bind - forwarders

[Takaaki Iwamoto]

Hello, I am TAKAAKI. 

bind-8.2.3 are used in solaris2.5.1 environment, 
furthermore it is the composition of DNS outside inner DNS->Gateway->.
It has, when outside DNS falls with forwarding the name 
resolution of an external domain to outside DNS, and in the setup of inner DNS,
it was made to forward to secondly DNS in a provider side.

＜Inner DNS＞
option{
       forwarders {
                1.2.3.4;      // Outside DNS
                5.6.7.8;      // secondly in a provider side
                5.6.7.9;      // secondly in a provider side -2
        };
        forward only;
}

However, snoop | grep DNS, then the transfer are working only to secondly 
by the side of a provider in inner DNS, and most transfers to 
outside DNS were not generated. Although an order different knows 
the order of reference, it is strange that it is only secondly in provider. 
On a timeout, that is, a course, outside DNS is the nearest reason 
and it is hard to consider it. If secondly in provider side is commented out,
 it will come to forward to outside DNS perfectly. 
 
Although it thinks that there is more environment same probably,
what does it act as you?
