Question #209122 on Epoptes changed: https://answers.launchpad.net/epoptes/+question/209122 Alkis Georgopoulos proposed the following answer: Sure, no problem, but please also try this: $ sudo gedit /usr/share/pyshared/epoptes/ui/gui.py And change line 299 to: self.vncserver = subprocess.Popen(['x11vnc', '-noshm', '-nopw', '-threads', In a couple of weeks a new epoptes version will be published that (among other things) will enable threads support in x11vnc. This will make broadcasting faster, but it might also help in your case. -- You received this question notification because you are a member of Epoptes Developers, which is an answer contact for Epoptes. -- Mailing list: https://launchpad.net/~epoptes Post to : epoptes@lists.launchpad.net Unsubscribe : https://launchpad.net/~epoptes More help : https://help.launchpad.net/ListHelp

Question #209122 on Epoptes changed: https://answers.launchpad.net/epoptes/+question/209122 Alkis Georgopoulos proposed the following answer: What are your server specs? Maybe it's a bit slow and it can't receive many simultaneous client connections if they all come within 0.5 sec? Let's try to increase that to 1 sec instead: sleep 2.$(($(hexdump -e \%d\ -n 2 /dev/urandom) % 100)) ...I also wonder if it's related to DNS issues... -- You received this question notification because you are a member of Epoptes Developers, which is an answer contact for Epoptes. -- Mailing list: https://launchpad.net/~epoptes Post to : epoptes@lists.launchpad.net Unsubscribe : https://launchpad.net/~epoptes More help : https://help.launchpad.net/ListHelp

[Epoptes] [Question #209122]: Cannot broadcast to clients from a thin client
New question #209122 on Epoptes: https://answers.launchpad.net/epoptes/+question/209122 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? -- You received this question notification because you are a member of Epoptes Developers, which is an answer contact for Epoptes. -- Mailing list: https://launchpad.net/~epoptes Post to : epoptes@lists.launchpad.net Unsubscribe : https://launchpad.net/~epoptes More help : https://help.launchpad.net/ListHelp
