Stretch and network names

The Raspbian Stretch network interface name is generated from your MAC address for that interface and it’s no longer easy to guess. While this was done to please the enterprise Linux users and their behemoth alike setups, it’s game breaking for many of us – Raspberry Pi users. Each time a piece of code would refer to the interface by eth0/wlan0 – it fails miserably on the new Raspbian Stretch.

Solution

The best solution to this is to disable the Raspbian Stretch network interface name changes at the boot level. You can do this by removing the SD card and adding this line to the cmdline.txt file:

net.ifnames=0

This will disable the new way of naming things and restore the old settings. You don’t have to reinstall the Stretch again. The changes will apply after the next reboot.
