Autenticación con llaves ssh

Mensaje por lyonn » Mar Dic 09, 2014 3:33 am

Buenas foristas,

Tengo un problema con la autenticación sin password con ssh. Ya revisé los permisos y son los correctos, el copiado de la llave también lo es, sin embargo, la única particularidad que tiene es que el $HOME del usuario es un volumen lógico. Estoy pensando en que pueda ser una opción de montaje, pero no estoy seguro.

La salida de mi intento de conexión es la siguiente:

No estoy seguro pero yo diría que es un tema de resolución de nombres. ¿Has probado a poner la ip en lugar del nombre SERVIDOR al conectarte?

he buscado por el error que te da y una de los primeros resultados a lo mejor te sirve:
