NAME

     dnssec-tools.conf - Configuration file for the DNSSEC-Tools programs.
 
 

DESCRIPTION

This file contains configuration information for the DNSSEC-Tools programs. These configuration data are used if nothing else has been specified for a particular program. The conf.pm module is used to parse this configuration file.

The recognized configuration fields are described in the Configuration Records section below. Some configuration entries are optional and a configuration file need not contain a complete list of entries.

A line in the configuration file contains either a comment or a configuration entry. Comment lines start with either a '#' character or a ';' character. Comment lines and blank lines are ignored by the DNSSEC-Tools programs.

Configuration entries are in a keyword/value format. The keyword is a character string that contains no whitespace. The value is a tokenized list of the remaining character groups, with each token separated by a single space.

True/false flags must be given a 1 (true) or 0 (false) value.

Configuration Records

The following records are recognized by the DNSSEC-Tools programs. Not every DNSSEC-Tools program requires each of these records.

admin-email

The email address for the DNSSEC-Tools administrator.

algorithm

The default encryption algorithm to be passed to dnssec-keygen.

archivedir

The pathname to the archived-key directory.

default_keyrec

The default keyrec filename to be used by the keyrec.pm module.

endtime

The zone default expiration time to be passed to dnssec-signzone.

entropy_msg

A true/false flag indicating if the zonesigner command should display a message about entropy generation. This is primarily dependent on the implementation of a system's random number generation.

keyarch

The path to the DNSSEC-Tools keyarch command.

keygen

The path to the dnssec-keygen command.

keygen-opts

Options to pass to the dnssec-keygen command.

kskcount

The default number of KSK keys that will be generated for each zone.

ksklength

The default KSK key length to be passed to dnssec-keygen.

ksklife

The default length of time between KSK roll-overs. This is measured in seconds.

This value is only used for key roll-over. Keys do not have a life-time in any other sense.

lifespan-max

The maximum length of time a key should be in use before it is rolled over. This is measured in seconds.

lifespan-min

The minimum length of time a key should be in use before it is rolled over. This is measured in seconds.

random

The random device generator to be passed to dnssec-keygen.

rndc

The path to the rndc command.

roll_loadzone

A flag indicating if rollerd should have the DNS daemon reload zones.

roll_logfile

The log file used by rollerd.

roll_loglevel

The default logging level used by rollerd. The valid levels are defined and described in rollmgr.pm.

roll_sleeptime

The number of seconds rollerd must wait at the end of each zone-checking cycle.

roll_username

The username that rollerd will be run by. The name will be converted to its associated uid, and the effective uid of the rollerd process will be set to that uid. This may be given as a user name or a uid.

savekeys

A true/false flag indicating if old keys should be moved to the archive directory.

usegui

Flag to allow/disallow usage of the GUI for specifying command options.

zonecheck

The path to the named-checkzone command.

zonecheck-opts

Options to pass to the named-checkzone command.

zonesign

The path to the dnssec-signzone command.

zonesign-opts

Options to pass to the dnssec-signzone command.

zonesigner

The path to the DNSSEC-Tools zonesigner command.

zskcount

The default number of ZSK keys that will be generated for each zone.

zsklength

The default ZSK key length to be passed to dnssec-keygen.

zsklife

The default length of time between ZSK roll-overs. This is measured in seconds.

This value is only used for key roll-over. Keys do not have a life-time in any other sense.

Sample Times

Several configuration fields measure various times. This section is a convenient reference for several common times, as measured in seconds.

     3600        - hour
     86400       - day
     604800      - week
     2592000     - 30-day month
     15768000    - half-year
     31536000    - year
