求助red hat 9下搭建dns辅助域名服务器出错

搭建的主dns可以正常工作。
辅助dns配置文件

zone "huting.com" IN {
type slave;
file "slaves/huting.com.zone";
masters{ 192.168.137.100; };
};

zone "137.168.192.in-addr.arpa" IN {
type slave;
file "slaves/huting.local";
masters{ 192.168.137.100; };
};
include "/etc/rndc.key";


主dns服务器配置文件：

zone "huting.com" IN {
type master;
file "huting.com.zone";
allow-update { none; };
allow-transfer { 192.168.137.150; };
};

zone "137.168.192.in-addr.arpa" IN {
type master;
file "huting.local";
allow-update { none; };
allow-transfer { 192.168.137.150; } ;
};

include "/etc/rndc.key";



在辅助dns服务器上看 [root@localhost named]# cat /var/log/messages | grep named

May 6 16:54:01 localhost named[3604]: dumping master file: slaves/tmp-XXXXk2Le89: open: file not found
May 6 16:54:01 localhost named[3604]: transfer of '137.168.192.in-addr.arpa/IN' from 192.168.137.100#53: failed while receiving responses: file not found
May 6 16:54:01 localhost named[3604]: transfer of '137.168.192.in-addr.arpa/IN' from 192.168.137.100#53: end of transfer

在主dns服务器上看[root@localhost named]# cat /var/log/messages | grep named

May 6 16:50:10 localhost named[3214]: client 192.168.137.150#32785: transfer of 'huting.com/IN': AXFR started
May 6 16:53:33 localhost named[3214]: client 192.168.137.150#32786: transfer of '137.168.192.in-addr.arpa/IN': AXFR started


不知道是那里出错了，请各位多多指教。
