No, and there seems to be sparse documentation of the use of NSID in troubleshooting. I'm all ears. I would. however, like to restrict queries to inside networks/users and negate access to that data from the outside altogether. TIA, Bob Alan Clegg wrote: > Has anyone recommended doing debugging

It appears that receiving an NSID response depends on having server-id set in the options block. However, I'm seeing no way to restrict such queries. regards, Bob On Fri, Aug 28, 2015 at 7:48 AM, Bob McDonald wrote: > No, and there seems to be sparse documentation of the use of NSID in > troub

Re: Identify source of "rndc reconfig" command?

2015-08-28 Thread Robert Senger
Thank you all for your help! I found that the reconfig command was called by a script executed by wide-dhcpv6-client. In wheezy, this script was called once when the ipv6 address of the public ppp interface changed, in Jessie it was called every 30 minutes for whatever reason. Fixed that. Cheers,

DNSSEC ZSK rollover

2015-08-28 Thread Robert Senger
Hi all, after upgrading from Debian Wheezy to Jessie, the dnssec-tools package (including rollerd for automatic ZSK key rollover) is no longer available. So I've set up bind9 to do the signing: zone "mydomain.de" in {

What's in a name? :-) RFC 2308 said that the use of the last field of the SOA to set negative-caching TTL is "the new defined meaning of the SOA minimum field". So you can *call* it "minimum", but it is *actually* supposed to function as something else... Eventually I hope BIND will conform to

Negative-caching TTL and regular TTL have little to do with each other; it's not a reasonable assumption that one should stand in as a default for the other. I know analogies are frequently dangerous, but to me, that's kind of like saying that the amount of time that normally elapses between rep
