ubuntu – Dig为外部查询返回“status：REFUSED”？

# dig ungl.org

但是当我从同一数据中心的另一台服务器运行它时,我会收到：

# dig @87.98.167.208 ungl.org

我的这个域名的区域文件是

$ttl 38400
ungl.org.       IN  SOA r29901.ovh.net. mikey.aol.com. (
                201003121

www             IN  A   188.165.34.72

而named.conf.options是默认的：

options {
    directory "/var/cache/bind";

    // If there is a firewall between you and nameservers you want
    // to talk to,you may need to fix the firewall to allow multiple
    // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

    // If your ISP provided one or more IP addresses for stable 
    // nameservers,you probably want to use them as forwarders.  
    // Uncomment the following block,and insert the addresses replacing 
    // the all-0's placeholder.

    // forwarders {
    //  0.0.0.0;
    // };

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { ::1; };
    listen-on { 127.0.0.1; };
    allow-recursion { 127.0.0.1; };
};

named.conf.local：

//
// Do any local configuration here
//

// Consider adding the 1918 zones here,if they are not used in your
// organization
// include "/etc/bind/zones.rfc1918";

zone "eugl.eu" {
         type master;
         file "/etc/bind/eugl.eu";
         notify no;
};


zone "ungl.org" {
         type master;
         file "/etc/bind/ungl.org";
         notify no;
};

服务器正在运行Ubuntu 9.10和Bind 9,如果有人能为我解释这一点,那会让我很开心！

谢谢
