Hello,
I've tried to upgrade from knot 2.3.3 to 2.4.0, but ran into a DNSSEC
related error, invalidating my DNSSEC-enabled zones :
2017-01-25T15:33:42 notice: [geekwu.org.] journal, obsolete exists, file '/var/lib/knot/external/geekwu.org.db'
2017-01-25T15:33:42 error: [geekwu.org.] DNSSEC, failed to initialize (not found)
2017-01-25T15:33:42 error: [geekwu.org.] zone event 'load' failed (not found)
stracing the error leads to this :
[pid 16787] open("/var/lib/knot/external/keys/policy_\\x06policy.json", O_RDONLY) = -1 ENOENT (No such file or directory)
I have some policy files in /var/lib/knot/external/keys:
-rw-r--r-- 1 knot knot 320 janv. 26 2016 policy_default.json
-rw-r--r-- 1 knot knot 320 janv. 26 2016 policy_default_rsa.json
-rw-r--r-- 1 knot knot 320 juin 14 2016 policy_ecdsa.json
>From where these \\x06policy may come ?
Thanks,

Dear Knot Resolver users,
CZ.NIC is proud to release a new release of Knot Resolver.
The team has worked very hard to bring:
- reworked DNSSEC Validation, that fixes several know problems
with less standard DNS configurations, and it is also a solid
base for further improvements
- optional EDNS(0) Padding support for DNS over TLS
- support for debugging DNSSEC with CD bit
- DNS over TLS is now able to create ephemeral certs on the runtime
(Thanks Daniel Kahn Gilmore for contributing to DNS over TLS
implementation in Knot Resolver.)
- configurable minimum and maximum TTL (default 6 days)
- configurable pseudo-random reordering of RR sets
- new module 'version' that can call home and report new versions
and security vulnerabilities to the log file
This release also fixes bugs, most notable ones:
- The resolver was setting AD flag when running in a forwarding
mode. Thanks Stéphane Bortzmeyer for reporting this issue!
- We now correctly return RCODE=NOTIMPL on meta-queries and
non IN class queries
- Fix crash in hints module when hints file was empty
- Fix non-lowercase hints
We also have a new LRU implementation under the hood.
That's it! Thank you for using Knot Resolver. And if you are
not using it yet, please give it a try.

Dear Knot DNS users,
CZ.NIC is proud to release the 2.4.0 release of Knot DNS. This release
contains many improvements over 2.3.x release of Knot DNS.
The Knot DNS 2.4.x is the new stable branch. Starting from this release
we are going to support current stable (2.4.x) and previous stable (2.3.x)
branches, and at the same time we are deprecating previous Knot DNS 1.6.x
release.
Now the new features we are so excited about!
* We have a new journal to store zone changes, it's key features are:
- all journals for all zones are in a single LMDB database
(defaults to storage/journal; 1G size)
- the occupied space is measured per zone
- old changesets get preserved after zone flush until we run out of space
- if zone flushing is disabled and journal gets full, it tries to free up
space by merging older changesets
- all changes are done by transactions, resulting in always-consistent DB
(but some mutexes still necessary for opening DB && for keeping zone
contents consistent with journal)
- kjournalprint provides a way to list zones in journal
- old journal is automatically imported, but the configuration needs to be
updated manually
* Thanks to qp-trie (originally proposed by Tony Finch) adapted to Knot DNS
we have much lower memory consumption when Knot DNS is used with many
zones
* The zone timers and zone events have been refactored and improved
* The SOA query and transfer now shares the TCP connection
* There's a new statistics module for traffic measurements
There are also several other bugfixes and improvements related to transfers,
timers and other areas.
And that's it! Thank you for using Knot DNS. And we are really looking
forward to your feedback.

Hi,
can someone please give me any explanation (or command) how my domain
registrator got from this record what i give him:
liberland.cz. 3600 DNSKEY 257 3 13
ei9T3egqng+nlAHeNfF6BzggGCyvS2lU5ih2BZuvkzFGxkBdUJ0blgSiW5iYIROvAEHQv5Ls3sNPA9JIt8iRjg==
this record:
liberland.cz. 17999 IN DS 21107 13 2
9405F3324FDCE3F0CC4E5D94CBFB5D8A4F211E3010D447B5FD73765F9EEC20EB
???
I want sign child zones but I can't find where i get hash
,,9405F3324FDCE3F0CC4E5D94CBFB5D8A4F211E3010D447B5FD73765F9EEC20EB"
And algorithm in RFC:
https://tools.ietf.org/html/rfc4034#section-5.4
digest = digest_algorithm( DNSKEY owner name | DNSKEY RDATA);
"|" denotes concatenation
DNSKEY RDATA = Flags | Protocol | Algorithm | Public Key.
doesn't help me :-/
Thanks and regards,
Jakub

