Bonjour,
J'ai un soucis de config avec ssh qui je pense est un grand classique : pouvoir se connecter en ssh sans avoir la demande de mot de passe.
J'ai 2 machines, la "dagda" est le client et "andarta" le serveur.
Sur andarta j'ai sshd donc voici la config (jai mis les lignes non commentées seulement) :
AuthorizedKeysFile .ssh/authorized_keys .ssh/authorized_keys2
KbdInteractiveAuthentication no
UsePAM yes
X11Forwarding yes
PrintMotd no
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
Sur dagda j'ai créé ma clé comme ceci avec un password :
Je l'ai ensuite envoyée sur andarta :
ssh-copy-id -i ~/.ssh/id_ed25519_andarta.pub stephane@192.168.1.101
Si je test une connexion, le password est toujours demandé.
Droits des fichiers sur dagda :
-> dossier .ssh :
drwx------ - stephane 22 févr. 11:58 .ssh
-> clés :
.rw------- 464 stephane 22 févr. 11:52 id_ed25519_andarta
.rw-r--r-- 96 stephane 22 févr. 11:54 id_ed25519_andarta.pub
Droits des fichiers sur andarta :
-> dossier .ssh :
drwx------ 2 stephane stephane 4096 22 févr. 11:53 .ssh
-rw------- 1 stephane stephane 96 22 févr. 11:53 authorized_keys
Le contenu de authorized_keys est identique a ce qui se trouve dans id_ed25519_andarta.pub
Sur dagda j'ai rajouté ceci dans .ssh/config :
Host "Andarta"
HostName 192.168.1.101
User stephane
IdentityFile /home/stephane/.ssh/id_ed25519_andarta
Si je tente une connexion comme ceci le password est aussi demandé :
ssh stephane@192.168.1.101 -i ~/.ssh/id_ed25519_andarta
Logs :
ssh stephane@192.168.1.101 -v
