我主从bind不一样，发现rndc会有问题!救救！急

9pts

主的：www1
version: 9.5.0-P2 (hello!)
number of zones: 48
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is ON
recursive clients: 14/0/1000
tcp clients: 0/100
server is up and running
从的：www2
version: 9.5.0-P2 (hello!)
number of zones: 43
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is ON
recursive clients: 13/0/1000
tcp clients: 0/100
server is up and running
从的：www3
version: 9.6.0 (hello!)
CPUs found: 8
worker threads: 8
number of zones: 45
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 11/0/1000
tcp clients: 0/100
server is up and running
结果发现在www3无法rndc -s www1 reload 服务器 ,在www2上可以rndc -s www1 reload 服务器
在www1可以同时rndc  -s www2 reload   rndc -s www3 reload
请问是bind 版本问题吗
在www3上rndc -s www3 reload 可以正常
但在www3.上无法rndc -s www1 ，出错如下
rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.

以上出错信息可以排除the key is invalid.这个提示错误
请高手帮忙，为什么高版本bind 下会有这样问题

肯定是www3上的问题，主要检查/etc/rndc.conf文件
