** BINDについて [#ldab7c76]
BINDがインストールされており、初期状態では自動起動しない設定となっている。
# chkconfig --list |grep named
named 0:off 1:off 2:off 3:off 4:off 5:off 6:off
# rpm -qa |grep bind

bind-9.3.6-4.P1.el5_4.2
bind-chroot-9.3.6-4.P1.el5_4.2
上記のことからchrootで動くパッケージが初期でインストール済み。

named.conf が提供されていないというか、デフォルトでは存在しないので、キャッシュサーバとして動作するようになっている。
必要な設定をした後、
# chkconfig named on
として、自動起動するように設定すれば良い。
named.conf の書き方については特に触れない。
