ldns-keyfetcher - retrieve the DNSSEC DNSKEYs for a zone
SYNOPSIS
ldns-keyfetcher [ OPTIONS ] DOMAIN
DESCRIPTION
ldns-keyfetcher is used to retrieve the DNSKEYs of a zone.
First it finds all authoritative nameservers of the zone by tracing it from the root down. All authoritative nameservers are then queried
(using TCP) for the DNSKEY RRset of the zone apex. If the results are all the same, the key resource record set is printed.
OPTIONS -4 Only use IPv4
-6 Only use IPv6
-h Show a help text and exit
-i Insecurer mode; there will only be one query for the DNSKEYS. There will not be crosschecking of all authoritative nameservers.
-v verbosity
Set the verbosity level. The following levels are available:
0: default, only print the DNSKEY RRset found, or an error on failure.
1: Show the nameservers that are queried
2: Show more info on what is checked
3: Show the intermediate results (authority and dnskey rrsets)
4: Print the answer packets that are returned
-r file
Use file as the root hints file, should contain A records in presentation format. The default is /etc/named.root. You can get this file
from http://www.internic.net/zones/named.root.
-s Don't print the keys to stdout, but store them in files.
The filenames will be of the format K<file>.+<alg>.+<keytag>.key

ldns-walk(1) General Commands Manual ldns-walk(1)NAME
ldns-walk - Retrieve the contents of a DNSSEC signed zone
SYNOPSIS
ldns-walk [ OPTION ] ZONE
DESCRIPTION
ldns-walk is used to retrieve the contents of a DNSSEC signed zone. It does this through NSEC-walking (following the chain of NSEC
records) and 'guessing' the next non-existent owner name for each NSEC.
Note that it might get stuck on some wildcard records when used through a caching forwarder. This problem can be circumvented by querying
the authoritative nameserver directly (with the @ argument).
Of course the nameserver that is used must be DNSSEC-aware.
OPTIONS -4 Use only IPv4.
-6 Use only IPv6.
-f Do a 'full' zone walk; by default, ldns-walk will only show the names, and types present at those names. If this option is given,
all resource records will be printed.
-s name
Start the walk with this owner name. Useful when continuing the walk for a large zone.
-v verbosity
Verbosity level [1-5].
@ nameserver
Send the queries to this nameserver.
BUGS
The full zone walk function is not complete yet, it does not correctly print delegation records
