Slave DNS doesn't update..

[bshah at citadon.com]

Hi,

I have a DNS BIND 9.1.3 running on Solaris 8 as Master servers. Now I
installed the second DNS Server on Solaris 8 (BIND 9.1.3) and setup as
a Slave to both master DNS. However If I change the Zone file on master
and increment the SOA no it doesn't propagate to Slave DNS but if I
stop/start named (restart named) it does. Is there a configuration by
which it does transfer Zone automatically after updating the SOA serial
no? Also does dynamic update (allow-update tag) will help? I have TTL
to 1 Day. Am I missing anything here? I have also listed Slave DNS NS
entry in Zone example.com.

Here is my sample named.conf file...



Master:

options {

        directory "/var/named";

        pid-file "/etc/named.pid";

        allow-query { any; };

        allow-transfer {xx.xx.xx.xx ; }; //Slave DNS IP

        notify yes;
        also-notify {xx.xx.xx.xx; } //Slave DNS IP

zone "example.com" {

                type master;

                file "master/internal/example.com";



Slave:

options {

        directory "/var/named";

        pid-file "/etc/named.pid";

        allow-query { any; };



zone "example.com" {

                type slave;

                file "slave/internal/example.com";

                masters { xx.xx.xx.xx; }; // Master DNS IP



Any help/pointer will be greatly appreciated.

TIA
