MAC address is shown on port scan
When I perform a portscan on my FreeBSD box using nmap on my linux box it comes back with the ports that are open along with the MAC address of the NIC.
When I portscan my linux box it doesn't return the MAC address. Is there something I need to configure on my BSD machine so that it does not report this? Or is this even necessary? Thanks. |
On the local network this is really not needed. You can get the MAC address for any box by just using the arp command. All you have to do is communicate with the machine in some way (nmap would work) and then use the arp command.

what I was wondering if it was not necessary to prevent this information from showing up when someone does a port scan from the internet. This is used as a web server.

Further, when the computers are not on the same Ethernet as the scanning computer... this information is unavailable -- which is why nmap can't return it. |
