NAME

pdnsutil - PowerDNS record and DNSSEC command and control

SYNOPSIS

pdnsutil [OPTION]... COMMAND

DESCRIPTION

pdnsutil (formerly pdnssec) is a powerful command that is the operator-friendly gateway into DNSSEC and zone management for PowerDNS. Behind the scenes, pdnsutil manipulates a PowerDNS backend database, which also means that for many databases, pdnsutil can be run remotely, and can configure key material on different servers.

OPTIONS

-h, --help: Show summary of options
-v, --verbose: Be more verbose.
--force: Force an action
--config-name <NAME>: Virtual configuration name
--config-dir <DIR>: Location of pdns.conf. Default is /etc/powerdns.

COMMANDS

There are many available commands, this section splits them up into their respective uses

DNSSEC RELATED COMMANDS

Several commands manipulate the DNSSEC keys and options for zones. Some of these commands require an ALGORITHM to be set. The following algorithms are supported:

rsasha1
rsasha1-nsec3-sha1
rsasha256
rsasha512
ecdsa256
ecdsa384
ed25519
ed448

activate-zone-key ZONE KEY-ID: Activate a key with id KEY-ID within a zone called ZONE.
add-zone-key ZONE [KSK,ZSK] [active,inactive] [published,unpublished] KEYBITS ALGORITHM: Create a new key for zone ZONE, and make it a KSK or a ZSK (default), with the specified algorithm. The key is inactive by default, set it to active to immediately use it to sign ZONE. The key is published in the zone by default, set it to unpublished to keep it from being returned in a DNSKEY query, which is useful for algorithm rollovers. Prints the id of the added key.
create-bind-db FILE: Create DNSSEC database (sqlite3) at FILE for the BIND backend. Remember to set bind-dnssec-db=*FILE* in your pdns.conf.
deactivate-zone-key ZONE KEY-ID: Deactivate a key with id KEY-ID within a zone called ZONE.
disable-dnssec ZONE: Deactivate all keys and unset PRESIGNED in ZONE.
export-zone-dnskey ZONE KEY-ID: Export to standard output DNSKEY and DS of key with key id KEY-ID within zone called ZONE.
export-zone-ds ZONE: Export to standard output all KSK DS records for ZONE.
export-zone-key ZONE KEY-ID: Export to standard output full (private) key with key id KEY-ID within zone called ZONE. The format used is compatible with BIND and NSD/LDNS.
generate-zone-key {KSK,ZSK} [ALGORITHM] [KEYBITS]: Generate a ZSK or KSK to stdout with specified algorithm and bits and print it on STDOUT. If ALGORITHM is not set, ECDSA256 is used. If KEYBITS is not set, an appropriate keysize is selected for ALGORITHM. Each ECC-based algorithm supports only one valid KEYBITS value: For ECDSA256 and ED25519, it is 256; for ECDSA384, it is 384; and for ED448, it is 456.
import-zone-key ZONE FILE {KSK,ZSK}: Import from FILE a full (private) key for zone called ZONE. The format used is compatible with BIND and NSD/LDNS. KSK or ZSK specifies the flags this key should have on import. Prints the id of the added key.
publish-zone-key ZONE KEY-ID: Publish the key with id KEY-ID within a zone called ZONE.
remove-zone-key ZONE KEY-ID: Remove a key with id KEY-ID from a zone called ZONE.
set-nsec3 ZONE ['HASH-ALGORITHM FLAGS ITERATIONS SALT'] [narrow]: Sets NSEC3 parameters for this zone. The quoted parameters are 4 values that are used for the the NSEC3PARAM record and decide how NSEC3 records are created. The NSEC3 parameters must be quoted on the command line. HASH-ALGORITHM must be 1 (SHA-1). Setting FLAGS to 1 enables NSEC3 opt-out operation. Only do this if you know you need it. For ITERATIONS, please consult RFC 5155, section 10.3. And be aware that a high number might overload validating resolvers and that a limit can be set with max-nsec3-iterations in pdns.conf. The SALT is a hexadecimal string encoding the bits for the salt, or - to use no salt. Setting narrow will make PowerDNS send out "white lies" (RFC 7129) about the next secure record to prevent zone enumeration. Instead of looking it up in the database, it will send out the hash + 1 as the next secure record. Narrow mode requires online signing capabilities by the nameserver and therefore zone transfers are denied. If only the zone is provided as argument, the 4-parameter quoted string defaults to '1 0 0 -'. A sample commandline is: pdnsutil set-nsec3 powerdnssec.org '1 1 1 ab' narrow. WARNING: If running in RSASHA1 mode (algorithm 5 or 7), switching from NSEC to NSEC3 will require a DS update in the parent zone.
unpublish-zone-key ZONE KEY-ID: Unpublish the key with id KEY-ID within a zone called ZONE.
unset-nsec3 ZONE: Converts ZONE to NSEC operations. WARNING: If running in RSASHA1 mode (algorithm 5 or 7), switching from NSEC to NSEC3 will require a DS update at the parent zone!
set-publish-cds ZONE [DIGESTALGOS]: Set ZONE to respond to queries for its CDS records. the optional argument DIGESTALGOS should be a comma-separated list of DS algorithms to use. By default, this is 2 (SHA-256). 0 will publish a CDS with a DNSSEC delete algorithm.
set-publish-cdnskey ZONE [delete]: Set ZONE to publish CDNSKEY records. Add 'delete' to publish a CDNSKEY with a DNSSEC delete algorithm.
unset-publish-cds ZONE: Set ZONE to stop responding to queries for its CDS records.
unset-publish-cdnskey ZONE: Set ZONE to stop publishing CDNSKEY records.

TSIG RELATED COMMANDS

These commands manipulate TSIG key information in the database. Some commands require an ALGORITHM, the following are available:

hmac-md5
hmac-sha1
hmac-sha224
hmac-sha256
hmac-sha384
hmac-sha512

activate-tsig-key ZONE NAME {primary,secondary}: Enable TSIG authenticated AXFR using the key NAME for zone ZONE. This sets the TSIG-ALLOW-AXFR (primary) or AXFR-MASTER-TSIG (secondary) zone metadata.
deactivate-tsig-key ZONE NAME {primary,secondary}: Disable TSIG authenticated AXFR using the key NAME for zone ZONE.
delete-tsig-key NAME: Delete the TSIG key NAME. Warning, this does not deactivate said key.
generate-tsig-key NAME ALGORITHM: Generate new TSIG key with name NAME and the specified algorithm.
import-tsig-key NAME ALGORITHM KEY: Import KEY of the specified algorithm as NAME.
list-tsig-keys: Show a list of all configured TSIG keys.

edit-zone ZONE: Opens ZONE in zonefile format (regardless of backend it was loaded from) in the editor set in the environment variable EDITOR. if EDITOR is empty, pdnsutil falls back to using editor.
get-meta ZONE [ATTRIBUTE]...: Get zone metadata. If no ATTRIBUTE given, lists all known.
hash-password [WORK-FACTOR]: This convenience command asks for a password and returns a hashed and salted version, for use as a webserver password or api key. An optional scrypt work factor can be specified, in power of two, otherwise it defaults to 1024.
hash-zone-record ZONE RNAME: This convenience command hashes the name RNAME according to the NSEC3 settings of ZONE. Refuses to hash for zones with no NSEC3 settings.

set-kind ZONE KIND: Change the kind of ZONE to KIND (primary, secondary, native).
set-account ZONE ACCOUNT: Change the account (owner) of ZONE to ACCOUNT.
add-meta ZONE ATTRIBUTE VALUE [VALUE]...: Append VALUE to the existing ATTRIBUTE metadata for ZONE. Will return an error if ATTRIBUTE does not support multiple values, use set-meta for these values.
set-meta ZONE ATTRIBUTE [VALUE]...: Set zonemetadata ATTRIBUTE for ZONE to VALUE. An empty value clears it.
set-presigned ZONE: Switches ZONE to presigned operation, utilizing in-zone RRSIGs.
show-zone ZONE: Shows all DNSSEC related settings of a zone called ZONE.
