=== Wired Networks is Unmanaged ===
 {i} This ''problem'' is very likely to occur to people who upgrade to Squeeze, see DebianBug:530024 .

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:
 {{{
allow-hotplug eth0
iface eth0 inet dhcp
}}}

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

[ifupdown]
managed=false
}}}
 * Comment the lines in /etc/network/interfaces I you want to have Lenny behavior. <<BR>> ''or''
 * Set {{{managed=true}}} in {{{nm-system-settings.conf}}} if you want network-manager to handle interfaces that are declared in {{{/etc/network/interfaces}}} (you need to kill {{{nm-system-settings}}}

NetworkManager

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).

Features

The features of NetworkManager are described on its homepage.

  • {i} This problem is very likely to occur to people who upgrade to Squeeze, see 530024 .

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: 

  • allow-hotplug eth0

  • Comment the lines in /etc/network/interfaces I you want to have Lenny behavior.
    or

  • Set managed=true in nm-system-settings.conf if you want network-manager to handle interfaces that are declared in /etc/network/interfaces (you need to kill nm-system-settings

FAQ

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

A) Configure /etc/network/interfaces.
