bind：zoneファイルの修正方法について（必須メモ）

1)赤文字の箇所を修正する。
変更したい箇所：digihide.local  ->digihide2.local

ポイント：TTLとserialの値を変更しないとbind自体

ゾーンファイルの変更をしてくれないようだ！！

vi /var/named/chroot/var/named/1.168.192.in-addr.arpa.zone

=============1.168.192.in-addr.arpa.zone===========

$TTL 1

@       IN SOA  digihide2.local. root.digihide2.local. (

                                        11      ; serial

                                        1D      ; refresh

                                        1H      ; retry

                                        1W      ; expire

                                        3M )    ; minimum

                NS      ns.digihide2.local.

111     IN      PTR     digihide2.local.

=====================================================

2)サービスを再起動を行うと先ほど変更したserial 11になっていることが確認できる。

systemctl restart named-chroot

======================================================

3)先ほど、修正した箇所が反映されていることが分かる。

nslookup 192.168.1.111

===================================

Server: 192.168.1.111

Address: 192.168.1.111#53

111.1.168.192.in-addr.arpa name = digihide2.local.
