slave AXFR bind9

[Torsten Segner]

My first thoughts on this:

Has the slave received a notify from the master server?
Does the slave accept the notify?
What else is in the logs?

Could you please also provide your named configuration (options and the zone statement) of both master and slave?


Ciao
Torsten
