Hmm. It doesn't sound like an fl_teachertool problem. It sounds like a
configuration problem with vnc. Usually people have problems following
the instructions here
http://www3.telus.net/public/robark/Fl_TeacherTool/installation.html
but I don't think that's your problem.

I have not tested on Fedora 7.

This is not supposed to happen. It sounds like the mechanism to start
Xvnc and provide a gdm login by xinetd is borked somehow. I can't
remember how Eric set that up. It's always just worked like magic in
k12ltsp for me.

Here is an idea, try this. Instead of
teachertool-vncviewer localhost:1
try
vncviewer localhost:1
If that works then try recompiling tightvnc; if it doesn't then it's
your systems vnc setup that's messed up.
