Re: Transfer delays
As per the other answers I've seen posted, such a delay is often caused by notifies not reaching the slave from the master. In such a case, you would not expect a delay of a fixed time, but rather delays over a limited range of times, e.g. up to 15 minutes. A notify is a kind of DNS query, normally UDP. Can you do any kind of DNS query from the master to the slave? Specifically to/from the server's addresses that are being used by bind? A firewall or network ACL could be preventing all queries from master to slave, thus might block notifies. The zone transfer, in contrast, is a TCP query from slave to master, and could work even if UDP queries from master to slave are blocked. As per the answers I've seen posted, you also can look at notify-specific issues: either the master or the slave could be configured in such a way as to prevent the sending or receiving of them. Both can have logs of notifies sent/received, which you can use to eliminate this as your issue.

Also do you have allow-notify ACL restrictions on the secondary? ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

What may be useful, and I haven't seen suggested in the other replies so far, is to check your logs (and eventually packet-captures) to confirm that the master is indeed sending NOTIFY as expected, that the slaves are receiving NOTIFY, and whether the slaves are ignoring the NNOTIFY for some reason. /Niall ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Do you have NS records for slaves in the zone? Do you have corerect "master"
set up in the SOA?

List Members,
This is a new and quite basic install of BIND-9.
I am experiencing a 15 min delay from the time a zone file is updated and
reloaded w/ rndc and transferred to the slave server.
What could cause this delay. I am at a total loss. Please advise.
