![]() For Wi-Fi interfaces, a hotspot functionality is provided which uses the same functionality besides setting up an ad-hoc WiFi network. Finally, use that profile for the network interface connected to the shared network. This hides all the complexity (dnsmasq, iptables, sysctl). Then use nm-connection-editor and setup a new profile using "shared to other computer" as the method for IPv4 (not possible from Gnome3's gnome-control-center). How to setup a connection sharing ("hotspot") for a wired interface ?Ī) First make sure to install dnsmasq-base (but not dnsmasq unless you disable the system daemon in /etc/default/dnsmasq). Why can't I see NetworkManager with my new user account ?Ī) Make sure human users are in the netdev group (see /usr/share/doc/network-manager-gnome/README.Debian). For the long answer see the corresponding entry in NetworkConfiguration. How can I configure DNS for NetworkManager?Ī) The short answer is to use nm-connection-editor. How do I configure a static IP address (for a server, etc) ?Ī) Use nm-connection-editor or configure /etc/network/interfaces as described in NetworkConfiguration. ![]() Set managed=true in /etc/NetworkManager/nf.Īuto Ethernet means "Select an Ethernet interface automatically"Īuto eth0 means "autoconfigure the eth0 interface".įAQ Q. If you want NetworkManager to handle interfaces that are enabled in /etc/network/interfaces: The file /etc/network/interfaces contains anything about the interface, even:Īnd /etc/NetworkManager/nf contains: Unmanaged devices means NetworkManager doesn't handle those network devices. usr/share/doc/network-manager/README ( online) and /usr/share/doc/network-manager/README.Debian ( online)Īs of Debian 6.0 "Squeeze", NetworkManager does not manage any interface defined in /etc/network/interfaces by default. The features of NetworkManager are described on its homepage. Starting with Debian 11 (bullseye), use: sudo service NetworkManager restart They can be edited (as root) using a text editor or the nm-connection-editor (enclosed in network-manager-gnome).įor changes in configuration to become effective, you may have to restart the NetworkManager daemon: For options in these files refer to the manpage on nm-settings: man nm-settings or online. Those are stored at /etc/NetworkManager/system-connections/. NetworkManager keeps connection information on known individual networks in configuration files called profiles. NetworkManager will only handle interfaces not declared in /etc/network/interfaces (see README file). NetworkManager is composed of two layers:Ī daemon running as root: network-manager.Ī front-end: nmcli and nmtui (enclosed in package network-manager), nm-tray, network-manager-gnome (nm-applet), plasma-nm.Īdditionally, there are various plugins available that enable NetworkManager to handle other, special connections like different types of VPN connections. It still may be used.Īnother way to configure: leverage on Systemd Details are described in NetworkConfiguration. workstation), the regular way to configure the network was using interfaces configuration file at /etc/network/interfaces. If you have special needs, the upstream's developers would like to hear about them, but understand that NetworkManager is not intended to serve the needs of all users.įor basic or simple configurations (e.g. Whilst it was originally targeted at desktops, it has more recently been chosen as the default network management software for some non-Debian server-oriented Linux distributions. In effect, the goal of NetworkManager is to make networking Just Work. If using DHCP, NetworkManager is intended to replace default routes, obtain IP addresses from a DHCP server and change nameservers whenever it sees fit. The point of NetworkManager is to make networking configuration and setup as painless and automatic as possible. NetworkManager attempts to keep an active network connection available at all times.
