Arch Linux - How to Install systemd Network Manager

The package systemd is part of the default Arch installation.

systemctl enable systemd-networkd.service
Created symlink /etc/systemd/system/dbus-org.freedesktop.network1.service → /usr/lib/systemd/system/systemd-networkd.service.
Created symlink /etc/systemd/system/multi-user.target.wants/systemd-networkd.service → /usr/lib/systemd/system/systemd-networkd.service.
Created symlink /etc/systemd/system/sockets.target.wants/systemd-networkd.socket → /usr/lib/systemd/system/systemd-networkd.socket.
Created symlink /etc/systemd/system/network-online.target.wants/systemd-networkd-wait-online.service → /usr/lib/systemd/system/systemd-networkd-wait-online.service.

Let's change the configuration for our wired adapter using a static IP.

[Match]
Name=ens18

[Network]
Address=192.168.45.5/24
Gateway=192.168.45.1
DNS=192.168.45.1
/etc/systemd/network/20-wired.network

Systemd also has a module for DNS and it will pick the DNS servers set in our /etc/resolv.conf. Let's edit it as seen below :

# Generated by NetworkManager
search localdomain
nameserver 192.168.45.1
/etc/resolv.conf

We need to enable and start the systemd DNS resolver as donethe systemd network manager.

systemctl enable systemd-resolved.service
systemctl start systemd-resolved.service
systemctl start systemd-networkd.service
[root@docker0 ~]# ip -c addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet6 fe80::6005:a9ff:fecb:94d1/64 scope link 
       valid_lft forever preferred_lft forever
