On the Debian machine. Such machines in the subnet can be multiple, they differ only in a MAC. The network interface may not be configured or is configured incorrectly.
Need a way (preferably under Windows) to do the following:
1) "scan" a subnet to determine which Maki correspond to these machines.
2) on the selected machine with the specified MAC to set IP, subnet and gateway (DHCP will not do, the engineer should come one time with a laptop, configure all the machines and leave. After that the car will operate autonomously even after a reboot).
Ie actually need to be able remote configuration interface using only Data Link Layer.
It is assumed (without it not even do) that the cars constantly worked any services listening to the network.
