Configure System Fire Prevention and network with netsh.exe
(1), View, enable, or disable system firewall
Open the command prompt, enter the command "netsh firewallshow State", and press enter to view the firewall status. The display result shows the disabling and enabling of each functional module of the firewall. The "netsh firewall set opmode disable" command is used to disable the system firewall. The opposite command is "netsh firewall set opmode enable" to enable the firewall.
(2)Allow file and print sharing
Files and printers are commonly used in LAN sharing. To allow clients to access shared files or printers on the local machine, enter and execute the following commands: netsh Firewall add portopening UDP 137 NetBIOS-NS (allow the client to access port 137 of UDP protocol on the server) Netsh Firewall add portopening UDP 138 NetBIOS-DGM (Allow access to UDP port 138) Netsh Firewall add portopening tcp 139 NetBIOS-SSN (Allow access to TCP port 139) after the netsh Firewall add portopening TCP 445 NetBIOS-DS (allow access to TCP port 445) command is executed, all the ports required for file and print sharing are opened by the firewall.
(3)Allow ICMP echo
By default, external hosts are not allowed to ping Windows 7 for security reasons. However, in a secure LAN environment, the ping test is necessary for the Administrator to test the network. How can I allow the ping test echo on Windows 7? Of course, through the system firewall console you can set the file and print share (echo request-ICMPv4-In) rule in inbound rules to allow (if the network uses IPv6, you must also allowICMPv6-In.). However, we can use the netsh command in the command line to quickly implement it. Run the "netsh firewall set icmpsetting 8" command to Enable ICMP Echo. Otherwise, Run "netsh firewall set icmpsetting 8 disable" to disable the echo.
(4)Display Network Interface Information
Netsh interface show Interface
(5), Disable and enable the NIC
Netsh interface set interface name ="Wireless Network Connection "Admin = Disabled &&
Netsh interface set interface name ="Wireless Network Connection "Admin = Enabled
(6)Set the IP address and DNS of the NIC
Netsh interface IP Set addressName ="Local Connection "Source = DHCP
Netsh interface IP Set addressName ="Local Connection "Source = static
ADDR = 192.168.0.10 mask = 255.255.255.0 gateway = 192.168.0.1
Netsh interface IP Add DNSName ="Local Connection"ADDR = 192.168.0.120
(7)Enable "network and Sharing Center"
Control.exe/name Microsoft. networkandsharingcenter
