Python线程套接字

Question

I'm trying to implement a threading functionality for this answer : Scanning a Class C network Python

So far i have something like this:

...[snip]..
m = re.search("/", str(host))
if m :
   net,_,mask = host.partition('/')
   mask = int(mask)
   net = atod(net)
   for host in (dtoa(net+n) for n in range(0, 1<<32-mask)):
      try:
         mycustomsocket(host)
      except:
         print host+" is down"
         pass
else:
   mycustomsocket(host)

What I'm looking for, would be to open 255 thread to scan all hosts parsed with mycustomsocket() at once, for speed issues.

Any help would be greatly appreciated !

我认为他确实给了您答案，请先阅读文档，然后在对实现线程代码有特定疑问时再回来...如果您阅读已经提到的关于devshed的文章，则可以看到如何创建自己的线程类并将您要使用的IP地址传递到线程中，然后将您的工作代码与某种线程安全队列一起放在该线程中，线程可以在其中放回您所需要的任何信息。

I once wrote a multi-threaded port scanner . Feel free to use it for some ideas on improving performance. Over time, it has been improved and refactored such that it doesn't provide a concise example, but instead implements a more robust implementation with re-usable components. I hope the core ideas aren't masked by the abstraction.

This question is not very specific. It sounds like: "I need threading support for my code, please do the work for me."

Please read the docs about threading in Python and related topics like the Queue class. If you have a more specifc question, come back and ask again.
