Hi,  I create a new bind slave (the third one) using webmin and slave clustering off one master.  I do the first replication and it all looks fine.  However I notice that the named.conf on the slave has some of the other slaves as well as the master defined in the "masters {" section for each zone as per example below (note .12 is the only master).  Similarly if I create a new master zone then all of the slaves get some of  the slaves as well as the master in their ….. as previously stated.
Unfortunately it would appear that the slaves can try to replicate of each other at times.  Firewall rules will prevent this from ever happening.  Is this behvaiour typical and can i configure it so it never happens. 
I know I can use sed to delete the undesirable lines from the file if required or perhaps a template would be the way to go but haven't tryed these yet.

zone "tctest4.co.nz" {
        type slave;
        masters {
                10.245.110.12;
                10.245.110.132;
                10.245.110.140;
                };
        file "/var/named/slaves/tctest4.co.nz.hosts";
        };

Many thanks for any help.
