J'utilise Unison sur un ordinateur Windows 10 pour sauvegarder mes fichiers sur un serveur distant exécutant CentOS. Je me connecte à la machine distante sans mot de passe à l'aide d'OpenSSH et des clés publiques dans Cygwin. Je n'ai jamais eu de problèmes jusqu'à récemment.
Si je me connecte à la machine distante en utilisant ssh user@remoteaddressle shell Cygwin, je n’ai aucun problème et les touches fonctionnent. Si j'essaie exactement la même commande dans l'invite de commande Windows, la connexion demande mon mot de passe.
Tout cela a commencé après la modification de mon installation Cygwin. Cependant, j'ai essayé de réinstaller Cygwin et de générer de nouvelles clés, mais j'ai obtenu le même résultat.
Tous les threads que j'ai trouvés à ce sujet suggèrent de vérifier vos autorisations de fichier pour le répertoire .ssh sur le serveur et la machine locale. Toutefois, cela n’explique pas pourquoi cela fonctionne dans Cygwin mais pas dans Windows et que rien n’a changé sur le serveur.
J'ai ajouté Cygwin au chemin de l'environnement Windows correctement et je suis sshreconnu dans l'invite de commande. On a l'impression qu'OpenSSH ou Cygwin a été mis à jour et que la mise à jour a interrompu l'intégration avec Windows.
Je ne suis pas un programmeur, cela dépasse donc mes capacités pour le moment.
Voici les journaux de l'invite de commande et les journaux du shell Cygwin suivants:

SSH de MS Shell est même une version différente de celle de Cygwin:
Vous voyez la différence évidente entre Cygwin:
et MS:
La version MS recherche une paire de clés dans un chemin sans signification et ne la trouve pas. Vous aurez probablement besoin d'essayer depuis le shell Windows comme ceci:
