## Name

dnssec-checkds — A DNSSEC delegation consistency checking tool.

## Synopsis

`dnssec-checkds` [`-l `domain``] [`-f `file``] [`-d `dig path``] [`-D `dsfromkey path``] {zone}

`dnssec-dsfromkey` [`-l `domain``] [`-f `file``] [`-d `dig path``] [`-D `dsfromkey path``] {zone}

## DESCRIPTION

dnssec-checkds verifies the correctness of Delegation Signer (DS) or DNSSEC Lookaside Validation (DLV) resource records for keys in a specified zone.

## OPTIONS

-f `file`

  If a `file` is specified, then the zone is read from that file to find the DNSKEY records. If not, then the DNSKEY records for the zone are looked up in the DNS.

-l `domain`

  Check for a DLV record in the specified lookaside domain, instead of checking for a DS record in the zone's parent. For example, to check for DLV records for "example.com" in ISC's DLV zone, use: dnssec-checkds -l dlv.isc.org example.com

-d `dig path`

  Specifies a path to a dig binary. Used for testing.

-D `dsfromkey path`

  Specifies a path to a dnssec-dsfromkey binary. Used for testing.
