I was going to say or.... Edit the file /etc/udev/rules. d/70-persistent-net and change the "stange names" back to their "proper name" but ..... It seems that even though the /etc/udev/rules.d/ directory still exists, it is empty, no 70-persistent-net file present. See https://wiki.debian.org/NetworkInterfaceNames why and how to get another set of predictable names like lan0 if you want that. Bonno Bloksma
