有些时候，在工作过程中，遇到服务器数量非常多。应用模块部署在不同服务器上。有时维护人员做了模块迁移，而未及时同步至手册中。查找比较困难。于是，产生Python根据应用端口进行探测，获取模块部署。查看服务器开放的服务端口，更好的利用。
代码：import sys
import socket
import optparse
import threading
import queue
class PortScaner(threading.Thread):
def __init__(self, portqueue, ip, timeout=3):
threading.Thread.__init__(self)
self._portqueue = portqueue
self._ip = ip
self._timeout = timeout
def run(self):
while True:
if self._portqueue.empty():
break
port = self._portqueue.get(timeout=0.5)
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(self._timeout)
result_code = s.connect_ex((self._ip, port))
if result_code == 0:
sys.stdout.write("[%d]Scann" % port)
except Exception as e:
print(e)
finally:
s.close()
def StertScan(targetip, port, threadNum):
portList = []
portNumber = port
if '_' in port:
for i in range(int(port.split('-')[0]), int(port.split('-')[1]) + 1):
portList.append(i)
else:
portList.append(int(port))
ip = targetip
threads = []
threadNumber = threadNum
portQueue = queue.Queue()
for port in portList:
portQueue.put(port)
for t in range(threadNumber):
threads.append(PortScaner(portQueue, ip, timeout=3))
for thread in threads:
thread.start()
for thread in threads:
thread.join()
if __name__ == "__main__":
parser = optparse.OptionParser(
'Example: python %prog -i 127.0.0.1 -p 80 n python %prog -i 127.0.0.1 -p 1-100n')
parser.add_option('-i', '--ip', dest='targetIP', default='127.0.0.1', type='string', help='target IP')
parser.add_option('-p', '--port', dest='port', default='80', type='string', help='scann port')
parser.add_option('-t', '--thread', dest='threadNum', default=100, type='int', help='scann thread number')
options, args = parser.parse_args()
StertScan(options.targetIP, options.port, options.threadNum)
