Bonjour,
En consultant la documentation sur le paquet udhcpc, je tombe sur la
page suivante :
https://packages.debian.org/stretch/udhcpc
Sauf erreur de ma part, il y a une erreur sur la description du paquet,
car udhcpc est bien un client dhcp et non un serveur ; le c à la fin est
bien celui de client. Contrairement à ce qui est écrit sur cette page,
le serveur est toujours et encore udhcpd (le d pour daemon à la fin).
C'est trompeur car c'est bien busybox qui fournit les 2 fonctions, mais
le résultat des commandes est formel :
*$ busybox --help*

BusyBox is a multi-call binary that combines many common Unix
