Epoptes

Problem with broadcast

Asked by Olivier Péault

Hello
I'm using epoptes in a classroom with 16 standalone clients.
All is working fine except that I can't broadcast my screen to any client : it does nothing.
When I launch epoptes from a terminal and try to broadcast, I get the following message :

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/epoptes/ui/gui.py", line 287, in broadcastScreen
    self._broadcastScreen('true')
  File "/usr/lib/python2.7/dist-packages/epoptes/ui/gui.py", line 271, in _broadcastScreen
    subprocess.call(['x11vnc', '-storepasswd', pwd, pwdfile])
  File "/usr/lib/python2.7/subprocess.py", line 493, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
    raise child_exception
OSError: [Errno 2] Aucun fichier ou dossier de ce type

Is there anything I can do ?
Thank you in advance

Hello Olivier,

We have probably left x11vnc out of the epoptes dependencies. Installing x11vnc in the PC that epoptes is installed should fix the problem.

epoptes recommends epoptes-client, which depends on x11vnc.
You probably installed with --no-install-recommends

When installing with --no-install-recommends, you're missing some functionality, provided by x11vnc on the server and openssl/xterm on the clients. The part of "which functionality should one lose when installing with --no-install-recommends" might need some work (and it will change in the future when epoptes will also have a command-line tool), but if one doesn't want to lose any functionality at all, then he should definately NOT use --no-install-recommends.
