这篇文章主要为大家详细介绍了Python3多线程版TCP端口扫描器,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

本文实例为大家分享了Python3多线程版TCP端口扫描器的具体代码,供大家参考,具体内容如下

使用命令

python BannerDemo.py -H 192.168.200.101 -p 22,3306

代码如下

import optparse
import socket
from socket import *
from threading import *

screenLock = Semaphore(value=1)

def connScan(tgtHost,tgtPort):
  try:
    connSkt = socket(AF_INET,SOCK_STREAM)
    connSkt.connect((tgtHost,tgtPort))
    connSkt.send('ViolentPython\r\n'.encode('utf-8'))
    result = connSkt.recv(1024)
    screenLock.acquire()
    print("[+] %d/tcp open"%tgtPort)
    print("[+]"+str(result))
  except Exception as e:
    screenLock.acquire()
    print(e)
  finally:
    screenLock.release()
    connSkt.close()


def portScan(tgtHost,tgtPorts):
  try:
    tgtIp = gethostbyname(tgtHost)
  except:
    print("[-] Cannot reslove '%s' : Unknown host" % tgtHost)
    return

  try:
    tgtName = gethostbyaddr(tgtIp)
    print("\n [+] Scan Result for: " + tgtName[0])
  except:
    print("\n [+] Scan Result for: " + tgtIp)

  setdefaulttimeout(1)
  for tgtPort in tgtPorts:
    print("Scanning port "+ tgtPort)
    t = Thread(target=connScan,args=(tgtHost,int(tgtPort)))
    t.start()

def main():
  parser = optparse.OptionParser("usage%prog -H <target host> -p <target port>")
  parser.add_option('-H',dest='tgtHost',type='string',help='specify target host')
  parser.add_option('-p',dest='tgtPort',type='string',help='specify target port[s] separated by comma')
  options,args = parser.parse_args()
  tgtHost = options.tgtHost
  tgtPorts = str(options.tgtPort).split(',')
  if(tgtHost == None or tgtPorts[0] == None):
    print("[-] You must specify a target host and port[s]")
    exit(0)
  portScan(tgtHost,tgtPorts)

if __name__ == '__main__':
  main()
