I. Introduction When the Linux kernel crashes or the server hangs, kdump (kernel crash dump: the kernel crash dump device) generates the vmcore file, and analyzes the vmcore information to determine the cause, crash is a widely used kernel crash dump file analysis tool, which requires the system to install the crash tool and kernel debugging tool kernel-debuginfo. Ii. Tool installation and debugging 1. The version of the installation package must be consistent with that of the Linux kernel. view

process of active FTP is as follows:1. The customer issues a command to establish a data connection.2. the customer usually selects a temporary port number for the data connection on the client host. The customer publishes a passive open request from the port.3. The customer uses the PORT command to send the port of the data channel to the server from the command channel.4. The server receives the port number on the Command Channel and sends an active open request to the port on the client host

The day before yesterday, a netizen asked about the design mode of the adapter mode (Adapter), said not very good understanding. Can insus.net give a simple example to illustrate. The following animation is the result of insus.net: The above demo, two lamps of the same specification, requires the input voltage of 15 volts. LIGHT1 is used directly, while LIGHT2 is using adapter (power adapter). So Light1 can only receive 15 volts of voltage, less than 15 volts, will prompt the voltage is too lo

These problems can be solved using an auxiliary array, also known as an accompanying array. 1. Prime Number Evaluate the prime number: sort the integers in a range starting from 1 in ascending order. 1 is not a prime number. First, sieve it out. In the remaining number, select the smallest number as the prime number, and then remove its multiples. And so on until the sieve is empty. void prime(int n){vector 2. affinity (reference) If the sum of two integers, each of which is exactly the same a
