mac address on result #76

Open ekuzu opened 3 years ago

ekuzu commented 3 years ago

Do you plan to add mac address of founded machines on results?

eviltik commented 3 years ago

Hi

Well. Not sure i can go under the TCP layer using nodejs without a third party module. Or perhaps i got the mac in node network layer, probably.

PR welcome ? :)

Hi there, just thinking ... what is your use case ?

michaelniemand commented 2 years ago

We have this requirement as well. We need to distinguish if the physical machine changed. Would be a great addition!

eviltik commented 2 years ago

I perfectly understand the need. It make sense only on the same LAN segments. It not on the same LAN, if you try to get remote clients' MAC addresses, you'll end up with the address of a router more than likely.

Are we all agree about that ?

michaelniemand commented 2 years ago

oooooh damn, you're right. ICMP doesn't even contain the MAC. Phew, in that case it wouldn't make much sense at all, because it's not reliable

eviltik commented 2 years ago

Yep, but it can be usefull on the same LAN segment. @ekuzu what is your use case ? ty

Sorry for late response, We had same use case like @michaelniemand , MAC is the unique identifier for machine in private networks. And of course it's just useful for local network

Example; I want to detect all open 9100 ports in our network (Printers) and save them to a database (IP, MAC, CustomName) with their MAC, if a printer has change on his IP then i can detect it easily over MAC identifier in our database and set new IP for it.
