SYNOPSIS

use Net::DNS::SEC::Tools::dnssectools;
dt_adminmail($subject,$msgbody,$recipient);
$zspath = dt_cmdpath('zonesigner');
$ftype = dt_findtype($path);
$seconds = dt_parse_duration("0w3d1h10m20s")
$rrset = dt_parse_zonefile(file => 'example.com');

DESCRIPTION

The dnssectools module provides a general set of methods for use with DNSSEC-Tools utilities.

INTERFACES

The interfaces to the dnssectools module are given below.

dt_adminmail(subject,msgbody,recipient)

This routine emails a message to the administrative user listed in the DNSSEC-Tools configuration file.

dt_adminmail() requires two parameters, both scalars. The subject parameter is the subject for the mail message. The msgbody parameter is the body of the mail message.

A third parameter, recipient, may be given to specify the message's recipient. If this is not given, then the recipient will be taken from the admin-email record of the DNSSEC-Tools configuration file. If recipient is ``nomail'', then no message will be sent and success will be returned.

Return values:

        1 - the message was created and sent.
        0 - an invalid recipient was specified.

It relies on the the following dnssec-tools.conf configuration parameters:

admin-email

The email address that the mail should come from.

mailer-type

Should be one of: sendmail, smtp, qmail. This option is not required and will default to trying sendmail and qmail to deliver the mail. If mailer-server is set to a defined value but mailer-type is not, then mailer-type will default to

mailer-server

The server, if admin-mail is set to smtp, that the mail should be delivered to.

dt_cmdpath(command)

This routine returns the path to a specified DNSSEC-Tools command. command should be the name only, without any leading directories. The command name is checked to ensure that it is a valid DNSEC-Tools command,

Return values:

        The absolute path to the command is returned if the command
        is valid.
        Null is returned if the command is not valid.

dt_filetype(path)

This routine returns the type of the file named in path. The rollrec and keyrec records contained therein are counted and a type determination is made.

Return values:

        "keyrec" -  At least one keyrec record was found and no
                    rollrec records were found.
        "rollrec" - At least one rollrec record was found and
                    no keyrec records were found.
        "mixed" -   At least one rollrec record and at least one
                    keyrec record were found.
                    This is most likely an erroneous file.
        "unknown" - No rollrec records nor keyrec records
                    were found.
        "nofile"  - The specified file does not exist.

dt_parse_duration(string)

This routine translates a duration given in ``1w2d3h4m5s'' format and returns the equivalent number of seconds, or undef if the duration has an invalid format.

dt_parse_zonefile(options)

This routine parses a given zone file using the configured zone file parser and returns an array reference containing the RRs. The options hash is the same as for Net::DNS::ZoneFile::Fast.

The zone parser to be used depends on the setting of the zonefile-parser configuration value. If this is not set, then the Net::DNS::ZoneFile::Fast zone parser will be used.
