Thanks for your reply.

Maybe I am a skeptic, but I am not skeptic of just bind, skeptic about myself and any script that is generating zones, all I know that things go wrong... including things caused by my own mistakes.

1. I now run a Bind and other DNS servers. I am not sure if inter operate with each other correctly.

2. I found a bug on my zone generation script that has that at times not incremented the serial number on the master server and caused the servers to be out of sync. After being humbled by this and other problems (probably caused by me), I have decided that it would be best to have a testing method which is totally external to XFRs and not dependent on my good judgement.

Thank you for the git script I think it does what I need. 0.01% is acceptable.

To be blunt, I think you are being unreasonable - sort of a "radical skeptic" - about the software.

If you distrust the XFR bit of your DNS servers, why trust *any* of it? How do you know the DNS server isn't answering with garbage when it should be answering NODATA/NXDOMAIN? Or answering with correct values to you, but garbage 0.01% of the time to everyone else?

You don't know that, and you can never know that, so proceeding on this basis is futile.

Do you have grounds to *reasonably doubt* the functioning of your DNS software?

Anyway - in an attempt to be "helpful", even though I think it's a silly thing to do, here's a suggestion which queries every record in a zone verus a master file:

You could also canonicalise the zone file with "trusted" (ha ha) software then transfer it over a "trusted" protocol (ha ha), "freeze" the zone at the slaves having "trusted" that they will write to disk correctly, then use diff.

None of these solves the NODATA/NXDOMAIN or low-rate error problem, but they are, in principle, unsolvable.

Good luck - I doubt you'll find what you want though! ;o)

Cheers,
Phil
