rndc.conf error

[Bind Users]

Hi all     

I try to configure the /etc/rndc.conf but found errors.

- syntax error :

/etc/rndc.conf:11: syntax error near '<string>'
rndc: /etc/rndc.conf: failure


     1  key rndc_key {
     2      algorithm "hmac-md5";
     3      secret "xxxxxxxx";
     4  };
     5
     6  options {
     7            default-server localhost;
     8            default-key rndc_key;
     9  };
    10
    11  controls {
    12     inet 127.0.0.1 allow { localhost; } keys { rndc_key; };
    13  };

thanks in advance.
