Ubuntu 17.04 nslookup google ip没问题，为啥ping的都是污染的？ #60
Description
PPTP延迟要求太高，最近一直用OpenVPN，4G上都行。
开机啥都不做，等着OpenVPN连上，只开一终端：
yuangg@broad:~$ nslookup www.google.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: www.google.com
Address: 216.58.194.68
yuangg@broad:~$ ping www.google.com
PING www.google.com (78.16.49.15) 56(84) bytes of data.
^C
--- www.google.com ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4102ms
以前ping一会IP就正常，换到Ubuntu 17.04怎么都不行……
那折腾什么？因为AMD超线程需要新内核……
