| Q. How to setup a connection sharing ? :: First make sure to install dnsmasq-base (but not dnsmasq unless you disable the system daemon in /etc/default/dnsmasq). Then use nm-connection-editor and setup a new profile using "shared to other computer" as the method for IPv4. This hides all the complexity (dnsmasq, iptables, sysctl).
NetworkManager attempts to keep an active network connection available at all times.
NetworkManager is composed of two parts:
A daemon running as root (network-manager).
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:
interfaces(5) man page
Wired Networks are Unmanaged
As of Debian 6.0 "Squeeze", NetworkManager does not manage any interface defined in /etc/network/interfaces by default.
Unmanaged devices means NetworkManager doesn't handle those network 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/NetworkManager.conf contains:
[main] plugins=ifupdown,keyfile [ifupdown] managed=false
Enabling Interface Management
If you want NetworkManager to handle interfaces that are enabled in /etc/network/interfaces:
Set managed=true in /etc/NetworkManager/NetworkManager.conf.
"Auto Ethernet" and "Auto eth0"
Auto Ethernet means "Select an Ethernet interface automatically"
Auto eth0 means "autoconfigure the eth0 interface".
- Q. How do I configure a static IP address (for a server, etc) ?
A) Use nm-connection-editor or configure /etc/network/interfaces as described in NetworkConfiguration.
- Q. How can I configure DNS for NetworkManager?
A) The short answer is to use nm-connection-editor. For the long answer see the corresponding entry in NetworkConfiguration.
- 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).
