<censure> de systemd !...
Bonjour à tous,
Considérons la partie réseau d'un serveur.
eth0 = LAN
eth1 = WAN1 (avec eth1:1->eth1:6) avec sept adresses IPv4 différentes
eth2 = WAN2 (avec une adresse IPv4 et un /64 Ipv6)
tap0 = openvpn TCP
tap1 = openvpn UDP
Cette configuration fonctionnait parfaitement avec init. Avec systemd,
ça merdoie (mais qui s'en étonnerait encore). Je subodore un problème de
dépendance entre les tap0/1 et le reste du réseau.
Les erreurs sont sur les modules :
- networking.service
- ifupdown-wait-online.service
Il n'y a pas de networkmanager, tout est fait à l'ancienne avec un
fichier interfaces en pièce jointe.

Je suppose que la seconde erreur est une conséquence de la première.
Donc je teste /sbin/ifup -a -n --read-environment... qui ne renvoie
aucune erreur ! De toute façon, ce fichier ne prend ni en compte tap0 ni
tap1.
La question est donc de savoir comment corriger la chose.
Bien cordialement,
