Add Static Ip Address Via Cli
sudo vim /etc/network/interfaces
Example:
# The primary network interface
allow-hotplug eno1
iface eno1 inet static
address 10.189.1.234
netmask 255.255.255.0
gateway 10.189.1.1
dns-nameserver 10.189.1.49
Then restart the networking systemd service for the changes to be implemented:
sudo /etc/init.d/networking restart
