Change default network name (ens33) to old “eth0” on Ubuntu 16.04
Just after installing Ubuntu 16.04, I came to know that the interface network name was changed to ens33 instead ethX. Would you back the good old ethX follow just these small steps.
Open a terminal and Edit the grub file: sudo nano /etc/default/grub
Once opened the grub file is look forward to GRUB_CMDLINE_LINUX=”” between the double quotes place the following: net.ifnames=0 biosdevname=0
Ready, Save as ctrl x and then create a new grub file: sudo grub-mkconfig -o /boot/grub/grub.cfg
Quick reboot and ready.
