在使用dnet导入错误的osx上,Scapy安装失败

Question

无法安装Scapy并且需要依赖性.我花了一些时间谷歌搜索解决方案,但所有'解决方案'似乎影响旧版本的Python,或根本不工作.

脚本:

#!/usr/bin/python

import threading
import Queue
import time
from scapy.all import *

class WorkerThread(threading.Thread) :

    def __init__(self, queue, tid) :
        threading.Thread.__init__(self)
        self.queue = queue
        self.tid = tid
        print 'Worker: %d' %self.tid

    def run(self) :
        total_ports = 0
        while True :
            port = 0
            try :
                port = self.queue.get(timeout=1)
            except Queue.Empty :
                print 'Worker %d exiting. %d ports scanned'  %(self.tid, total_ports)

                return

                #Scanning begins

            ip = sys.argv[1]
            response = sr1(IP(dst=ip)/TCP(dport=port, flags='S'), verbose=False, timeout=.2)


            if response :
                if response[TCP].flags == 18 :

                    print 'ThreadID: %d: Got port no. %d status: OPEN' %(self.tid, port)
                self.queue.task_done()
                total_ports += 1

queue = Queue.Queue()

threads = []
for i in range(1, 10) :
    print 'Creating WorkerThread : %d' %i
    worker = WorkerThread(queue, i)
    worker.setDaemon(True)
    worker.start()
    threads.append(worker)
    print 'WorkerThread %d created' %i

for j in range(1, 100) :
    queue.put(j)

queue.join()

for item in threads :
    item.join()

print 'Scanning complete'

Python版本是2.7.5并验证了Python的路径.

which python
/usr/bin/python

执行脚本时,我收到以下错误:

./multi-threaded-scanner.py
Traceback (most recent call last):
  File "./multi-threaded-scanner.py", line 6, in <module>
    from scapy.all import *

  File "/Library/Python/2.7/site-packages/scapy/arch/pcapdnet.py", line 160, in <module>
    import dnet
ImportError: No module named dnet

我可以使用Scapy和Python交互式解释器,并且import scapy在Python解释器中运行不会产生任何错误.当脚本最初运行时,pcapy模块丢失,但我安装了然后问题切换到dnet,我无法找到解决方案. 类似的帖子,似乎描述了同样的问题,但解决方法没有效果.任何人都可以对这个问题有所了解吗？

用于安装pcapy和libdnet的命令:

libdnet-1.11.tar.gz(01-19-2005)

` ~/Downloads/libdnet-1.11  ?  
chmod a+x configure
 ~/Downloads/libdnet-1.11  ?  
./configure  && make`

退出成功

Pcapy:最新稳定版(0.10.8),2010年8月26日更新

~/Downloads/pcapy-0.10.8 ?

使用新标志进行编译的结果

Answer 1

编辑 - 下面的答案说明所有提到的问题都已修复,并提供了一种更简单的安装方法.然而,它的评论表明虽然它似乎适用于OS X 10.10 Yosemite和OS X 10.11 El Capitan,但它可能会因某些其他版本而失败.

您尚未完成安装$ pip install scapy及其Python包装器,如$ pip install --pre scapy[basic]安装指南中所述:

$ brew update  # update Homebrew
$ brew install libpcap  # install libpcap

如果您的系统是64位,请改用以下编译命令:

$ sudo port -d selfupdate  # update MacPorts
$ sudo port install libpcap  # install libpcap

此外,请确认您已安装正确的版本,即1.12而不是1.11.

如果失败,那么尝试通过安装$ pip install --pre scapy[complete]和使用它的from scapy.config import conf; conf.use_pcap = True文件,描述在这里:

$ brew install libdnet --with-python
$ pip install pcapy
$ pip install scapy

该链接还建议更改from scapy.config import conf; conf.use_pcap = True(修复site-packages)中的一些代码.

改变第34​​行:

$ mkdir -p /Users/<USERNAME>/Library/Python/2.7/lib/python/site-packages
$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/<USERNAME>/Library/Python/2.7/lib/python/site-packages/homebrew.pth

至:

$ wget https://github.com/dugsong/libdnet/archive/libdnet-1.12.tar.gz
$ tar xfz libdnet-1.12.tgz
$ ./configure
$ make
$ sudo make install
$ cd python
$ python2.5 setup.py install

如下:

$ CFLAGS='-arch i386 -arch x86_64' ./configure
$ archargs='-arch i386 -arch x86_64' make

如果仍然出现错误sys.path,则尝试对该dnet.so子句的其他分支(特别是其/Library/Python/2.7/site-packages/scapy/arch/unix.py分支)执行类似的更改,如本答案中所述.

Answer 2

上面提到的所有问题似乎都是固定的 我正在运行OS X Yosemite.我通过以下三个命令得到了一个工作scapy.

brew install --with-python libdnet
pip install pcapy
pip install scapy
