Installer la version beta de fl_Teachertool
En attendant de disposer d'un paquet Debian pour cette application, vous pouvez suivre les instructions suivantes (attention, nous parlons bien d'une version beta, à manipuler avec précaution) :
to setup x11vnc on clients:
http://doc.edubuntu-fr.org/clientleger_x11vnc include -shared option in x11vnc command
there is an english version https://wiki.edubuntu.org/InstallX11VncOnLtspClients
but it did not have the cp sources.list line Don't forget to exit the chroot
sudo su apt-get install build-essential apt-get install libfltk1.1 libfltk1.1-dev apt-get install libxpm-dev apt-get install vnc4server apt-get install xtightvncviewer apt-get install zlib1g-dev apt-get install libjpeg-dev apt-get install xscreensaver
download fl-tt source from here
untar my tarball then
cd "le-dossier-fl_teachertool" make && make install chmod +x /etc/X11/xinit/xinitrc gedit /etc/X11/app-defaults/XScreenSaver
near the beginning of the file there should be this line
replace the word "random" with "blank" (no quotes)
download vncreflector source code from here http://sourceforge.net/projects/vnc-reflector/
untar make cp vncreflector /usr/bin
follow step 2-5 here for control/monitor http://www3.telus.net/public/robark/Fl_TeacherTool/installationk12ltsp.html#monitor
1. Edit the file /opt/ltsp/i386/etc/lts.conf and uncomment (i.e. remove the "#"): X4_MODULE_02 = vnc 2. Become root: su - 3. Make a password for the vnc-session: /usr/bin/vncpasswd 4. Copy the password file into the ltsp-tree: cp -a /root/.vnc /opt/ltsp/i386/root/ 5. Log out of root session: exit 6. Reboot your clients!
Allow Non-Root Users to Run Fl_TeacherTool
This enables teachers who do not have root password to run fl_teachertool.
1. Create a new group called "teachers" using system-config-users You can run this from GNOME using System, Administration, Users and Groups. 2. Add the "teachers" group to each user who needs to run fl_teachertool. 3. Become root with $su - 4. Run: visudo This is a special editor for the sudoers file. 5. Add the following line to the end of the file using vi editing techniques: %teachers ALL=NOPASSWD:/usr/local/sbin/fl_teachertool Enter at least one blank line at the end of the file. If you don't know vi then just goto the last line and hit the letter "i" for (insert) then type the above line, hit enter, then hit the escape key. Now type :wq and hit <enter>. This saves and exits. Alternatively, you can set the EDITOR environment variable to a different text editor. nano is a friendly editor: export EDITOR=/usr/bin/nano; visudo 6. If your fellow teachers are not comfortable typing "sudo /usr/sbin/fl_teachertool" then add an alias in file .bashrc (notice it starts with a period) in the home directory of the people who will run the program. # User specific aliases and functions alias teach='sudo /usr/local/sbin/fl_teachertool' Then they only have to type teach or alternatively put a launcher icon with the command sudo /usr/local/sbin/fl_teachertool on their desktop.
Hopefully I have not forgotten anything. Oh, fl_teachertool must be run as root
Be patient with this version as it runs slower than it did on k12ltsp.
I am also currently developing version 0.50. Enjoy.
