bind10で権威サーバ設定

bind10.1.2

b10-authの設定

 権威サーバはオプション扱いなので、追加する。これだけでも結構苦労する。コンポーネントの名前がバージョンによって異なるのだ。10.1.2.0だとinitという名前だった。


 何はともあれ、本体を起動しておく。

# /usr/local/sbin/bind10 -u named &


 なんだか昔のcisco iosとかアライドテレシスの高級機をいじってる懐かしい記憶が蘇る。なんでまたこんなセンスの欠片もないコマンドを使わなきゃいかんのだ。tab補完も何もねぇくせにちょっと間違うとエラーで怒られる。

ゾーンの設定

 SQLiteはわからないので、zoneファイルを作り直す感じでいく。

 ダメだ。systemd経由の起動が必ず失敗するし、失敗理由もよくわからんなぁ。yum update systemdしても最新なんだよね。
 DNSサーバ本体だけISPDNSに向けてフォワーディングしたいんだけど、それもわからん。
