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 ponto de acesso Wifi virtual] [1] ok eu acho que não vou conseguir ajuda além de dicas não úteis para documentações que eu já li ... !!!!
Esta é a mensagem de erro que recebo quando quero iniciá-lo 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":

!!!! ok eu acho que não vou conseguir ajuda além de dicas não úteis para documentações que eu já li ... !!!!
Você deve primeiro fazer a interface e ter o Ip do servidor DHCP configurado nela. vá para / etc / network / interfaces (se você estiver executando a versão 17 ou anterior) ou você pode usar o netplan (para 18.04). permanecendo toda a configuração estão corretas.
O dhcpd precisa de 2 arquivos para funcionar:
/etc/default/dhcpd.conf - define as interfaces (o que você está perdendo)
e /etc/dhcp/dhcpd.conf - o arquivo que você acabou de terminar
o conteúdo de /etc/default/dhcpd.conf deve ser algo assim:
# /etc/default/dhcpd.conf
INTERFACES="eth0"
Você deve usar journalctl -xe (como a mensagem de erro sugere) para obter informações mais detalhadas sobre o erro real.
Você pode precisar vasculhar para encontrá-lo. Ou você pode executar journalctl -f em um terminal e reiniciar o serviço, que deve gravar na parte final do diário e ficar visível no outro terminal.
