Problème authentification clés SSH - Jessie

Support Debian
#1

Yahallo,
J’ai un problème, le voici :
J’ai généré la clé publique ainsi que la privée, en 4096 bits RSA.

J’avais fait une authentification sur clé sur mon premier VPS. Sur mon second, depuis une réinstallation de l’OS, j’ai refait la même manipulation que pour mon premier VPS.

Mais rien ne fait, j’ai chmod -R 777;chown $USER:$USER sur le .ssh du client et du serveur, mais j’ai toujours “pubkey denied”

Pourriez-vous m’aider svp ?

Car sur mon premier VPS, tout fonctionne… Sur mon second, depuis la réinstallation, il me troll…

#2

Peut-être qu’un

ssh -v

permettrait d’en savoir plus sur l’erreur ?

Voici ce que ça donne.
Effectivement, mes clefs sont proxy et proxy.pub
Comment faire en sorte qu’il cherche “proxy” et non “id_rsa” ou autre… ?

(merci, j’avais oublié le mode verbose :x)

Tu peux utiliser l’option -i de ssh pour préciser la clé.

Aaah merci !
