Bonjour,
après l'upgrade en version 22 de ma fedora je me retrouve dans l'impossibilité de me connecter en SSH sur certains de mes équipements.
Tous les serveurs linux/unix la connexion se fait.
Par contre dès qu'il s'agit de mes switchs (ce sont des alcatels omniswitch 6450 et 6850E) je rencontre le message ci dessous.
J'ai vidé le fichier des "hôtes connus", et lors de la "première connexion" il me demande si je veux enregistrer ou non la clef. J'accepte il la met bien dans le fichier.
Après désinstallation / Purge des fichiers de conf etc / réinstallation le problème persiste.
Si vous aviez de idées, merci d'avance.
