Ganti Network Management

Karena kita menggunakan ubuntu, maka kita akan mengubah Network Management bawaan ubuntu yaitu netplan menjadi ifupdown. Kita menggunakan Network Management ifupdown karena mudah diaplikasikan.

Install Ifupdown

Install ifupdown.

sudo apt-get install ifupdown

Tambah konfigurasi di /etc/network/interfaces seperti berikut:

/etc/network/interfaces

#Konfigurasi loopback
auto lo
iface lo inet loopback
 
#Konfigurasi DHCP
auto enp0s3
iface enp0s3 inet dhcp
 
#Konfigurasi Manual / Static
auto enp0s8
iface enp0s8 inet static
    address 192.168.56.2
    netmask 255.255.255.0

sudo ifdown --force enp0s3 enp0s8 lo && ifup -a

sudo systemctl unmask networking

sudo systemctl enable networking

sudo systemctl restart networking

Hapus Netplan

Sekarang kita akan menghapus Network Management lama yaitu netplan.

sudo systemctl stop systemd-networkd.socket systemd-networkd networkd-dispatcher systemd-networkd-wait-online

sudo systemctl disable systemd-networkd.socket systemd-networkd networkd-dispatcher systemd-networkd-wait-online

sudo systemctl mask systemd-networkd.socket systemd-networkd networkd-dispatcher systemd-networkd-wait-online

sudo apt-get --assume-yes purge nplan netplan.io
