Re: Seeking Advice on DNSSEC Algorithm Rollover

Hello. I don't think that bind trying to sign with non-existent key will do any harm - probably just warning. But it's simpler - change metadata of the key - set deletion time to the time you want the key to be deleted (like DS deletion time+TTL). Bind with auto-dnnsec allow re-reads the metadata

Hello Carsten, Thanks for your reply! about the FORMERR. This might be caused by a Firewall or other middlebox that truncates the large answer containing the NS record set for this domain. I see the same if I try to fetch the delegation NS records from the parent domain (microsoft.com) for part

Seeking Advice on DNSSEC Algorithm Rollover

2012-06-23 Thread Spain, Dr. Jeffry A.
I'm experimenting with rolling over my DNSKEYs from algorithm 7 to 8. The Bv9ARM doesn't discuss this procedure explicitly as far as I can tell, but section 4.9 presents some clues. I'd like to ask the experts on this list if the following procedure might accomplish an algorithm rollover cleanly
