I have a linux server that people on my lan have been trying to break into. The logs clearly show the ip (maybe spoofed) that the attacks are comming from the problem is that the IP is a dhcp address and I don't control the DHCP server. My question is: is there a way to also log the mac or hardware address of machines trying to login through SSH?
Mac addresses are readable between hardware that is directly connected. And any thing that is past the first piece of hardware is not easyaly readable if at all.
