10.3: Strange DNS behavior and workaround
Authored by: vogunaescht on Dec 10, '03 11:17:49AM

i advise to read the manpage of lookupd.

lookupd -flushcache does the job.

Yes, that works to clear lookupd's cache, but doesn't change the fact that Panther is not following the standard practice (or the Jaguar method) for DNS lookups...

10.3: Strange DNS behavior and workaround

True. Is there a proxy involved that might cache DNS entries? Another possibility is to run bind locally as a caching-only nameserver.

10.3: Strange DNS behavior and workaround
Authored by: DavidMaxWaterman on Jan 08, '04 02:01:40AM

We run our local domain in a similar manner to the original poster, and we have a local dns server to resolve local names.

I am the only one using a Mac and I am the only one that has problems using our dns server. The problem I see is that my initial attempts to load a web page fail; the second and subsequent attempts fail. If I don't visit that page for a while, the failure happens again, again only for the first attempt.

I used tethereal on the server to compare requests made by my Mac with requests made from other OSes (w2k and xp); the traces are here :

http://reality.sgiweb.org/maxw/tmp/Apple/3519742/

if anyone cares to look. To summarise, Mac makes this sort of sequence of requests :

http://reality.sgiweb.org/maxw/tmp/Apple/3519742/eth1-214-OSX-02-dns.txt

1 0.000000 192.168.0.214 -> 192.168.0.1 DNS Standard query A news.google.com
5 0.705145 192.168.0.214 -> 192.168.0.1 DNS Standard query A news.google.com
9 1.410272 192.168.0.214 -> 192.168.0.1 DNS Standard query A news.google.com
12 2.115540 192.168.0.214 -> 192.168.0.1 DNS Standard query A news.google.com.jingmei.org

It tries the 'news.google.com.jingmei.org; domain before the server has even responded to the first request.

I filed a bug (3519742) with Apple on this, but it does not seem to be getting any attention :( It's really messing me up; and is embarressing when all the various Microsoft OSes work fine.

Max.

10.3: Strange DNS behavior and workaround

Hi there!

Sometimes different external domains get routed to my default domain, e.g. www.apple.com goes to www.apple.com.mydomain.com

What could be the reason for this?
The author of the article says this is a standard behaviour. But why this happens and what can I against caching the false ip
