Solaris8 07/03 + gcc な環境
% ./configure % make # make install
これで, /usr/sbin/ 以下に dhcpd など, 関係するコマンドがインストールされる.

tests/failover/ 内にフェイルオーバをする時の 設定ファイルのサンプルがある．
ます，現行の設定を共通の設定とするため，
# mv /etc/dhcpd.conf /etc/dhcpd-master.conf
として，名前を変えておく． そして，failover 用の設定も加えておく
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
# option definitions common to all supported networks...
option domain-name "XXX.example.jp";
option domain-name-servers 172.16.0.11;

これを，お互いのサーバにコピーし，設定ファイル中で 読み込んで使う．

一番最初に起動する前には
# touch /etc/dhcpd.leases
をしておくこと．
