Scapy AttributeError on every call: 'module' object has no attribute '*'

Question

I have installed Scapy from the package repos on my Ubuntu machine (Python 2.7), and I am trying to run this code from a file:

import scapy
dg = scapy.IP()
pcap = scapy.rdpcap("../tst/Http.cap")
scapy.send(IP())

Running gives the error, AttributeError: 'module' object has no attribute 'IP'

Comment out the IP call on line 3 and running gives the error, AttributeError: 'module' object has no attribute 'rdpcap'

Also comment out line 4 and you get, AttributeError: 'module' object has no attribute 'send'

Curously, this code fails when invoked with ''python '', but it works as expected when I manually enter each command into the Python shell. I have observed this behaviour on three fresh Python installs - two in Ubuntu, and one in Windows. Can anyone else see the cause of this error?

You need to import Scapy into the global namespace.

From the Scapy module documentation -

Note: In Scapy v2 use from scapy.all import * instead of from scapy import *.

Also found in "Using Scapy to build your own tools".

So your code should be -

from scapy.all import *

dg = IP()
pcap = rdpcap("../tst/Http.cap")
send(IP())

Hi, thanks for your reply. I've made that change, but the error persists.
