Search Again: General DNS, primary, secondary etc From: Scott Haneda Date: Tuesday, November 2, 2004 Time: 12:49:13 am I have queries on in QDNS, I am running this on my logs: tail -f /var/named/quickdns.log | grep -v 64.84.37 This is a backwards grep, so it shows all hits not in my subnet. Is it correct that only queries should show up for domains that I am doing DNS for? More or less, I see a ton of stuff in there, mostly all the slave zones. I have heard varying explanations of how DNS works in regards to this, I think that if you have 3 DNS servers, you really have no way of knowing which one will be asked for the record back. I was under the impression it was relatively random, which sort of makes sense, but at the same time makes me wonder why we call them Primaries when really they are more balanced across however many DNS machines you decide to have. If the above is not true, and I see more or less a steady stream of lookups coming for the handful of zones I am slaving, does that mean that something is wrong at the primary, that is for some reason or another can not be reached and I am taking the slack? I don't mind being a secondary, but if it means I am taking the brunt of the work, it just does not make sense to me. In the case above, I have recursive queries off so that should not be in the logs, so this is has to be coming from somewhere else. -- ------------------------------------------------------------- Scott Haneda Tel: 415.898.2602 <http://www.newgeo.com> Fax: 313.557.5052 <scott@newgeo.com> Novato, CA U.S.A.
