Networking

TeamSBC uses systemd-networkd for network configuration instead of NetworkManager. Network configuration files are placed in /etc/systemd/network/.

Checking network status

$ networkctl

For detailed information about a specific interface:

$ networkctl status eth0

Wired networking

A default configuration for wired networking using DHCP is provided out of the box. To configure a static IP address create a .network file in /etc/systemd/network/:

[Match]
Name=eth0

[Network]
Address=192.168.1.100/24
Gateway=192.168.1.1
DNS=192.168.1.1

After creating or modifying network configuration files restart systemd-networkd:

$ run0 systemctl restart systemd-networkd.service

Wi-Fi

Wi-Fi is managed through wpa_supplicant alongside systemd-networkd.

Connecting to a network

Create a wpa_supplicant configuration for your wireless interface:

$ run0 wpa_passphrase "MyNetwork" "MyPassword" > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

Enable and start the wpa_supplicant service for your interface:

$ run0 systemctl enable --now wpa_supplicant@wlan0.service

Then create a .network file in /etc/systemd/network/ for the wireless interface:

[Match]
Name=wlan0

[Network]
DHCP=yes

DNS

DNS is handled by systemd-resolved. You can check the current DNS configuration with:

$ resolvectl status
