How to Change Interface Card Name on Ubuntu

Hi,

This post is a short of the original one posted here.

Let’s say that you wanna change the interface name from enp4s0 to eth0. All you have to do, is to change the name enp4s0 to eth0 in the proper configuration files.

Edit the file /etc/udev/rules.d/70-persistent-net.rules and change the field NAME with the name that you want. (ex: NAME=enp4s0 is gonna be NAME=eth0)

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

Edit the file /etc/network/interfaces and change the interface name properly (ex: enp4s0 is gonna be eth0)

$ sudo vim /etc/network/interfaces

Now, reboot your system.

That’s all,

Moving from udev to eudev on Gentoo system

Hey, it’s been a while,

This simple post is gonna be about “How to move from udev to eudev?” For those of you who don’t know what udev is, basically speaking, it is a device manager that handle events from userspace apps that try to access devices on /dev. And, eudev is an improvement of udev.

I was using the deprecated version and I was kinda insecure in performing the upgrade on my Gentoo system :). Fortunately, I’ve found a “correct” way to do that. At least, I didn’t have problems. The steps are simple and direct. I’ll share here.

# emerge -Ca udev 
# emerge -1a eudev 
# etc-update 
# emerge @preserved-rebuild

After removing udev to install eudev, just make sure that your computer/notebook will not turn off for some reason, because if it happens, you’re gonna have a big trouble :).

The original post, was found on this thread here.

That’s all for today,
See ya
