Résumé :
Je ne peux pas me connecter à un VPN avec Cisco IPSec, apparemment parce que le secret partagé n'est pas enregistré après avoir été saisi (il reste toujours vide).
Explication détaillée :
J'ai créé une connexion VPN avec Cisco IPSec et je me suis connecté avec succès. Soudain (quelques heures plus tard), j'ai été déconnecté et j'ai obtenu l'erreur suivante après avoir essayé de me reconnecter :
"Le serveur VPN n'a pas répondu. Vérifiez l'adresse du serveur et essayez de vous reconnecter."
L'adresse était correcte, donc j'ai vérifié les journaux et j'ai trouvé :
Feb 22 17:59:35 gerry racoon[4401]: couldn't find the pskey by address 204.232.144.166.
J'ai vérifié le secret partagé et il était vide ; je l'ai tapé à nouveau, j'ai cliqué sur ok et je l'ai ouvert immédiatement et j'ai obtenu à nouveau un secret partagé vide. J'ai à nouveau tapé le secret partagé et j'ai essayé de me connecter et j'ai obtenu les logs suivants :

J'ai cherché des informations concernant ces journaux mais je n'ai pas pu déterminer s'ils étaient liés au problème.
J'ai essayé de supprimer la connexion VPN et d'en créer une nouvelle (d'ailleurs, je n'ai pas pu utiliser le même nom) et cela n'a pas fonctionné non plus donc, à nouveau, j'examine les journaux :
Feb 22 18:16:26 gerry nesessionmanager[951]: Failed to load configuration with ID <__NSConcreteUUID 0x7fedfa504910> A7892601-20D6-4D80-88B7-8D2AA22CF4E1

Malheureusement, je n'ai pas pu faire quoi que ce soit sans ces journaux (le même journal s'est répété environ 20 fois et s'est arrêté), alors j'ai supprimé toutes mes connexions VPN (à nouveau), j'en ai créé une nouvelle (cette fois, j'ai pu choisir le même nom) et j'ai obtenu une entrée de journal différente :
Feb 22 18:31:49 gerry nehelper[217]: 3C44D371-6954-4001-A2D7-0100446EDA8A.XAUTH: SecKeychainItemCreateFromContent failed: User interaction is not allowed.
Feb 22 18:31:49 gerry nehelper[217]: 3C44D371-6954-4001-A2D7-0100446EDA8A.SS: SecKeychainItemCreateFromContent failed: User interaction is not allowed.
Finalement j'ai cherché l'entrée du trousseau (dans keychain access) pour ma connexion VPN mais je n'en ai pas trouvé. Je suppose que cela pourrait être le problème.
Une idée de ce qui pourrait être le problème ? J'ai essayé de me connecter sur un autre Mac (même système d'exploitation, El Capitan) et je n'ai eu aucun problème, mais je n'arrive pas à faire fonctionner le VPN sur mon Mac.
Merci !
