# Epoptes server will use the following group for the communications socket.
# That means that any user in that group will be able to launch the epoptes UI
# and control the clients.
# The server which epoptes-client will be connecting to.
# If unset, thin client user sessions running on the server will try to connect
# to "localhost", while thin client root sessions and fat or standalone clients
# will try to connect to "server".
# LTSP automatically puts "server" in /etc/hosts for thin and fat clients,
# but you'd need to put "server" in DNS manually for standalone clients.
