python——遍历网卡并禁用/启用

一、遍历网卡

        注意：只能遍历到启用状态的网卡，如果网卡是禁止状态，则遍历不到！！！

import os
import time
import psutil
import loggingdef get_multi_physical_network_card():physical_nic_list = []try:interfaces = psutil.net_if_addrs()for interface_name, interface_addresses in interfaces.items():if all(virtual_pick not in interface_name.lower() for virtual_pick in {"virtual", "vmware", "hyperv"}):for address in interface_addresses:if any(cur_ip in address.address for cur_ip in {"10.", "100.", "169."}):physical_nic_dict = {}physical_nic_dict['name'] = interface_namephysical_nic_dict['address'] = address.addressphysical_nic_list.append(physical_nic_dict)log_str = '当前机器连接网络的网卡名字为:{}, ip:{}'.format(interface_name, address.address)print("\n{}".format(log_str))return physical_nic_listexcept Exception as e:logging.exception(e)return physical_nic_listphysical_nic_list = get_multi_physical_network_card()
for nic_dict in physical_nic_list:print(nic_dict )

二、禁用网卡

        cmd命令：netsh interface set interface "网卡名" admin=enable/disable

import os
import time
import psutil
import loggingdef disable_multi_physical_network_card():try:# 注意此处是引用上面的遍历网卡的函数physical_nic_list = get_multi_physical_network_card()for nic_dict in physical_nic_list:address_ip = nic_dict['address']physical_nic_name = nic_dict['name']disable_cmd = 'netsh interface set interface \"{}\" admin=disable'.format(physical_nic_name)os.system(disable_cmd)logging.info("physical_nic_name: {}, address_ip: {}".format(physical_nic_name, address_ip))except Exception as e:logging.exception(e)

三、启用网卡

        以上方法是遍历网卡名，然后执行cmd命令逐一禁用

        由于目前无法遍历出已禁用的网卡名，所以如果想要启用网卡的话，用上面的方法行不通，建议提前确定好网卡名，不遍历直接cmd
