Re: Clients Matching Multiple Views

2014-04-09 Thread Jason Brandt
I faced a similar situation when setting up my servers. The way I handled it (correctly or not) was to built the zones in the internal view as master, and then the external view slaved to the internal master. That way you can simply update your internals, and the external side automatically popul

I have ours setup with AD as a stub, and then point all our clients to our bind servers as resolvers. Works well. On Tue, Apr 8, 2014 at 5:08 AM, Bryan Harris wrote: > Hello all, > > We have a sort of private DNS such that servers can lookup zones that > don't actually exist in the real, publi

Thanks guys. I appreciate the input. I don't want to derail the list much though, as this is supposed to be more BIND than Cisco :) At this point my BIND installation seems to be stable, so we'll call it case closed. We do plan on replacing our firewalls in the near future, so hopefully we won'

nately our MRTG isn't setup to track firewall CPU, so I can't say for sure. Thanks, Jason On Wed, Mar 26, 2014 at 4:02 AM, Sam Wilson wrote: > In article , > Jason Brandt wrote: > > > For now, I've disabled DNS inspection on our firewall, as it is an > ancient &g

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

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 patching.

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 h
