1. Adapter Configuration in VirtualBox Ubuntu Server 20.04

The previous discussion has discussed Installing Ubuntu Server 20.04 using VirtualBox. On this occasion we will discuss the IP Address Configuration on Ubuntu Server 20.04.

Create 2 adapters on the virtual machine:

  • Adapter Bridge (connect to wifi or lan connected to the internet)
  • Host Only Adapter (To connect to Host and Guest)
  1. Stage 1 : Click on the ubuntu server 20.04 virtual machine, then click network on the virtualbox.

    Configure Network VirtualBox
     
  2. Stage 2 : In Adapter 1 we will create a bridge adapter that is used for internet sources on the Ubuntu Server. Here I use a LAN cable. Alternatively you can use WIFI or Wireless.

    Brige Adapter : LAN

  3. Stage 3 : In Adapter 1 we will create a Host Only Adapter which is used for communication sources between guest and host or server and client.

Adapter 2 : Host Only Adapter

2. Run Ubuntu Server 20.04 Virtual Machine

After setting up the network adapter, next run the virtual machine, as shown below:

Finish Create Virtual Machine Ubuntu

3. How to Configure IP Address Ubuntu Server 20.04

  • Please login using root / super user.
  • Then configure the IP address using the command:

  • IP Address bridge: DHCP CLIENT
  • IP Address Host Only: 192.168.111.1/24
nano /etc/network/interfaces

Then equate the configuration as shown below:

Configuration IP Address

Description:

  • On enp0s3 using DHCP Client
  • On enp0s8 using Static IP Address 
# configuration ip address internet eth1 (bridge)
# dhcp
auto enp0s3
iface enp0s3 inet dhcp


# configuration eth2 atau enp0s8 (host only adapter)
# static
auto enp0s8
iface enp0s8 inet static
        address 192.168.111.1
        netmask 255.255.255.0
        network 192.168.111.0
        broadcast 192.168.111.254

Next, please save by CTRL+X then Y and ENTER.

To restart the ip address configuration results can use the command : 

systemctl restart networking

or if you want to use other commands, you can install tools with the command : (make sure you are connected to the internet)

apt install ifupdown net-tools

If you have finished and successfully installed the tools, then friends can restart the network with another command, namely :

/etc/init.d/networking restart

Restart Network

Then check the configuration results using the : ifconfig

Check Configuration IP Address

4. Windows IP Address Configuration Process

If you have finished configuring the IP Address on the Ubuntu Server, the next step is to configure the IP Address in Windows on the Host Only Adapter. Friends can follow the following steps:

open the network and sharing center, or simply: Windows + R, then type ncpa.cpl dan enter.

Configuration IP address Host Only

Result Configuration IP address Host Only

Please do testing on the Host and Server do the ping process between devices as shown below:

ping from windows to server
ping from windows to server

5. How to Install and Configure Ubuntu SSH Server

  • For the ssh server installation process on Linux Ubuntu 20.04, you can use the command:
apt-get install openssh-server
  • Make sure your server is connected to the internet.

Install SSH Server

  • If you notice, when we run the openssh-server command, some packages follow the install as well, openssh-client and openssh-sftp-server.
  • Next, if you have finished installing openssh-server, friends can see the status of the ssh server using the command:
/etc/init.d/ssh client

cek status ssh server

  • Testing SSH Server on Host / Windows.
  • If so, we will do SSH Connection, using the PuTTY application, friends can download it on the official website, https://www.putty.org/
  • Enter the Server's IP Address

Remote SSH with IP

  • If so, then click Accept on Putty

Accept Putty

  • Here we will log in using the user we created at the beginning of the install.

remote ssh login user with putty

  • And here we have successfully logged in, and friends can also log in using the super user with the command:
  • sudo su

Login Super User
