Zone transfers between master and slave

NSD
1

I have NSD on FreeBSD 10.1 running successfully as a master. I'm trying to get it to transfer zones to a slave.

In nsd.conf on the master I have:

key:
         name: "sec1_key"
         algorithm: hmac-md5
         secret: "<secret>"

zone:

         name: "hostname.domain.tld"
         zonefile: "db.hostname.domain.tld"
         notify: <slave-IP> sec1_key
         provide-xfr: <slave-IP> sec1_key
         notify-retry: 10

In nsd.conf on the slave I have:

zone:
         name: "hostname.domain.tld"
         zonefile: "db.hostname.domain.tld"
         allow-notify: <master-IP> sec1_key
         request-xfr: AXFR <master-IP> sec1_key
key:
         name: "sec1_key"
         algorithm: hmac-md5
         secret: "<secret>"

I'm not seeing any slave zonefile showing up on the slave server. What should I look at next to troubleshoot?

TIA

Hello anonymous fongaboo (possibly Paul Bliss),

First of all, can you please identify yourself? Writing email messages
to the list without your name is the equivalent of talking to us with a
paper bag over your head. I, at least, find that impolite.

The NSD log? tcpdump? strace? A book on unix system administration?
