Le renvoi d'agent SSH ne fonctionne pas

Mon transfert d'agent SSH ne fonctionne pas. La réponse de cette question est assez ancienne et la réponse est en contradiction avec les commentaires. Pouvons-nous avoir une réponse mise à jour s'il vous plaît?

Fondamentalement, je peux SSH de l'ordinateur A à l'ordinateur B, ou de l'ordinateur A à l'ordinateur C, mais pas de l'ordinateur A à l'ordinateur B, puis de l'ordinateur B à l'ordinateur C. Lors de la connexion de l'ordinateur A à l'ordinateur B ou à l'ordinateur C, je l'ai toujours Utilisez ssh -A pour forcer le renvoi d'agent SSH. Mais je ne peux toujours pas connecter l'ordinateur A -> ordinateur B -> ordinateur C sans avoir été demandé une phrase secrète.

echo "$SSH_AUTH_SOCK" fonctionne à la fois sur le serveur et sur ma machine locale, mais sur SSH de A -> B, ssh-add -l rend:

L'agent n'a pas d'identité.

Alors qu'il énumère deux clés sur A.

Les trois machines sont configurées avec la configuration Ubuntu SSH standard sans aucune modification, le contenu de /etc/ssh/ssh_config et /etc/ssh/sshd_config est publié à http://paste.ubuntu.com/11482964/ .

EDIT: selon la demande,

Voici le journal de -Avvv de B à C:
