Subject: problem with domain and sub-domain configuration
X-FuHaFi: 0.68000000000000005



Hello I have one domain

test.com with namserver ns.test.com (10.0.0.1)

and a subdomain

cr.test.com with nameserver ns.cr.test.com (10.1.0.1)


my problem is that if I update hostnames inside test.com zone
updates are not seen by cr.test.com nameserver

Do you update the serial number in the zone file before you save the file? What you describe seems indicative of no update. The serial must be bumped once per update. This indicates that the zone has been changed and a reload is necessary. After you save the zone file, execute a "rndc reload <zone>" to make named reload the zone.

Hope this helps.

they are seen if I restart named on cr.test.com


actually on ns.cr.test.com I have the following directive

zone "test.com" IN {
        type forward;
        forward only;
        forwarders { 10.0.0.1; };
};

but when I update the father zone test.com for example I add an ip
address,
the update is not seen by cr.test.com nameserver and I have to restart named and after that it works. So that clients using cr.test.com nameserver cannot see updates to test.com domain ip addresses.

I do not know how to fix this problem unless I configure cr.test.com
to
be slave of test.com
but i did not want to do so.

any hints ?

thank you

Rick
