If i start epoptes directly from the server all works fine, but if I start it from a thin client I've some issues sharing screen.
If I start all lab clients and i try to share desktop /Before/ logging in, some clients works, some shows the message:

VNC Viewer: Information....  "unable to connect to host: Connection refused (111)" 

if I change from "sharing fullscreen" to "sharing in window" I've the same issue, but not on the same clients. I'm not able to understand if there's a "rule" on which clients work or not, or if it's a random issue.
if i stop desktop sharing, the error message automatically disappears, f i restart it, the number of thin clients that are able to connect to the teacher's one is rapidly decreasing.

teachers that starts epoptes are all ldap users, if it could be relevant. I'll test ASAP with a local user, but for now the lab is in use, so I cannot try.

if i run epoptes-client in "root terminal, locally" or "user terminal" it says
*epoptes-client connecting to server:789...
...done

the error is still there.

any suggestion?
