Estoy tratando de descubrir por qué no puedo hacer que la autenticación de clave pública SSH funcione con el servidor UNIX de mi escuela. Obviamente no tengo acceso de root, pero adjunté salida SSH detallada y permisos de los directorios .ssh del cliente y del host, y ssh-copy-id que muestra que se cargó una clave. El contenido de los archivos id_rsa.pub del local y Authorized_keys del servidor coincide exactamente. ¿Qué necesito arreglar?
