Estoy usando ubuntu 13.10, y el servidor ejecuta ubuntu 12.04. Había generado claves privadas y públicas usando ssh-keygen, puse id_rsa.pub en el lado del servidor y lo authorzied_keys
agregué de acuerdo con el método que encontré en Internet. Pero, todavía tengo que ingresar la contraseña mientras intento iniciar sesión. He configurado el directorio de inicio en 700, el directorio .ssh en 700, el archivo authorzied_keys en 600, y he comprobado el archivo sshd_config, y no pasó nada.
La información de depuración (con la opción -vvv) y sshd_config es la siguiente, y nada aparece en el archivo auth.log del servidor.
Incluso he actualizado openssh-server openssh-client tanto en el lado del cliente como del servidor.
¿Hay algo más que deba hacer? Gracias por cualquier información.
