If you are using K12LTSP 5.0 1) Edit the file /opt/ltsp/i386/etc/lts.conf and uncomment (remove the "#") from the following line: X4_MODULE_02 = vnc 2) Now you'll have to make a password for the vnc-session. Run this command as root user: /usr/bin/vncpasswd 3) Again as root user copy the password file into the ltsp-tree cp -R -p /root/.vnc /opt/ltsp/i386/root/ 4) Reboot your clients As for allowing teachers to run the program. Setting Up Fl_TeacherTool to run with sudo: Step 1 Create a group for teachers using "system-config-users". For example 'teachers'. Then add that group to all the users who you wish to run fl_teachertool. Step 2 become root with $su - Then run "visudo". It's a special editor for the sudoers file. Add the following line to the end of the file using vi editing techniques %teachers ALL=NOPASSWD:/usr/sbin/fl_teachertool make sure that it's not the last line (in other words: don't forget to hit enter) 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 (hit enter) this saves and exits. Step 3 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 like this # User specific aliases and functions alias teach='sudo /usr/sbin/fl_teachertool' Then they only have to type "teach" or alternatively put a launcher icon with the command sudo /usr/sbin/fl_teachertool on their desktop Enjoy! </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>-- Mel Wade "I love it when a plan comes together." - Hannibal <a href="http://www.melwade.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">www.melwade.com</a> </div> _______________________________________________ K12OSN mailing list <a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:K12OSN@redhat.com">K12OSN@redhat.com</a> <a onclick="return top.js.OpenExtLink(window,event,this)" href="https://www.redhat.com/mailman/listinfo/k12osn" target="_blank"> https://www.redhat.com/mailman/listinfo/k12osn</a> For more info see <<a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.k12os.org" target="_blank">http://www.k12os.org</a>> </blockquote> </div> -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool <a href="http://www3.telus.net/public/robark/Fl_TeacherTool/">http://www3.telus.net/public/robark/Fl_TeacherTool/ </a> C++ GUI tutorial <a href="http://www3.telus.net/public/robark/">http://www3.telus.net/public/robark/</a>
