YAKEYROLLD-CONF(5)

NAME

yakeyrolld.conf - configuration file for yakeyrolld(8).

SYNOPSIS

${SYSCONFDIR}/yakeyrolld.conf

DESCRIPTION

The configuration of yakeyrolld is consistent in a text file that can optionally include others. The general structure is a a sequence of containers: a sequence of lines of text starting with a <container-name> and ending with a </container-name>. Each line between these delimitters is in the form: variable-name value. The format of the value is determined by the type of the variable.

There are 7 types:

FQDN
     A fully-qualified domain name text string. e.g.: www.eurid.eu.

GID
     Group ID. (Can be a number or a name)

HOST(S)
     A (list of) host(s). A host is defined by an IP (v4 or v6) and can be followed by the word `port' and a port number. Elements of the list are separated by a `,' or a `;'.

INTEGER / INT
     A base-ten integer.

PATH / FILE
     A file or directory path. i.e.: "/var/plans".

STRING / STR
     A text string. Double quotes can be used but are not mandatory. Without quotes the string will be taken from the first non-blank charater to the last non-blank character.

UID
     User ID. (Can be a number or a name)

  STANDARD SECTIONS

There are 9 sections:

<yakeyrolld>

<channels>
     Description of the logger outputs.

It contains a list descriptions of user-defined outputs for the logger. Depending on the kind of output, the format is different.

The "name" is arbitrary and is used for identification in the <loggers>.
The "stream-name" defines the output type (i.e.: a file name, a program output or syslog).
The "arguments" are specific to the output type (i.e.: unix file access rights or syslog options and facilities).

    *   file output stream channel-name file-name access-rights (octal).

    *   pipe to a program channel-name "| shell command" channel-name "| path-to-program program arguments >> append-redirect"

    *   STDOUT, STDERR output stream channel-name stdout channel-name stderr

    *   syslog channel-name syslog syslog-facility

<loggers>
     Description of the logger outputs sources.

Sets the output of a pre-defined logger for yakeyrolld.

The format of the line is: logger-name output-filter comma-separated-channel-names

Filters are:
DEBUG7, DEBUG6, DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, DEBUG, INFO, NOTICE, WARNING, ERR, CRIT, ALERT, EMERG

Additionally, there are:

    *   ALL (or '*') meaning all the filters.

    *   PROD means all but the DEBUG filters.

    The defined loggers are:

    keyroll
         contains general messages about the keyroll

    dnssec
         contains messages about DNSSEC-related computations during the generation.

    system
         contains low level messages about the system such as memory allocation, threading, IOs, timers and cryptography, ...

    System operators will mostly be interested in the info and above messages of the keyroll and dnssec loggers.

EXAMPLES

Examples of containers defined for a configuration file.

*   Main

    1.  Config with includes

*   Channels

Logging output-channel configurations:

It contains a list of user-defined outputs for the logger.

The "name" is arbitrary and is used for identification in the <loggers>.
The "stream-name" defines the output type (i.e.: a file name, a program output or syslog).
The "arguments" are specific to the output type (i.e.: unix file access rights or syslog options and facilities).

    1.  Example: logging channels definition.

        <channels>
        #   name        stream-name     arguments
            keyroll     keyroll.log     0644
            dnssec      dnssec.log      0644
            system      system.log      0644
            all         all.log         0644
        </channels>

*   Loggers

Logging input configurations:

The "bundle" is the name of the section of yakeyroll being logged, sources are : database, dnssec, queries, server, stats, system, zone.
The "debuglevel" uses the same names as syslog.
Additionally, "*" or "all" means all the levels; "prod" means all but the debug levels.

The "channels" are a comma-separated list of channels.

    1.  Example logger configuration

        <loggers>
        #   bundle          debuglevel                          channels
            keyroll         prod                                keyroll,all
            dnssec          prod                                dnssec,all
            system          prod                                system,all
