Slave Server Notify

[Mark Andrews]

In message <560485.29733.qm at web36105.mail.mud.yahoo.com>, Brad Beckenhauer writ

> Running Centos 5.5 with bind-9.3.6-4.P1.el5_4.2 (from the Centos repo) and I'
> m unable to get a slave server to retrieve the zone file from the master.
> 
> The master nameserver has a public ip address, the slave sits behind a firewa
> ll / NAT on a private ip address.
> 
> When I update a zone file on the master server, the slave receives a 'notify"
>  (see log below) and (if I'm interpreting the log correctly) requests the zon
> e file from the master nameserver, but ages out and logs the message "failed 
> address not available".
> 
> In the named.conf file, I have the logging severity is set to "debug 9" for d
> ebugging purposes and I'm still not able to figure out why the zone will not 
> transfer.

> In the slaves named.conf file I have:
> - logging severity is set to "debug 9"  (Temporary for debugging).
> - allow-notify with the master nameservers ip address.
> - transfer-source with the Public IP of the Private nameserver (the slave is 
> behind a Nat/Firewall).
> - allow-transfer with the ip address of the master nameserver.
> 
> Question: What is the "failed address" that bind is attempting to lookup so I
>  can get the zone files to transfer?
