Zone transfer not working

[Michael Bleyer]

Hi,
my zone transfer does not work and I would appreciate some help.
Setup:

Master: (80.190.246.175)
acl partners { 85.214.66.29; };
zone "linksabbieger.net" in {
        type master;
        file "linksabbieger.net.zone";
        allow-query { any; };
        notify yes;
        allow-transfer { partners; };
};

Slave: (85.214.66.29)
zone "linksabbieger.net" in {
        type slave;
        file "slaves/linksabbieger.net.zone";
        allow-query { any; };
        masters { 80.190.246.175; };
        allow-notify { 80.190.246.175; };
};

So afaik, this setup should work. But I get error messages on master and
slave:
Master says:
Oct  5 08:27:24 ombelico named[20052]: security: client
::ffff:85.214.66.29#40793: zone transfer 'linksabbieger.net/IN' denied

Slave says:
Oct  5 08:10:40 h1038919 named[28752]: transfer of 'linksabbieger.net/IN'
from 80.190.246.175#53: failed while receiving responses: REFUSED
Oct  5 08:10:40 h1038919 named[28752]: transfer of 'linksabbieger.net/IN'
from 80.190.246.175#53: end of transfer

I don't understand why it fails. It seems not to be a directory permission
issue like some of the other folks have (I checked and the error message
doesn't say permission denied).

The only weird part that bugs is that the messages on the master when I
start named say that port 53 is in use:
Oct  5 10:12:04 ombelico named[741]: binding TCP socket: address in use
Oct  5 10:12:04 ombelico named[741]: listening on IPv4 interface eth0,
80.190.246.175#53

Afaik named uses tcp 53 to do transfers? I don't know why the port would
be in use, I keep getting that log entry when I restart bind.

Any hints appreciated.
