Hi,

As requested:

(I can resolve the domain, i whoissed the domain to see which nameservers
are responsible for this,
 and they all respond correctly to me....)

What could be wrong?

Hi Remko and Stephane,

Since you were both kind enough to reply to my emails last night, I at
least know that you will receive this. As you can see from the attached,
however, it seems that posts to the group are not being delivered.

Given that the isc.org domain cannot see my domain and that the domain
admins for isc.org must be experts on dns, it seems a great opportunity
to find out more about the problem I am experiencing.

Could you please forward this message to either the group, and if you
know who the admins are perhaps directly to them as well.

Many Thanks,

  Geoff

Now I'm going to sound like an idiot, but here goes...

How would I see incoming and outgoing packets? Do I need to use
something like Ethereal?

The only log file I can find with dns messages in is /var/log/messages.
This has startup and shutdown messages in and message pairs like:

Jan 28 07:36:09 dns named[13745]: client 82.68.177.94#34976:
updating zone 'w-sys.co.uk/IN': update failed: 'RRset exists   (value
dependent)' prerequisite not satisfied (NXRRSET)
Jan 28 07:36:09 dns named[13745]: client 82.68.177.94#34650: update
'w-sys.co.uk/IN' denied

Do I need to look somewhere else, or perhaps switch on some level of
debug?
