DHCP connection cablé non fonctionnel


Bonjour,

Je suis actuellement sur des macmini qui on était réinstaller en Linux 16.04 LTS 64bit,

Je souhaite les connecter (il y en a 3) sur internet mais je rencontre une difficulté.
L'un fonctionne correctement :

Mais quand j'utilise le même cable réseau cela ne fonctionne pas sur les autres.
Peut être dois-je configurer des actions sur le NAS ou le D-Link

L'on me parle aussi de peut-être devoir modifier le fichier /etc/init.d

Je ne suis pas trop un spécialiste ! mais j'aimerais bien faire fonctionner mes machines sur le réseau.

I try to change the wire no change ! I connect the wire who works to the other macmini same problem


Peraps is configuration on NAS or D-Link (rout ?)

I had read peraps the problem come from /etc/init.d

I'm aware to code but not really professional of networking. Had you some advice ?
