Zone Transfer question / problem

[thedaver]

I have a Master and Two Slaves running Bind9 9.2.2 on (RH7.3) linux. Bind9s were compiled in the same way, and chrooted. All are answering queries properly.

Slave1 seems to receive zone transfers from the Master immediately when I -HUP the Master's named.

Slave2 seems to not get the transfer initiation from the Master, or doesn't accept it, because it does not get the immediate zone xfer (IXFR).

However, if I delete the corresponding BAK zone files from the Slave2 and restart the named service, it transfers the zones from Master correctly. I know this isn't entirely related, but it shows that zone transfers are working, but that IXFRs are not.

The kicker is that both Slaves are using the exact same 'named.conf', written on Slave1, copied to Slave2.

I know that zone files have a TTL, but I thought that when the Master announced the new zone serial number that the Slaves were "obligated" to take the transfer.

Slave2 was recently added as a named NS to the domains

Sorry for the long post, but I'm at a loss on where to start debugging this. '-d 3' on named startup doesn't reveal any thing. There are no errors during startup or operation on any of the 3 boxes.

Is it possible to misconfigure a zone's SOA or something that would confuse this process????

Thanks,
D.

what happens when you do:

nslookup -q=ns yourdomain.com IP_of_master_DNS?

It may be setupm, but do you actually see both secondaries w/their *proper* IPs?
