No thumbnails of fat client

[kadkarol]

My system lubuntu 14.04, Epoptes 0.5.7, Environment ltsp-pnp
I not see thumbnail in epoptes.

Maybe the reason is that it can not transfer certificate
in temrinal:
zsceglow@zsceglow-ltsp:~$ sudo epoptes-client -c
[sudo] password for zsceglow:
connect: Connection timed out
connect:errno=110

On the server, run:
$ sudo md5sum /etc/epoptes/*
$ sudo netstat -nap|grep 789

On the fat client, run:
$ md5sum /etc/epoptes/*
$ getent hosts server

Paste the output of all those commands here.

I'm converting the bug report into a question, as it's not a bug in the application but a user error.

The problem is that the /etc/epoptes/server.crt file is empty, of size zero.
That might have happened if you ran `sudo epoptes-client -c localhost` on the server instead of some chroot.
You don't need to run `epoptes-client -c` at all, in ltsp-pnp.

EITHER see: http://www.epoptes.org/installation#TOC-Manually-updating-the-OpenSSL-certificate for how to create a new certificate.
OR run: sudo apt-get purge epoptes; sudo apt-get install epoptes
(don't do both of them)

Then run `sudo ltsp-update-image -c /`, then reboot the clients.
