5. Setting network adapter Ubuntu Client di VB

6. Jalankan Ubuntu server dan Ubuntu client pada VB- Pastikan Windows sudah terkoneksi internet- Matikan firewall pada linux

# sudo ufw disable- Ubuntu server sudah terinstall paket yang dibutuhkan

# sudo apt-get update# sudo apt-get install telnetd# sudo apt-get install openssh-server# sudo apt-get install vsftpd# sudo apt-get install nfs-kernel-server# sudo apt-get install portmap nis# sudo apt-get install samba

- Ubuntu Client sudah terinstall paket yang dibutuhkan# sudo apt-get update# sudo apt-get install nfs-client# sudo apt-get install nis portmap nis

B. Configurasi Ubuntu Server1. Setting IP Ethernet 0 dan 1

- Buka terminal (Ctrl+Alt+T)- Masuk sebagai root
