Method 1: Configuring a Static IPv4 Address Using nmtui (Text User Interface)

The nmtui tool provides a simple interface to configure network settings.

Step 1: Launch nmtui

Open a terminal and type:

sudo nmtui

Step 2: Edit a Connection

• Select Edit a connection and press Enter.
• Choose the connection you want to configure (e.g., Wired connection 1).
• Press Enter.

Step 3: Static IPv4 Settings

• Set IPv4 Configuration to Manual.
• Enter your desired IP address, gateway, and DNS servers in the corresponding fields.
  Example values:
• IP: 192.168.1.100
• Gateway: 192.168.1.1
• DNS: 8.8.8.8, 8.8.4.4

Step 4: Save and Apply

• Save the configuration and exit nmtui.
• Restart the connection:

  sudo nmcli connection down <connection_name> && sudo nmcli connection up <connection_name>

Verify the configuration:

ip a
ping google.com

Method 2: Configuring a Static IPv4 Address Using nmcmcli (Command Line Interface)

The nmcli tool allows for direct configuration of network settings.

Step 1: Identify the Connection Name

List all connections:

nmcli connection show

Note the connection name (e.g., Wired connection 1).

Step 2: Set Static IPv4 Configuration

Replace <connection_name>, <static_IP>, <gateway>, and <DNS> with your network details:

sudo nmcli connection modify <connection_name> ipv4.addresses <static_IP>/24
sudo nmcli connection modify <connection_name> ipv4.gateway <gateway>
sudo nmcli connection modify <connection_name> ipv4.dns "<DNS>"
sudo nmcli connection modify <connection_name> ipv4.method manual

Example:

sudo nmcli connection modify "Wired connection 1" ipv4.addresses 192.168.1.100/24
sudo nmcli connection modify "Wired connection 1" ipv4.gateway 192.168.1.1
sudo nmcli connection modify "Wired connection 1" ipv4.dns "8.8.8.8,8.8.4.4"
sudo nmcli connection modify "Wired connection 1" ipv4.method manual

Step 3: Apply the Changes

Bring the connection down and back up:

sudo nmcli connection down <connection_name>
sudo nmcli connection up <connection_name>

Step 4: Verify Configuration

Check the IP settings:

ip a

Test connectivity:

ping google.com
