Hello all,
i stuck a little bit with the configuration of the new catalog zone feature in
knot dns 3.0.0.
The catalog zone replication is running quite well, but bootstrapping this
feature to replicate the config for zones wont work for me.
The zone name of the catalog zone is "zone.catalog".
The primary name server uses this config:
# Configuration export (Knot DNS 3.0.0)
zone:
- domain: "zone.catalog."
file: "%s"
notify: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
acl: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
catalog-role: "interpret"
catalog-template: "catalog-zone-template"
- domain: "dom-siew9tho.invalid."
The zone has this content:
[zone.catalog.] zone.catalog. 60 NS
nshp.frank.REDACTED.DOM.
[zone.catalog.] zone.catalog. 60 SOA nshp.frank.REDACTED.DOM. hostmaster.REDACTED.DOM.
1601540072 16384 2048 1048576 2560
[zone.catalog.] id-ies3eidiev4ooquahgoh.zone.catalog. 0 PTR dom-siew9tho.invalid.
[zone.catalog.] version.zone.catalog. 0 TXT "2"
Adding the following config to the primary works:
conf-begin
conf-set zone.domain "dom-siew9tho.invalid."
conf-commit
zone-begin dom-siew9tho.invalid.
zone-set dom-siew9tho.invalid. @ 60 SOA nshp.frank.REDACTED.DOM.
hostmaster.REDACTED.DOM. 1 16384 2048 1048576 2560
zone-set dom-siew9tho.invalid. @ 60 NS nshp.REDACTED.DOM.
zone-commit dom-siew9tho.invalid.
Query one of the secondaries (ns1) gives me:
error: (no such zone found) [dom-siew9tho.invalid.]
The config of ns1:
# Configuration export (Knot DNS 3.0.0)
template:
- id: "catalog-zone-template"
storage: "/var/lib/knot/zones"
file: "%s"
semantic-checks: "on"
dnssec-signing: "off"
serial-policy: "unixtime"
kasp-db: "/var/lib/knot/kasp-db"
zone:
- domain: "zone.catalog."
file: "%s"
master: "nshp.frank.REDACTED.DOM"
acl: "nshp.frank.REDACTED.DOM"
catalog-role: "interpret"
catalog-template: "catalog-zone-template"
I'm sure i miss one or more parts and/or i have a serious misunderstanding of
the bootstrapping setup for this feature.

Hi Frank,
yes, we need to clarify some misunderstandings.
First of all, generating/updating catalog zone according to primary
server configuration (that means: you change configuration e.g. by
'knotc conf-set', and the catalog zone would be updated automatically),
is not implemented yet in Knot DNS 3.0. This will be
'catalog-role:generate' in some of the future versions. For now, you can
only create and update the catalog zone by yourself, probably by similar
means as you are used to create/update the primary server's
configuration file.
I can see that you, at the primary server, configured the zone
dom-siew9tho.invalid. by both configuration file and catalog zone,
creating a conflict. Probably Knot warned you about this in the log.
The expected usage of current implementation of catalog zone is that,
you put the list of member zones only in the catalog zone, and not
mention them in neither primary's nor secondary's configuration file.
Both servers will interpret the same catalog zone. Just configure the
templates carefully, so that the primary will be a "master" for the
member zones, and the secondary a "slave".
I hope I made it somewhat clearer,
Mit herzlichen Grüßen,
Libor

Hello Libor,
thanks for the fast and clarifying response.

Ok, the version dot 0 problem ;-)

