Hi there. I'm having an issue with iTALC using Ubuntu on both my system and the clients. The error is as follows:

There seems to be no iTALC service running on this computer or the authentication-keys aren't set up properly. The service is required for running iTALC. Contact your administrator for solving this problem.

I have the exact same keys in both systems in /etc/italc/keys, and I changed the permissions so everybody can read.

Still, the issue persist. What can I do?
