Get "NameError: name 'IP' is not defined" error message

Question

I try to run a python code from online course to create a raw network packet and send to a network by scapy with python 3.4.2 on Debian 9 but I got the error message as show below:

NameError: name 'IP' is not defined

when I look into the code:

#!/usr/bin/python

#for python 3 , must install scapy for python3 first by type command "pip3 install scapy-python3"
import scapy.all

frame = scapy.all.Ether(dst="15:16:89:fa:dd:09") / IP(dst="9.16.5.4") / TCP() / "This is my payload"

there is a red line under "IP" and "TCP" method and then It tell that those 2 methods are Unresolved reference

I try to change how to import scapy library

from

import scapy.all

to

from scapy.all import *

but the problem is not resolved. What do I something wrong?

Answer 1

Since you did

import scapy.all

You will have to refer all the types with the 'scapy.all' prefix.

>>> import scapy.all
>>> frame = scapy.all.Ether(dst="15:16:89:fa:dd:09") / IP(dst="9.16.5.4") / TCP() / "This is my payload"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'IP' is not defined
>>> frame = scapy.all.Ether(dst="15:16:89:fa:dd:09") / scapy.all.IP(dst="9.16.5.4") / scapy.all.TCP() / "This is my payload"
>>>

Another way around it is

from scapy.all import *

But that tends top pollute your namespace.

Answer 2

#!/usr/bin/python

#for python 3 , must install scapy for python3 first by type command "pip3 install scapy"
import scapy.all.Ether
import scapy.all.IP
import scapy.all.TCP

frame = Ether(dst="15:16:89:fa:dd:09") / IP(dst="9.16.5.4") / TCP() / "This is my payload"

Answer 3

Okay , this may help you because I did the same mistake. Make sure your filename is not scapy.py

Answer 4

from scapy.layers.inet import IP
