bat批处理笔记（四）-netsh命令

          netsh(Network Shell)是一个windows系统本身提供的功能强大的网络配置命令行工具，可用来修改windows的ip,网关，dns，防火墙等信息.

1.netsh修改ip,网关，dns:

(1)备份网络配置:

netsh dump > 路径

(2)设置静态ip:

netsh interface ip set address name="WLAN" source=static 192.168.2.188  255.255.255.0 192.168.2.1
rem ip:192.168.2.188;mask:255.255.255.0;gateway:192.168.2.1

netsh interface ip set dns "WLAN" static 192.168.2.1 primary        rem 主dns

netsh interface ip add dns "WLAN" 192.168.1.1                       rem 副dns

(3)设置dhcp:

netsh interface ip set address name="WLAN" source=dhcp

netsh interface ip set dns "WLAN" dhcp                              rem 设置dns

 

2.netsh修改防火墙设置:

(1)开启/关闭:

netsh firewall set opmode mode=disable                     rem 关闭防火墙

netsh firewall set opmode mode=enable                      rem 开启防火墙

查看防火墙cmd中可输入firewall.cpl查看防火墙状态验证.

(2)规则设置:

firewall:           防火墙配置的简单模式;

advfirewall:     防火墙配置的高级模式

dir:                  in/out

netsh firewall set portopening TCP 3389 ENABLE

netsh firewall delete portopening TCP 3389

netsh advfirewall firewall add rule name=baidujingyan dir=in action=allow protocol=TCP localport=3389

netsh advfirewall firewall delete rule name=baidujingyan  protocol=TCP localport=3389

 

3.netsh查看已连接过的历史wifi密码:

netsh wlan show profiles                                       rem 查看当前系统已经保存的网络

netsh wlan show profile name="wifi名称" key=clear              rem 查看指定wifi的密码

 

4.netsh修复网络故障:

netsh winsock reset

         其作用是重置 Winsock目录。如果计算机Winsock协议配置有问题将会导致网络链接等问题，通过重置Winsock目录借以恢复网络.这个命令可以重新初始化网络环境，以解决由于软件冲突,病毒原因造成的参数错误问题》

netsh interface ip reset c:\resetlog.txt

         其作用是重置TCP/IP协议，相当于卸载并重新安装TCP/IP协议，使其恢复到初次安装操作系统的状态.
