Hello BIND users
I have a very strange problem with AXFR. We are using a master and a
secondary DNS Server with an internal and an external view. Depending
on the source address the secondary server will get the internal or
external view for zone transfer.
Everything is working correct so far except only one specific zone file
won't get transferred. In the external view there are about 70 zones
defined. Every zone will get transferred except one and only one won't.
Therefor there can't be a problem with the firewall.
Then I scaled down the seconday DNS server to just about 2 zones and
again: this specific zone file won't get transfered even the master
said "AXFR started" and "AXFR ended" for this particular zone. On
the secondary server I'll get "giving up: timed out".
To test zone transfer by DIG I shut down the internal IP interface
so the AXFR request used the external IP interface for the zone transfer
and everything was ok (zone transfer succeeded).
I also checkd the zonefile against nonASCII chars. Everything looks
correct. I'm realy confused (by the way: we are still using BIND-0.9.5)
Do you have any idea ... ?
Is the problem zone larger than the ones that are not a problem? If so
it may be a MTU problem, or even a firewall that does things differently
based on packet sizes.
