Wouldn't this ruin dynamic updates from the DHCP servers? These updates need to be sent to the master. I could of course configur™e "allow- update-forwarding".

Maybe I could just AXFR from the running slave and use the output as zone files on the master. As far as I can see this should Just Work™. > My program nsdiff (http://dotat.at/prog/nsdiff) is useful for copying > dynamic zones from from an existing master to a new master without > faffing around with `rndc freeze`. Nice. :-) Perfect for copying changes without touching the files. I'll take a thorough look at it. -- Peter Rathlev _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
