J'essaie d'utiliser cygwin sshd pour me connecter à une machine virtuelle Windows 8. Je l'ai installé et il semble fonctionner correctement. Localement - c’est-à-dire dans un terminal cygwin sur la machine Windows - si je ssh à localhost cela fonctionne correctement. À distance - depuis une autre machine - cela échoue.
Le problème semble être lié au nom d'utilisateur. L'utilisateur est 'ingres' et est un utilisateur local de la machine (MASPA05-VM01). Cependant, la machine fait partie d'un domaine et l'entrée / etc / password ressemble à ceci:
MASPA05-VM01+ingres:*:...
Quand je ssh localement, il me demande mon mot de passe et je le sais et ça marche. Si je le fais à distance en tant que 'ingres', c'est-à-dire que ssh ingres @ maspa05-vm01, il me demande un mot de passe mais le rejette. Si j'utilise le nom d'utilisateur complet selon / etc / passwd (ssh MASPA05-VM01 + ingres @ maspa05-vm01), il se déconnecte immédiatement.
Voici la sortie ssh -vvv:

J'ai essayé d'utiliser une clé publique mais cela pose le même problème. Quelqu'un peut-il suggérer une voie à suivre?
UPDATE: Voici la sortie du journal sshd (observateur d'événements)
The description for Event ID 0 from source sshd cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
sshd: PID 2400: fatal: seteuid 197611: Operation not permitted
Ce qui implique que le processus sshd manque d'autorisations. Cependant, il fonctionne en tant que compte SYSTEM.
Avez-vous consulté le journal sur le serveur sshd?
