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
