約10秒後にインターネット接続が失われる
さて、私はこの投稿を見ました ネットワーク接続は数秒後にドロップします 、
これは私が抱えている問題に似ていますが、Linuxを入手したばかりで、何をすべきか理解できません。
始める前に。
私はOpenSUSE13.1を持っています。
これは仮想マシンで実行されています。
ネットワークの私のVMの設定はNATです。
問題
VM起動すると、約10秒間インターネットにアクセスできます。

なぜこれが起こっているのか誰かが知っていますか？
それとも、これに対する解決策がありますか？
また、さらに情報が必要な場合は、必要な情報をお知らせください。探してみます。

仮想マシンでopenSUSE13.132ビットを使用した新規インストールでも同じ症状が発生しました。私にとっての解決策は次のとおりです。
/usr/lib/systemd/system/network.serviceを編集し、提案されているように、[Service]セクションでType=oneshotではなくType=forkingを設定します ここ
