python对C段的端口扫描

再接再厉，继续实现端口的扫描。只需要在上次的代码上做一些修改即可。这次写个对C段的扫描的脚本。

#coding=utf-8

#python2.7

import socket

import threading

import time

ip=raw_input(unicode("请输入IP地址:","utf-8").encode("gbk"))

socket.setdefaulttimeout(1)

lock = threading.Lock()

def scan(ip,port):

try:

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.connect((ip,port))

lock.acquire()

print('[+] %s %d open' % (ip,port))

lock.release()

s.close()

except:

pass

def portscan():

ports=[22,80,443,445,1524,3306]

threads=[]

for p in range(len(ports)):

p=ports[p]

t=threading.Thread(target=scan, args=(ip,p))

threads.append(t)

t.start()

for t in threads:

t.join()

if __name__=='__main__':

for x in range(0,255):

i=ip.rfind('.')

ip=ip[:i+1]+str(x+1)

#print(u'开始扫描%s>>>>>>'% ip)

#t1=time.time()

portscan()

#print(u'扫描端口完成用时 time:%f' % (time.time()-t1))

再看一下格式。

c_port.py

看一下效果图。
