Hello Eric,
thank you for giving Knot DNS a try.
its the zone file looks like the BIND one?
Knot DNS accepts zones in textual master files format (RFC 1035). So the
answer is yes, if you are using the zones in "text" format.
do I have to create it, may be I missed the zone
declaration in the Knot
manual?
With the posted configuration, you have to provide Knot DNS with
existing zone file. Just copy the zone file from BIND.
If you want to configure Knot DNS as a slave server (see bellow), you do
not need to provide zone file at all.
It is possible to do the master to master replication
from BIND to KNOT?
We do not have mechanism for master-master replication. But I think you
are looking for master-slave replication.
In fact, master and slave functionality is orthogonal: Master means that
your server is configured to allow outgoing zone transfers. Slave means
that your server pulls the zones from other master servers. And you can
also configure a server to act both as a master and slave.
So you will have to configure BIND to act as a master. This is done
using the `allow-transfer` zone config option.
And as for Knot DNS as a slave, check the `xfr-in` zone option. A well
described minimal example can be found in our documentation:
