Two hosts in internal network with VirtualBox

Hello, in this post I will show how to create and setting two hosts in internal network using Oracle VirtualBox.

Steps

1. Create two Linux VMs

2. Set adapter 1 as 'Internal Network' in both VMs

3. Start the VM1 and change the file /etc/network/interfaces to:

auto lo eth0
iface lo inet loopback

iface eth0 inet static
  address 20.10.0.100
  netmask 255.255.255.0

4. Restart the interface eth0

$ sudo ifdown eth0
$ sudo ifup eth0

5. Start the VM2 and change the file /etc/network/interfaces to:

auto lo eth0
iface lo inet loopback

iface eth0 inet static
  address 20.10.0.101
  netmask 255.255.255.0

6. Restart the interface eth0

$ sudo ifdown eth0
$ sudo ifup eth0

7. Check if both VMs are visible

In VM1, run the command

  $ ping 20.10.0.101

In VM2, run the command

  $ ping 20.10.0.100

8. Access VM2 from VM1 by SSH

$ ssh <username-in-vm2>@20.10.0.101

See you in the next post.
