Não é possível iniciar o isc-dhcp-server devido ao erro: Não configurado para escutar em qualquer interface!

2

Eu tento configurar um ponto de acesso wi-fi com hostapd e isc-dhcpd, mas o servidor dhcp não funciona. O arquivo conf é o mesmo que encontrei neste tutorial: [Hostapd: A maneira do Linux de criar um ponto de acesso Wifi virtual] [1]

!!! Ainda tenho o problema e já li o documentaion e man Pages ... !!!!

Esta é a mensagem de erro que recebo quando quero iniciá-la com o comando "systemctl start isc-dhcp-server.service" ou "service isc-dhcp-server start"

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.

Esta é a saída do comando "systemctl status isc-dhcp-server.service":

A mensagem Not configured to listen on any interfaces! é sua pista.

Ao iniciar o isc-dhcp-server , ele não será iniciado a menos que haja um dispositivo de rede configurado para estar na (s) mesma (s) sub-rede (s) para o qual o seu serviço distribuirá endereços.

Portanto, convém editar /etc/network/interfaces e fazer as alterações apropriadas para que sua interface wlan0 tenha um endereço na sub-rede 10.0.0.0/24 que NÃO esteja dentro do intervalo do pool de lease (10.0. 0.3-10.0.0.13 com base no seu arquivo de configuração acima). Uma vez que você pode abrir a interface wlan0 com um IP 10.0.0.x então (re) iniciar o daemon isc-dhcp-server deve funcionar bem.
