What OS can send non native IP address packets ??

What OS can send non native IP address packets?
OR

what tool can implement the function that the machine can send non native IP address packets?

OR

how to configure OS for finishing the function?

A OS that supports raw sockets
a program that will change the IP source header to what ever you want. (google it) or fine something here on GitHub that already has that build in. or just make it with python or something.

Linux already has this pre-enabled on most distributions. Mac no

In MAC OS, I install a virtual ubuntu machine by virtualbox tool.
My Physics Machine: MAC OS,
My virtual Machine: kali and ubuntu OS.
But Virtual machine can't send no native ip address packets.

If i need ubuntu OS physics Machine???

interesting cause when i tried the same thing your talking about it worked. with more than one program using raw sockets. you might have to mess with the networking configuration for virtualbox. so that ubuntu and kali see what your Mac sees. instead of seeing a NAT network or other filtered network. play with it and see what happens.

@merkjinx ,
Penetration Test Env:

Attack Machine : A
victim(target) Machine : B
NTP Machine : C

Command
$ python Saddam.py B --ntp=ntp_ip_address.txt

Phenomenons

I find the phenomeon that the packet can from A Machine to C Machine. the source ip address of all packet are B, and the target ip address of all packet are C.
But
the packet can from C Machine to B Machine.

Why , Can you help me?

Very urgent Problem

I can't understand the cause. Can you explain it for me?

[merkjinx]

that's how NTP reflection works.
from C machines perspective B is sending packets so C responds to B in the same way as a legitimate request. the header of a spoofed packet has source and destination. Which source can be changed to what ever you what. As long as the router of A will route the packet it should work just fine.
also one thing to note is that NTP runs over UDP. which is a connection-less protocol unlike TCP requires a 3 way handshake before any data can be sent.
