Hostapdとisc-dhcpdを使用してWi-Fiアクセスポイントを設定しようとしましたが、dhcpサーバーは機能しません。 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Wi-Fiアクセスポイントを作成する方法] [1]
！ ！ ！それでも問題があります。ドキュメントとマニュアルページを読みました...!!!!

このメッセージはNot configured to listen on any interfaces!あなたの手がかりです。
サービスの開始時にisc-dhcp-serverサービスがアドレスを転送するのと同じサブネットに設定されたネットワークデバイスがない場合は、起動しません。
したがって、インターフェイスがリースプールの範囲（構成に応じて10.0.0.3-10.0.0.13、構成に応じて10.0.0.13）に属さない10.0.0.0/24サブネットのアドレスを持つように、上記の文書を編集して/etc/network/interfaces適切に変更する必要があります。wlan0）。wlan010.0.0.x IP でインターフェイスを呼び出せる場合は、isc-dhcp-serverデーモンを再起動すると正常に動作します。
