[K12OSN] Releasing Fl_TeacherTool 0.1

[Peter Hartmann]

I don't know what happened.  All of a sudden Fl_TeacherTool isn't
really working, as root or otherwise. The only things it can do is
logoff user and kill processes.      The VNC session window starts
from TT but not on the client.  I'm not sure if this is related but I
was having trouble starting x on all clients temporarily.  The only
things i did was adding sudo users (which I changed back) and the fix
for multiple ssh-agent processes in /etc/X11/xinit/initrc-common which
I've tried toggling.  I get a reflector.log in /root:

03/10/05 14:54:49 + Closing client connection 127.0.0.1

I can't figure out what I did to break this and i've tried reinstalling TT.

any ideas?

Thanks,
Peter
