[cobalt-users] Lame Server messages

["Terrance Dwyer" <td@xxxxxxxx>]

For a period of time each day, most recently a period of 75 minutes, my RaQ3
is asked to process bogus DNS requests for which it is not authoritative
resulting in Lame Server, Unexpected response, NS Query etc. error messages.
In a seventy five minute period yesterday I received nearly a thousand error
messages, mostly lame server.  There are many referring, NS and target IP's
listed in these error messages, no rhyme nor reason that I can fathom, and
none have anything to do with the sites on this server.

These bursts of DNS activity happen only once or twice a day generally.
They are not spread out throughout the day, they're concentrated.  The
duration of activity varies but the number of requests has skyrocketed in
the past 10 days.

I checked other posts. Some suggested turning recursion off in named, which
I did - the error messages stopped, but so did client email (oops). I can
turn the logging of this type of error message off but that seems a bit like
shooting the messenger.

The big question is this? Are there security implications here.  Is someone
trying to bring down named for some reason?   All responses are appreciated.

Thanks
