Bonjour à tous,  
Je viens vers vous pour vous exposer mon probleme et obtenir de l'aide.
Je viens de débuter un stage en entreprise et je travaille avec mon ordinateur windows, et je doit me connecter a un serveur Unbuntu en ssh.
la connection s'établie bien chez mon collegue, mais j'ai l'impression que ma configuration .ssh n'est pas bonne, voici les messages d'erreurs:

:hello:

 

D'après tes logs, je dirais que tu aurais un soucis au niveau de ta clé publique. Le client ssh n'arrive pas à la trouver.

Bonjour,  
 
Je ne suis pas expert SSH mais a priori, voilà comment ça fonctionne :  

  • il faut générer une paire de clef,  sur le poste client, avec la commande

    ssh-keygen

  • copier la clef publique sur le poste server à la fin du fichier

    ~/.ssh/authorized_keys

     


La clef publique finit par pub
La clef privée ne doit jamais quitter le poste où elle a été générée
