昨晚今晚写了两晚，总算把Py Port Scanner 写完了，姑且称之为0.1版本，算是一个Python多线程端口扫描工具。

水平有限，实话中间有一些困惑和不解的地方，代码可能也写的比较乱。有些问题并未找到很好的解决方法，还望大家谅解。速度大家自己试验，我感觉还行。

送上效果图两份，分别是扫单IP和扫IP段：

源码：

复制代码 代码如下:

-- coding: utf-8 --

author = 'Phtih0n'
import threading, socket, sys, cmd, os, Queue

扫描常用端口

PortList = [21, 22, 23, 25, 80, 135, 137, 139, 445, 1433, 1502, 3306, 3389, 8080, 9015]

得到一个队列

def GetQueue(list):
PortQueue = Queue.Queue(65535)
for p in list:
PortQueue.put(p)
return PortQueue

单IP扫描线程个数

nThread = 20

线程锁

lock = threading.Lock()

超时时间

Timeout = 3.0

打开的端口列表

OpenPort = []

class ScanThread(threading.Thread):
def init(self, scanIP):
threading.Thread.init(self)
self.IP = scanIP

def Ping(self, Port):  
    global OpenPort, lock, Timeout  
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
    sock.settimeout(Timeout)  
    address = (self.IP, Port)  
    try:  
        sock.connect(address)  
    except:  
        sock.close()  
        return False  
    sock.close()  
    OpenPort.append(Port)  
    if lock.acquire():  
        print "IP:%s  Port:%d" % (self.IP, Port)  
        lock.release()  
    return True

class ScanThreadSingle(ScanThread):
def init(self, scanIP, SingleQueue):
ScanThread.init(self, scanIP)
self.SingleQueue = SingleQueue

def run(self):  
    while not self.SingleQueue.empty():  
        p = self.SingleQueue.get()  
        self.Ping(p)

class ScanThreadMulti(ScanThread):
def init(self, scanIP, PortList):
ScanThread.init(self, scanIP)
self.List = PortList[:]

def run(self):  
    for p in self.List:  
        self.Ping(p)

u'''Py Port Scanner 0.1 使用说明：
port [port..] 设置扫描的端口，用逗号分隔。
默认：21, 22, 23, 25, 80, 135, 137, 139, 445, 1433, 1502, 3306, 3389, 8080, 9015
example：port 21,23,25
example: port 1000..2000
example: port 80,443,1000..1500
scan [IP] 扫描某一IP地址
example: scan 192.168.1.5
search [IP begin]-[IP end] 扫描某一IP段
example: search 192.168.1.1-192.168.1.100
time [timeout] 设置超时时间，默认为3秒
example: time 5
cls 清楚屏幕内容
listport 打印端口列表
