NAME

       kea-dhcp4 - DHCPv4 server in Kea

SYNOPSIS

       kea-dhcp4   [-v]   [-V]   [-W]  [-d]  [-c  config-file]  [-t  config-file]  [-p  server-port-number]  [-P
       client-port-number]

DESCRIPTION

       The kea-dhcp4 daemon provides the DHCPv4 server implementation.

ARGUMENTS

       The arguments are as follows:

       -v     Displays the Kea version.

       -V     Displays the extended Kea version.

       -W     Displays the configuration report.

       -d     Enables the debug mode with extra verbosity.

       -c config-file
              Specifies the configuration file with the configuration for the DHCPv4 server. It may also contain
              configuration entries for other Kea services.

       -t config-file
              Checks the configuration file and reports the first error, if any. Note that  not  all  parameters
              are  completely  checked;  in  particular, service and control channel sockets are not opened, and
              hook libraries are not loaded.

       -T config-file
              Checks the configuration file and reports the first error,  if  any.   It  performs  extra  checks
              beyond  what  -t  offers,  such  as establishing database connections (for the lease backend, host
              reservations  backend,  configuration  backend,  and  forensic  logging  backend),  loading   hook
              libraries, parsing hook-library configurations, etc. It does not open UNIX or TCP/UDP sockets, nor
              does  it  open  or rotate files, as any of these actions could interfere with a running process on
              the same machine.

       -p server-port-number
              Specifies the server port number (1-65535) on which the server listens. This is useful for testing
              purposes only.

       -P client-port-number
              Specifies the client port number (1-65535) to which  the  server  responds.  This  is  useful  for
              testing purposes only.

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://kea.readthedocs.io.

       Kea   source   code   is   documented   in    the    Kea    Developer's    Guide,    available    at    ‐
       https://reports.kea.isc.org/dev_guide/.

       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.

HISTORY

       The b10-dhcp4 daemon was first coded in November 2011 by Tomek Mrugalski.

       In mid-2014, Kea was decoupled from the BIND 10 framework and became a standalone DHCP server. The DHCPv4
       server binary was renamed to kea-dhcp4. Kea 1.0.0 was released in December 2015.
