Systemd does not have native wifi support. To the following with walk you through configuring WPA and EAP wifi modes. While WiFi is not something you would commonly configure Ubuntu server for, it it is prevalent enough you may consider using it in some use cases.
To update your netplan configurations, run the netplan apply command. To enabled just one, you would remove the network IP version not needed.
The following example shows how to enable DHCP for both IPv4 and IPv6. sudo netplan apply How to set DHCP Addressesĭynamically addressed can be assigned for IPv4 and IPv6, provided your network has a DHCP server. To apply changes to netplan you will need to reload your Netplan network configurations. We’ll cover DNS a little further down in this tutorial. The interface’s name is en01 and it has been assigned static IP addresses 192.168.1.25/24 for IPv4, and 2001:1::1/64 for IPv6.Īs both IPv4 and IPv6 have been assigned static IP addresses, each has a gateway set too.ĭNS Name servers are also defined in this file. The following is an example Netplan file with a network interface that has a static IP address. sudo nano /etc/netplan/00-install-config.yaml How to Set Static IP Address
sudo vi /etc/netplan/00-installer-config.yamlĪlternatively, a simpler text editor by the name of nano can be used instead of vim. To edit the default netplan file, use the following command.
The default file networking interfaces for a new Ubuntu 20.04 install is /etc/netplan/00-installer-config.yaml. Network interfaces in Ubuntu 20.04 are configured in NetPlan YAML files, which are stored under /etc/netplan. Introduced back in 18.04, April 2018, networking was redone using a new system called Netplan – a YAML based configuration network configuration system for NetworkManager and SystemD. You will learn how to set static IP addresses, DHCP addresses, as well as how to configure DNS and Wifi. In this tutorial, you will learn how to configure networking in Ubuntu 20.04 with Netplan.
