How to Manage Kernel Modules in Linux with `modprobe`
modprobe is the core tool in Linux for loading, uninstalling and managing kernel modules. It can automatically handle module dependencies. 1. Use the command sudomodprobemodule_name to load the module. For example, sudomodprobenfs will automatically load nfs and its dependencies such as sunrpc. 2. Use sudomodprobe-rmodule_name to uninstall the module. For example, sudomodprobe-rnfs will remove nfs and unused dependent modules, provided that the module is not occupied. 3. Check the module status by lsmod|grepmodule_name to check whether it has been loaded, and use modinfomodulu to

Windows 10 can't set static IP address
To successfully set up Windows 10 static IP, you must first use the correct network settings interface and avoid common problems: 1. Enter Win I→Network and Internet→Ethernet or Wi-Fi→Edit IP assignment manually, enter the correct IP address, subnet mask, gateway and DNS and save it; 2. Make sure that the selected IP is not within the router's DHCP range to avoid IP conflicts, and at the same time confirm that the current account has administrator rights and check whether the network allows static IP settings; 3. If the graphical interface fails, you can use the command prompt for administrator rights to run the netsh command to set IP and DNS; 4. If the settings cannot be saved, execute ipconfig/release and ipconfig in turn

Troubleshooting Windows Hello PIN setup errors
If there is an error in setting Windows HelloPIN, you can follow the steps to troubleshoot. 1. If the prompt "cannot set", check whether TPM is enabled, run sfc/scannow to repair system files, and try to switch local accounts. 2. When the settings are successful but cannot be logged in, restart the device, clear the PIN cache, and check whether the Group Policy restricts PIN login. 3. When encountering "PIN does not meet the complexity requirements", simple numbers and obvious differences from old PINs should be avoided. Professional users can enable the "Allow Simple PIN" strategy at their discretion. Handle it step by step in this order, and most problems can be solved.

A Deep Dive into the Linux Kernel Networking Stack
The Linux network stack is packaged into the softnet_data queue through netif_rx()/NAPI from the network card driver; 2.net_rx_action() is processed and distributed to the protocol layer such as ip_rcv(), supporting eBPF filtering; 3. IP layer verification and routing search, and locally send to the transport layer, otherwise forwarding; 4. TCP/UDP delivers applications according to the socket queue, and rmem_max affects UDP packet collection performance. Understanding this process can accurately locate packet loss and optimize performance, which is a necessary foundation for practical combat.
