最近想更新升级一下搞事的Parrot，但是发现联不了网了。。。
之前经常遇到。。。立马就想到是哪儿出了问题，DNS解析又玩儿完了
修改 /etc/resolv.conf
删掉所有的 nameserver 并添加一个国内的DNS解析
nameserver 114.114.114.114
当然你也可以加上4.4.4.4和8.8.8.8
之后重启networking
sudo service networking restart
或者使用官方的
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
search localdomain
# ParrotDNS/OpenNIC AnyCast IPs
nameserver 185.121.177.177
nameserver 169.239.202.202
nameserver 198.251.90.108
nameserver 198.251.90.109
nameserver 198.251.90.110
