BIND起動/動作確認2015/05/27

[1]	BINDを起動します。また、名前解決の参照先も自身に変更しておきます。

[root@dlp ~]#

systemctl start named

[root@dlp ~]#

systemctl enable named

# 参照するDNSを変更 (デバイス名は自身の環境に置き換えてください)

[root@dlp ~]#

nmcli c modify eno16777736 ipv4.dns 10.0.0.30

[root@dlp ~]#

nmcli c down eno16777736; nmcli c up eno16777736

# リスン状況確認

[root@dlp ~]#

ss -napt
