1. Use the lsof command line to list all open files # lsof This is a very long list, including open files and networks The above screen contains many columns, such as PID, user, FD, and TYPE. FD - File descriptor The FD column contains such values. cwd - Current working directorytxt - Text filemem - Memory Mapped filemmap - Memory Mapped deviceNumber - It represent the actual file descriptor. For example, 0u, 1w and 3r R indicates read, w indicates write, and u indicates read/write. Type indic

In this article, I'll delve into the most basic part of JavaScript-the execution context (execution). After reading this article, you should be aware of what the interpreter does, why the functions and variables can be used before the declaration, and how their values are determined. 1. ec-execution environment or execution context Each time the controller arrives at the ECMAScript executable code, the controller enters an execution context (a very

to different operating systems and get different returned information. You can write a program to determine and process the program based on the return information of the flight logs, so as to achieve automatic logon of the remote server system. This article will first introduce the technologies used to achieve remote automated login, and then details how to achieve remote login automation between Unix/Linux systems. Introduction to automatic remote system logon Automatic remote logon means tha

The principle of remote connection to Linux Shh remote connection IntroductionCurrently, in almost all of the Internet enterprise environment, the most commonly used Linux to provide remote connection services is the SSH software, ssh is divided into SSH client and SSH server two parts.

There is an array, possibly multidimensional, with some values with special symbols such as "I escaped with recursion plus addslashes () It's not working, help, see what's wrong. $arr =array (' II ', array (' one ' = ' "EC" ', ' =>5 ')); Function T ( $arr) { foreach ($arr as $v) { if (is_string ($v)) { $arr []=addslashes ($v); }else{ T ($v); } } } T ($arr); echo " "; Print_r ($arr); Echo ''; This is how the foreground page is exported. _____

Article Title: Use OpenSSH to remotely manage Linux servers. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. As a Linux system administrator, no one knows about OpenSSH. SSH transmits data over the network in the form of ciphertext, achieving a higher security level. It is a security alternative to the Telnet service, and

1. modify the configuration file etcsshsshd_config of the sshd server and modify some parameters as follows to enhance security. Port3333 uses port 22 by default and changes the listening port to another value (preferably a high port above 1024 to avoid conflict with other common service ports ), in this way, the attacker detection system can be increased to see if sshd is running. 1.
