Bonjour,
Je souhaite accéder au NAS de mon réseau local par ssh sans mot de passe.
1. Je commence par créer une paire de clés RSA
tt@ttx ~ $ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/tt/.ssh/id_rsa):
/home/tt/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/tt/.ssh/id_rsa.
Your public key has been saved in /home/tt/.ssh/id_rsa.pub.
Et je vérifie que j'ai bien créé une clé publique
tt@ttx ~ $ cat /home/tt/.ssh/id_rsa.pub

2. Je copie ma clé publique sur le NAS
tt@ttx ~ $ scp ~/.ssh/id_rsa.pub admin@192.168.1.15:
admin@192.168.1.15's password:
id_rsa.pub 100% 388 165.7KB/s 00:00
3. Je me connecte au NAS
tt@ttx ~ $ ssh admin@192.168.1.15
admin@192.168.1.15's password:
Le problème est que je suis obligé de saisir mon mot de passe, ce que je cherche précisément à éviter. Pourtant, la clé publique créée sur mon PC a bien été prise en compte par le NAS
