Network Manager的应用介绍

network management framework (GNOME frontend)

NetworkManager attempts to keep an active network connection available at all
times. It is intended only for the desktop use-case, and is not intended for
usage on servers. The point of NetworkManager is to make networking
configuration and setup as painless and automatic as possible. If using DHCP,
NetworkManager is _intended_ to replace default routes, obtain IP addresses
from a DHCP server, and change nameservers whenever it sees fit.

This package contains a systray applet for GNOME's notification area but it
also works for other desktop environments which provide a systray like KDE
or XFCE.
It displays the available networks and allows to easily switch between them.
For encrypted networks it will prompt the user for the key/passphrase and it
can optionally store them in the gnome-keyring.
