Hello, list! I have split view on my name-servers (master and slave), for internal and external clients i have zone with similar names, but different content. Part of config named.conf on master: view "internal" { match-clients { myclients; }; recursion yes; match-recursive-only yes

Hi, Maybe this can help you. First you need two network interfaces with diferent ip. At the internal view declaration add transfer-source 192.168.11.x; ( has to be different from your public/external) In the zone statement, you must specify the private IP address of your slaves, at allow-transf

"if a root zone is not defined in named.conf" I wonder if you really do NOT want to ever hit root zones you could make your own entry in named.conf that points to localhost for root zone and thereby avoid hitting any real root? -Original Message- From: bind-users-bounces+jlightner=w

Zone refresh checks and zone transfer requests are not recursive queries. With match-recursive-only, the view cannot act as a master to any slave. You might want to consider a hidden master that does not have this option set. Regards, Chris Buxton BlueCat Networks On Dec 21, 2011, at 1:54 AM, K

No, that's not correct. You can use TSIG keys to differentiate between views, without using separate interfaces. However, this will not solve the problem -- removing match-recursive-only will solve the problem. Regards, Chris Buxton BlueCat Networks On Dec 21, 2011, at 2:23 AM, Gelo wrote: > H
