Comment faire fonctionner une connexion ethernet pour un ordinateur sous Debian ?
Il peut y avoir plusieurs soucis :
- paramétrage incomplet (inexistant) pour ce type de connexion
- absence de pilote pour gérer la carte réseau derrière la prise RJ45
Cas pratique
Comme pour la plupart des soucis matériels, un coup d'oeil à /var/log est utile.
