I´ve soved the problem 1) The NS record points to the external (valid) ip address, so the nortify won´t work and 2) even restarting the salve server, the zone does not transfer, so i put a 15min time for refresh (default was 3 hs) and the transfer occurs the number 1 above was not changed. Only waiting, works! tanks ------------- Segue mensagem original! ------------- Additionally, do you have the Debian box listed as an NS record in the zone file? If the secondary servers aren't listed in the zone file, the secondary won't ever be notified of changes, and won't try to transfer the zone. Same goes for the aforementioned serial number...if it's not updated (the secondary server still needs to be listed as an NS record), the secondary won't try to pull the updated zone.
