%description
DHCP (Dynamic Host Configuration Protocol) is a protocol which allows
individual devices on an IP network to get their own network
configuration information (IP address, subnetmask, broadcast address,
etc.) from a DHCP server. The overall purpose of DHCP is to make it
easier to administer a large network.

%description -l es.UTF-8
DHCP permite que hosts en una red TCP/IP soliciten y tengan sus
direcciones IP alocadas dinámicamente, permite también descubrir
información sobre la red en que están conectados. BOOTP provee una
funcionalidad similar, con ciertas restricciones. Este servidor
también las atiende.

%description -l pl.UTF-8
Serwer DHCP (Dynamic Host Configuration Protocol).

DHCP to protokół pozwalający urządzeniom pracującym w sieci IP na
pobieranie ich konfiguracji IP (adresu, maski podsieci, adresu
rozgłoszeniowego itp.) z serwera DHCP. Ułatwia on administrowanie
dużymi sieciami IP.

endereços IP alocados dinamicamente, permite também descobrir

funcionalidade similar, com certas restrições. Este servidor também
atende aquelas requisições. Esta versão é ainda considerada um
software BETA.

%description relay
Dhcp relay is a relay agent for DHCP packets. It is used on a subnet
with DHCP clients to "relay" their requests to a subnet that has a
DHCP server on it. Because DHCP packets can be broadcast, they will
not be routed off of the local subnet. The DHCP relay takes care of
this for the client.

%description relay -l pl.UTF-8
Agent przekazywania DHCP (Dynamic Host Configuration Protocol) między
podsieciami. Ponieważ komunikaty DHCP mogą być przekazywane w formie
rozgłoszeniowej, bez tego agenta nie zostaną przerutowane do innej
podsieci.

%description devel
Includes OMAPI and dhcptl libraries.

OMAPI is an programming layer designed for controlling remote
applications, and for querying them for their state. It is currently
used by the ISC DHCP server.

The dhcpctl set of functions provide an API that can be used to
communicate with and manipulate a running ISC DHCP server.

%description devel -l pl.UTF-8
Zawiera biblioteki OMAPI oraz dhcpctl.

OMAPI to warstwa programowa stworzona do kontroli zdalnych aplikacji i
odpytywania o ich stan. Aktualnie jest używana przez serwer ISC DHCP.

dhcpctl to zbiór funkcji tworzących API, które może być używane do
komunikacji z działającym serwerem ISC DHCP i jego kontroli.

# This patch is required for dhcdbd to function
# CHECK ME: adds -x (formerly -y):
#The -x argument enables extended option information to be created in the
#-s dhclient-script environment, which would allow applications running
#in that environment to handle options they do not know about in advance -
#this is a Red Hat extension to support dhcdbd and NetworkManager.
# however, fedora doesn't have this patch anymore, so can drop?
