本文实例为大家分享了python编写简单端口扫描器的具体代码，供大家参考，具体内容如下

直接放代码

此代码只支持扫描域名，要扫描IP请自己修改

from socket import *from threading import Threadimport optparsePort = [80,21,23,22,25,110,443,1080,3306,3389,1521,1433]Server = ['HTTP','FTP','TELNET','SSH','SMTP','POP3','HTTPS','SOCKS','MYSQL','Misrosoft RDP','Oracle','Sql Server']def Scan(tghost,tgport,Server):  try:    s=socket()    s.connect((tghost,tgport))    print(tghost+'____>'+str(tgport)+' open',end='||||| ')    print(str(tgport)+'---->'+Server)    s.close()  except:    print(str(tgport)+'----> '+'not open')def hostToaddr(host):#将域名转成ip  try:    return gethostbyname(host)  except:    return def main():  parser=optparse.OptionParser()  parser.add_option('-t', dest='dname')  #parser.add_option('-p',dest='pname')  (options,args)=parser.parse_args()  if(options.dname==None):    print('[-] You must specify a target host and port')    exit(0)  else:    tgname=options.dname  ip=hostToaddr(tgname)  #Scan(ip)  for i,j in zip(Port,Server):#用线程提高速度    t=Thread(target=Scan,args=(ip,i,j))    t.start()  input()#cmd界面如果快速闪退，请加入这条代码if __name__=='__main__':  main()
