Quero primeiro pedir desculpas pelo meu mau inglês ...
Estou encontrando um erro usando o hostapd e mais precisamente com o dnsmasq: quando edito meu /etc/dnsmasq.conf e o atualizo, tenho uma mensagem de erro:
root@bob-E202SA:/home/bob/Scripts# sudo /etc/init.d/dnsmasq restart
[....] Restarting dnsmasq (via systemctl): dnsmasq.serviceJob for dnsmasq.service failed because the control process exited with error code. See "systemctl status dnsmasq.service" and "journalctl -xe" for details.
failed!
Ok, então eu fiz:
root@bob-E202SA:/home/bob/Scripts# systemctl status dnsmasq.service

O Hostapd funciona, posso ver e conectar meu smartphone à Internet, mas as páginas do Google não são carregadas e está escrito "Este site está inacessível" Eu acho que o problema é o dnsmasq, e é devido a essas mensagens de erro ... Obrigado pela sua ajuda!
