Bonding (agrégation de liens) avec Netplan

Oui, je confirme, j’ai du configurer IPv6 dans netplan à la main sur mon vps Ubuntu 20.04 souscrit en mai 2020 (et qui a cramé à SBG2), ainsi que sur son remplaçant souscrit récemment à Gravelines.

Je ne comprends pas ce qui les empêche de le faire automatiquement avec cloudinit... Dans mon cas je maîtrise à peu près netplan donc pas trop de difficultés, mais en pratique j’imagine que plein de leurs clients VPS ne proposent pas leurs services en IPv6 uniquement par simple manque d’un fichier de configuration...

sudo netplan apply est la commande pour appliquer les changements.

sudo netplan try –config-file CONFIG_FILE est une alternative qui permet d'appliquer la configuration d'un fichier spécifique et de faire un retour arrière si vous avez perdu la main : netplan va attendre 120 secondes que vous confirmiez que c'est ok et en absence de confirmation fera un retour arrière.

Do you want to keep these settings?


Press ENTER before the timeout to accept the new configuration


Changes will revert in 113 seconds
Configuration accepted.

En cas de problème, la commande sudo netplan --debug generate permet dans certains cas de comprendre le problème.

journalctl --no-pager -lu systemd-networkd permet d'afficher des logs.

networkctl permet d'afficher les états des différentes interfaces:

# networkctl
IDX LINK   TYPE     OPERATIONAL SETUP     
  1 lo     loopback carrier     unmanaged 
  2 eno1   ether    routable    configured
  3 eno2   ether    no-carrier  configuring
  4 enp1s0 ether    routable    configured

Pour ne pas ralentir le démarrage de 120 secondes, une interface non utilisée, eno2 juste au-desus, ne doit pas être configuré dans Netplan.
Mettre dhcp4 et dhcp6 à "no" + accept-ra: false est insufisant : Netplan va attendre 120 secondes au démarrage.

Ce qu'il ne faut pas faire pour une interface Ethernet inutilisée :

    eno2:
      dhcp4: no
      dhcp6: no
      accept-ra: false

La solution ? il suffit de supprimer toutes les lignes faisant référence à cette interface.

Le fichier /etc/netplan/50-cloud-init.yaml proposé par OVH sur ses serveurs.... c'est une horreur !

A noter que j'ai caché une partie du préfixe IPv6 avec de xxxx : (2001:41d0:xxxx:b2b8::/56)

C'est un serveur OVH livré avec Ubuntu 20.04 LTS.
