Ditching NetworkManager

[Haringstad]

I know, I know....

 

I am trying to do the following:

• apt-get autoremove --purge network-manager rdnssd
• ifdown eth0
• ifdown wlan0
• remove all settings in /etc/network/interfaces, except for the lo interface.

Configure systemd-networkd

• rm /etc/resolv.conf ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
• vim /etc/systemd/network/wired.network

[Match] 
Name=eth0 

[Network] 
DHCP=both 

[DHCP] 
RouteMetric=10

 

• vim /etc/systemd/network/wireless.network

[Match] 
Name=wlan0 

[Network] 
DHCP=both 

[DHCP] 
RouteMetric=20

• Enable the services

systemctl enable systemd-resolved.service 
systemctl enable systemd-networkd.service 
systemctl start systemd-resolved.service 
systemctl start systemd-networkd.service

• Create a systemd service for your wlan interface:
• vim /etc/systemd/system/wpa_supplicant@wlan0.service

[Unit] 
Description=WPA supplicant for %i 

[Service] 
ExecStart=/sbin/wpa_supplicant -i%i -c/etc/wpa_supplicant/wpa_supplicant.conf 

[Install] 
WantedBy=multi-user.target

• vim /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev 

network={ 
	ssid="NW_TEST" 
    key_mgmt=NONE 
} 

network={ 
     ssid="DaHome" 
     psk="a very secret key indeed" 
}

• Enable the wpa_supplicant

systemctl stop wpa_supplicant 
systemctl disable wpa_supplicant 
systemctl enable wpa_supplicant@wlan0 
systemctl start wpa_supplicant@wlan0

This works fine on my orange-pi-win-plus. But on my other orange-pi systems, all running armbian, the eth0 interface doesn't come up after these actions. Only when I reinstate the /etc/network/interfaces file as is, it comes back to life. Very sadly, because to me, the systems feel more snappy when I use this config. SSH, resolving, all goes a lot faster. 

 

Does anyone have a clue on how to bring up the network interface(s), to use this setup?

 

Regards!

Use of the interfaces file is the current debian way for network configuration.  You are no longer using network-manager and have thus ditched it.

 

Have you checked systemd status and logs?  What do you find out?  Why are you trying to keep the interfaces file?  It is not used by networkd.  Might try getting just eth0 working with networkd and go from there.
