Hi there, We had an issue last week (not in live) where we are testing the script to keep the new enum zone updated. The basic issue is that when we were trying to remove a AAAA record from a zone BINDs response to the update packet was FORMERR. So I wrote a small script to reproduce the behaviour: (See attached file: enum_AAAA_update) but on my local machine it works. The main difference is the version of Net::DNS, I am running 0.63 (as installed by ubuntu) and the other machine has 0.65. (We have confirmed that downgrading Net::DNS on the other machine to 0.63 results in the update working, and vice versa.) The dig formatted output was effectively identical in both cases. perl -v: This is perl, v5.10.0 built for x86_64-linux-gnu-thread-multi uname -a: Linux sion 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux Any way, it is not such a big issue for us as we are not using the latest version, but I thought that you should know about it. If there is any way in which I can be of any help, or if you need any more information, please just let me know. Cheers, Sion Lloyd

A packet dump of both transactions would be real useful. --Olaf On 2 mrt 2009, at 16:40, sion@nominet.org.uk via RT wrote: Show quoted text

Okay, attached are the outputs of the script while running v0.63 and v0.65 respectively. They are the result of using the ->string function on the update and reply objects. Is that what you wanted? Sion

Sorry, I've now had my morning coffee and realise that you probably mean a tcpdump of the transaction... Attached is a wireshark save of first the 0.63 traffic and then the 0.65 . There is a difference in the AAAA removal. Sion
