How can I get MAC address in ubuntu 16.04?

16.04 command-line networking wireless ethernet

You can find the MAC address for your network devices with the terminal command:

sudo lshw -C network

The MAC address is called 'serial,' like this, for example:

*-network                 
       description: Ethernet interface
       product: Ethernet Connection I217-LM
       vendor: Intel Corporation
       physical id: 19
       bus info: pci@0000:00:19.0
       logical name: enp0s25
       version: 04
       serial: 11:22:33:44:aa:bb
       capacity: 1Gbit/s
       width: 32 bits
       clock: 33MHz
       <snip>

If your devices do not appear in ifconfig then they are probably not yet claimed by any drivers.

I tried with several commands, but it does not work, please see the command:

How can I get MAC?

If ifconfig -a does not return any Ethernet device, the device is not connected or the driver is missing. Take a look into dmesg and search for issues with your network hardware

where did you get enp3s0 from?
