connect

To communicate over a network, a computer must have an IP address.

The computer can choose its own IP address (static) or can ask a DHCP server to assign one (dynamic).

Generally, clients (smartphones, laptops, etc...) rely on DHCP servers to have a dynamic IP address and servers have a static IP address.

For this project you will need to add these 3 VM :

For VirtualBox

For UTM

The VM are configured like this :

        N E T W O R K S                C O M P U T E R S

You will only have control over "machine2". This computer have Internet access through the "box".

Machine Credentials: Use 'root' as the login and a single space (' ') as the password.

Configure the network of the connect_box to use the NAT network, following the diagram provided above.

Start the 3 VM and test on machine2 the connectivity quality with this command :

timeout --signal SIGINT 1m ping google.com

After one minute the result shows the percentage of lost packets. It should be quite high (above 10%). machine1 and machine2 have the same IP address, which leads to connectivity problems.

Find how to :

  • change the IP address to avoid the conflict
  • make the IP address dynamic (attributed by the box DHCP server)
