Red Hat initiated a NetworkManager project in 2004 with the goal of enabling Linux users to deal more easily with modern networking needs, particularly wireless networking. NetworkManager takes an opportunistic approach to network selection, attempting to use the best available connection as outages occur, or as the user roams between wireless networks. It prefers Ethernet connections over “known” wireless networks, which are preferred over wireless networks with SSIDs to which the user has never connected. The user is prompted for WEP or WPA keys as needed.
NetworkManager has two components:
- a service which manages connections and reports network changes
- a graphical desktop applet which allows the user to manipulate network connections. The nmcli applet provides similar functionality on the command line.
Both components are intended by the developers to be reasonably portable, and the applet is available to desktop environments which implement the Freedesktop.org System Tray Protocol, including GNOME, KDE Plasma Workspaces, Enlightenment (window manager) and Xfce. As the components communicate via D-Bus, applications can be written to be “link-aware”, or to replace the provided applet entirely. One example is KNetworkManager, a KDE frontend to NetworkManager developed by Novell for SUSE Linux.
Mobile broadband configuration assistant
Antti Kaijanmäki announced the development of a mobile broadband configuration assistant for NetworkManager in April 2008 it became available in NetworkManager version 0.7.0. Together with the package mobile-broadband-provider-info the connection is easily configured.
