Ethernet Connection and IP Device Communication: Netplan Configuration with Hardcoded IP
In this article, we will discuss the configuration of an Ethernet connection for IP device communication using Netplan, a network configuration tool for Linux systems. Specifically, we will focus on setting up a hardcoded IP address for the device.
Understanding Ethernet and IP Device Communication
Ethernet is a widely used networking technology that allows devices to communicate with each other over a wired connection. In order for devices to communicate, they must have an IP address, which serves as a unique identifier on the network. IP addresses can be assigned dynamically using protocols such as DHCP, or they can be hardcoded into the device's network configuration.
Setting up a Hardcoded IP Address with Netplan
Netplan is a network configuration tool for Linux systems that uses a simple YAML syntax to define network configurations. To set up a hardcoded IP address for an Ethernet connection using Netplan, you will need to create a configuration file and define the network interface, IP address, and other relevant settings.
Creating the Netplan Configuration File
The first step in setting up a hardcoded IP address with Netplan is to create a configuration file. This file should be placed in the /etc/netplan directory and should have a .yaml file extension. For example, you might name the file 01-netcfg.yaml.
Once you have created the configuration file, you will need to define the network interface and IP address. This is done using the network: and version: keywords, followed by the interface name and IP address, as shown in the following example:
network:
version: 2
ethernets:
enp0s3:
dhcp4: no
addresses: [169.254.241.1/24]In this example, the interface name is enp0s3 and the IP address is 169.254.241.1/24. The /24 at the end of the IP address specifies the subnet mask, which in this case is 255.255.255.0.
Applying the Netplan Configuration
Once you have created the Netplan configuration file, you can apply the changes by running the following command:
sudo netplan applyThis will activate the new network configuration and assign the hardcoded IP address to the Ethernet connection.
