Connect to clients yields 'twisted.protocols.amp.UnknownRemoteError'
I am running Edubuntu 11.10.
Is there a debug mode I can run or more detailed logs I can browse?
I launched via cli to capture any output, but there isn't much that looks useful (included below).
I have installed the client on an edubuntu thin client (ltsp server chroot) and the server on the edubuntu ltsp server per instructions on website. All of my permissions are correct; all of my ltsp-images have been updated; all of my thin clients have rebooted.
I log into a thin client using the username that I associated with the group epoptes and launch epoptes (via cli). The display shows me the thin clients that have booted (including the one that I am on). Most of the time, it shows nobody logged into any of them. One time, I was able to show a thin client with a username: "kidputer2 (hailey)" that also showed in the thumbnail display, a current screenshot.
When I try to "execute" a message, nothing happens (neither on the server nor client) and the cli spits out the error message:
ErrorCallback: [Failure instance: Traceback (failure with no frames): <class 'twisted.
]
This is a capture of a session where I could see a screenshot of the one client that had a logged in user:

I should also mention that one time when I clicked 'monitor student', I saw this on the cli (but nothing in either GUI):
