NetworkManager attempts to keep an active network connection available at all times.

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. In effect, the goal of NetworkManager is to make networking Just Work.

If you have special needs, we'd like to hear about them, but understand that NetworkManager is not intended to serve the needs of all users.

NetworkManager is composed of two parts:

  1. A daemon running as root (network-manager).

  2. A front-end (network-manager-gnome or network-manager-kde).

NetworkManager will only handle interfaces not declared in /etc/network/interfaces (see README file).


The features of NetworkManager are described on its homepage.


Make sure you read the fine manual:

NetworkManager in Squeeze

Wired Networks is Unmanaged

Un-managed devices means that Network-manager don't handles those devices. This occurs when two conditions are met:

The file /etc/network/interfaces contains anything about the interface, even:

And /etc/NetworkManager/nm-system-settings.conf contains: [main] plugins=ifupdown,keyfile

[ifupdown] managed=false }}}

"Auto Ethernet" and "Auto eth0"


Q. How do I configure a static IP address (for a server, etc) ?

A) Configure /etc/network/interfaces.

Q. Why can't I see NetworkManager with my new user account ?

A) Make sure human users are in the netdev group (see /usr/share/doc/network-manager-gnome/README.Debian).
