Thin Client Manager problems

[David Van Assche]

Hi,
   I'm having some trouble running Fl_Teachertool on Gutsy. When
Fl_Teachertool starts up I get a dialogue saying no users connected,
which isn't true. I've tried grepping with the command specified:

ps eaxww|grep "bash --login -c"|grep "LTSP_CLIENT"|grep PPID|grep -v grep

and get nothing. Tried with sudo as well, same result.

I'm assuming something must have changed in Gutsy as to how users are
detected, but its a shame because my teachers started using this a lot
and were praising it to high heaven. Now we're a bit stuck using tcm,
which leaves a lot to be desired.

Any help to get it to work would be much appreciated.

Kind Regards,
David Van Assche
