Private & separate DNS domains

2014-04-08 Thread Bryan Harris
Hello all, We have a sort of private DNS such that servers can lookup zones that don’t actually exist in the real, public DNS, they just exist within our private NOCs. In addition, we have always had both Windows AD handling the Windows side of things and we have had BIND handling Linux. When

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

BIND behaviour when using multiple active ZSK's

2014-04-08 Thread Thomas Dupas
Hello All, we've stumbled upon a particularity with Bind 9.8 and 9.9 versions, and are wondering if anyone else already bumped into this. When using more than 1 active ZSK, in a bind auto-maintain scenario, BIND tends to lose control when renewing RRSIG’s. You experience this as sudden bursts in

Regardless of what you've been told, the resolvers ("nameserver"s) in /etc/resolv.conf are tried *in*sequence*, and if a valid response (where NXDOMAIN _is_ a valid response) is received from one resolver, none of the others are tried. So, I'm surprised that your mix-and-match-resolvers hack ac

What if no root servers?

2014-04-08 Thread Dean Gibson (DNS Administrator)
I'm interested in a special use-case, where (say, in an emergency), access to most of the Internet (and hence the root servers) is cut off. In this situation, there is an emergency connected network consisting of several domains, each with known nameserver IP addresses. The hosts in domain a
