静的IPを使用してインターフェイスにエイリアスを追加する方法

静的IPを使用してインターフェイスにエイリアスを追加する方法

私はUbuntu 16.04 LTSで働いています。静的IPを使用してインターフェイスにエイリアスを追加するには、docker xdebugが必要です。マニュアルで実行するコマンドを見つけました。

sudo ip addr add 10.254.254.254/24 brd + dev eth0 label eth0:1

しかし、私にエラーがありました。

デバイス「eth0」が見つかりません。どのデバイスを使うべきかわかりません。 Wi-Fi経由で会社のネットワークに接続し、ifconfigで次の結果を得ました。

答え1

ip addr add新しいデバイスを作成できません(意図ではない可能性があります)。したがって、最初にエイリアスを追加する既存のデバイスを見つけてから、代わりにその名前を使用する必要がありますeth0
