Hi, since yesterday the network on my buster system all of a sudden refuses to work. I am using systemd, no network-manager is running. The /etc/network/interfaces file looks (as it did before) like:
auto lo iface lo inet loopback allow-hotplug enp2s0 iface enp2s0 inet dhcp With ifconfig the enp2s0 interface appears to be up, the line that should look similar to inet 192.168.178.33 netmask 255.255.255.0 broadcast 192.168.178.255 misses, though. Trying `ifdown enp2s0` the command seems to never return. I suspected udev to have for some reason changed the interface name; some sources I found suggest to look at /etc/udev/rules.d/70-persistent-net.rules but there is nothing in that file that is not commented out, so I guess that this mechanism may be outdated. The output of `systemctl status networking.service` looks like this: ● networking.service - Raise network interfaces Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled) Active: active (exited) since Mon 2021-07-12 10:40:20 CEST; 1h 27min ago Docs: man:interfaces(5) Process: 7545 ExecStart=/sbin/ifup -a --read-environment (code=exited, status=0/SUCCESS) Main PID: 7545 (code=exited, status=0/SUCCESS) Jul 12 10:40:19 miniac systemd[1]: Starting Raise network interfaces... Jul 12 10:40:20 miniac systemd[1]: Started Raise network interfaces. I a not sure what to make of all this, does anyone have a clue what else I might try? Thanks in advance Michael
