Changing the name of the interface on eth0 enp3s0 in debian 9

The system debian 9 The default interface is not eth0 and enp3s0.

Interface Name is set during boot:

r8169 0000:03:00.0 enp3s0: renamed from eth0
r8169 0000:03:00.0 enp3s0: link down
r8169 0000:03:00.0 enp3s0: link down
IPv6: ADDRCONF(NETDEV_UP): enp3s0: link is not ready
r8169 0000:03:00.0 enp3s0: link up
IPv6: ADDRCONF(NETDEV_CHANGE): enp3s0: link becomes ready

We can very easily restore the old naming interface - just edit the file:

nano /etc/default/grub

And change:

GRUB_CMDLINE_LINUX=""

na:

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

Then we generate a new configuration file thick:

grub-mkconfig -o /boot/grub/grub.cfg

and modify the configurations of network interface:

nano /etc/network/interfaces

changing the name from there on eth0 enp3s0.
