EDIT : Mettre exactement ce qui a été fait
J'ai besoin de SSH localhost sans mot de passe, la façon habituelle de le faire (avec des clés publiques) ne fonctionne pas.
user@PC:~$ rm -rf .ssh/*
user@PC:~$ ssh-keygen -t rsa > /dev/null
Enter file in which to save the key (/home/user/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
user@PC:~$ ls .ssh/
id_rsa id_rsa.pub
user@PC:~$ ssh-copy-id -i localhost
The authenticity of host 'localhost (::1)' can't be established.
RSA key fingerprint is f7:87:b5:4e:31:a1:72:11:8e:5f:d2:61:bd:b3:40:1a.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (RSA) to the list of known hosts.
user@localhost's password:
Now try logging into the machine, with "ssh 'localhost'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
user@PC:~$ ssh-agent $SHELL
user@PC:~$ ssh-add -L
The agent has no identities.
user@PC:~$ ssh-add
Identity added: /home/user/.ssh/id_rsa (/home/user/.ssh/id_rsa)
user@PC:~$ ssh-add -L
ssh-rsa ...MY KEY HERE
user@PC:~$ ssh-copy-id -i localhost
user@localhost's password:
Now try logging into the machine, with "ssh 'localhost'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
user@PC:~$ ssh localhost echo 'testing'
user@localhost's password:
user@PC:~$
Donc, comme vous pouvez le voir dans la dernière commande, il demande toujours le mot de passe ! Comment puis-je corriger cela ? Ubuntu-10.04, OpenSSH_5.3p1
EDIT2 :
Ajout de quelques informations sur le sshd
user@PC:~$ cat /etc/ssh/sshd_config | grep Authentication
# Authentication:
RSAAuthentication yes
PubkeyAuthentication yes
RhostsRSAAuthentication no
HostbasedAuthentication no
# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
ChallengeResponseAuthentication no
# PasswordAuthentication yes
EDIT3 : Ajout du résultat de $ssh -vv localhost
$ssh -vv localhost
...
