kea-lfc (8) - Linux Manuals

ARGUMENTS

The arguments are as follows:

-d

Verbose mode sets the logging level to debug. This is primarily for development purposes in stand-alone mode.

-v

version causes the version stamp to be printed.

-V

Version causes a longer form of the version stamp to be printed.

-W

Display the configuration report.

-h

Help causes the usage string to be printed.

-4 | -6

The protocol version of the lease files, must be one of 4 or 6.

-c

Configuration file including the configuration for kea-lfc process. It may also contain configuration entries for other Kea services. Currently kea-lfc gets all of its arguments from the command line, in the future it will be extended to get some arguments from the config file.

-p

PID file - When the kea-lfc process starts it attempts to determine if another instance of the process is already running by examining the pid file. If one is already running the new process is terminated. If one isn't running it writes its pid into the pid file.

-x

Previous or ex lease file - When kea-lfc starts this is the result of any previous run of kea-lfc. When kea-lfc finishes it is the result of this run. If kea-lfc is interrupted before completing, this file may not exist.

-i

Input or copy of lease file - Before the DHCP server invokes kea-lfc it will move the current lease file here and then call kea-lfc with this file.

-o

Output lease file - The temporary file kea-lfc should use to write the leases. Upon completion of writing this this file it will be moved to the finish file (see below).

-f

Finish or completion file - Another temporary file kea-lfc uses for bookkeeping. When kea-lfc completes writing the output file it moves it to this file name. After kea-lfc finishes deleting the other files (previous and input) it moves this file to previous lease file. By moving the files in this fashion the kea-lfc and the DHCP server processes can determine the correct file to use even if one of the processes was interrupted before completing its task.

DOCUMENTATION

Kea comes with an extensive Kea User's Guide documentation that covers all aspects of running the Kea software - compilation, installation, configuration, configuration examples and many 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 typically available in various formats (txt, html, pdf) with your Kea distribution. The on-line version is available at http://kea.isc.org/docs/.

Kea source code is documented in the Kea Developer's Guide. It's on-line version is available at http://kea.isc.org. Please follow Developer's Guide link.

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

MAILING LISTS AND SUPPORT

There are two mailing lists available for 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 http://lists.isc.org. The community provides best effort type of support on both of those lists.

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