python 多线程扫描大批机器端口

代码如下：

#!/usr/bin/env pythonimport socketfrom time import sleepimport Queueimport threadingdef put_queue(q):    with open('D:/vim/alllist','rb') as f:for line in f:#print 'Put %s to queue' % ([line.split()[2],line.split()[4]]) q.put([line.split()[2],line.split()[4]],block=False)def get_queue(q,file):while True:if not q.empty():value = q.get(block=False)ip = value[0]port = value[1]#command = "sleep 1 | telnet %s %s" % (value[0],value[1])#proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE,shell=True)#res = proc.stderr.read()#if res.endswith('refused\n'):#print "%s %s connected refues" % (value[0],value[1])sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)sk.settimeout(5)try:sk.connect((ip,int(port)))except Exception:                                temp = "Server %s port %s not connect!" % (ip,port)                                file.write(temp+'\n')                                file.flush()sk.close()else:breakif __name__ == '__main__':    f = open('D:/vim/failfile','a+')    f.truncate()q = Queue.Queue()t1 = threading.Thread(target=put_queue,args=(q,))t1.setDaemon(True)t1.start()sleep(1)num = 10threads = []for i in xrange(0,num):threads.append(threading.Thread(target=get_queue,args=(q,f,)))for t in threads:t.setDaemon(True)t.start()for t in threads:t.join()        f.write("done")        f.close()
