No icmp socket available, connect permission denied

[jptang0924]

In my device, When I run these PoC, the output is below:
shell@android:/data/local/tmp $ ./poc
Creating target socket...>>>> max_fds:4096

create_child pid:102784 pipe_read:3 num_socks_created:0
.socks[num_socks] == -1
errno: 13
OK
0 + 0 sockets created
pipe_reads[0]:3 pids[0]:24455
No icmp socket available

And I find at line 388 in pos.c, function create_icmp_socket() return -1, I know that this is because socket connect failed and the errno is equal to 13 which means permission denied.

What is the problem with the connect and how can I resolve that?
Please some one help me.

Thanks in advance
