debian下的bind 9有问题

coldcoffee

/etc/init.d/bind9 restart
Stopping domain name service...:rndc: connect failed: connection refused
.
Starting domain name service...:.

怎么回事？

我的named.conf如下：
include "/etc/bind/named.conf.options";

zone "." {
type hint;
file "/etc/bind/db.root";
};


zone "localhost" {
type master;
file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};

zone "lygg.org" IN {
type master;
file "lygg.org.zone"
allow-update { none; };
};

zone "0.168.192.in-addr.arpa" IN {
type master;
file "0.168.192.arpa";
allow-update { none; };
};

include "/etc/bind/named.conf.local";
