Hostapdとisc-dhcpdでwifiアクセスポイントを設定しようとしましたが、dhcpサーバーが機能しません。confファイルは、このチュートリアルで見つけたものと同じです:[Hostapd:Linuxで仮想Wifiアクセスポイントを作成する方法] [1] !!!! ok私はすでに読んだドクメンテーションの有用なヒント以外に私は何の助けも得ないと思います... !!!!
これは、コマンド「systemctl start isc-dhcp-server.service」または「service isc-dhcp-server start」で開始したいときに表示されるエラーメッセージです。
Job for isc-dhcp-server.service failed because the control process exited with error code.
See "systemctl status isc-dhcp-server.service" and "journalctl -xe" for details.
これは、コマンド「systemctl status isc-dhcp-server.service」の出力です。

最初にインターフェイスを作成し、DHCPサーバーIPを構成する必要があります。/etc/network/interfaces(バージョン17以前を実行している場合)に移動するか、ネットプラン(18.04の場合)を使用できます。残りのすべての構成は正しいです。
dhcpdが機能するには2つのファイルが必要です。/etc/default/dhcpd.conf
-インターフェースを定義します(欠落しているもの)
そして/etc/dhcp/dhcpd.conf
-完成したファイル
/etc/default/dhcpd.conf
の内容は次のようになります。
# /etc/default/dhcpd.conf
INTERFACES="eth0"
