Hostapd 및 isc-dhcpd를 사용하여 Wi-Fi 액세스 포인트를 설정하려고 시도했지만 dhcp 서버가 작동하지 않습니다. conf 파일은 이 튜토리얼에서 찾은 것과 동일합니다: [Hostapd: Linux에서 가상 Wi-Fi 액세스 포인트를 생성하는 방법][1]

"systemctl start isc-dhcp-server.service" 또는 "service isc-dhcp-server start" 명령을 사용하여 시작하려고 할 때 나타나는 오류 메시지입니다.
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.

답변1
이 메시지가 Not configured to listen on any interfaces!당신의 단서입니다.
시작할 때 isc-dhcp-server서비스가 주소를 전달할 동일한 서브넷에 있도록 구성된 네트워크 장치가 없으면 시작되지 않습니다.
따라서 인터페이스가 임대 풀 범위(구성에 따라 10.0.0.3-10.0.0.13, 구성에 따라 10.0.0.13)에 속하지 않는 10.0.0.0/24 서브넷의 주소를 갖도록 위 문서를 편집 /etc/network/interfaces하고 적절하게 변경 해야 합니다. wlan0). wlan010.0.0.x IP로 인터페이스를 불러올 수 있으면 isc-dhcp-server데몬을 (다시) 시작하면 제대로 작동합니다.
답변2
다음 명령을 사용하여 wlan NIC에 IP 주소를 추가하십시오.
ifconfig wlan0 10.0.0.1
답변3
나에게도 같은 문제가 있었고 나에게 도움이 된 방법은 eth0서브넷(내 네트워크 인터페이스의 이름)을 파일의 서브넷 선언으로 추가하는 것이었습니다 dhcpd.conf.
귀하의 경우 서브넷 선언은 다음과 같아야 합니다.
subnet 10.0.0.0 netmask 255.255.255.0 {
option routers 10.0.0.14;
}
