Introduction: In the current method of acquiring IP, the ifconfig and IP get functions are all intranet IP. Sometimes the need to obtain an external IP, the current practice is to send requests to external servers to resolve the external server response, resulting in their own external network IP. Curl under Linux can do the work for us, of course, not afraid of trouble, you can analyze the HTTP protocol yourself, to achieve the above process. If you'

This example summarizes Python's approach to obtaining native local IP addresses under Windows and Linux. Share to everyone for your reference. The specific analysis is as follows: Python socket contains a wealth of functions and methods to obtain the IP address information of the machine, the gethostbyname method of the socket object can obtain the native IP ad

The hosts is a system file with no extension,The function is to map the host name to the corresponding IP address.When the user executes a ping command (such as Ping www.abc.com), the system will first automatically look for the IP address of the www.abc.com from the hosts file.Once found, the system will immediately ping the corresponding IP, or the system will submit the DNS domain name resolution server for IP address resolution.For quick and easy connection, you can record the domain name an

, All CPUs will immediately enter exception handling, without any delay and wait. This CPU is busy waiting until the process of exception processing is called the CPU collection On native Linux, MCE's file is arch/x86/kernel/cpu/mcheck/mce.c. The core processing function is: Do_machine_check, this is the handler function for int 18 Mce_start is invoked in Do_machine_check to perform a collection of CPUs I
