Réseau

Sur le VPS OVH il faut désactiver l’initialisation réseau par le cloud

# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}

Création du fichier /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg en mode su

echo "network: {config: disabled}" > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

Modifier le fichier /etc/network/interfaces

auto ens3
