getdnskeys

NAME

getdnskeys - Manage lists of DNSKEYs from DNS zones.

SYNOPSIS

     getdnskeys [-i file] [-o file] [-k] [-T] [-t] [-v] [zones]
 
 

DESCRIPTION

getdnskeys manages lists of DNSKEYs from DNS zones. It may be used to retrieve and compare DNSKEYs. The output from getdnskeys may be included (directly or indirectly) in a named.conf file.

OPTIONS

-h

Gives a help message.

-i path

Reads {\it path} as a \path{named.conf} with which to compare key lists.

-k

Only looks for Key Signing Keys (KSK); all other keys are ignored.

-o file

Writes the results to {\it file}.

-T

Checks the current trusted key list from \path{named.conf}.

-t

Encloses output in needed \path{named.conf} syntax markers.

-v

Turns on verbose mode for additional output.

EXAMPLES

This \cmd{getdnskeys} will retrieve the KSK for example.com:

     getdnskeys -o /etc/named.trustkeys.conf -k -v -t example.com
 
 

This \cmd{getdnskeys} will check saved keys against a live set of keys:

     getdnskeys -i /etc/named.trustkeys.conf -T -k -v -t
 
 

This \cmd{getdnskeys} will automatically update a set of saved keys:

     getdnskeys -i /etc/named.trustkeys.conf -k -t -T -v
                -o /etc/named.trustkeys.conf
 
 

SECURITY ISSUES

Currently this does not validate new keys placed in the file in any way, nor does it validate change over keys which have been added.

It also does not handle revocation of keys.

It should prompt you before adding a new key so that you can always run the auto-update feature.
