ping: icmp open socket: Operation not permitted Centos 6 LXC

If you are facing an issue with Centos 6.8 template in LXC. Showing you the error

[[email protected] ~]# ping google.com
ping: icmp open socket: Operation not permitted
[[email protected] ~]# ls -l $( which ping );
-rwsr-xr-x 1 100000 100000 38264 May 10  2016 /bin/ping

everything looks ok but you still can't ping. btw, I'm on unprivileged container. Firing the below works for me.

[[email protected] ~]# setcap cap_net_raw+ep /bin/ping

and you should be able to ping after that.
