Yeah i know, but the 'gedit' is an example, what i want to do is invoke 'vncviewer' so a teacher in a school can view a boy's desktop. I've made a controller that is able to shutdown all computers and more things.
The idea for the vncviewer is that the teacher choose one of the computers and the vncviewer appears in his desktop. When i'm be able todo this i'll fix the permissions and perhaps www-data can't invoke anything but the three or four neccessary commands. 2010/10/15 Diez B.
