Hi,
for benchmark purpose I need to find out how log it takes to sign zone
files in different sizes with different hardware. What is the best way
to find out the exact time the signing process takes?
Thanks!

Hi,
when signing a zone file I receive this error in the log:
"zone event 're-sign' failed (not enough space provided)"
Can you tell me what is the limiting factor here?
Thanks!

Hello,
Could you please clarify whether Knot can perform a zone transfer not
from the first master listed, but from the one that sent the NOTIFY? The
masters are configured in the following order:
remote:
- id: master
address: [ "192.168.58.151", "192.168.58.134" ]
When a NOTIFY is sent from |192.168.58.134|, the zone transfer is still
performed from |192.168.58.151|.
Here are the relevant log entries:
Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] notify,
incoming, remote 192.168.58.134@32888 TCP, serial 2006
Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] refresh, remote
192.168.58.151@53, remote serial 2006, zone is outdated
Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] IXFR, incoming,
remote 192.168.58.151@53 TCP, receiving AXFR-style IXFR
Apr 25 19:09:25 ubuntu knotd[2065]: info: [chacha.com.] AXFR, incoming,
remote 192.168.58.151@53 TCP, started
Thank you for your product and for your help!

Hi,
this happened to me for the second time, that https://dnsviz.net <https://dnsviz.net/> tells me:
| enfer-du-nord.net/CDNSKEY: The CDNSKEY RRset must be signed with a key that is represented in both the
| current DNSKEY and the current DS RRset. See RFC 7344, Sec. 4.1.
| enfer-du-nord.net/CDS: The CDS RRset must be signed with a key that is represented in both the current
| DNSKEY and the current DS RRset. See RFC 7344, Sec. 4.1.
I do not understand what that means.
#) I haven't modified my KSK for some time now
#) I did notify my parent zone about a modified list of nameservers (via registrar's web portal)
I am not absolutely sure if the latter is the cause for these error messages.
I 'fixed' that issue by re-uploading my unmodified KSK DNSKEY (via registrar's web portal).
Hmm, how can I fix that issue the right way?
Any hints are highly welcome,
Michael
Hi,
given the case that a ip6/xy block might be delegated to me by my ISP, I began investigating Knot DNS' functionality with regard to ip6.arpa.
Hereby I stumbled over the module synthrecord and do not really understand what it is used for.
From https://www.knot-dns.cz/docs/3.4/singlehtml/index.html#synthrecord-automati…
"Records are synthesized only if the query can't be satisfied from the zone."
Please excuse my ignorance, but why would/should/must one return something else than the following for hosts not in the zone?
kbn> host 2001:dead:beef::1
Host 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.f.e.e.b.d.a.e.d.1.0.0.2.ip6.arpa not found: 3(NXDOMAIN)
Any feedback is highly appreciated, thanks.
Regards,
Michael
Hi,
This is just a possible feature request. We’re planning on using Knot for user
hosted domains. To do that we’ll have to add and remove zones dynamically,
so we’ve enabled the config db.
What surprised us is that this means that the config file isn’t used at all anymore
(except you can use it to prime the config db).
As it is, we’ll have to embrace the config db, which makes our ansible playbook
more complicated. It’s easy to add a config file template in ansible, it’s more
complicated to issue `knotc conf-begin; knotc conf-set; knotc conf-commit` logic.
I wish knot was more like nsd, where you have the config file nsd.conf, but if
you add zones with `nsd-control addzone ….` it gets added to a seperate zonelist
file, which nsd reads on startup. It means we can have a static config file, but
still be able to add and delete zones dynamically.
nsd doesn’t have automatic DNSSEC key management and catalog zones in knot
are really easy to use, which is why we’re going with knot for this project. I just
wanted to lay it out there as an idea for the future :)

Hi Bill,
You can't mix a configuration database and a configuration file.
You can initialize a database with `knotc conf-init` or `knotc conf-import`.
Then if you start knotd, the database will be used for reading and persistent writing.
The configuration database format is a custom format using LMDB. It's not intended to be accessed externally!

For example, can I use the configuration file for directives like listen and template, then use the configuration database for storing individual zone settings? So far, it appears that knotd only uses one or the other. Furthermore, there doesn't seem to be any command to explicitly load or flush configuration from the database. If I start with the config file, I can initialize the database, but upon stopping knotd nothing seems to be saved to the database. I also don't see any documentation on tooling to inspect the database on disk. What is the file format of the database?

Hello!
In July 2024, in the Knot-DNS 3.3.8 release message, Daniel writes:
>I would like to ask users with hardware HSMs to send us the output of `keymgr <hsm_keystore_id> keystore-test`

We're now running Knot 3.4.4 against a Thales HSM (I have no details of the
actual device/model in use at this time) and I see the following data:
$ keymgr -c etc/knot.conf thales keystore-bench
Keystore id 'thales', type PKCS #11, threads 1
Algorithm Sigs/sec
RSASHA256 33
ECDSAP256SHA256 27
ED25519 n/a
ED448 n/a
My first reaction was "hmm, that's slow".
Is there a list (above URL isn't it) of comparable results which I could show
the HSM operators and/or is anybody willing to share their data?
Thanks & regards,
