Mac Address not well reported when scanning network

[thongor77]

Hello,

not sure if it's a bug or something not fully implemented but when I scan my Network most of the time it report 00:00:00:00:00:00 as MAC Address (mostly when scanning an address where a Macintosh is connected to but not only)

thanks

Hi @thongor77,

where do you see the 00:00:00... as output? In the view (arp or netbios?) / copy&paste / export?

There are currently two ways to detect the MAC address of a host.

1. ARP - which will only work on the same layer 2 network. You can verify this with

   # run ping agains host
   ping <IP_ADDR>
   # get local arp table
   arp -a
   

   You should find here the MAC address of the host there...

2. NETBIOS which is not supported by every operating system...
