Is that possible for debian users to connect to network through systemd-networkd?

Systemd offers the ability to manage the network by itself without additional tools such as netctl or NetworkManager. I am running debian 8 and i need to configure my network using systemd-networkd

What are the requirement to manage the networks under debian jessie through systemd-networkd? And how to enable services and network?

Method 1

To connect to network through systemd-networkd you need to create some configuration files:

For wireless connections create wireless.network file with the following content:

nano /etc/systemd/wireless.network:

Match]
Name=wlan0

[Network]
DHCP=ipv4
DNS=8.8.8.8
DNS=8.8.4.4

[DHCP]
RouteMetric=20

For wired connections create wired.network file with the following content:

nano /etc/systemd/network/wired.network :

[Match]
Name=eth0

[Network]
DHCP=ipv4
DNS=8.8.8.8
DNS=8.8.4.4

[DHCP]
RouteMetric=10

For wireless connections, create a configuration file for your access point by using:

sudo -i
echo "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=sudo" > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
wpa_passphrase SSID password >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

exit

disable network-manager:

sudo systemctl disable NetworkManager

Enable systemd-networkd :

sudo systemctl enable systemd-networkd

Enable the systemd-resolved :

sudo systemctl enable systemd-resolved
sudo systemctl start systemd-resolved

delete or rename resolv.conf then create a symlink to /etc/resolv.conf:

sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

Restart the srvice:

systemctl restart systemd-networkd

Reboot

Type the following command
