/etc/netplan/00-installer-config.yaml

[micnorden]

Ahoi... habe mir einen neuen Server geleistet und versuche gerade dieses Tutorial anzuwenden: https://www.howtoforge.com/tutorial/ubuntu-20.04-focal-fossa-server/
wenn ich den File: /etc/netplan/00-installer-config.yaml bearbeite geht sofort der Server down...

das ist der Inhalt vom originalen File nach der automatischen Installation von Ubuntu 20.x

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s20f0:
      dhcp4: yes

Dann ergänze ich den File mit meinen Daten:

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s20f0:
      dhcp4: no
      dhcp6: no
      addresses: [51.15.x.xxx/32]
      gateway4: 51.15.x.x
      nameservers:
        addresses: [199.167.66.107,104.37.178.107,199.167.66.108,104.37.178.108]

netplan generate

funktioniert noch aber sobald ich:

netplan apply

eingebe ist der server down und ich kann von vorne starten...

was mache ich falsch???

addresses: [51.15.x.xxx/24]

das funktioniert... dann läuft auch:

sudo netplan generate
sudo netplan apply

aber dann habe ich:

vermutlich hast du vergessen, die routen anzugeben...
routes:
- to: 0.0.0.0/0 #Standardroute für IPv4
via: gateway4IP

Ahoi habe das jetzt hin bekommen:

      nameservers:
        addresses: [199.167.66.107,104.37.178.107,199.167.66.108,104.37.178.108]

nachdem ich die Nameserver von EuroDNS gelöscht habe:

     nameservers:
       addresses: [8.8.8.8,8.8.4.4]

und die 2 freien Nameserver von Google eingesetzt habe läuft das...
