linux - ping的问题 - socket operation not permitted

好奇怪,我的机器突然不能用普通用户ping 了.

参考:https://forum.artixlinux.org/index.php/topic,1809.0.html

$ ping 59.110.226.103

ping: socket: Operation not permitted

解决办法: 
siwei@siweii5:/usr/local/bin$ sudo sysctl -w net.ipv4.ping_group_range="0 1000"

就可以了.

siwei@siweii5:/usr/local/bin$ ping 59.110.226.103
