Bonjour,
Sur un rpi3B+, ou se trouve la configuration réseau car /etc/network/interfaces ne contient que :
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
/etc/network/interfaces.d est vide
Merci
Gérard
