dnssec-policy change from ZSK/KSK to CSK failed (bogus DNSSEC for zone)

2023-06-02 Thread Sebastian Wiesinger
Hi, I recently moved from auto-dnssec to dnssec-policy and after the switch I tried to change a zone from an RSA ZSK/KSK to an ECDSA CSK. When I changed the dnssec-policy from rsa to ecdsa-csk the old keys immediately got removed which lead to a bogus DNSSEC for the zone. I was expecting a rollov

BIND9 DNSSEC algorithm rollover for inline-signed zone

2016-10-06 Thread Sebastian Wiesinger
Hello, is there a guide for an algorithm rollover with BIND9 for an inline-signed zone? I want to roll from RSA to ECDSA but I'm unable to find a good guide for it. I already looked at the ISC DNSSEC Guide but it doesn't seem to cover that the RRSIGs made by the new keys need to be published befor

NSEC TTLs

2014-11-24 Thread Sebastian Wiesinger
Hello, I use BIND 9.9.5 with inline-signing and noticed that the NSEC records have different TTLs. I can't really explain why there is a difference. A few of the NSEC records have TTL 300 which is my SOA minimum (negative) TTL. This should be fine in regard to RFC4035 which states that every NSEC

Change in behaviour regarding ndots and searchlist

2014-09-15 Thread Sebastian Wiesinger
Hello, I noticed a change in the host tool in regard to how searches are done when there are >= "ndots" dots in the query. In the following case ndots is always nonexistant in the configuration. With bind 9.8 (Debian 1:9.8.4.dfsg.P1): $ host -d test.example Trying "test.example" Received 105 byt
