What you are asking for is not possible with Ethernet networking.Whenyour IP packets have to cross a network boundary by way of a routerthereal destination MAC address is masked by the router.Not at the IP level, but the MAC is available through querying higher level protocols.
Yes. Fortunately though, nmap doesn't handle Cisco's (or any other vendors, for that matter) proprietary protocols. Since the question regarded nmap use, the answer is still valid (except that it masks the *source* MAC address. The destination MAC is determined by the switch, or not at all if a hub is used). -- Andreas Ericsson andreas.ericsson () op5 se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev
