Binary package “network-manager-config-connectivity-debian” in ubuntu artful

NetworkManager configuration to enable connectivity checking

 This package contains a configuration file which enables NetworkManager's
 connectivity checking functionality.
 NetworkManager will try to connect to a Debian server to determine the
 connection status.
 This is particularly useful for captive portal detection.
 No user data is transmitted in the connectivity checks, but merely contacting
 the Debian connectivity check servers reveals that the user is running a
 Debian(-based) operating system with NetworkManager.
