How do we disable predictable network interface names in xubuntu 15.10 ? I want my old interfaces naming like eth0 ... ethx, some of my software assumes eth0 interface to be present and is hard coded all over the place.

Remember to fix the offending software. You can't avoid using predictable network device names forever. – Michael Hampton♦ Dec 7 '15 at 13:44

I will certainly try though! ;) – Nullldata Jun 14 '16 at 14:06

And why do they make offending upgrades, forcing a naming cheme, totally different from the one used for many years? I find no reason, except breaking millions of working network setup scripts. – Nuclear Dec 6 '16 at 20:21

As root, in the file /etc/default/grub

Add net.ifnames=0 biosdevname=0 to the kernel command line in your grub config.

To do so, change the following line

GRUB_CMDLINE_LINUX=""

to

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

then save the file, run update-grub and then reboot.

is that it ? no need to modify dev-rules and other stuff ? – Ravikumar Tulugu Dec 7 '15 at 7:31
    
In Ubuntu 14.04 (mini.iso image) I do that but I only get the splash saying "Waiting for network configuration..." and network interfaces do not appear :( – aloplop85 Jul 18 '16 at 18:30
