HELP: slave DNS is not updating Zone FIle from Master


Hello all,

I am having a problem with my slave dns server ... it is not updating the zone files form my master DNS server. Does anybody know what my problem may be??

The Master works well on its own ... it responds to nslookups on valid hosts ... but using nslookup on the slave, for the same host, will fail.

I don't think its a huge error, it may be a small fix ... but I don't know what it may be, nor how to fix it.

Here its probably better if I clarify with some parameters mapped out ........ as well as the test I use to know somethings wrong (read below)

-----------------------------------------------------------------
Master 172.1.5.5
----------------------------------------------------------------

DNS State = Started!!
DNS Forwarder ip = 192.168.XX.X;
DNS Mode = Master
DNS Nameserver ip = 172.1.5.5
DNS Network = 172.1.0.0
DNS Netmask = 255.255.0.0
Domain Name = p.org
DNS Slave = 172.1.1.1

testperson@itsa255 ~ $ nslookup nsName.p.org
Server: 172.1.5.5
Address: 172.1.5.5#53

Name: nsName.p.org
Address: 172.1.55.55



-----------------------------------------------------------------------------------
Slave 172.1.1.1:
-----------------------------------------------------------------------------------

DNS State = Started!!
DNS ForwarderList = 192.168.XX.X;
DNS Mode = slave
DNS Nameserver ip = 172.1.1.1
DNS Network = 172.1.0.0
DNS Netmask = 255.255.0.0
DNS DomainName = itsadomain.org
DN[/b]S Master = 172.1.5.5

testperson@itsadomain ~ $ nslookup nsName.p.org
Server: 172.1.1.1
Address: 172.1.5.5#53

** server can't find NsName.p.org: NXDOMAIN

**************************************************************************************************** **********************

When I do the nslookup on the slave, it should still see the 172.1.55.55 address I assigned to my fake nsName host I added to the Master DNS, but it of course does not, even though my master does see it.

Thanks for your time

So these are the zones the master is loading...
Code:
general: info: zone 0.0.127.in-addr.arpa/IN: loaded serial 2005010100
general: info: zone 1.172.in-addr.arpa/IN: loaded serial 2006091105
general: info: zone localhost/IN: loaded serial 2005010100
general: info: zone p.org/IN: loaded serial 2006091108
...but yet it looks like the slave is requesting a zone be transfered from the master by the name of itsadomain.com. You loaded p.org on the master, not itsadomain.org, so the master is replying that its not authoritative (which is correct).
Code:
general: info: zone itsadomain.org/IN: refresh: non-authoritative
answer from master 172.1.5.5#53 (source 0.0.0.0#0)
