デスクトップ版Ubuntuでネットワーク設定

Posted at

経緯

  • UbuntuでGUI上で固定IPを降った後に,作業をしていたらDNSエラーが出たので困った

結論

$ sudo emacs /etc/network/interfaces
$ sudo emacs /etc/resolvconf/resolv.conf.d/base
を書き直した後,
$ sudo resolvconf -u
で設定を更新する

メモ: それぞれの書き方

/etc/network/interfaces

interface
auto eth0
iface eth0 static  ←dhcpをstaticに変更する
address 192.168.5.10 ←固定するIPアドレス
netmask 255.255.255.0 
network 192.168.5.0
broadcast 192.168.5.255
gateway 192.168.5.1
dns-nameservers hoge fuga

/etc/resolvconf/resolv.conf.d/base

nameserver hoge ← DNSサーバアドレス
nameserver fuga

ぼやき

  • けっこうIP設定してから日にち立ってたのに,pip installが失敗するまできづかなかったのつらい
