Ubuntu 18.04 Netplan!

by

This was unexpected, but I think I’m coping well. These are my notes on configuring netplan networking on my Ubuntu 18.04 server.

  1. systemctl disable NetworkManager.service NetworkManager-wait-online.service
  2. systemctl mask NetworkManager-wait-online.service
  3. systemctl daemon-reload
  4. apt install bridge-utils -y
  5. edit /etc/udev/rules.d/70-net.rules 
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="c8:70:00:9f:d7:72", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:e2:ed:17:09:60", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:e2:ed:17:09:61", NAME="eth2"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:e2:ed:17:09:62", NAME="eth3"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:e2:ed:17:09:63", NAME="eth4"
  6. edit /etc/netplan/01-netcfg.yaml 
      version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: no
      dhcp6: no
    eth1:
      dhcp4: no
      dhcp6: no
    eth2:
      dhcp4: no
      dhcp6: no
    eth3:
      dhcp4: no
      dhcp6: no
    eth4:
      dhcp4: no
      dhcp6: no
  bridges:
    br0:
      dhcp4: yes
      dhcp6: no
      interfaces:
         - eth0
      routes:
         -  to: 192.168.100.0/24
            via: 192.168.45.3
            on-link: true
    br1:
      dhcp4: no
      dhcp6: no
      addresses: [10.45.0.1/24]
      interfaces:
         - eth1
    br2:
      dhcp4: no
      dhcp6: no
      addresses: [10.45.1.1/24]
      interfaces:
         - eth2
    br3:
      dhcp4: no
      dhcp6: no
      addresses: [10.45.2.1/24]
      interfaces:
         - eth3
    br4:
      dhcp4: no
      dhcp6: no
      addresses: [10.45.3.1/24]
      interfaces:
         - eth4
  7. sudo netplan generate
  8. sudo netplan apply
  9. reboot

Without my eth1-eth4 devices plugged into a switch, rebooting takes forever.
