在osx上安装Scapy失败，出现dnet导入错误
安装Scapy时遇到问题，它是必需的依赖项。我花了一些时间在谷歌上寻找解决方案，但所有的“解决方案”似乎都会影响旧版本的Python，或者根本不起作用。
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版本为2.7.5，并验证了Python路径。
which python
/usr/bin/python当执行脚本时，我得到以下错误：
./multi-threaded-scanner.py

import dnet
ImportError: No module named dnet我可以同时使用Scapy和Python交互式解释器，并且在Python解释器中运行import scapy不会产生错误。当脚本最初运行时，pcapy模块丢失了，但是我安装了它，然后问题切换到了dnet，我找不到解决方案。A similar post，似乎描述了相同的问题，但解决方法没有任何效果。有人能在这个问题上提供更多的信息吗？
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`成功退出
Pcapy:最新稳定版本(0.10.8)，2010年8月26日更新

上面提到的所有问题似乎都得到了解决。我在运行OS X Yosemite。通过以下三个命令，我得到了一个可用的替罪羊。
brew install --with-python libdnet
pip install pcapy
pip install scapyStack Overflow用户

我运行的是OSX 10.5.9 --我花了很长时间尝试让它正常工作--在安装了dnet/pcap库之后，我也收到了"OSError:Device not configured“的提示。已尝试将unix.py中的第34行替换为
"netstat -rn | grep -v vboxnet"
仍然得到相同的错误。但是，当我在if块的"else“部分更改了第37行时：
def read_routes():
if scapy.arch.SOLARIS:
f=os.popen("netstat -rvn") # -f inet
elif scapy.arch.FREEBSD:
f=os.popen("netstat -rnW") # -W to handle long interface names
else:
# f=os.popen("netstat -rn") # -f inet
f=os.popen("netstat -rn | grep -v vboxnet") # -f inet就像一种护身符！

在OSX El Capitan中，对我起作用的是强制pip使用sudo：sudo pip install --user pcapy -I重新安装pcapy。
