Q:

Controlling packet injection contents at the byte level with Python and Scapy

Is it possible to designate a packet to send with scapy and python, at the byte level?
For instance, instead of building out an 802.11 packet using functionality like scapy.Dot11Elt(), et cetera, before sending, you just scapy.send("\xaa\xbb\x00\x02") 
If so, how is this done?

A:

Use the Raw layer. You can specify the bytes directly.
from scapy.all import *

packet = IP(dst="127.0.0.1")/Raw("\xaa\xbb\x00\x02")
send(packet)

You can use Wireshark to verify that a packet was generated as expected.
