Bind zone transfer recategorises zone file?

fulhamfcboy · #1 (**permalink**) 11-08-2007

Hi,
I have a primary/slave Bind 9 setup running on a Solaris 10 platform. Everything is hunky dorey, except for when I make a zone file change and up the serial the file that is transferred to the slave looses all its comments, and the entries are place in alphabetical order.
I administer many Bind setup's, and I have never experienced anything like this in the past. Has anyone had any experience with this issue?
Thanks in advance, Tom.

You'll be performing an IXFR (or an AXFR depending on your setup) and you don't transfer the zone "file" verbatim.

Execute the following command, for example:

# dig axfr myzone.com @primary-server

You'll see what will be transferred during a full zone transfer.

This is normal behaviour. You don't administer zone files on slave DNS servers, so why would you need the comments? It'd just add unnecessary data to the transfer, which for nameservers authoritative for thousands of zones (with regular notifies) would be unacceptable.

Cheers,
ZB
