Hi All,
I have been Duck Duck Go'ing looking for how to discover
all the mac addresses on my Ethernet.
http://www.linuxinternetworks.com/how-to-find-out-all-mac-address-on-network/
Says to do: nmap -sP 192.168.1.0-255
Done that before and it does give you all the mac addresses
on 192.168.1.0/24, but it does not give you mac addresses
for those devices with different network configuration
on your Ethernet. (Like a stray access point on
192.168.88.0/24 on your Ethernet.)
I have tried these guys' java script:
http://www.ubnt.com/downloads/discovery/ubnt-discovery-v2.3.zip
It runs but doesn't find anything. Ran it in an XP VM too
and it struck out there either.
Does anyone know how to get all the mac addresses on your
Ethernet, even the ones configured on another network?
Many thanks,

MAC is layer2 so you cannot get the MAC from a different subnet, however you
can detect smb enabled system with the following command
$ sudo nmap -sU --script nbstat -p137 $subnet
$ nmap -sn --script address-info $local_subnet
or with http://www.inetcat.net/software/nbtscan.html
$ nbtscan $subnet
To get all MAC addresses use the network equipment
Example for cisco:
# sh mac address-table
# sh ip arp
For long time monitoring / reporting use netdisco, nedi or other tools.
Thank you
