Hi,

I get this error

$ ./pwnat -s
Listening on UDP 0.0.0.0:2222
Couldn't create privileged icmp socket: Operation not permitted
Couldn't create privileged raw socket: Operation not permitted
Failed to send ICMP packet: Socket operation on non-socket
^Cselect: Interrupted system call
Cleaning up...
Goodbye.

I'm using Linux version 3.10.0-862.14.4.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Wed Sep 26 15:12:11 UTC 2018

You need root to generate those sockets or perhaps CAP_NET_RAW or a similar capability via setcap would allow your user to do it.
