Forum Linux.debian/ubuntu Probleme connection ssh

Bonjour,

Voilà j'ai un soucis avec des connections ssh sur des serveurs Lenny 5.0.
Quand je demarre la machine, je peux me connecter sur celle-ci.
Le problème intervient après le redémarrage des interfaces réseaux

/etc/init.d/networking restart

.
Après avoir effectuer cette commande, j'essaye de me connecter en ssh, je rentre le bon mot de passe, ça me connecte mais déconnecte aussi tot.

j'ai effectuer un debug avec ssh : ssh -vvv
Voila ce ke j'obtient après l'entree du mot de passe

Pour résoudre ce problème :
- j'ai essayer de redémarrer le démon ssh (rien ne change)
- j'ai mis le serveur ssh en débug (et la la connection se fait)
et apres ca si je redemarre le démon la connection ssh refonctionne jusqu'au redémarrage des interface via /etc/init.d/networking

Si vous pouviez m'aider, car là je ne comprend pas.

Voici le fichier de configuration du serveur ssh :