This was on of the trail and error steps. My first assumption was exactly
this, that you do not need to add the new zone via "conf-set zone.domain ...".
I will remove that from the config.
The expected usage of current implementation of
catalog zone is that, you put
the list of member zones only in the catalog zone, and not mention them in
neither primary's nor secondary's configuration file. Both servers will
interpret the same catalog zone. Just configure the templates carefully, so
that the primary will be a "master" for the member zones, and the secondary a
"slave".
Ok, so my showstopper seems to be the missing parts of master/notify and acl
entries in the template "catalog-zone-template"?
How do i query the config of the member zones, except to query the catalog zone?
The acl/remotes on primary and secondary are set:
primary:
template:
- id: "catalog-zone-template"
storage: "/var/lib/knot/zones"
file: "%s"
notify: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
acl: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
semantic-checks: "on"
dnssec-signing: "off"
serial-policy: "unixtime"
kasp-db: "/var/lib/knot/kasp-db"
- id: "default"
global-module: "mod-cookies/default"
storage: "/var/lib/knot/zones"
file: "%s"
semantic-checks: "on"
dnssec-signing: "off"
serial-policy: "unixtime"
kasp-db: "/var/lib/knot/kasp-db"
zone:
- domain: "zone.catalog."
file: "%s"
notify: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
acl: [ "ns1.frank.REDACTED.DOM", "ns2.frank.REDACTED.DOM" ]
catalog-role: "interpret"
catalog-template: "catalog-zone-template"
secondary (ns1/ns2):
template:
- id: "catalog-zone-template"
storage: "/var/lib/knot/zones"
file: "%s"
master: "nshp.frank.REDACTED.DOM"
acl: "nshp.frank.REDACTED.DOM"
semantic-checks: "on"
dnssec-signing: "off"
serial-policy: "unixtime"
kasp-db: "/var/lib/knot/kasp-db"
- id: "default"
global-module: "mod-cookies/default"
storage: "/var/lib/knot/zones"
file: "%s"
semantic-checks: "on"
dnssec-signing: "off"
serial-policy: "unixtime"
kasp-db: "/var/lib/knot/kasp-db"
zone:
- domain: "zone.catalog."
file: "%s"
master: "nshp.frank.REDACTED.DOM"
acl: "nshp.frank.REDACTED.DOM"
catalog-role: "interpret"
catalog-template: "catalog-zone-template"
After that, i try to create new zone:
root@nshp:~# su -c "/usr/bin/knotc zone-read
zone.catalog" knot
[zone.catalog.] zone.catalog. 60 NS nshp.frank.REDACTED.DOM.
[zone.catalog.] zone.catalog. 60 SOA nshp.frank.REDACTED.DOM. hostmaster.REDACTED.DOM.
1601550797 16384 2048 1048576 2560
[zone.catalog.] id-41dc0b92-e73d-5112-ad4d-dc362d6fd993.zone.catalog. 0 PTR zone.check.
[zone.catalog.] id-iechaag4deo9kogahfee.zone.catalog. 0 PTR dom-watooc9i.invalid.
[zone.catalog.] version.zone.catalog. 0 TXT "2"
root@nshp:~# export DOM="dom-watooc9i.invalid"
root@nshp:~# cat<<EOZ | su -c /usr/bin/knotc knot
zone-begin ${DOM%.}.
zone-set ${DOM%.}. @ 60 SOA nshp.frank.REDACTED.DOM. hostmaster.REDACTED.DOM. 1 16384
2048 1048576 2560
zone-set ${DOM%.}. @ 60 NS nshp.frank.REDACTED.DOM.
zone-commit ${DOM%.}.
EOZ
error: [dom-watooc9i.invalid.] (no such zone found)
error: (no such zone found) [dom-watooc9i.invalid.] @ 60 SOA nshp.frank.REDACTED.DOM.
hostmaster.REDACTED.DOM. 1 16384 2048 1048576 2560
error: (no such zone found) [dom-watooc9i.invalid.] @ 60 NS nshp.frank.REDACTED.DOM.
error: [dom-watooc9i.invalid.] (no such zone found)
What i'm missing? My understanding was, the adding a PTR rr will create a new
zone with the referenced catalog-template "catalog-zone-template", that i'm
able to add directly rr's to this zone. But, as you can see, this failed.
I hope I made it somewhat clearer,
Absolutly, yes ;-)

There is a error in the line. It should be:
id-ies3eidiev4ooquahgoh.zones.zone.catalog. 0 PTR dom-siew9tho.invalid.
zones is required there.

Hello Tuomo,
that does the trick!
I have read over this "*.zones.<catalog zone name>".
Thanks alot.
