Permission denied

Why do I get We use ICMP socket to send ping packet without sudo
(See this post <https://blog.lilydjwg.me/2013/10/29/non-privileged-icmp-ping.41390.html>
__
by lilydjwg(in Chinese)), however, who(which group) can use this feature
is controled by a kernel parameter: net.ipv4.ping_group_range
.
::
cat /proc/sys/net/ipv4/ping_group_range
1 0
The default value is 1 0
, this means the whose group number from 1
to 0 can use this feature(which means nobody can use this), so you get a
Permission denied .
To fix this, change this variable to a proper range include your group id, like this:
::
[[email protected] pingtop]$ id uid=1000(vagrant) gid=1000(vagrant) groups=1000(vagrant) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[[email protected] pingtop]$ sudo sysctl -w net.ipv4.ping_group_range='0 1001' net.ipv4.ping_group_range = 0 1001
