用Python更改IP地址(转

用Python更改IP地址(转)

大多数用笔记本电脑的朋友都有一个烦恼，那就是在家里和公司的IP地址不一样，上班和回家后都得来回切换IP地址，两个字“麻烦”。最近在写Python，于是在网上查找是否Python能够胜任这份造福的工作，很幸运，找到了，这是网络上的一个实现方法，经测试通过，大家可以使用。

注：需要下面两个模块的支持，请朋友们下载自行安装。

Tim Golden对WMI的包装模块

Python for Windows extensions(pywin32)

源码如下：

# -*- coding: cp936 -*-
#
# FileName: ModifyIP.py
# Date : 2008-01-15

import wmi

print ‘正在修改IP,请稍候‘

wmiService = wmi.WMI()
colNicConfigs = wmiService.Win32_NetworkAdapterConfiguration(IPEnabled = True)

#for objNicConfig in colNicConfigs:
#    print objNicConfig.Index
#    print objNicConfig.SettingID
#    print objNicConfig.Description.encode(“cp936”)
#    print objNicConfig.IPAddress
#    print objNicConfig.IPSubnet
#    print objNicConfig.DefaultIPGateway
#    print objNicConfig.DNSServerSearchOrder

if len(colNicConfigs) < 1:
    print ‘没有找到可用的网络适配器‘
    exit()
objNicConfig = colNicConfigs[0]

#for method_name in objNicConfig.methods:
# method = getattr(objNicConfig, method_name)
# print method

if returnValue[0] == 0:
    print ‘设置IP成功‘
