Change default network name (ens33) to old “eth0” on Ubuntu 18.04 / Ubuntu 16.04
Change default network name (ens33) to old “eth0” on Ubuntu 18.04 / Ubuntu 16.04
Just after the Ubuntu installation, I came to know that the network interface name got changed to ens33 from old school eth0.

If you ever interested in changing interface names to old type ethX, here is the tutorial for you.
As you can see in the following command, my system is having a network adapter called ens33.
This is just the case of VMware environment, it may vary depends on the hardware but the steps to get back ethX will be the same.
$ ip a 1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: </loopback,up,lower_up>ens33: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:0c:29:05:a3:e2 brd ff:ff:ff:ff:ff:ff
</broadcast,multicast,up,lower_up>inet 192.168.12.12/24 brd 192.168.12.255 scope global dynamic ens33
valid_lft 1683sec preferred_lft 1683sec
inet6 fe80::20c:29ff:fe05:a3e2/64 scope link
valid_lft forever preferred_lft forever
From the dmesg command, you can see that the device got renamed during the system boot.
$ dmesg | grep -i eth [ 3.050064] e1000 0000:02:01.0 eth0: (PCI:66MHz:32-bit) 00:0c:29:05:a3:e2
[ 3.050074] e1000 0000:02:01.0 eth0: Intel(R) PRO/1000 Network Connection
[ 3.057410] e1000 0000:02:01.0 ens33: renamed from eth0
To get an ethX back, edit the grub file.
$ sudo nano /etc/default/grub
Look for “GRUB_CMDLINE_LINUX” and add the following”net.ifnames=0 biosdevname=0“.
From:
GRUB_CMDLINE_LINUX=""
To:
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
Generate a new grub file using the following command.
$ sudo grub-mkconfig -o /boot/grub/grub.cfg Generating grub configuration file ...

Edit the interface file and change the network device name so that you will have a DHCP or static IP address for ethX.

Assign IP Address
For Ubuntu 18.04
You can assign an IP address to the system using netplan – a new network configuration tool.
READ: How To Configure Static IP Address in Ubuntu 18.04 using Netplan
For Ubuntu 16.04 / Older
DHCP:
If your infrastructure has a DHCP server and you want to leverage that, then:
$ sudo nano /etc/network/interfaces
Update below lines in /etc/network/interfaces files so that the network card can get an IP address from DHCP server.
FROM:
auto ens33
iface ens33 inet dhcp
TO:
auto eth0
iface eth0 inet dhcp
Static:
If your infrastructure does not have a DHCP server, then you will need to configure a static IP address for all network interfaces on your Ubuntu machine.
$ sudo nano /etc/network/interfaces
From:
auto ens33
iface ens33 inet static
address 192.168.12.12
netmask 255.255.255.0
dns-nameservers 192.168.12.2
gateway 192.168.12.2
To:
auto eth0
iface eth0 inet static
address 192.168.12.12
netmask 255.255.255.0
dns-nameservers 192.168.12.2
gateway 192.168.12.2
Reboot your system.
$ sudo reboot
After the system reboot, just check whether you have an ethX back.
$ ip a
1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: </loopback,up,lower_up>eth0: <broadcast,multicast,up,lower_up> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:0c:29:05:a3:e2 brd ff:ff:ff:ff:ff:ff
</broadcast,multicast,up,lower_up>inet 192.168.12.12/24 brd 192.168.12.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fe05:a3e2/64 scope link
valid_lft forever preferred_lft forever
That’s All.
