Bonjour,
J'utilise git et une connexion SSH pour push mes développements web sur un serveur de production, j'ai donc crée un repository sur mon serveur (Serveur windows 2012 R2) et installé git et OpenSSH sur le serveur.
Tout fonctionnait très bien jusqu’à ce q'une mise à jour windows et le redémarrage du serveur vienne poser problème.
Maintenant quand je tente une connexion ssh au serveur par le biais du prompt windows, mon mot de passe est demandé comme d'habitude puis immédiatement j'obtient "Permission denied, please try again".
Sachant que je suis absolument sûr de mon mot de passe ainsi que de l'adresse du serveur.
voici le fichier sshd_config du serveur : (c:/programData/ssh)

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

j'ai vraiment fait le tour de la plus part des forums et je commence à désespérer,
D'avance merci.

[transgohan]

Cela semble être des problèmes de droits sur le répertoire utilisateur, ou bien des fichiers du répertoire utilisateur qui ont été supprimés.
Vérifiez qu'il y a bien un dossier .ssh avec vos fichiers de clé dans votre répertoire utilisateur.

[mDaud]

Bonjour et merci pour votre réponse,
alors sur ma machine locale j'ai bien dans C:/Utilistaeurs/mdaudruy/ un dossier .ssh avec les droits "controle totale" pour moi et j'ai même ajouté "tout le monde" dans le doute.
Et même chose pour le dossier C:/Utilisateurs/mdaudruy/.ssh sur le serveur.

[transgohan]

Et vous avez bien un fichier config dans ce dossier ?

[mDaud]

ah non sur mon poste j'ai trois fichiers :
id_rsa
id_rsa.pub
known_hosts
et coté serveur :
known_hosts
id_rsa
id_rsa.pub
authorized_keys

j'ai un fichier sshd_config dans C:/programData/ssh par contre, celui que j'ai joint dans mon premier post.

[transgohan]

Va peut être falloir faire une réinstallation alors.
Car :

debug3: Failed to open file:C:/Users/mdaudruy/.ssh/config error:2

Il cherche bien un fichier nommé config.
