最近要架設一台ubuntu電腦，在第一不連網路就卡關了.....感覺ping的到但是瀏覽器到webget或是apt-get update都不可用！
是固定ip的，61.220.248.114~126可用  ...
把設定檔改成這樣
auto lo
iface lo inet loopback

auto enp7s0
iface enp7s0 inet static
address 61.220.248.121
netmask 255.255.255.240
gateway 61.220.248.113
dns-nameservers 168.95.1.1

然後reboot
ifconfig訊息
