Bonsoir!

Ça faisait longtemps que je ne passais pas par là, et ce soir j'ai une petite question 
(j'espère qu'il y aura quelqu'un là, même le week-end). J'essaie depuis ce matin de 
configurer ssh pour avoir un accès direct à toutes les 2 machines de mon réseau local par 
n'importe quel utilisateur. J'ai trouvé plusieurs tutos sur le net, j'ai lu plusieurs 
rapports de bug non conclusifs, et je ne m'en sors pas. 

Machine 1: 
coruja.comuna.andre -> 192.168.254.10

Machine 2:
sofocles.comuna.andre -> 192.168.254.1


Voilà ce que j'ai déjà fait (les fichiers de config sont de la machine 1):

1) J'ai créé /etc/shosts.equiv . D'abord avec seulement le nom de la machine, puis avec 
trois lignes,:
sofocles
sofocles.comuna.andre
192.168.254.1

2) Dans /etc/ssh/sshd_config j'ai mis:
HostbasedAuthentication yes

3) Dans /etc/ssh/ssh_config:
    HostbasedAuthentication yes
    EnableSSHKeysign yes

4) J'ai crée /etc/ssh/ssh_known_hosts avec la commande
ssh-keyscan -t rsa coruja > /etc/ssh/ssh_known_hosts

Puis je l'ai édité et j'ai mis sofocles,sofocles.comuna.andre,192.168.254.1 à la première 
colonne.

J'ai vérifié, re-vérifié 20 fois, et ça ne marche pas. J'ai trouvé quelques rapports de bug 
assez anciens qui parlaient de problèmes semblables, mais avec de petites différences. 
Alors aidez-moi, aidez-moi :)

Voilà ce que me donne `ssh -vvv coruja`:
