Change name interface

Sorry for my English…

I want to change the interface name, what I don’t know sure the steps…

First I should know my interface name and mac from it,

ip a

Seconds, down my NetworkManager,

sudo ip link set dev enp31s0 down

rename the device name, I’ll change to hallo0.

My question, what is the difference between used,

1-

sudo gedit /etc/network/interfaces

and write on this file

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug  hallo0
iface hallo0 inet dhcp

2-

With udev

sudo /etc/udev/rules.d/10-network.rules

and write on this file,

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="aa:bb:cc:dd:ee:ff", KERNEL=="eth*", NAME="hallo0="

What from the Two possibilities should use?

Can please someone help with this question, Thanks!

My problem was when to tried this steps the interface name not to change.

I found the problem because of it not change…

I did Two mistakes;

1 - I forget to link the file,

sudo /etc/udev/rules.d/70-persistent-net.rules

I does it with

sudo  ln -s /dev/null /etc/udev/rules.d/70-net-setup-link.rules

2 - Since Ubuntu 16.04 and Linux Mint 17 on the file,

/etc/udev/rules.d/70-persistent-net.rules

where i write,

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="aa:bb:cc:dd:ee:ff", KERNEL=="eth*", NAME="hallo0="

I had to write without the word KERNEL=="eth"*, so, I should to write,

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="aa:bb:cc:dd:ee:ff", NAME="hallo0="

As here to say.

The rest of the steps from my question is gut.

@bbwd345 It is nice that you were able to fix your own problem. Knowing the correct syntax to use in a configuration file can be tricky at times. By posting the solution to the problem others can learn how to do the same.