Hola,
As recently a variety of people claimed to me that 'running DNSSEC is
not scary'.... I was like, lets try again after having tried it ~10
years ago and it failing miserably.
DNSSEC auto-maintain style looks to be better; still not as nice as
running dual-nsd's in master mode; but we'll live with those moving parts.
It ran fine for a bit, till I noticed the signatures of the zone had
expired and noticed the master simply did not bother to update the sigs
anymore. So much for 'automatic' mode.
Restarting it caused a nice crash:
Debian provided jessie-backports 2.3.1-1~bpo8:
```
knotd[6679]: *** Error in `/usr/sbin/knotd': double free or corruption
(out): 0x00007f4244042e80 ***
```
Then was like... lets try the latest edition:
Debian provided unstable 2.3.2-1:
```
knotd[11892] general protection ip:7fb8f7f0f218 sp:7fb8ce1cc3b0 error:0
in libc-2.24.so[7fb8f7e98000+195000]
````
yes, that is on a newer libc, hence different style error message it seems.
The 2.3.1 edition was able to report:
```
error: [example.com] changes from journal applied 1 -> 1 (invalid parameter)
````
before crashing out, the 2.3.2 just borks out.
Unfortunately there are no dbgsym packages for those editions, thus
can't easily dig what goes wrong where without having to resort to
manually building it all.
I could also not find a way to signup to:
https://gitlab.labs.nic.cz/users/sign_in
to be able to file a ticket about this.
Any extra details that one should be providing outside of the above
(link to that list is welcome ;) )
Should I attempt knot-nightly?
Greets,
Jeroen

Dear Knot DNS users,
CZ.NIC is proud to release a new version of Knot DNS. This is mainly
bug fix release, but there are some small improvements included as
well.
There are few fixes related to timers and DNSSEC. We have also fixed
double free in journal code, and memory leak in kzonecheck. All domains
are now fully-qualified in the logs and there's a new utility to print
journal contents - kjournalprint.
We would also like to invite everyone to migrate from Knot DNS 1.6.x
to the current stable Knot DNS 2.x.x release.
And that's it! Thank you for using Knot DNS. And we are really looking
forward to your feedback.

Hi,
I am just about to create some SPF records for my domain, and it seems I can't
do it the right way.
The record should look like
preissler.co.uk. 3600 TXT "v=spf1 mx -all"
and I am creating it with knotc, interactive or not doesn't matter.
knotc zone-begin preissler.co.uk
knotc zone-unset preissler.co.uk preissler.co.uk. 3600 TXT "v=spf1 mx -all"
knotc zone-commit preissler.co.uk
this then gives me
[preissler.co.uk.] preissler.co.uk. 3600 TXT "v=spf1" "mx" "-all"
which is wrong.
If I use "'" it's the same. Then using
knotc zone-set preissler.co.uk preissler.co.uk. 3600 TXT v=spf1 mx -all
I get
error: (name does not belong to the zone) [preissler.co.uk] preissler.co.uk. 3600 TXT v=spf1 mx -all
I am aware I could just edit the zonefiles or use DDNS probably... but surely, there must be a way?
Regards
Thomas

Dobry den,
pokousim se rozbehnout knot-2.3.1 (kompilace z ports) na jailu na FreeBSD 11
Problem je v tom, ze knot neodpovida na udp portu a to i kdyz to zkousim
primo v jailu.
Jine porty napr. smtp primo z jailu funguji, mozna je to jenom nejaka
chyba v nastaveni
knot-2.3.1
Toto vsechno jsem zkousel:
* netcat z jailu na stejny jail udp port 53 - funguje
* netcat z hostu do jailu udp 53 - funguje
* netcat z jineho hostu na host kde bezi jail udp 53 - funguje
Takto to dopadne primo z jailu ale i z jineho hosta:
# kdig liguros.net aaaa @ns1.liguros.net
;; WARNING: response timeout for 2001:470:cadd:1::5@53(UDP)

Toto vidim v pfctl -s states

relevantni rules
pass in inet6 proto tcp from any to 2001:470:cadd:1::5 port = domain
flags S/SA keep state
pass in inet6 proto udp from any to 2001:470:cadd:1::5 port = domain
keep state
takto jsou jeste nastavene rdr na ip4 adresu jailu:
rdr pass on em0 inet proto tcp from any to any port = domain -> 10.0.0.5
rdr pass on em0 inet proto udp from any to any port = domain -> 10.0.0.5
rdr pass on lo1 inet proto tcp from any to any port = domain -> 10.0.0.5
rdr pass on lo1 inet proto udp from any to any port = domain -> 10.0.0.5
i kdyz nemyslim si, ze je to pf vina, protoze se do jailu napr. pomoci
netcat "dostanu"
ns jail:
ns:/usr/ports/dns/knot2@[22:44] # sockstat
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root knotd 1650 7 dgram -> /var/run/logpriv

Poradte mi prosim, jak danou vec dale debugovat.
Predem mockrat dekuji.

I am trying to get knot 2.3.1 (from ports) working in a jail, but I am
unable to connect to the udp port even when trying directly from jail.
Using netcat from within jail and also from other machines gets through
into the jail. I don't think it is pf's fault.
How can I debug this a bit more?
Thank you for your help
Pavol
