kadkarol,

The client with IP 192.168.0.223 doesn't have the correct server's
certificate.

If this is an ltsp client, please make sure you have correctly followed
the instructions in http://www.epoptes.org/installation (execute
epoptes-client -c in your chroot and ensure that it doesn't throw any
errors, and then execute ltsp-update-image outside the chroot.)

If it's a standalone client, execute epoptes-client -c or transfer the
server.crt manually.

Of course epoptes shouldn't crash when there is a client with a wrong
certificate, so this is a bug...

** Changed in: epoptes
   Importance: Undecided => Medium

** Changed in: epoptes
       Status: Incomplete => Confirmed

** Summary changed:

- I can not preview the user's screen in ubuntu ltsp environment
+ Epoptes crashes when a client with an invalid server's certificate connects

Title:
  Epoptes crashes when a client with an invalid server's certificate
  connects

Status in Epoptes:
  Confirmed

Bug description:
  After launching epoptes I see a preview screen, the user, but only 1
  maybe 2 times. Then do not. In the console I have the information:

  New connection from 192.168.0.223:36473
  Disconnect from 192.168.0.223:36473

  Strange, because the computers in the network have addresses 192.168.0.x, and the errors in the console 127.xxx
  As if epoptes lose connection with their customers. When you click on the icon of customer information is not displayed if no information
