UcremBlog #1: How to change Ethernet name on Ubuntu 16

Hi,

From Ubuntu 16 a change was introduced regarding the name of the network interfaces.
In fact, since release 16, Ubuntu calls the enpXsX network interfaces and no longer ethX.

It may also happen that with a hardware-level system change (such as adding a graphics card or any PCI card), when you restart the system, the network interface name changes.

To overcome this problem and then return to the ethX name and make it permanent I created this little guide.

Warning! Execute these commands only if you have access to the machine locally, you may lose your connection and no longer reach your machine.

ok let's start!

Point 1) Edit the Grub with the following command:

sudo nano /etc/default/grub

Add or change the following line:

GRUB_CMDLINE_LINUX = "net.ifnames = 0 biosdevname = 0"

Save the file and exit.

Step 2) Update the Grup with the following command:

sudo update-grub

Step 3) Restart

On reboot, if you do an ifconfig you do not see the network card do these other steps:

Step 1) Edit the interfaces file:

sudo / etc / network / interfaces

Change the enpXsX names to ethX
Save and exit

Step 2) Restart the network services:

sudo /etc/init.d/networking stop sudo /etc/init.d/networking start

now if you redo the ifconfig command you should find your network card with the name ethX and it will remain in such a way after every reboot, even if you change the hardware of the machine.

If you have any question or problem let me know and i answer asap :)

Bye
