Any help will be appreciated.
ip command instead of the outdated
$ ip addr show
link/ether field of the output is the MAC address (Both for Wi-fi and ethernet connections, MAC address is represented by
link/ether). Mostly this will be present in the second line.
$ ip addr show 1: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether a0:54:9f:53:b2:6e brd ff:ff:ff:ff:ff:ff
In my case
a0:54:9f:53:b2:6e is the MAC address.
Try ifconfig, and look at the "HWaddr".
okay, this is a very easy solution. 1/ Open a terminal 2/ ifconfig A list of network capable devices will be displayed. If you are using wireless, it usually is called wlan0, but can also be named pan0 wifi0 etc. A physical conection is most likely eth0. on the first line you will see your mac address. here is a sample of what you might see eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
You can spoof your mac address too with macchanger (sudo aptitude install macchanger) just type man macchanger to learn more
You can also right-click on the GNOME Network Manager. There you choose connection information and the following window shows you the hardware address. See also NetworkManager at Ubuntus Wiki.
