Ubuntu 17.10 network configuration is completely changed. Have you heard of NetPlan? Probably not, but if you have, then you’re a step ahead of many. NetPlan is a new network configuration tool introduced in Ubuntu 17.10 to manage network settings.
It can be used by writing a simple YAML description of the required network interfaces with what they should be configured to do; and it will generate the required configuration for a chosen renderer tool.
This new tool replaces the static interfaces (/etc/network/interfaces) file that had previously been used to configure Ubuntu network interfaces. Now you must use /etc/netplan/*.yaml to configure Ubuntu interfaces.
This brief tutorial is going to show students and new users how to use NetPlan to set a static IP address on Ubuntu servers. This should be easy and quick.
The new interfaces configuration file now live in the /etc/netplan directory. A file called 01-netcfg.yaml is used to configured the first interface. Below is the default configuration for a interface using DHCP.
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: ens33: dhcp4: yes dhcp6: yes
To save your changes, you run the commands below.
sudo netplan apply
Configuring Static IP Addresses
To configure a static IP address using the new NetPlan tool, the file should look like this: IPv4 address (192.168.1.2), Gateway (192.168.1.1), DNS Servers (8.8.8.8,8.8.4.4)
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: ens33: dhcp4: no dhcp6: no addresses: [192.168.1.2/24] gateway4: 192.168.1.1 nameservers: addresses: [8.8.8.8,8.8.4.4]
Exit and save your changes by running the commands below
sudo netplan apply
You can add IPv6 addresses line, separated by a comma.. example below.
# This file describes the network interfaces available on your system # For more information, see netplan(5). network: version: 2 renderer: networkd ethernets: ens33: dhcp4: no dhcp6: no addresses: [192.168.1.2/24, '2001:1::2/64'] gateway4: 192.168.1.1 nameservers: addresses: [8.8.8.8,8.8.4.4]
Save your changes, apply and you’re done.
This is how to set static IP addresses on Ubuntu 17.10.
