How to send custom tcp packets on windows?

Question

I want to send a packets which I define the ip address, port, data, .etc, at first I thought maybe I can use raw sockets on windows, but after googling for a while, I found that it seemed ms has disabled raw sockets from XP SP2 (is it really?), now I don't know how to do. Someone tells me to use winPcap, then I go to the home page of that software, only to find the last version of that software was released on 02 jul 10, which is too old, I dont know whether it still works now. If possible, I preferred to use Python to complete the task, but it seems inconvenient to use python to realize the raw socket, now I don't know how to do it. Does anyone have a good idea about it? any help appreciated.

And does socket.socket not fit your need? – Thomas Orozco Mar 01 '12 at 12:06 — Thomas Orozco, Mar 01 '12 at 12:06

Have you tried something like

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_RAW)
s.sendto('\xff'*6 + '\x00\x50\xe4\x59\xd9\x30'*16, ('168.1.0.0', 4444))

The documentation for the socket module reads (last example) "The example requires administrator privileges to modify the interface", so you might want to check out how to do this.

thx a lot, but i mean that i want to send to the specific ip address using specific port, IOW i want to camouflage an application to send the packets – Searene Mar 01 '12 at 12:46
Yeah, but someone said that codes Raw socket using python may not be as convenient as C, so i am considering which language should i use, and just as what i have said above, it seems that ms has disabled raw socket from XP SP2, so i dont know whether it does work now. have you ever used `socket.SOCK_RAW` before? @Kimvais – Searene Mar 01 '12 at 12:50

This works at least on Win7 when the python is run as administrator:

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_RAW)
s.sendto(b"\x00"*16, (192.168.0.255, 0)

can you give a more detail example? e.g. i want to edit each part of that packet, can python realize it? – Searene Mar 01 '12 at 15:08
