重新连接Netgear DGN2200v4的Python脚本

Question

我需要一个脚本为我的Netgear DGN2200v4，让我改变ip每x秒。在网上搜索我发现以下代码：

    #!/usr/bin/env python2.7

import re
import urllib2
from base64 import b64encode
from time import sleep

BASE_URL = 'http://192.168.0.1/'
USERNAME = 'admin'
PASSWORD = 'admin'

id_regex = re.compile('setup.cgi\?id=(\w+)"')

auth = "Basic %s" % b64encode("%s:%s" % (USERNAME, PASSWORD))

def load_html(url, data = None):
    request = urllib2.Request(BASE_URL + url, data,
                              {"Authorization": auth})
    result = urllib2.urlopen(request)
    return result.read()

# Evito eccezione Unauthorized
try:
    load_html('')
except urllib2.HTTPError:
    pass

# Chiamo la schermata di riepilogo
html = load_html('setup.cgi?next_file=RST_st_poe.htm')
ID = id_regex.search(html).group(1)

# Lancio la disconnessione
load_html('setup.cgi?id=' + ID,
          'todo=disconnect&this_file=RST_st_poe.htm&next_file=RST_st_poe.htm&SID=')

# Attendo 3 secondi
sleep(3)

# Chiamo la schermata di riepilogo
html = load_html('setup.cgi?next_file=RST_st_poe.htm')
ID = id_regex.search(html).group(1)

# Lancio la riconnessione
load_html('setup.cgi?id=' + ID,
          'todo=connect&this_file=RST_st_poe.htm&next_file=RST_st_poe.htm&SID=')

# Attendo 7 secondi
sleep(7)

# Logout
load_html('setup.cgi?todo=logout')

但它在我的电脑上不工作。 我已经改变了'用户名'和'密码'与我的凭证和设置PPPOE协议，这是日志。你知道吗

Traceback (most recent call last):
  File "C:\Users\x\Documents\dgnd3700.py", line 31, in <module>
    html = load_html('setup.cgi?next_file=RST_st_poe.htm')
  File "C:\Users\x\Documents\dgnd3700.py", line 19, in load_html
    result = urllib2.urlopen(request)
  File "C:\Python27\lib\urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 397, in open
    response = meth(req, response)
  File "C:\Python27\lib\urllib2.py", line 510, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:\Python27\lib\urllib2.py", line 435, in error
    return self._call_chain(*args)
  File "C:\Python27\lib\urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "C:\Python27\lib\urllib2.py", line 518, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 404: Not Found

我该怎么解决？谢谢你的建议

从回溯看来，连接和授权是成功的，但是

html = load_html('setup.cgi?next_file=RST_st_poe.htm')

不正确，因此出现404错误。你知道吗

可能安装wireshark或fiddler，开始跟踪，然后手动运行这些步骤（使用web浏览器）并查看请求的路径。然后可以修改load\uhtml函数的条目，以反映找到的正确路径。你知道吗
