kea-admin - Shell script for managing Kea databases¶

Synopsis¶

kea-admin [command] [backend] [-u database username] [-p database password] [-n database name] [-d scripts directory] [-4 | -6] [-o output file] [-v]

Description¶

kea-admin is a shell script which offers database maintenance. In particular, it features database initialization, database version checking, and database schema upgrade.

Arguments¶

command

Specifies the command to be issued to the servers. It can be one of the following:

lease-init: Initializes a new lease database, which is useful during the first Kea installation. The database is initialized to the latest version supported by the version of the software.
lease-version: Reports the lease database version. This is not necessarily the same as the Kea version, as each backend has its own versioning scheme.
lease-upgrade: Conducts a lease database upgrade. This is useful when migrating between old and new Kea versions.
lease-dump: Dumps the contents of the lease database (MySQL and PostgreSQL backends) to a text file. The content of the file consists of comma-separated values (CSV) where each line in the file contains all of the values for a single lease. The first line of the file is a header line containing the column names.

backend

Specifies the backend type. Currently allowed backends are: memfile, mysql, and pgsql.

-u|--user username

Specifies the username when connecting to a database. If not specified, the default value of keatest is used.

-p|--password password

Specifies the password when connecting to a database. If not specified, the default value of keatest is used.

-n|--name database-name

Specifies the name of the database to connect to. If not specified, the default value of keatest is used.

-d|--directory script-directory

Specifies the override scripts directory. That script is used during upgrades, database initialization, and possibly other operations. If not specified, the default value of (prefix)/share/kea/scripts/ is used.

-o|--output output_file

Specifies the file to which the lease data will be dumped. Required for lease-dump.

-v|--version

Prints the kea-admin version and quits.

-4

Directs kea-admin to lease-dump the DHCPv4 leases. Incompatible with the -6 option.

-6

Directs kea-admin to lease-dump the DHCPv6 leases. Incompatible with the -4 option.

Documentation¶

Kea comes with an extensive Kea Administrator Reference Manual that covers all aspects of running the Kea software - compilation, installation, configuration, configuration examples, and much more. Kea also features a Kea Messages Manual, which lists all possible messages Kea can print with a brief description for each of them. Both documents are available in various formats (.txt, .html, .pdf) with the Kea distribution. The Kea documentation is available at https://kb.isc.org/docs/kea-administrator-reference-manual .

Kea source code is documented in the Kea Developer’s Guide. Its online version is available at https://jenkins.isc.org/job/Kea_doc/doxygen/.

The Kea project website is available at https://kea.isc.org.

Mailing Lists and Support¶

There are two public mailing lists available for the Kea project. kea-users (kea-users at lists.isc.org) is intended for Kea users, while kea-dev (kea-dev at lists.isc.org) is intended for Kea developers, prospective contributors, and other advanced users. Both lists are available at https://lists.isc.org. The community provides best-effort support on both of those lists.

ISC provides professional support for Kea services. See https://www.isc.org/kea/ for details.
