1 question: dnsmasq: failed to create listening socket for port 53: Address already in use??

solutin:

在/etc/dnsmasq.conf打開bind-interfaces

2.dnsmasq: failed to create listening socket for 127.0.0.1: Address already in use??

solution:

* 編輯 /etc/NetworkManager/NetworkManager.conf
* 註釋掉：dns=dnsmasq （前面加#號註釋）
* 重啓network-manager(sudo restart network-manager)
* 編輯 /etc/dnsmasq.conf
* 添加： listen-address=127.0.0.1
* 重啓dnsmasq (sudo /etc/init.d/dnsmasq restart)
* 可能會報錯：dnsmasq: unknown interface wlan0但是好像也沒啥影響。
