Errors 104 and 111

Asked by ale3andro

I have been using epoptes for quite a long time with great success but now I have a problem.
I can't broadcast my screen to the pc's in the computer lab.
I can lock and unclock client desktops, connect remotely and assist individuals but when I try to broadcast my screen in the clients a window pops up (in all clients) indicating erros. In some clients the error code is (104): "Connection reset by peer" and in some others the error code is (111): "Connection refused".
My server and clients are Ubuntu 13.04 (fat clients) and I don't use firewall (ufw) on the server. I can telnet from a client to server's port 5900 which means that the port is not blocked.
I have tried removing (purging) and installing epoptes and epoptes-client from the server but with no luck.
Any help would be appreciated.
Thank you.

Start epoptes from the command line, e.g. from gnome-terminal.
When broadcasting, you'll see a port number in the terminal.
Try to telnet to that, from the clients.
Or if you see any errors, paste them here.

It's not using 5900 in order to allow multiple teachers broadcasting from the same server to multiple classrooms in parallel (that's easily done with e.g. ltsp fat clients as the teacher PCs).

Ok my bad! After stopping ica (iTalc) everything works as it used too!
Thank you very much Alkis.
