Ubuntuでのresolv.confの扱い

Last updated at Posted at 2014-10-08

ubuntu 12.04 からは、/etc/resolv.confで直接編集は行なわない。

/etc/network/interfacesで以下のように設定する。

/etc/network/interfaces
dns-nameservers 8.8.8.8

再起動で設定が反映される。

shell
sudo service networking restart

dns-nameserversの設定は不要だろうと思って消してしまい、
しばらく経って設定が更新されたタイミングで、名前解決ができなくなってしまってハマった。
