Hi Wolfgang,

I tried Epoptes. It works rather well and gives the teacher a number of
helpful tools.

However, I wasn?t able to make any of the screen broadcasting tools work.
Does it work at your end?

I?m not very comfortable with the fact that a teacher has access to all
thin clients on both subnets. If chroot is epoptes enabled then he has
access to diskless workstations as well enabling him to monitor all LTSP
clients in the system without any user knowing about it.

Is this not a security issue?

Kind regards,
Roman
