NetworkManager is the standard Linux network configuration tool suite. NetworkManager supports both wireless daemons i.e iwd and wpa_supplicant. Using both may lead to conflicts.
Installation
# apk add networkmanager
# setup-devd udev
There are multiple interfaces available for NetworkManager:
- TUI: networkmanager-tui, a curses-based interface (run
nmtui) - Command line: networkmanager-cli (run
nmcli) - GUI: plasma-nm for Plasma integration and applet
- GUI: network-manager-applet for a GTK system tray applet
For the list of all NetworkManager packages refer networkmanager-*
You will need to install an additional package if you want NetworkManager to connect to wifi:
# apk add networkmanager-wifi
After installation start NetworkManager:
# rc-service networkmanager start
Then set it to autostart the service on boot:
# rc-update add networkmanager default
Also your user needs to be in the plugdev group:
# adduser <YourUsername> plugdev
Wired networks
If wired networks do not appear or you get an error message like "Could not activate connection: Connection 'Ethernet connection 1' is not available on device eth0 because device is strictly unmanaged", add the following to /etc/NetworkManager/NetworkManager.conf:
Contents of /etc/NetworkManager/NetworkManager.conf
Wireless networks
wpa_supplicant backend
Refer the sections wpa supplicant and Automatic Configuration on System Boot. wpa_supplicant configuration might not be required, if it isn't it may be a good idea to have it setup just as a fallback.
Now open /etc/NetworkManager/NetworkManager.conf in a text editor and change it to something like this:
Contents of /etc/NetworkManager/NetworkManager.conf
Now you need to stop conflicting services:
# rc-service networking stop
# rc-service wpa_supplicant stop
Now restart NetworkManager:
# rc-service networkmanager restart
Now connect to a network using one of the interfaces mentioned in Installation
If that connects and stays connected with no issues enable the networkmanager service and disable the networking and wpa_supplicant boot services:
# rc-update add networkmanager
# rc-update del networking boot
# rc-update del wpa_supplicant boot
iwd backend
NetworkManager supports wireless networks through iwd, however, consider existing issues before using it. After installation, enable the server and restart NetworkManager:
rc-service iwd start rc-service networkmanager restart
To use iwd though, you've have to edit NetworkManager's configuration because it still defaults to wpa_supplicant instead. Add the following to /etc/NetworkManager/NetworkManager.conf:
[device] wifi.backend=iwd
VPN support
Since version 1.16, NetworkManager has support for Wireguard[1].
Support for other VPN types is provided by plugins. They are provided in the following packages:
- networkmanager-openvpn for OpenVPN
Troubleshooting
nm-applet not authorized to control networking
You can enable all users to edit connections without adding polkit.
First, make the conf.d directory for networkmanager:
# mkdir -p /etc/NetworkManager/conf.d
Then, add following content to /etc/NetworkManager/conf.d/any-user.conf:
[main] auth-polkit=false
Finally, restart networkmanager:
# rc-service networkmanager restart
