How to discover the mac address of machines in a network?
I need to discover the machines that are available just with only BIOS
installed (NO Operating System)
And I need to find the mac address of such machines that are up.
Unless a machine starts transmitting any data on the network,
you can't find any information about it.
If your BIOS attempts PXE boot, you can capture the MAC ID
from the DHCP broadcast request. ?Or if you have a managed
L2 switch, you can query its ARP table for list of all MAC IDs
it has learned.
Wake on Lan would be surely there. PXE boot needs manual/ requies agent(OS)
which is not possible.
From what I recall, the wake on lan utility "wol" requires MAC address.
