ReadyNASでDHCPとDNSを動かす

time 2015/05/31 　所要時間:約 1 分

1 DHCPサーバをインストール
2 DNSをインストール

こんにちは。ちゃぼP（@chabo0429）です。

ReadyNASでは、DHCPサーバとDNSサーバが動くようになっていない。ただし、当然ながらインストールすれば動かすことは出来る。

今回は、それにチャレンジ、

DHCPサーバをインストール

# apt-get -y install dhcp3-server
# vi /etc/dhcp/dhcpd.conf

1 2	# apt-get -y install dhcp3-server # vi /etc/dhcp/dhcpd.conf

13行目

option domain-name "yourdomain.jp";
option domain-name-servers 192.168.100.10;

1 2	option domain-name "yourdomain.jp"; option domain-name-servers 192.168.100.10;

最終行に追記

subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.100.100 192.168.100.200;
}

subnet 192.168.100.0 netmask 255.255.255.0 {

option routers 192.168.100.1;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.100.100 192.168.100.200;

}

# /etc/init.d/isc-dhcp-server restart

1	# /etc/init.d/isc-dhcp-server restart

DNSをインストール

続いてDNSサーバ。BINDを用いるが、元々アドオンがReadyNASのアプリからダウンロードが可能。ところがモジュールが古いのか、まともに動かない。

なので、こちらも手動での設定となった。
