How to find out a remote host's MAC/ethernet hardware address using arp/ping & how to protect against it

Asked by sunhux in Operating Systems Network Security, Network Security

Tags: , ,

Hi,

I've lost touch in this :

Is it possible from my PC (or a Unix station) to find out a remote host's
MAC/ethernet hardware address?

Thought we can clear our PC/Solaris's arp table (what's the command?
arp -d ?), then ping the remote server to fill up my PC/Unix station's
arp table & do "arp -a" to see the MAC addr?

I think I did not quite get this right, appreciate some pointers/correction.

I heard different manufacturers (Sun, HP, IBM, ...) are assigned a range
of MAC addresses their NIC (network interface card) can assume.
Is there a website somewhere that tells us this?

How can we protect against people from finding out our server's MAC
address?  How can we make the needed changes on our Cisco switch/
router, firewall or server to achieve this?Start Free Trial
