How-to set static ip in ubuntu

90

Setting a static IP in Ubuntu involves editing the netplan configuration file using the nano text editor. Here’s a brief summary of the steps:

1. Open the terminal and run the following command to install the nano text editor if it’s not already installed:

   sudo apt install nano

2. Next, navigate to the netplan configuration directory by running:

   cd /etc/netplan

3. Use the nano text editor to open the netplan configuration file. For example, if the file is named “01-netcfg.yaml”, run:

   sudo nano 01-netcfg.yaml

4. Within the file, locate the network interface you want to set a static IP for. It will look similar to this:

   network:
     version: 2
     renderer: networkd
     ethernets:
       enp0s3:
         dhcp4: yes

5. Replace the line dhcp4: yes with the following lines to set a static IP:

   addresses: [192.168.1.100/24]
   gateway4: 192.168.1.1
   nameservers:
     addresses: [8.8.8.8, 8.8.4.4]

Make sure to adjust the IP address, subnet mask, gateway, and DNS servers according to your network configuration.

6. Save the changes by pressing “Ctrl + O”, then exit nano by pressing “Ctrl + X”.
7. To apply the changes, run the following command in the terminal:

   sudo netplan apply

After following these steps, your Ubuntu system should now have a static IP address configured. Keep in mind that any mistakes in the netplan configuration file can cause network connectivity issues, so it’s important to double-check your changes before applying them.
