Aucun problème de port ou de routeur malheureusement, d'ailleurs on voit bien dans le log ssh que l'authentification fonctionne. Je suis à peu près certain que c'est un problème intra-NAS

Oui, il y a eu plusieurs redémarrages depuis, et j'ai essayé avec SSH, telnet, en désactivant puis réactivant...

Bonjour à tous, Depuis quelques jours (je soupçonne la dernière mise à jour non-bêta), je n'arrive plus à me connecter en SSH via Putty. Voici le message d'erreur que j'ai : OpenSSH_7.6p1, OpenSSL 1.0.2m 2 Nov 2017 debug2: resolving "myserver.synology.me" port 220 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to
