[résolu] ssh : permission denied après installation de webmin

Bonsoir,

lorsque j'ai installé Ubuntu server 10.04, j'ai suivi le tuto qui expliquait comment installer et activer ssh. Et jusqu'à il y a peu, ça fonctionnait. J'ai ensuite installé Webmin pour configurer mon serveur en clicodrome et je ne me suis plus trop occupé de ssh.
Depuis quelques jours, j'essaye à nouveau de me connecter avec ssh mais je récolte un "permission denied" lorsque j'indique le mot de passe. Il est vrai que j'ai fait quelques tests avec Webmin. Aurais-je touché quelque chose que je n'aurai pas du ? Pourtant, dans les réglages ssh, j'ai bien indiqué mon login comme autorisé à se connecter en ssh. Que puis-je faire ?

D'avance merci.

Re : [résolu] ssh : permission denied après installation de webmin

peux-tu donner le retour de :

ssh -vvv user@host

ainsi que le contenu de /etc/ssh/sshd_config sur le serveur.

commente la dernière ligne de ton sshd_config (ou remplace jluc par jl).

De rien, tu peux modifier ton premier message et ajouter [résolu] au début du titre.
