CNAME to an external domain

2014-03-25 Thread Ian Braun
Hello, We have a bind server (v9.6) that's hosts mydomain.com. I'm trying to create a CNAME for host.mydomain.com to point to host.otherdomain.com. I don't host otherdomain.com. My entry currently reads: sipIN CNAME sip.otherdomain.com. But my DNS server isn't resolving it. It

High recursive client counts

2014-03-25 Thread Jason Brandt
We recently migrated to BIND for our internal resolvers, and since the migration, we are experiencing periods of high recursive client counts, which will at times cause the BIND server to quit responding. As a workaround, I've been able to point the BIND server to a forwarder, bypassing the root

Hi Jason, I've experienced similar things in the past on 9.8. Since then we've moved to the latest 9.9, but don't think this is at all version specific (that said, you could obviously try upgrading). I don't have an exact solution for you, but some ideas of things to check and personal

Mike, I appreciate your insight here. We are indeed on virtual systems, using enterprise grade hardware as well. I will be doing more investigation today, to see if I can duplicate the behavior, which I have been able to do recently. Your VM vs Physical point is the thing that got me head

Bind 9.9.1 forward zone local

Hello. I have a problem with forwarding zone local to ISP resolvers. My config is: options { directory /tmp; disable-empty-zone .; }; zone . { type slave; masters { 192.0.32.132; 193.0.14.129;}; masterfile-format text; file /etc/bind/db.root;

Cathy, Thank you for your comments. I will continue to investigate, it helps to have avenues to look down though. As far as build version, we are aware that we aren't at current stable release. However we've tried to stick to the distro release as much as possible, to help streamline

I would imagine your issue is a lack of an NS delegation in the root zone you are slaving. If you load a parent and then try to forward a child of that parent you must have a delegation in the parent. The delegation doesn't have to match the forwarders but it must exist. On Mar 25, 2014 1:57 PM,

Mark, That's a very good question, and something we had thought of as a possibility as well. I hadn't seen any good information in relation to entropy, so I'll check into your link. We had noticed that on other things as well, due to the virtual environment, but nothing that caused performance
