Hi Maren,
you should turn the explicit notification
both in bind and knot.
For Knot use "notify-out <slave1> <slave2>;" + "xfr-out
<slave1> <slave2>;"
See the documentation:
https://www.knot-dns.cz/static/documentation/html/configuration.html#master…
For Bind use "notify explicit;" + "also-notify;", see:
http://www.zytrax.com/books/dns/ch7/xfer.html#notify

Subject: [knot-dns-users] Two hidden masters - sending notifications to public slaves.
Hi,
We are setting up to do zone generations of two separate hidden masters
which will take turns on the zone generation.
Public/visible DNS servers "should" get notifies from both servers and
select the one with the with the highest serial number.
I am planning to run bind on one server and knot on the other. On bind i
have the issue that it would not send notifies to the name servers until
I turned on "notify-soa yes;". However I realise that his will only
notify one single DNS server and introduces a single point of failure.
Does Knot have any issues sending the notifies. How do I go about
getting this done?
Regards,
Maren

New subject: Two hidden masters - sending notifications to public slaves.
Thanks for the bind support.
So far I only have the bind based hidden master working. After
implemented these changes the zone transfers will take too long from the
time I do the rndc reload on the hidden master.
The knot based public servers are a bit quicker typically takes about 1
to 2 minutes.
The bind based public servers are random, I think they are typically
transfer on retry.
Once the transfer starts it is instantaneous.
I have no clue what it is doing that time... It is as if the notifies
are being stalled....
The master is behind a firewall and the NAT is a 1:1 so the source IP of
the Notifies and IXFR is correct.

Peter,
Thanks for your off list help.
Your suggest of using tcpdump lead me to find that the cause of the
problem. I had not taken into account that the notifies worked on UDP.
I had not enabled UDP on the firewall as I thought TCP would be sufficient.
After UDP notifies don't work on UDP the both bind and knot fail over to
TCP... the fail over is a bit lengthy.
Thank you all.

Hi,
better late than never, but the 1.5.x now uses TCP for notifications
as well because it's easier (and faster) to determine whether the
slave is operational, and provides a little bit of self-pacing for
zone distribution.
Best,
Marek
