Salut,
Trois jours que je bataille, recherches sur la toile infructueuses.
Pour l’heure je peux me connecter sur le distant en simple utilisateur.
ssh -l mon_user@x.x.x.xMais l’accès root met interdit. Chose qui n’était pas auparavant.
J’ai tout remis à plat.
- local et distant.
rm ~/.ssh
rm /root/.ssh
J’ai ensuite recréer deux paires de clés privé/public (rsa et dsa) dans /home/loreleil/.ssh.
J’ai copier les clés /home/loreleil/.ssh/id_rsa.pub sur le distant /home/mon_user/.ssh/authorized_keys.
Le tout en mode rescue. C’est pour l’heure le seul accès root que je possède.
Les droits sur le dédié.

Les droits en local.
