scapy import error

[15871722713]

I use command 'pip install scapy' to install scapy , and it install sucessful (C:\Program Files\IronPython 2.7\Lib\site-packages\scapy).
It's failed to import scapy in ironpython , but it's ok in python.

from random import randint
from config_read import get_config_by_name
from scapy.all import *

error information is .
ipy test_mac_capacity_test.py

AttributeError: 'module' object has no attribute 'uname'

I use windows 10 and IronPython 2.7.9 (2.7.9.0) on .NET 4.0.30319.42000 (64-bit).

In "C:\Program Files\IronPython 2.7\Lib\site-packages\scapy\consts.py"
WINDOWS = platform.startswith("win32")
if WINDOWS:
try:
if float(platform_lib.release()) >= 8.1:
LOOPBACK_NAME = "Microsoft KM-TEST Loopback Adapter"
else:
LOOPBACK_NAME = "Microsoft Loopback Adapter"
except ValueError:
LOOPBACK_NAME = "Microsoft Loopback Adapter"
LOOPBACK_INTERFACE = None
else:
uname = os.uname()
LOOPBACK_NAME = "lo" if LINUX else "lo0"
LOOPBACK_INTERFACE = LOOPBACK_NAME

sys.platform = cli in ironpython but it is 'win32' in python.

I need to use scapy to send packets , so could you give me some suggestions。

You could try adding the following at the top of your script:

class DualPlatform(str):
    def __eq__(self, other):
        return str.__eq__(self, other) or str.__eq__("cli", other)
    def __ne__(self, other):
        return str.__ne__(self, other) and str.__ne__("cli", other)

import sys
sys.platform = DualPlatform("win32")

[15871722713]

class DualPlatform(str):
def eq(self, other):
return str.eq(self, other) or str.eq("cli", other)

def __ne__(self, other):
    return str.__ne__(self, other) and str.__ne__("cli", other)

import sys
sys.platform = DualPlatform("win32")

from scapy.all import *

I add this at the top of my script , but there is other errors.

Looks like an issue with ctypes. I was able to get around the issue by modifying the scapy source but then I immediately hit another ctypes issue. This will likely require a bit of time debugging...

[valentinbreiz]

I have a problem with ctypes too.
When I use "import ctypes" in a python script launched with Ironpython I have an exception "No module named ctypes".

[slozier]

@valentinbreiz Your problem is unrelated to this particular issue. It sounds more like you're missing the standard library?

[slozier]

The crash appears to occur when passing a pointer that was created using ctypes.cast. Here's a repro for the ipy crash:

import ctypes

class POINT(ctypes.Structure):
    _fields_ = [('x', ctypes.c_long), ('y', ctypes.c_long)]

buf = ctypes.create_string_buffer(ctypes.sizeof(POINT))
ptr = ctypes.cast(buf, ctypes.POINTER(POINT))
ctypes.windll.user32.GetCursorPos(ptr)
print(ptr.contents.x, ptr.contents.y)
