I'd like to create a VirtualBox machine that monitors three networks:

Network 1 (name: client):

• Type: Ethernet. Has DHCP and DNS Servers. Contains the hosts A (
  10.1.1.10 ) and B ( 10.1.1.20 ). It's connected to an ISP.

Network 2 (name: server):

• Type: Ethernet. Doesn't have DHCP or DNS Servers. Contains the hosts
  C ( 10.1.2.10 ) and B ( 10.1.2.20 ). It's isolated.

Network 3 (name: management):

• Type: Wifi. Has DHCP and DNS Servers. It's isolated.

I have to be able to access every network and machines using it's name.

I have created 3 network adapters for my VM, the first one Bridge, the two others Internal Network (I am not sure if it's correct).

I did rename the three interfaces to 'network1', 'network2', 'network3' respectively.

I have configured my /etc/network/interfaces as follow:

allow-hotplug network1

iface network1 inet dhcp



allow-hotplug network2

iface network2 inet static

   address 10.1.2.3   #not sure, I just gave one random adress for this machine

   network 10.1.2.0

   netmask 255.255.255.0

   gateway 10.1.2.1

   broadcast 10.1.2.255



allow-hotplug network3

iface network3 inet dhcp

I also added all the A, B, C, D machines in my /etc/hosts (I don't know if that is what I am supposed to do).

Lines I added in /etc/hosts:

10.1.1.10    A

10.1.1.20    B

10.1.2.10    C

10.1.2.20    D

My questions are the following:

1. Are the type of my network adapters set up correctly? (Bridge, and
   internal network for the isolated)


2. How do I make my third network adapter to be wireless mode?


3. My network2 doesn't have a DNS Server. What does it really mean?


4. Was I meant to edit the /etc/hosts to monitor those connected
   machines?


5. Do I have to edit the /etc/networks to give symbolic names to these too?


6. Am I missing something basic that would help me to understand this setting?

Thanks.
