To change NIC names after fresh setup of Debian 9 you must add/send: ~# touch /etc/udev/rules.d/10-network.rules && chown root:root /etc/udev/rules.d/10-network.rules ~# YOURMAC="00:12:34:AB:CD:EF" ~# YOURNICNAME="eth0" ~# echo -e "SUBSYSTEM==\"net\", ACTION==\"add\", DRIVERS==\"?*\", ATTR{address}==\"$YOURMAC\", ATTR{dev_id}==\"0x0\", ATTR{type}==\"1\", KERNEL==\"eth*\", NAME=\"$YOURNICNAME\"" >> /etc/udev/rules.d/10-network.rules ~# echo -e 'GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"' >> /etc/default/grub ~# update-grub && reboot Have fun!
