*isc-dhcpd の作成
Solaris8 07/03 + gcc な環境
**ソース
-dhcp-3.0pl2.tar.gz
**コンパイル,インストール
% ./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.
起動ファイルのコピー
# sed s/@PREFIX@/\\/usr/g contrib/solaris.init | \
sed s/usr\\/etc\\/dhcpd.pid/etc\\/dhcpd.pid/g \
> /etc/init.d/isc-dhcpd
# chmod +x /etc/init.d/isc-dhcpd
# ln -s ../init.d/isc-dhcpd /etc/rc2.d/S99isc-dhcpd
# ln -s ../init.d/isc-dhcpd /etc/rc0.d/K01isc-dhcpd
# vi /etc/init.d/isc-dhcpd
----------------------------------------------------
# start) のところに以下のものを加えておく.
if[ -f /etc/dhcpd.pid ]; then
rm /etc/dhcpd.pid
fi
----------------------------------------------------
//----------------------------------------------------
**設定
servers/dhcpd.conf にサンプルの設定ファイルがあるので，
これを利用する．
# cp server/dhcpd.conf /etc
# vi /etc/dhcpd.conf
-------------------------------------------------------------
# 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;
ddns-update-style none;
default-lease-time 6000;
max-lease-time 72000;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# This is a very basic subnet declaration.

#
subnet 172.16.0.0 netmask 255.255.0.0 {
range 172.16.1.1 172.16.1.253;
option routers 172.16.0.10;
#

}

primary 172.16.0.11;
}
}
#
# Dafault VLAN
#
subnet 192.168.0.0 netmask 255.255.255.0 {
default-lease-time 300;
max-lease-time 300;
range 192.168.0.100 192.168.0.199;
option routers 192.168.0.1;
}

**フェイルオーバの設定
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;
ddns-update-style none;
default-lease-time 6000;
max-lease-time 72000;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
#authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# This is a very basic subnet declaration.
#
# Authenticated VLAN
#
subnet 172.16.0.0 netmask 255.255.0.0 {
pool{ # <--このあたり
deny dynamic bootp clients; # <--このあたり
range 172.16.1.1 172.16.1.253;
option routers 172.16.0.10;
failover peer "test"; # <--このあたり
} # <--このあたり
}
#
# Dafault VLAN
#
subnet 192.168.0.0 netmask 255.255.0.0 {
pool{ # <--このあたり
deny dynamic bootp clients; # <--このあたり
default-lease-time 300;
max-lease-time 300;
range 192.168.0.100 192.168.0.199;
option routers 192.168.0.1;
failover peer "test"; # <--このあたり
} # <--このあたり
}
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．

# dhcpd.conf for primary

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