 this summer. I suggest we do the
work on Fedora 11 as it's less than a week away.
