How to configure Epoptes in Edubuntu 12.04 to work with thin clients?

Asked by Thomas Richards

I am new to Linux. I do not know much. but I have been give the task to see how this software works. I have been unsuccessful in getting the clients to appear in this software. I have entered a user in to epoptes file and logged out and in. But, It does not seem to work. I thought that the uninstalling and reinstalling would help. No, That didn't work. What other things do I need to do to this software to make it work? I have followed the steps of installing it to a Tee. I know I am not giving much details, like I said I am very new to this.

ps. this software did come with the edubuntu 12.04 installed.

Hi Thomas,

Press Alt+F2 and type gnome-terminal, to open a console. This makes it easy to give us precise feedback, so that we see what is missing from your setup.
There, maximize the window, enter the following commands, and paste their whole output here.

dpkg-query -W ltsp-server epoptes epoptes-client
grep -v ^# /etc/default/epoptes*
grep server /etc/hosts
md5sum /etc/epoptes/server.crt /opt/ltsp/i386/etc/epoptes/server.crt
id -Gn

If you are using LTSP, you only need to give us the output of those commands as executed on the LTSP server.
If you are not using LTSP (or if you don't even know what that is), then you're supposed to have epoptes installed in one "server" PC, and epoptes-client installed in many "client" PCs. In that case we need you to give us the output of those commands on the "server" and on one of your "clients".

First of all, if you do this:
1) login as trichards38 and open epoptes
2) login as _another_ user from another thin client
...then you can see that user/client in epoptes, right?

To additionally see the clients before login, you need to install epoptes-client in your chroot, and fetch the server certificate, as mentioned in the http://www.epoptes.org/installation page, under the paragraph named "Client package installation for LTSP chroots".

Follow the instructions in that paragraph, and mention if you have any problems with them.
To verify that you did it right, this command:
md5sum /etc/epoptes/server.crt /opt/ltsp/i386/etc/epoptes/server.crt
....shouldn't reply that it cannot find the file:
md5sum: /opt/ltsp/i386/etc/epoptes/server.crt: No such file or directory

Can you help with this problem?
